Complete study notes for Questioning, Communication and Instructional Materials, written for LET Secondary aspirants. Unlike generic notes, these focus on what Professional Regulation Commission (PRC) actually tests in the LET Secondary Principles and Strategies of Teaching section: high-yield concepts, common question types, and the worked examples that match recent exam patterns.

Exam context

Professional Regulation Commission (PRC) runs the Licensure Examination for Professional Teachers — Secondary on Bi-annual. Its Principles and Strategies of Teaching section sits under a "Core" weighting, and Questioning, Communication and Instructional Materials is the 3rd chapter in the 5-chapter LET Secondary Principles and Strategies of Teaching rotation. The LET Secondary passing mark is Weighted average of 75% with no grade below 50%, and the most recent 2026 paper drew about a meaningful share of questions from Principles and Strategies of Teaching.

Questioning, Communication and Instructional Materials - Study Notes

Effective teaching rests on three interconnected pillars: skillful questioning, clear communication, and well-chosen instructional materials. These tools transform a lesson plan into genuine learning experiences. On the Licensure Examination for Teachers (LET), this chapter is part of the Curriculum, Methods and Strategies, and Educational Technology cluster (30% of Professional Education). Questioning items appear frequently on the exam, testing your ability to identify question types, recognize teaching techniques like probing and redirecting, and evaluate how teachers handle learner responses. Classroom communication skills and the selection and use of instructional materials are equally important for creating an inclusive, engaging learning environment that respects learners' dignity—a key principle under RA 7836, the Code of Ethics for Professional Teachers. Understanding Dale's Cone of Experience and practical selection criteria will help you choose materials that align with learner needs and lesson objectives. This chapter provides the precise vocabulary and conceptual frameworks the PRC expects, grounded in K-12 Basic Education Curriculum (BEC) standards and DepEd policy.

Summary

Questioning, communication, and instructional materials are the three interlocking pillars of effective elementary teaching. Questioning techniques—mastering convergent versus divergent and low-level versus high-level questions, extending wait time to 3–5 seconds, and using probing, prompting, and redirecting strategically—create a thinking-focused classroom where learners feel safe to risk answers and engage deeply. Classroom communication relies on the sender-message-channel-receiver-feedback model, with attention to clarity, alignment of verbal and non-verbal signals, active listening, and reduction of physical, physiological, psychological, and semantic barriers. Instructional materials—from the chalkboard to realia to multimedia—are selected based on alignment with learning objectives and appropriateness to learners, sequenced from concrete (Dale's Cone base) to abstract (tip), and integrated purposefully with the teacher's mediation as the essential ingredient that transforms a tool into genuine instruction. All three work together: a high-level question framed clearly, supported by a well-chosen concrete material, answered honestly in a climate of psychological safety created by the teacher's respectful communication, results in deep learning. On the Licensure Examination for Teachers, you will encounter scenarios testing your ability to identify question types, recognize teaching techniques, and select and use materials wisely. Master the precise vocabulary (convergent, divergent, probing, prompting, redirecting, wait time), understand the principles (alignment, sequencing concrete-to-abstract, barrier reduction), and apply them to realistic Philippine elementary classroom contexts. These skills reflect the Code of Ethics for Professional Teachers (RA 7836)—particularly the principles of respecting learner dignity, ensuring equal opportunity, and creating an inclusive environment—and align with DepEd's commitment to quality, accessible, engaging instruction for all learners.

Sections

Questions are the teacher's chief instrument for stimulating thinking, diagnosing learner understanding, and inviting participation. Effective questions serve multiple purposes: they check prior knowledge, focus attention, review and reinforce learning, stimulate higher-order thinking, and promote active engagement. On the LET, you will encounter questions about question types and questioning strategies. Teachers classify questions along two overlapping dimensions that are often confused: convergent versus divergent (describing the range of acceptable answers) and low-level versus high-level (describing the cognitive demand). Understanding the distinction is essential for exam success and classroom practice.

1. Questioning Techniques: The Teacher's Primary Tool

Examples

A Grade 3 teacher asks: 'What is the capital of the Philippines?' This is a convergent, low-level question requiring recall of a single correct answer.
The same teacher later asks: 'If the capital of the Philippines moved to Mindanao, what changes might happen to the country?' This is a divergent, high-level question requiring analysis and prediction.
A Grade 1 teacher asks: 'Can you show me three objects in our classroom that are red?' This is convergent (objects must be red) but requires higher-level thinking because the learner must identify, analyze, and select.

Key Points

Questions are essential diagnostic and instructional tools in the classroom
Two classification systems describe questions: convergent-divergent and low-high level
These systems overlap but are not identical
Effective teachers use a balanced mix of question types
Wait time significantly improves response quality and participation

Questions differ in the range and number of acceptable answers. A **convergent question** has one correct or expected answer; it narrows thinking toward a single target. Convergent questions typically draw on recall or require students to follow a single logical path. They are valuable for checking factual understanding and building foundational knowledge. A **divergent question** is open-ended and invites many possible, equally valid answers; it expands and branches thinking. Divergent questions call for imagination, prediction, creative reasoning, or original thinking. Both question types are necessary in a balanced questioning strategy. The LET frequently presents a classroom scenario and asks you to identify whether a question is convergent or divergent based on its wording and the range of acceptable answers.

Heading

1.1 Convergent vs. Divergent Questions

Examples

Convergent: 'How many provinces are in the Philippines?' (one correct answer: 82, though this has changed over time)
Divergent: 'What would happen if the Philippines had different geography—no islands, all mountains, or desert climate?' (multiple reasonable predictions possible)
Convergent: 'Name the three main island groups of the Philippines.' (Luzon, Visayas, Mindanao)
Divergent: 'Why do you think the Philippines is called the 'Pearl of the Orient Seas'? What does this name suggest about its value?' (multiple interpretations acceptable)
Grade 2 convergent: 'What sound does the letter 'b' make?' (single correct response)
Grade 2 divergent: 'What could you do with an empty box? Tell me as many ideas as you can.' (open-ended, creative responses)

Key Points

Convergent questions narrow thinking to one expected answer
Divergent questions open thinking to many possible answers
Convergent questions build foundational knowledge; divergent questions stretch reasoning
The 'What if...?' question structure typically signals a divergent question
Both types serve different instructional purposes and should be balanced

Questions are also classified by the cognitive demand they place on learners. Using Bloom's revised taxonomy (Anderson & Krathwohl, 2001) as the framework, questions are sorted into two broad categories. **Low-level questions** require recall and simple comprehension; they tap the lower cognitive levels of Remember and Understand. These questions check whether learners can retrieve information or grasp basic meaning. **High-level questions** require deeper thinking: applying knowledge to new situations, analyzing components and relationships, evaluating evidence and arguments, or creating new ideas. They engage the higher cognitive levels of Apply, Analyze, Evaluate, and Create. Effective teaching requires balance: low-level questions build the foundation and diagnose gaps, while high-level questions push learners to think critically and construct meaning. The LET tests your ability to distinguish these levels and recognize that convergent-divergent (describing the answer range) and low-high (describing cognitive demand) are separate dimensions, though they often correlate.

Heading

1.2 Low-Level vs. High-Level Questions: Bloom's Revised Taxonomy

Examples

Low-level: 'Define photosynthesis.' (requires recall or simple understanding)
High-level: 'Compare photosynthesis in plants grown indoors under artificial light with those grown outdoors in sunlight. What differences might you observe and why?' (requires analysis and application)
Low-level: 'List the planets in our solar system.' (recall)
High-level: 'If Earth's orbit were closer to the Sun, how would this affect Earth's climate, seasons, and life?' (application and analysis)
Grade 4 low-level convergent: 'What is 7 × 8?' (one answer, simple recall)
Grade 4 high-level convergent: 'A farmer has 56 pesos to buy seeds that cost 7 pesos each. How many packets can he buy, and how much money will he have left?' (one answer, but requires problem-solving)
Grade 2 low-level divergent: 'Name different colors you see in our classroom.' (recall only, but open-ended answers)
Grade 2 high-level divergent: 'Why might people choose to paint their houses different colors? What does color choice tell us about a person?' (analysis and inference)

Key Points

Low-level questions engage Remember and Understand (Bloom's taxonomy)
High-level questions engage Apply, Analyze, Evaluate, and Create
Low-level questions check foundational knowledge; high-level questions promote critical thinking
Convergent-divergent and low-high are overlapping but distinct dimensions
A question can be convergent and high-level, or divergent and low-level (though these are less common)
Balanced instruction uses both low-level and high-level questions

**Wait time**, researched and defined by Mary Budd Rowe, refers to the silence a teacher allows at key moments during questioning. Rowe identified two critical pauses. **Wait Time I** is the pause *after* the teacher asks a question, before calling on any learner. **Wait Time II** is the pause *after* a learner gives an answer, before the teacher reacts, evaluates, or moves on. Research shows that extending each pause to approximately **three to five seconds** produces significant improvements: learners give longer and more thoughtful answers, more hands go up (increasing participation), the quality of reasoning improves, students talk to each other rather than waiting for the teacher to speak, and lower-performing learners are more likely to volunteer. The opposite habit—rushing to fill silence—is the most common mistake in Philippine classrooms. Teachers often answer their own questions or move quickly to another student, training learners to be passive. On the LET, if you see a scenario where 'the teacher waits several seconds after asking a question,' the concept is **wait time**, and the expected learning benefit is deeper, more inclusive, and more student-centered responses. This strategy also aligns with RA 7836's principle of providing equal opportunity and encouraging every learner's participation.

Heading

1.3 Wait Time: The Power of Pause

Examples

Teacher asks Grade 3: 'Why do you think the sun rises in the east?' Then waits silently for 4 seconds. A quiet learner (who might have said 'I don't know' if rushed) thinks and raises her hand. More hands go up. Answers are longer and show reasoning, not just guesses.
Teacher asks: 'What problems did the Spanish colonizers create in the Philippines?' Waits 5 seconds (no one volunteering yet). Then: 'Think about government, religion, language, economy.' Waits 3 more seconds. Now more learners have ideas to share.
Without wait time: Teacher asks → 0.5 seconds → teacher calls on Maria → Maria answers 'plants' → 0.3 seconds → teacher says 'Yes, good,' and moves on. Learning is shallow, only one voice heard.
With wait time: Teacher asks → 4 seconds of silence (visibly thinking, not filling with 'um' or tapping) → multiple hands up → Teacher calls on Ricky → Ricky gives a detailed answer → Teacher pauses 3 seconds (not repeating Ricky's answer) → Teacher asks 'Why do you think that, Ricky?' → Ricky elaborates → Teacher pauses again before redirecting to another learner.

Key Points

Wait Time I: silence after asking the question
Wait Time II: silence after a learner's response
Optimal duration: 3–5 seconds for each pause
Wait time increases response length, thoughtfulness, participation, and equity
Rushing to fill silence is the most common mistake
Wait time encourages student-to-student talk and peer learning
Extending wait time is especially important for lower-performing learners

After a learner responds to a question, skilled teachers use precise follow-up techniques. These three strategies—**probing**, **prompting**, and **redirecting**—sound similar but serve distinct purposes and the LET frequently tests the distinction. **Probing** means asking follow-up questions that push a learner to think more deeply about their own answer. Probing does not give away the answer; instead, it invites elaboration, justification, or evidence. Phrases like 'Why do you think so?' 'Can you give an example?' 'How do you know?' and 'Tell me more' are probes. **Prompting** means giving hints, cues, rephrasing, or scaffolding to help a learner who is stuck or partially correct move toward the answer. A prompt provides support without simply telling the answer. For example, if a learner struggles with 'How do plants get water?' a prompt might be 'Look at the soil around the plant. What do you see there?' Prompting is gentler than probing and acknowledges the learner's difficulty. **Redirecting** means passing the same question (or a modified version) to another learner to widen participation and give other students a chance to think. Redirecting is especially useful after one learner gives a partially correct or limited answer. It is not dismissal; it expands the conversation. All three techniques preserve learner dignity and maintain a safe, thinking-oriented classroom, as emphasized in RA 7836's principle of treating learners with respect and encouraging their active participation.

Heading

1.4 Probing, Prompting, and Redirecting: Following Up on Responses

Examples

Learner says: 'Plants need sunlight to grow.' Teacher probes: 'Why do you think plants need sunlight? What happens inside the plant when it gets sunlight?' (pushing learner to think deeper about photosynthesis)
Learner is stuck on 'What do we call the time between sunrise and sunset?' Teacher prompts: 'Think of a word that rhymes with 'day.' What is the opposite of night?' (giving scaffolding, not the answer)
Teacher asks: 'Why did the Spanish colonizers come to the Philippines?' Learner answers: 'They wanted gold.' Teacher redirects: 'Thank you. What do the rest of you think? Were there other reasons besides gold?' (spreading participation, not rejecting the first answer)
Grade 5 Socratic sequence: Teacher: 'Is this a healthy diet (showing processed snacks)?' Learner: 'No.' Teacher probes: 'Why not?' Learner: 'Has too much sugar.' Teacher probes: 'What does sugar do to our body?' Learner: 'Gives us energy.' Teacher: 'Is energy bad?' Learner: 'No, but too much...' Teacher: 'So what makes a diet healthy?' Learner realizes balance is key.
Redirecting tactfully: Learner says: 'Water pollution comes from factories.' Teacher: 'Yes, factories are one source. Who can add another source of water pollution?' (acknowledges without repeating, redirects to deepen)

Key Points

Probing: push the same learner to think deeper (Why? Can you explain? Give an example.)
Prompting: give hints or scaffolding to a stuck learner (rephrasing, cues, leading questions)
Redirecting: pass the question to another learner (widens participation)
All three preserve dignity and avoid ridicule
Probing deepens; prompting helps; redirecting spreads
Socratic questioning is a sustained series of probes leading learners to discover answers themselves
Using these techniques correctly models inquiry and critical thinking

How a teacher distributes questions across the class shapes the learning environment and ensures all learners, not just the eager few, are engaged and held accountable. Equitable questioning practice includes: (1) **asking the question first, pausing, then calling a name**—this way, every learner prepares an answer mentally, not just the one called on; (2) **calling on volunteers and non-volunteers alike**—relying only on raised hands means quiet, shy, or lower-performing learners never participate and may disengage; (3) **varying the pattern of who is called on**—avoiding predictable sequences (e.g., always left to right, always the same students) so learners remain alert; (4) **pitching questions at a level where quieter or lower-performing learners can succeed**—not always asking the hardest questions to the brightest students, but giving struggling learners a chance at lower-level or appropriately scaffolded questions; and (5) **spreading questions across gender, cultural groups, and ability levels**—conscious attention to avoid stereotyping or bias. The LET and DepEd policy both emphasize equity. RA 7836 mandates that teachers 'recognize the inherent dignity and worth of each learner' and provide equal opportunity. Poor questioning habits flagged on exams include: answering one's own question (defeating the purpose), asking multiple questions in rapid succession (confusing learners), and repeating every question or every answer verbatim (training learners to stop listening).

1.5 Distributing Questions: Equity and Participation

Examples

Poor practice: Teacher calls on Maria (hand up) immediately. Maria answers. Teacher repeats her answer, then calls on Juan. Only 2 of 40 learners are thinking. Teacher is doing much of the talking.
Better practice: Teacher poses question to the class. Waits 4 seconds (all 40 learners thinking). Calls on Rey (a quiet student). Rey hesitantly answers. Teacher probes 'Why?' Rey elaborates. Teacher says 'Thank you,' and redirects: 'What do others think?' (Many now speaking, all engaged.)
Biased practice: Teacher calls only on eager-hand-raising boys for hard questions and only on girls for 'soft' questions (reading aloud, recall). Lower-performing learners never get a chance.
Equitable practice: Teacher systematically ensures quiet learners, both genders, and learners of varying abilities get questions—pitched appropriately. A shy Grade 2 learner is asked: 'What color is the gumamela?' (easy, builds confidence). Later, the same learner is asked a higher-level question with scaffolding: 'Why do you think the flower is red? What might red mean in nature?'
Bad habit—answering own question: Teacher: 'Who knows what the water cycle is? Well, it's evaporation, condensation, and precipitation.' (No learner had to think; the teacher just lectured.)
Bad habit—multiple questions: Teacher: 'Can you tell me the three main islands of the Philippines, their capitals, and which is most populous?' (Learners freeze; too many questions at once.)
Bad habit—repeating answers: Teacher: 'What do plants need to grow?' Learner: 'Water.' Teacher: 'Yes, plants need water. What else?' (Learners learn to wait for the teacher to repeat so they can ignore the first time.)

Key Points

Ask the question to the whole class first, pause, then call a name
Call on volunteers and non-volunteers fairly
Vary the pattern to keep all learners alert
Pitch questions at levels where different learners can succeed
Avoid predictable sequences and unconscious bias
Do not answer your own question; allow wait time
Do not ask multiple questions at once; ask one clear question
Do not repeat every answer; learners should listen attentively the first time
Equitable questioning upholds RA 7836 principles and promotes inclusion

How a teacher treats—or mistreats—an answer shapes the climate for future risk-taking and critical thinking. A learner who is mocked for a wrong answer will hesitate to volunteer again. Conversely, a classroom where wrong answers are treated as learning opportunities grows thinkers. Effective response handling follows these principles: **Accept and acknowledge every honest attempt**—never ridicule, sigh, or show frustration with a wrong answer. **For a correct answer**, give specific, genuine praise or confirmation (not a vague 'Good job' but 'You correctly identified the verb and object'). **For a partially correct or wrong answer**, use probing or prompting to guide the learner toward understanding rather than simply saying 'No, that's wrong' and moving on. Preserve the learner's dignity by responding constructively, sometimes by affirming what was right ('You correctly identified that this happened during Spanish colonial times') before probing the incomplete part ('Now, can you explain why the Spanish were interested in trade?'). This approach, grounded in RA 7836's principle of treating learners with respect and RA 7610's child-protection requirements (ensuring psychological safety), creates an environment where learners feel safe to think, risk making mistakes, and engage in genuine inquiry rather than guessing what the teacher wants to hear.

1.6 Handling Learner Responses: Creating a Safe Thinking Climate

Examples

Wrong answer handled poorly: Teacher: 'What is the smallest unit of life?' Learner: 'A virus.' Teacher: 'No, that's wrong. Who else knows?' (Learner feels ashamed; won't raise hand again.)
Wrong answer handled well: Teacher: 'What is the smallest unit of life?' Learner: 'A virus.' Teacher: 'You're thinking of something very small, and viruses are indeed tiny. But viruses are not alive by themselves—they need a cell. What do you think is the smallest living thing that can exist on its own?' (Affirming the thinking, prompting toward the cell.)
Partial answer handled well: Teacher: 'Why did the Spaniards colonize the Philippines?' Learner: 'To get money.' Teacher: 'Yes, profit was a goal. Can you be more specific about what they might trade or profit from?' (Acknowledging the kernel of truth, probing for depth.)
Correct answer with specific praise: Learner correctly diagrams a sentence. Teacher: 'Excellent! You correctly identified the subject 'The child,' the verb 'ran,' and the prepositional phrase 'to school.' That shows you understand sentence structure.' (Specific feedback, not just 'Good job.')
Creating a safe climate: Grade 2 learner attempts a simple math problem and gets it wrong. Teacher says: 'I like how you tried to count by ones. Next time, let's try grouping by tens, which is faster. Show me again.' (Praising the strategy, correcting the approach, inviting another attempt.)

Key Points

Never ridicule or demean a learner's answer
Accept and acknowledge honest attempts
Give specific praise for correct answers
Probe or prompt wrong or partial answers; guide rather than dismiss
Preserve the learner's dignity by affirming what is correct before addressing gaps
Wrong answers are teaching opportunities, not failures
A safe thinking climate is essential for critical thinking and risk-taking
Handling responses with respect aligns with RA 7836 and RA 7610

Teaching is fundamentally an act of communication. The standard communication model—sender → message → channel → receiver → feedback, subject to noise—provides a framework for diagnosing breakdowns in the classroom. The **sender** (teacher or learner) encodes an idea into a **message** and transmits it through a **channel** (spoken words, gestures, written text, images) to a **receiver** (learner or teacher), who decodes and interprets it. The receiver then sends **feedback** (questions, nods, silence, confusion) that tells the sender whether the message was understood. **Noise** or barriers—anything that distorts, blocks, or interferes with the message—disrupts this flow. Effective classroom communication requires attention to several factors: clarity of language and pace matched to learners, alignment of verbal and non-verbal signals, active listening, and reduction of barriers. When a teacher's words say 'I'm proud of your effort' but the tone and facial expression convey boredom or irritation, the learner receives a **mixed message** and the non-verbal signal (usually more powerful) overrides the words. Congruent, aligned communication is the goal. On the LET and in DepEd training, classroom communication is emphasized as foundational to effective teaching and to maintaining an inclusive, trusting environment.

2. Classroom Communication Skills: The Message Model and Barriers

Examples

Clear communication: Teacher explaining fractions to Grade 4. Uses simple language ('parts of a whole'), writes visibly, draws pictures, speaks at moderate pace, pauses for questions. Learners understand.
Unclear communication: Teacher explains the same topic using abstract terms ('denominator,' 'numerator,' 'rational number') at rapid pace, without visuals, without pausing. Many learners are lost.
Mixed message: Teacher says 'I'm happy to help you with this problem' (words) while sighing, rolling eyes, and glancing at the clock (non-verbal). Learner feels dismissed, not helped.
Aligned communication: Teacher says 'I believe you can solve this' (words) with eye contact, a genuine smile, and an encouraging nod (non-verbal). Learner feels supported.
Active listening: Student: 'I don't understand why my answer is wrong.' Teacher (not interrupting): Listens fully, then paraphrases: 'So you used multiplication, but the problem asked you to divide. Is that right?' Student: 'Oh! I misread it!' Teacher: 'That happens. Let's solve it together now.' (Teacher listened, clarified, and guided, rather than defending or dismissing.)
Barriers to communication in Philippine classrooms: (1) Physical—noisy hallway, poor chalkboard visibility; (2) Physiological—hungry or tired learners; (3) Psychological—learner anxiety, teacher frustration, cultural shyness; (4) Semantic—unfamiliar words, ambiguous instructions.

Key Points

Communication model: sender → message → channel → receiver → feedback
Noise or barriers distort the message
Clarity: language, pace, and vocabulary matched to learners
Verbal-non-verbal alignment: tone, expression, gesture, posture must reinforce words
Active listening: attend fully, paraphrase, respond to what learners say
Feedback is essential; two-way communication confirms understanding
Mixed messages undermine trust and clarity
Non-verbal signals often carry more weight than words

Barriers or 'noise' in communication can be classified into four types, and recognizing them helps teachers diagnose why learners are not understanding. **Physical barriers** include environmental factors: poor room acoustics, background noise, inadequate lighting or board visibility, crowded seating, or equipment malfunction. **Physiological barriers** relate to the sender's or receiver's physical state: a hungry learner cannot concentrate, a tired teacher's voice is flat, illness or fatigue affects attention. **Psychological barriers** involve emotions and mental state: a learner anxious about 'being called on' may shut down; a teacher's frustration or impatience colors the tone; cultural expectations (e.g., hesitation to speak up in some contexts) or low confidence limit participation. **Semantic barriers** arise from language: using unfamiliar vocabulary, ambiguous instructions, idioms not understood by English learners, or cultural references unknown to learners. DepEd policy emphasizes that teachers must create **inclusive, barrier-reducing environments**. This means teachers should speak clearly and avoid jargon, repeat important ideas in different ways, scan the room to ensure all can see and hear, manage class noise, acknowledge cultural and linguistic diversity, and monitor for signs of confusion or disengagement. On the LET, if you encounter a scenario where learners are not responding, ask: What barrier might be in play? A teacher who recognizes a barrier can act: 'I see some of you can't see the board; let's move to the front corner.' 'You look tired; let's take a stretch break.' 'This word is new; let me explain it another way.'

Heading

2.1 Barriers to Communication: Recognizing and Reducing Noise

Examples

Physical barrier: Class is near the noisy hallway. Solution: Move to a quieter corner, close the door, or use a raised voice with clear articulation.
Physiological barrier: Many Grade 1 learners are sleepy after lunch. Solution: Engage them with movement, music, or a more interactive activity; avoid lecturing.
Psychological barrier: Learners from a culture valuing group harmony are reluctant to speak individually. Solution: Offer pair-share or group discussion before whole-class participation.
Semantic barrier: Teacher says 'Triangulate the coordinates on the Cartesian plane.' Learners look blank. Solution: 'Find the point where these two lines meet on our graph. Let's do an example on the board first.'
Teacher notices: Learners keep asking 'Can you repeat that?' Solution: Recognizing a physical or semantic barrier, teacher repeats using simpler words, writes it on the board, or uses a visual example.
Teacher notices: One learner always avoids eye contact and doesn't volunteer. Solution: Offering private encouragement ('You have good ideas; would you like to share?') and creating a safer space reduces psychological barriers.

Key Points

Physical barriers: environment (noise, light, space, equipment)
Physiological barriers: hunger, fatigue, illness, physical state
Psychological barriers: anxiety, frustration, low confidence, cultural shyness
Semantic barriers: unfamiliar words, ambiguous instructions, cultural references
Teachers must actively identify and reduce barriers
Creating an inclusive environment reduces barriers to communication
Recognizing barriers is the first step to removing them

**Instructional materials** (also called teaching aids, learning resources, or visual aids) are the objects, images, and media a teacher uses to make abstract content concrete, support learning objectives, and engage learners. Examples range from the chalkboard and real objects (realia) to photographs, models, printed charts, audio recordings, videos, and interactive digital resources. Well-chosen and skillfully used materials: (1) gain and hold attention, (2) make abstract ideas tangible and visible, (3) address diverse learning preferences (some learners are visual, others kinesthetic), (4) save explanation time by showing rather than only telling, and (5) improve retention because learners combine verbal and visual information. However, **materials never teach by themselves**; they are only tools. The teacher's mediation—how the teacher introduces, guides attention to, and facilitates discussion around the material—is what makes an aid *instructional*. A flashy video that does not connect to the lesson objective or learner prior knowledge is a distraction, not a teaching tool. On the LET, questions about instructional materials test your ability to select materials based on clear criteria, understand Dale's Cone of Experience (and how to apply it, not memorize percentages), and recognize best practices for using materials in the classroom. The DepEd K-12 Curriculum emphasizes that all learners deserve quality resources, and teachers are expected to improvise and adapt when resources are scarce—a reality in many Philippine schools.

Heading

3. Instructional Materials: Selection, Development, and Use

Examples

Effective use: A Grade 3 teacher introducing 'symmetry' brings real butterflies (or photos) and cut-out butterfly shapes. Learners fold and explore. Then uses a diagram. Then a PowerPoint. Moves from concrete to abstract.
Poor use: A Grade 3 teacher plays a 10-minute nature documentary on insects. Learners are entertained but the connection to the lesson objective (identifying symmetry) is never made. The video is a distraction.
Improvisation in a resource-scarce setting: A Grade 2 teacher has no globe. She uses a ball painted with markers to show continents and oceans. Learners understand continents just as well.
Technology backup: A Grade 5 teacher plans to show a video on the water cycle. The projector breaks. She has a backup: a large printed poster and a glass of water to demonstrate evaporation by placing it in sunlight.

Key Points

Instructional materials make abstract content concrete and engaging
Materials support but do not replace teaching; the teacher's mediation is essential
Materials serve multiple purposes: attention, clarity, accessibility, retention
Selection must be deliberate, based on clear criteria
The most important criterion is alignment with learning objectives and learner needs
Dale's Cone of Experience guides the progression from concrete to abstract experiences
Materials should be simple, clear, large, purposefully integrated, and checked beforehand
Teachers must manage technology failures and have backup plans

Materials are not grabbed on impulse; they are chosen deliberately against clear criteria. The **most critical criterion is alignment with the lesson objective and appropriateness to the learners**. A beautiful poster of the solar system is not a good choice for a lesson on weather unless the weather is linked to solar radiation. The following criteria guide selection: (1) **Alignment with objectives** — does the material directly support the intended learning outcome? (2) **Appropriateness to learners** — is it suited to their age, ability, prior knowledge, cultural background, and learning preferences? (3) **Accuracy and currency** — is the content correct and up-to-date? (An old textbook with outdated information is unreliable.) (4) **Clarity and quality** — is the material legible, audible, or clearly visible? Is it free of clutter and confusing details? (5) **Practicality** — is it available and affordable? Is it safe? Can the teacher manage it in this classroom? (6) **Interest and motivation** — does it engage learners without becoming the distraction rather than the support? A material that ticks all boxes but misses the objective is still a poor choice. The LET frequently presents a scenario and asks which material is *best* for a specific lesson and grade level. Always check objective alignment and learner appropriateness first.

Heading

3.1 Criteria for Selecting Instructional Materials

Examples

Alignment test: Lesson objective: 'Identify the parts of a flower.' A real flower (realia) → aligns perfectly. A video on pollination → useful but less direct. A song about flowers → off-target. The real flower wins.
Appropriateness to learners: For Grade 1 (ages 6–7), a real, large, bright flower (gumamela or sampaguita) is ideal—concrete, safe, engaging. For Grade 6 (ages 11–12), a labeled diagram with scientific names is appropriate and respected by older learners. Different materials suit different ages.
Accuracy test: An old textbook showing 9 planets is inaccurate (Pluto was reclassified). A current resource showing 8 planets is accurate and must be used.
Clarity: A chart showing Philippines' exports is good. A chart with 50 product names in tiny font, overlapping lines, and no legend is not clear. Choose the clean chart.
Practicality: A teacher wants to show a video on the water cycle but the school has no internet and the projector is broken. Improvise: draw a large, colorful diagram on paper or use a simple experiment (water in a bag left in the sun) to demonstrate.
Interest: A video game about fractions is fun, but if the game is loosely connected to the lesson and learners spend time on non-learning activities, it is not the best choice. A well-designed game aligned to the objective is better.

Key Points

Alignment with objective is the first and most important criterion
Appropriateness to learner age, ability, and background is essential
Accuracy and currency ensure correct content
Clarity and quality make the material usable
Practicality ensures feasibility in the actual classroom setting
Interest supports but should not overshadow learning purpose
All criteria together guide wise selection
When resources are scarce, improvisation using local materials is acceptable if it meets criteria

Edgar Dale's **Cone of Experience**, published in 1946, is a classic framework that arranges learning experiences along a spectrum from most concrete (at the base) to most abstract (at the tip). The cone, from bottom to top, includes: **direct purposeful (hands-on) experiences** (doing, exploring, experimenting), **contrived experiences** (models, mock-ups, simulations), **dramatized experiences** (skits, role-plays), **demonstrations**, **study trips** (field trips), **exhibits**, **motion pictures and recordings** (videos, audio), **still pictures and radio** (photographs, illustrations), **visual symbols** (maps, diagrams, charts), and **verbal symbols** (words, text). The key **application** for teaching is the **design principle**: the progression from concrete to abstract guides how to structure a lesson. The **base** (direct, hands-on experience) is most suitable for **young learners, beginning learners, or unfamiliar content**. The **tip** (abstract words and symbols) suits **older, experienced learners** who already have concepts in mind to attach words to. Teachers should **start concrete and move toward abstract** as learners develop understanding. A frequent **LET pitfall** is confusing Dale's Cone with the fabricated 'Cone of Retention' that claims 'people remember 10% of what they read, 90% of what they do.' This is **NOT Dale's work**; it is a myth. Dale's Cone is about the *type* of experience, not fixed retention percentages. Do not use percentages when discussing Dale's Cone.

3.2 Dale's Cone of Experience: From Concrete to Abstract

Examples

Concrete to abstract in a Grade 1 lesson on parts of a plant: (1) Children dig up a real plant and observe roots, stem, leaves. (2) Teacher shows a photo of a plant with parts labeled. (3) Children draw and label a plant diagram. (4) Teacher writes and repeats: 'Roots, stem, leaves, flower, fruit.' Learners have moved from concrete (real plant) to abstract (words) with understanding at each step.
Concrete to abstract in a Grade 4 lesson on fractions: (1) Children share real pizza or bread (direct experience of half, quarter). (2) Teacher shows a picture of a pizza divided. (3) Children draw fractional diagrams. (4) Teacher writes 1/2, 1/4 on the board. Concrete first, abstract later.
Skipping concrete—a mistake: A Grade 2 teacher defines 'erosion' using only words: 'Erosion is the wearing away of soil.' Learners are confused. Better: Teacher brings a small pile of soil, water, and a tilted board. Pours water and shows soil washing away. Now 'erosion' makes sense. Learners then understand the word.
Using Dale's Cone in a resource-limited setting: A teacher with no real specimens uses a model (contrived experience) instead of a direct experience—acceptable because it is still concrete. A diagram is better than words alone. Progression matters even with limited resources.
Field trip (study trip, middle of the cone): A Grade 3 class visits a local garden or farm. They see plants growing. Later, they discuss and draw what they saw. Later still, they read about agriculture. Starting with the concrete field trip anchors all abstract learning that follows.

Key Points

Dale's Cone ranges from concrete (direct experience) at base to abstract (symbols) at tip
The design principle: start concrete, move toward abstract
Concrete experiences suit young, beginning, or new-to-topic learners
Abstract symbols suit older, experienced learners with prior concepts
The Cone guides selection of materials and sequencing of instruction
Dale's Cone is NOT about retention percentages (that is a myth)
Real objects and hands-on activities are at the concrete base
Words and text alone are at the abstract tip
Effective lessons often use multiple levels: real object → picture → diagram → word

Common types of instructional materials used in elementary classrooms include: **Board work** (chalkboard, whiteboard, smartboard), **Realia** (real objects), **Models and mock-ups**, **Printed materials** (charts, pictures, worksheets, textbooks), and **Multimedia** (slides, audio, video, digital interactive resources). Each type has strengths and best practices. **Board work** is the most universally available aid. Write legibly and large enough for the back of the room to see. Organize information in a clear layout, not scattered or overlapping. Use the board while facing learners as much as possible (do not turn your back for long). Erase irrelevant material so the board does not become cluttered. Use color and simple sketches to aid memory. **Realia** (real objects) is the most concrete and sensory-rich. A real flower, coin, tool, or food is incomparably more engaging and clear than a picture for young learners meeting the concept for the first time. When the real thing is impractical, unsafe, or unavailable, a **model or mock-up** (scale model of a volcano, model skeleton, toy car) substitutes. **Printed materials** are accessible but can be abstract; they are best paired with realia or demonstration. **Multimedia and projected media** (videos, images, animations) are powerful for showing motion, processes, and distant or microscopic realities. They capture attention and show sequences (e.g., a plant growing over weeks in a time-lapse video). However, they must be **integrated purposefully**, not used as a break from teaching. A video should connect clearly to the objective, be the right length (often shorter than you think; 5–10 minutes for primary grades, 10–15 for upper elementary), and be followed by discussion or activity. **Principles of preparation and use apply to all materials**: (1) Keep visuals **simple and uncluttered**—one main idea per visual; avoid busy, confusing designs. (2) Make materials **large and clear enough** for all learners to see or hear. (3) **Integrate purposefully** into the lesson; use materials at the moment they support the learning, not as an afterthought. (4) **Check equipment beforehand**; test video, projector, audio. (5) **Guide learners' attention**; point to and explain what matters on a visual; do not assume they know where to look. (6) **Display only while in use**; remove materials when the lesson moves on so they do not distract. (7) **Always have a backup plan** in case technology fails. (8) **Never let a material replace teaching**; the teacher's explanation, interaction, and facilitation remain central. The DepEd value that materials support all learners—including those with visual, auditory, and kinesthetic preferences—is reflected in the recommendation to use a **mix of material types**.

3.3 Types of Materials and Principles of Preparation and Use

Examples

Board work done well: Teacher writes a clear, organized outline of the lesson: 'Parts of a Plant: 1. Roots (collect water) 2. Stem (hold plant up) 3. Leaves (make food).' Draws small sketches. Speaks while writing. Learners understand the structure.
Board work done poorly: Teacher scribbles small, overlapping words all over the board. Talks while facing the board, back to learners. Board is never erased; old work mixes with new. Learners copy messy notes and miss the point.
Realia used well: Grade 2 lesson on parts of a plant. Teacher brings a real gumamela flower (or sampaguita) for each group. Learners touch petals, smell, examine. Then see a labeled diagram. Learners understand 'petal,' 'sepal,' 'stamen' by direct contact first.
Model used well: A volcano lesson. Teacher cannot bring a real volcano. Shows a model volcano, explains with the model, then does a safe demonstration (baking soda and vinegar eruption). Learners understand the concept.
Video used well: Grade 4 lesson on the water cycle. Teacher shows a 5-minute animation of evaporation, condensation, precipitation. Stops and discusses: 'What do you see? How is water moving?' Connects to learners' experience (puddles disappearing). Plans a follow-up experiment (water in a sealed bag in sunlight) to make it real.
Video used poorly: Teacher plays a 20-minute nature documentary. Learners watch passively. No introduction, no pausing, no discussion. The connection to the lesson objective is unclear. It is entertainment, not instruction.
Integration: A lesson on community helpers. Teacher introduces the concept verbally. Shows pictures of a doctor, teacher, farmer. Learners discuss what each does. Then a guest (a local nurse or farmer) visits to tell their story. Mixed materials and direct experience make the lesson rich.
Backup plan: Teacher plans to show a video on the water cycle. The projector is broken. Backup: Uses a large printed poster and conducts the sealed-bag experiment (placing a glass of water in sunlight to show evaporation). The learning objective is met without the video.
Guiding attention: Teacher displays a chart of the Philippines' regions. Does not assume learners know where to look. Points: 'Here is Luzon. Here is Visayas. Here is Mindanao.' Labels each. Discusses: 'What do you notice?' Learners' attention is guided to the key information.
Simple vs. cluttered: A chart on 'Healthy Foods' with 5 clear categories (grains, vegetables, protein, dairy, fruit), each with a picture and one color, is clear. A chart with 50 food pictures, no categories, tiny fonts, and clashing colors is confusing. The simple chart teaches; the cluttered one distracts.

Key Points

Board work: legible, organized, face learners while writing, erase clutter, use color and sketches
Realia: most concrete and engaging; use when safe and available
Models: substitute when realia is impractical or unsafe
Printed materials: useful but benefit from being paired with realia or demonstration
Multimedia: powerful for motion and process, must be integrated purposefully and checked beforehand
Keep visuals simple, uncluttered, and large
Integrate materials purposefully at the moment they support learning
Guide learners' attention; point to key elements
Display only during use; remove to avoid distraction
Have backup plans for technology failure
The teacher's mediation is what makes a material instructional
Mix material types to reach diverse learners

Questioning, communication, and instructional materials are not three separate topics; they are interdependent tools that work together in effective teaching. A skillfully asked question (high-level, divergent, probed) invites learners to think and speak, exercising **communication**. A carefully chosen material (aligned to the objective, concrete for young learners, integrated purposefully) **supports the question and the discussion** that follows. A teacher's clear, congruent communication—aligned words and tone, active listening, feedback—**creates the trust** in which learners are willing to risk wrong answers. On the LET, you may encounter scenarios that test all three. For example: 'A Grade 3 teacher shows pictures of different habitats (material). She asks: "What animals might live in the forest? Why?" (high-level, divergent question). A learner says: "Tigers." The teacher probes: "Why would tigers live in a forest and not a desert?" (probing, communication). Another learner adds: "There's more food and water in the forest." The teacher listens actively and confirms: "Exactly—forests have the resources animals need." (Affirming, communicating respect.) The teacher might then redirect: "What do you think, Marco? What animals live in other habitats?" (Redistributing questions, ensuring all think.) This integrated scenario showcases questioning (high-level probing), communication (clarity, active listening, respect), and materials (pictures as visual support).' Mastery of all three, applied together, is the hallmark of effective elementary teaching and what the LET expects.

4. Integrating Questioning, Communication, and Materials: The Complete Picture

Examples

Integrated scenario 1: Lesson on community workers. Teacher displays pictures (material: visual support). Asks: 'What does a barangay captain do? Why is this job important for our community?' (high-level, divergent questions). Learner answers hesitantly. Teacher probes with a prompt: 'Think about problems in our barangay. Who helps solve them?' (Scaffolding communication). Learner elaborates. Teacher affirms: 'Great thinking!' (Respect in communication). Other learners raise hands, now confident to contribute. Materials, questions, and communication work in sync.
Integrated scenario 2: Lesson on plant growth. Teacher brings real seeds and small pots (realia: concrete material). Asks: 'What does a seed need to grow? How do you think we can test this?' (High-level, divergent). Learners brainstorm (communication, participation). Teacher guides with prompts: 'Think about water, light, soil. Which one is most important? Why?' (Questioning and communication together). Learners design a simple experiment. The material (real seeds) makes the question real; the questioning deepens thinking about the material.
Integrated scenario 3: Lesson on shapes. Teacher shows a colorful shape chart (material). Asks: 'Can you find all the triangles?' (Low-level convergent, checks understanding). Then: 'Why do you think a triangle is useful for a roof? Where else do you see triangles?' (High-level, divergent, real-world connection). A learner struggles. Teacher uses a visual prompt: Points to the roof-shaped part of the chart. Learner understands. Teacher redirects to another learner: 'What do you see?' (Spreading participation.) All three elements—material, question type, and responsive communication—support learning.

Key Points

Questioning, communication, and materials work together, not in isolation
A good question prompts thinking and speaking
Clear communication builds the trust in which learners risk answers
Well-chosen materials support and clarify questions and discussion
The teacher's mediation and interactivity tie all three together
LET scenarios often integrate all three, testing holistic teaching competence
Effective elementary teaching is the skillful interplay of question, response, material, and feedback

On the Licensure Examination for Teachers (LET), questions about this chapter typically present a short classroom scenario and ask you to identify or evaluate a teaching practice. Here are the most common formats and how to approach them: **(1) Identify the question type:** 'A teacher asks: "How many provinces are there in the Philippines?" This is a ___ question.' You must recognize: convergent (one answer), low-level (recall). Another asks: 'A teacher asks: "Why do you think the Spanish colonizers chose to settle in Luzon first?"' This is: divergent (many possible answers), high-level (analysis and inference). **Tip:** Convergent-divergent describes the *range and number* of acceptable answers. Low-high describes the *cognitive level*. They are related but distinct. **(2) Identify the technique:** 'After a learner says something incomplete, the teacher asks: "Can you tell me more? Give an example."' This is ___ .' You recognize: probing (pushing the learner to deepen their own thinking). If the scenario says the teacher 'gives a hint,' it is prompting. If the teacher 'asks the question to another student,' it is redirecting. **Tip:** Probe (deepen the same learner), Prompt (help a stuck learner), Redirect (spread participation). **(3) Wait time:** 'A teacher asks a question and ___ seconds before calling on a student.' Or: 'After a learner responds, the teacher pauses ___ seconds before reacting.' The answer is usually 3–5 seconds. **Tip:** Research (Rowe) shows that extending wait time improves response quality and participation. Rushing is the common mistake. **(4) Handling responses:** 'A learner gives a wrong answer. The teacher should:' Options might include (A) Laugh and move on (wrong; violates respect), (B) Say 'No, that's wrong' (wrong; not constructive), (C) Probe or prompt the learner (correct; guides without ridiculing), (D) Repeat the answer loudly (wrong; trains passivity). **Tip:** Wrong answers are learning opportunities. Preserve dignity by probing or prompting. **(5) Communication barriers:** 'Learners are not responding to the teacher's question. Which might be a barrier?' Answers could include (A) Physical (noise, visibility), (B) Psychological (anxiety, shyness), (C) Semantic (unfamiliar words), (D) Physiological (hunger, fatigue). All are possible barriers; look for the scenario clues. **Tip:** Barriers are real obstacles to understanding, not excuses. **(6) Material selection:** 'A teacher wants to teach about the parts of a flower to Grade 1. Which material is best?' (A) A scientific diagram with labels, (B) A real flower, (C) A video about pollination, (D) A textbook description. The answer is (B): realia, concrete, age-appropriate, direct sensory experience. **Tip:** Check alignment with objective and appropriateness to learner age/ability. For young or beginning learners, start with concrete (realia or models), not abstract (diagrams, words). **(7) Dale's Cone:** 'According to Dale's Cone of Experience, which moves from concrete to abstract?' The correct progression is: direct experience → models → pictures → words (bottom to top of the cone). **Tip:** Do NOT mention retention percentages; that is a fabrication. Focus on the principle: teach concrete to abstract. **(8) Common pitfalls to avoid in answering:** (a) Confusing convergent-divergent with low-high; (b) Calling probing 'prompting' or vice versa; (c) Thinking wait time means 10+ seconds (3–5 is optimal); (d) Choosing a flashy material that is not aligned to the objective; (e) Attaching percentages to Dale's Cone; (f) Thinking wrong answers should be dismissed rather than probed; (g) Overlooking non-verbal communication or mixed messages; (h) Selecting abstract materials (words, diagrams) for young learners' first encounter with a topic. Review the definitions in this chapter carefully and practice with sample LET questions.

5. LET-Specific Test Tips: Common Question Formats and Pitfalls

Examples

LET sample 1: 'A Grade 2 teacher asks: "What shapes do you see in our classroom?" Students respond with different shapes (door is rectangular, clock is round, etc.). This question is: (A) Convergent and high-level (B) Divergent and low-level (C) Convergent and low-level (D) Divergent and high-level.' Answer: (B) Divergent (many shapes are acceptable answers) and low-level (requires recognition only, not deep thinking). Learners identify shapes they see.
LET sample 2: 'After a learner answers a question, the teacher remains silent for 4 seconds, then asks another learner the same question. This technique is: (A) Probing (B) Prompting (C) Redirecting (D) Wait time.' Answer: (C) Redirecting. The teacher is passing the question to another learner to spread participation. (If the teacher had asked the first learner deeper questions, it would be probing; if hints were given, prompting.)
LET sample 3: 'A Grade 4 teacher wants to introduce the concept of erosion. Which sequence is best according to Dale's Cone? (A) Define erosion, show a diagram, do an experiment (B) Do an experiment (water washing soil), discuss, then define (C) Show a video, read a passage, label a diagram (D) Ask learners to memorize the definition.' Answer: (B) Concrete (experiment) before abstract (definition). Learners experience erosion, then attach the word to it.
LET sample 4: 'A learner says: "The water cycle is when water moves around." The teacher should: (A) Say "Wrong" and move on (B) Ask "Can you be more specific? Where does water move? How?" (C) Repeat the answer word-for-word (D) Ask another student.' Answer: (B). The teacher probes the learner to clarify and deepen, respecting the initial attempt but pushing for precision.
LET sample 5: 'Learners in a noisy hallway classroom are not responding to questions. Which barrier is most likely at play? (A) Semantic (B) Psychological (C) Physical (D) Physiological.' Answer: (C) Physical. Noise is an environmental, physical barrier. The teacher should move to a quieter space or speak louder and more clearly.

Key Points

LET scenarios test identification of question types, techniques, and best practices
Convergent-divergent = range of answers; low-high = cognitive level
Probe, prompt, redirect are distinct; learn their precise meanings
Wait time I (after question), Wait Time II (after response): 3–5 seconds each
Wrong answers are teaching opportunities; probe or prompt, never ridicule
Barriers are real; recognize and reduce them
For material selection, check alignment with objective and learner appropriateness
Dale's Cone: concrete at base, abstract at tip; no percentages
Mixed messages undermine trust; align verbal and non-verbal communication
Young or new learners need concrete materials and experiences first
