LET Secondary Educational Technology — Foundations of Educational Technology and Instructional MediaRevision Notes

Exam Tips

• When an LET item mentions 'systematic' or 'scientific approach to the teaching-learning process,' the answer is almost always 'technology OF education.'
• When an item mentions 'the entire educational enterprise including administration,' the answer is 'technology IN education.'
• Remember the subset rule: Instructional Technology ⊂ Educational Technology. All instructional technology is educational technology, but not all educational technology is instructional.
• Any item asking about the PRIMARY purpose or guiding principle of educational technology should be answered with 'to achieve learning outcomes' or 'technology as a means, not an end.'

Key Points

• Educational technology is NOT just about machines or gadgets — it is a systematic approach to designing, implementing, and evaluating the teaching-learning process.
• Four closely related terms are repeatedly tested on the LET: 'technology in education,' 'technology of education,' 'educational technology,' and 'instructional technology.' Keep each pair distinct.
• Technology in education = the BROAD application of technology to the entire educational enterprise, including administration, record-keeping, and communication — not only instruction.
• Technology of education = the SYSTEMATIC, SCIENTIFIC approach to the whole teaching-learning process. It is a way of thinking and designing instruction, not just equipment.
• Educational technology = use of technology (tools and processes) to support the whole field of education. This is the broader umbrella term.
• Instructional technology = a SUBSET of educational technology that focuses specifically on the teaching-learning act (instruction). Every instructional technology is educational technology, but NOT the reverse.
• Technology has two faces: HARDWARE (physical devices: computers, projectors, TV sets) and PROCESS/SYSTEM (the systematic method of designing, using, and evaluating learning). The LET favors the PROCESS view.
• The central principle: technology is a MEANS, not an END. The learning outcome always comes first; the tool is chosen to serve that outcome.
• Technology should be INTEGRATED into instruction, not simply 'added on' as decoration or novelty.

Core Concepts and Key Definitions

Common Mistakes

• Thinking 'educational technology' and 'instructional technology' are identical — instructional technology is the SUBSET focused only on instruction.
• Confusing 'technology in education' (broad application to whole enterprise) with 'technology of education' (scientific/systematic approach to teaching-learning).
• Believing that simply using a projector or computer in class constitutes good educational technology practice — the process and purposefulness matter more than the device.
• Treating technology as the goal of a lesson rather than as a tool to achieve the learning objective.

Exam Tips

• Memorize the three roles with one concrete Philippine example each: TUTOR = Mathayos drill app; TOOL = MS Word for a pupil's essay; TUTEE = pupils coding in Scratch to make a sprite move.
• If an LET scenario says 'pupils write a program' or 'pupils code,' the answer is TUTEE.
• If the item says 'the software gives feedback and corrects the pupil,' the answer is TUTOR.
• If the item says 'the pupil uses the computer to type, research, or create,' the answer is TOOL.

Key Points

• Technology serves FIVE main roles in learning: delivery and presentation, motivation and engagement, individualization, access and equity, and interaction and productivity.
• Robert Taylor's 'Tutor, Tool, Tutee' framework is a classic LET item. Know all three roles and their distinct meanings.
• TUTOR role: the computer (or technology) TEACHES the learner — drill-and-practice software, tutorials, interactive lessons where the program instructs.
• TOOL role: the learner USES the computer as an instrument — word processing a report, using spreadsheets, conducting internet research, creating a presentation.
• TUTEE role: the learner TEACHES the computer — writing programs, coding, giving the machine instructions. The learner is in charge and learns by programming or instructing the technology.
• In the TUTEE role, the deepest learning occurs because the learner must understand the content well enough to 'teach' it to the machine.
• Two guiding principles the LET always rewards: (1) Technology should be INTEGRATED, not added on; (2) Technology is a MEANS, not an END.

Roles and Functions of Technology in Learning

Common Mistakes

• Confusing TUTOR and TOOL: if the computer is teaching the pupil (drill, tutorial), it is TUTOR. If the pupil is using it to create or research, it is TOOL.
• Thinking the TUTEE role means the computer tutors two learners — it means the LEARNER is the 'tutor' of the computer by programming it.
• Forgetting that technology can serve all three roles — the same device (tablet) can be tutor, tool, or tutee depending on how it is used.

Exam Tips

• Memorize the 11 bands from base to apex using this phrase: 'Directly Contrived Drama, Demonstrates Study-Exhibits, TV-Movies-Still-Pics, Visual-Verbal.' Practice writing them out.
• Classify any scenario by asking three questions: (1) Is the learner DOING or just watching? (2) Is it REAL or a substitute? (3) Is the medium PICTORIAL or SYMBOLIC?
• The word 'direct' in the question almost always signals the BASE of the Cone (direct purposeful experiences).
• If an LET scenario says 'the teacher showed a chart' or 'the pupil read a diagram,' think VISUAL SYMBOLS (band 10).
• If the scenario says 'pupils read a textbook definition' or 'the teacher explained verbally,' think VERBAL SYMBOLS (band 11, apex).
• The Bruner connection is tested: Enactive = doing (base), Iconic = seeing (middle), Symbolic = abstract (top). Know which Cone bands fall in each zone.
• If asked whether the retention percentages are part of Dale's Cone, the answer is NO — they are a misattribution.

Key Points

• Dale's Cone of Experience by Edgar Dale is the SINGLE MOST TESTED item in Educational Technology on the LET. Know it cold.
• The Cone arranges learning experiences from MOST CONCRETE at the BASE to MOST ABSTRACT at the APEX (top).
• The Cone is NOT a hierarchy of difficulty, and it does NOT claim that one level is always better. It shows that learning is most effective when it moves from concrete experience toward abstraction.
• The BASE (most concrete, Level 1) = DIRECT, PURPOSEFUL EXPERIENCES — real, hands-on doing with actual objects and situations.
• The APEX (most abstract, Level 11) = VERBAL SYMBOLS — spoken and written words, the most abstract form of communication.
• The ELEVEN bands of the Cone, from base to apex: (1) Direct Purposeful Experiences, (2) Contrived Experiences, (3) Dramatized Experiences, (4) Demonstrations, (5) Study Trips, (6) Exhibits, (7) Educational Television, (8) Motion Pictures, (9) Still Pictures/Recordings/Radio, (10) Visual Symbols, (11) Verbal Symbols.
• The three broad zones of the Cone align with Jerome Bruner's modes of representation: ENACTIVE (doing) at the base, ICONIC (observing) in the middle, SYMBOLIC (abstracting) at the top.
• ENACTIVE zone (doing) includes: Direct Purposeful, Contrived, and Dramatized Experiences (bands 1–3).
• ICONIC zone (observing) includes: Demonstrations, Study Trips, Exhibits, Educational Television, Motion Pictures, Still Pictures/Recordings/Radio (bands 4–9).
• SYMBOLIC zone (abstracting) includes: Visual Symbols and Verbal Symbols (bands 10–11).
• Effective teaching moves from CONCRETE to ABSTRACT — begin near the base of the Cone, then work upward. This is called the 'concrete-to-abstract principle.'
• CRITICAL: The retention-percentage figures often attached to the Cone (e.g., 'we remember 10% of what we read, 90% of what we do') are a MISATTRIBUTION — they were NOT stated by Dale. The LET may test this directly.
• Always classify a given experience by asking: Is the learner DOING, OBSERVING, or SYMBOLIZING?

Dale's Cone of Experience

Common Mistakes

• Reversing the Cone — many students mistakenly place verbal symbols at the base and direct experience at the top. REMEMBER: concrete is at the BASE, abstract is at the APEX.
• Confusing 'direct purposeful experience' and 'contrived experience': if the learner works with the REAL thing, it is direct purposeful; if it is a MODEL or SIMULATION, it is contrived.
• Confusing 'contrived' (learner interacts with a model/simulation) and 'dramatized' (learner acts out a role in an event).
• Confusing 'demonstration' and 'direct experience': in a demonstration, the learner WATCHES; in direct experience, the learner PERFORMS the task themselves.
• Believing the retention-percentage figures (10% reading, 90% doing) are part of Dale's original Cone — they are NOT. They are a misattribution.
• Thinking the Cone prescribes that teachers must ALWAYS start at the base — the Cone is descriptive (showing a continuum), not a rigid prescription. However, the pedagogical principle of concrete-to-abstract DOES apply.
• Placing 'study trips' above 'exhibits' in the wrong order — the correct order is: demonstrations → study trips → exhibits → educational television → motion pictures.

Exam Tips

• For the REALIA-MODEL-MOCK-UP triad: Real thing = Realia; 3D representation = Model; Working training arrangement = Mock-up.
• The LET often gives a scenario like 'Teacher brings actual Philippine coins' → Realia. 'Teacher brings a globe' → Model. 'Teacher uses a CPR manikin' → Mock-up.
• When classifying projected vs. non-projected, ask: 'Does it need a machine to project it onto a screen?' YES = projected; NO = non-projected.
• Charts, maps, graphs, and chalkboard work are always NON-PROJECTED, even if they look sophisticated.
• Connect media classification to Dale's Cone: Realia = direct purposeful (base); models and mock-ups = contrived experience; charts = visual symbols; textbooks = verbal symbols.

Key Points

• Instructional media are the channels or materials that carry the instructional message from teacher to learner.
• Two major classification schemes appear on the LET: (1) by PROJECTION (projected vs. non-projected) and (2) by SENSORY CHANNEL (visual, audio, audio-visual).
• NON-PROJECTED MEDIA: materials used WITHOUT a projector. Examples: real objects (realia), models, mock-ups, printed text, charts, graphs, maps, chalkboard/whiteboard, flip charts, dioramas.
• PROJECTED MEDIA: materials shown THROUGH a projector or screen. Examples: slides, overhead transparencies, opaque projections, LCD/data projector output, films.
• By SENSORY CHANNEL: VISUAL media (still pictures, charts, silent film), AUDIO media (radio, recordings, podcasts), AUDIO-VISUAL media (video, television, multimedia — engaging both sight and hearing simultaneously).
• Three look-alike terms that the LET loves to test: REALIA, MODEL, and MOCK-UP. Know the exact difference.
• REALIA = the REAL OBJECT itself brought into the classroom (e.g., actual Philippine coins for a money lesson, real leaves for plant classification in Science).
• MODEL = a recognizable THREE-DIMENSIONAL REPRESENTATION of the real thing, often scaled up or down (e.g., a globe representing the Earth, a human torso model showing internal organs).
• MOCK-UP = a WORKING or SIMPLIFIED ARRANGEMENT built for training purposes, which may exaggerate, simplify, or strip away parts so a process can be practiced (e.g., a CPR manikin, a driving simulator panel).
• The CHALKBOARD/WHITEBOARD is non-projected and remains the most widely used visual aid in Philippine classrooms. Proper use: write legibly and large enough, talk TO the class not to the board, erase only after pupils finish copying.
• BULLETIN BOARDS (display boards) should be PURPOSEFUL and aligned to current lessons — not mere room decoration. A bulletin board aligned to the week's lesson serves the curriculum actively.
• The most important rule: always choose media based on OBJECTIVES first, then learners, then medium — not based on what is most expensive or most novel.

Classifying Instructional Media

Common Mistakes

• Confusing REALIA, MODEL, and MOCK-UP: a real mango is realia; a plastic mango is a model; a training arrangement that simulates making something is a mock-up.
• Classifying the chalkboard as 'projected media' — it is NON-PROJECTED.
• Thinking that more expensive or more technological media are always better — the best medium is the one that FITS THE OBJECTIVE.
• Forgetting that a bulletin board is instructional media — it must be purposeful and aligned to the lesson, not just decorative.
• Confusing 'audio-visual' (both channels at once) with simply showing something visual — audio-visual requires BOTH sight and sound simultaneously.

Exam Tips

• If an LET item asks 'what is the MOST IMPORTANT criterion in selecting instructional media,' the answer is ALIGNMENT WITH LEARNING OBJECTIVES.
• If a scenario says 'Teacher A chose a flashy animation that excited pupils but did not match the day's lesson,' the violated criterion is ALIGNMENT WITH OBJECTIVES.
• Remember the sequence: Objectives → Learners → Medium. This sequence is tested directly.
• Connect this to RA 7836 and the Code of Ethics: professional teachers are expected to use their professional judgment in selecting appropriate materials for their specific class — not just follow convenience.

Key Points

• Media selection is a DELIBERATE, PROFESSIONAL DECISION — not personal preference or novelty.
• The FIRST and MOST IMPORTANT criterion is always: ALIGNMENT WITH LEARNING OBJECTIVES. The medium must serve the intended outcome.
• The six main criteria tested on the LET: (1) Alignment with objectives, (2) Appropriateness to learners, (3) Accuracy and quality, (4) Cost and practicality, (5) Ease of use, (6) Engagement and interest.
• The correct SEQUENCE of decision-making: OBJECTIVES first → LEARNERS second → MEDIUM third. Never start with the medium and work backward.
• Appropriateness to learners means considering age, ability, prior knowledge, cultural background, and interests of the specific pupils in your class (e.g., Grade 1 learners need more concrete media than Grade 6).
• Accuracy and quality: the content must be up-to-date, factually correct, and well-produced. Outdated materials can reinforce misconceptions.
• Cost and practicality: affordable, available in the school context, and feasible to use given classroom conditions (space, electricity, equipment). This is especially relevant in Philippine public school settings.
• Ease of use: the teacher should be able to operate and manage the medium without technical difficulties disrupting the lesson.
• Engagement and interest: the medium should capture and maintain pupil attention, but ONLY if it also meets the other criteria. Engagement alone is not sufficient justification.
• The key rule: THE BEST MEDIUM IS THE ONE THAT FITS THE OBJECTIVE AND THE LEARNERS — not the most expensive, most modern, or most entertaining.

Criteria for Selecting Instructional Media

Common Mistakes

• Choosing a medium because it is expensive, high-tech, or novel rather than because it aligns with the objective.
• Reversing the selection sequence by starting with 'what media is available' instead of starting with 'what is my learning objective.'
• Using a very engaging medium (e.g., an entertaining video) that does not match the lesson objective — engagement is necessary but not sufficient.
• Ignoring learner characteristics — showing a complex infographic to Grade 1 pupils who cannot yet read fluently.
• Forgetting practicality — planning to use LCD projection in a school that has no projector or frequent power outages.

Exam Tips

• If an LET scenario asks 'what should Teacher X do BEFORE showing the video,' think PREPARATION PHASE — specifically preparing the learners with an advance organizer.
• If a scenario describes 'Teacher X wrote three questions on the board before playing the documentary,' this is the PREPARATION phase (preparing learners) — the technique used is an ADVANCE ORGANIZER.
• If a scenario asks about what happens 'after' the media, the answer involves the FOLLOW-UP phase — discussion, application, evaluation.
• The phrase 'media never teaches by itself' is a direct LET answer for items asking why the teacher's role remains important even when using technology.
• Remember the mnemonic: Before = Prepare (yourself, equipment, environment, learners); During = Present (actively guide); After = Follow-up (discuss, apply, assess).

Key Points

• Effective media use follows a THREE-PHASE CYCLE: PREPARATION → PRESENTATION → FOLLOW-UP (sometimes called 'the three P's').
• PHASE 1 — PREPARATION: This phase has FOUR targets: (a) prepare YOURSELF (preview and master the material), (b) prepare the MATERIALS AND EQUIPMENT (test that everything works), (c) prepare the ENVIRONMENT (seating, lighting, ventilation, sound), (d) prepare the LEARNERS (set a purpose, give an advance organizer so pupils know what to look/listen for).
• PHASE 2 — PRESENTATION: Deliver the material clearly. Introduce it, present it, and actively guide pupil attention to key points. The teacher does NOT simply press play and step away — the teacher remains ACTIVE during presentation.
• PHASE 3 — FOLLOW-UP: After the media presentation, DISCUSS, APPLY, and EVALUATE. Reinforce learning, answer questions, connect the media experience to the lesson objective, and assess whether the outcome was met.
• A critical principle: MEDIA NEVER TEACHES BY ITSELF. The teacher's professional framing BEFORE (preparation) and professional processing AFTER (follow-up) are what convert a media resource into actual learning.
• An advance organizer (used in the preparation phase to set purpose for learners) is a critical technique: posting guiding questions on the board before showing a video helps pupils watch with focus.
• The three-phase cycle applies to ALL types of media — whether using a chalkboard, a video, realia, or a multimedia presentation.

Principles of Media Use: The Three-Phase Cycle

Common Mistakes

• Thinking that 'preparation' means only setting up the equipment — it has FOUR targets: self, materials/equipment, environment, AND learners.
• Believing that the teacher's job ends once the media starts playing — the teacher must remain ACTIVE during presentation.
• Skipping the follow-up phase — many beginning teachers show a video and move on without discussion, application, or assessment.
• Not giving an advance organizer before media presentation — pupils without a purpose tend to watch passively and retain little.
