LET Secondary Social Sciences — Information TechnologySlides
If you commute to a LET Secondary review centre (or watch Super Tutor on the jeepney), these Information Technology slides are designed for exactly that. Each slide holds one idea, one visual cue, and one PRC-style question pattern — ready for quick bursts of review between stops.
Exam context
The Licensure Examination for Professional Teachers — Secondary is conducted by Professional Regulation Commission (PRC) and is scheduled for Bi-annual. The Social Sciences subtest is marked as "Core" in the official pattern, and Information Technology appears in position 6th of 8 in the LET Secondary Social Sciences review rotation. Passing mark: Weighted average of 75% with no grade below 50%. Recent LET Secondary 2026 papers have drawn roughly a meaningful share of questions from this subject.
Information Technology - Slides
Information Technology (IT) has become essential for 21st-century teaching and learning. As future elementary educators, you must understand IT fundamentals, digital citizenship, and how to integrate technology safely and effectively in K-6 classrooms. This chapter prepares you for LET questions on IT basics, online safety, and teaching technology responsibly according to DepEd policies and Philippine laws.
