Development of Technology-Enhanced Lessons in Optics (TELO)

This study developed and validated Technology-Enhanced Lessons in Optics (TELO), particularly teaching electromagnetic spectrum light. It adopted the Research Development (R&D) methodology, anchored on Input-Process-Output (IPO) Substitution, Augmentation, Modification Redefinition (SAMR) models. A needs–assessment survey selected topics light that need technology enhancement was done first before material developed. panel of evaluators who were chosen purposively evaluated content validity TELO terms its objectives, content, activities, assessment techniques using a validation rating scale. The weighted mean used to describe TELO. Results needs-assessment revealed all are included development material. is highly valid techniques. applies principles activities can be considered interesting engaging if they theory constructivism SAMR model as support stimulates many senses allows learners opportunities construct their own ideas by integrating existing knowledge with new one.
