Development and Validation of Video Lessons as Supplementary Materials in Teaching Heredity Among Grade 10 Students

Abstract

This study aimed at developing video lessons that can be used as supplementary materials in teaching heredity among grad 10 students. This study emphasizes the integration of STEM education using video lessons to explain the concept of heredity. The researchers administered needs assessment survey to five (5) in-service science teachers to gather valuable information about the significance and needs to develop video lessons on heredity. The needs assessment results show a high demand for video lessons as these will not only make learning more interactive and interesting, but they also pique the curiosity of students and teachers alike. For the development of video lessons, the researchers followed 4D model. It was designed as engaging, interactive, and provides illustrative visuals to improve the students conceptual understanding on the lessons under heredity. The developed materials were evaluated by five (5) science teachers in terms of its content, instructional, technical quality, conceptual error, accuracy and up-to-datedness of information. The evaluation result revealed that the developed video lesson passed all the categories and was rated as ‘excellent’ M = 3.56. Therefore, the developed video lessons were recommended and accepted for its distribution to utilize as instructional material in supplementing the teaching of heredity among grade ten students.
