Abstract

This study aimed to develop video materials on the least learned competencies in Mathematics 7 of Mimbunga National High School, Gingoog City, Division of Gingoog, Misamis Oriental, Region 10. The topics of the developed video lessons are "Addition of Polynomials and Subtraction of polynomials". The evaluators of the video materials were 15 Grade 7 learners, three (3) Mathematics Teachers, and one Mathematics Supervisor. They were tasked to watch the video materials and rate them using the tools in evaluating video learning resources. Then, the video lessons were evaluated and validated by the Leaning Resource Management and Development System (LRMDS) in this Division. After the evaluation, the contextualized video lessons were deposited in Learning Resource Portal, ready to use at the district level and for everybody who can use it. This research used the ADDE Model (Analysis, Design, Development and Evaluation). The findings of the study revealed the following: (1) The least learned competencies for Second Quarter in Mathematics 7 are adding polynomials and subtracting polynomials. (2) Video materials being developed and validated were based on the identified least learned competencies for Second Quarter in Mathematics 7. The topics were the addition of polynomials and the subtraction of polynomials. (3) Based on the comments and suggestions made by the learners, teachers, and expert, the video lessons only require minimal revision or enhancement. These include the font size or text must be increased, color combination and usage must be changed to light colors, the audio quality, and the appropriate music background in the video lessons. All of the feedback from the evaluators about the video lessons are satisfactory. (4) The video materials can be institutionalized at the district level after they pass on the requirements and standards set by the Learning Resource Management and Development System (LRMDS) in evaluating non-print instructional learning resources. The following conclusions are (1) The students lack prior knowledge and skills in adding and subtracting polynomials which is a pre-requisite lesson on the operation of integers. (2) The developed video lessons can be used as supplemental learning materials in teaching Mathematics 7. (3) The video materials were rated with minimal revisions. Therefore, the video lessons were accurately and appropriately developed. (4) Institutionalization of the video materials comes after the quality assurance process at the district level to assure instructional and technical quality.
