Development of Instructional Material in Patterns and Algebra Based on the Least Learned Competencies

This design-based research was conducted to develop instructional materials in Patterns and Algebra based on the least learned competencies of grade 8 students of Bacan National High School in the Division of Aklan for School Year 2019-2020. The researcher used a researcher-made checklist and focus group discussion guide to assess the least learned competencies of students in Patterns and Algebra, Quality Assurance tools of learning resources for the acceptability of the developed instructional materials, and test results for the performance of students before and after the utilization of the module. Research findings revealed that there are 5 least learned competencies in Patterns and Algebra which includes factoring the general trinomials, solving problems involving factors of polynomials, solves problems involving rational algebraic expressions, solving problems involving linear equations in two variables, and solving problems involving systems of linear equations in two variables by (a) graphing, (b) substitution, and (c) elimination. The five self-learning modules developed by the researcher were found acceptable and are effective instructional materials to meet the standards in the Most Essential Learning Competencies in Patterns and Algebra since that it successfully complied and passed the evaluation required by the Department of Education. Therefore, in terms of content, language, and layout and format, the developed-instructional materials are appropriate to use in order to address the concern on the least learned competencies in Patterns and Algebra. Findings revealed that after the utilization of the developed-instructional materials, students have improvement in their academic performance. Consequently, there is a significant difference in the performance of students before and after the use of module.
