Development and validation of worksheets to address the least learned competencies in Mathematics 4

This study identifies and addresses the least learned competencies in Mathematics among Grade 4 learners in La Purisima Elementary School, Prosperidad District II, Division of Agusan del Sur, for the school year 2023-2024. The research utilized a development research design and involved 31 learners. The research instrument consisted of the Third Periodical Test Questionnaires. Statistical treatments such as frequency, count, percent, weighted mean, t-test of difference, and analysis of variance were employed in analyzing the data. The researcher utilized the consolidated researcher-made worksheet with topics covering the least learned competencies identified for the third quarter. The study used a development research design, particularly the ADDIE Model phases, namely: Analysis, Design, Development, Implementation, and Evaluation. In the Analysis stage, the least learned skill (LLS) was identified based on the item analysis of the third grading quarterly test. From the LLS obtained, the researcher designed and developed Worksheets in mathematics 4. These materials underwent validation before implementation as intervention materials. Post assessment results showed that the majority of the learners who were previously identified in the Not Mastered Level (51.6%) had moved up either to the Nearly Mastered Level (48.4%) or Mastered Level (51.6%). Nobody was left in the Mastered Level. This strongly support the effectiveness of the validated Worksheets in Mathematics 4.
