Abstract
This study focused on development of intervention material utilizing Kotobee Application as an aid for Grade 10 students as they dealt with modular distance learning at Lagundi-CCL National High School. This study utilized descriptive-developmental, and experimental research design utilizing assessment test and adopted questionnaire-checklist. In addition, the study used two groups of respondents. The first group was composed of thirty (30) Grade 10 learners who were chosen purposively based on the results of Learning Outcome Assessment during the first quarter. The second group was comprised of five (5) Mathematics experts who had evaluated the developed intervention material. Based on the result, the student-participants performed Very Satisfactory in geometric sequence, factoring polynomials, polynomial equations, and problem solving involving polynomial equations after exposure to the intervention material using Kotobee application. Moreover, the teacher-respondents evaluated the developed learning material Very satisfactory with respect to its content quality, instructional quality, and technical quality, and other findings. The results of this research may serve as basis of Mathematics teachers in Lagundii-CCL NHS to continue the provision of intervention material to improve students’ performance. More so, other subject teachers can use the findings in developing their own material.
