This study aimed to investigate the effectiveness of Strategic Intervention Material (SIM) in Mathematics as remediation for Grade 9 students in solving problems involving quadratic functions. The SIM was designed as a remediation tool for students in teaching one of the least learned competencies. It was personally conducted by the researcher in Digos City NHS – Igpit HS Annex, Igpit, Digos City, Davao del Sur, Philippines during the School Year 2016-2017. A total of 16 Grade 9 students were the respondents of the study. Quasi-experimental design was used. The data were gathered using the researcher-made pretest and posttest. Frequency, relative frequency, mean and standard deviation were used to describe the academic achievement of students in problem solving involving quadratic functions. One-way analysis of co-variance (ANCOVA) was utilized to test if the significant difference existed between the experimental and the control groups. Findings revealed that the proficiency level of Grade 9 students in the posttest when remediated using the SIM was “satisfactory”; while the students remediated with the Grade 9 Learner’s Material was described as “did not meet expectations.” A significant difference in the academic achievement of students on the topic in favor of the experimental group was noted; hence, the Strategic Intervention Material in Mathematics was found effective as a remediation tool for Grade 9 students in solving problems involving quadratic functions. Recommendations were offered.
