Abstract: This study evaluated the efficacy of a teacher-made Strategic Intervention Material (SIM) in improving Grade 10 students' knowledge of demonstrative pronouns. A quasi-experimental research design was utilized with 46 purposively selected Grade 10-Garbanzos students as respondents and Paired T-test was used in interpreting data. Findings showed that students' mean scores improved significantly from 8.57 (low knowledge level) in the pretest to 21.30 (high knowledge level) in the posttest, with a mean difference of 12.73. Statistical analysis revealed a highly significant difference between pretest and posttest scores t(45) = -19.585, p<0.001. The calculated effect size was very large (Cohen's d=2.89), indicating a substantial practical magnitude of improvement which was highly significant. In addition, the SIM was found informative and acceptable by the students. These results provide strong evidence that the teacher-made Strategic Intervention Material is an effective tool for fostering students' knowledge of demonstrative pronouns.
