Abstract
The study sought to determine the effectiveness of the developed and validated Interactive Multimedia Materials in selected topics in Chemistry for Grade 10 students at Sta. Lucia High School, Division of Pasig City. Descriptive method and one-group experimental method of research were used in the study. The researcher used 52 Grade 10 students. The least mastered topics in Chemistry were Gas Laws. The experts and the teachers’ respondents evaluated the developed IMM as “Satisfactory” with respect to Format, Content, Appropriateness and Updatedness. On the other hand, in terms of Presentation and Organization, the experts evaluated it as “Very Satisfactory” while the science teachers as “Satisfactory”. In terms of its Technical Aspect, both groups of the respondents evaluated the IMM as “Very Satisfactory”. Likewise, there was no significant difference between the perceptions of the experts and the science teachers on the developed material. Moreover, the level of performance of the learner respondents in the pretest was “Satisfactory”, “Moderately Satisfactory” and “Needs Improvement”. On the other hand, the level of performance of the learners in the Posttest was “Very Satisfactory” and “Satisfactory” for the topics in Gas Law and there was a significant difference in the mean scores of the pretest and posttest of the learners. Comments and suggestions were given by the respondents to further improve the interactive multimedia materials in Chemistry 10.
