THE USE OF INQUIRY-BASED INSTRUCTION IN ENHANCING THE PERFORMANCE OF GRADE 9 STUDENTS IN PROJECTILE MOTION

The study aimed to determine the effectiveness of inquiry-based instruction to improve student performance in science, specifically, projectile motion using quasi-experimental research method with fifty (50) Grade 9 students from Surigao del Norte National High School in each group as participants for both control and experimental. To measure students’ academic performance, a researcher-made questionnaire was used. The data were analyzed using mean, standard deviation, and Analysis of Covariance. The result showed that the experimental group performed very satisfactorily and had a significant increase in academic performance in science which demonstrated that inquiry-based instruction had been an effective science teaching strategy in teaching projectile motion to Grade 9 students. Thus, the researchers recommended that inquiry-based instruction be implemented, applied, and incorporated in science teaching to facilitate understanding among learners.
