Parabolic instructional device: It’s effectiveness in teaching concepts of projectile motion

The study constructed and developed Parabolic Instructional Device in Teaching Concept of Projectile Motion in Physics and determined the acceptability and its effectiveness on the performance of learners. The study utilized Research and Development, Quasi-experimental and Descriptive-comparative Research Design. The statistical tools used in the study were average weighted mean, standard deviation, Cohens’ d effect and T-test for dependent and independent sample. The data gathered from validation sheets were treated statistically through average weighted mean and were discussed qualitatively.
