Abstract:

This study aimed to determine the acceptability of the improvised Compact Image Projector (CIP) in teaching Optics at Tanay West National High School in Tanay, Rizal. The study's respondents were the sixty (60) Grade 10 learners of Tanay West National High School. The study used two methods of research, the experimental and descriptive-developmental methods, to determine the performance of the student-respondents and the acceptability of the developed Compact Image Projector as an improvised science apparatus with regards to functionality, durability, utility value and economic value. Based on the analysis and interpretation of data gathered, all mean scores in the posttest of the experimental and control group were higher than the pretest, which denoted that there was an increase in the level of performance of the groups of respondents. Moreover, the study found out that the level of performance of the experimental and control groups as revealed by their pretest and posttest, differed significantly with respect to different lessons in Optics thus, the null hypothesis was rejected and was verbally interpreted as significant. The result revealed that there is significant difference between on the posttest results on the level of performance of the experimental and control group with respect to Nature of light, Reflection of Light and Mirrors, Image Formation by Mirrors, Refraction of Light and Lenses, Image Formation by Lenses and Mirror/Lens Equation since all of their p-values are less than the 0.05 significant level.
