The Development and Usability of Optics Kit as a Teaching Aid among Physics Trainee Teachers

Abstract

This study was conducted to develop a teaching aid known as the Optics Kit. This Optics Kit consists of tools and learning modules that were designed according to form four physics DSKP syllabus. The study utilized the ADDIE Model as instructional design which embraced the quantitative survey method. The developed Optics Kit has obtained validity from the experts while its usability were conducted among physics trainee teachers which consists of 30 trainee teacher from the Bachelor of Education (Physics) programme that were selected via cluster sampling method. The instruments used in this study was the validity questionnaire and usability test which were adapted from previous research. Data analysis was conducted using SPSS software. Results obtained from this study found that the validity value of Optics Kit and the usability test based on the percentage of expert consent are 100% and 97.9%, while the mean score value for the usability of this Optics Kit is 4.98. These findings show that the Optics Kit has high validity and strong agreement on usability of the Optics Kit as a teaching aid. In conclusion, this Optics Kit was successfully developed to be used as a teaching aid for the topic of Light and Optics.
