Developing A Module on Sound Wave of Solid, Liquid, and Gas Substances through Problem Solving Model with Matlab Simulation on Wave and Optical Courses

Abstract

This study aims to: (1) to find out the results of the products developed and (2) to find out the perceptions of students regarding the Sound Wave module in Solid, Liquid and Gas Substances developed. This research is research and development (R & D) which refers to the model proposed by Thiagarajan. The feasibility of the media is validated by material experts and media experts. Subjects The trial of this study was 25 students of the University of Jambi Physics Education in 2016. The research data is in the form of module validation values by material and media experts, as well as the results of student perceptions of the module. Based on the results of data analysis, it was concluded that the assessment of wave solving and problem-solving optics modules was declared feasible with very good categories, namely with the results of material expert validation of 92%, the value of media expert validation was 86.5%. The results of the analysis of student perception data show that the print module seen from the aspect of the module cover design obtained an average percentage of 83%, from the design aspects in the module obtained an average percentage of 82%, from the presentation aspects of the module material obtained an average percentage amounting to 84.5%, from the aspect of Probem Solving obtained a percentage of 81%, and from the language aspect in the module obtained an average percentage of 84.25%. Based on these results it can be concluded that the Problem Solving-based print module on Sound Wave material in Solid, Liquid, and Gas Waves and Optics courses developed is suitable to be used as one of the learning media that can be used in the implementation of Wave and Optical subject learning.
