Computer based recitation program development with feedback in Newton’s law topic

This research was conducted to develop a recitationprogram on Newton's law and test its practicality. This type of research is Research and Development (R&D) with a Four-D (4D) model with stages, namely Define, Design, Develop, and Disseminate. Theresearch subjects were 38 third-semester physics students at the State University of Malang. The data collection technique was carried out using a media validity test questionnaire and a content validity test given to 2 validator lecturers, as well as a practicality test questionnaire and a questionnaire on the perception of the use of each item given to students. The resulting data is the percentage of validity test assessments, practicality tests, and student perception questionnaires, as well as suggestions were given by lecturers and students regarding the recitation program. This research resulted in a recitation program in which there were 38 questions accompanied by feedback. Theresults of the content validity test obtained a value of 95.7%, while the results of the media validity test obtained a value of 93.75%, so it is included in the very valid category. Then, the results of the practicality questionnaire showed that students agreed that the recitation program made it easier to understand Newton's law concepts, helped strengthen their understanding of Newton's law concepts, and this program was of interest to them. Meanwhile, based on the student perception test results regarding the item items' use, an average of 96.6% wasobtained, which means that the questions, feedback, and discussion videos in the recitation program were very easy to understand.
