Development of Macromedia Flash-Assisted Mathematics Learning Media with the Application of Problem Based Learning Models to Improve Computational Thinking Ability and Self-Efficacy of Class X High School Students

Abstract

This development research uses a 4-D design model by Thiagarajan, namely define, design, develop, and disseminate. However, in this study only at the development stage. The subjects of this study were 20 students in class X Mathematics and Natural Sciences at the Private MA Miftahul Falah Diski. The validity of the learning media developed in terms of the analysis of the results of the validity of the learning media by the validators with a total average value of 3.72 (category "Valid"). Meanwhile, the practicality of learning media is seen from the observation score of the implementation of learning in the second trial, which is 3.71 (category "Well Implemented"). The effectiveness of learning media in terms of four aspects, namely classical completeness, student active activity observation scores, student self-efficacy scores, and student responses. The classical completeness of students' computational thinking ability in the second trial was 87% (17 students). The average percentage of students' achievement in the ideal time of activity in the second trial for three meetings was 21.98%, 20.2%, 21.7%, 26.5%, 10.9%, and 1.9%. The average score of the overall self-efficacy scale in the second trial for three meetings was 3.16 so it was included in the positive category. The average student response in the second trial was 91.6% (category "Interested"). Based on the normalized gain index, it was found that in the second trial there was an increase in the value with a score of 0.4 (the "medium" criterion). The average score of the overall self-efficacy scale in the second trial for three meetings was 3.16 so that it was included in the positive category. The average student response in the second trial was 91.6% (category "Interested").
