Abstract

The lack of learning media and teacher creativity in implementing mathematics learning results in a lack of students' understanding and enthusiasm in learning mathematics. This research aims to analyze the design, feasibility, effectiveness and response of teachers and students in implementing virtual reality learning based on case-based learning in class VIII mathematics subjects. The research uses the Dick and Carey development model. The research subjects consisted of two content experts, one instructional design expert, one learning media expert, three individual test students, nine small group test students, and thirty-two field test students. The data collection methods used were interviews, questionnaires, tests and documentation. The data analysis techniques used are quantitative descriptive analysis, inferential statistical analysis (t-test), and N-Gain test. The content expert test results showed very high validity based on Gregory's validity. The expert test found, the score percentage is considered very good. Based on the t-test calculation, the significance value (Sig. 2-tailed) of 0.000 is smaller than 0.05 (p > 0.05), rejecting the null hypothesis (H0) and accepting the alternative hypothesis (Ha). So, it can be concluded that there is a significant difference in learning outcomes before and after using virtual reality based on case-based learning. The N-Gain calculation produces a score of 0.741, which indicates a high category so it can be concluded that the use of virtual reality learning based on case-based learning is effective in improving student learning outcomes in class VIII mathematics subjects.

Abstract

Considering that mathematics material has an important role in everyday life, learning media in learning requires learning media to present learning material that is abstract to become concrete. Interactive multimedia can increase student learning outcomes in mathematics. Apart from that, the PBL learning model is able to encourage students to learn actively in solving a problem. Therefore this research aims to develop interactive multimedia with problems based on learning in mathematics for class VII students of junior high school. This type of research is development research with the ADDIE model which includes five systematic stages in it. The data collected are quantitative data and qualitative data using 3 data collection methods, namely interviews, questionnaires, objective tests. The stages of the ADDIE model which consists of five stages, namely the stages of analysis, design, development, implementation and evaluation. The results of this study indicate that problem-based interactive multimedia learning is valid with very good qualifications. Moreover multimedia interactive learning with problem-based learning was effectively used in learning class VII mathematics set material at junior high school.
