Abstract

This study aims to determine the feasibility of developing an mathematics story book. The method used in this study is "Research and Development". Meanwhile, the data collection technique in this study was a validator questionnaire from the experts, then quantitative and qualitative data were analyzed descriptively.Based on the results of research and development that has been done, it shows that: mathematics story books get a very decent percentage value. This percentage is obtained from the results of the validation of each expert i.e. Material experts with a percentage of 80.92%, experts in presenting material with a percentage of 79.16%, media experts giving a score of 93.75%, and linguists giving a score of 81.25%. So it can be concluded that the average value of the percentage of experts is in the very feasible category with a percentage value of 83.77%. Based on the explanation above, it can be concluded that the electronic mathematics storybook is very suitable to be used as a learning tool in class VII SMP in comparison material. Keywords: development, mathematics storybook, comparison.

Abstract

This study aims to produce mathematics learning media products in the material of flat side space. The media is designed with the Articulate Storyline application with a visualization of understanding the concept of flat-sided building materials as a tool in explaining the concept of flat-sided building materials and improving student learning outcomes in class VIII of flat-side building material. The method used in this research is the Research and Development (R&D) method. This research method consists of several phases, namely: analysis of the potential and problems that exist in the research site, the second phase of literature studies and collection of information related to problem handling and based on existing potential, the third phase of designing the product, the fourth phase of designing the product, the fifth phase of expert validation, and getting tested product designs. Design validation is carried out by experts consisting of media experts, material experts, and teachers. Research data in the form of expert validation results obtained at 4.48 with the interpretation into the very valid category. In this way, the learning media is ready to be applied to the trial process and large classes in further research and development methods. Keywords:. mathematics learning media, articulate storyline, build flat side space
