Development of Digital-Worksheet on Social-Arithmetic Based on Problem Based Learning for Grade 7th

Abstract

There are many aspects of everyday life that apply mathematics concepts at some level, one of them is social arithmetic. However, many students have difficulty learning this subject. Many students have difficulty determining the appropriate arithmetic concept to apply in solving problems. As a result, students are ultimately unable to solve the problems they face. Furthermore, the majority of students are not accustomed to solving contextual problems that apply mathematical concepts to solve real-life problems. Students generally focus on calculation skills without understanding the concept or which concept is appropriate to apply. Therefore, social arithmetic learning should be designed as a real-life problem-solving activity. Therefore, in this study, problem-based learning media was developed for social arithmetic material. The learning media developed is digital, in accordance with the demands and needs of the current educational world. This study uses the Research and Development method with the ADDIE model. The product trial on material validation obtained 82.85% on valid criteria, 83.16% on aspects of media development, and 88.16% on practical criteria. The use of this learning media supports students' understanding of the use of mathematical concepts in solving real-life problems. Furthermore, Problem-Based Learning (PBL) supports students' ability to identify and apply appropriate mathematical concepts to solve given problems. This is demonstrated by the average student learning outcome of 89.8.
