DEVELOPMENT OF LEARNING DEVICES USING PROBLEM-BASED LEARNING MODELS TO FACILITATE MATHEMATICAL PROBLEM-SOLVING ABILITY FOR CLASS XII SMA/MA ON COUNTING METHODS

Abstract

This research is development research which aims to produce a syllabus, learning implementation plan (RPP), and student worksheets (LKS) with a Problem-Based Learning model to facilitate mathematical problem-solving abilities in class XII SMA/MA on counting methods. This development research uses a 4-D development model. The instruments used in this study were validation sheets to assess the validity of learning tools (syllabus, lesson plans (RPP), and worksheets (LKS)) and student response questionnaires to assess the practicality of worksheets. For this study, from the results of the analysis of the validation sheet data, the average syllabus value was 3.73, with a very valid category. The average value of lesson plans is 3.70 with a very valid category, and the average value of the LKS is 3.67 with a very valid category. Whereas for data analysis of student response questionnaires, very practical results were obtained with a value of 3.55. Based on data analysis and discussion, it can be concluded that the syllabus, lesson plans, and worksheets developed in this study met the very valid criteria, and the developed worksheets met the very practical criteria.
