Development of Learning Devices Based on Problem Based Learning Models in Improving Students' Concept Understanding Ability

Abstract

This study aims to: (1) describe the validity, practicality, and effectiveness of learning tools developed through problem based learning models in class VIII of SMP Negeri 1 Sitahuis; (2) To analyze the improvement of students' conceptual understanding ability after using the developed learning tools. This research is categorized into Development Research using the Thiagarajan, Semmel and Semmel learning device development model, namely the 4-D model (Four D Model). The research was carried out in class VIIIA in the odd semester of the 2021/2022 academic year at SMP Negeri 1 Sitahuis. The results showed that: (1) Learning tools with problem based learning models in improving students' mathematical concept understanding skills that were developed already met the valid, practical, and effective criteria; (2) Increasing the ability to understand mathematical concepts using learning tools with problem based learning models that have been developed seen from the average N-gain value in trial I and trial II, which are 0.40 and 0.58, respectively. medium category.
