The development of mathematics learning devices based on problem-based Learning on equation system of three variables for tenth-grade senior high school students school

Abstract

This research aims to develop the learning device in the form of RPP (lesson plan) and LKPD (student's worksheets) based on problem-based Learning (PBL) for the material of Linear Equation System of Three Variables for tenth-grade senior high school student, which are valid, practical, and effective. The type of this research is development research. This research used a Plomp's model, which consists of three phases, namely preliminary research, prototyping phase, and assessment phase. This research has not been produced the learning devices that meet the criteria valid, practical, and effective. The result of the lesson plan and students' worksheets validation sheet showed that is developed was not valid. The learning devices are not also practical yet. While the effectiveness of the learning devices has not been seen in problem-solving and self-regulated Learning yet.
