Abstract

The purpose of this development research is to produce a product in the form of mathematics learning tools on linear equation system onproblem based learning models. The type of research used is the 4D development model which has been modified into 4 stages, namely the define stage, the design stage ,and the development stage. construction, and evaluation and revision phases. Instruments and data collection techniques used a questionnaire in the form of a validation sheet designed using a 4-level Likert scale. Validation was carried out on four validators, namely two mathematics lecturers at the Faculty of Teacher Training and Education, Islamic University of Riau and two mathematicsteachers. The data analysis technique used is a deskriptif analysis technique by describing the results of the analysis of the data from the validation results. The results obtained in this study are the results of the validation of learning tools with an overall average on RPP of 87,36% with very valid criteria or can be used without revision while the oerall average on LKPD of 88,17% with very valid criteria or can be used without revision. Therefore, the conclusion of this study is to produce a product in the form of mathematics learning tools on problem based learning with linear equation system that has been tested for validity.
