Abstract

This research aims to produce learning tools in the form of a Learning Implementation Plan (RPP) and Student Worksheets (LKPD) with Problem Based Learning (PBL) Model oriented Mathematical Critical Thinking Ability that has proven its validity. The type of research used is Development Research using a modified ADDIE development model, namely the Analysis, Design, Development, and Evaluations stages. At the Implementation stage, it was not implemented because it was based on government policy that schools only conducted online learning due to the covid-19 outbreak. The instruments and data collection techniques were in the form of RPP and LKPD validation sheets, with validating learning tools by 2 persons of FKIP UIR Mathematics Education Lecturers and 2 persons of Mathematics Teachers. The data analysis technique used is the analysis of the data from the validation of learning tools using descriptive statistics. The results showed that the results of the validity of RPP for each aspect were 84,13% with a very valid validity level and for each validator were 84,84% with a very valid validity level, while the results of the validity of LKPD for each aspect were 84,59% with a very valid validity level and for each validator were 84,42% with a very valid validity level. Based on the results of the development of these learning tools, then obtained a Learning Tools with Problem Based Learning (PBL)’s model Oriented to the Mathematical Critical Thinking Ability in Quadrilateral Material for Grade VII of Junior High School which had its validity tested.
