The Validity of Problem-Based Learning Model Learning Tools With A Contextual Learning Approach

Abstract

The purpose of this study was to describe the feasibility of verifying the results of physics learning tools using a problem-based learning model with contextual learning. This research was conducted at Muhammadiyah Batudaa High School, using research samples from class XI-IPA1. Identification of the sample in this study using simple random sampling. This research is a development research using the ADDIE research and development (R&D) model developed by Reiser and Mollenda which includes the stages of analysis, design, development, implementation and evaluation. Validation testing is carried out at the development stage. The results showed that the test results with an average score of 3.7 to 3.92 were classified as very valid and suitable for use.
