The Validity of the Learning Media Design Based on Creative Problem Solving (CPS) Model

摘要

This study aims to produce learning media in the form of RPP (Lesson Plan) and LKPD (Student worksheet) based on Creative Problem Solving (CPS) model. RPP is one of the learning media that must be prepared by a teacher before starting learning activities. While, LKPD is a learning media that can help students learn. This is a design research. Whereas, the model employed was Plomp model. Learning media were validated by 5 validators. Data from the validation sheet were analyzed using a quantitative analysis. From the analysis, it was found that the RPP developed based on CPS model was valid with average of 3.44, and the LKPD developed based on CPS model was valid with average of 3.39 in terms of presentation and feasibility of contents, 3 in terms of graphic, and 3.8 in terms of linguistics.
