PENGEMBANGAN PERANGKAT PEMBELAJARAN MATEMATIKA DENGAN MODEL PEMBELAJARAN CREATIVE PROBLEM SOLVING (CPS) POKOK BAHASAN SEGIEMPAT DAN SEGITIGA

Abstract

This aims of the study are to develop a product in the form of mathematics learning devices with Creative Problem Solving (CPS) learning model on square and triangle materials.The mathematics learning device development consist of Lesson Plan, and Student Worksheet .This research was a research development with the reference Four-D model (Define, Design, Development and Disseminate)by S. Thiagarajan. This research was only carried out up to the Development stage, namely only up to the validation stage by experts without direct field trials. The result of data analysis can be concluded, the validation result of 3 validators showed that the mathematics learning devices with Creative Problem Solving (CPS) learning model of Lesson Plan were declared valid with score 4,43,and Student Worksheet were declared very valid with score 4,33 feasible to be tested in the field.
