The development of cooperative problem solving physics laboratory model on simple pendulum concept

摘要

This study aims to develop a model of laboratory activity based on problem solving called cooperative problem solving physics laboratory (CPSPL) model. The study was conducted at a university in Bengkulu, Indonesia. This study uses research and development method with 3D model consisting of define, design, and develop stage. The define stage contains a preliminary study aimed at exploring conditions that encourage the development of the CPSPL model. The design stage contains the activity of planning the CPSPL model syntax and the experimental worksheet. The development stage contains the activities of realizing a conceptual framework in the form of a CPSPL product. At this stage the CPSPL model is validated by experts (N=3) and implemented to the pre-service physics teachers (N=40) which have been grouped into three initial problem solving abilities, namely high, medium and low level. After implementation, a final problem solving skill test is performed. Based on the data analysis, it was found that the improvement of students' problem solving skills in the three groups are in good category and not significantly different. It can be concluded that the CPSPL model can be used to improve the problem solving skills of pre-service physics teachers.
