Thinking Aloud Pair Problem Solving (TAPPS) Method: The Effect of Understanding Physics Concepts and Communication in High Schools in Indonesia

Abstract

The purpose of this research is to improve the understanding of scientific concepts and communication of high school students in Indonesia. The method used in this research is quasi experiment method with the pre-test and post-test. Subjects of the research were obtained from random cluster sampling with 60 students. The experimental class was given treatment of the Thinking Aloud Pair Problem Solving method and the control class was given the treatment of the discussion method. The results of this study indicate an increase between the pre-test and post-test understanding of concepts and scientific communication both in the experimental class and the control class. However, the experimental class experienced more significant escalation with an effect size value of 0.3 in the medium category. The further research need to be applied the use of Thinking Aloud Pair Problem Solving method in more than one class to see the consistency of Thinking Aloud Pair Problem Solving method in improving students' understanding of concepts and scientific communication.
