Three parts of 21 century skills: Creative, Critical, and Communication Mathematics through Academic-constructive Controversy

Abstract

This study aims to analyze the characteristics of critical, creative and communication thinking after participating in learning academic-constructive controversy. Sequential explanatory design with sequential phase design analysis was used for the test results of two classes of junior high school students. The results showed that the experimental group was better than the control group for creative, critical, and communication mathematic. Completeness of the characteristics of the three abilities is in line with the ability of students, but they experience obstacles to communicating. Unfortunately, this study is only limited to quadrilateral topics. Academic-Constructive controversy learning can be used to develop three skills or even develop character qualities going forward.
