Validity and reliability CBSL model to improve critical thinking skills and student’s responsibility

Abstract

Collaborative based Science Learning (CBSL) Model was a model that can be used in science learning to improve critical thinking skills and responsibility of junior high school students. The syntax of the CBSL model includes: 1) Motivation and problem orientation, 2) Collaborative-based critical thinking activities, 3) Communicating the results of collaborative critical thinking activities, 4) Advanced practice of critical thinking and responsibility, and 5) Reflection. This study aims to describe the validity and reliability of the CBSL model that has been developed. The validity and reliability data of the CBSL model is obtained through Focus Group Discussion (FGD) activities. The results showed that the CBSL model met the requirements of validity (rα = 0.860) and reliability (α = 0.980), so that the CBSL model met the validity and reliability requirements. The implication of this research is that a valid and reliable CBSL model can be used to improve students critical thinking skills and student responsibility theoretically.
