Abstract
Abstract Critical thinking has become one of the main competencies of learning at the level of higher education in Indonesia, and teaching interventions that lead to the achieving of these competencies are important to do. One of the learning models developed to promote critical thinking ability is the Inquiry Creative Process (ICP), a learning model. This research aims to describe the effectiveness of the ICP learning model to promote the critical thinking ability of prospective physics teachers. The implementation of the ICP learning model involved prospective physics teachers at four higher education institutions in the province of West Nusa Tenggara - Indonesia, that are the Mataram University (UNRAM), Teacher Training and Education Institut of Mataram (IKIP Mataram), Mataram State Islamic University (UIN Mataram), and the University of Muhammadiyah Mataram (UM Mataram). This study is experimental research, where is for each group performed pretest, implementation of the ICP learning model, and then posttest. The critical thinking ability of prospective physics teachers was measured using a critical thinking ability test instrument. The data of critical thinking ability were analyzed descriptively and statistically, where the homogeneity, normality, t-test, and ANOVA test were conducted. The results showed that the implementation of the Inquiry Creative Process learning model was effective to promote the critical thinking ability of prospective physics teachers. Descriptions of further research results are described in this article.
