@article {660, title = {THE COMPARISON OF OR-IPA TEACHING MODEL AND PROBLEM BASED LEARNING MODEL EFFECTIVENESS TO IMPROVE CRITICAL THINKING SKILLS OF PRE-SERVICE PHYSICS TEACHERS}, journal = {Journal of Baltic Science Education}, volume = {17}, year = {2018}, month = {April/2018}, pages = {Continuous}, type = {Original article}, chapter = {300-319}, abstract = {Critical thinking skills are one of the 21st century skills that are effectively trained by using the OR-IPA and Problem Based Learning (PBL) Model, therefore this research aims to compare the effectiveness of both. Research design used True Experiment with Randomized Subject Control-group Pre-test and Post-test with 94 pre-service physics teachers. Data collected using the critical thinking skills test and the student response sheet, and then analyzed using t-test and N-gain. The results showed: (1) the teaching instruments of OR-IPA and PBL Model have fulfilled the validity requirements (rα ~ .26) and reliability (α = .96 - .99). (2) Each of OR-IPA, PBL, and Conventional Model can significantly increase critical thinking skills at α = 5\%, respectively with average N-gain: medium (.60), medium (.48), and low (.14); with the student response of: very positive, very positive, and less positive. (3) The OR-IPA and PBL Model are effective to improve critical thinking skills, while the Conventional Model is ineffective, and the OR-IPA Model is more effective compared to the PBL Model. Implication of this research is that the OR-IPA Model can be an innovative solution to improve critical thinking skills, but there is still a need for repetitive research like this.}, keywords = {and PBL model, basic physics, critical thinking skills, OR-IPA model, pre-service physics teachers}, issn = {1648-3898}, doi = {https://doi.org/10.33225/jbse/18.17.300}, url = {http://oaji.net/articles/2017/987-1523527582.pdf}, author = {Budi Jatmiko and Binar Kurnia Prahani and Munasir and Z.A.
