This research is experimental research and the objectives were to 1) develop Critical Thinking and Problem-Solving Thinking after Physics learning with Computational Thinking 2) Analyze the relationship between Critical Thinking and Problem-Solving Thinking. The population for studying were 130 twelfth grade students from 3 classes in the first semester of the 2022 academic year at Prachinratsadornamroong School, Mueang Prachinburi District, Prachinburi Province. Researcher designed the Physics methodology with Computational Thinking by 6Steps to Success on Electromagnetic force for 12 grade students. The experimental group exercised for 8 periods-50 minutes per period. This research used Critical Thinking and Problem-Solving pretest-posttest for collected the data. Data were analyzed by using percentage, mean, standard deviation and coefficient of variance. Hypothesis were tested by using t-test for Dependent Sample and Simple Correlation. The results of this research were as follows: After Physics learning with Computational Thinking by 6Steps to Success is 1) Satisfy Experience 2) Specify a Challenge 3) Search and Solve 4) Shape the ideas 5) Simple Science and 6) Summary and Evaluate) students’ learning skill was significantly increased at the .05 level. The percentages of assessment results for Critical Thinking (CTC) and Problem-Solving Thinking (PRB) variables after learning were higher than before for all indicators and the results of the assessment were at a high level representing 82.30 and 61.54 percent, respectively. The average overall is 71.92 percent, which was based on the hypothesis. For the students’ Critical Thinking and Problem-Solving Thinking, the correlation was significantly in high level related at the .05 level.
