The purpose of this study was to determine the implementation of learning by using the 3C3R model and improving students’ critical thinking skills on the topic of heat. The population of this study was all class X of SMAN 25 Bandung, amounting to six classes, the sample was class X MIA6. Sampling used a simple random sampling technique. The research method used a pre-experimental method with a one-group pretest-posttest research design. Data on the results of the implementation of learning with the 3C3R model were obtained from the observation sheet and critical thinking skills of the students’ using essay. The results showed that the average teacher activity was 98.23% with a good category, while the average activity of students was 88.93% in the good category. In addition, there was an increase in students’ critical thinking skills in the heated topic with an N-gain value of 0.65 in the medium category. The results of the hypothesis test show that t-count > t-table (17.25 > 2,045). Thus, there is an increase in students’ critical thinking skills after applying the 3C3R model to the topic of heat.
