This study aims to determine the implementation of cooperative learning models using type Student Facilitator and Explaining (SFAE) and the improvement of students' critical-thinking skills in momentum and impulses topic. We use pre-experiment design, with the one-group pretest-posttest. The population of this study was class X MIA YAS Bandung with the sample of class X MIA 2 amounted to 30 students selected by random technique. We use the observation sheet as the instrument to observe the implementation of teacher and student activities during the cooperative learning model type SFAE. The essay tests are used to measure the improvement of students' critical-thinking skills. The results of the study showed that the implementation of teacher activities was 81% and student activities by 77% in the good category. Increasing students' critical-thinking skills is the medium category with an average normalized gain value of 0.63. Based on the results of hypothesis testing using the paired sample t-test, it was obtained t-count (34.08) > t-table (2.052) which means that Ho was rejected and Ha was accepted. It was concluded that there was an increase in students' critical-thinking skills after applying the SFAE type cooperative learning model to the material of momentum and impulse. Thus, this learning model of type SFAE can be used to improve students' higher-order thinking skills.

This research is motivated by mathematical critical thinking skills and students' learning independence that is not yet optimal becomes something that teachers need to pay attention to their students by providing an appropriate learning model to foster this. Based on the 2013 curriculum advocates the development of learning outcomes in cognitive and affective components developed simultaneously and proportionally. This study aims to determine the effectiveness of Jigsaw type cooperative learning models on mathematical critical thinking skills and student learning independence. This type of research is a quasi-experimental research. This study uses a Pretest-Posttest Control Group Design research design. The research instrument was tested for validation by content validation before being trialled. Data analysis techniques in this study were Multavariate Normality Test, Covariance Matter Homogeneity Test, Hotelling Trace T2 Test and t Test. In the preliminary data analysis, which was taken from the daily test scores and scale sheets of the pretest attitude of students' learning independence, showed there was no difference in the average mathematical critical thinking ability and student learning independence between the experimental class and the control class. In the final data analysis taken from the posttest, it can be concluded that the average mathematical critical thinking ability that uses the Jigsaw type cooperative learning model is better than the conventional learning model. But the results of the study also showed the average independence of student learning using the Jigsaw type cooperative learning model is the same as the conventional learning model.
