ABSTRACTThis research is aimed to know the differences increase critical thinking skills through learning group and individual problem solving in thermochemical material. This research uses a quasi-experimental design with nonequivalent control group design and study sample consisted of 103 students, divided into the first experimental (group problem solving) (35 students), the two group experimental (individual problem solving) (34 students). The collected through pretest-posttest. The analyzed with the Kruskal Wallis test, the results showed that the learning problem solving as a group or individually can improve students’ critical thinking skills. Statistical test there are significant differences in the students critical thinking skills thermochemical material between students who received group and individual problem solving. Critical thinking skills improvement with problem solving individual learning higher compared with group learning problem solving.Keywords: problem solving learning, critical thinking skillsABSTRAKPenelitian ini bertujuan untuk mengetahui perbedaan peningkatan keterampilan berpikir kritis siswa melalui pembelajaran group dan individual problem solving pada materi termokimia.

This research aims to determine the effect of Problem Based Learning using puzzle media on students' critical thinking. The study population was all grade VII students at SMP Muhammadiyah 3 Bandar Lampung totaling 192 people. The research sample was students from 2 classes, namely class VII D and VII F who were selected from the population by using purposive sampling technique. The research instrument used a pretest-posttest sheet. The design used is the nonequivalent control group design. The data analysis used t-test with a significance of 5%. The results showed a sig significance value. (2-tailed) 0.13 <0.05, which means that the n-Gain mean of critical thinking learning outcomes of students between the experimental class and the control class is significantly different. Thus, it is known that the problem-based learning model using puzzle media can affect the critical thinking skills of students.

Maka disimpulkan bahwa terdapat pengaruh model PjBL – STEM terhadap peningkatan keterampilan berpikir kritis dan self efficacy peserta didik kelas X pada materi ekosistem. An analysis of students' critical thinking skills and self-efficacy: The influence of PjBL-STEM on ecosystem learning materials Abstract: This research aimed to determine the influence of the PjBL model with the STEM approach on students' critical thinking skills and self-efficacy. This research is a quasi-experimental research with a nonequivalent control group design. This research also involved two research subjects, namely the experimental class and the control class. The population of this research was the tenth-grade students of SMA Gajah Mada Bandar Lampung. The samples were determined using the cluster random sampling technique. In collecting the data, the researchers employed a critical thinking test and a Likert scale questionnaire. The research data were analyzed using the ANOVA test. The results showed that the experimental class’s average score on the pretest experienced an improvement, from  64.96 to 84.24. The PjBL model with the STEM approach improved students' critical thinking skills and self-efficacy. The improvement was marked by the average pre-test and post-test scores improvement for each indicator, from 60.86 to 81.22. The improvement of pretest and posttest scores determined by the N-gain test was 0.55 or 31%. Furthermore, the average self-efficacy score obtained by the experimental class was 135.04, or 93% within the excellent category. Therefore, it can be concluded that the PjBL model with the STEM approach influenced the tenth-grade students' critical thinking skills and self-efficacy on ecosystem learning materials.
