KORELASI MODEL INKUIRI TERBIMBING BERPENDEKATAN SETS TERHADAP KETERAMPILAN BERPIKIR KRITIS SISWA AbstractCritical thinking skills in chemistry subject is still low. Teacher-centered learning is one of the causes of low critical thinking skills. The objective of this study was to investigate the correlation of guided inquiry learning model with the Science, Environment, Technology and Society (SETS) approach on students’ critical thinking skills at chemical equilibrium material. The research method was Quasi Experiment with Nonequivalent Control Group Design, and the samples were taken using purposive sampling. The samples consisted of 36 students in the control and the experimental classes. The research instrument consisted of 12-item essay test which represented 11 indicators of critical thinking skill. Data analysis was performed using the Independent Sample T-test through SPSS 22 version. The results of hypothesis testing showed a correlation of the use of guided inquiry model with SETS approach on students' critical thinking skills in the experimental class with sig values <0.05. The percentage result of the posttest data showed an increase in critical thinking skills of students in the experimental class. The conclusion of this study is that the use of guided inquiry model with SETS approach can improve students' critical thinking skills. The highest critical thinking skills indicator in the experimental class is inducing and judging inductions, while the lowest indicator is observing and judging observation reports.AbstrakKeterampilan berpikir kritis pada mata pelajaran kimia masih rendah. Pembelajaran yang berpusat pada  guru adalah salah satu penyebab rendahnya keterampilan berpikir kritis. Tujuan penelitian untuk mengetahui korelasi model pembelajaran inkuiri terbimbing berpendekatan Science, Environment, Technology, dan Society (SETS) terhadap keterampilan berpikir kritis siswa pada materi kesetimbangan kimia.

This study aims to describe the differences in students’ critical thinking skill between class which use discovery learning and conventional learning in electromagnetic wave material. The research method used was a quasi-experimental method with a non-equivalent control group design which was conducted in MAS 01 Darussalam Kepahiang. In non-equivalent control group design, the sample (was) not taken randomly but by purposive sampling technique. The research sample taken by the researcher consists of two classes,  (i.e.) the class XII A2 as an experimental class and the class XII A3 as a control class. Both classes were given a pretest to find out the students’ fundamental critical thinking skills and a posttest to find out the students' final critical thinking skills. This research was conducted in two meetings according to subchapters on electromagnetic wave material. Discovery learning model was applied in the experimental class with the steps of learning are stimulation, problem statement, data collection, data processing, verification, and generalization. The average value of critical thinking of the experimental class student was 65.7 and (the) control class was 48.12 with a value of sig. (2-tailed) = 0.000 sig. α = 0.05. Based on the results, it can be concluded that there is a significant difference in students’ ' critical thinking skills using the discovery learning model with the critical thinking skills of students using conventional learning.

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.

The purpose of this study was to examine the differences in effectiveness of PBL learning models with TPS in terms of the critical thinking skills of elementary school students in mathematics. This research is a quasi-experimental study. In this study, the Non-equivalent Control Group Design design is used to investigate the effects of the two variables used. In this study 19 students at Bacem Elementary School and 19 students at Waru Elementary School, Jepon District, Blora Regency. The two groups were given different treatments, namely the PBL learning model was treated in the experimental group at Bacem SDN, and the TPS model was treated in the control group at Waru Elementary School. Based on the results of the study, H_oditotak and H_a were accepted. The analysis in this study used the Ngain test to determine the increase in the average value of the results of the pretest and posttest. This is based on the results of the NGain analysis showing an increase in value after being given PBL treatment of 0.64, while the increase in value after being given TPS treatment was 0.53. Based on all analysis results, it can be concluded that there are significant differences in effectiveness in this study. Evidently the application of PBL learning models has a higher level of effectiveness when compared to the TPS learning model of the critical thinking skills of fifth grade students in mathematics

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.
