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. Metode penelitian adalah Quasi Experiment dengan desain Nonequivalent Control Group Design, dan teknik yaitu purposive sampling. Sampel penelitian sebanyak masing-masing 36 orang pada kelas kontrol dan eksperimen. Instrumen penelitian berupa tes esai sebanyak 12 butir soal yang mewakili 11 indikator keterampilan berpikir kritis. Analisis data menggunakan Independent Sample T-test melalui SPSS versi 22. Hasil uji hipotesis menunjukkan adanya korelasi penggunaan model inkuiri terbimbing berpendekatan SETS terhadap keterampilan berpikir kritis siswa kelas eksperimen dengan nilai sig. < 0,05. Hasil persentase data posttest menunjukkan adanya peningkatan keterampilan berpikir kritis siswa pada kelas eksperimen. Kesimpulan dari penelitian ini bahwa penggunaan model inkuiri terbimbing berpendekatan SETS mampu meningkatkan keterampilan berpikir kritis siswa. Indikator keterampilan berpikir kritis tertinggi di kelas eksperimen adalah membuat induksi dan mempertimbangkan hasil induksi dan indikator terendah adalah mengobservasi dan mempertimbangkan hasil observasi.

This study aims to determine the effect of applying blended learning on static electricity material to students' critical thinking abilities. This study used a quasi-experimental research method with a pretest-posttest control group design. This study uses Mann Whitney U-Test data analysis techniques so that the data can be said to have a significant difference to the critical thinking skills of the experimental class using blended learning and the control class using direct (conventional) learning. The conclusion of this study is that there is an effect after learning in blended learning which is characterized by differences in N-gain mean values that are significant between the experimental class and the control class, where the N-gain value in the experimental class is higher than the average N- gain in the control class.

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 study investigates the effectiveness of the blended learning model in improving critical thinking and communication skills of students at university. This is a quasi-experimental study with a non-equivalent control group design involving one experimental group and one control group. The research population comprised students sitting in the Entrepreneurship class at the Department of Electronic Engineering Education, who were selected purposively. The data were about critical thinking skills that were gathered using a test, while the data about communication skills were obtained through observations. The data were analysed using a paired sample t-test and an independent sample t-test. The findings show that: (1) the implementation of the blended learning model effectively increases the critical thinking skills; (2) the use of the blended learning model effectively improves students’ communication skills and (3) according to the independent sample t-test, students’ critical thinking skills and communication skills in the experimental class had a significant difference from those in the control class.   Keywords: Blended learning model, critical thinking skills, communication skills.
