Abstract

This research aims to determine the effect of the cooperative learning model with Baurus pattern problem solving method on the collaborative skills of students of SMP Kristen 2 (Christian Junior High School 2) on the subject of Indonesian Ecology and Biodiversity. The method used in this research is quantitative descriptive (quasi-experimental). The research subjects were students of class VII-D (control class) and class VII-C (experimental class) at SMP Kristen 2 Salatiga. Data analysis is carried out using inferential statistics with the Wilcoxon test, Man Whitney, and N-Gain score. The results of the validity and reliability test on the research instrument show that the instrument is valid and reliable. Based on the results of observations, the syntax of the cooperative learning model with Baurus pattern problem solving method is included in the fully implemented category with a score of 4.9. Students also give positive response with a score of 0.9. The results of the Wilcoxon test show that the cooperative learning model with Baurus problem solving method has an effect on collaborative skills with a p-value of 0.00 α 0.05 and an N-Gain score reaching 0.7 (high). The results of the Man Whitney test show a p-value of 0.00α0.05, which means there is a significant difference in influence between the cooperative learning model with Baurus pattern problem solving method and STAD cooperative learning model.

Abstract

The objectives of this study were 1) to improve student's critical thinking skills through Problem Based Learning (PBL) with a Lesson Study approach on respiratory system material; 2) to analyze students' critical thinking skills in studying the respiratory system; 3) to determine the differences in the effect of the PBL-LS and PBL learning models on critical thinking skills in the material of the respiratory system. This study used a quasi-experimental design. The subjects in this study were XI MIPA 1 and XI MIPA 2 grade SMA Negeri 1 Salatiga. This research was conducted in the even semester of the 2022/2023 Academic Year from September 2023 to May 2022. The data analysis technique used is quantitative descriptive analysis. Based on the research results, it is known that there is an influence of the PBL-LS learning model on critical thinking skills (p-value 0.05) with an N-Gain of 0.5 (moderate). The results of the analysis of each indicator of critical thinking skills showed from that the lowest indicator to the highest indicator of critical thinking skills was found from the inference (65,8); reason (69,4); clarity (69,8); focus (72,8); overview (75,0); situation (79,7). In addition, it was also found that there was a difference in the effect of the PBL-LS and PBL learning models on critical thinking skills (p-value 0.05).

Abstract

This research aims to determine the profile of critical thinking skills of Class VII middle school students on ecology and biodiversity material using quantitative descriptive research with data collection techniques using tests, analysis using a quantitative approach consisting of empirical validity, reliability, differentiation, level of difficulty and data analysis scores, and research design using pretest - posttest design, data collection techniques using critical thinking questionnaires, data analysis techniques by looking at interpretation results and N - Gain. The research results of students' critical thinking skills at the beginning of the test (pre-test) reached an average score of 47.49, while the average score of students at the end of learning (posttest) reached 64.09. Based on the interpretation results, it shows that the pre-test results are in the poor category with a total of 63 students (100%), while the post-test scores in the interpretation results show that there are 17 students (26.98%) in the sufficient category and 46 students (73.02%) in the insufficient category. So it can be said that there may be many factors that cause students to lack enthusiasm in science subjects on ecology and biodiversity, including the lack of variety in the methods used in teaching.
