Abstract

This study aims to analyze the effect of the Contextual Teaching And Learning (CTL) approach to the Critical Thinking Ability of Class VII MTs Students. Uswatun Hasanah Cempaka Putih on Environmental Pollution Materials. This study uses an experimental research method with True experimental form and nonequivalent control group design. The population in this study were all students of Class VII MTs. Uswatun Hasanah Cempaka Putih, amounting to 65 students. This study also uses a sampling technique that is using nonprobability sampling with the type of Purposive Sampling. Data collection techniques using direct observation and measurement techniques. The research instrument used was a written test with multiple choice tests and using critical thinking indicators from Ennis. Based on the results of data analysis of students' critical thinking skills, the average post-test scores in the experimental class and the control class were 66,333 and 56,774. T-test results obtained t-count = 2.538 and t-table = 2.001 (α = 5%; db = 59). Because t-count (2,538)> t-table (2,001), it means that Ha is accepted and H0 is rejected. The effect size is 0.638 with moderate criteria. The conclusion of this study is that there is a moderate effect on Contextual Teaching and Learning (CTL) learning and learning approaches to the Critical Thinking Ability of Class VII MTs Uswatun Hasanah Cempaka Putih with medium criteria.

Abstract

The purpose of this research was to analyze students problem-solving skills related to the topic of Archimedes' law which is taught using a problem - based learning model. The research subjects were 36 students of SMK Bakti Kencana class. The research model that used for this research was mixed methods. The results of this study was indicate that the students' problem-solving abilities have increased significantly, namely the N-gain average score of 0.70 is in the medium category, and the effect size is 5.08 (very strong category). So it can be concluded that the students' problem solving abilities have changed very well, namely at the stage of defining the problem: problem schema, understanding casual relationships in problems, arguing to learn problem solving, and analogizing problems.

Abstract

The purpose of this study was to determine the effect of SETS (Science, Environment, Technology, Society) learning on the mastery of students' critical thinking abilities using tests and observations. The type of this research was a quasi experiment. This research used an experimental class and control class. The sampling technique used was cluster sampling. To determine the differences in the mastery of critical thinking skills in the control class and the experimental class, the t-test was carried out with the Polled Variance formula. The analysis results show t count = 10.1332 while t table = 1.9908 with a significant level of 0.05 so that t count> t table. H1 is accepted, it can be the influence of the SETS (Science, Environment, Technology and Society) learning method on critical thinking skills. So that can be conclude that there is an influence of the SETS learning method in improving students' critical thinking skills.
