Abstract

Effective teaching strategies are critical in enhancing students' attitudes toward chemistry and formal reasoning abilities, particularly for complex topics like acids and bases. Case-based learning has emerged as a promising alternative to traditional scientific learning methods. This study aims to compare the differences in attitudes toward chemistry and formal reasoning skills between students exposed to case-based learning and those undergoing scientific learning on acids and bases. A quasi-experimental design with a posttest-only control group was applied to 122 student of 11th grade science students in Yogyakarta, selected using simple random sampling. Data were collected through case-based essay questions and attitude questionnaires. Multivariate analysis (Hotelling Trace) assessed the differences between groups. The analysis revealed a significant difference (p = 0.000 < 0.05) in attitudes and formal reasoning skills between the two groups. Students in the case-based learning group demonstrated significantly better attitudes toward chemistry compared to those in the scientific learning group. These findings highlight the potential of case-based learning to enhance students’ engagement and reasoning skills in chemistry. By integrating case-based approaches into acid-base learning, teachers can adopt alternative methods to improve student outcomes. This study underscores the importance of diversifying teaching strategies to address the challenges of complex scientific topics effectively.

Abstract

Purpose-This study aims to develop an evaluation tool to measure students' critical thinking skills, specifically integrating the process of making batik local wisdom into science learning.Methodology-This research uses the Research and Development (R&D) method with the 4D model, which includes four main stages: Define, Design, Develop, and Disseminate. A random sampling technique is used, which involves160 students.Findings-The instrument consists of 20 questions validated with Aiken's V values ranging from 0.93 to 0.97, indicating excellent content validity. All question items are declared fit based on the Rasch model analysis. The instrument had an item reliability of 0.91 and a respondent reliability of 0.73. Analysis of the distribution of threshold values (b) shows that most questions are in the medium category.Contribution-This research integrates local wisdom, namely batik, into assessing critical thinking skills, an approach rarely encountered in previous research. In conclusion, the developed instrument effectively measures students' critical thinking skills. It can be used to measure them, especially in the context of learning about batik as part of local wisdom.

Abstract

Critical thinking skills are essential for students to navigate future challenges and comprehend complex issues. However, many students have not been trained to think critically in the context of science, particularly because the learning process still emphasises theoretical learning over active exploration. This study aims to analyse the effectiveness of using mini solar panel teaching aids in conjunction with a guided inquiry model in improving the critical thinking skills of grade VIII junior high school students. This study was a Pre-Experiment with a one-group pretest-posttest Design. The study population consisted of all grade VIII junior high school students, with a sample of class VIII B comprising 31 students. The results showed that mini solar panel teaching aids, combined with a guided inquiry model, were effective in improving students' critical thinking skills, with an average increase in the N-Gain score of 0.63 in the moderate category. Second, there was a significant difference in the average score of students' critical thinking skills before and after the implementation of the teaching aids, with an average pretest score of 5.56 and a post-test score of 11.16. Third, the implementation of mini solar panel teaching aids using a guided inquiry approach had a significant impact on the development of students' critical thinking skills. This study demonstrates that the use of mini solar panel teaching aids in conjunction with a guided inquiry model can be an effective learning method for enhancing students' critical thinking skills in science learning.
