Abstract

This research is a development researchs. The aim is to produce a physics teaching module oriented to a scientific approach. This teaching module is used to improve students' science process skills. The subjects of the research trial were 34 students of class X of SMAN 13 Makassar. The development model of the physics teaching module oriented to a scientific approach is a 4-D instructional model consisting of define, design, development, dissemination. The research instrument used a validation sheet, a practitioner assessment questionnaire, and a science process skills test instrument. Based on the results of the data analysis, the following conclusions were obtained: the physics teaching module oriented to a scientific approach was declared valid and feasible to use with an integrated scientific approach learning activity structure and a collection of questions according to the science process skills indicators; the physics teaching module oriented to a scientific approach reviewed from the assessment of practitioners, namely physics subject teachers, was in the very good category; the effectiveness of the physics teaching module oriented to a scientific approach reviewed from students' science process skills using the N-Gain score was in the effective category. This can be interpreted that the physics teaching module oriented to a scientific approach that was developed is effective in improving students' science process skills.

Abstract

A research on the development of a Guided Inquiry-Based Learning Module for Students of MAS Ummul Mukminin 'Aisyiyah in South Sulawesi Region has been conducted. This study aims to: produce a guided inquiry-based learning module to improve students' science process skills theoretically; produce a guided inquiry-based learning module to improve students' science process skills empirically; describe the effectiveness of using a guided inquiry-based learning module to improve students' science process skills. The research method used is the Research and Development (R&D) method with the 4 D model. The results of the study indicate that the guided inquiry-based learning module developed based on theoretical and empirical validity is recommended for use. The results of the analysis of practitioner responses to the guided inquiry-based learning module developed, obtained an average score of 131.67 which indicates positive criteria. The effectiveness of the guided inquiry-based learning module is seen from the science process skills using the guided inquiry-based learning module and analyzed for the dependent sample t test. The t table value for db = 30 and a significance level of 0.05 is 2.04 so that the t0 value (calculated) = 3.64 or H0 is rejected.

Abstract

This experimental study aimed to analyze the science process skills and cognitive abilities of students taught through inquiry and hands-on learning. The independent variables were guided inquiry and hands-on learning, while the dependent variables were students' science process skills and cognitive abilities. The results of the descriptive analysis showed that the average KPS score in the guided inquiry group was 19.96 with a standard deviation of 2.01, while the direct learning group was 15.41 with a standard deviation of 4.04. For cognitive abilities, the average score in the guided inquiry group was 18.56 with a standard deviation of 4.18, while the direct learning group was 14.74 with a standard deviation of 3.40. These results indicate a difference in learning outcomes between the two groups, which can be used as a basis for further analysis. Based on the t-test results, there was a significant difference in cognitive abilities between the experimental and control classes (p = 0.001, where p < α = 0.05). Similarly, the difference in science process skills (SPS) was also significant (p = 0.000). These results indicate that guided inquiry learning plays a significant role in improving science process skills and provides a positive contribution to students' cognitive abilities compared to direct learning.

Abstract

This study aims to develop concept elaboration-based physics teaching materials to enhance students' critical thinking skills. The development utilized a 4D (define, design, develop, disseminate) model, which involved validation by experts, practicality assessment by teachers, and field testing with thirty-two Grade XI students. The teaching materials were evaluated for validity, practicality, and effectiveness. The content validity analysis using Aiken's V produced values ranging from 0.77 to 0.82, conveying that the teaching materials were in the valid category. Teachers' assessments showed high practicality, with an average score of 81.5%, while students provided good responses to the teaching materials, with an average of 81%. The effectiveness test, using the Mann–Whitney U test, showed a significant difference between the experimental and control classes (Z = 3.6 > 1.96), with average critical thinking scores of 21 and 17 in the post-test, respectively. These results demonstrate that the concept elaboration-based teaching materials are valid, practical, and effective in improving students' critical thinking skills. The implementation of this approach is expected to enhance students' critical thinking skills within the physics learning experience.

Abstract

This study aims to analyze the content validity of the developed Science Process Skills (SPS)-based physics instructional materials; analyze the responses of educational practitioners regarding the quality and practicality of the materials; and analyze the effect of the developed SPS-based physics instructional materials. The research employed the Research and Development (R&D) method with the 4D model (Define, Design, Develop, and Disseminate). The developed product was validated by three experts, its practicality was assessed by ten physics teachers, and it was tested on 36 tenth-grade students. The instruments used in this study included a validation sheet for the instructional materials, a practitioner response questionnaire, and a validated critical thinking skills test for students. The results showed that the SPS-based physics instructional materials were validated using Aiken’s V index, with an average score of 0.81 for content feasibility, 0.82 for presentation, 0.82 for language, and 0.81 for graphical aspects. The overall average score was 0.82. The hypothesis testing showed that tcount = 8.006 ≥ ttable = 1.994, indicating a significant difference in critical thinking ability between students taught using the SPS-based physics materials and those taught using conventional materials. Based on these findings, the developed SPS-based physics instructional materials are valid according to experts, practical based on teachers’ assessments, positively received, and effective in improving students’ critical thinking skills, thus feasible for implementation in physics learning as a supportive medium to enhance students’ critical thinking abilities.
