Abstract

This study aims to develop problem-based learning student worksheets integrated with ethnoscience on acid-base materials that are valid and practical. This research uses a development research method (Research and Development) with a 4-D model. The data of this study were collected through validity sheets completed by 4 validators, namely 2 chemistry lecturers and 2 chemistry teachers, and with a practicality questionnaire sheet completed by 2 chemistry teachers and by 35 students of SMAN 1 Batusangkar as respondents. Data were analyzed using quantitative descriptive method, using Aiken’s V. The result for content validity is 0.88 and construct validity is 0.90 with valid category. The result for teachers practicality is 0.95 and students practicality is 0.82 with practical category. Based on the results of the research that has been conducted, it can be concluded that the development of problem-based learning-based student worksheets integrated with ethnoscience on acid-base material is valid and practical.

Abstract

Acid-base is one of the important materials in chemistry learning. Based on preliminary analysis, it is known that students have not properly understood the concept of acid-base. This study aims to develop an acid-base e-module, analyze its validity, practicality, and effectiveness on critical thinking skills. This research method is development research with the Plomp development model. The e-module was validated by 5 valitadors. The practicality test was conducted on 28 students and 3 teachers. The effectiveness of the e-module is seen from the increase in critical thinking test score from 57 students. Validity and practicality were analyzed using Aiken's V, while effectiveness was analyzed with N-Gain. The results showed that the developed e-module had a validity value of 0.89 with a valid category; a practicality value of 0.87 by students and 0.97 by teachers with a practical category. The effectiveness results show that the e-module has an effect on students' critical thinking skills, as evidenced by the N-Gain score of the experimental class of 0,7 with a fairly effective category while the N-Gain score of the control class is 0,4 with a less effective category. Thus, the developed e-module is declared valid, practical, and effective.

Abstract

The Merdeka Curriculum emphasizes students’ ability to understand and apply their conceptual knowledge to solve contextual problems. This study aims to determine the validity, practicality, and effectiveness of an acid–base module based on problem-based learning integrated with TPACK in improving the learning outcomes of Phase F senior high school (SMA/MA) students. The development model used in this research was the 4-D model. The acid–base module was validated by three chemistry lecturers and two chemistry teachers. The practicality test of the module was conducted by three chemistry teachers and 31 students. The effectiveness of the module in improving learning outcomes was analyzed using the N-gain test. The validity test was analyzed using Aiken’s V, which consisted of content and construct validity, yielding results of 0.89 and 0.91, respectively, both categorized as valid. The practicality results from teachers and students were 98.61% and 86.87%, respectively, both in the high category. The N-gain analysis resulted in a value of g = 0.79, categorized as high. Based on the hypothesis test, the calculated t-value was greater than the critical t-value. These findings confirm that the developed acid–base module based on problem-based learning integrated with TPACK is valid, practical, and effective for significantly enhancing students’ learning outcomes.
