Abstract

The module is one of the teaching materials that is arranged as a whole and systematically. Modules based on learning models can change learning patterns from teacher center to student center. One of the learning models developed specifically for subject matter in the field of science is 5E instructional. The 5E Instructional Model consists of 5 stages namely engagement, exploration, explanation, elaboration and evaluation. The purpose of this study was to develop an instructional module based on 5E chemical laws to improve the process skills of science students. The type of research conducted is research & development (R&D) with the ADDIE development model. The results obtained for the validity of the construct and content were 0.89 and 0.91 with the valid category. Based on the results of the teacher and student response questionnaires, an average practicality score of 86.96% and 86.10% was obtained in the very practical category. The results of the effectiveness test conducted in the experimental and control classes showed that the N-gain value for the experimental class was higher than the control class, namely 0.84 and 0.79. Based on the results of the t-test on student learning outcomes, it was found that tt < th means that the learning outcomes of classes using the 5E instructional module were significantly higher compared to classes that did not use the 5E instructional module. Therefore, it can be said that the 5E-based basic chemistry law module is valid, practical, and effective. The effectiveness of the developed module is seen from the learning outcomes of students and science process skills, so that this module can already be used in the learning process.

Abstract

Merdeka curriculum emphasizes the ability of students to understand and apply their concepts to solve contextual problems. This research aimed to determine the validity, practicality, and effectivity of buffer solution students’ worksheet based on problem based learning with etnochemistry on students’ science literacy ability. The development model used in this research is 4-D. buffer solution students’ worksheet was validated by 3 chemistry lectures and 2 chemistry teachers. Practicality tests were carried out by 3 chemistry teachers and 32 students. Then, the level of effectiveness of buffer solution students' worksheet is known through the N-gain test. The validity test was analyzed by using aiken's v derived formula consisting the validity of the content and construct which was 0.91 and 0.90 with category valid. The results of the practicality of teachers and students was 88.80 and 87.75 with higher category. Analysis of the n-gain value obtained the results of the value of g = 0.86 in the high category. Then the date analyzed with quantitative method by using hypotheses testing, determined that the research hypothesis was accepted. This result confirmed that buffer solution students’ worksheet based on problem based learning with ethnochemistry was valid, practical, and effective to improving students’ science literacy ability significantly.

Abstract

This study aims to produce an acid-base module based on ethnochemical problem-based learning to improve students' scientific literacy skills, analyze the validity and practicality of the module and analyze the effectiveness of the acid-base module based on ethnochemical problem-based learning to improve students' scientific literacy skills. The type of research used is Research and Development (R&D) with a 4-D development model. The 4-D development model consists of 4 stages of development, namely define, design, develop and disseminate. The research instruments used are interview sheets, questionnaires, validation instruments, practicality instruments and effectiveness instruments. The validity test uses the Aiken's V formula. The results of the construct and content validity tests were 0.88 and 0.89 with a valid category. The results of the module practicality test carried out by teachers and students were 91.25% and 90.65% with a very practical category. The effectiveness test of the module was carried out using the N-Gain test and obtained a result of 0.71 in the high category. The results of the study indicate that a valid, practical and effective acid-base module based on ethnochemical problem-based learning has been obtained in improving students' scientific literacy skills.
