Abstract

Indonesian education has undergone a curriculum change in the form of the "Merdeka Curriculum," where one of the challenges faced is the limited availability of teaching materials, which affects the learning process of students. Another challenge Indonesia faces is the low level of scientific literacy among students. Therefore, it is necessary to develop teaching materials in the form of an e-module based on socio-scientific issues to improve students' scientific literacy. The purpose of this study is to determine the feasibility, student responses, and effectiveness of the e-module, as well as to analyze the improvement in students' scientific literacy. This type of research is Research and Development (R&D) using the 4D development model, namely define, design, develop, and disseminate, to produce a product that is suitable for use. The developed e-module was validated by five experts and achieved a high validity level (90.3% for content and 90% for media). Student responses to the e-module showed very good results, with an average score of 60.85 for class X-3 and 61.59 for class X-4. The N-gain test showed significant effectiveness, with a score of 0.735 (high category) for class X-3 and 0.677 (medium category) for class X-4. The results of this study indicate that the socio-scientific issue-based e-module is effective in improving students' scientific literacy on the topic of global warming.

Abstract

Science, Technology, Engineering, and Mathematics (STEM) education has been demonstrated to effectively enhance the quality of learning. However, the implementation of PBL-STEM in chemistry instruction, particularly on the topic of basic chemical laws, has not been optimally applied. This study aims to analyze the feasibility, effectiveness, and students’ responses toward the use of an electronic student worksheet (E-LKPD). The research employed a Research and Development (R&D) methodology using the 4D model, which includes the stages of Define, Design, Develop, and Disseminate. The subjects consisted of 33 tenth-grade students at SMA N 3 Semarang. Data analysis focused on the feasibility, effectiveness, and student feedback. The findings revealed that the PBL-STEM E-LKPD product was deemed valid by both content and media experts, indicating its suitability for educational use. The effectiveness of the E-LKPD was supported by an average N-gain score categorized as moderately effective. Significant improvements in N-gain scores were observed from pretest to posttest across all student groups. These results confirm that the integration of PBL-STEM E-LKPD with differentiated instruction is effective in improving students’ learning outcomes. Furthermore, positive student responses during the implementation of the E-LKPD in classroom settings reinforce its educational value.

Abstract

Chemistry learning on acid-base material needs to be associated with the local cultural context to make it more meaningful for students. This study aims to determine the effect of problem-based learning with the CRT approach on the understanding of acid-base concepts. One of the implementations is done through the activity of identifying pH in batik coloring waste as part of the local culture around SMA Negeri 1 Juwana. The research used a quasi-experimental design with a Nonequivalent Control Group Design model. The research subjects were grade XI students, with grade XI-4 as the experimental class that received treatment in the form of problem-based learning with the CRT approach, and grade XI-5 as the control class with problem-based learning without the CRT approach. The results showed that problem-based learning with the CRT approach had a significant effect on the understanding of the acid-base concept. This is demonstrated by the results of statistical tests that show a significant difference in concept understanding between the experimental and control classes. The influence of problem-based learning with the CRT approach, based on the effect size test value, is 0.778 (medium category). Based on this, the CRT approach in the PBL model is proven to have an effective impact on students' understanding of the acid-base concept.

Abstract

Education is one aspect that needs to be improved in building quality Human Resources (HR). Life in the 21st century requires important skills that must be mastered by everyone, especially students, in order to face existing challenges. Numeracy literacy is part of the basic literacy in 21st-century skills that must be possessed. This study aims to develop a PBL-based chemistry learning module to equip students with numeracy literacy skills on the topic of colligative properties of solutions. The difference lies in the content of the developed module, the material, and the abilities studied, where no previous similar research has examined the development of a PBL-based chemistry learning module to equip students with numeracy literacy skills on the topic of colligative properties of solutions. In this module, PBL syntax is used as a guide in the implementation of learning (material descriptions, case studies, and formative tests of numeracy literacy), and numeracy literacy becomes a reference for the content to be included in the module. The method used in this study is the Research and Development (R&D) method. The development research conducted refers to the 4D model according to Thiagarajan, which consists of Define, Design, Development, and Dissemination. A small-scale trial involved 8 students from class XII MIPA with the criteria of having studied the colligative properties of solutions. A large-scale trial involved 36 students of class XII-E as the experimental class and 36 students of class XII-D as the control class, selected using a purposive sampling technique with consideration from the teacher. The results are: 1) the module is declared feasible with the results of media and material validity of 100% (very valid) and the results of readability and implementation getting a percentage of 92% (very good); 2) the module is declared quite effective with classical learning completion in class XII-E of 50%; and 3) the module received a positive response from teachers and students with a teacher response value of 93% and a student response value of 78%. Based on these results, it can be concluded that the PBL-based chemistry learning module is feasible and quite effective for use in chemistry learning, especially the colligative properties of solutions.
