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

Chemical numeracy is essential for understanding quantitative concepts in chemistry; however, there are indications of achievement gaps between male and female students. This study aims to analyze the influence of gender on students' numeracy skills when implementing the Problem-Based Learning (PBL) model. This study employed a quasi-experimental design with a nonequivalent control group. The study population consisted of Phase F students at three high schools in West Sumatra, Indonesia. The sample comprised 188 students selected through purposive sampling based on initial ability equivalence. The research sample came from three schools, each serving as a research context for different topics: salt hydrolysis (experimental class = 33; control class = 30), reaction rates (experimental class = 35; control class = 35), and chemical equilibrium (experimental class = 26; control class = 29). The research instrument consisted of a chemistry numerical literacy test on reaction rates, chemical equilibrium, and salt hydrolysis, which experts had validated. Instruction in the experimental classes used the PBL model, while the control classes used conventional instruction, as typically implemented in schools. Data were analyzed using the N-gain test, normality test, homogeneity test, and Two-Way ANOVA. Results showed that improvement in numerical literacy in chemistry was greater in PBL classes than in control classes. Statistical analysis indicated that the PBL model had a significant effect on improving numerical literacy in chemistry. Gender was significant in only one school, and the interaction between the learning model and gender was also significant there, suggesting that the model's effectiveness may vary by context. These findings indicate that PBL is effective in enhancing students' numerical literacy in chemistry and imply that chemistry instruction should be designed around problem-solving approaches to develop quantitative reasoning and a contextual understanding of chemical concepts.
