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

The purpose of writing this article is to provide an overview of the learning process of blended learning and studies that examine the effect of blended learning models on learning outcomes. Where this can be used as a reference in the use of blended learning models in learning science. The method used is the method of meta-analysis which was carried out through studies in a number of international and national journals in the last 3 years. Sampling using a homogeneous sampling strategy. The samples in this study were 30 international and national journals that discussed the blended learning model, which in this case focused more on the effect of the blended learning model on student learning outcomes. Data were obtained using the results summary instrument and data analysis. The results of the research show that from several studies reviewed in the last 3 years, it is stated that the blended learning model is generally effective in improving student learning outcomes, especially in learning Natural Sciences. Therefore this blended learning model can be used as a learning model that can be used in science lessons at school.

Abstract

This meta-analysis investigates the effectiveness of the Problem-Based Learning (PBL) model in enhancing students' critical thinking and problem-solving skills in science education. A total of 42 peer-reviewed articles published between 2020 and 2024 were analyzed, covering diverse educational levels and scientific disciplines. The analysis revealed a large average effect size (ES = 0.798; 95% CI: 0.782–0.813), indicating a strong positive impact of PBL. The low standard error (SE = 0.043–0.060) reflects high estimation precision. Statistical tests, including funnel plot symmetry, Trim-and-Fill analysis (p = 0.991), and Egger’s regression test (p = 0.947), confirm the absence of significant publication bias. Moreover, residual heterogeneity was minimal (τ² = 0.000), validating the appropriateness of the fixed-effects model. These findings provide robust empirical evidence that PBL is consistently effective across various contexts in improving students’ 21st-century competencies. The study offers meaningful implications for educators and policymakers in designing science learning strategies that foster higher-order thinking skills.

Abstract

This research is motivated by the development of LKPD (Student Worksheet) for enhancing critical thinking skills of elementary school students. The LKPD used has not yet captured the students' attention. The LKPD has not been able to improve students' learning motivation because it does not align with their learning styles. LKPD serves as teaching material used by teachers to facilitate the delivery of content and achieve learning objectives. This study aims to develop LKPD and assess its validity using the Inquiry model to improve critical thinking skills in Science education about the conservation of natural resources in the 4th-grade class. The type of research used is research and development (R&D), employing the 4-D model. This model consists of four development stages: define, design, development, and dissemination. Based on the results of the validation of LKPD using the Inquiry model to enhance critical thinking skills, the LKPD is deemed feasible for use. The material aspect validation result was 85.41% (valid), the design aspect validation result was 86.53% (valid), and the language aspect validation result was 94.44% (very valid). Therefore, the LKPD using the Inquiry model to improve critical thinking skills is valid.

Abstract

This research aims to develop a chemistry learning e-module for acids and bases based on guided discovery learning, incorporating elements of ethnoscience to improve students' literacy and numeracy. The guided discovery learning approach was chosen to encourage students to actively construct knowledge through guidance, while the integration of ethnoscience aims to link chemistry concepts with local wisdom to increase student relevance and understanding. The research method used was Research and Development (R&D) with the 4D development model (Define, Design, Develop, Disseminate). The research instruments included an expert validation sheet, a student response questionnaire, and literacy and numeracy tests. The validation results indicated that the e-module was highly feasible in terms of content, presentation, and language. A limited trial demonstrated significant improvements in students' literacy and numeracy skills after using the e-module. Therefore, this e-module is effective as an alternative learning medium for contextual and meaningful chemistry learning.
