Abstract

The PBL-STEAM approach based on Mandai local wisdom is designed to encourage students' activeness and curiosity in solving real problems by integrating Mandai local wisdom values. This study aims to determine the effect of PBL-STEAM based on Mandai local wisdom on students' critical thinking skills (CTS) on osmosis pressure material. The research used a quasi-experimental method with a non-randomized pretest-posttest control group design. The study population was class XII students of SMA Negeri 2 Samarinda in the 2024/2025 school year, with a research sample of class XII-C as the experimental class and XII-D as the control class, totaling 68 students selected using purposive sampling. Data were collected through CTS tests, teacher and student activity observation sheets, and student response questionnaires. The average score for CTS of experimental class students was 79.56, with a high category, and the control class's score was 70.38, with a medium category. The results of the independent samples t-test showed a sig value. (2-tailed) 0.000 0.05, indicating a significant effect of PBL-STEAM based on Mandai local wisdom on students' CTS. The paired samples t-test results showed a sig value. (2-tailed) 0.000 0.05, indicating an increase in the learning outcomes of experimental class students. Teacher and student activities in the experimental class in learning each reached 100% of the very applied category and 90.82% of the outstanding category. The average student response to PBL-STEAM learning was 85.47%, which is included in the very good category, which proves that this learning based on Mandai local wisdom is able to improve students' CTS

Abstract

Low student learning outcomes are often caused by limited student participation and the use of teacher-centered learning approaches. This study aims to determine the effectiveness of the Think Pair Square (TPSq) cooperative learning model assisted by stick media in improving student learning outcomes, particularly in the topic of chemical compound nomenclature. The research used a pre-experimental one-group pretest-posttest design with participants from class X-10 students at a senior high school (N=32). Learning outcomes were measured using tests given before and after the implementation of the model. Data were analyzed using a non-parametric Wilcoxon test. The results indicated a significant improvement in student learning outcomes, with an N-Gain score of 0.71 (high category) and an effect size of 3.85 (very strong category). The TPSq model, supported by stick media, encouraged students to think, discuss, and share ideas actively, leading to a deeper understanding of the material. In conclusion, the stick media-assisted TPSq learning model is effective in enhancing student learning outcomes in chemical compound nomenclature.

Abstract

Science process skills (SPS) are essential competencies in chemistry learning that support development of scientific thinking and evidence-based problem solving. This study aimed to analyze differences in students' SPS based on gender in chemistry learning at a public senior high schools in Samarinda. The study used a retrospective comparative quantitative approach. The SPS data were collected by using documentation technique involving 65 SPS of eleventh grade students (31 males and 34 females) who programmed chemistry subject. SPS data were analyzed descriptively and inferentially using the Mann-Whitney U test (α = 0.05). The results showed that there was no significant difference in overall SPS between male and female students (p = 0.333) and in most indicators (p > 0.05), except for the observation indicator (p = 0.004), with female students having a slightly higher descriptive mean. These findings confirm that mastery of SPS is more influenced by the quality of the learning process than by gender factors, thus contributing empirically to the application of inclusive science learning oriented towards scientific activities.

Abstract

Purpose of the study: This study aims to design and validate a project-based organic chemistry practicum module that integrates a contextual approach, which is designed to facilitate students’ conceptual understanding, practical skills, engagement, learning motivation, and overall learning experience during laboratory practicum activities. Methodology: This study employed the Research and Development (R&D) method utilizing the ADDIE model specifically for the Analysis, Design, and Development stages. It represents early development phase focused on design and expert validation. Data were collected through interviews and questionnaires. Module validation carried out by subject matter and media validators using Likert scale instruments and Gregory matrix calculations to ensure validity. Main Findings: This study’s project-based, contextually integrated organic chemistry practicum module operationalizes PjBL through structured stages. Contextual learning integrates authentic phenomena with real-world applications. Validation involved two subject matter and two media validators, yielding Gregory coefficients of 1.00 for both. The module is highly valid, and future studies should test its effectiveness and practicality in enhancing conceptual understanding or 21st-century 4C skills. Novelty/Originality of this study: This study developed an organic chemistry practicum module that systematically integrates contextual phenomena across all PjBL phases. Unlike previous PjBL modules lacking contextual integration or conventional recipe-style modules with limited learning impact. This module addresses gaps in conceptual reasoning, contextual relevance, and competency, while reducing procedural learning and enhancing conceptual understanding, practical skills, 21st-century skills, and integrated science learning.

Abstract

This research is driven by the instructional saturation and passive learning environment observed in green chemistry education at SMAN 8 Samarinda. The study aims to conduct a needs analysis and design an interactive learning medium called the Green Solver card game to increase student engagement and conceptual understanding. Using the Research and Development (R&D) approach with the ADDIE model, this research is specifically limited to the analysis and design stages. The subjects involved in this preliminary study were 1 chemistry teacher and 189 tenth-grade students as the primary data sources. The analysis stage, conducted through interviews and questionnaires, revealed that 76.2% of students found existing static media uninteresting, while 92.1% expressed a strong preference for the integration of game-based learning. In the design stage, the Green Solver card game was developed by adapting the "Truth or Dare" social mechanism into two strategic components: Theory cards and Action cards. Theory cards serve as retrieval practice tools to strengthen conceptual memory, whereas Action cards incorporate gamified challenges and environmental problem-solving tasks to alleviate learning anxiety and promote social collaboration. The resulting design includes a comprehensive guidebook, a tiered scoring system (5-40 points), and visual elements optimized for cognitive processing through dual coding. This study successfully produced a prototype blueprint that offers a holistic solution to transform classroom dynamics from passive to active learning.
