Abstract

Education on the dangers of using food additives is an effort to enhance the public's understanding of the risks associated with consuming foods containing additives. The increased consumption of additives correlates with the rising intake of processed foods. The objective of this community engagement initiative is to raise awareness among the public regarding the potential hazards associated with the use of food additives. The methods employed include lecture-style presentations and discussions. The community gains an understanding of various types of additives commonly used in food, with an emphasis on their benefits, such as prolonging the shelf life of food. However, the education also highlights associated risks, including potential adverse effects on health like allergies, digestive disorders, and long-term effects that are not fully understood. The activities took place in the village of Hutadaa in Gorontalo Regency, with a total of 18 participants. The participants were enthusiastic, and increased knowledge was evident through the questions raised during the session.

Abstract

This study aimed to analyze the effect of implementing a STEM-based guided inquiry learning model on students’ critical thinking skills regarding reaction rates. Despite the increasing emphasis on critical thinking in science education, limited research has examined how integrated STEM-based instructional models affect students’ higher-order thinking skills specifically in abstract and conceptually demanding topics like reaction rates. This study addresses that gap by evaluating the effectiveness of such a model in a real classroom setting. The research employed a quasi-experimental method with a non-equivalent control group design. A total of sixty students from SMA Negeri 1 Bolaang-Uki were selected through purposive sampling. The research instrument consisted of ten essay questions covering critical thinking indicators, validated with a Cronbach’s Alpha of 0.706, indicating high reliability. The findings showed that the implementation of the STEM-based guided inquiry model significantly improved students’ critical thinking skills. The average pretest score of 10.68% increased to 31.40% in the posttest. Hypothesis testing using an independent-sample t-test resulted in a significance value of 0.000 (< 0.05) with t₍count₎ > t₍table₎ (29.709 > 1.671). Therefore, this study confirms that the STEM-based guided inquiry model is effective in enhancing students’ critical thinking skills in learning reaction rate concepts

Abstract

This study aimed to evaluate the effectiveness of a maritime-based e-module contextualized to Teluk Tomini in improving students’ scientific literacy on the topic of reaction rates at SMA Negeri 1 Suwawa. A quasi-experimental method employing a posttest-only control group design was utilized. The study involved an experimental group, which was instructed using the maritime-based e-module, and a control group, which received instruction through a conventional e-module. The findings indicate that students who learned using the Tomini Bay maritime-based e-module demonstrated significantly higher levels of scientific literacy compared to those who were taught using the conventional approach. The mean scientific literacy score of the experimental group reached 22.26, substantially exceeding that of the control group, which obtained a mean score of 11.56. Statistical analysis using One-Way ANOVA confirmed a significant difference between the two groups. The study concludes that the implementation of a maritime-based e-module is effective in enhancing students’ scientific literacy, increasing student engagement, and facilitating the comprehension of abstract concepts such as reaction rates. Furthermore, the module promotes awareness of local environmental sustainability, thereby integrating contextual relevance with scientific understanding.

Abstract

This study examined the effectiveness of the Process Oriented Guided Inquiry Learning (POGIL) approach in improving students’ conceptual understanding of reaction-rate concepts and investigated whether scientific reasoning skills moderate the effect of instructional model in a 2×2 factorial design. Forty-four tenth-grade science students from two intact classes were matched and categorized into high and low scientific reasoning groups. Conceptual understanding was measured using a two-tier diagnostic test, and assumptions for Two-Way ANOVA were verified before analysis. Results indicated a significant main effect of instructional model, with POGIL achieving higher scores than verification-based instruction (F = 20.385, p < 0.001, η² = 0.29). Scientific reasoning also significantly influenced outcomes (F = 7.328, p = 0.010, η² = 0.10). The interaction between instructional model and reasoning was not statistically significant (F = 2.559, p = 0.118), indicating that the interaction effect was not statistically significant in this sample. POGIL is theoretically expected to support integration of macroscopic, submicroscopic, and symbolic representations through guided inquiry and collaborative scaffolding. Limitations include the small sample size and quasi-experimental design. These findings highlight the potential of guided inquiry-oriented instruction to enhance conceptual understanding while emphasizing the role of reasoning skills, with cautious interpretation of non-significant interactions.

Abstract

Developing students’ critical thinking skills remains a major challenge in chemistry education, particularly in thermochemistry, which requires conceptual, symbolic, and quantitative reasoning. While STEM-integrated problem-based learning (PBL–STEM) has gained increasing attention, limited studies have examined how this instructional approach aligns with the cognitive structure of critical thinking. This study investigated the effect of the PBL–STEM model on students’ critical thinking skills in thermochemistry. A quasi-experimental design involving 64 tenth-grade students was employed. Participants were selected using purposive sampling and assigned to an experimental group and a control group. Critical thinking skills were measured using a 20-item essay test based on Facione’s framework. The instrument demonstrated high reliability (Cronbach’s α = 0.915) and strong content validity (CVI = 0.93). Data were analyzed using an independent-samples t-test. Results showed a significant difference between groups (t = 4.997, p < 0.05), with the experimental group achieving higher mean scores (M = 80.80) than the control group (M = 65.38). The effect size (Cohen’s d = 1.25) indicates a large instructional impact. These findings suggest that STEM-integrated PBL provides a cognitively aligned framework for fostering critical thinking in chemistry learning.
