Abstract

The principles of chemistry learning emphasize that students study chemical concept in a structure and detailed manner. Until now, chemistry lessons are still a big challenge for teachers, because students often experience difficulties when learning chemical concept such as the concept of stoichiometry. This study aims to determine the level of concept understanding and the percentage of students' concept understanding on stoichiometry material using a five tier diagnostic test. The method used in this research is descriptive qualitative. The results showed: (1) the average level of students' concept understanding is classified in the category of lack of knowledge (LK); (2) the average percentage of students who understand the concept (SC) is 13.0% and the sub-concept with the highest percentage of understanding the concept (SC) is Relative Molecular Mass which is 33.0%. Of the 15 questions tested, question number 1 has the highest percentage of understanding the concept (SC) of 33.0%, while for the other 14 questions the average student is classified in the category of lack of knowledge (LK). It can be concluded that students' concept understanding on stoichiometry material is still classified as very low criteria.

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

Despite the importance of understanding reaction rate concepts in chemistry, students often struggle with abstract content and low engagement in traditional learning settings. Conventional teaching methods tend to emphasize rote memorization, limiting opportunities for critical thinking and problem-solving. This study investigated the influence of ChatGPT-assisted Problem-Based Learning (PBL) on students’ learning outcomes in reaction rate material. A quasi-experimental design with a non-equivalent control group was employed, involving two Class XI groups at SMA Negeri 1 Kabila: XI A as the experimental group (using ChatGPT-assisted PBL) and XI B as the control group (receiving conventional instruction). Learning outcomes were measured using an essay test aligned with cognitive indicators. Results showed greater improvement in the experimental group, with a posttest average of 78.68 compared to 69.23 in the control group. Independent sample t-test analysis revealed a significant difference between groups (p = 0.001 < 0.05), and the N-Gain score indicated a higher improvement category in the experimental class. These findings suggest that integrating ChatGPT into PBL enhances students’ understanding of reaction rate concepts and supports more effective learning, highlighting the potential of AI-assisted strategies in chemistry education.

Abstract

Students’ higher-order thinking skills in chemistry remain low due to the dominance of conventional teaching methods. This study aimed to investigate the effect of the CUPS (Conceptual Understanding Procedures) learning model on students’ higher-order thinking skills in the topic of basic laws of chemistry. Using a quasi-experimental design with a pretest-posttest control group, two classes of 28 students each from SMAN 1 Suwawa were selected as the experimental (CUPS-based learning) and control (conventional learning) groups. Data were analyzed using independent sample t-test. Results showed a greater improvement in the experimental class (pretest = 61, posttest = 79) compared to the control class (pretest = 39, posttest = 64). A significant difference was found between the groups (p = 0.001 < 0.05), leading to the rejection of the null hypothesis. These findings indicate that the CUPS learning model positively enhances students’ higher-order thinking skills, suggesting its potential for improving chemistry education

Abstract

The objective of this research is to investigate the influence of the Project-Based Learning (PjBL) model, when integrated with the STEM approach, on students’ collaborative abilities in the topic of atomic structure. The study is motivated by the persistent issue of low collaboration levels among chemistry learners, particularly when dealing with abstract subject matter. Employing a quantitative methodology with a quasi-experimental design—specifically the Non-Equivalent Control Group Design—the research was conducted with two tenth-grade classes at SMA Negeri 1 Suwawa, designating one as the experimental group and the other as the control group. Data were gathered through observation sheets that measured five aspects of collaboration: cooperation, responsibility, communication, adaptability, and compromise. The findings revealed a notable enhancement in collaborative skills within the experimental class following the application of the STEM-integrated PjBL model. The average final observation score for this group reached 76%, surpassing the control group’s 61%. The N-Gain score for the experimental group fell within the medium category (0.48), whereas the control group’s score was classified as low (0.17). Improvements were recorded across all collaboration indicators. Overall, the results suggest that the STEM-integrated PjBL model is effective in fostering collaboration skills and can be recommended as an alternative instructional approach for other chemistry topics to advance 21st-century skill development.
