Abstract

This study aims to identify differences in student learning outcomes between those who receive learning using the Quantum Teaching model and those who receive conventional learning on the material of reaction rates at SMA Negeri 1 Tapa. This study is a quantitative study that applies a quasi-experimental method through a control group design with pretest and posttest. The results of the study indicate that after the application of the Quantum Teaching learning model in the experimental class and the use of the conventional learning model in the control class, there was an increase in student learning outcomes. The average pretest score of the experimental class was 34.37 and the posttest score reached 77.31, while for the control class, the average pretest score was 39 and the posttest score was 58.21. It can be seen that both groups of classes showed significant progress , which can be seen from the higher scores in the experimental group when compared to the control group . The hypothesis was tested through a mean test ( t- test ). The results of the Paired Sample t-test in the experimental group showed a significant difference between the pretest and posttest results, with a significance value of 0.000 , which is much lower than the limit of α = 0.05. This study shows that learning using the Quantum Teaching model has a positive impact on improving students' conceptual understanding.

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

This study focuses on the effect of applying the Contextual Teaching and Learning (CTL) model in the topic of reaction rate on the ability to think critically and the formation of character values of students in geographically remote areas (remote areas). This approach is designed to strengthen learners' understanding of scientific concepts in a relevant and contextual manner, by connecting them to the dynamics of real life - both in the personal, social and cultural domains. Thus, learners have the opportunity to build conceptual insights and adaptive skills independently. In addition, this real situation-based method contributes to fostering character values such as responsibility, discipline, innovation, curiosity, as well as social interaction skills and effective communication during the learning process. The literature review was conducted by collecting scientific publications released between 2018 and 2025. The findings of this review confirmed that the CTL approach has a real positive impact in honing critical thinking skills and fostering learners' character that supports their academic achievement. Therefore, it can be concluded that CTL is an efficient and relevant pedagogical method to be applied in teaching high school chemistry.
