Abstract

This research investigates the impact of the Contextual Teaching and Learning (CTL) model on critical thinking abilities and student character in the reaction rate topic at SMA Negeri 3 Gorontalo Utara. This research employs a quantitative methodology with a near-experimental design, specifically employing a one-group pre-test and post-test design. Data were gathered through questionnaires and tests. The study's population consisted of grade XI students at SMA Negeri 3 Gorontalo Utara throughout the opening term of the academic cycle for 2024-2025. A total sampling method was used, selecting 50 students from two classes who enrolled in chemistry specialization. The findings indicate that the application of the CTL model led to an improvement in critical thinking skills, with the experimental class showing a mean pre-test result of 37.56% and a post-test result of 84.22%, whereas the replication group recorded pre-test and post-test averages of 37.33% and 83.89%, respectively. As for character growth, the experimental group displayed an average score of 80.13%, while the replication group showed 79.90%. Both classes demonstrated significant progress, as shown by the consistency of the results in both groups. The outcomes of the paired sample t-test reveal a noteworthy value of 0.000 < 0.05, prompting the dismissal of H0 and the endorsement of Ha, confirming that the CTL model positively affects critical thinking skills and student character in reaction rate material.

Abstract

This study aims to analyze students’ conceptual understanding of hydrocarbons through a literature review utilizing the Three-Tier Multiple Choice Diagnostic Instrument. Hydrocarbons are a fundamental topic in chemistry education that often leads to student misconceptions. The three-tier diagnostic instrument is designed not only to assess students’ cognitive knowledge through correct or incorrect answers but also to explore the reasoning behind their choices, enabling more accurate identification of misconceptions and conceptual understanding. The methodology employed is a literature review examining various scientific sources on the application of this diagnostic tool in teaching hydrocarbon concepts. The findings indicate that the Three-Tier Multiple Choice Diagnostic Instrument is effective in systematically detecting and classifying students’ difficulties and misconceptions. Furthermore, the use of this instrument contributes significantly to developing targeted and data-driven instructional strategies to enhance students’ conceptual mastery in chemistry. The implications of this study highlight the necessity of integrating three-tier diagnostic instruments in the assessment process to support optimal learning outcomes in hydrocarbon material.

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

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.
