Abstract

Conceptual errors or misconceptions are individuals' perceptions that do not align with scientific concepts recognized by experts. This study aims to identify the misconceptions experienced by 11th-grade students on chemical equilibrium, assisted by the Certainty of Response Index (CRI) and utilizing the Discovery Learning model. The research employed an experimental method with a pre-experimental design. The population of this study comprised all 11th-grade students at MAS Syamsuddhuha, with the sample being a single class, namely XI IPA 3. The data collection instrument was a multiple-choice test accompanied by reasoning and a CRI scale, administered after the learning intervention. The analysis results indicated that 43.14% of the sample still experienced misconceptions. The types of misconceptions on chemical equilibrium concepts were as follows: dynamic equilibrium (33.33%), equilibrium constant for concentration (Kc) (46.30%), partial pressure constant (61.11%), the relationship between Kc and Kp (38.89%), degree of dissociation (33.33%), equilibrium shift according to Le Chatelier's principle (65.74%), and chemical equilibrium in industry (38.89%). The findings demonstrate that misconceptions persist among students regarding understanding chemical equilibrium concepts.

Abstract

This research is an Active Knowledge Sharing Strategy in learning chemical bonds to examine its effect on cognitive achievement and learning activities of students. This strategy encourages students to be active subjects in the learning process, not just recipients of information. Quantitative approach with Intact Group Comparison design was used at SMAS Syamsuddhuha in the odd semester of the 2024/2025 academic year. The sample was taken purposively by considering certain characteristics: each class consisted of 20 students. The research instruments consisted of 16 multiple choice questions and observation sheets that had been tested for validity, reliability, difficulty level, and differentiation. The results showed that the experimental class using active knowledge sharing strategy had an average cognitive achievement of 72.50 far above the control class which reached 56.25. In terms of learning activities, the experimental class achieved an average score of 75.22 almost twice that of the control class of 40.47, indicating a statistically significant difference. Thus, the active knowledge sharing strategy proved to be effective in improving students' cognitive understanding and learning activities on chemical bonding materials.

Abstract

Basic laboratory skills are essential skills that Chemistry Education students must possess as future science educators. Accuracy in observation and precision in measurement are essential foundations for understanding chemical concepts through experimental activities. However, initial assessment results indicated that these skills were not yet optimally developed, especially among beginning students. Based on this condition, this community service activity was structured as intensive training focused on improving observation and measurement skills through workshops, demonstrations of laboratory equipment use, hands-on practice, and mentoring sessions. The program was attended by 26 students and lasted for three days. The evaluation of the activity showed improvements in the participants' procedural knowledge, technical skills, and scientific attitudes. This training proved effective in improving laboratory literacy and is recommended for ongoing implementation to strengthen students' competencies as future chemistry teachers.

Abstract

This study investigated the effect of the Process Oriented Guided Inquiry Learning (POGIL) model on Grade 10 students’ chemical literacy in Green Chemistry topics using a quantitative experimental approach with an intact group comparison design. Two pre-existing classes were assigned as an experimental group taught using POGIL and a control group taught using Direct Instruction, with posttest-only assessment. The sample consisted of 59 Grade 10 students selected through purposive sampling (30 experimental, 29 control). A PISA-style chemical literacy test measuring content, context, and competency dimensions was used as the research instrument. Data were analyzed using descriptive statistics, tests of normality and homogeneity, and an independent samples t-test at a significance level of 0.05. The results showed that students taught using POGIL achieved a higher mean chemical literacy score (81.1) than those taught using Direct Instruction (70.1), with the difference being statistically significant (p 0.05). These findings demonstrate that the POGIL model has a positive effect on students’ chemical literacy in Green Chemistry contexts and supports its application as a literacy- and sustainability-oriented instructional approach.

Abstract

This study is motivated by low levels of self-efficacy and learning achievement among students in General Chemistry, which are often associated with the material's abstract nature and the limited use of active learning approaches. This study aims to examine differences in students’ self-efficacy and learning outcomes between the Case-Based Learning (CBL) model and the Direct Instruction (DI) model. The study employed an intact-group comparison (quasi-experimental) design involving 44 students from the Chemistry Education Program at Malikussaleh University, divided into an experimental group (CBL) and a control group (DI). Research instruments included a self-efficacy questionnaire and a multiple-choice posttest. The results revealed statistically significant differences between the two groups in both self-efficacy (t = 13.715; p < .001) and learning outcomes (t = 8.793; p < .001). Students in the CBL group obtained higher mean scores in self-efficacy (72.86) and learning outcomes (83.27) compared to those in the DI group. These findings indicate that Case-Based Learning is associated with higher self-efficacy and better learning outcomes in General Chemistry. The study suggests that CBL can be considered an alternative instructional approach to support active and contextual learning in science education.
