Abstract

This research aims to determine the effect of the Inquiry Training model on students' Higher-Order Thinking Skills (HOTS) literacy, specifically in the context of Work, Energy, and Simple Machine topics at SMPN 27 Medan. The research is driven by two specific objectives: (1) to assess whether the application of the Inquiry Training model influences students' HOTS literacy compared to the expository model, and (2) to identify which category of HOTS literacy is most developed through the Inquiry Training model. This Research Uses Quasi-Experimental method with a two-group pretest-posttest design. The sampling technique uses random sampling. The research sample consisted of two classes, namely class VIII-3 use inquiry Training model and VIII-2 use expository model, each class consisted of 31 students. Data were collected using pretest and posttest assessments of 20 multiple-choice questions designed to measure HOTS literacy across cognitive domains (C4, C5, and C6). The N-gain for the experiment class was 75.45%, and 45.22% in the control class. In the t test calculation, the calculated tcount was 3.89, with ttable 2.001. The experiment class demonstrated the highest improvement in the cognitive domain of evaluation reasoning (C6), with N gain of 96%. The findings suggest that the Inquiry Training model effectively enhances students' HOTS literacy, particularly in science subjects,work, energy, and simple machines.

Abstract

This study aims to develop and implement an integrated learning model combining Project-Based Learning (PjBL) and Guided Inquiry Learning (GIL) to enhance science literacy in students within the advanced science education course. The study was conducted to students from the Elementary School Teacher Education Program at the Catholic University of Santo Thomas, focusing on the topic of States of Matter. A quasi-experimental design with a pre-test – post-test control group design was employed, where the control group received conventional teaching methods, and the experimental group engaged in the integrated PjBL-GIL model. The results reveal a significant difference in science literacy improvement between the groups. The experimental group, using the integrated PjBL-GIL model, showed a greater improvement (22.4%) compared to the control group (7.7%). Statistical analysis using a two-sample t-test confirmed the significance of this difference, with a t-value of 5.16 and a p-value of 0.000, indicating a statistically significant improvement in the experimental group. The effect size, measured by Cohen's d, was 2.53, indicating a large effect. ANCOVA results showed that even after controlling for baseline differences, the experimental group still demonstrated significantly higher post-test scores (p-value = 0.000). Furthermore, Pearson’s correlation analysis revealed a significant positive relationship between collaboration and science literacy improvement (r = 0.62, p = 0.01), emphasising the importance of collaboration in enhancing learning outcomes. These findings suggest that the integrated PjBL-GIL model is effective in improving critical thinking, problem-solving skills, and the application of scientific concepts. And it is recommended that this model be expanded in science education in Indonesia to further improve the quality of learning and students' science literacy.

Abstract

The aim of this research was to develop a Contextual Teaching and Learning (CTL) Model integrated with Batak ethnoculture and to test its effectiveness in improving the reading literacy of elementary school students. This study was necessary because of the students' low reading literacy levels and the lack of connection between teaching materials and the students' local and cultural context, which can hinder understanding. This development research used the Plomp model. The analysis phase included questionnaires and interviews to identify curriculum needs and relevant Batak ethnocultural richness. The CTL model based on Batak ethnoculture was designed as a learning package, including the syllabus, lesson plans (RPP), and teaching materials that featured folktales and Batak values. To test effectiveness, a quasi-experimental design was used. This involved an experimental group using the Batak ethnoculture-based CTL model and a control group using a conventional teaching model. Data was collected through reading literacy tests (comprehension, interpretation, and reflection) and student/teacher response questionnaires. The results showed that the developed Batak ethnoculture-based CTL Model met the criteria for validity, practicality, and effectiveness. The average scores on the reading literacy test for the experimental group were significantly (p<0.05) higher than those of the control group.

Abstract

Local wisdom plays a vital role in preserving cultural identity, fostering social harmony, and strengthening a community’s sense of belonging. Within the educational context, integrating local wisdom into learning activities creates meaningful connections between theoretical knowledge and the cultural realities experienced by students in their daily lives. This approach not only promotes contextual learning but also nurtures students’ appreciation of their heritage. This article explores the incorporation of Nias local wisdom into the Problem-Based Learning (PBL) model as a strategy to enhance both academic achievement and character formation. The Nias community possesses rich traditions, social values, and problem-solving practices rooted in cooperation, respect, and responsibility. By embedding these elements into the PBL framework, students are encouraged to engage in authentic learning experiences that mirror real-life challenges while reflecting their cultural identity. The findings show that the integration of Nias local wisdom within PBL significantly improves students’ cognitive, affective, and social competencies. Students demonstrate increased motivation, collaboration, and critical thinking, while also developing empathy and respect for cultural diversity. Moreover, this approach enriches the learning environment by linking education to the community’s cultural context. Consequently, the application of local wisdom in education not only produces academically competent learners but also individuals who are culturally grounded and socially responsible.

Abstract

This research aims to compare the effectiveness of sulfuric acid and hydrochloric acid catalysts in the esterification of frankincense cinnamic acid (STYRAX paraleoncomud PERK). Esterification of sulfuric acid catalyst is carried out with ethanol and for hydrochloric acid catalyst with methanol. Esterification was carried out by refluxing a mixture of 1:20 cinnamic acid - ethanol and methanol, with 3 mL of each catalyst at a temperature of 60oC for one hour. The results were rinsed with 3 x 50 mL distilled water and dried with anhydrous sodium sulfate. The results were filtered and verified for functional groups using FTIR and composition analysis using GC “ MS. The results of FTIR interpretation show a decrease in absorption intensity (-OH) at 3500 cm-1 as a functional group that reacts compared to the ester results as an indication of the ongoing esterification reaction. The resulting ethyl cinnamate has a high conversion of 84.42%. Methyl cinnamate also has a distinctive ester aroma but is clearer and based on GC-MS, the content of methyl cinnamate is relatively low, namely 34.40%, the remaining cinnamic acid is 37.28%, and various side products of 28.32%. Thus, the catalyst that provides better conversion is sulfuric acid, but it requires further purification by examining the appropriate absorbent and bleaching agent. The brown color of the ester product catalyzed by sulfuric acid is thought to occur due to the oxidation of the cinnamic acid double bond by the catalyst.
