Abstract

Differences in students’ learning styles often affect learning outcomes, particularly in abstract and conceptual subjects such as chemical bonding. This study aims to examine the influence of learning styles on the learning outcomes of Grade X students in the topic of chemical bonding. A comparative quantitative approach was employed using an ex post facto design. The sample consisted of 75 students selected through a saturated sampling technique. Data were collected through a learning style identification questionnaire and documentation of daily test scores. Data analysis was conducted using a One-Way ANOVA test followed by the Tukey HSD test. The results showed that learning styles had a significant effect on learning outcomes (p = 0.027), with students with an auditory learning style achieving the highest average scores. Significant differences were found between auditory and kinesthetic groups, as well as between visual and auditory groups. These findings emphasize the importance of aligning instructional strategies with students’ learning styles to enhance learning effectiveness. Observations also revealed that kinesthetic learners showed lower engagement, indicating the need for more active and exploratory learning approaches. This study recommends that teachers map students’ learning styles as a basis for designing responsive and adaptive instruction, especially for complex chemistry topics.

Abstract

The background of this study is the low level of student participation, critical thinking skills, and collaboration abilities, as well as suboptimal learning outcomes in IPAS, particularly in IPS material. This condition is caused by the dominance of one-way teaching methods, limited innovative learning models and media, and minimal opportunities for students to discuss, collaborate, and actively participate. To address these problems, the Problem Based Learning (PBL) model was implemented, combined with the GNM model (Group Investigation, Numbered Heads Together, and Mind Mapping) and the traditional game Cublak-Cublak Suweng. This study is a Classroom Action Research (CAR) conducted over three meetings with 20 fourth-grade students at SDN Simpang Empat, Banjar Regency, in the even semester of the 2023/2024 academic year. Data were collected in both qualitative and quantitative forms through observations of teacher activities, student activities, critical thinking skills, collaboration skills, and learning outcomes. The success criteria were set if at least 80% of students were categorized as “Very Active” and 80% achieved scores ?72. The results showed improvements from the first to the third meeting, where teacher and student activities reached the “Very Good” and “Very Active” categories, critical thinking and collaboration skills improved to “Very Skilled,” and the learning completeness reached 85%. Therefore, the implementation of PBL combined with GNM and traditional games has proven effective in enhancing the quality of IPAS learning

Abstract

Graph is a discrete mathematical representation widely used to model connectivity in various fields. This study discusses the application of Hamiltonian concepts on the complete bipartite graph K_8^2 as a model for vaccine service route planning at the local level (district). The graph K_8^2 represents eight health facilities in a region, where each facility consists of seven service locations and one other supporting facility. The research method includes constructing a complete bipartite graph, identifying vertices and circuits, and tracing Hamiltonian paths to visualize routes that connect each vertex once in a closed journey. The results show that the K_8^2 graph is effective for designing vaccine distribution routes that systematically and efficiently connect all facilities across eight districts. The complete bipartite graph with Hamiltonian properties proves applicable as a model for public service route planning, with potential implementation in optimizing health logistics distribution, facility inspection, and emergency response for vaccination services at the local level.

Abstract

The problem addressed in this study stems from the low level of scientific literacy among elementary school students and the suboptimal implementation of Education for Sustainable Development (ESD), which has not been well integrated with local wisdom. In addition, Sundanese gastronomic knowledge is increasingly being eroded by modernization, highlighting the need for innovative, contextual, and meaningful learning media. This study aims to analyze the need for developing a learning medium in the form of a storybook based on Ethno-ESD Sundanese gastronomy as a foundation for strengthening students’ scientific literacy. This study employed a quantitative descriptive method within the Design Based Research (DBR) framework at the needs analysis stage. The sample consisted of fifth-grade elementary school students selected through purposive sampling. Data were collected using a Likert-scale questionnaire covering five aspects: prior learning understanding, learning media needs, scientific literacy, integration of Ethno-ESD, and students’ interest in storybooks. Data were analyzed using descriptive statistics in the form of mean scores. The results indicate that students’ need for developing an Ethno-ESD-based storybook is high, with an average score of 4.13. All aspects fall into high to very high categories, with the highest score in the integration of Ethno-ESD Sundanese gastronomy. These findings suggest that students require contextual and engaging learning media that integrate scientific literacy with daily life and local cultural values. Therefore, the development of an Ethno-ESD-based Sundanese gastronomy storybook has strong potential as an innovative solution to enhance elementary students’ scientific literacy.
