Abstract

This study examines the effectiveness of the Snowball Throwing cooperative learning strategy in improving science learning outcomes among fourth-grade students at MI Ma’arif Pabelan, Central Java, Indonesia. A classroom action research design was applied over three cycles, each consisting of planning, implementation, observation, and reflection. The participants included 33 students (22 males and 11 females). Data were gathered through achievement tests, structured observations, and documentation, and were analyzed using descriptive statistics. The results revealed steady improvements in student mastery: 51.51% in Cycle I, 69.69% in Cycle II, and 87.87% in Cycle III, surpassing both the minimum competency standard (65) and the classical completeness benchmark (85%). These findings confirm that Snowball Throwing is effective in enhancing engagement and learning achievement, especially in teaching conceptually abstract science topics such as the Earth’s appearance and celestial motion. The study contributes to the literature by documenting iterative improvements across multiple cycles, highlighting its applicability in underrepresented contexts such as Islamic elementary schools. Beyond affirming the value of cooperative learning, this research emphasizes the importance of reflective teaching practices and iterative instructional refinement in achieving sustainable improvements in science education.

Abstract

This study addresses the need for classroom‐level evidence on student activeness in junior-high science by estimating the proportion of learners across engagement categories during routine lessons. Using a quantitative, descriptive, cross-sectional design, data were collected in a single administration from an intact eighth-grade class at SMPN 14 Bengkulu City (N = 30; 15 male, 15 female; response rate 100%). A 15-item Likert-type questionnaire operationalized five indicators of classroom activeness (participation in discussions, articulating opinions, initiating questions, problem solving, and involvement in practical work). Responses were summarized as frequencies and percentages across five categories (Inactive, Less active, Moderately active, Active, Very active). Results showed no students in the Inactive or Less active categories (0% each), with 10% Moderately active, 30% Active, and 60% Very active, indicating a strongly favorable engagement profile in day-to-day science instruction. These findings suggest that classroom routines in the observed setting support frequent student voice, questioning, and hands-on involvement, and they provide a category-based benchmark that makes heterogeneity visible for instructional decision-making. The principal contribution is a practical baseline reported as proportions rather than only mean scores that schools can use to set targets, tailor supports for moderately active students, and monitor shifts over time. Implications include guiding teacher professional development toward participation-eliciting routines, informing resource allocation for practical activities, and establishing a measurement approach that can be scaled and triangulated (e.g., with classroom observations) to drive continuous improvement in lower-secondary science learning.

Abstract

This study explores the ecotourism potential of the Bhadrika Mangrove Tourism Park in Bengkulu, Indonesia, with the aim of assessing its attractiveness as a sustainable tourism destination that can contribute to both environmental conservation and local economic development. The research was conducted in July-August 2020, utilizing a mixed-methods approach that combined field observations and semi-structured interviews with local stakeholders, community members, and visitors. The data were analyzed using descriptive methods and the Scenic Beauty Estimation (SBE) technique to evaluate the aesthetic appeal of the park’s mangrove ecosystems. The results revealed that the park’s diverse mangrove species, river estuaries, and coastal landscapes offer significant potential for educational and recreational tourism activities. Key attractions include guided tours, photography zones, children’s play areas, and local food vendors. The study also highlighted strong community support for ecotourism, with local residents expressing interest in participating in tourism-related activities and benefiting from increased job opportunities. Despite the promising potential, the study identified several challenges, including the need for infrastructure improvements and the importance of maintaining a balance between tourism growth and ecological preservation. This research contributes to the growing body of knowledge on mangrove ecotourism by providing a detailed case study of a lesser-known mangrove site in Indonesia. The findings suggest that with appropriate management, the Bhadrika Mangrove Tourism Park could serve as a model for sustainable ecotourism in coastal regions, promoting both conservation and community empowerment.

Abstract

Dengue Hemorrhagic Fever (DHF) remains a major public health problem in tropical and subtropical countries, including Indonesia, where periodic outbreaks are strongly associated with environmental conditions and community behaviors. This study aimed to analyze the relationship between mosquito nest eradication through the implementation of 3M Plus draining, closing, recycling, and additional preventive practices and the incidence of DHF in the working area of the Beringin Raya Public Health Center, Bengkulu City. A case-control survey design was employed involving 72 respondents, consisting of 36 cases and 36 controls selected through total sampling. Data were collected using structured questionnaires and analyzed with the Chi-Square test to assess associations, while odds ratios with 95% confidence intervals were calculated to determine risk estimates. The findings revealed that 43.1% of respondents demonstrated poor implementation of 3M Plus and 56.9% showed good practices. Bivariate analysis indicated a significant relationship between mosquito nest eradication behaviors and DHF incidence (χ² = 6.977; p = 0.017), with individuals demonstrating poor preventive practices being 3.64 times more likely to contract DHF compared to those with good practices. These results emphasize the critical role of consistent environmental management and community participation in minimizing vector breeding and reducing disease transmission. The novelty of this study lies in providing localized empirical evidence from Bengkulu City, where research on dengue prevention remains limited, thereby contributing to the evidence base for community-based vector control programs. The implications suggest that health centers and policymakers should strengthen health promotion, monitoring, and community engagement strategies to improve adherence to 3M Plus as an effective measure for reducing dengue incidence in endemic areas.

Abstract

Assessment quality is a crucial element in ensuring that science education achieves its intended learning objectives, particularly at the junior secondary level where foundational concepts are introduced. This study aimed to evaluate the quality of teacher-constructed mid-term examination items in Grade VII science by focusing on item difficulty, discrimination index, and overall reliability. Using a quantitative descriptive design, data were collected from 68 student responses to 25 test items, comprising 20 multiple-choice and 5 essay questions, and analyzed through classical test theory. The findings showed that 28% of items were classified as easy, 52% as moderate, and 20% as difficult, with 60% demonstrating acceptable or good discrimination power and a KR-20 reliability coefficient of 0.72, indicating adequate internal consistency. While the results suggest that the test achieved a balanced level of difficulty and acceptable reliability, the presence of items with poor discrimination and extreme difficulty levels reveals weaknesses in test construction. The discussion underscores that systematic item analysis is essential to refine teacher-made assessments and align them with both curriculum standards and international benchmarks. The novelty of this study lies in its focus on teacher-constructed science tests in junior secondary schools in Indonesia, a context that remains underexplored in the literature. The implications of this research point to the need for enhanced teacher assessment literacy, institutional support, and continuous evaluation practices to improve the validity and reliability of classroom-based examinations.
