Abstract

This study aims to analyze the feasibility of a scientific reasoning ability test instrument for prospective science teachers using the Rasch model. The instrument developed refers to Lawson's Classroom Test of Scientific Reasoning (LCTSR) indicators, focusing on scientific reasoning abilities, including variable control, combinatorial, probability, relational, and proportional thinking. The analysis was carried out using the Rasch Model with the WINSTEPS Version 5.7.3.0 application to test the validity, reliability, and characteristics of the test items. The feasibility test was carried out on 40 multiple-choice questions, tested on 110 test samples. The analysis results showed that 25 of the 40 questions were valid and covered all indicators of problem-solving skills. The test instrument also has a high level of internal consistency with a person reliability value of 0.84 and an item reliability of 0.95. Analysis of the level of difficulty of the test items showed a balanced distribution between very difficult, difficult, moderate, and easy questions. No items were detected as biased, indicating that this instrument is fair and can be used without favoring one group of individuals. Overall, the developed problem-solving skills test instrument is valid and reliable for use on prospective science teachers, assisting educators in evaluating students' problem-solving skills, providing constructive feedback, and improving the quality of learning in science.

Abstract

This study aims to develop an interactive e-module integrated with the Project-Based Learning (PjBL) model to enhance junior high school students’ independence and understanding of alternative energy concepts. Using the ADDIE-based Research and Development (R&D) method, the process included analysis, design, development, implementation, and evaluation stages. Expert validation, along with readability and practicality tests involving students, was conducted using various instruments, including questionnaires and pretest-posttest evaluations. The e-module achieved high validity, with Aiken's V scores of 0.94 for both media and content. It also gained high readability (84.3%) and practicality (89%) scores. The Wilcoxon test (p < 0.001) and a normalized gain of 0.75 indicated a significant improvement in students’ conceptual understanding. Additionally, the rate of learning independence increased by 85%. The Mann-Whitney test confirmed significant differences between experimental and control groups, proving the module's effectiveness in digital and contextual science learning. Overall, the e-module is effective for project-based science education. The study recommends applying similar approaches in other subjects and integrating advanced technology to support personalized and effective learning in the 21st century.

Abstract

Problem: the integration of local wisdom in junior secondary science learning remains limited, contributing to low students’ creative thinking skills. Furthermore, the use of digital teaching materials that support project-based learning is not yet optimal, resulting in less contextual and engaging learning. Objective: this study aimed to develop and examine the feasibility and effectiveness of a Project-Based Learning (PjBL)-based e-booklet on temperature and heat integrated with the local wisdom of Magelang pottery. Method: this research employed a Research and Development (R&D) approach using the ADDIE model and involved an experimental and a control class. The evaluation focused on feasibility (validity, readability, and practicality) and efeftiviness (product and process performance, as well as learning outcomes). Results: the developed e-booklet was found to be valid, practical, and received positive responses from students. Conclusion: the e-booklet was sufficiently effective in enhanving student engagement and creative thinking skills, making it a feasible contextual teaching material for junior secondary science learning.

Abstract

This study aims to analyze the vegetation structure and ecosystem components of Mount Ciremai National Park (MCNP) using the parameters of density, frequency, dominance, and the Important Value Index (IVI). Data were collected across 3 observation stations using the quadrat sampling method with three-tiered plot sizes (1×1 m, 5×5 m, and 10×10 m). A total of 53 vegetation species comprising 847 individuals were identified, predominantly dominated by understory plants such as Oplismenus hirtellus and Homalomena philipinensis. The IVI analysis revealed distinct key species across different strata: H. philipinensis in the seedling stratum, Dysoxylum spectabile and D. cauliflorum in the sapling stratum, and Gurea bullata in the tree stratum, which exhibited high dominance despite a low individual count. Furthermore, environmental factors, including acidic soil pH (5.6–6.7) and stable temperatures (21–22°C), significantly influenced these distribution patterns. Notably, the stand structure was highly unbalanced, with a massive dominance of seedlings compared to saplings and trees, indicating a severe regeneration bottleneck. These findings imply that while the understory ecosystem remains stable, the forest faces a critical threat to its natural tree succession. Consequently, long term monitoring and targeted conservation strategies such as active seedling protection are urgently needed to ensure the sustainability of the forest structure in MCNP.

Abstract

Instruments composed of items worded in the same direction may be vulnerable to response bias. This study evaluated a modified Computational Thinking Scale (CTS) comprising 19 matched pairs of positively and negatively worded items. An instrument-development design adapted from ADDIE was used. The study population comprised science-track senior high school students in the Surakarta Residency. The sample included 393 Grade XI students from three purposively selected schools. Data were collected using a 38-item, five-category self-report questionnaire. Five experts assessed content validity, yielding coefficients of 0.80–0.95 and a mean of 0.89. Responses were analyzed using the Rasch model in Winsteps 5.7.3.0. Cronbach’s alpha and person reliability were 0.66, with person separation of 1.40, whereas item reliability was 1.00 and item separation was 14.67. Response categories showed ordered observed averages and Andrich thresholds, with outfit MNSQ values of 0.91–1.07. All items met the primary outfit MNSQ criterion, ranging from 0.82 to 1.21. Three algorithmic-thinking items showed statistically significant but small gender DIF contrasts of 0.30–0.35 logits. The hypothesis was partially supported because the instrument showed acceptable item-level functioning but limited person-level discrimination. Future studies should examine wording effects, matched-pair equivalence, dimensionality, and local dependence in broader, more diverse samples.
