Abstract

This study explores the relationship between mathematical creative thinking, students’ cognitive styles (Field Independent and Field Dependent), and the Problem Based Learning (PBL) model in solving open-ended problems. Using a Systematic Literature Review (SLR) based on the PRISMA framework, this research analyzed 15 relevant articles published between 2018 and 2025. The findings reveal that cognitive styles influence students' creative thinking patterns. Field Independent students tend to produce more original and flexible solutions, while Field Dependent students perform better with structured guidance. Moreover, PBL is effective in enhancing the dimensions of creative thinking—fluency, flexibility, originality, and elaboration—especially when combined with open-ended tasks. This review highlights the importance of adaptive instructional design that integrates PBL and accounts for students’ cognitive styles to foster mathematical creative thinking skills.

Abstract

This study aims to comprehensively analyze the needs (Define stage) in developing a Natural Science (IPA) teaching module aimed at increasing environmental awareness of Grade VIII junior high school students. This study adopted the Research and Development (R&D) method, focusing on the Needs Analysis stage of the 4-D model (Define). Data collection was conducted through teacher interviews and distribution of needs analysis questionnaires to students and teachers. The research subjects consisted of Grade VIII students and three science teachers in a public junior high school. The results confirmed a significant gap between ideal learning conditions and current practices. The main findings indicated a very high need (90.20%) for a module that integrates in-depth learning, as current teaching methods are largely conventional, evidenced by the lowest score in the method aspect (38.24%). Furthermore, despite high initial awareness (84.31% and 63.97%), the learning materials lacked a specific module on Climate Change and failed to fully transform knowledge into active ecological behavior. This study strongly concludes that contextual, interactive, and technology-integrated science teaching modules are urgently needed to facilitate reflective thinking, encourage active ecological behavior, and bridge the gap between conceptual mastery and practical environmental responsibility in Grade VIII students.

Abstract

This research aimed to evaluate the effectiveness of the Teaching at the Right Level (TaRL) approach on student learning outcomes regarding relations and functions. This experimental study employed a pretest-posttest control group design at State Junior High School 5 Manado. The experimental class was taught using the TaRL approach, while the control class received Direct Instruction. Results indicated that the average learning outcomes of the experimental class (81.80) significantly outperformed the control class (71.48). Hypothesis testing via t-test yielded tcount = 3.619 > ttabel = 2.011 at a significance level of 0.05, confirming significant difference. Furthermore, TaRL met all effectiveness criteria: 1) the average score exceeded the learning objective attainment threshold (KKTP) of 75;2) classical mastery was achieved; 3) student responses to the learning process were positive. In conclusion, the TaRL approach is effective in improving student learning outcomes for relations and functions material among eighth-grade students.

Abstract

Preparing preservice science teachers for future teaching requires learning approaches that strengthen pedagogical competence while integrating scientific knowledge with authentic classroom practices. Project-based learning offers such an approach by promoting active engagement and meaningful professional experiences. This study aimed to examine the contribution of project-based learning to the development of science subject-specific pedagogy among preservice science teachers. This study employed a pre-experimental one-shot post-test design. Participants completed a project-based learning program over eight instructional meetings and subsequently responded to a 10-item questionnaire measuring learning quality, motivation, and performance. The data were analyzed using descriptive statistics, supported by responses to open-ended questions. The results showed that learning quality (M = 4.38) and motivation (M = 4.28) were categorized as very good, while performance (M = 4.18) was categorized as good. These findings indicate that project-based learning contributes positively to preservice science teachers' ability to develop science subject-specific pedagogy by strengthening conceptual understanding, enhancing pedagogical competence, and fostering creativity and innovation in instructional design.

Abstract

Poverty remains a significant development challenge requiring effective intervention strategies supported by accurate predictive models. This study constructs exponential and logistic mathematical models to estimate the poor population in Banggai Kepulauan Regency, using historical data from 2013 to 2024. The models were constructed through linearization techniques, and parameters were estimated using the least squares method. Both models demonstrated excellent accuracy levels with Mean Absolute Percentage Error (MAPE) values below 10%, where the exponential model achieved MAPE of 2.17% and the logistic model 4.41%. Sensitivity analysis through growth rate parameter variations confirmed model robustness. Projections for 2025–2030 indicate a declining trend in poverty, with the exponential model N(t) = 19,400 × e-0.022574t predicting approximately 13,217 poor people by 2030. These findings provide scientific evidence that the exponential model can serve as a reliable analytical tool for poverty alleviation policy planning in Banggai Kepulauan Regency, enabling more targeted and evidence-based interventions
