Abstract

This study addresses Indonesian students’ low scientific literacy (PISA 2022) by developing and validating a Tari Boranan Lamongan–contextualized physics assessment instrument on rigid body equilibrium. Existing PISA-aligned tests are rarely embedded in local culture. At the same time, local wisdom materials often do not measure all eight PISA scientific literacy indicators, creating a gap for culturally resonant yet comprehensive diagnostic tools. This study aimed to (1) develop and validate an eight-indicator, PISA-aligned scientific literacy instrument, (2) map Grade XI students’ literacy profiles across the eight indicators, and (3) explore how the Boranan context shapes students’ engagement and reasoning. Using a mixed-method embedded design, 73 Grade XI students in Lamongan Regency completed eight essay-based literacy tasks, and ten students participated in semi-structured interviews. Expert validation indicated high content relevance, cultural authenticity, and indicator alignment, and reliability analysis yielded Cronbach’s alpha = 0.82. Results showed most students were in the very low and low categories, with relative strengths in interpreting data (45%) and explaining phenomena (38%), but pronounced weaknesses in designing investigations (28%), evaluating credibility of information (25%), and making evidence-based decisions (30%). Interviews confirmed that cultural context enhanced engagement and visualization but did not automatically support mathematical formalization. These findings suggest that the instrument can be used diagnostically to help teachers design targeted scaffolding for higher-order literacy skills, particularly in investigation design, credibility evaluation, and evidence-based decision-making, within culturally responsive physics learning.

Abstract

21st-century education requires students to master mathematical problem-solving skills and self-regulated learning (SRL), but these skills remain a challenge for junior high school students in Indonesia. This study aims to examine the impact of implementing a Collaborative Learning Model of the PBL combined with a scientific approach (observing, questioning, reasoning/trying, communicating) on students' mathematical problem-solving skills and SRL. The study used a pre-experimental method with a One-Group Pretest–Posttest design on 31 seventh-grade students at a junior high school in Sleman Regency. Data on problem-solving skills were collected through a 5-item essay test with a maximum theoretical score of 50, while SRL was measured using a Likert scale questionnaire. Inferential analysis used the Wilcoxon signed-rank test for problem-solving skills (the assumption of normality was not met) and the paired sample t-test for SRL. The results showed a significant increase in problem-solving skills from 15.32 to 30.92, with posttest achievement equivalent to 61.84% of the theoretical maximum score. SRL also increased significantly from 121.81 to 122.74, although the mean difference was relatively small compared to the scale range. These findings indicate changes in students’ achievement after the intervention; however, the results should be interpreted cautiously due to the short intervention duration and the limitations of the one-group pretest–posttest design without a control group.

Abstract

This study investigates the types and underlying causes of students’ errors when evaluating non-routine algebraic problems that present procedurally plausible but logically invalid solution steps. The participants were 37 ninth-grade junior high school students from East Java, Indonesia, who had previously studied basic algebraic operations. Data were collected through a diagnostic task involving an algebraic fallacy that leads to a contradictory conclusion (e.g., 2 = 3), followed by semi-structured interviews with selected students. The analysis was guided by Newman’s Error Analysis (NEA), focusing on reading, comprehension, transformation, process skills, and encoding errors. Students’ written responses were independently coded by the researchers using predefined NEA indicators, and discrepancies were resolved through discussion. Descriptive statistics were used to summarize error frequencies, while interview data were analyzed qualitatively to explore students’ reasoning. The results indicate that transformation errors were the most dominant, occurring in 48.64% of students’ responses, particularly due to inappropriate cancellation of algebraic factors without considering domain restrictions. Many students accepted contradictory conclusions such as 2 = 3 or 3 = 2 as valid, as long as the solution steps appeared procedurally correct. These findings suggest that students tend to rely on mechanical algebraic procedures rather than validating the conceptual legitimacy of each transformation. The study highlights the importance of emphasizing equivalence-preserving transformations and domain conditions in algebra instruction, especially through non-routine tasks that require justification and critical validation of solution steps.

Abstract

This study investigates the improvement of students’ critical thinking skills following the implementation of a web-based learning platform integrated with a guided inquiry model on dynamic fluid topics. The study employed a pre-experimental one-group pretest–posttest design involving 30 Grade XI students at a public senior high school in Banjarmasin, Indonesia. Students’ critical thinking skills were measured using an essay-based test developed based on Ennis’ critical thinking framework, covering interpretation, analysis, inference, evaluation, and explanation. The maximum possible score was 100, with student responses scored using an analytical rubric and converted to a percentage scale. Data were analyzed using normalized gain (N-Gain) and a paired-sample t-test. The results showed an increase in the mean score from 3.82 on the pretest to 79.69 on the posttest, with an N-Gain of 0.74 (high category). The paired-sample t-test indicated a statistically significant difference between pretest and posttest scores (p < 0.05), suggesting a substantial improvement in students’ critical thinking skills after the intervention. Improvements were observed across all critical thinking indicators, particularly in analysis and evaluation. Although the findings indicate positive learning gains, the use of a one-group pretest–posttest design limits causal interpretation. Nevertheless, the results suggest that web-based guided inquiry learning has the potential to support the development of students’ critical thinking skills in physics learning, especially for abstract topics such as dynamic fluids.

Abstract

Alternative energy learning in schools requires instructional materials that can connect scientific concepts with real-world problem solving. However, current learning practices are still often dominated by theoretical explanations, textbook-based instruction, and limited project-oriented activities. This study aimed to analyze physics teachers’ needs for developing STEM-PjBL-based student worksheets to support students’ Creative Problem Solving (CPS) in alternative energy learning. This study employed a descriptive survey method involving 27 physics teachers in Lampung Province. Data were collected using a teacher needs questionnaire and analyzed using descriptive statistics. The results showed that the teacher needs questionnaire was categorized as very valid, with an average validity percentage of 80.54%. In alternative energy learning, Problem Based Learning was the most frequently used learning model, while Project Based Learning was used by only 33.3% of teachers. Student worksheets and learning videos were the most commonly used learning resources, each used by 85.2% of teachers, while printed books were still used by 63.0% of teachers. Although 85.2% of teachers had used student worksheets and 59.3% had developed their own worksheets, only 48.1% reported using worksheets integrated with STEM-PjBL. Furthermore, 96.3% of teachers stated that they needed student worksheets designed to support students’ Creative Problem Solving. These findings indicate a gap between the availability of student worksheets and their integration with structured STEM-PjBL and CPS-oriented learning activities. Therefore, the development of STEM-PjBL-based student worksheets is needed to support more contextual, project-based, and problem-solving-oriented alternative energy learning.

Abstract

Mathematical communication skills are essential for enabling students to express mathematical ideas, use representations, and explain reasoning clearly. However, elementary students often experience difficulties in using mathematical symbols, interpreting visual representations, and presenting problem-solving steps systematically. This study examined students’ mathematical communication skills after the implementation of ethnomathematics-based learning using Mbojo cultural contexts. A quasi-experimental method with a one-group posttest-only design was employed. The participants were 15 fourth-grade students selected through total sampling. Data were collected using a mathematical communication skills test and analyzed using a one-sample t-test with a benchmark score of 70, based on the Minimum Mastery Criteria. The results showed that students’ mean score was 73.87, which was significantly higher than the benchmark, t(14) = 2.822, p = .015. These findings indicate that ethnomathematics-based learning using Mbojo cultural contexts can support students’ mathematical communication skills. However, due to the absence of a pretest and control group, the findings should be interpreted as evidence of students’ achievement above the benchmark rather than strong causal evidence.

Abstract

Tropical cyclones in the Southern Indian Ocean pose severe threats to coastal infrastructure and socio-economic stability, yet predicting their recurving trajectories and intensity remains a significant meteorological challenge. This study evaluates the performance of a particle-motion-based machine learning framework, utilizing the Trackpy library, to forecast cyclone behavior. Leveraging historical data from 2018 to 2025 (JTWC and IBTrACS), the model treats cyclones as physical particles with temporal inertia, employing a multi-lag feature to capture movement momentum. Evaluation using a dataset of 115 cyclones (78:22 train/test ratio) reveals that the Trackpy framework achieves high spatial precision, with Mean Squared Error (MSE) values of 0.1728 for latitude (±33.3 km) and 1.0250 for longitude (±53.2 km). While the intensity prediction yielded a higher MSE of 47.7544 (approximately 6.9-knot deviation), the model successfully captured major strengthening and weakening phases across prominent cyclones, including TC Wallace and TC Neville. These findings demonstrate that integrating temporal inertia is highly effective for maintaining trajectory consistency, establishing Trackpy as a robust architectural foundation for operational forecasting. Further optimization via hybrid models and additional meteorological variables is recommended to enhance intensity accuracy.

Abstract

The ability to create contextual problems is essential for pre-service teachers. However, many teachers simply adapt or adopt existing problems when creating contextual problems. This study aims to explore the critical thinking skills in analysing contextual problems and the mathematical beliefs that underlie the analysis process. This qualitative study involved 40 pre-service primary school teacher participants, with four participants selected for in-depth interviews. The research instruments included vignettes, interview guidelines, and observation sheets. The data were validated using triangulation methods. The study indicates that pre-service primary school teachers can be categorised into non-critical thinkers (35 participants), emergent critical thinkers (3 participants), and advanced critical thinkers (2 participants). Non-critical thinkers demonstrate an ability to understand problems that they have previously studied, as their understanding constrained to the formulae and procedures demonstrated by their teachers. Emergent critical thinkers showed the ability to question the problem formulation and evaluate its contextual relevance, although their reasoning remained influenced by teacher authority. Advanced critical thinkers are characterised by a high level of critical thinking aptitude, often attributed to their perception of mathematics as a discipline rooted in logical reasoning.

Abstract

The use of Augmented Reality (AR) in learning has shown rapid development. This study aims to analyze the effect of AR integration on students’ creative thinking abilities in the topic of surface area and volume of cubes and rectangular prisms. We applied a quasi-experimental design by utilizing two existing classes, namely an experimental class consisting of 32 students and a control class consisting of 30 students. We used an essay test instrument measuring creative thinking ability that had undergone expert validation using the Q-Cochran test before being used for data collection. Data analysis was conducted using descriptive statistics and an independent samples t-test. The analysis showed a significant difference between the post-test scores of the two groups, with t(60) = 2.31 and p = 0.012 (one-tailed). The effect size calculation produced a Cohen’s d value of 0.60 (moderate effect). These results indicate that students who participated in AR-assisted mathematics learning obtained higher creative thinking scores than students who participated in learning without AR support. This finding indicates that the implementation of AR is able to provide a meaningful effect as well as a positive contribution to the development of students’ creative thinking abilities in solving mathematics problems.

Abstract

Mathematics learning outcomes in elementary schools remain suboptimal, partly due to the lack of contextualized learning. There are not many alternative learning media options available for teachers to facilitate contextual mathematics learning. Therefore, this study aims to design and develop an e-novel for elementary school geometry. This research is a research and development, with the 4D development model. This research was conducted at SDN 038 Kanusuang, SDN 034 Rappang, and SDN 019 Sila-Sila, Poliwali Mandar Regency, West Sulawesi, Indonesia. The research subjects included two validators (media experts and material experts), three class teachers, and all fifth-grade students from three schools. After going through the 4D stage, an e-novel development product was produced. The characteristics of e-novel product possesses are a story-based digital media, containing narratives, dialogues, illustrations, and learning activities that connect mathematical concepts with the local Mandar cultural context. Based on the results of the validity test conducted by media experts and material experts, as well as the practicality test conducted by teachers and students, the product was deemed highly valid (average score 90%) and categorized as very practical (average score 95,47%). Thus, the developed ethnomathematics-based e-novel are valid dan practical for use as a learning medium for geometry in fifth-grade elementary schools. Although there are still weaknesses, it has not yet reached the stage of testing its effectiveness on the process and results of student learning achievement.
