Abstract

This study aimed to describe and compare the students’ fluency, flexibility, and originality in solving non-routine problems in the Palembang context. They were depicted from the student’s fluency, flexibility, and originality of solving the horizontal and vertical mathematization forms. This qualitative study employed. The subjects of this study were 30 students of grade nine of junior high schools in Palembang. The instruments used were tests and interviews. The tests were employed to investigate the written horizontal and vertical mathematizations forms. Meanwhile, the interviews were to explore the students’ ideas with inadequately detailed answers. Then, the test and interview data were reduced and grouped based on the indicators of creativity. The reduced data were presented in a descriptive form for conclusions. The results of the data analysis showed that the high-ability students were the most fluent and flexible in solving the problems. Still, the provided solutions were less original and tended to use formal mathematics in the forms of formulas, symbols, and operations. Meanwhile, the moderate-ability students tended to start to solve problems by simplifying them, then presenting them in visual images. The answer sheets of the moderate-ability students revealed their fluency in understanding the problems and solutions, flexibility, and originality of thinking. This study obtained different results from the low-ability students who tended to have difficulties understanding the problems and made many errors in solving them. Such a condition showed their inability to write the known data and relate the data to other facts they had already learned. As a result, their answers did not represent fluency, flexibility, and originality.

Abstract

This study aims to develop an RME-based worksheet for integer learning that meets the standards of validity and practicality. It has a potential effect on students' mathematical communication skills. This development research adopts the ADDIE stages, including analysis, design, development, implementation, and evaluation. The research participants involved 33 grade VII students at SMPN 33 Palembang. Data was collected through validation sheets, practicality sheets were assessed using a Likert scale of 1–5, and mathematical communication ability tests were evaluated based on scoring guidelines. Based on the results of the analysis, the worksheets developed reached a level of validity with an average score of 4.36 (very valid category). Initial practicality tests through one-to-one and small groups showed that the category was very practical, so the product was declared feasible for implementation. The results of the practicality test at the implementation stage also showed an average score of 4.60 (very practical category). The potential effect can be seen from the achievement of an average mathematical communication ability test score of 80.30 after the implementation of the worksheet (very good category). Thus, it can be concluded that the worksheet meets the aspects of validity and practicality and provides the expected potential effect.

Abstract

This research investigates the efficacy of combining Augmented Reality (AR) technology with the Realistic Mathematics Education (RME) methodology in developing students' mathematical problem-solving capabilities. The investigation examines how the AR-RME integration functions as a potential educational innovation for boosting learner involvement and conceptual comprehension. This research employs a combined design incorporating numerical and descriptive-analytical frameworks. A cohort of 17 secondary school adolescents engaged in AR-RME-facilitated learning across five instructional sessions. Evaluation of participants' problem-solving proficiency was conducted through comparative pre-intervention and post-intervention assessments based on Polya's four-stage methodology: issue identification, procedural planning, implementation of strategies, and outcomes evaluation. Systematic observations were conducted to evaluate student engagement levels. The results of the observations showed the enthusiasm and active participation of the students during the learning. Statistical analysis using paired t-tests revealed a significant improvement in problem-solving skills (t = 8.742, p < 0.05), with the average score increasing to 74.81%. These findings show that AR-RME effectively improves spatial reasoning and understanding of three-dimensional geometry concepts, especially on cubes and blocks. This study confirms that AR-RME is an innovative approach that enhances problem-solving skills and becomes a more interactive and effective learning alternative to conventional methods.

Abstract

The disconnect between mathematics content and real-world applications creates significant challenges for students' understanding of fraction operations, resulting in procedural learning without conceptual depth. This study develops and evaluates a STEM-based e-module integrating authentic contexts with systematic instructional design to enhance junior high school students' mathematical reasoning abilities. The research employed the ADDIE development model to create a STEM-based e-module on fraction operations using snack nutritional values as context. The Engineering Design Process (EDP) served as the central pedagogical framework, structuring activities through seven systematic stages: Define, Research, Plan, Create, Communicate, Redesign, and Evaluate, transforming abstract mathematical concepts into meaningful problem-solving experiences. Three experts validated the e-module across five dimensions: content feasibility, presentation quality, language appropriateness, practicality, and STEM integration. Practicality testing involved progressive trials: one-to-one (3 students), small group (6 students), and field implementation (30 students). Mathematical reasoning effectiveness was measured using contextual problem-solving assessments evaluating five indicators: conjecturing, pattern identification, mathematical manipulation, justification provision, and conclusion drawing. Validation results demonstrated exceptional quality, with the e-module achieving a 95.2% overall validity index. Practicality testing revealed an average satisfaction of 90.28%, categorized as "very practical." Students demonstrated substantial improvement in mathematical reasoning, with an average final assessment score of 77.68. Students performed strongest in drawing conclusions (87%) and providing justification (81.67%), while conjecturing achieved a rate of 64%. Qualitative analysis revealed that while high-ability students employed formal reasoning and symbolic representation, some medium-ability students relied more on narrative responses, reflecting a gap between intuitive understanding and formal expression. The study concludes that the developed e-module is valid, practical, and effective in fostering students' mathematical reasoning. Integrating EDP into STEM-based e-modules provides a promising pathway to bridge procedural knowledge and conceptual depth, promoting meaningful and transferable learning experiences.    Keywords: contextual learning, engineering design, fractions context, mathematical reasoning, STEM e-module.
