Development of STEAM-based Teaching Materials in Problem Based Learning Model to Improve Mathematical Reasoning
type: item
description: Mathematical reasoning is an important ability in using concepts and logic based on existing rules to solve various problems by making logical and accountable conclusions. However, based on a preliminary study by giving test questions to students, it was found that students' mathematical reasoning is still relatively low. This study was a development research that aims to develop and determine the quality of teaching materials based on Science, Technology, Engineering, Arts, and Mathematics (STEAM) in a problem-based learning model seen from the suitability of feasible characteristics consisting of valid, practical, and effective. This research was conducted using the Research and Development (R&D) stage with a modified 4-D model and implemented at SMP Negeri 2 Geyer in 2023. The data collection techniques used were tests and questionnaires. The results of the study indicate that the teaching materials have met the eligibility criteria. The validity results show a percentage of 90.1% with very valid criteria. Meanwhile, the practicality results obtained a teacher response of 95% and a student response of 85.2% which indicates very practical results. The results of the pretest and posttest analysis show that the teaching materials are effective in improving mathematical reasoning, where the teaching materials can help students achieve the minimum completeness criteria both individually and classically, and there is an increase in students' mathematical reasoning with an N-Gain value of 0.24. Therefore, Science, Technology, Engineering, Arts, and Mathematics (STEAM)-based teaching materials can be used as an alternative in facilitating students to develop mathematical reasoning.

Ethnomathematical Exploration of Tegal Traditional Food as Source of Contextual Problems in Problem-Based Learning Model
type: item
description: This study aims to explore the ethnomathematical values found in traditional foods of Tegal and to identify their potential as alternative sources of contextual problems in mathematics learning based on Problem Based Learning (PBL). The research employed a qualitative approach with an ethnographic method through literature review and visual observation using secondary documentation. Data were collected from various written sources and relevant images, then analyzed to reveal the geometric shapes and mathematical concepts embedded within them. The exploration results indicate that six types of traditional Tegal foods, namely tahu aci, bogis poci, olos, alu-alu, kamir, and apem, possess geometric forms that can be linked to concepts of solid geometry, plane geometry, and algebra. These findings provide a foundation for designing contextual problems aligned with the principles of PBL, where students are presented with real-world problems, work collaboratively, and construct meaningful understanding. This study does not measure learning effectiveness but produces a thick description that can serve as a reference for teachers and curriculum developers in integrating local wisdom into mathematics learning.

Culturally Responsive Teaching in Differentiated Learning to Improve Mathematical Communication Ability
type: item
description: This study was motivated by the low mathematical communication ability observed among students, which is partly due to teaching approaches that have not fully accommodated students’ diverse cultural backgrounds and learning needs. The purpose of this classroom action research is to improve students’ mathematical communication ability in differentiated learning through Culturally Responsive Teaching (CRT). The data were collected using questionnaires, observation sheets, and tests in statistics topic, and were analyzed by comparing data from pre-test and post-test results. This study was conducted in 2 cycles in a class of Grade X students at SMAN 14 Semarang with procedures: (1) planning, (2) action, (3) observation, and (4) reflection. The first cycle is related to differentiated-process learning based on learning interests through CRT with the theme of Semarang City Culture, while the second cycle is related to differentiated-process learning based on learning styles through CRT with the theme of Javanese Culture. The results showed that CRT in differentiated learning can improve mathematical communication ability by in the first cycle and in the second cycle. The learning process became more inclusive, with students showing greater confidence in communicating mathematical ideas and engaging more actively in class discussion. This study contributes to the field of mathematics education by integrating cultural responsiveness with differentiated instruction, which can address diverse student needs, foster a meaningful learning environment, and improve mathematical competencies.

Development of Digital Puzzle Based on Indonesian Traditional Houses as Virtual Manipulative Learning Media for Plane Geometry
type: item
description: The gap between the theory of plane geometry and real-life contexts occurs because the media often used only teach procedurally, resulting in weak conceptual understanding among students. Based on this, this research aims to develop a digital puzzle based on traditional houses that is suitable and practical for use as a virtual manipulative medium to bridge contextual understanding toward conceptual understanding. This research used a Research and Development (R&D) design and the 4-D model (define, design, develop, and disseminate) with interview guidelines and feasibility and practicality questionnaires as instruments, which were administered to 25 fourth-grade elementary school students. The results of validation by content and media experts indicate a very feasible category with feasibility percentages of 88% and 97.5%. This media is considered very practical to use, with a practicality percentage of 81.7%. These findings show that Digital Puzzle Media based on Traditional Houses is well-suited for teaching plane geometry in elementary school.

Exploration of the Implementation of Deep Learning Approach in Teaching Mathematics in Secondary Schools
type: item
description: This study explored how mathematics teachers interpret and implement deep learning approaches in classroom instruction and the challenges they encounter. Using a qualitative case study design, data were collected from five teachers through an open-ended online questionnaire and two in-depth interviews. Thematic analysis was conducted following the Miles, Huberman, and Saldaña framework. The findings revealed that teachers view deep learning as a student-centered approach that emphasizes conceptual understanding, critical thinking, and emotional engagement. Teachers employ various strategies such as group discussions, problem-based learning, contextual problem solving, discovery learning, open-ended math projects, game-based assessments, and the CORE model. However, challenges arose in tailoring strategies to meet diverse student needs, managing time constraints, and dealing with limited infrastructure. The study concludes that, although teachers value deep learning, its effective classroom application depends on stronger institutional support and flexible pedagogical models. These findings offer practical insights into how deep learning is interpreted and practiced in Indonesian mathematics classrooms.

From Perception to Error: A Study of Ghanaian Learners’ Errors in Solving Algebra Tasks
type: item
description: The nature of algebraic word problems can make such tasks daunting for learners, and this can be further exacerbated by factors including their perceptions. This study explored Ghanaian Junior High School learners’ perceptions of algebraic word problems, how these perceptions are reflected in their errors, and the factors influencing these perceptions and errors. A sequential explanatory mixed-method design was employed to collect data from 200 learners using a test, followed by semi-structured interviews with six learners: three high performers and three low performers. Stratified random sampling was used to recruit learners for the survey, while purposive sampling was applied in selecting learners for the interview. Data were analyzed using descriptive statistics and thematic analysis. The study found that many learners perceived algebraic word problems as “difficult,” “confusing,” or “tricky,” which lowered their confidence and willingness to engage with such tasks. These negative perceptions were closely linked to high rates of comprehension errors (misinterpreting unknowns, 77.5%), transformation errors (reversing subtraction order, 60.5%), and process skill errors (ignoring negative signs, 73.5%). Influential factors included inadequate individualized support from teachers, limited practice, unavailability of textbooks, and large class sizes. It is suggested that mathematics teachers use small-group learning to provide targeted attention and integrate algebraic word problems into daily lessons and assessments. Heads of schools should liaise with Parent-Associations (PAs) to provide adequate textbooks for learners and split classes into streams to reduce overcrowding.

Relational Thinking Test Instrument Analysis: Transition from Arithmetic to Algebra
type: item
description: Relational thinking, a cognitive approach bridging arithmetic thinking and algebraic thinking, has been developed by numerous researchers through mathematics learning processes to address students' difficulties in learning algebra. This study aims to develop a relational thinking test instrument for students and conduct both quantitative and qualitative analyses to measure relational thinking abilities in a valid and reliable manner. The research methodology adapts the development model proposed by Gall and Borg (2003) regarding the process of developing and validating products (test instruments), involving 64 seventh-grade students. Data analysis involved validity and reliability tests as well as analysis of students' written responses. The results indicate that the test instrument is valid (except for test item P8) and reliable, with a coefficient of α = 0.69 (high). Revisions were made to several items that were invalid or less valid based on quantitative and qualitative analysis. The revised instrument can be considered a good relational thinking test instrument, though it is recommended to support it with non-test results (such as interviews) to enhance accuracy and observe students' thinking consistency.

Reducing Math Anxiety and Strengthening STEM Pathways: A Conceptual-Pedagogical Approach
type: item
description: The development of skills among students in STEM fields is not only a pressing concern in countries like India and South Africa — it is a universal need. In an increasingly technology-driven world, building cognitive strength, attention capacity, and analytical reasoning from an early age has become a foundational requirement in education. While both India and South Africa have made progress in schooling, significant challenges remain, particularly in nurturing the critical thinking disposition among learners. This paper compares the two systems to observe visible gaps, especially in high school education, and examines how these gaps begin forming as early as childhood. The idea of learning through the body, particularly through the use of fingers, is explored with the support of Vedic mathematical techniques. A three-stage pedagogical approach is proposed, which not only introduces number concepts at an early age but also builds a bridge between the concrete and the abstract. This organic and tactile method reduces mathematics anxiety and fosters resilience. The Indian school system’s restriction on calculator use until Grade 12 is noted to preserve cognitive engagement, whereas early reliance on calculators in South Africa may unintentionally hinder analytical development. This paper ultimately suggests that using one’s own body as a natural learning tool not only improves numerical fluency but also cultivates a stronger critical thinking disposition, which is essential for solving the larger issue of STEM skill shortages in the future.

type: item
description: Online and e-learning programmes have shifted the power bloc to the learner within their cultural settings. In a case study-based qualitative design, the researchers sampled 40 student-teachers to produce and laminate works of prominent women scientists’ contributions. The data was collected through observations and unstructured interviews. The items were coded on four 7-point Likert scales to represent the planning and design (satisfaction), teaching and learning (reflection), as and through learning (priority), formative assessment (quality), and assessment of virtual class (satisfaction). In qualitative content analysis, the medians predominantly pooled 6 while the modes pooled between 5 and 8 (multimodal). In cases where the median was greater than the mode, we had positive skewness and the reverse was negative skewness. The Spearman’s correlation coefficients showed that only one pair recorded strong positive correlation and two to three pairs recorded strong negative correlations. The chi-square tests for independence showed the null hypothesis was rejected to mean that there were associations among the variables. It was concluded that digital didactics was the central point for the design and use of teaching and learning. It was therefore concluded that digital didactics innovated mathematics instruction and learning.
