The enhancement of metacognitive abilities and problem-solving skills is essential for effective mathematics instruction. However, these critical components are frequently overlooked in traditional teaching practices. This study addresses the challenges and requirements faced by mathematics educators and explores the integration of constructivist activities in classroom settings. It aims to develop and evaluate the suitability of an instructional model designed to address these issues. Employing a mixed-method approach within a research and development framework, the study gathered data through semi-structured interviews with seven mathematics teachers in Bhutan to identify their instructional challenges. Additionally, two experts from Bhutan and one from Thailand were consulted to provide insights into constructivist teaching methodologies. The content analysis of teacher interviews revealed a predominant reliance on structured, teacher-centered instructional methods, with limited emphasis on fostering higher-order cognitive skills. To bridge this gap, an instructional model emphasizing the development of higher-order thinking was designed. This model incorporates active learning, problem-solving, collaboration, scaffolding, reflection, and self-monitoring, organized into six steps: prior knowledge activation, mediation, internalization, generalization, transfer, and evaluation. The model was evaluated using a 5-point Likert scale, achieving a mean score of 4.33 (SD = 0.70), indicating high levels of appropriateness and acceptability. Furthermore, a pilot test yielded an effective index (EI = 0.51), demonstrating the model's efficacy in fostering metacognitive and problem-solving skills.

Andi Mariani Ramlan, I Ketut Budayasa, Endah Budi Rahaju — Mon, 27 Jan 2025 00:00:00 +0000

Proportional reasoning is a critical component of mathematical competence that should be developed at the senior high school level, as it fosters both foundational and advanced mathematical understanding. Educators frequently encounter variations in proportional reasoning abilities among students, often influenced by individual personality types. However, limited research has specifically investigated the proportional reasoning capabilities of high school students with artisan personality types. This study aims to examine the strategies and approaches utilized by students with Artisan Personality Types (APT) in solving trigonometric comparison problems. Employing a qualitative descriptive methodology within a case study design, the research focused on high school students identified as having APT. Data were collected using proportional reasoning tasks, the Keirsey Personality Type Questionnaire, and structured interviews. The analysis was conducted qualitatively, with findings categorized based on established indicators of proportional reasoning. Results indicate that APT students demonstrate the ability to address proportional reasoning problems related to covariation, ratios, and proportions, employing distinct strategies and logical reasoning. Nevertheless, instances of both correct and incorrect responses were observed, often stemming from misinterpretations of the problem context. These findings provide valuable insights for future studies aimed at designing targeted instructional strategies and developing learning tools to enhance the proportional reasoning skills of students with APT.

Sri Winarni, Kamid, Jefri Marzal, Asrial — Mon, 27 Jan 2025 00:00:00 +0000

Numeracy skills are essential for prospective mathematics teachers as they bridge mathematical concepts with real-life applications. However, many prospective mathematics teachers face challenges in applying these concepts to practical situations. This study aims to analyze the conceptual and procedural errors made by prospective mathematics teachers when solving numeracy problems within the context of "Save Our Water." A descriptive research design was employed, utilizing a numeracy test adapted from the Minimum Competency Assessment (MCA) and semi-structured interviews as research instruments. The study involved 30 prospective mathematics teachers from the University of Jambi, Indonesia. The findings revealed that conceptual errors primarily stemmed from reliance on rote memorization of formulas without a deeper conceptual understanding. Procedural errors were attributed to difficulties in unit conversion, incorrect formula application, and improper manipulation of formulas. To address these issues, the study recommends incorporating contextual approaches, problem-based learning, and project-based learning strategies that connect mathematical concepts to real-world contexts. Additionally, the use of visual aids, such as diagrams and 3D models, is suggested to enhance conceptual understanding and strengthen the connection between abstract concepts and practical applications. Future research should investigate the effectiveness of these instructional approaches in improving numeracy skills and enhancing the teaching readiness of prospective mathematics teachers.

Pre-service mathematics teachers’ proof comprehension through Toulmin’s argumentation model

Angel Mukuka, Benjamin Tatira — Wed, 26 Feb 2025 00:00:00 +0000

The comprehension of mathematical proofs by preservice mathematics teachers is vital for their ability to effectively teach mathematical reasoning. Despite its importance, existing research reveals a significant gap in preservice teachers’ understanding and application of formal proof methods, especially in the context of mathematical argumentation. This study aims to address this gap by examining how preservice teachers construct mathematical proofs, using Toulmin’s argumentation model as a framework. A qualitative exploratory case study design was adopted, involving written proofs from 72 third-year preservice teachers at a South African university, supplemented by task-based interviews with nine participants. The findings indicate that 62.5% of the participants were able to construct correct direct proofs, and 61.1% applied the contraposition proof method correctly. However, only 30.6% produced valid proofs using the contradiction method. Further analysis uncovered notable gaps in essential components of proof construction, such as warrants, backing, and rebuttals, particularly when dealing with tasks requiring contraposition and contradiction methods. While many participants (62.5%) demonstrated procedural fluency in direct proofs, 31.9% failed to provide explicit definitions or logical precision, suggesting a superficial engagement with proof construction. These results highlight the need for teacher education programs to emphasize a deeper conceptual understanding of proof structures, which is crucial for preparing preservice mathematics teachers to foster reasoning and argumentation skills in their future classrooms.

Students’ financial literacy in math classroom: Insights into financial awareness

Fri, 07 Feb 2025 00:00:00 +0000

The current generation of young people faces significant financial challenges in an increasingly volatile global economy, highlighting the need for enhanced financial literacy education. While the OECD has recommended the integration of financial literacy into school curricula, a notable gap exists in the development of age-appropriate financial literacy content that aligns with students’ cognitive and developmental stages. This study addresses this gap by evaluating students’ financial literacy knowledge, with a particular focus on integrating financial concepts into mathematics education. Specifically, the research targets financial topics that are accessible and relatable to upper elementary school students, exploring how these concepts can be integrated into existing mathematics curricula. The study involved students from grades 4, 5, and 6, with data collected through interviews that were transcribed and analyzed using NVIVO software. Findings indicate that topics such as exchange rates, foreign currencies, cash transactions, and digital payment systems resonate with students' existing knowledge and personal experiences. Furthermore, the study underscores the importance of introducing foundational personal financial management skills, such as distinguishing between needs and wants and promoting saving habits, from an early age. However, it also highlights that more complex financial concepts, including regulatory frameworks, consumer protection, and data security risks, are not developmentally appropriate for elementary students. The results of this research offer valuable insights into the practical integration of financial literacy into mathematics classrooms, with potential implications for curriculum development. These findings contribute to the growing body of knowledge on financial literacy education, providing a basis for selecting relevant financial topics for school curricula and fostering a more financially literate future generation.

Wilda Syam Tonra, Didi Suryadi, Endang Cahya Mulyaning, Kusnandi — Wed, 26 Feb 2025 00:00:00 +0000

The limit of function as one of the core materials in differential calculus will influence the understanding of subsequent material for the derivative and integral. Several studies on limits show that students still experience learning obstacles or difficulties in solving limit problems. A learning obstacle is a condition that limits the acquisition of new knowledge by students during the learning process, potentially causing difficulties in the learning process. There are 3 types of learning obstacles, namely ontogenic obstacles, didactical obstacles, and epistemological obstacles. This research aims to identify learning obstacles in studying 4 sub-contents of function limits. This research is a qualitative approach with the framework of didactical design research (DDR). The participants are 26 students in mathematics education in semester 1 at Universitas Khairun. Data collection through a written test that consists of 4 essay questions. Students' test answers were corrected using holistic scoring guidelines with 4 different scoring categories. The total score of each participant will be grouped into three criteria of ability. The data analysis is qualitative and consists of three steps: data reduction, data presentation, and conclusions. The findings are the dominant learning obstacle based on the content is the formal definition. The learning obstacles that appeared are the epistemological obstacle, psychological ontogenic, instrumental ontogenic, and conceptual ontogenic. Further research is needed to develop a hypothetical learning trajectory and didactical design that can reduce learning obstacles that occur in the learning process.

Children with cochlear implants face cognitive and linguistic challenges, particularly in the relationship between auditory perception and mathematical cognition. While auditory rehabilitation has advanced, there is a gap in understanding how integrating mathematical problem-solving with language rehabilitation can improve both cognitive and linguistic outcomes for these children. This study explores the potential of structured mathematical interventions to enhance cognitive flexibility, numerical reasoning, and verbal communication. The research was conducted in multiple phases, each increasing in complexity to assess cognitive and linguistic changes under various intervention conditions. Pre-intervention assessments compared cognitive and linguistic performance through auditory and verbal tests, quantitative evaluations, and real-time speech monitoring. The intervention involved structured mathematical modules combining arithmetic and logical reasoning with verbal learning, alongside multisensory approaches to integrate auditory and visual stimuli. Post-intervention analysis utilized statistical methods including χ² for categorical data, ANOVA for intra-subject variations, and t-tests for inter-group comparisons. Results revealed significant improvements in cognitive adaptability (χ² = 29.41, p ≤ 0.001) and numerical thinking, with enhanced logical sequencing, arithmetic operations, and spatial structuring. Speech comprehension showed a marked shift from predominantly gestural and visual communication (χ² = 12.36, p ≤ 0.01) to active verbal responses to abstract mathematical concepts (p ≤ 0.05, Cohen’s d = 0.82). Additionally, there was a 1.5-fold increase in multi-sentence responses (p ≤ 0.05), indicating improved linguistic processing skills. These findings emphasize the importance of incorporating mathematical thinking into auditory-verbal therapy, redefining problem-solving as a dual-mode intervention that enhances both cognitive and linguistic development. Educational programs for children with cochlear implants should integrate mathematical foundations, such as spatial arithmetic and logical reasoning, to support linguistic adaptation and bridge numerical abstraction with verbal comprehension in rehabilitation.

Javanese folklore with moral values: An impactful context in learning relations and functions

Thu, 27 Feb 2025 00:00:00 +0000

Indonesia, particularly the Java region, is home to a wealth of folklore rich in moral teachings. Among these, the story of Rama and Sinta is one of the most prominent, and upon initial investigation, it reveals an underlying presence of mathematical concepts, particularly relations and functions. Despite this potential, there is a lack of research on integrating such cultural elements into the teaching of mathematics. This study aims to fill this gap by exploring the use of the Rama and Sinta narrative as a contextual tool for teaching relations and functions. Following the design research method within the Ethno-Realistic Mathematics Education (Ethno-RME) framework, we developed instructional materials for seventh-grade students at a public school in Magelang, Central Java, Indonesia. These materials, consisting of both student and teacher books, were designed to contextualize the mathematical concepts of relations and functions within the cultural narrative. The resulting learning trajectory, consisting of five interconnected activities, not only deepened students' understanding of the mathematical concepts but also reinforced the moral lessons embedded in the folklore. This paper details the development process, implementation, and outcomes of this culturally responsive approach, contributing valuable insights into the integration of local cultural narratives with core mathematical concepts to enhance the learning experience.

A praxeological analysis of linear equations in Indonesian mathematics textbooks: Focusing on systemic and epistemic aspect

Dilham Fardian, Didi Suryadi, Sufyani Prabawanto — Thu, 27 Feb 2025 00:00:00 +0000

Educational research has consistently highlighted that learning obstacles stem not only from the design of learning situations but also from curriculum structures and textbooks, which are pivotal learning resources. Despite the growing body of literature, limited studies focus on the specific challenges posed by the design of learning materials, particularly in early algebra within the Indonesian context. This study addresses the gap by analyzing the grade VII mathematics textbook in the Merdeka Curriculum, with a focus on linear equations with one variable, to uncover learning obstacles in early algebra. Utilizing Didactical Design Research (DDR), a qualitative approach, the research examines the praxeological components of the textbook—tasks (T), techniques (τ), technology (θ), and theory (Θ). The findings indicate three primary categories of learning obstacles: ontogenic, epistemological, and didactic. Notably, the analysis reveals that the design of linear equation content in the textbook is non-systemic and lacks epistemic coherence, posing significant challenges for learners. This study contributes to the understanding of curriculum design by identifying specific obstacles in the Merdeka Curriculum's grade VII mathematics textbook and underscores the need for more systematic and epistemically aligned textbook development. Future research should extend this analysis to other textbooks across various grade levels to determine if these findings are consistent within the broader curriculum framework.

Pre-service teachers’ perspective toward problematic word problems

Abolfazl Rafiepour, Zohreh Khazaie, Lieven Verschaffel — Fri, 07 Feb 2025 00:00:00 +0000

Despite extensive research indicating that students often fail to apply real-world knowledge and common sense when solving word problems, the underlying causes remain underexplored. Teacher behavior and instructional methods are potential factors contributing to students' tendency to provide unrealistic answers to such problems. The current study aims to address this gap by examining the cognitive processes and perspectives of pre-service teachers when solving problematic word problems. A group of 146 pre-service teachers (97 females, 49 males) in Iran participated in the study, which consisted of two phases. In the first phase, participants were given three problematic word problems to solve and were subsequently asked to evaluate four different student responses. A significant correlation was found between the participants' responses in the initial test and their evaluations in the second phase. In the second phase, the study employed a phenomenographic approach to explore the thinking processes and perspectives of the pre-service teachers while solving the problems. The analysis of interview data led to the identification of two primary categories of unrealistic problem-solving: "inattention" and "ignoring." In the "inattention" category, the problem solver fails to recognize the relevance of real-world knowledge, while in the "ignoring" category, the solver acknowledges real-world factors but deliberately chooses not to integrate them into the solution. In the end, a model of unrealistic problem-solving is proposed and discussed, with implications for teacher training and pedagogical practices.

The potential problem to explore students’ functional thinking in mathematical problem-solving

Luthfiana Tarida, Mega Teguh Budiarto, Agung Lukito — Mon, 03 Mar 2025 00:00:00 +0000

Many studies have reported that functional thinking plays a crucial role in mathematical problem-solving, particularly in fields requiring analytical reasoning, such as maritime studies. However, existing research has yet to comprehensively explore the specific task characteristics that effectively stimulate functional thinking in mathematical problem-solving, particularly among maritime students who must apply these skills in solving safety-of-life problems at sea. Addressing this gap, the present study investigates the potential of mathematical tasks in fostering functional thinking among second-semester students enrolled in the Deck Officer Program in Indonesia. The study involved three students with different mathematical abilities, who were given problem-solving tasks. Their responses were observed, recorded, and analyzed based on their written work. The findings reveal that non-routine problems involving functional situations—where students generalize relationships between varying quantities to determine function rules—effectively promote functional thinking. This is evidenced by the emergence of key functional thinking components, including problem identification, data representation, pattern recognition, covariational and correspondence relationships, and the evaluation of generalization rules. These results contribute to the development of research instruments in mathematics education and provide valuable insights for researchers and educators seeking to enhance functional thinking through task design.
