Abstract

Mental strategies are recognized as an effective approach for solving arithmetic operations such as addition and subtraction. This study focuses on developing and implementing instructional activities aimed at enhancing students' mental strategy skills through the Indonesian Realistic Mathematics Education (IRME) approach. The research employed a design-based methodology involving 2nd-grade students from an Islamic-integrated school in Surabaya. The study followed a research design that emphasizes the development of local instructional theory, encompassing three key phases: the preparatory phase (initial design development), the experimental phase (classroom teaching experiments), and the retrospective analysis phase. Data collection methods included documentation, field notes, and interviews. In the first trial, three instructional activities were conducted. Based on the analysis of the first trial, the number of activities in the second trial was increased to four: "Let's Get Used to Alms Every Day," "Don't Forget Routine Alms This Week," "Set Your Own Pocket Money," and "Let's Give Away Your Alms to Break Mr. Samad’s Fast." These activities were designed to achieve specific mathematical objectives, enabling students to understand and solve addition and subtraction problems using strategies such as skip counting, borrowing, and saving. The retrospective analysis concluded that students successfully learned to perform addition and subtraction operations on both monetary values and ordinary numbers within the designed learning trajectory.

Abstract

This study investigates the impact of integrating both concrete and virtual manipulatives on the mathematics achievement of fifth-grade students across different achievement levels (low, average, and high). Utilizing a quasi-experimental design with pre- and post-tests, a convenience sample of fifth-grade students was randomly assigned to either a control or experimental group. The data collection instruments, consisting of separate pre- and post-tests on the same mathematical concepts, underwent thorough validity and reliability testing. Initial assessments demonstrated that the achievement levels between the control and experimental groups were comparable prior to the intervention. The experimental group received instruction that incorporated both concrete and virtual manipulatives, whereas the control group followed traditional teaching methods. Following a 12-week intervention period, a post-test was administered. The data were analyzed using parametric paired-sample t-tests and one-way ANCOVA, ensuring that all underlying assumptions were satisfied. The findings revealed significant improvements in post-test scores among students in the experimental group, regardless of their initial achievement levels. Although low-achieving students in the control group also showed progress, their gains were less substantial compared to those in the experimental group. This study highlights the potential benefits of incorporating both concrete and virtual manipulatives in fifth-grade mathematics instruction to enhance academic achievement.

Abstract

In mathematics teaching and learning, mathematics tasks embedded in realistic contexts are crucial for developing mathematical concepts, procedures, and the application of mathematical knowledge. Despite this, mathematics teachers often encounter challenges in designing and implementing such realistic mathematics tasks. Therefore, this study aims to construct a learning trajectory to enhance preservice mathematics teachers' abilities to create and implement Realistic Mathematics Tasks (RMTs). Employing a design research methodology, the study comprises three phases: preliminary design, teaching experiment, and retrospective analysis. The data presented in this article are from the first cycle, encompassing all three phases. The research involved four fourth-year preservice mathematics teachers from Sanata Dharma University in Yogyakarta, Indonesia, participating in a preliminary experiment conducted over three months outside their regular coursework. Data were collected through pre-course written tests, observations, interviews, journal reflections, and analyses of the preservice teachers' work. The findings indicate that the learning trajectory effectively raised awareness among preservice teachers about key characteristics of realistic mathematics tasks. This heightened awareness was evident in their reflections and work. Additionally, observations of their teaching practices revealed that preservice teachers valued student reasoning in solving RMTs. However, they faced difficulties in classroom management and guiding students to construct new knowledge actively through their experiences in solving RMTs.

Abstract

The 'Gradual Release of Assistance (GRA) instruction' was implemented among pre-service teachers in a problem-solving course designed to reduce students' resistance to independent problem-solving. This approach aimed to enhance students' heuristic skills, confidence, and attitudes toward problem-solving. The GRA instruction encompassed activities with progressively decreasing levels of instructional support across three stages: the maximum assistance stage, the medium assistance stage, and the independent problem-solving stage. Utilizing an embedded multiple-case design and a simple time-series analysis of six individual cases, this research explored how pre-service teachers applied heuristics and their confidence and attitudes toward problem-solving. The study revealed improvements in heuristic application among cases with high and medium mathematical abilities, as well as increased confidence and positive attitudes toward problem-solving within this cohort. However, there were no notable improvements in using different heuristics among cases with low mathematical ability. The findings discussed the observed changes and consistencies, offering plausible explanations that underscore the significance of GRA instruction in alleviating students' reluctance to engage in independent problem-solving.

Abstract

Financial mathematics is a crucial discipline for students, mainly when taught using real-life contexts such as gold and its share. It can help students develop practical solutions to financial problems. This study aimed to design a financial mathematics task for Vocational High Schools (VHS) that is valid, practical, and demonstrates potential effects utilizing the Pendidikan Matematika Realistik Indonesia (PMRI) approach in the context of gold and its share. The research employed a design research methodology, specifically a development study involving two primary phases: preliminary and formative evaluation. The latter included multiple stages of prototype development, beginning with self-evaluation, then expert review, one-on-one sessions, small group trials, and culminating in a field test. The study was conducted with 44 eleventh-grade accounting students at VHS 1 Jambi City, consisting of 3 students for the one-to-one phase, 6 for the small group phase, and 35 for the field test phase. Data were collected through tests, interviews, documentation, and observations. The findings indicate that the financial mathematics task designed using the PMRI approach, contextualized in gold and its share, was valid, practical, and positively impacted student learning. Students not only developed a deeper understanding of real-world financial issues but also enhanced their decision-making abilities in financial contexts. Additionally, teachers expressed a greater willingness to adopt the PMRI approach in their instruction, suggesting that this context can effectively support the teaching of financial mathematics in vocational high schools.

Abstract

Audiovisual materials have been widely investigated in mathematics education for their capacity to improve learning outcomes and mitigate student disengagement. Therefore, this study aims to evaluate the acceptance of audiovisual materials as instructional aids among eighth-grade students. Adopting a mixed-method approach, the research first involved semi-structured interviews with mathematics teachers to identify key teaching and learning challenges. Based on the insights gained, educational videos were developed, adhering to motivational and didactic criteria. In the final phase, 78 students from a public high school in Ibarra, Ecuador, participated in a Likert-scale survey, guided by the Technology Acceptance Model (TAM), to assess their reception of the videos. The findings revealed that teachers highlighted fear of mathematics, insufficient prior knowledge, and the abstract nature of the content as major obstacles to be addressed. Most students responded positively, considering the videos effective for enhancing their understanding of mathematical concepts and boosting their motivation to learn. This study underscores the potential of audiovisual materials as effective tools to address educational challenges and foster student engagement in mathematics.

Abstract

This study addresses the pressing need to develop critical thinking skills in young learners, which is essential for 21st-century education. Focusing on Indonesian elementary school mathematics teachers, this research provides new insights into the specific challenges they encounter a context that has been underexplored in the existing literature. The primary objective of this study is to identify the barriers these teachers face when integrating critical thinking skills into their mathematics instruction. Utilizing a qualitative approach, the research employs open-ended online surveys, allowing participants to respond to their own words rather than selecting from predefined options. Convenience sampling was used to recruit participants, resulting in a sample of 114 teachers from ten provinces across Indonesia. Data from the surveys were analyzed thematically and inductively using constant comparative methods. The analysis identified that the major obstacles to integrating critical thinking skills into mathematics education were limitations related to time and resources (accounting for 71.34% of identified barriers), along with deficiencies in pedagogical knowledge, confidence, and skepticism about the expected outcomes. The findings of this study offer valuable insights into the considerations necessary for successfully incorporating critical thinking skills into elementary mathematics instruction and highlight the potential for enhancing teacher effectiveness in this area.

Abstract

The concept of slope constitutes a fundamental component of the discourse surrounding linear equations. A subset of students frequently interprets slope merely as an algebraic ratio. This particular context fosters a superficial understanding of slope, as these students typically resort to mechanical memorization of the slope formula. The intent of this research endeavor is to enhance a holistic understanding of the slope concept: physically, geometrically, algebraically; through the deployment of realistic teaching activities. Two students are participants in this research endeavor. The research group initiated a series of questions aimed at assessing their comprehension by delivering a total of six activities, which were systematically designed using the emergent modeling framework central to the educational design principles of Realistic Mathematics Education (RME). These activities are structured to facilitate the students' understanding of the fundamental concept of slope, transitioning from physical properties, through geometric ratios, to algebraic ratios. Subsequent to the investigations and the interviews conducted, the researchers deduce that the utilization of realistic activities significantly enhances students' comprehension of the foundational concept of slope: physical, geometric, algebraic.

Abstract

Students’ learning speed and number sense are critical aspects of mathematics education, yet little is known about how these factors interrelate across different learner profiles. Addressing this gap, this research investigates the characteristics of students’ number sense in relation to their learning speed, providing a novel perspective on tailoring mathematics instruction. This qualitative case study involved 185 8th and 9th students from seven junior high schools across seven sub-districts in Sukabumi, Indonesia, who had previously studied fractions. The research was conducted in three stages: identifying learning speed through IQ scores, self-assessment, and teacher evaluations; administering a diagnostic test to assess number sense; and analyzing the number sense characteristics of representative students from each learning speed category. Findings reveal a comprehensive mapping of learning speeds, highlighting the role of factors such as conceptual understanding, study habits, and mathematical content processing in number sense achievement. Notably, differences were observed among slow, average, and fast learners, suggesting the need for differentiated instructional strategies. The implications of this study emphasize the importance of targeted approaches in mathematics teaching, enabling educators to foster inclusive environments that cater to diverse learning needs. This research contributes a unique methodology for integrating cognitive and practical assessments to better understand and support students’ mathematical development.
