Abstract

Cultural integration in education has emerged as a powerful tool for enhancing student engagement and learning outcomes. However, the specific impact of cultural integration on mathematics education, particularly in relation to students' academic achievement and their appreciation of mathematical beauty, has not been thoroughly examined. This study explores the effects of a teaching module that integrates Zapin and Kuda Kepang dances with isometric transformations on these outcomes. Using a quasi-experimental design, the research involved 60 Form Two students from Johor Bahru, divided into treatment and control groups. The module was implemented over five weeks, with data collected through academic performance tests, questionnaires, and semi-structured interviews. Independent t-tests and Mann-Whitney U tests (conducted using SPSS version 21) revealed significant improvements in academic achievement and appreciation of mathematical beauty among students in the treatment group. Thematic analysis of interview data further revealed increased motivation, interest, and emotional connection to mathematics. These findings highlight the potential of integrating cultural elements into mathematics education to foster deeper engagement and academic success, emphasizing the need for innovative teaching approaches in secondary education.

Abstract

The aim of this research is to determine whether Project-Based Learning (PjBL) affects middle school students' ability to solve mathematical problems during the learning process. This research is mix-method research with explanatory sequential design, namely the data is analyzed quantitatively first and continued with descriptive qualitative analysis. The results of the test indicated a t-value of 2.7354 with a p-value of 0.007751 (which is less than 0.05), signifying a significant difference of the experimental group and the control group after the treatment was applied. PjBL has an influence in improving problem solving of middle school students. Students can identify important elements in a problem, create appropriate problem representations, use relevant knowledge and skills to solve problems, and are able to interpret relevant results and conclusions. This study suggests that PjBL provides an impact on meaningful learning experiences and in-depth learning.

Abstract

The removal of forests has become a major challenge for indigenous students in Malaysia called Orang asli. The younger generations of Orang asli need to equip themselves with relevant knowledge to deal with changes within their living environment. However, they faced difficulties during learning such as irrelevant curriculum, lack of materials and inappropriate approaches. A project-based environmental module is constructed which employs the analyze, design, develop, implement and evaluate (ADDIE) instructional model with three projects: the construction of habitat, soil acidity and infiltration of pesticides. This study aimed to develop this module and assess its suitability to inculcate scientific attitudes and noble values among the Orang asli primary six students. The data were collected through validation questionnaires that were given to three validators. The data obtained are further analyzed to identify their improvement towards the module. The validation results show that the module is very feasible (85.83%) to be used. Many opine that this module creates a learning experience for them through scientific reasoning, inquiring, cooperating, and decision-making so that they find the relevancy of knowledge in the Orang asli context. The enhancement of this module provides useful educational guidance to learn environmental knowledge from a scientific perspective.

Abstract

This study compares Malaysian and Korean geometry content in mathematics textbooks to help explain the differences that have been found consistently between the achievement levels of Malaysian and South Korean students in the Trends in International Mathematics and Science Study (TIMSS). Studies have shown that the use of textbooks can affect students’ mathematics achievements, especially in the field of geometry. Furthermore, to date, there has been no comparison of geometry content in Malaysian and Korean textbooks. Two textbooks used in the lower secondary education system in Malaysia and South Korea were referred. The topic of quadrilaterals was chosen for comparison, and the topic’s chapter in the South Korean textbook has been translated into English. The findings show four main aspects that distinguish how quadrilaterals are taught between the two countries. These aspects include the composition of quadrilaterals topics, the depth of concept exploration activities, the integration of deductive reasoning in the learning content and the difficulty level of mathematics problems given at the end of the chapter. In this regard, we recommend the Division of Curriculum Development of the Malaysian Ministry of Education reviews the geometry content of mathematics textbook used today to suit the curriculum proven to produce students who excel in international assessments.

Abstract

This study examined the parental involvement in monitoring their children online learning at foundation level through the parents’ perspectives, challenges and satisfaction. In addition, this study explored the relationship between parent’s perspectives on student’s online learning and parents’ demographic information (number of households, household income, and education level). This study employed a cross-sectional survey design, where a questionnaire was used for data collection. A total of 276 samples were selected randomly from parents who enrolled their children at a foundation center in a selected year. Data of the study were analyzed through descriptive (mean, standard deviation, percentage) and inferential statistics (Sperman’s correlation) using SPSS version 23. The findings of the study showed that majority of the parents have positive perspectives and high satisfactions towards involvement in monitoring foundation students’ online learning at home. The findings also revealed a strong positive correlation between parental perspectives towards involvement in monitoring foundation student’s online learning and household income as well as parents’ education level. The outcome of the study highlighted the parental readiness and awareness in their role in monitoring students’ online learning in tertiary education level while also providing awareness to educators on its importances and challenges in their online learning classes.

Abstract

The Effect of Interactive Media Based on Dynamic Geometry Software with the RME Approach on Improving Critical Thinking in Rotation Material. Objectives: The goal of this research is to examine the effect of using interactive media on Dynamic Geometry Software (DGS), like GeoGebra, along with the Realistic Mathematics Education (RME) technique in improving students’ critical thinking on the topic of rotation in geometry. Methods: The study used both a quantitative approach and a quasi-experimental approach. There were 38 students from SMA Negeri 1 Olahraga Sidoarjo in East Java who took part in this study. The experimental class and the control class consist of 19 students each. The experimental group learned with GeoGebra-based interactive media and the RME method, while the control group learned more traditionally without technology and the RME method. A set of validated test questions was administered before and after the intervention to measure students’ critical thinking skills. Results: There was a significant difference between the two groups’ critical thinking skills. Students in the experimental class were much better at understanding, evaluating, and thinking about geometric rotation problems than students in the control class. Combining GeoGebra and RME helped students understand how rotation works in real life and made them more interested, active, and better at understanding, exploring, and using it in a meaningful way. Conclusion: The RME method and GeoGebra helped students think critically about geometry, especially rotation. These results support the idea that using technology in a way that makes learning mathematics more meaningful, like RME, can help students think more deeply. Teachers should think about using these kinds of strategies to help their students learn mathematics better. Keywords: critical thinking, geogebra, quasi-experimental, RME, rotation.

Abstract

Most mathematics word problems contain real-life context, but not all are relevant to real-life reality. Despite the mathematical solvability of these problems, their contexts may be contrary to the facts in the real world. This study explored the responses of pre-service mathematics teachers while facing the mathematics word problem containing contradictory information within a real-life context. A total of 48 pre-service mathematics teachers from various cohorts participated in this study. The participants were asked to solve a mathematics word problem that was designed to be solvable mathematically but presented a situation that contradicted to real-life context. The findings reveal that while the participants are adept at mathematical procedures, many did not realize and some were confused by the anomalies within the problem context. Only a few of them recognized the contradictory information and stated that the problem was illogical or impossible. This study specifically explores the gap between mathematical solvability and the relevance of real-world contexts in word problems. Most previous research has primarily focused on pre-service teachers’ ability to solve mathematical problems without examining whether they notice the anomalies in the problem’s context. This study emphasizes raising pre-service mathematics teachers’ awareness of the real-life context in mathematics word problems.

Abstract

Students often struggle to identify relevant analog problems when solving new tasks, highlighting the need for teachers to design simple analog problems that serve as scaffolding. This study aims to analyze prospective teachers’ analogical reasoning processes in simplifying complex geometry problems using the Analogical Reasoning in Mathematics (ARM) framework. This qualitative research involved 34 prospective mathematics teachers from a public university in Surabaya, Indonesia. Participants were selected through purposive sampling based on their academic performance and prior coursework in geometry and problem solving. Data were collected through task-based interviews, written work, and observations during problem-simplification activities. The collected data were analyzed thematically, guided by the components of the ARM framework. The results indicate that prospective teachers with varying ability levels employed different analogical reasoning strategies to simplify complex problems through ARM activities. High-ability prospective teachers identified a broader range of student difficulties and adapted the problems into two-step analog problems featuring variations in visual representations, number of circles, and geometric shapes. Conversely, low-ability prospective teachers focused on difficulties related to verbal representation and the need for concrete numerical information, adapting the problems into single, highly simplified analog problems with specific images and numbers. Overall, prospective teachers actively utilized analogical reasoning to design analog problems that addressed student difficulties. Differences in ability were associated with the complexity of adaptation strategies and the depth of difficulty identification, underscoring the importance of training prospective teachers to integrate both approaches to effectively support student understanding.

Abstract

Osteoarthritis (OA) is a musculoskeletal disorder specified as a joint disease that affects mostly human joints worldwide. Total knee arthroplasty (TKA) is performed to restore the affected joint and relieve the symptoms. However, tibial malrotation, which is one of the most common errors in TKA, results in poor function of the implant and pain after the procedure. People with OA often experience limited mobility and cannot accomplish daily tasks. Finite element analysis (FEA) has been widely applied to interpret the biomechanical and kinematic force along the joint and investigate the cruciate ligament’s mechanical behavior. Unfortunately, one of the problems in TKA implants is their malalignment affecting tibial rotation. This study employs FEA to investigate the relationship between tibial malrotation and the consequent displacements and forces in the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL). A subject-specific knee model is used to study the effects of ligament model complexity and simulated ligament wrapping on knee biomechanics and kinematics. Tibial malrotation had a more considerable effect on ACL than on PCL. In terms of ligament forces, both anterior and posterior PCL bundles generated notably greater forces compared with the ACL bundles, with averages of 26823.92 ± 13.32 N and 2796.49 ± 23.98 N, respectively. The displacement of the PCL bundles was also substantial, equaling 26.37 ± 0.01 mm in the anterior and 18.87 ± 0.08 mm in the posterior. Correct implant alignment is essential to avoid overtensioning of the ligament and offers knee joint ligament balance that can restore native knee kinematics.

Abstract

Purpose: This study investigated the conceptions of proof of prospective mathematics teachers’ learning limits, with a particular focus on how these conceptions were manifested in representational activity. Method: A qualitative teaching-research design was used to collect data from 82 first-year prospective mathematics teachers enrolled in a Calculus I course at a public university in Indonesia. The main data were prospective mathematics teachers’ written responses to an ε–δ limit proof task, classroom discussions, and reflective teaching notes. Data was analysed using iterative, thematic coding and constant comparative analysis, following a representational-epistemic framework. Findings: Four qualitatively different conceptions of proof were identified: proof as computation, proof as algebraic procedure, proof as formal display, and proof as logical argument. Most participants used computational or procedural approaches and a small proportion of participants constructed logically coherent deductive arguments. The results indicate that prospective mathematics teachers’ difficulties are not only related to algebraic manipulation but also to understanding the epistemic function of proof in university mathematics. Specifically, ε–δ notation was often taken as a formality of notation rather than as a relational structure for reasoning. Significance: The study adds to research on the secondary–tertiary transition in mathematics education by demonstrating the relationship between prospective mathematics teachers' representational practices and different conceptions of proof. The findings are also relevant to designing introductory calculus instruction to support prospective mathematics teachers’ transition from verifying procedures to deductive justification.
