The Effectiveness of Discovery Learning on Mathematical Reflective Thinking Skills Based on the Level of Learning Independence of High School Students
type: item
description: Research on mathematical reflective thinking skills has generally focused on improving learning outcomes through various instructional models. However, limited attention has been given to examining the role of learning independence as a moderating variable that may influence the effectiveness of the Discovery Learning model, particularly in the topic of Systems of Linear Equations in Two Variables (SPLDV). Therefore, this study aims to evaluate the effectiveness of the Discovery Learning model in enhancing the mathematical reflective thinking skills of senior high school students by considering learning independence as a moderating variable. This study employed a quantitative approach using a non-equivalent control group design, involving an experimental group taught through the Discovery Learning model and a control group taught using the expository learning model. Data were collected using a mathematical reflective thinking test and a learning independence questionnaire, both of which were validated and demonstrated satisfactory reliability. Data analysis included descriptive statistics, normality and homogeneity tests, and hypothesis testing using an independent-samples t-test, N-gain analysis, and two-way ANOVA. The results showed that the two groups had comparable initial abilities. However, after the intervention, a statistically significant difference was found, with the experimental group achieving higher post-test scores and greater N-gain improvement than the control group. Furthermore, students' mathematical reflective thinking skills differed significantly according to their level of learning independence, with students demonstrating high levels of learning independence achieving better performance. The interaction between the learning model and the level of learning independence was also found to have a significant effect on students' mathematical reflective thinking skills. These findings indicate that the Discovery Learning model is an effective instr…

A Cross-Sectional Study on the Relationship Between Problem-Solving Ability and Types of Student Errors in Integral Calculus
type: item
description: Many undergraduate students still experience difficulties in solving integral calculus problems because learning tends to emphasize procedural manipulation rather than conceptual understanding. Previous studies have identified various types of errors in integral calculus; however, limited research has simultaneously examined the relationship between students’ problem-solving ability (PSA) and specific error types based on Newman’s Error Analysis (NEA) in integral calculus contexts. Therefore, this study aimed to analyze students’ PSA, identify the dominant types of errors in solving integral calculus problems, and examine the relationship between PSA and NEA error types. This study employed a cross-sectional descriptive-correlational design involving 74 undergraduate students enrolled in an Integral Calculus course at a university in Indonesia. Data were collected using an integral calculus problem-solving test designed based on Krulik and Rudnick’s problem-solving indicators and analyzed using Newman’s Error Analysis (NEA). Descriptive statistics were used to determine students’ PSA levels and dominant error types, while Spearman’s rho correlation test was applied to examine the relationship between PSA and NEA scores. The findings revealed that students’ PSA generally fell into the moderate category. Transformation error emerged as the most dominant error type, followed by process skill and comprehension errors, while reading and encoding errors were not observed. Transformation errors mainly occurred when students selected inappropriate integration techniques, such as applying substitution instead of integration by parts. Furthermore, the analysis showed a strong negative correlation between PSA and NEA scores , indicating that students with higher problem-solving ability tended to make fewer conceptual and procedural errors. These findings suggest that students’ difficulties in integral calculus are closely related to limitations in conceptual understanding, str…

Analysis of Students' Mathematical Communication Skills in Terms of Student Resilience at BAN KALISA School Thailand
type: item
description: This study aims to analyze students’ mathematical communication skills based on their level of academic resilience in solving fraction-based word problems at Ban Kalisa School, Thailand. A descriptive qualitative approach was employed involving 20 fifth-grade students selected through purposive sampling. Data were collected using a resilience questionnaire, a mathematical communication test, and semi-structured interviews, and analyzed through data reduction, data display, and triangulation. The results show that 55% of students were classified as having moderate resilience, 35% high resilience, and 10% low resilience. Students with high resilience achieved the highest communication performance and demonstrated systematic problem-solving procedures, clear reasoning, and accurate use of mathematical symbols. In contrast, students with moderate resilience were able to obtain correct answers but provided limited explanations, while low-resilience students showed difficulties in both conceptual understanding and communication, often presenting incomplete procedures. These findings indicate that academic resilience significantly influences students’ mathematical communication skills, particularly in terms of persistence, clarity of explanation, and the ability to articulate reasoning. Therefore, resilience should be considered an essential factor in supporting the development of effective mathematical communication.

Development of Ethnomathematics-Based Adventure Pocket Book with Nusantara Cultural Context to Enhance Numeracy Literacy
type: item
description: Students’ numeracy literacy skills are still not optimal, as students tend to rely on procedural problem-solving and experience difficulties in analyzing mathematical problems in real-world contexts. In addition, there is currently a lack of teaching innovations that integrate ethnomathematics and pocket books to enhance numeracy literacy.This study aims to develop an ethnomathematics pocket book with an adventure theme in the Nusantara culture to enhance students' numeracy literacy. This study uses the 4D (Define, Design, Develop, and Disseminate) development model. The research subjects consisted of 31 seventh-grade students at a public junior high school in Semarang. Data were collected through interviews, tests, and questionnaires, and analyzed both descriptively and qualitatively. Interviews were used to obtain information, tests were used to measure students’ numeracy literacy, and questionnaires were used to measure level of feasibility, readability, and student response. The results show the pocket book received a score of 91,05% on the feasibility test meeting the very feasible, a score of 87.84% on the readability meeting the easy to understand, and received a score of 96% on the student response meeting the excellent response. Pocket book also effectively enhance numeracy literacy based on the result of the individual completeness test and proportional level of mastery. The results of this development demonstrate that the adventure-themed ethnomathematics pocket book in Nusantara culture is capable of supporting the enhance of numeracy literacy and is feasible for application in mathematics learning. This research developed an ethomathematics-based adventure pocket book set in the cultural context of the Nusantara, contributes to cultural innovation in mathematics, encouraging students' cognitive development.

Analysis of Probabilistic Critical Thinking Skills of Students with High Mathematical Resilience
type: item
description: Probabilistic critical thinking skills are essential for students to master. Previous studies have generally examined mathematical critical thinking based on cognitive abilities, resulting in a gap in the literature regarding how students’ profiles of probabilistic critical thinking are viewed from an affective perspective, namely, mathematical resilience. The purpose of this study is to analyze the probabilistic critical thinking skills of students with high mathematical resilience. This study is a qualitative research conducted on students of the Mathematics Education Study Program, Faculty of Mathematics and Natural Sciences, Semarang State University, with the research subjects being students of the Mathematics Education Bachelor's Program, Faculty of Mathematics and Natural Sciences, Semarang State University, in the second semester of the 2024/2025 academic year. There were three research subjects with high mathematical resilience. Data collection was conducted through tests, interviews, and questionnaires. Data were analyzed using: (1) data reduction; (2) data display; and (3) conclusion drawing/verification, while data validity was determined through triangulation, namely by comparing test results with interview results, as well as comparing the results of the research subjects. The results of this study indicate that the probabilistic critical thinking ability of subjects with high resilience meets the indicators of focus, situation, inference, and overview. However, they are still unable to meet the indicators of reason and clarity. The suggestion is that students need reinforcement in giving reasons for each step in problem-solving, as well as in providing further explanations when concluding. Theoretically, these findings enrich the literature on probabilistic critical thinking by integrating the affective dimension of mathematical resilience. Practically, these results serve as a guide for educators in designing learning interventions explicitly aimed a…

Didactic Design Research on Two-Dimentional Shape Materials Based on Learning Obstacles in Grade VII Mathematics Learning
type: item
description: Geometric shapes are a prerequisite for achieving Phase D learning outcomes in the assessment criteria. However, difficulties were observed among Grade VIII at one of Junior High School in Semarang. The students were unable to solve problems related to geometric shapes in contextual or unconventional problems. This indicates that the students are experiencing learning difficulties with geometric shapes. Learning barriers describe the limitations individuals experience in understanding or mastering a concept within a learning topic. Therefore, this study was conducted to analyze students’ learning barriers in plane geometry, which will then serve as the basis for developing a didactic design in the form of instructional materials for plane geometry. The research subjects were 8 eighth-grade junior high school students and 1 mathematics teacher. This study employed a qualitative approach using the Didactical Design Research (DDR) methodology, which consists of three stages of analysis: (1) analysis of the didactic situation, (2) metadidactic analysis, and (3) retrospective analysis. This study focused on the analysis of the didactic situation. Learning barriers were analyzed through the results of the respondents’ ability tests, interviews, and observations of the learning process. The barriers identified were: a) Epistemological Barriers, where the subjects did not fully understand the concepts of area and perimeter; b) Ontogenetic Barriers, where the subjects did not master the prerequisite material; c) Didactic Barriers, where the learning process only included didactic situations in the form of action situations. The identified learning barriers were subsequently used as the basis for developing a didactic design. The didactic design, developed based on the learning trajectory while considering the identified learning barriers, was then validated by two supervising lecturers and two mathematics teachers from the school where this research was conducted.

Development of Canva-Based Student Worksheets (LKPD) to Support Students’ Mathematical Communication Skills
type: item
description: Mathematical communication skills remain low, particularly in expressing ideas, using representations, and constructing logical arguments. Previous studies on Canva-based Student Worksheets (LKPD) mainly emphasized visual attractiveness and learning motivation, while the integration of mathematical communication indicators remains limited. This study aimed to develop a Canva-based LKPD integrated with a Problem-Based Learning (PBL) approach and examine its validity, practicality, and effectiveness in supporting students’ mathematical communication skills. The study employed a Research and Development (R&D) method using a modified 4D model consisting of Define, Design, and Develop stages. The participants were 30 eleventh-grade students from a public senior high school in Indonesia. Data were collected through validation sheets, mathematical communication tests, observation sheets, and questionnaires. The results showed that the LKPD was very valid, very practical, and moderately effective with an N-gain score of 0.48. These findings indicate that Canva-based visual-static LKPD can support mathematical communication in mathematics learning.

Culture-Based AKM Contexts with Ethnomathematical Research Findings of the Gravestone Industry
type: item
description: Ethnomathematics research has primarily focused on exploring mathematical elements in culture and their application in learning. However, the use of local culture as context in the Minimum Competency Assessment (AKM) questions that measure students’ numeracy literacy skills remain limited and need to be further developed. In fact, the AKM framework identifies the socio-cultural context as one of the contexts for question development. This study aims to identify mathematical elements within the kijing (gravestone) industry (including tradition, tools, materials, production, distribution, and installation) to serve as context for AKM questions development using the Research and Development (R&D) method with the 4D model (Define, Design, Develop, Disseminate). In the Define stage, an ethnographic exploration was conducted through interviews and observations using maximal variation sampling, involving business owners, employees, and the community. The research data were transcribed, coded, and analyzed using source and technique triangulation based on industrial sub-topics. The resulting interpretations were mathematically analyzed in reference to the 2023 AKM framework. A key strength of this research lies in the credibility of the mathematical interpretations, which were evaluated by three high school mathematics teachers acting as raters through inter-rater reliability testing to ensure objectivity and strong consensus regarding the identified mathematical elements. The results identified mathematical elements across four domains (numbers, geometry, algebra, and data and uncertainty) and 27 learning progressions within the AKM framework. The Design stage involved analyzing the intersections and interconnections between domains, sub-domains, and learning progressions across various cultural contexts, resulting in six stimulus sets. The Develop stage encompassed the creation of 17 numeracy literacy items, which were validated by two expert lecturers; the results were c…

Patterns of Mathematical Creative Thinking Process Based on Learning Styles in Graph Theory Learning
type: item
description: Graph theory demands creative problem-solving skills, but students still experience difficulties in producing solutions. Although learning styles have been widely studied in mathematics education, studies examining their influence on students' mathematical creative thinking processes in graph learning are still limited. This research aims to identify the characteristics of the mathematical creative thinking process based on learning styles in graph learning. The research uses a qualitative approach with test instruments, questionnaires and interviews. Based on the results of the questionnaire, six types of learning styles were obtained, namely visual, auditory, read/write, kinesthetic, combined auditory–kinesthetic, and combined read/write–kinesthetic. Subjects were selected using purposive sampling with one student taken for each type of learning style so that the total number of subjects was 6 students. The data analysis technique uses an interactive analysis model consisting of data collection, data reduction, data presentation, and drawing conclusions. The results of the study indicate that students with various learning styles exhibit almost the same pattern of creative thinking processes in solving graph theory problems. This similarity can be seen in the preparation stage where the problem information has not been written completely, the incubation and enlightenment stages where they still have difficulty understanding and solving the concepts of bipartition graphs and isomorphic graphs, and the verification stage which shows that subjects tend to only re-check the answers they understand so that it depends on the fulfillment of the illumination stage. Thus, this pattern of mathematical creative thinking processes is a consideration for lecturers in providing appropriate learning strategies based on the learning styles of students.

description: The lack of mathematics instructional materials integrating local culture has made geometry learning remain abstract and less contextual for students. In addition, the development of ethnomathematics-based student worksheet utilizing Pontianak local culture in quadrilateral and triangle topics is still limited. This study aimed to develop a valid and practical ethnomathematics-based student worksheet rooted in Pontianak local culture for seventh-grade students. The study employed a Research and Development (R&D) method using the Plomp model, consisting of preliminary research, prototyping, and assessment phases. Product validity was evaluated by six validators, including two content experts, two media experts, and two language experts, using content validity measured through Gregory’s Index. The practicality test involved 30 seventh-grade students and one mathematics teacher at a public junior high school in Sungai Kakap in the 2023/2024 academic year using user response questionnaires. The results showed that the developed student worksheet achieved a validity coefficient of 1.00, categorized as high validity in content, media, and language aspects. The practicality test obtained a percentage score of 82.72%, categorized as very practical.

Digital Trigonometry Worksheets: Integrating Computational Thinking and Palembang Local Wisdom to Support Students’ Numeracy Skill
type: item
description: Results from international assessments and previous studies indicate that students’ numeracy skills remain low, particularly in understanding trigonometric ratios and applying them to real-life situations. Computational Thinking (CT) has the potential to support numeracy skills by enabling students to solve problems logically, systematically, and efficiently. This condition is attributed to limited learning innovation. In addition, the integration of Palembang local wisdom contexts can make learning more meaningful by connecting mathematical concepts to students’ real-life experiences. This study aims to develop digital worksheet for trigonometry based on CT with Palembang local wisdom that is valid, practical, and effective in enhancing numeracy. Using design research method with development studies type, the stages consisted of preliminary research, development/prototyping, and assessment. The subjects were 34 tenth-grade students from one of the Madrasah Aliyah Negeri (MAN) in Palembang. Data were collected through validity and practicality questionnaires, as well as pretests and posttests. Results showed a validity score of 94% (very valid) and practicality of 92% (very practical). Moreover, the Wilcoxon Signed-Rank Test revealed a significant difference between students’ pretest and posttest numeracy scores (Asymp. Sig. = 0.000 < 0.05), indicating that the worksheet effectively supports students’ numeracy skills. Thus, the developed digital worksheets are valid, practical, and effective. Future research may test this on larger samples to verify consistency of results.

Integration of Ethnomathematics-Project-Based-Learning to Enhance Understanding of Geometric Transformations
type: item
description: Transformation geometry is an important topic in mathematics education. However, undergraduate instruction is often abstract and focused on procedures, which limits students’ conceptual understanding. Project-Based Learning and ethnomathematics are known to support meaningful learning. Nevertheless, studies that integrate ethnomathematics into a Project-Based Learning framework for teaching transformation geometry in mathematics education programs are still limited. This study aims to develop and evaluate an ethnomathematics-based PjBL model to improve students’ understanding of transformation geometry. The research employed a research and development (R&D) approach using the ADDIE model, encompassing the Analysis, Design, Development, Implementation, and Evaluation stages. The study was conducted with second-year undergraduate students enrolled in a Transformation Geometry course in the Mathematics Education program at Universitas PGRI Palembang. Ethnomathematical contexts drawn from local cultural practices, such as weaving patterns, wood carving motifs, and traditional architecture, were integrated into project-based learning activities. Data were collected through expert validation sheets, pretest–posttest instruments, observation sheets, and student response questionnaires. The results indicate that the developed learning model is valid, as evidenced by expert assessments of content, pedagogy, and media; practical, based on high levels of implementation and positive student responses; and effective, as shown by significant improvements in students’ transformation geometry learning outcomes.

Word-Problem Solving Instruction and Motivation: Influences on Mathematics Performance, Self-Efficacy, and Self-Regulated Learning in Secondary Students
type: item
description: Although word problem-solving is widely recognized as central to mathematics education, existing intervention studies predominantly focus on cognitive outcomes, with limited empirical examination of non-cognitive variables such as self-regulated learning, self-efficacy, and the moderating role of students’ motivational orientation within experimental designs. This study investigates the influence of a word problem-solving (WPS) intervention on secondary school students’ mathematics performance, SRL, and self-efficacy, while examining the interaction effect of intrinsic and extrinsic motivation. A quasi-experimental pretest–posttest control group design was employed, involving 128 eighth-grade students from a private secondary school in Indonesia who were assigned to either a WPS class or a conventional problem-solving class. Mathematics performance was measured using an essay-based problem-solving test, while motivation, SRL, and self-efficacy were assessed through self-report questionnaires. Instrument validity was established through expert judgment and item–total correlation analysis, and reliability was confirmed using Cronbach’s alpha coefficients. Data were analyzed using multivariate analysis of covariance (MANCOVA), controlling for pretest scores, and effect sizes were calculated to determine the magnitude of the effects. The results indicate significant improvements across all dependent variables, with the WPS intervention demonstrating larger effect sizes (0.106 < η² < 0.650) than motivation alone (0.059 < η² < 0.243). Intrinsically motivated students benefited more from the intervention, exhibiting greater gains in self-regulation, self-efficacy, and mathematics performance than their extrinsically motivated peers. A significant interaction between instructional approach and motivation suggests that students’ motivational orientation influences intervention effectiveness. Despite its limitations, this study highlights the importance of integrating cogniti…

Early Numeracy Skills as Predictors of Numeracy Assessment Performance: A Mixed-Methods Study Using the Early Grade Mathematics Assessment Framework
type: item
description: The 2018 PISA results show that Indonesian students' numeracy score is 379, far below the OECD average of 489. This score places Indonesian students' numeracy skills at the lower level (level 1 out of 6) where students are still far from the minimum competency level required to participate in modern society. Meanwhile, students' early numeracy skills are the foundation for further numeracy skills. Therefore, this study aims to analyze the influence of early numeracy skills on the minimum numeracy competency assessment and examine how children's thinking processes in understanding numeracy concepts that are given using the Early Grade Mathematics Assessment framework. This study uses the explanatory sequential mixed method design. A total of 18 second-grade students of SDN 218/IV Jambi City participated in the early numeracy assessment using the Early Grade Mathematics Assessment (EGMA) instrument and the numeracy Minimum Competency Assessment (MCA/AKM) phase A instrument. The linear regression results showed that early numeracy skills significantly influenced the results of the numeracy MCA (p=0.039) with a moderate contribution of 24.1%. Through in-depth interviews and observation, information was obtained that family involvement, the use of concrete objects, and counting strategies using physical methods have an important role in shaping children's numeracy skills. Integration of these findings emphasizes the importance of strengthening early numeracy skills with a concrete operational approach and the role of the learning environment in strengthening the numeracy skills of early grade students in elementary school.

Exploring Mathematical Literacy Domains Through Banggai Yam Agricultural Practices: An Ethnographic Ethnomathematics Study
type: item
description: Ethnomathematics provides a meaningful approach to connecting mathematical concepts with learners’ cultural contexts; however, empirical evidence linking agricultural practices with mathematical literacy domains remains limited. This study aims to explore mathematical structures embedded in Banggai yam farming practices and examine their relevance to mathematical literacy development. This research employed a qualitative ethnographic approach conducted in Banggai Islands Regency, Indonesia. Data were collected through participant observation, in-depth interviews with farmers and traders, and documentation of farming activities. Data were analyzed using domain, taxonomic, and componential analysis to identify cultural categories and their underlying mathematical structures. The findings reveal that Banggai yam farming involves systematic mathematical reasoning reflected in local and formal measurement systems. Farmers use traditional units such as belek (≈150 seed pieces) to estimate planting needs and land area, demonstrating proportional reasoning and quantity relationships. Spatial reasoning is evident in zigzag and triangular planting patterns with consistent one-meter spacing, reflecting geometric structuring and spatial optimization. Farmers also apply estimation and numerical calculations to predict yields, measure planting depth, and determine economic value using both local units and kilograms. These practices align with key mathematical literacy domains, including quantity, space and shape, and uncertainty. This study contributes to ethnomathematics by demonstrating how cultural agricultural practices embody structured mathematical reasoning and provides a culturally relevant foundation for developing contextual and culturally responsive mathematics learning.

Students Perspective on How to Construct Local Cultural-Based Ethnomathematics Problem Solving
type: item
description: Current mathematics learning shows that problem solving often remain procedural and are not closely connected to local cultural contexts. Students generally tend to seek answers directly without going through systematic stages of problem understanding and strategy planning. The purpose of this study is to analyze the problem-solving ability of a question in the social and cultural context of local wisdom in Bojonegoro Regency. The current study was qualitative descriptive through problem-solving tests and interviews in collecting the data. The test results are then analyzed and described in relation to their problem-solving ability following Polya's steps. The respondents of this study were 6th-semester students in which they were selected using a purposive sampling technique. Two subjects were selected, namely ST (subjects chategorized with high ability) and SR (subjects with low ability). The results of the study showed that the two subject had different ways in solving the problems in a question, where ST has structured ways in solving problems compared to SR who using Polya's steps. Another finding was that students found non-mathematical information beyond the mathematical information related to the problem. This non-mathematical information refers to the stories related to local cultural wisdom that inherent in the problem. It makes learning more meaningful and provides the students with new experiences. Contextual learning that incorporated ethnomathematics elements that acts as a bridge for the students in understanding interconnection among mathematics and their daily lives.

Integrating SQ3R Strategies to Improve Mathematical Problem-Solving Capabilities in Material Triangles
type: item
description: Indonesian students often struggle with solving math problems, especially when it comes to geometry, like problems involving triangles. However, previous studies have mostly focused on SQ3R in reading comprehension or general mathematics learning, leaving a gap in its application to geometry-based problem-solving. This study aims to examine the effectiveness of integrating the SQ3R strategy to enhance students’ mathematical problem-solving abilities on triangle materials. The research used a quantitative-qualitative method with a quasi-experimental design, and included two groups: an experimental group and a control group. The students were from a seventh-grade class at SMP Negeri 4 Cimahi, and they were divided into the two groups based on purposeful selection. Data was gathered through problem-solving tests, classroom observations, and other records. The results showed that the group that used SQ3R improved much more in their problem-solving skills compared to the group that didn’t use it. The SQ3R method helped students break down problems, come up with plans, do calculations, and check their answers in a better way. This study highlights the need for active literacy-based strategies in mathematics instruction and suggests future research to explore the broader application of SQ3R in other mathematical topics and grade levels.

Designing a STEM-Based Learning Trajectory on Tangent Lines to Parabolas Using a Football Context for Pre-Service Teachers
type: item
description: Understanding the concept of a tangent line to a parabola is an important topic but often a challenge for prospective mathematics teacher students when learning emphasizes procedures over conceptual understanding. This research aims to design a STEM-based learning trajectory (Hypothetical Learning Trajectory) to enhance students' mathematical flexibility skills. The research method uses design research with three stages: initial design, learning experiment (pilot and full implementation), and retrospective analysis. The research subjects consisted of pre service mathematics teacher students from two classes. The learning path includes three STEM activities: exploring the crossbar challenge video in soccer, algebraic analysis and visualization using Desmos, and constructing and verifying tangents analytically and graphically. Data were obtained through classroom observation, interviews, worksheets, and videos, and were analyzed qualitatively using triangulation and the constant comparison method. The results show that students move from intuitive reasoning toward formal understanding thru transitions in contextual, symbolic, and graphical representations. Revising the HLT results in a Local Instructional Theory (LIT) that strengthens students' thinking flexibility and conceptual understanding. The results suggest that subsequent studies could refine and implement this LIT across diverse mathematical topics or STEM-integrated learning environments to examine its broader impact on students’ representational and reasoning flexibility.

E-Module Case Based Learning Assisted by Hypermedia For Support Literacy Statistics
type: item
description: Low levels of statistical literacy, as indicated by an average statistical literacy score of 40.6% among prospective teachers, are caused by a lack of connection between the theory taught in class and its application in real life. The integration of Case-Based Learning (CBL) with hypermedia can create an interactive and contextual learning environment, thereby enabling the development of statistical literacy. The objectives of this study include describing the development process, assessing the feasibility, and evaluating the effectiveness of hypermedia-assisted CBL e-modules in supporting statistical literacy. This study uses the Research and Development (R&D) method with reference to the Lee and Owens model. The research subjects consisted of three subject matter experts, three media experts, and 30 students from the Chemistry Education Study Program at a state university in Banten Province. Data were collected through interviews, questionnaires, and statistical literacy tests. Data analysis was performed using descriptive and inferential statistics. The development process went through the stages of needs analysis, design, development, implementation, and evaluation. The results showed that the hypermedia-assisted CBL-based e-module was feasible, practical, and effective in improving students' statistical literacy. This is evidenced by expert validation results showing a feasible category (78.5%), positive student responses (79%), and a significant increase in statistical literacy scores after using the e-module.

Researching on the Knowledge of Teachers Who Teach Math for Secondary Level Student Understanding
type: item
description: Although mathematics teachers' expertise in understanding subject matter is widely believed to have a direct impact on students' comprehension and academic achievements, there remains limited empirical research that specifically examines how teachers' content knowledge contributes to student learning outcomes. This study aims to assess the importance of mathematics teachers' competence in the content knowledge required for teaching secondary school mathematics. The research involved 55 secondary mathematics teachers who specialize in SS-level subjects for grades 10–12. Participants were selected through a combination of purposive and convenience sampling, considering their subject expertise and availability. Data were collected using a validated 25-question mathematics subject knowledge test, administered over 60 minutes via EduSuite computer-assisted instruction (CAI) software. The test was designed to evaluate teachers' understanding of essential mathematics topics taught in schools. Data analysis involved descriptive statistics, frequency distributions, and one-way ANOVA to assess the variation in mathematics knowledge and classify achievement levels based on established benchmarks. The findings provide a comprehensive overview of teachers' proficiency in key areas, including algebraic patterns, functions and relationships, space, geometric shapes, measurement, operations, trigonometry, and geometry. These results underscore the significance of strengthening mathematics content knowledge as part of teacher professional development. This study provides a solid foundation for designing targeted training and education programs aimed at improving the quality of mathematics instruction at the secondary level.

Mathematical Problem-Solving Ability from the Perspective of the Computational Thinking Approach
type: item
description: Computational thinking is a practical approach to solving mathematical problems that encourages students to think critically, creatively, and systematically. This type of research employs a descriptive, qualitative approach that aims to describe the mathematical problem-solving abilities of grade 9 students from private junior high schools in Malang, with a focus on computational thinking. The subjects of the study consisted of 6 students representing two high categories, two medium categories, and two low categories, based on the results of the mathematics exam. Data collection techniques include documents, such as student learning scores and tests to measure students' computational thinking abilities, as well as interviews to refine the test results. The data were then analysed based on computational thinking indicators, including decomposition, pattern recognition, generalisation, abstraction, and algorithmic thinking. In the final stage, a description of computational thinking-based problem-solving abilities is presented. The results showed that students in the high category met four of the five computational thinking indicators, except for the generalisation indicator. Students in the medium category met all indicators, while students in the low category only met two indicators: pattern recognition and abstraction. This study emphasises the importance of computational thinking in mathematics education, which aims to improve students' problem-solving skills.

The Effect of Students' Self-Efficacy on Students' Mathematical Communication Skills in Elementary School
type: item
description: The low mathematical ability of students is a major challenge that needs to be addressed in elementary school mathematics education. The goal of this study is to assess the impact of students' self-efficacy on their mathematical communication skills. The method in this study uses a quantitative approach with comparative causal types using correlation and regression analysis. The population in this study is fifth-grade students in Bandung, and the sample used is 84 fifth-grade students from one of the elementary schools in Bandung. The instruments used in this study were students' mathematical communication skills test questions, totaling 4 questions with the type of story questions on comparative material, and non-test instruments in the form of questionnaires related to students' self-efficacy. Data analysis in this study used SPSS 24 software to analyse the correlation and regression of students' self-efficacy and their mathematical communication skills. Additionally, a qualitative descriptive analysis was conducted on the students' responses regarding their mathematical communication skills. The research results indicate that, 1) there is a positive correlation between students' self-efficacy and their mathematical communication abilities with the correlation coefficient R = 0.219, which means that 4.8% of students' mathematical communication skills are determined by self-efficacy factors, 2) Students' self-efficacy has a positive effect on their mathematical communication skills with the regression equation y = 57.8 + 0.6x, which means that every time self-efficacy scores increase by 10 units, students' mathematical communication skills scores increase by 6 units. This research serves as a basis in the effort to create effective and meaningful mathematics learning by considering mathematical communication and students' self-efficacy.
