Abstract

This study aims to analyze the relationship between self-efficacy and high school students' errors in functional thinking using Newman Error Analysis (NEA). This study uses a qualitative approach with a descriptive method to analyze the pattern of students' functional thinking errors in solving mathematical problems. The subjects of the study were selected by purposive sampling based on variations in students' self-efficacy levels (high, medium, and low) to obtain a more comprehensive representation in the analysis of functional thinking errors. Students' self-efficacy was measured using a Likert scale-based questionnaire, while essay-based tests were used to identify their mathematical functional thinking abilities. Additional data were obtained through interviews based on interview guidelines to understand students' functional thinking processes in solving problems. The validity of the research data was achieved using the triangulation method by comparing test result data, questionnaires and interview guidelines. The results showed that students with high and medium self-efficacy tended to make fewer functional thinking errors than students with low self-efficacy. Students with low self-efficacy made more errors in understanding problems (comprehension errors), transforming information (transformation errors), applying procedures (process skill errors), and writing final answers (encoding errors). These findings can be a basis for teachers in designing more effective learning strategies to improve understanding of the concept of function.

Abstract

The student's ability to express and understand mathematical ideas in writing; Whether in tables, formulas, diagrams, drawings, or demonstrations, is called the student's written mathematical communication skills. Van Hiele's theory divides students' development in learning geometry into five levels, namely from level 0 to level 4. The purpose of this study is to find out students' mathematics ability in written communication based on Van Hiele's theory which is reviewed from gender differences. This research is a qualitative descriptive research. Students' mathematical communication skills at level 4: (1) can visually classify flat shapes, (2) can describe flat shapes visually, (3) can show the characteristics of flat shapes through pictures, (4) can write the relationships of concepts on flat shapes well, (5) can write how to determine the area and circumference of flat shapes, (6) can use terms and notation to present data. Meanwhile, level 1 students are still not able to describe the shapes of flat buildings visually well and are not able to write down the relationship of concepts on flat buildings well. In addition, related to gender, some aspects are superior to men and others are superior to women.

Abstract

This research investigates the efficacy of combining Augmented Reality (AR) technology with the Realistic Mathematics Education (RME) methodology in developing students' mathematical problem-solving capabilities. The investigation examines how the AR-RME integration functions as a potential educational innovation for boosting learner involvement and conceptual comprehension. This research employs a combined design incorporating numerical and descriptive-analytical frameworks. A cohort of 17 secondary school adolescents engaged in AR-RME-facilitated learning across five instructional sessions. Evaluation of participants' problem-solving proficiency was conducted through comparative pre-intervention and post-intervention assessments based on Polya's four-stage methodology: issue identification, procedural planning, implementation of strategies, and outcomes evaluation. Systematic observations were conducted to evaluate student engagement levels. The results of the observations showed the enthusiasm and active participation of the students during the learning. Statistical analysis using paired t-tests revealed a significant improvement in problem-solving skills (t = 8.742, p < 0.05), with the average score increasing to 74.81%. These findings show that AR-RME effectively improves spatial reasoning and understanding of three-dimensional geometry concepts, especially on cubes and blocks. This study confirms that AR-RME is an innovative approach that enhances problem-solving skills and becomes a more interactive and effective learning alternative to conventional methods.

Abstract

This study aims to examine: (1) differences in Calculus learning achievement between students using mobile learning with differentiated instruction (DI) and those using modules, (2) differences in achievement based on students' learning styles, and (3) the interaction between instructional methods and learning styles on learning outcomes. The participants were 112 Informatics Engineering students at Universitas Darussalam Gontor in the 2023/2024 academic year, divided into two groups: 59 students in the experimental group (using mobile learning) and 53 in the control group (using modules). The study was conducted over five sessions on the topic of Absolute Value Equations and Inequalities. A quasi-experimental method with a 2x3 factorial design was used. The research instruments included an achievement test and a learning style questionnaire. Data were analyzed using two-way ANOVA after confirming normality and homogeneity assumptions. The results showed that: (1) mobile learning with DI is more effective than modules, (2) learning styles significantly affect learning achievement, and (3) there is no interaction between instructional method and learning style. These findings suggest that mobile learning with DI can be effectively implemented regardless of students' learning styles and supports the development of inclusive digital learning environments in higher education.

Abstract

Introduction to Group Theory is one of the courses in the field of algebra studies in Mathematics Education Study Program at Universitas Negeri Semarang. Various learning models are implemented in lectures to overcome students' difficulties in understanding and mastering abstract lecture material. In this research, learning was carried out using the DNTK Pattern approach. The DNTK pattern approach is a learning pattern that prioritizes understanding Definitions (D) and their Negations (N), Theorems (T) and their Contrapositions (K) before students are given exercises in the Introduction to Group Theory course. The main goal of this approach is to increase students' conceptual understanding of the structure and properties of groups. This research used quantitative methods and the TAM (Technology Acceptance Model) approach to evaluate the effectiveness of the DNTK pattern approach in improving student learning outcomes. The research results showed that students taught using the DNTK pattern approach have a deeper understanding and are able to apply concepts better compared to conventional learning. This article reviewed the DNTK pattern approach theoretically and empirically, and presented the research results as a basis for further implementation in Introduction to Group Theory lectures.

Abstract

Algebraic reasoning is a fundamental competency in mathematics learning; however, many students experience difficulties in applying algebraic concepts, particularly in quadratic functions. This study aims to enhance students’ algebraic reasoning through the implementation of the SSCS (Search, Solve, Create, and Share) strategy, a structured problem-solving instructional approach that emphasizes systematic exploration, solution development, model construction, and mathematical communication. The study employed a collaborative classroom action research design involving Grade X senior high school students, conducted across two cycles consisting of planning, action, observation, and reflection stages. Students’ algebraic reasoning was assessed using indicators that include pattern recognition, algebraic representation, manipulation of algebraic expressions, and logical justification. Data were collected through algebraic reasoning tests and classroom observation sheets. The findings reveal a substantial improvement in students’ algebraic reasoning abilities, with the mean score increasing from 62.33 in the pre-cycle to 81.25 in Cycle II. Additionally, the percentage of students achieving mastery learning increased from 27.78% to 91.67%. These results indicate that the SSCS strategy effectively supports the development of algebraic reasoning by engaging students in structured problem-solving and reflective mathematical communication.

Abstract

Growth mindset is known as a believe that intelligent can be learned. Learning anxiety might occur due to self-doubt that one has an ability to learn, such as in a complex topic in mathematics. Therefore, it is assumed that a positive affirmation that directs growth-mindset might be used to manage anxieties in learning mathematics. This study was aimed to investigate that beside the worked example might increase extraneous cognitive load for more knowledgeable learners, it might also be possible it affects anxiety. A total of 128 Indonesian junior high school students were randomly placed in four experiment groups by using the 2x2 factorial design (with vs. without growth mindset affirmation) x (worked example vs. problem solving based instruction) to examine the instruction on transfer abilities, cognitive loads, and level of anxieties. Using ANOVA(s), findings support the expertise reversal effect that the worked examples were disadvantageous for more knowledgeable learners. The data reveals that they also experienced significantly higher anxiety during learning compared to the counterparts. Nevertheless, no effects were found in favor of the growth mindset affirmation.
