Abstract

Education plays an important role in developing students’ potential, especially critical and creative thinking. Mathematics, as a core subject, supports students’ problem-solving ability, which involves understanding, procedure selection, and application in new contexts. One factor that may influence this ability is self-confidence, as confident students are more persistent and independent in solving problems. This study aimed to examine the effect of self-confidence on students’ mathematical problem-solving ability. The research employed a quantitative correlational design with a purposive sample of 60 seventh-grade students at SMP Negeri 8 Kota Gorontalo. Instruments consisted of a mathematical problem-solving test and a self-confidence questionnaire. Data were collected through tests and questionnaires, then analyzed using simple linear regression and correlation coefficient tests. The findings revealed that self-confidence significantly affects students’ mathematical problem-solving ability. Students with higher self-confidence tended to achieve better outcomes. The correlation coefficient was 0.6923 (strong positive), with a coefficient of determination (R²) of 47.22%, indicating that self-confidence contributed nearly half of the variation in problem-solving ability. The remaining 52.78% was influenced by other factors not examined in this study, such as math anxiety, learning habits, and environmental support. In conclusion, self-confidence has a positive and significant effect on mathematical problem-solving ability, suggesting the importance of fostering students’ confidence alongside academic skills.

Abstract

The inability of primary school students to solve mathematical problems using multiple strategies, often rigidly adhering only to methods taught by the teacher, highlights a critical issue: a low level of Divergent Thinking. This study aims to investigate the effectiveness of the Problem-Based Learning (PBL) model utilizing Dienes Blocks in enhancing the Divergent Thinking skills of fourth-grade students in whole number operations. The research employed a quantitative One-Group Pretest-Posttest Design involving a sample of 30 students from a public elementary school in Cimahi City. The intervention was conducted over two meetings, focusing on guiding students through the PBL process to discover and articulate various methods for solving calculation problems. Data were collected using a six-item essay test designed to measure the students' fluency and flexibility in problem-solving strategies, a core indicator of Divergent Thinking. The findings indicate a significant improvement in students' Divergent Thinking ability after the implementation of the PBL model with Dienes Blocks. The increase in scores, analyzed using the N-Gain method, was categorized as moderate. This suggests that the combination of authentic problem contexts provided by PBL and the concrete manipulation offered by Dienes Blocks effectively enables students to break free from rote memorization and explore alternative problem-solving pathways. The study concludes that this integrated approach is an effective strategy for fostering cognitive flexibility and creativity in elementary mathematics education.

Abstract

Critical thinking is an essential component of mathematics learning, particularly when students are required to solve word problems that demand reasoning, interpretation, and systematic decision-making. However, evidence from previous studies shows that many junior high school students still struggle to apply critical thinking skills effectively, especially in the topic of Systems of Linear Equations in Two Variables (SPLDV). This study aims to analyze the types of errors made by students when solving SPLDV word problems based on indicators of mathematical critical thinking skills. This qualitative descriptive study involved 36 eighth-grade students from SMP Negeri 1 Ciranjang. The data were collected through five open-ended test items developed according to four indicators of mathematical critical thinking: interpretation, analysis, evaluation, and inference. Students’ written responses were scored using an established rubric, and the data were analyzed through the processes of data reduction, data presentation, and conclusion drawing. The findings show that students frequently experienced several types of difficulties, including: (1) failing to identify the known and asked information; (2) using unsystematic problem-solving procedures; (3) constructing incorrect or incomplete mathematical models; (4) applying inappropriate strategies; (5) performing inaccurate or incomplete calculations; and (6) being unable to draw conclusions aligned with the context of the problem. These results indicate that students’ mathematical critical thinking skills related to SPLDV remain weak and require improvement. Therefore, structured guidance, explicit reasoning instruction, and consistent practice are needed to strengthen students’ problem solving abilities.

Meanwhile, self regulated learning skills is aims to increase their sense of responsibility for their own learning. This research aims to improve both of these abilities through the geogebra assisted the problem-based learning, so the students can be better understand about concepts that taught by the teacher, take responsibility, and build their self regulated learning. The researcher used a quasi-experimental design with a pretest-posttest approach involving both experiment and control groups, that each consisting of 25 student in eighth-grade from SMP EL Fitra Bandung. The first step that reseacher take is given a pretest to both of class, after that continue to give experiment class with geogebra assisted the problem based learning method and control class with a conventional method. The research instruments used were a mathematical reasoning essay test about system linear equation in two variabels (SPLDV) and a self regulated scale. The integration of geogebra software is in line with current technological advancements and make the student more interesting when learning many subject at school specially in mathematic program. The results showed that students who received geogebra assisted problem-based learning method performed better in reasoning ability compared to those who received conventional method. However, there was no significant difference in self regulated learning between the two groups, indicating that both the experimental and control groups experienced an increase in self regulated learning.

Abstract

Misconceptions are common among students when solving mathematics problems and, if left unaddressed, may hinder their ability to understand the material. This study seeks to design and develop diagnostic test instruments—comprising questions and questionnaires—on algebra topics using the Appsheet application. The objectives are to assess the development process, feasibility, and effectiveness of the instruments, as well as to identify challenges faced during implementation. The research employed a Design Research approach with a development studies type, consisting of two stages: preliminary design and formative evaluation. The instruments underwent a one-to-one trial with three students, a small-group trial with six students, and a field test involving 33 eighth-grade students at SMP Negeri 1 Margaasih. Expert validation rated the instruments as “feasible.” Data were gathered through documentation, tests, and interviews. The instruments included 10 three-tier multiple-choice questions, a closed-ended questionnaire with 13 items, and interviews with both teachers and students. Analysis revealed that 3.9% of students understood the concepts, 8.2% exhibited positive misconceptions, 8.4% negative misconceptions, 22.1% general misconceptions, while 57.3% showed no conceptual understanding. These findings demonstrate that the instruments effectively identified algebraic misconceptions. Challenges encountered included limited school facilities for mobile device usage and occasional errors in the application when accessed simultaneously by many users, indicating the need for updates. Nevertheless, the Appsheet-assisted three-tier diagnostic test provides a feasible and promising tool for detecting misconceptions in junior high school algebra learning

Abstract

Algebraic thinking skills play an important role in mastering mathematical concepts and problem-solving; however, Linear Algebra learning still faces difficulties, particularly in understanding proofs. Therefore, a proof-based Guided Inquiry strategy is needed to help students develop deeper algebraic thinking skills. This study aims to describe the implementation of the proof-based Guided Inquiry strategy, analyze the improvement and achievement of students’ algebraic thinking skills between classes using this strategy and those using conventional learning, and describe students’ responses to Linear Algebra learning through this approach. The research employed a mixed-method approach with a quasi-experimental design using a non-equivalent control group. The subjects were two classes of mathematics education students, each acting as an experimental and control class. The instruments consisted of pre- and post-tests of algebraic thinking skills, implementation observation sheets, and student response questionnaires. Quantitative data were analyzed using N-Gain and mean difference tests, while qualitative data were obtained from observations and student responses. The results showed that the implementation of learning achieved an average score of 92% (very good category). N-Gain analysis revealed that the experimental class achieved a moderate improvement (0.401), higher than the control class (0.246, low category). Moreover, student responses were positive, with an average percentage of 84.8%. These findings indicate that integrating inquiry exploration with mathematical proof effectively enhances students’ algebraic thinking skills and the quality of Linear Algebra learning.

Abstract

The mathematical problem-solving ability of junior high school students is still considered low, as evidenced by the low learning outcomes among seventh-grade students at SMP Negeri 1 Suwawa. To enhance this ability, an innovative learning model is required. One such model is ICARE, which is believed to encourage active student engagement and foster a deeper understanding of mathematical concepts. This study aims to determine the differences between the ICARE learning model and the conventional learning model on the mathematical problem-solving abilities of seventh-grade students at SMP Negeri 1 Suwawa. The research was conducted from May to June during the even semester of the 2024/2025 academic year. The research method employed in this study was an experimental method involving two classes, namely the experimental class and the control class. Simple random sampling was used to select the samples. The research design utilized was a Post-test Only Control Group Design. The data were collected through a written post-test. The results of the study, based on hypothesis testing using a t-test, showed that the obtained tcount​ = 3.050, while the critical ttable = 2.007 at a significance level of 0.05. Since tcount​> ttable the null hypothesis (H₀) was rejected and the alternative hypothesis (H₁) was accepted. Therefore, it can be concluded that the mathematical problem-solving ability of students taught using the ICARE learning model is higher than that of students taught using the conventional learning model.

Abstract

Statistical thinking is an essential competency for prospective mathematics teachers in responding to data-driven decision making within the context of Society 5.0. However, learning obstacles frequently emerge in higher education statistics courses due to instructional practices that emphasize procedural computation rather than conceptual and contextual understanding. This study aims to describe the implementation of a didactical design to reduce students’ learning obstacles in statistical thinking through the topic of measures of central tendency. A qualitative descriptive method was employed involving 38 mathematics education students enrolled in an introductory statistics course. The didactical design integrated the Theory of Didactical Situations (TDS) and the DORA model (Describe, Organize, Represent, Analyze–Interpret) and was delivered through an interactive e-module developed on the AnyFlip platform. Data were collected using a post-implementation statistical thinking test based on DORA, classroom observations, semi-structured interviews, and reflective field notes. Learning activities were organized into four TDS stages action, formulation, validation, and institutionalization to support reflective and adidactical learning processes. The results indicate that students were able to construct statistical concepts more meaningfully and reduce previously identified learning obstacles, particularly in linking numerical results with graphical representations. In conclusion, the integration of TDS and the DORA model supported by interactive e-modules effectively enhances students’ statistical thinking skills, as evidenced by the reduction of learning obstacles among prospective mathematics teachers.
