Abstract

This study aims to describe the concept understanding ability of students on SPLDV material in terms of extroverted and introverted personalities at SMPN 7 Palu. The type of qualitative research is descriptive. The subjects of this study were students of class VIII D SMPN 7 Palu consisting of 20 students. However, in this study the subjects that researchers used were one student with introverted personality and one student with extroverted personality. Data collection techniques used personality questionnaires, written tests and interviews. The results of this study indicate that (1) Introverted students restate a concept by restating equation 1 and equation 2 obtained from the problem into another form, namely the SPLDV form correctly and tend to imitate what is in the problem without using their own language. Meanwhile, extroverted students restate a concept by restating the equations obtained from the problem into another form, namely the SPLDV form in their own language, not influenced by information from the problem and more likely to use their own language. (2) Introverted students provide examples of SPLDV and those that are not SPLDV based on examples of SPLDV obtained from the problem. While extroverted students provide examples that include SPLDV by looking at the SPLDV example that SE gets in the problem, but SE is unable to provide examples that do not include SPLDV because there are no examples, this means that SE can provide examples if you see an existing example. (3) Introverted students present concepts in various forms of mathematical representation in a structured manner, the steps are clear by writing in full what is known from the problem and then presenting it in the form of a mathematical model. Meanwhile, extroverted students present concepts in various forms of mathematical representation on the system of linear equations of two variables by directly presenting it in the form of a mathematical model without clear and unstructured steps by not writing what is known from the problem and directly presenting it in the form of a mathematical model. (4) Introverted students can develop necessary or sufficient conditions for a concept by writing and developing the exact conditions of one SPLDV solution and being able to determine the value of a correctly along with a clear and complete solution. Meanwhile, extroverted students develop the necessary or sufficient condition of a concept and determine the value of a by answering carelessly without doing the solution. (5) Introverted students use, utilize and select certain procedures or operations and apply concepts by determining what methods should be used in solving SPLDV problems in a structured manner, the steps are clear and the final results obtained are correct. While extroverted student subjects use, utilize, and select certain procedures or operations and apply concepts to SPLDV material with incorrect final results.

Abstract

This study investigated the effect of numeracy skills on mathematics learning outcomes, specifically in the area of 2 plane figures, among 61 fifth-grade students in Labuan Regency. Using a quantitative correlational design, descriptive results showed that students' numeracy skills were in the good category (average 75.90) and learning outcomes were in the fair category (average 70.33). The Spearman rank correlation test showed a positive and significant effect, but the relationship was weak (r = 0.292; p = 0.023 < 0.05). These findings confirm that better numeracy skills contribute to higher learning outcomes, but the weak correlation underscores the important role of other factors (e.g., teaching methods, motivation). This study implies that teachers should optimize contextual numeracy-based learning to improve achievement, especially for complex concepts such as the area of a trapezoid.

Abstract

This study aims to describe the errors of grade VIII students at SMP Negeri Satap 1 Tinombo Selatan in solving story problems involving two-variable linear equation systems using the Newman method. Newman’s method identifies five types of errors: reading, understanding, transformation, process skills, and coding. This research employs a descriptive qualitative approach. The subjects include three students with different mathematical abilities: one high-achieving student (A), one medium-achieving student (T), and one low-achieving student (S). Data collection techniques involve written tests and interviews, with data credibility ensured through member checking. The data analysis process includes data condensation, data presentation, and conclusion drawing. The results indicate that none of the subjects experienced reading errors. However, all three made mistakes in understanding the problems. Subject T did not write what was asked in problem one and misidentified the question in problem two. Subject S also failed to state what was asked in problem two. All subjects struggled with transformation errors, mainly due to incorrect variable assignments. Subjects A and S made errors in problem two, while subject T also struggled with proper notation. Regarding process skills, subject A could not complete the division operation, subject T failed in algebraic manipulation in problem one and miscalculated multiplication in problem two, and subject S did not proceed to the next step. Finally, all three subjects made coding errors. Subjects A and S did not write conclusions, while subject T omitted and incompletely stated conclusions for problem two.

Abstract

This study aims to analyze the errors of ninth-grade students at SMP Negeri 5 Palu in solving word problems involving arc length and sector area using the Newman procedure, from a cognitive perspective. The subjects in this study were 26 ninth-grade students in the 2024/2025 academic year. Subjects were recruited using the GEFT test. Data were analyzed using the Newman procedure to identify error types. Data collection techniques included the GEFT test, written tests, and interviews. The results showed that both FI and FD students made no errors in reading and understanding the problems. FI students were more thorough in the transformation and process skills stages, but experienced difficulties in the final writing due to time constraints. Meanwhile, FD students made errors in transformation and process skills, particularly in entering incorrect radius values ​​into formulas, as well as errors in the final writing. Cognitive style influenced the types of errors made by students. FI students were more able to solve problems independently, while FD students required more guidance.

Abstract

This study aimed to examine the effectiveness of the Problem-Based Learning (PBL) model assisted by GeoGebra on students’ mathematical literacy skills in solid geometry. The research employed a quantitative approach using a quasi-experimental design with a pretest-posttest control group design. The population consisted of ninth-grade students at a junior high school in Palu, and the sample was selected using cluster random sampling. Data were collected through essay tests to measure students’ mathematical literacy skills. Data analysis was conducted using the independent sample t-test and N-gain analysis at a significance level of 0.05. The results showed that the Sig. (2-tailed) value was 0.001, indicating a statistically significant difference between the experimental and control groups. The average N-gain score in the experimental class was 0.46, which falls into the moderate category and is higher than that of the control class, which was 0.15 in the low category. These findings indicate that the Problem-Based Learning (PBL) model assisted by GeoGebra is effective in improving students’ mathematical literacy skills in solid geometry and can be used as an alternative instructional approach in mathematics learning.

Abstract

Learning achievement in mathematics at the university level is influenced by various internal factors, including students’ beliefs in their abilities and their capacity to regulate learning processes. This study aims to examine the effects of self-efficacy and self-regulation, both individually and simultaneously, on university students’ mathematics learning achievement. An ex post facto quantitative design was employed involving 98 mathematics education students selected through proportional random sampling from a population of 130 students. Data were collected using self-efficacy and self-regulation questionnaires, as well as students’ grade point averages from first- and second-semester mathematics courses as indicators of learning achievement. The data were analyzed using simple and multiple linear regression after meeting classical assumption requirements. The results indicate that self-efficacy has a significant effect on mathematics learning achievement, contributing 15.5% of the variance, while self-regulation contributes 13.1%. When analyzed simultaneously, both variables significantly influence learning achievement with a combined contribution of 16.7%. Despite their statistical significance, the magnitude of these effects is relatively modest, suggesting that mathematics learning achievement is shaped by a combination of internal and external factors beyond self-efficacy and self-regulation alone. These findings imply that efforts to improve students’ mathematics achievement should not only focus on strengthening self-efficacy and self-regulation but also be supported by effective instructional strategies, learning environments, and institutional support. This study provides empirical evidence for mathematics educators to design learning interventions that integrate psychological and pedagogical approaches in higher education contexts.
