Abstract

This study was executed with the primary objective of thoroughly investigating the application and confirmed efficacy of the Numbered Head Together (NHT) Cooperative Model.The central focus of this research was its implementation within the context of Mathematics Instruction for fifth-grade students in elementary schools. The design and execution of this model specifically targeted three crucial pedagogical dimensions: promoting enhanced collaborative activity among students, cultivating a stronger sense of individual accountability, and solidifying students' conceptual understanding of the subject matter. Technically, the NHT procedure involved several core sequential stages:1)Numbering:Assigning a distinct identification number to each student within their respective teams.2) Discussion:Posing a question that necessitates a compulsory group discussion to collectively find a solution.3)Idea Consolidation: The moment when team members synchronize their thoughts and arrive at a consensus for the final answer.4) Random Call:The instructor randomly selects a number to designate which student will represent the group's response—a mechanism proven to effectively ensure the preparedness of every team member.Furthermore, the model demonstrated an ability to increase student participation across the board and, critically, resulted in a significant improvement in their Mathematics learning achievements, particularly concerning problem-solving competency.Based on these compelling results, it is concluded that the NHT Cooperative Model is exceptionally relevant and highly effective as a strategic instructional choice for Mathematics education at the primary school level. Consequently, it is strongly recommended that educators consider and adopt NHT as a viable pedagogical alternative for designing learning activities that actively demand both participatory engagement and robust teamwork from their students.

Abstract

This study aims to determine the effectiveness of the Problem Based Learning (PBL) model integrated with contextual teaching in improving students’ conceptual understanding of the states of matter and their changes in Grade IV at UPTD SDN 47 Gedong Tataan. This research employed a quasi-experimental method with a One Group Pretest–Posttest design involving 20 students. Data were collected using learning outcome tests and analyzed through the Shapiro–Wilk normality test and paired sample t-test. The results showed that the data were normally distributed (Sig. 0.658 > 0.05) and that there was a significant difference between pretest and posttest scores (Sig. 0.000 < 0.05). The mean score increased from 62.50 to 82.00, with an effect size of 2.20, categorized as very large. Therefore, the integrated PBL and contextual approach is effective in improving science learning outcomes on the topic of states of matter.

Abstract

This study examines the effects of learning interest (X1) and learning motivation (X2) on students’ mathematical understanding ability (Y) among Grade 10 students at SMA Negeri 1 Dolok Batu Nanggar in the 2024/2025 academic year. A quantitative approach was employed with a sample of 52 students selected through proportional random sampling. Data on interest and motivation were collected using questionnaires, while mathematical understanding was measured using an essay-type test. Data were analyzed using multiple linear regression with SPSS 21, preceded by assumption testing. The Kolmogorov–Smirnov test indicated that all variables were normally distributed (interest Sig. = .207; motivation Sig. = .517; understanding Sig. = .358; all > .05). Regression results showed that interest had a positive and significant effect on mathematical understanding (β = .799, t = 9.397, p < .001), and motivation also had a positive and significant effect (β = .601, t = 5.320, p < .001). Simultaneously, interest and motivation significantly predicted mathematical understanding (F = 60.156, p < .001) with R² = .711, indicating that 71.1% of the variance in mathematical understanding was explained by the two predictors. In the multiple regression model, interest was the more dominant predictor compared to motivation (βinterest = .663 > βmotivation = .301). These findings highlight the importance of strengthening students’ learning interest and motivation to improve mathematical understanding.

Abstract

This study aims to describe and analyze the cognitive errors of second-semester students in solving geometry problems based on ethnomathematics through the representation of Indonesian traditional houses. This research employed a descriptive qualitative approach involving 20 students as respondents. Data were collected through a questionnaire consisting of five descriptive geometry problems designed within an ethnomathematics context and documented via Google Drive. The data, in the form of students’ written responses, were analyzed by identifying errors in each problem. The results indicate that students made errors in identifying geometric shapes, understanding and interpreting problem statements, reading information accurately, performing rounding procedures, and distinguishing between plane and solid figures. From all respondents, five students were selected for in-depth analysis based on the variation of errors. The findings show that these errors are not only procedural but also related to conceptual understanding and visual interpretation. Therefore, more contextual learning with an emphasis on conceptual understanding is needed to minimize students’ cognitive errors.

Abstract

Understanding the concept of angles is an essential part of learning geometry; however, it remains a common difficulty for students. This study aims to analyze students’ understanding of angle concepts in mathematics learning at UPT SMP Negeri 14 Medan. This research employed a descriptive quantitative approach, with data collected through observation and written tests. The sample consisted of 27 seventh-grade students selected using purposive sampling. Students’ understanding was analyzed based on four aspects: basic conceptual understanding, representation ability, computational ability, and application ability. The results showed that basic conceptual understanding was in the good category (81%), representation ability was in the low category (37%), computational ability was in the moderate category (67%), and application ability was also in the moderate category (70%). These findings indicate that students have a good understanding of basic concepts; however, they still experience difficulties in representing and applying these concepts optimally. Therefore, it is necessary to implement learning strategies that emphasize the development of representation skills and problem-solving abilities in order to enhance students’ understanding of angle concepts in a more comprehensive and meaningful way.

Abstract

Euclidean geometry is a branch of mathematics that examines the properties of plane and spatial figures based on axioms and deductive reasoning. Therefore, understanding the concept of triangles is an important foundation for developing spatial abilities and problem-solving. Euclidean geometry examines the properties of plane and spatial figures through axioms and logical reasoning. Understanding the concept of triangles is crucial for spatial abilities and problem-solving. However, students still tend to memorize formulas without understanding their real-life applications. Therefore, culturally based questions such as traditional houses, ulos cloth, and traditional activities are used to assess conceptual understanding.This study applied a qualitative descriptive method involving 20 Mathematics Education students. Data were collected through an online ethnomathematics-based questionnaire and analyzed using Newman’s error analysis stages. The results showed that the highest errors occurred in understanding questions and writing final answers. Students also had difficulties transforming contextual problems into mathematical models. These findings indicate that the ethnomathematics approach provides more meaningful learning contexts, but students’ conceptual understanding still needs improvement through learning strategies that emphasize reasoning and mathematical communication.

Abstract

This study aims to analyze students' geometric reasoning in solving triangle problems in Euclid Geometry through the representation of Ulos Batak motifs and identify the types of errors that occur. This study uses a descriptive qualitative approach with the subjects of 15 students in the fourth semester of Mathematics Education. The instrument was in the form of 5 HOTS-based description questions, and the data were analyzed using the Miles and Huberman model and Newman Error Analysis (NEA). The results showed that students' geometric reasoning skills were in the high category, with 80% in the high category and 20% in the medium category, and an average score of 87.4%. The aspects of understanding and transformation are relatively good, while reasoning and connection are still low. The dominant error is interpretation error. Thus, the use of Ulos Batak motifs supports geometry learning, but it needs to be strengthened in the aspects of interpretation and concept connection.

Abstract

This study aims to analyze the problem-solving abilities of second-semester students of Mathematics Education at Universitas Negeri Medan on triangle plane geometry material contextualized with the local wisdom of North Sumatra, using Newman's Error Analysis (NEA) framework. A descriptive quantitative method supported by qualitative analysis was employed. The research subjects consisted of 30 students selected through purposive sampling. The data collection instrument comprised five essay questions based on ethnomathematics, incorporating contexts such as Gorga Batak ornaments, Rumah Bolon architecture, Honai, and ulos motifs. Data analysis was conducted by categorizing student errors into five Newman stages: Reading, Comprehension, Transformation, Process Skills, and Encoding, with descriptive percentage calculations. The results indicate that the highest error rate occurred at the Transformation stage (42.3%), followed by Process Skills (35.7%), Comprehension (10.8%), Encoding (6.0%), and Reading (5.2%). These findings suggest that students face significant barriers in horizontal mathematization—namely, the ability to convert contextual situations into formal mathematical models. Local wisdom contexts were found to enhance student engagement in the early stages of problem-solving but were insufficient to promote formal deductive reasoning. This study recommends the development of more structured ethnomathematics-based teaching materials oriented toward formal mathematical thinking processes.

Abstract

This study aims to analyze students’ solutions to plane geometry problems on triangle topics presented in a local cultural context in mathematics learning. The research employed a qualitative descriptive approach involving 25 second-semester students of the Mathematics Education Study Program at Universitas Negeri Medan. The research instrument consisted of five essay-type geometry problems based on local cultural contexts designed to encourage higher-order thinking skills. Data were analyzed using Newman’s Error Analysis, which includes reading, comprehension, transformation, process skills, and encoding stages. The findings indicate that the highest percentage of errors occurred at the process skill stage (15%), followed by transformation errors (13.3%). Comprehension and encoding errors each accounted for 11.6%, while no reading errors were identified. These results suggest that students still face difficulties in applying mathematical procedures and translating contextual problems into appropriate mathematical models.
