Abstract

Background: Students in higher education consistently demonstrate significant difficulties in integral calculus, particularly in selecting appropriate problem-solving strategies and executing procedural steps. Despite extensive research on mathematical errors, studies integrating Newman Error Analysis (NEA) with technology-enhanced, project-based pedagogy at the university level remain scarce. Objective: This research aims to examine the types of errors students make in solving integral problems in calculus by implementing Project-Based Learning (PBL) using GeoGebra software. Methods: The research adopted a descriptive qualitative method with 15 ACT students from the Informatics Department of Universitas Pelita Harapan Medan. Data were collected from written integral test items, observation sheets, and brief interviews with selected students. Errors made by students were classified according to the Newman Error Analysis (NEA) framework, which consists of reading, comprehension, transformation, process skill, and encoding errors. Results: The findings suggest that the combination of PBL with GeoGebra enables students to visualize integral concepts dynamically and enhances their geometric understanding of both definite and indefinite integrals. The most frequent error was transformation (60%), followed by process skill (53.3%), comprehension (46.7%), reading (20%), and encoding errors (13.3%). These results indicate that many students continue to struggle with deciding how to integrate an expression and completing the correct computations. The method helped alleviate conceptual difficulties owing to the visualization features of GeoGebra. Conclusion: GeoGebra-assisted PBL effectively supports error diagnosis and conceptual remediation in integral calculus. Integrating dynamic visualization with project-based inquiry reduces transformation and process skill errors by helping students connect symbolic procedures to geometric interpretations.

Abstract

This study analyzes students' numeracy literacy skills at the middle level (levels 3 and 4). The research subjects comprised three students from SDN (elementary school) 106831 Bakaran Batu, Deli Serdang Regency, representing varying initial math abilities (high, medium, and low). Student groupings were based on data from mathematics test scores. The research follows a descriptive qualitative approach using Sugiyono's methodology. The research instrument employed was a mid-level numeracy literacy ability test (level 3 and level 4), which included questions assessing cognitive processes related to application and reasoning, as well as interview guidelines. Data analysis techniques involved data reduction, presentation, and conclusion. The study revealed that highly skilled students demonstrated proficiency in level 3 (application) and level 4 (reasoning) numeracy literacy. However, students with moderate and low abilities struggled to understand questions at these levels. Common student errors included failing to record relevant information from the questions, making mistakes in problem-solving processes, and neglecting to document their answer conclusions. The main factor hindering students' ability to answer moderate-level numeracy literacy questions appears to be their lack of familiarity with word problems related to everyday life. Additionally, students have difficulty grasping the relationship between concepts presented in contextual problems.

Abstract

This study examines the background of problem-solving ability and creative attitudes among junior high school students, highlighting their importance in fostering innovation and critical thinking in mathematics education. The purpose of this study is to analyze the influence of problem-solving ability on students' creative attitudes. The classroom process is a learning process that develops local instructional theories for the material of systems of linear equations in two variables. The quantitative study aims to assess the influence of problem-solving ability on students' creative attitudes. This study involved 24 junior high school students in Medan as a sample. The instruments used were a validated problem-solving ability test and a validated creative attitude scale. The results showed that problem-solving ability has a significant positive effect on students' creative attitudes, with a regression coefficient of 0.951, indicating that greater problem-solving ability is associated with stronger creative attitudes. The coefficient of determination (R² = 0.597) indicates that 59.7% of the variation in students' creative attitudes is due to problem-solving ability. In contrast, friendship (40.3%) is due to other factors not examined in this study. These findings suggest that problem-solving ability is a key factor in developing creative attitudes. This study highlights the need to integrate problem-solving ability into the educational curriculum to foster students' creative attitudes. Future research should consider using a larger sample size.
