Abstract

The low interest of students in learning mathematics has an impact on learning outcomes which is one of the efforts in achieving learning goals. One effort that can be made to increase student interest in learning mathematics is to present more interesting materials and guide students to be more active. Thus, teachers are required to be creative and innovative in choosing learning media by adjusting student characteristics and combining media to support student learning interests. This study aims to determine the effect of interactive media on student learning interests. And to determine the completeness of student learning in mathematics material. The type of research used is pre-experimental design with a One-Group-Pretest-Posttest design research design. The sampling technique uses a saturated sampling technique which is all the population in class IV of SD Negeri Rumpet Aceh Besar as many as 24 students, consisting of 11 male students and 13 female students. Data were obtained using a learning interest questionnaire and test questions. Based on the results of the hypothesis test using the Paired Sample t-Test with a significance level of 0.05 (2-tailed), a significance of 0.00 was obtained. This shows that 0.00 < 0.05, then it can be concluded that there is an influence of the use of interactive animation media on the learning interest of students at Rumpet Aceh Besar Elementary School. This is also supported by the percentage of classical completion reaching 100% complete with a KKTP of 75%. Thus, interactive animation media has an effect on students' learning interest with learning outcomes achieving completion.

Abstract

This study explores the development and application of a praxiology-based instrument designed to identify and address learning obstacles in the teaching of the concept of proportion in early algebra. Proportion plays a crucial role in connecting concrete numerical concepts with abstract algebraic thinking; however, many students face significant challenges when transitioning from numerical to algebraic representations. The study utilizes a praxiology framework, which emphasizes the relationship between the type of mathematical task, the techniques employed by students, and the underlying theoretical principles that shape students' understanding. This framework provides a deeper understanding of how task design can influence students' mathematical practices, making it particularly effective for diagnosing learning obstacles in proportion-related tasks. The instrument, which was applied to seventh-grade students in Bandung, Indonesia, consists of five types of tasks aimed at developing students’ skills in arithmetic-algebraic representations and solving linear equations in both abstract and contextual forms. By predicting students' potential solutions and analyzing their problem-solving strategies, the study highlights how the praxiological approach facilitates the identification of key difficulties in students' understanding of proportion. The findings demonstrate that this approach not only helps to diagnose learning obstacles more effectively but also supports the creation of targeted instructional strategies that improve students’ grasp of proportional reasoning. This research contributes valuable insights into the use of praxiology in mathematics education, offering a robust framework for analyzing and overcoming learning obstacles in early algebra instruction.

Abstract

This study aims to develop a Student Worksheet based on the Project-Based Learning (PjBL) approach, ensuring its validity, practicality, and effectiveness in facilitating mathematics instruction on the topic of circumference and area of circles for MTs students. The research follows a Research and Development (R&D) methodology, employing the ADDIE development model, which encompasses five stages: Analysis, Design, Development, Implementation, and Evaluation. The validation process assessed the worksheet’s quality across four aspects: content feasibility, material presentation, worksheet structure, and linguistic quality. The results indicate that the content feasibility scored 84%, material presentation 86.5%, worksheet elements 86%, and linguistic quality 88%, all within the “very valid” category. Overall, the Student Worksheet achieved a validity score of 86% (categorized as “very valid”), confirming its appropriateness for use in the classroom. These findings suggest that the PjBL-based Student Worksheet effectively supports mathematics learning and meets expert criteria for validity.

Abstract

Mathematical conceptual understanding is a fundamental skill that serves as a foundation for more advanced abilities, including reasoning, communication, connections, and problem-solving. However, this foundational skill is influenced by students’ prior mathematical abilities. Therefore, the objective of this study is to identify and describe differences in students’ mathematical conceptual understanding based on their prior mathematical abilities. This research employs a mixed-method approach, involving 87 purposively selected students enrolled in the Analytic Geometry in Planes and Space course. The research instruments include a mathematical conceptual understanding test and documentation of students’ prior mathematical abilities. Data were analyzed quantitatively using one-way ANOVA and qualitatively by exploring mathematical conceptual understanding across categories of prior mathematical abilities. The findings reveal that both quantitative and qualitative analyses indicate that students with high prior mathematical abilities demonstrate superior mathematical conceptual understanding compared to those with medium or low prior mathematical abilities.

Abstract

This article´s objective is to present the current state of research on the teaching-learning process of continuity of real variable functions. To achieve this, a documentary research design with a qualitative approach and a descriptive depth level was adopted. The instruments for data collection and analysis included a search log, a bibliographic matrix, and a synthesis matrix, created using Excel software. The technique used for the literature review was qualitative content analysis, based on deductive analytical categories: objective, theoretical framework, research method, and conclusions. Advanced searches were conducted on Google Scholar, on Scopus and Web of Science and out of the total results found, 13 relevant articles published during the period 2020-2023 were selected. Among the main findings, the use of a variety of theoretical frameworks in the foundation of the analysed studies was identified, such as the theory of semiotic representations, the MTSK model, the TPACK, and the conceptual contributions of Tall and Vinner, among others. Additionally, a growing interest in the use of technological tools, such as GeoGebra, to enhance the teaching and learning process of mathematics in general, and the continuity functions in particular. Although its limitations, it was identified that this software can be used as a tool for visualization, construction, representation and communication of mathematical knowledge.
