Abstract

Conceptual difficulties and visual representation barriers are often major challenges in learning integers, especially related to understanding negative numbers and mathematical operations such as addition and subtraction. This study aims to identify the problems faced by students in learning integers, evaluate the effectiveness of various teaching methods, and propose innovative approaches to improve students' understanding. The methodology used is a systematic review based on Systematic Literature Review (SLR), by analyzing relevant research articles using PRISMA guidelines. This study examines various learning strategies, such as the use of realistic contexts, innovative visual models, manipulatives, and interactive technology. The results showed that a real-world context- based approach and the use of visual models can significantly improve students' understanding compared to conventional methods. Students who engaged in manipulative-based learning and class discussions also showed better mathematical thinking flexibility. These findings highlight the need for further exploration of the use of real contexts, more innovative visual models, and the application of gamification technology in integer learning. In conclusion, integer learning requires a more innovative approach by integrating realistic contexts, new visual models, and interactive technology. This not only increases student engagement but also supports the development of conceptual and procedural abilities more effectively.

Abstract

This study aims to describe elementary students’ procedural fluency in solving fraction addition problems using the built-in definition fraction media. Fraction operations are often challenging for students, particularly when determining common denominators and applying calculation procedures accurately. These difficulties are commonly associated with weak procedural understanding and limited opportunities to use concrete learning media. This descriptive study involved 30 fourth-grade students from SDN 204 Palembang who had previously learned basic fraction concepts. Data were collected through a written test consisting of three levels of procedural fluency tasks and supported by interviews to explore students’ reasoning processes. The results show that 47% of students were able to solve fraction addition problems with denominators (Level 1), 33% managed tasks involving adjustment of one denominator (Level 2), and only 13% successfully solved problems requiring the determination of the least common multiple of denominators (Level 3). These findings indicate that students’ procedural fluency development is not linear but constrained at transition points from concrete visual manipulation to abstract procedural reasoning. While the built-in definition fraction media effectively supported early procedural stages by strengthening visual–procedural connections, it was less effective in facilitating higher-level abstraction required for complex fraction operations. The study contributes to procedural fluency literature by identifying specific procedural transition points where students begin to experience difficulties.
