Abstract—Research on defragmentation in mathematics education has developed in response to the issue of fragmented thinking structures that often hinder students' success in solving mathematical problems. This Systematic Literature Review (SLR) aims to analyze findings from studies on defragmentation in addressing these challenges. A total of 17 peer-reviewed articles published between 2019 and 2024 in Scopus or SINTA-indexed journals were systematically and thematically analyzed. The results show that defragmentation strategies help students overcome various errors in mathematical problem-solving by enabling the diagnosis of thinking errors and supporting the design of more guided and coherent intervention strategies. The findings imply that defragmentation can serve as an alternative instructional strategy to strengthen students' conceptual understanding in mathematics learning.
