Abstract

The national mathematics curriculum revision process is underway in the background of the era where rapid technological development, uncertainty and volatility are expanded. In this process, consideration of matrix as a learning content emerged as one of the key issues, and conflicts among diverse educational participants are escalating. This study attempted to obtain implications for revising the presentation of matrix in textbooks by comparing the perspectives reflected in mathematics textbooks in Korea, Singapore, and Australia. First, the study compared and analyzed the learning contents, concept introduction and contents development methods in the textbooks from the three countries, and found that Korean textbooks cover more learning elements and tend to focus on calculation, while the other two textbooks from Singapore and Australia value the meaning of matrix as a useful means of expressing data. In addition, the results of comparing tasks based on the cognitive level framework developed by integrating the TIMSS cognitive domain and Jan de Lange’s framework showed that more than 80% of the tasks included in the Korean textbooks remained at the level of reproduction and connection, while Singapore and Australian textbooks provided various opportunities to learn such as making conjecture, justification and mathematical modeling through 70% and 45% of the tasks at the level of reflection, respectively. Drawing on the implications from the analysis, it is suggested to have fewer focus on content elements and more emphasis on conceptual understanding, mathematical reasoning, and mathematical modeling rather than calculation.
