Creative Mathematical Reasoning of Prospective Teachers in Solving Problems Reviewed Based on Working Memory Capacity

摘要

Reasoning requires logical thinking in solving problems, and working memory capacity becomes something important. This study aimed at investigating the creative mathematical reasoning of prospective teachers in solving problems reviewed based on working memory capacity. This research was qualitative. The study conducted at Indonesian Christian University of Toraja to Mathematics Education study program students. The selection of research subjects was done by giving operation span (O-SPAN) assignments to select 1 student with a high category of working memory capacity and 1 student with a low category of working memory capacity. Then they were given a creative mathematical reasoning test and interview. Based on the data analysis, it obtained that the creative mathematical reasoning of prospective teachers in solving problems on the research subject who had low working memory capacity showed creativity and plausibility criteria but it did not show anchoring because he could not provide arguments that supported the selection of strategies based on mathematics. Furthermore, creative mathematical reasoning of prospective teachers in solving problems on the research subject who had high working memory capacity met the three criteria for creative mathematical reasoning, namely creativity, plausibility and anchoring.
