Flexible mental computation: What about accuracy?

Heirdsfield, Ann M. (2002) Flexible mental computation: What about accuracy? In Cockburn, A. & Nardi, E. (Eds.) 26th Annual Conference of the International Group for the Psychology of Mathematics Education., July, Norwich, UK.


Flexibility in strategy choice in mental computation is considered to be a component of number sense. This paper reports on an investigation into cognitive, metacognitive, and affective factors that support both flexibility and accuracy in mental addition and subtraction in Year 3 students. While some factors appeared to be essential for flexibility, additional factors were necessary for accurate employment of strategies. Further, there were qualitative differences between the mental strategies employed by the students who were accurate and those who were inaccurate.

Search Google Scholar™

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
