This study investigated the change in student mental computation strategies for addition and subtraction following eight half-hour lessons over an eight-week period. The principal researcher provided the teacher with a theoretical background for mental computation and support materials for the development of the instructional program. Twenty-one Year 2 students participated in pre- and post-testing using individual interviews to identify the students’ mental computational methods. The results indicated that students who employed inefficient methods such as counting moved to more sophisticated strategies such as wholistic compensation. Other students who already employed some sophisticated strategies increased their repertoire.

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.
