Abstract

This paper reports on a study that examined the importance of multiplicative structure and whether, after several years of formal instruction in the decimal number system, Year 6 students had acquired an understanding of this structure. To this end, 173 Year 6 students were tested with a pencil-and-paper instrument developed to assess the decimal-number numeration processes that are normally taught in primary school and from which 45 students (32 high performing, 13 low performing) were selected for interviewing on tasks related to multiplicative structure. The interviews revealed that only the most proficient students (90% for tenths and hundredths in the test) had acquired a structural schema of multiplicativity that enabled access to application tasks.

Citation countsare 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.
