|Title:||A Developmental Scale of Mental Computation with Part-Whole Numbers||Contributor(s):||Callingham, Rosemary Anne (author); Watson, J (author)||Publication Date:||2004||Handle Link:||https://hdl.handle.net/1959.11/1636||Abstract:||In this article, data from a study of the mental computation competence of students in grades 3 to 10 are presented. Students responded to mental computation items, presented orally, that included operations applied to fractions, decimals and percents. The data were analysed using Rasch modelling techniques, and a six-level hierarchy of part-whole computation was identified. This hierarchy is described in terms of the three different representations of part-whole reasoning – fraction, decimal, and percent – and is elaborated by a consideration of the likely cognitive demands of the items. Discussion includes reasons for the relative difficulties of the items, performance across grades and directions for future research.||Publication Type:||Journal Article||Source of Publication:||Mathematics Education Research Journal, 16(2), p. 69-86||Publisher:||Mathematics Education Research Group of Australasia||Place of Publication:||Melbourne, Australia||ISSN:||1033-2170||Field of Research (FOR):||130303 Education Assessment and Evaluation||Peer Reviewed:||Yes||HERDC Category Description:||C1 Refereed Article in a Scholarly Journal||Other Links:||http://www.merga.net.au/documents/MERJ_16_2_Callingham.pdf||Statistics to Oct 2018:||Visitors: 226
