Julie, Cyril – International Journal of Mathematical Education in Science and Technology, 2020
A widely used instrument was implemented to ascertain the mathematical modelling competency displayed by a cohort of South African learners in grade 10 and grade 12 of the school mathematics programme in South Africa. The cohort comprised 471 grade 10 and 200 grade 12 learners from schools serving learners from low socio-economic status…

Weyns, Anke; Van Dooren, Wim; Dewolf, Tinne; Verschaffel, Lieven – Educational Psychology, 2017
We investigated the effect of emphasising the realistic modelling complexity in text or in the accompanying picture on the solution of P-items, in relation to pupils' grade. 290 pupils from the 5th and 6th grade of various elementary schools in Flanders (Belgium) made a paper-and-pencil task with 7 word problems that are problematic from a…

Wilson, Tim; Barkatsas, Tasos – Mathematics Education Research Group of Australasia, 2014
This study investigates the relationship between students ability to answer reduced language dependency mathematical questions with their overall numeracy level. It investigates whether a student's success at reduced language mathematical questions translates into better overall numeracy scores. It was found, students have up to two years…

National Centre for Vocational Education Research (NCVER), 2013
This publication presents estimates of apprentice and trainee activity in Australia for the September quarter 2012. The figures in this publication are derived from the National Apprentice and Trainee Collection no.74 (December 2012 estimates). The most recent figures in this publication are estimated (those for training activity from the March…

Madhyastha, Tara M.; Hunt, Earl; Deary, Ian J.; Gale, Catharine R.; Dykiert, Dominika – Intelligence, 2009
In longitudinal studies data is collected in a series of waves. Each wave after the first suffers from attrition. Therefore it can be difficult to discriminate between changes in sample parameters due to a longitudinal process (e.g. ageing) and changes due to attrition. The problem is particularly vexing if one of the purposes is to compare…

Brainerd, Charles J.; Howe, Mark L. – Child Development, 1980
The question of whether or not a certain mathematical model is applicable to the paired-associate data of preschool children as well as adults was examined in five experiments. (Author/MP)

Duraisamy, P. – Economics of Education Review, 2002
Provides estimates of the 1993-94 returns to education in wage employment in India by gender, age cohort, and location (urban-rural); also evaluates the changes in returns over the period 1983-94 using a large national-level household survey. Finds evidence, for example, of substantial gender and rural-urban differences in returns to schooling.…

Duran, Pilar; Malvern, David; Richards, Brian; Chipere, Ngoni – Applied Linguistics, 2004
This article discusses issues in measuring lexical diversity, before outlining an approach based on mathematical modelling that produces a measure, D, designed to address these problems. The procedure for obtaining values for D directly from transcripts using software (vocd) is introduced, and then applied to thirty-two children from the Bristol…
