The impact of training nine first- and second-grade children to use a self-instruction regimen (overt verbalization of self-instructions) and/or an accuracy regimen was investigated. Children improved dramatically in academic accuracy subsequent to self-instructional training regardless of whether accuracy or self-instruction use were reinforced.…

The purpose of this paper is to offer three alternatives to patterns or visualization used to justify division of fraction "algorithm" invert and multiply". The three main approaches are historical, similar denominators and algebraic, that teachers could use to justify the standard algorithm of division of fraction. The historical approach uses…

Reading and number readiness activities for use in teaching children are given. (DB)

Twenty-six monolingual and 46 bilingual college students were assigned to 2 groups on the basis of their performance on a complex relational task, an empirical model of instructional control (O'Hora, Barnes-Holmes, Roche, & Smeets, 2004). The subjects were then exposed to the vocabulary, arithmetic, and digit-symbol encoding subtests of the…

This study examined whether knowledge of arithmetic contributes to difficulties with equations. In Experiment 1, children (ages 7-11) completed tasks to assess their adherence to 3 operational patterns prevalent in arithmetic: (a) the strategy of performing all given operations on all given numbers, (b) the "operations=answer" problem structure,…

Some procedures are developed for testing divisibility by prime numbers composed of two or more digits. Accelerating the tests is also considered. (Contains 2 tables.)

This article illustrates how the arithmetic series 1 + 2 + 3 + ... + n is pervasive in mathematical contexts as a powerful problem-solving tool.

This primary goal of this study was to investigate the effects of strategy training and self-reflection, two subprocesses of Zimmerman's cyclical model of self-regulation, on fifth grade students' mathematics performance, self-efficacy, self-evaluation, and calibration measures of self-efficacy bias, self-efficacy accuracy, self-evaluation bias,…
