PURPOSE The purpose of this study was to test the hypothesis that two lexical characteristics - neighborhood density and word frequency - interact to influence performance on phoneme awareness tasks. METHODS Phoneme awareness was examined in a large, longitudinal dataset of 2nd and 4th grade children. Using linear logistic test model, the relation between words' neighborhood density, word fre...

This paper is mainly concerned to give an overview of the programs currently running at Stanford in computer-assisted instruction. These are the drill-and-practice program in elementary mathematics, the tutorial mathematics program for grade 2 , the tutorial reading program for grade 1. the tutorial logic and algebra program for grades 5 to 8 , the tutorial Russian program at the university lev...

The purpose of the present study is to investigate the boundary layer separation point in a magnetohydrodynamics diffuser. As an innovation, the Re value on the separation point is determined for the non-Newtonian fluid flow under the influence of the non-uniform magnetic field due to an electrical solenoid, in an empirical case. The governing equations include continuity and momentum are solve...
