The process of effective teaching--teaching that directly leads to student learning of standards-based content--is tenuous at best and easily disrupted by contextual and behavioral factors. In this commentary, I discuss the role of student support and mediation in teacher effectiveness and curricular reform. The most vocal students in physical…

There are two major hypotheses concerning the developmental trends of processing speeds. These hypotheses explore both local and global trends. The study presented here investigates the effects of people's different knowledge on the speed with which they are able to process information. The participants in this study are gifted children aged 9,…

The main purpose of this paper is to present an ongoing research study on the evolution of pre-numerical and pre-inductive levels of ordinal thought in students from three to seven years old. Our methodology is based on multimedia technology, an automatic and objective record of the data and minimal interaction between students and researcher. A…

Purpose: This study examined language productivity and syntactic complexity in school-age children in relation to their knowledge of the topic of discussion--the game of chess. Method: Children (N = 32; mean age = 10;11 [years;months]) who played chess volunteered to be interviewed by an adult examiner who had little or no experience playing…

As children develop, they process information more rapidly. The primary aim of this study was to determine whether processing speed in the language domain develops at the same rate as global processing speed. A second aim was to determine the stability of processing speed throughout childhood and adolescence. Children (N = 116) were tested on 10…
