One conditioned taste aversion experiment with rats assessed the impact of extinguishing a target conditioned stimulus (CS), S, in compound with a second CS, A, upon conditioned responding elicited by CS S when presented alone at test. Following initial conditioning treatment with CSs A and S, the experiment manipulated number of extinction trials…

Purpose: The paper aims to examine the effect of implementing participatory school administration, leadership and management (PSALM) on the levels of empowerment among the educational stakeholders. Design/methodology/approach: A mixed method approach, combining the experimental design with empirical surveys, interviews and documentary analysis,…

The purpose of this study is to design a constructivist learning environment that helps learning the limit concept. The study is a pretest-posttest quasi-experimental research. The control and the experimental groups were chosen from the students attending a calculus course. Worksheets were used to assess students' learning of the limit concept.…

Electronic performance support system (EPSS) technology provides a powerful mechanism for helping end-users operate complex systems. This article describes and discusses some research we have undertaken to explore their potential within academic library systems. Based on a needs analysis, an EPSS for supporting library users was designed and…

To provide an overview of the specific components that must be considered when making decisions about research in the field of gifted education, the authors describe and evaluate the three types of evidence--speculative or anecdotal, theoretical, and empirical--commonly offered in the literature of the field. Empirical, or evidence-based, research…

The development of phonological awareness (PA) before school age was modeled in association with the development of vocabulary and letter knowledge, home literacy environment (HLE), children's reading interest, and beginning reading skill in children with and without familial risk of dyslexia. A total of 186 children were followed from birth to…

The Test of Language Competence-Expanded Edition (TLC-E) was administered to children and adults with a diagnosis of autism spectrum disorder (ASD). Relative to controls, those with ASD were less competent on a range of TLC-E tasks. No differences were found for either child or adult ASD groups on any of the TLC-E measures when re-classified as…

The Predominantly Inattentive (PI) and Combined (CB) subtypes of AD/HD differ in cognitive tempo, age of onset, gender ratio, and comorbidity, yet a differentiating endophenotype has not been identified. The aim of this study was to test rigorously diagnosed PI, CB, and typical children on measures selected for their potential to reveal…

This current study introduced a new method to investigate the prevalence and correlates of significant imbalances in the relative accuracy with which eighth-graders read nonwords (e.g., "prauma") and exception words (e.g., "vaccine"). Substantial proportions of students showed imbalanced word-reading profiles, but these were…

Two studies explored the role of implicit theories of intelligence in adolescents' mathematics achievement. In Study 1 with 373 7th graders, the belief that intelligence is malleable (incremental theory) predicted an upward trajectory in grades over the two years of junior high school, while a belief that intelligence is fixed (entity theory)…

Purpose: Previous studies (e.g., G. Wulf, M. HoB, & W. Prinz, 1998; G. Wulf, B. Lauterbach, & T. Toole, 1999; for a review, see G. Wulf & W. Prinz, 2001) have reported that limb motor performance is enhanced when individuals adopt an external focus (focusing on the effect of the movement) versus an internal focus of attention (focusing on body…

The purpose of this study was to determine the nature and efficiency of the strategies used by prelingually deafened native signers for the temporary retention of written words with reference to a primary language-coding hypothesis (M. A. Shand, 1982). For the gathering of the data, participants were shown lists of serially presented written…

This study reports on a three-semester model project designed to assess the impact of enriched content related to Women's and Gender Studies on students enrolled in an undergraduate ecology course. The two constructs of interest were (a) students' attitudes toward women in science and society and (b) students' assessment of the classroom climate…

In an attempt to find ways to improve persistence rates in its distance courses, the Cegep@distance introduced different forms of collaboration (peer interaction and collaborative learning activities) in selected courses. A mixed methodology was used to understand the effects of these interventions, relying on a quasi-experimental design for the…

A randomized controlled trial was used to evaluate a parent training intervention for caregivers with preschool-age children with developmental disabilities. The 21 families in the experimental group received usual care plus the 12-week Incredible Years Parent Training Program with developmental delay modifications. Families in the control group…
