This dissertation was designed to examine the impact school-based mentor programs have on school connectedness when compared to a control group with no mentoring. Further, the study was designed to determine the differential impact between peer mentoring and adult mentoring. The research study was also designed to provide data to inform the…

This study investigated gender differences in the effect of PAL (peer-assisted learning) on students' mathematics performance in Enugu State of Nigeria. It used pre-test and post-test non-randomized control group design. Four research questions and four hypotheses guided the study. The population was SS II (senior secondary school class II)…

This article offers a brief and personal account of the historical background, implementation and principal findings from the Trois-Rivieres regional project, a large-scale quasi-experimental intervention that tested the impact of providing a daily hour of specialist-taught quality physical education upon the physical and mental development of…

Children from low socioeconomic backgrounds (SES) are at increased risk of reading problems. Although phonological awareness consistently emerges as a critical literacy skill for children, little research exists regarding the effects of the acquisition of phonological awareness skills on decreasing the reading achievement gap between children of…

The development of script schema, as a source of narrative knowledge, is an essential stage in this knowledge construction. This study focused on the role of bilingual versus monolingual preschool education in the development of script schema knowledge in Russian (L1) and Hebrew (L2) among Russian/Hebrew-speaking children in Israel. The preschool…

This research explores the role of affect in the domain of human wayfinding by asking if increased motivation will alter the performance across various routes of increasing complexity. Participants were asked to perform certain navigation tasks within an indoor Virtual Reality (VR) environment under either motivated and not-motivated instructions.…

Objective: Transverse relaxation time (T2) imaging provides the opportunity to examine membrane fluidity, which can affect a number of cellular functions. The objective of the present work was to examine T2 abnormalities in children with unmodified DSM-IV-TR bipolar disorder (BD) in bilateral cingulate-paracingulate (CPC) white matter. Method: A…

Retrieval of memories is enhanced when bilateral saccades are made immediately before attempting retrieval. One hypothesis is that saccades enhance retrieval by increasing interaction of the brain hemispheres. To test this, subjects viewed arrays of lateralized letters and indicated whether target letters matched either of two probe letters.…

Our study addresses the scope of phonological advance planning during sentence production using a novel experimental procedure. The production of German sentences in various syntactic formats (SVO, SOV, and VSO) was cued by presenting pictures of the agents of previously memorized agent-action-patient scenes. To tap the phonological activation of…

Introduction: Little is known regarding how to accomplish large-scale health care improvement. Our goal is to improve the quality of chronic disease care in all primary care practices throughout North Carolina. Methods: Methods for improvement include (1) common quality measures and shared data system; (2) rapid cycle improvement principles; (3)…

Meta-analysis of studies with two groups and two measurement occasions must employ order-one effect size indices to represent study outcomes. Especially with non-random assignment, non-equivalent control group designs, a statistical analysis restricted to post-treatment scores can lead to severely biased conclusions. The 109 primary studies…

"t"-Tests are widely used by researchers to compare the average values of a numeric outcome between two groups. If there are doubts about the suitability of the data for the requirements of a "t"-test, most notably the distribution being non-normal, the Wilcoxon-Mann-Whitney test may be used instead. However, although often…

Does time spent in a cohabiting relationship prior to marriage lead to more egalitarian housework arrangements after marriage? Previous research has shown that housework patterns within cohabiting relationships are more egalitarian than in marital relationships. But do these patterns remain when couples marry? The findings from previous studies…

The conjunction fallacy has been cited as a classic example of the automatic contextualisation of problems. In two experiments we compared the performance of autistic and typically developing adolescents on a set of conjunction fallacy tasks. Participants with autism were less susceptible to the conjunction fallacy. Experiment 2 also demonstrated…

In some experimental evaluations of classroom-level interventions it is not practically feasible to randomly assign teachers to experimental conditions. Given such restrictions, researchers may randomly assign students to experimental conditions and consider the teacher to be a part of the intervention. However, in an individually randomized…
