Eighteen parents participated in a Deliberate Psychological Education program designed to enhance their moral judgement and indirectly influence the moral development of their children. In a quasi-experimental nonequivalent control group design, their progress was compared to that of 19 participants in a no-treatment control condition. There was a…

Seventy 8th-grade students (including talented writers, those with average ability, and students in need of special education services) participated in an integrated social studies and language arts unit designed to promote historical understandings and argumentative writing skills.

This study investigates the effect of a training course, based on constructivism, on the student teachers' perceptions of teaching, learning and the roles of teachers and students in the teaching-learning process. A sample of 188 student teachers (92 of them in the experimental group and 96 in the control group) from the Hashemite University were…

The present investigation examined implicit and explicit memory in 20 children diagnosed with attention deficit/hyperactivity disorder (AD/HD) and 20 matched controls. Consistent with previous research, children with AD/HD performed more poorly than controls on an explicit test of long-term memory for pictures. New results were that (a) there was…

Background: In this study we used event-related potentials (ERPs) and source localization analyses to track the time course of neural activity underlying response monitoring in children diagnosed with an anxiety disorder compared to age-matched low-risk normal controls. Methods: High-density ERPs were examined following errors on a flanker task…

Background: Delays and deficits in joint attention and symbolic play constitute two important developmental problems in young children with autism. These areas of deficit have been well studied in autism but have rarely been the focus of treatment efforts (see Kasari, Freeman, & Paparella, 2001).

The purpose of this study was to determine the effectiveness of an alcohol gel as an adjunct to handwashing in…

This study investigated the impact of the TI-92 handheld Computer Algebra System (CAS) on student achievement in a discrete mathematics course. Specifically, the researchers examined the differences between a CAS section and a control section of discrete mathematics on students' in-class examinations. Additionally, they analysed student approaches…

The short- and long-term effects of quality physical education programs have been a subject of considerable debate by educational administrators and state legislators during the past decade. While physical educators have repeatedly demonstrated the importance of daily moderate and vigorous physical activity on the immediate health and wellbeing of…

The present study evaluated the efficacy of a sexual assault risk-reduction program that included a physical self-defense component for college women ("N"=500). Program group women significantly increased their protective behaviors over the 6-month follow-up period compared to the waiting-list control group. However, there were no significant…

This study reports on the leisure time, financial, gambling, and social activities of a large sample of children with hyperactivity (H group, N = 149) and children who served as a control group (CC group, N = 72) from the Southeastern Wisconsin (Milwaukee) region tracked for 13-15 years to young adulthood (ages 19--25, M = 20 years). Participant…

The relative effectiveness of explicit instruction, guided discovery, and discovery learning techniques in enhancing anticipation skill in young, intermediate-level tennis players was examined. Performance was assessed pre- and postintervention, during acquisition, and under transfer conditions designed to elicit anxiety through the use of…
