Agricultural education very early on tested a generalized mandate of modular interdisciplinary education. In this regard, it constitutes an interesting medium for observing the conditions required for developing interdisciplinarity in an academic context. Based on a historical approach, this text shows how a series of experiments led to a…

Rough-and-tumble play, or play fighting, is common in the young of many mammals. Research on play fighting among rats shows that there are many levels of neural control over this behavior: subcortical mechanisms mediate the motivation and behavior of such play, and the cortex provides mechanisms by which the play changes with age and context. The…

The construct of cognitive complexity has played an increasingly important role in studies on task design, which aim to explore how increases in the cognitive complexity of tasks differentially mediate interaction and learning outcomes (Kim, 2009; Gilabert, Baron, & Llanes, 2009; Kim & Tracy-Ventura, forthcoming; Nuevo, 2006; Revesz, 2009,…

This quantitative study was developed to determine the influence tactic used most often by teachers in a small college classroom. It was hypothesized that the rational persuasion tactic, which is defined as "using logical arguments and factual evidence to persuade the target". (Fu & Yukl, 2000, p. 252) would be the most commonly employed tactic by…

The impact of eliminating extraneous sound and light on students' achievement was investigated under four conditions: Light and Sound controlled, Sound Only controlled, Light Only controlled and neither Light nor Sound controlled. Group, age and gender were the control variables. Four randomly selected groups of high school freshmen students with…

The authors of this study examine how evaluations made during an early stage of the structured interview (rapport building) influence end of interview scores, subsequent follow-up employment interviews, and actual internship job offers. Candidates making better initial impressions received more internship offers (r = 0.22) and higher interviewer…

We developed a dual-level transformational leadership scale to measure individual-focused behavior at the individual level and group-focused behavior at the group level, and we validated the scale using a sample of 203 members from 60 work groups in a Canadian company. Results show that individual-focused leadership behavior, at the individual…

Relational forms of aggression are known to increase during the middle school years. To date, the majority of efficacy studies of elementary school-based programs have focused on the reduction of physical and direct verbal aggression, to the exclusion of effects on relational aggression. "Steps to Respect: A Bullying Prevention Program" is one…

Social trust (i.e., belief that people are generally fair and trustworthy) is important to the functioning of democracies, and trend studies show it has declined. We test hypotheses concerning the development of these beliefs in adolescence. Based on surveys of 1,535 adolescents collected over 2 years, we find that middle and late adolescents had…

This study uses a work stress theoretical framework to examine the effects of direct and indirect client violence on a randomly selected national sample of MSW and BSW social work students from the National Association of Social Workers (N=595). Client violence variables were analyzed in relationship to fear of future violence and occupational…

Critical thinking is a valued educational outcome; however, little is known about whether psychology courses, especially ones such as research methods courses that might be expected to promote critical thinking skills, actually improve them. We compared the acquisition of critical thinking skills for analyzing psychological arguments in 3 groups…

Studies show that children who use relational aggression process social information in unique ways; however, findings have been inconsistent and limited by methodological weaknesses. This short-term longitudinal study examined developmental changes in 245 (49% female; ages 8-13) 3rd through 8th graders' normative beliefs about relational…

This study examined the effect of summarization as a generative learning strategy of the readers' performance on reading comprehension, in general, and reading comprehension display, referential and inferential questions in particular. The subjects in this study were 61 high school students. They were assigned to two groups--control and…

This article demonstrates how the broad and narrow abilities and processes that comprise Cattell-Horn-Carroll (CHC) theory and their relations to specific academic outcomes have begun to transform our current understanding of the definition of and methods for identifying specific learning disability (SLD), particularly in the school setting. The…

Deliberate practice--meaning drill-like practice under the direction of a coach--is key to developing expertise in sports and music. But working professionals and businesspeople typically have no time for practice. We propose deliberate performance as a type of practice that professionals and businesspeople can pursue while they work as a way to…
