The purpose of this study was to validate and extend the findings of an exhaustive literature search in Year 1 and a meta-analysis in Year 2 of a 3-year project in which nine (9) small-group discussion approaches were identified. Having identified parameters of discussion that were, to a greater or lesser extent, present in these nine discussion approaches, our goal in the study being reported in this paper, was to evaluate the nine discussion approaches on a common set of discourse features known to characterize ‘quality’ discussions. Although there is overlap among some studies in the nature of the measures used, the extant literature does not afford a uniform basis on which to evaluate student talk as an indicator of student understanding and critical thinking. In the present study, we identified features of classroom discourse that might serve as proximal indices of students’ learning and comprehension and we employed each of these proximal indices in analyzing and evaluating the discourse samples solicited from the proponents of the discussion approaches. 相似文献

Many new research advancements have been gained in fields other than the basic social sciences. Some of these advancements come from multidisciplinary studies that merge social sciences with theories from other fields of study. This article takes a multidisciplinary approach, juxtaposing some of the more recent findings from other disciplines to develop a general model for improving performance. The proposed model utilizes social theory from sociology and community studies, knowledge spirals from the knowledge management discipline, motivation theories derived in part from evolutionary biology, and research on engagement from different fields of study within the social sciences. By incorporating a multidisciplinary theory for performance improvement, the authors are adhering to recommendations from researchers calling for alternative paradigms to be utilized, providing a more holistic understanding of the phenomena being studied (Storberg‐Walker, 2007 ; Torraco, 2004 ). 相似文献

Early experiences of maltreatment have long-term negative effects on children's compliance. This randomized clinical trial examined whether a brief preventative intervention (Attachment and Biobehavioral Catch-up; ABC) was effective in enhancing compliance in children who had been referred to Child Protective Services. Participants included 101 parent–child dyads who received either ABC or a control intervention when children were infants (M = 9.4 months old, SD = 6.1). When children were approximately 36 months old (M = 38.5, SD = 3.0), ABC children demonstrated significantly better compliance than control children. Further, parent sensitivity, measured 1 month post intervention when children were, on average, 18.4 months old (SD = 6.9) partially mediated the effect of ABC on child compliance at 36 months old. 相似文献

The neurodevelopmental sequelae of early deprivation were examined by testing ( N = 132) 8- and 9-year-old children who had endured prolonged versus brief institutionalized rearing or rearing in the natal family. Behavioral tasks included measures that permit inferences about underlying neural circuitry. Children raised in institutionalized settings showed neuropsychological deficits on tests of visual memory and attention, as well as visually mediated learning and inhibitory control. Yet, these children performed at developmentally appropriate levels on similar tests where auditory processing was also involved and on tests assessing executive processes such as rule acquisition and planning. These findings suggest that specific aspects of brain-behavioral circuitry may be particularly vulnerable to postnatal experience. 相似文献

The present study evaluated the effectiveness of an instructional intervention (schema-based instruction, SBI) that was designed to meet the diverse needs of middle school students by addressing the research literatures from both special education and mathematics education. Specifically, SBI emphasizes the role of the mathematical structure of problems and also provides students with a heuristic to aid and self-monitor problem solving. Further, SBI addresses well-articulated problem solving strategies and supports flexible use of the strategies based on the problem situation. One hundred forty eight seventh-grade students and their teachers participated in a 10-day intervention on learning to solve ratio and proportion word problems, with classrooms randomly assigned to SBI or a control condition. Results suggested that students in SBI treatment classes outperformed students in control classes on a problem solving measure, both at posttest and on a delayed posttest administered 4 months later. However, the two groups’ performance was comparable on a state standardized mathematics achievement test. 相似文献

This study investigated the change in body composition and bone mineral content (BMC) of senior rugby league (RL) players between 2008 and 2014. Twelve male professional RL players (age, 24.6 ± 4.0 years; stature, 183.4 ± 8.4 cm) received a dual-energy X-ray absorptiometry scan during preseason in 2008 and 2014. Between 2008 and 2014, very likely increases in leg lean mass (LM), total trunk and leg BMC, and a likely increase in arm BMC and possible increases in body mass (BM), total and trunk fat mass (FM), and total, trunk and arm LM were observed. Unlikely decreases and unclear changes in leg and arm FM were also found. Large negative correlations were observed between age and BM (r = ?0.72), LM (r = ?0.70), FM (r = ?0.61) and BMC (r = ?0.84) change. Three participants (19.1 ± 1.6 years) increased LM by 7.0–9.3 kg. Younger players had the largest increases in LM during this period, although an older player (30-year old) still increased LM. Differences in body composition change were also observed for participants of the same age, thus contextual factors should be considered. This study demonstrates the individuality of body composition changes in senior professional rugby players, while considering the potential change in young athletes. 相似文献
