The purposes of this study were to examine the relations of both family and school contexts on students' academic achievement and to explore the mediating effects of students' perceptions of their motivations and academic self‐competence between the family and school contexts and achievement. Participants were 230 fifth‐ and sixth‐grade students. Students' perceptions of parenting style (demandingness and responsiveness), parental involvement (parental values and involvement in school functions), teaching style (teacher control and responsiveness), and school atmosphere (school responsiveness and supportive social environment) significantly predicted their school achievement; however, students' motivations and self‐competence mediated the relations between students' contexts and their academic achievement. Furthermore, parental values, teacher responsiveness, school responsiveness, and supportive social environment predicted students' motivations and academic competence above and beyond parenting style, parental involvement, and teacher control. The importance of students' supportive relationships and the internalization of the messages conveyed to them underscore the need for a contextual view by school psychologists when consulting with parents and education staff regarding achievement concerns. © 2001 John Wiley & Sons, Inc.  相似文献

The purpose of this study was to examine relationships between functional movement screen scores, maturation and physical performance in young soccer players. Thirty males (11–16 years) were assessed for maturation, functional movement screen scores and a range of physical performance tests (squat jump, reactive strength index protocol and reactive agility cut). Older players significantly outperformed younger participants in all tests (P < 0.05; effect sizes = 1.25–3.40). Deep overhead squat, in-line lunge, active straight leg raise and rotary stability test were significantly correlated to all performance tests. In-line lunge performance explained the greatest variance in reactive strength index (adjusted R2 = 47%) and reactive agility cut (adjusted R2 = 38%) performance, whilst maturation was the strongest predictor of squat jump performance (adjusted R2 = 46%). This study demonstrated that variation of physical performance in youth soccer players could be explained by a combination of both functional movement screen scores and maturation.  相似文献

The aim of this study was to use video evidence of tackles in elite level rugby union to identify ball carrier proficiency characteristics, for both lower and upper body tackles, that have a higher propensity to result in Head Injury Assessments(HIA) for the tackler. HIA (n = 74) and non-HIA tackles (n = 233) were categorised as either front-on or side-on upper or lower body tackles and scored for ball carrying proficiency characteristics. Side-on tackles included tackles from behind. A Chi-Square test (p < 0.05) and Cramer’s V were calculated to compare proficiency characteristics in HIA and non-HIA cases. For front-on upper body tackles, the ball carrier “fending into contact” (p < 0.01;ES = Moderate) and “explosiveness on contact” (p = 0.04;ES = Moderate) had a higher propensity to result in a HIA for the tackler. Fending into contact was exhibited in 47% of all upper body Tackle front-on HIA cases. The fending arm contacted the tackler’s head in 67% of these cases. Fending into contact can potentially be dangerous and therefore emphasis should be placed on safe fending during tackle-based training drills. Referees should also be alert to arm-to-head contact during the fend. Given the low number of ball carrier characteristics identified, focus should be placed on tackler characteristics for HIA prevention strategies.  相似文献

Eighty-four children from rural, urban, and suburban families were tested with the PPVT during a parent intervention program and with the SIT three years later as part of program evaluation. Results indicated the mean IQ on the SIT was substantially higher than expected based on the earlier PPVT scores. Sampling error and examiner error were excluded as explanations for the difference. These results suggest that the PPVT and SIT yield different scores and lack comparability.  相似文献

Directors of American Psychological Association (APA)-approved school psychology programs were surveyed to determine what responsibilities and benefits attend their role as training director; they also were asked to identify what they liked about serving in the training director role. Of 42 possible respondents, 33 (79%) returned usable questionnaires. Several responsibilities that all or virtually all of the training directors engaged in were identified (e.g., end-of-year APA report preparation); many respondents (61%) received release time from a class, but otherwise any benefits they received were few; and several important, motivating reasons (e.g., contributing to the future of school psychology) for functioning as a training director were identified. The implications of these findings for school psychology programs are briefly discussed.  相似文献

To date, most studies of the efficacy of Facilitated Communication (FC) have been hampered by small samples, limited experience of the subjects with the FC, and diagnostically narrow samples. The present study has a comparatively large sample, and the subjects each had a minimum of one year's experience using FC. Diagnoses of the subjects were also arrayed across a broad spectrum. Pictorial stimuli that had been used as classroom teaching materials were presented to each subject and facilitator under three different conditions of five trials each. Responses were rated by independent judges who were not aware of the stimuli. Support for the communicative value of FC was not found.  相似文献
