Research indicates that engagement acts as an important precursor for learning, yet sustaining the engagement of pupils with special educational needs can be a challenge for classroom staff. An Active Support staff training package, Interactive Training, has been demonstrated as an effective way of increasing engagement in adults accessing learning disability services. In theory the logic of Active Support Interactive Training could extend to a school environment, with the aim of achieving similar outcomes. The current study evaluated a special school-adapted version of Active Support Interactive Training with the aim of increasing engagement in pupils during group-based learning. Findings showed an increase in engagement in pupils for all three settings (classrooms) immediately after intervention, which continued to either increase or stabilise at three-month follow-up. Further research could test the engagement behaviour of staff pre- and post- training intervention and explore practice leadership within the school leadership team to address maintenance.  相似文献

ABSTRACT

Participation in youth sport is positively associated with physical fitness and performance. The purpose of the current study was to examine if physical fitness measures during childhood and early adolescence predicted high school sport participation. Participants included youth in the Michigan State University Motor Performance Study. Measures consisted of the endurance shuttle run, Wells sit-and-reach, jump and reach, standing long jump, agility shuttle run and 30-yard dash. Individual, generalized estimating equation models were used to estimate the association between each measure and the odds of participating in high school sport. For both sexes, the endurance shuttle run and agility shuttle run were related to sport participation. For boys only, the long jump and 30-yard dash were also associated with sport participation. Better physical fitness and performance across several dimensions in childhood, including those related to motor skills, enhanced the likelihood of sport participation in high school.  相似文献

According to the goal orientation model, students’ achievement goals and beliefs are interrelated. Within this framework, research and theory have so far assumed that achievement goals are associated with students’ beliefs of causes of success, the latter representing students’ subjective beliefs about the factors contributing to success at school. So far, this line of research has been restricted to a few cross-sectional studies. We examined the temporal relations between achievement goals (mastery, performance-approach, and performance-avoidance goals) and students’ beliefs of causes of success, the latter operationalized by asking the students to rate the subjective importance of diligence, effort, and ability for school success. Achievement goals and beliefs of causes of success were measured twice with a time lag of one school year with a sample of N = 2044 German secondary school students. Cross-lagged panel models were estimated to examine the temporal relations between achievement goals and beliefs of causes of success while controlling for students’ secondary school track, socio-economic status, and Grade Point Average. Former mastery goals were found to be positively related to later importance ratings of diligence for school success; former performance-approach goals were found to be positively related to later importance ratings of ability. Boys and girls were found to display similar relations among constructs but they showed differential mean levels on both the achievement goal constructs and the beliefs of causes of success. Implications for research on achievement goals and practice using intervention approaches are discussed.  相似文献

In social networking services (SNSs), users’ unclear understanding of the large and invisible audience increases the chances of online turbulence, which is a key source of SNS-induced stress. This growing phenomenon has gained increasing attention in academia and industry due to the undesirable consequences for users and SNS platforms. In this study, we draw from the transactional model of stress to examine how audience management strategies impact online turbulence and lead to neglected unintended audience concern and lurking. We also investigate the role of self-monitoring as a stress inhibitor. We test our model with data collected from 301 SNS users. The results show that the four types of audience management strategies have different effects on online turbulence, which significantly impacts neglected unintended audience concern especially when users have high self-monitoring skills. We believe that this work contributes, both from scientific and practical standpoints, to the understanding of the interventions and stressful responses of online turbulence in SNSs.  相似文献

ABSTRACT

Meta-analytic evidence supports that exercise has benefits for short-term memory (STM) and long-term memory (LTM). However, only three studies with children have tested the differential effects of exercise on STM and LTM. The purpose of this study was to examine the effects of an aerobic fitness test on STM and LTM and to consider the moderating effects of grade level. Children (7–13 years of age) were randomly assigned to either perform an aerobic fitness test before (exercise prior) or after (exercise post) performing the Rey Auditory Verbal Learning Test (RAVLT) to assess memory. Memory was tested again after approximately 24 hours. There were significant differences in memory performance as a function of grade with 4th and 6th graders consistently outperforming 2nd graders. For learning, Day 1 Retention, 24-hr recall, and Day 2 Retention, the exercise prior group performed better than the exercise post group. It is concluded that an aerobic fitness test performed prior to a declarative memory test benefits LTM as compared to when the aerobic fitness test is performed after the memory test.  相似文献

Drawing upon the causal agency theory, this study examined the direct and indirect (via learning approaches) links between positivity and quality of college life (QCL) of business students in a transitioning market, Vietnam. Two studies were conducted to test these relationships using structural equation modeling. Findings from study 1, based on a sample of 428 business students, showed that positivity was positively related to QCL. Further, deep learning approaches mediated the relationship between positivity and QCL. Findings from study 2, based on a sample of 416 business students, reconfirmed the role of positivity in QCL. However, the indirect relationship between positivity and QCL was not significant, demonstrating that surface learning approaches did not mediate the relationship between positivity and QCL. The findings contribute to the literature on positivity in higher education by confirming the overarching role that positivity plays, directly and indirectly (via deep learning approaches), in QCL.  相似文献
