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

Current conceptions of accountability imply that, in order for teachers to be able to hold themselves to account, they need first to have cultivated certain ‘professional dispositions’. But these conceptions fail to acknowledge the extent to which teachers are first and foremost accountable ‘as such’. For the early existentialist thought of the philosopher Jean‐Paul Sartre, this relates to a kind of responsibility premised on the ways in which we are always and inevitably responding to the world in which we find ourselves (with others). In this paper, I offer a reconceptualisation of teacher accountability in light of this, one that recognises implicit responses in classroom situations as underpinned by the subjectivity of those who bring these situations to light—often in subtle and immeasurable ways.  相似文献

This article considers the role of the SENCo during Covid-19 pandemic conditions of school lockdown with partial reopening for children classified as ‘vulnerable’. It is argued that the existing pressures and tensions already experienced by SENCos – for example, related to time, workload, status, and their prescribed managerial and strategic role – have been highlighted by pandemic conditions. Pressures resulting specifically from the pandemic are reflected by considering how SENCos will adjust to enact their role during this time. It is concluded that an advocacy role for pupils with special educational needs and disability, who are at risk of becoming increasingly marginalised within school and wider communities during this pandemic, should now be considered a central element of the SENCo’s remit.  相似文献

Early childhood is a sensitive period for learning and social skill development. The maturation of cerebral regions underlying social processing lays the foundation for later social-emotional competence. This study explored myelin changes in social brain regions and their association with changes in parent-rated social-emotional development in a cohort of 129 children (64 females, 0–36 months, 77 White). Results reveal a steep increase in myelination throughout the social brain in the first 3 years of life that is significantly associated with social-emotional development scores. These findings add knowledge to the emerging picture of social brain development by describing neural underpinnings of human social behavior. They can contribute to identifying age-/stage-appropriate early life factors in this developmental domain.  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

ABSTRACT

The present study aimed to provide reference values for lower-limb muscle power assessed during the incremental jump squat (JS) test in elite athletes (i.e., professional athletes competing at international level). We pooled data from all JS tests performed by elite athletes of different sports in two high-performance centres between 2015 and 2019, and computed reference values (i.e., terciles) for mean power (MP), mean propulsive power (MPP), and peak power (PP). Reference values were obtained from 684 elite athletes (458 male and 226 female) of 16 different sports (boxing, judo, karate, fencing, taekwondo, wrestling, basketball, soccer, futsal, handball, rugby union, badminton, tennis, long distance running, triathlon, and sprinting). Significant differences (p < 0.001) were found between male and female athletes for MP (7.47 ± 1.93 and 6.15 ± 1.68 W·Kg?1, respectively), MPP (10.50 ± 2.75 and 8.63 ± 2.43 W·Kg?1), and PP (23.64 ± 6.12 and 19.35 ± 5.49 W·Kg?1). However, the velocity at which these power measures was attained seemed to be independent of sex (~0.95, 1.00 and 2.00 m·s?1 for mean, mean propulsive, and peak velocity, respectively) and homogeneous across different sport disciplines (coefficient of variation <10%). These data can be used to classify athletes’ power capabilities, and the optimum velocity ranges provided here could be useful for training purposes.  相似文献

The purpose of this study was to test the directionality of influence between reading comprehension (RC) and print exposure (PE), thereby estimating genetic and environmental effects of this relation. The sample consisted of 910 twins in fourth through ninth grades (Mage = 12.33 years, SD = 1.41) from the Florida Twin Project on Reading, Behavior, and Environment. Using direction-of-causation model in a twin design, results supported a direction of influence running from RC to PE. This relation was underpinned by genetic and environmental factors of RC as well as PE. Implications for reading education are discussed.  相似文献
