Students with ADHD can benefit from at-home learning in terms of managing their symptoms; however, lockdown restrictions due to the pandemic are having negative impacts on the student population. This study was designed to ascertain how students with ADHD have been impacted by at-home learning under lockdown restrictions. An interpretative phenomenological analysis was conducted using semi-structured interviews from students, parents and teaching staff. These interviews were used to identify three main themes (anxiety caused by at-home learning, change in social interaction and academic impact of at-home learning) that best identified the participants' experiences. The results suggested that whilst supportive home environments helped students with ADHD to better manage their symptoms, social anxiety was a significant problem, and not all schools allowed students with ADHD to take full advantage of at-home learning for their students with ADHD.  相似文献

Abstract

There are several ways of carrying the ball in rugby union, which could influence the speed at which a player can run. We assessed 52 rugby players (34 males, 18 females) during a maximum sprint over 30 m without the ball, with the ball under one arm, and with the ball in both hands. Timing gates were used to measure time over the initial 10 m and the last 20 m. It has previously been reported (Grant et al., 2003 Grant, S. J., Oommen, G., McColl, G., Taylor, J., Watkins, L.Friel, N. 2003. The effects of ball carrying method on sprint speed in rugby union football players. Journal of Sports Sciences, 21: 10091015. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]) that running with the ball produces a slower sprinting speed than running without the ball. We hypothesized that the decrease in speed caused by carrying the ball would become less marked with the experience of the player. The male and female players were each divided into two groups: a “beginner” group that consisted of players in their first or second season and an “experienced” group that was composed of players who had played for more than two seasons. A 2 × 3 mixed-model analysis of variance was used to identify differences (P < 0.01) between the beginner and experienced groups in the three sprinting conditions. The times for the males for the first 10 m sprints without the ball, with the ball under one arm, and with the ball in both hands were 1.87 ± 0.08 s, 1.87 ± 0.08 s, and 1.91 ± 0.1 s for the beginners, and 1.87 ± 0.1, 1.88 ± 0.1 and 1.88 ± 0.12 for the more experienced players respectively. The times for the females for the first 10 m without the ball, with the ball under one arm, and with the ball in both hands were 2.13 ± 0.16 s, 2.19 ± 0.17 s, and 2.20 ± 0.16 s for the beginners, and 2.03 ± 0.12 s, 2.03 ± 0.09 s, and 2.04 ± 0.1 s for the more experienced players respectively. For the last 20 m of the 30-m sprint, there were differences between the different sprint conditions (P < 0.001) but no differences that were attributable to experience (P = 0.297). The times for the males over the last 20 m without the ball, with the ball under one arm, and with the ball in both hands were 2.58 ± 0.19 s, 2.61 ± 0.12 s, and 2.65 ± 0.12 s for the beginners, and 2.59 ± 0.12, 2.62 ± 0.23, and 2.65 ± 0.18 s for the more experienced players respectively. The times for the females over the last 20 m without the ball, with the ball under one arm, and with the ball in both hands were 3.25 ± 0.38 s, 3.35 ± 0.42 s, and 3.40 ± 0.46 s for the beginners, and 3.04 ± 0.32 s, 3.06 ± 0.22 s, and 3.13 ± 0.27 s for the more experienced players respectively. No gender-specific differences were detected. The results of this study suggest that practising sprints while carrying a ball benefits the early phase of sprinting while carrying the ball.  相似文献

Behavior-specific praise (BSP) and other forms of positive feedback and public acknowledgment are underutilized in secondary classrooms. Surprisingly, few studies have evaluated the independent effects of BSP in these settings. Using a multiple baseline design with an embedded A/B/B + C condition sequence, the purpose of the current study was to evaluate the effects of BSP and BSP combined with public posting on the appropriately engaged and disruptive behaviors across 4 secondary classrooms. Results supported a functional relation between BSP alone and improvements in students' appropriately engaged and disruptive behaviors. Combining BSP with public posting, which involved writing students' names on the classroom whiteboard, further increased students' appropriately engaged behaviors but had mixed effects on students' disruptive behaviors. Practical implications, limitations, and directions for future research are discussed.  相似文献

The present study investigated the effects of different intensities of resistance training (RT) on elbow flexion and leg press one-repetition maximum (1RM) and muscle cross-sectional area (CSA). Thirty men volunteered to participate in an RT programme, performed twice a week for 12 weeks. The study employed a within-subject design, in which one leg and arm trained at 20% 1RM (G20) and the contralateral limb was randomly assigned to one of the three conditions: 40% (G40); 60% (G60), and 80% 1RM (G80). The G20 started RT session with three sets to failure. After G20 training, the number of sets was adjusted for the other contralateral limb conditions with volume-matched. CSA and 1RM were assessed at pre, post-6 weeks, and post-12 weeks. There was time effect for CSA for the vastus lateralis (VL) (8.9%, 20.5%, 20.4%, and 19.5%) and elbow flexors (EF) (11.4%, 25.3%, 25.1%, and 25%) in G20, G40, G60, and G80, respectively (p?>?.05). G80 showed higher CSA than G20 for VL (19.5% vs. 8.9%) and EF (25% vs. 11.4%) at post-12 weeks (p?p?相似文献

Discourses promoting the benefits of school autonomy have floated freely internationally since moves in the 1980s to greater devolution in the UK, New Zealand, the USA, Australia and Sweden. The most recent Australian version, Independent Public Schools (IPS), grants school leaders more latitude over aspects of their work. But this autonomy is constrained by technologies of competitive performativity, now the norm across Australian and other school systems. Entrepreneurial policies focused on competition, compliance and improved performance make schools, their leaders and teachers, more responsible to external accountabilities. At the same time, autonomy is creatively exercised by leaders due to public service orientations associated with traditional teacher professionalism. This analysis of two Australian case studies of IPS, a secondary school in Queensland and a primary school in Western Australia, illustrates how school leaders navigate conflicting demands of the audit and performance culture by exercising autonomy according to differing notions of professional responsibility, disrupting and moderating the more inequitable priorities and effects prevalent in many performative systems.  相似文献

Abstract

International Telecommunication Union’s ICT Development Index and related measures of a country’s ICT development maturity suffer from several limitations, including subjective estimation of the weights of individual indicators and sub-indices, use of inappropriate quantitative models, specification bias arising from the exclusion of potential predictors from the estimation models, and a failure to capture the disparities among different groups of countries. To overcome these problems and provide a more reliable measure of ICT development, this study develops the Modified ICT Maturity Level Index using the 2015 data of 166 countries. This index adds affordability, efficiency, and quality to the existing sub-indices of access, use, and skills. Sub-index and indicator weights are determined in an outcome-orientated way using Partial Least Squares Structural Equation Modeling. We find that affordability, quality, and efficiency significantly explain the variation in the level of maturity of ICT development in addition to the previously used dimensions of International Telecommunication Union’s ICT Development Index and modified ICT Development Index (mIDI) developed by Gerpott and Ahmadi, and that their explanatory power differ by a country’s level of economic development. The new index produces significantly different country rankings. This has important implications for ICT policy priorities and provides a measure of ICT development maturity less prone to the innocent or intentional distortion of such policy priorities.  相似文献
