Use and relationships among effective practices in co-taught inclusive high school classrooms

Opportunities to respond (OTR) and specific praise are two practices that may be particularly beneficial to students learning in secondary inclusive classrooms. Yet, there is relatively little research on effective inclusion practices involving secondary students with learning disabilities (LD) or studies at the secondary level. This study sought to extend the existing research by evaluating the relationship between rates of OTR and specific praise in co-taught high school core classrooms on student on-task behaviour and class engagement. This study was part of a larger study conducted during the 2010–2011 school year. First, core academic classrooms were observed and data were collected on OTR, praise, and student behaviour. OTR information was collected using an audio recording device. Class audio recordings were divided into 15-minute intervals of whole group instruction and coded for OTR, specific praise, and non-specific praise. Observation data on student behaviour and class engagement that corresponded with each 15-minute interval were identified. Results indicate low levels of teacher use of OTR and praise statements and few significant relationships found between the variables of interest. Implications for practice and future research directions are also presented.     

Academic discipline and risk perception of technologies: An empirical study

This article brings together two areas of research: studies on risk perception of technologies and studies on vocational/career choice. This is an important link since decisions concerning technologies are influenced by decision makers’ risk perceptions and these in turn may be related to educational and career paths.We analyze students of different academic disciplines with regard to their risk perception of four technologies. The aim is to find out whether there is a relationship between area of study (as a precursor of vocational and career choice) and risk perception of technologies regarding health, environment and society. The four technologies under study are renewable energies, genetic engineering, nanotechnology and information and communication technologies (ICT). Key results are: irrespective of academic discipline risk of genetic engineering on average is rated highest and renewable energies lowest. This holds for all the risks studied (environmental, health, societal risks). On average, students from different academic disciplines differ in their risk perception. Factor analyses show that common dimensions of risk are the technologies and not the kind of risk. Regression analyses show that the variables influencing perceived risks vary between the technological fields.     

Effect of a health-improvement pilot programme for older adults delivered by a professional football club: the Burton Albion case study

Older adults are a priority within policy designed to facilitate healthy lifestyles through physical activities. Golden Goal is a pilot programme of physical activity-led health improvement for older adults, 55?years and older. Activities were delivered at Burton Albion Football Club. Sessions involved weekly moderate to vigorous intensity exercise sessions including exer-gaming (exercise-orientated video-games), indoor bowls, cricket, new age curling, walking football, and traditional board games and skittles. Secondary analysis of data collected through the original programme evaluation of Golden Goal investigated the impact of the intervention on participants. Older adults completed self-reports for demographics, health screening/complications and quality of life. Attendees, n?=?23 males (42.6%) and n?=?31 females (57.4%) with a mean age of 69.38 (±5.87) (n?=?40), ranging from 55–85?years took part. The mean attendance was 7.73 (±3.12) sessions for all participants, (n?=?51). Older adults with two or more health complications (n?=?22, 42.3%) attended fewer sessions on average (6.91?±?3.322) compared to those reporting less than two health complications (8.65?±?2.694). Self-rated health was higher for women (87.32?±?9.573) vs. men (80.16?±?18.557), although this was not statistically significant (U?=?223.500, p?=?0.350). Results support the potential of football-led health interventions for recruiting older adults, including those reporting health problems.     

Home advantage in judo: A study of the world ranking list

Abstract

In 2009, the International Judo Federation established a ranking system (RS) to classify athletes and to distribute the competitor quotas of the Olympic Games. However, the RS does not consider the home advantage. This issue has not been studied in judo, and its implications for the RS have not been determined. The objective was to verify the home advantage in judo in terms of winning a medal or the number of matches won. Therefore, 25 competitions that computed points for the RS in 2009 were analysed. Logistic regression analysis and the Poisson generalised linear model were used for the analyses, which included the relative quality of the athletes. The sample was composed only of athletes who had competed both at home and away. The odds ratio for winning medals was higher for athletes who competed at home for both males and females. The association between the number of matches won and competing at home was significant only for the male athletes. The home advantage was observed in the competitions that used the judo RS. Thus, it is likely that athletes from countries that host competitions using the RS have an advantage in terms of obtaining their Olympic classification.     

The physiological load imposed on basketball players during competition

In this study, the intensities of activity and movement patterns during men's basketball were investigated by videoing the movements and monitoring the heart rate and blood lactate responses of eight elite players during competition. The results are expressed according to ‘live time’, which is actual playing time, and ‘total time’, which includes live time as well as all stoppages in play. The mean (± s.d.) frequency of all activities was 997 ± 183, with a change in movement category every 2.0 s. A mean total of 105 ± 52 high‐intensity runs (mean duration 1.7 s) was recorded for each game, resulting in one high‐intensity run every 21 s during live time. Sixty percent of live time was spent engaged in low‐intensity activity, while 15% was spent in high‐intensity activity. The mean heart rate (HR) during live time was 169 ± 9 beats min^‐l (89 ± 2% peak HR attained during laboratory testing); 75% of live time was spent with a HR response of greater than 85% peak HR. The mean blood lactate concentration was 6.8 ± 2.8 mM, indicating the involvement of glycolysis in the energy demands of basketball. It is concluded that the physiological requirements of men's basketball are high, placing considerable demands on the cardiovascular and metabolic capacities of players.

‘Observation has set in’: comparing students and peers as reviewers of teaching

Peer review is a powerful method to enhance teaching in higher education. Peers, however, may not be the most relevant people in evaluating teaching success; as the most important stakeholders in learning, students’ evaluations need to be heard. Whilst some efforts to capture ‘the student voice’ are simplistic and may foster consumerist approaches, adopting ‘radical collegiality’ towards students may provide the benefits of peer review whilst avoiding some of its disadvantages. Here we describe the Students as Colleagues project, which trained student volunteers as evaluators of teaching. To assess the ability of students to provide useful reviews, we compared their evaluative feedback with that from academic peers, using a paired design and qualitative and quantitative data. Students gave significantly more positive comments, and just as many negative and directive comments, as academic peers. Student colleagues emphasised the positive personal (rather than professional) capacities of their reviewees, encouraged expressed vulnerability and drew on their broad experiences as students rather than from professional perspectives. Participation changed how students saw their abilities and helped ‘humanise’ both the reviewees and the university as a whole. Our results and standpoint theory suggest that students’ evaluative feedback is the most valuable perspective to inform teaching enhancement.     

Sleep Disturbance and Expressive Language Development in Preschool‐Age Children With Down Syndrome

Recent evidence has suggested that sleep may facilitate language learning. This study examined variation in language ability in 29 toddlers with Down syndrome (DS) in relation to levels of sleep disruption. Toddlers with DS and poor sleep (66%, n = 19) showed greater deficits on parent‐reported and objective measures of language, including vocabulary and syntax. Correlations between sleep and language were found in groups with equivalent medical and social backgrounds and after control for relevant behavioral comorbidities, including autism symptoms. These results emphasize the important role of quality sleep in all children's expressive language development, and may help increase our understanding of the etiology of language deficits in developmental disorders, potentially leading to new treatment approaches.     

Kinematic effects of a short-term fatigue protocol on punt-kicking performance

The punt kick is a fundamental skill used in several team sports; however, there has been a lack of research on how fatigue affects its technique. The purpose of this study was to determine the effects of short-term fatigue on punt-kicking performance. Eight elite and sub-elite Australian Football players performed maximal drop punt kicks on their preferred leg prior to, during and after a match-specific fatigue protocol. Optotrak Certus collected kinematic data from kick foot toe-off until ball contact. Repeated-measures analysis of variance showed a significant increase in 20 m sprint times after each short-term protocol, indicating fatigue. Foot speed did not significantly change with fatigue; however, increases in the range of motion at the pelvis and kicking thigh, along with increases in kicking thigh angular velocity, occurred. For the support leg, maximum knee flexion angular velocity increased while there was greater flexion found at the knee and hip, and greater range of motion at the knee. Players are able to make kinematic adaptations in order to maintain foot speed while punting for maximal distance after short-term efforts.
