Learning activities and interactive videodisc: an exploratory study

This article reports the findings of a small-scale study on pupil use of interactive videodisc. The types of learning activity in which the groups of pupils engaged are identified and the proportion of time spent on each is shown. Patterns in the data are analysed by ability of the pupil group and by the number of sessions in which the videodisc had been used. The discussion focuses on two interesting results: the high proportion of time spent on reading, watching and listening; and the greater statistical differences within groups than between groups of pupils.     

Exploring inclusive practices in primary schools: focusing on children’s voices

This paper reports a small-scale research project which took place in one primary school in the north-east of England. The study aimed to listen to children’s views about how the practices of teachers helped and/or hindered their sense of inclusion in classrooms. Inclusion was understood here in a broad sense rather than specifically relating to children with special educational needs. Participatory research tools were used as part of group interviews with children from three different year groups. Even though the children were mostly happy with their school experience, it was noticeable that there were some areas for concern for some children that related to four interconnecting themes: unfairness, shouting, loneliness and seating plans. All of these themes seemed to be connected with children’s interpersonal relationships – with teachers and with each other – and can be seen as crucial in terms of understanding inclusion in schools and further developing existing practices.     

Using teacher ratings of social behavior to differentiate gifted from non‐gifted students

This study investigated the effectiveness of teacher ratings of student social behavior in differentiating a group of 81 elementary‐age gifted students from a control group of 81 age and gender matched non‐gifted students. The School Social Behavior Scales, a recently developed set of rating scales that assesses both social competence and antisocial behavior, was used for the ratings. Gifted students were rated as having significantly higher levels of social competence and lower levels of antisocial behavior than the comparison group, and the individual scores of the gifted students were significantly skewed in the direction of better social‐behavioral adjustment. The findings also indicated the presence of a small subset of gifted students who appeared to have extremely poor social competence and high levels of problem behaviors. The results are compared to previous research on the psychosocial development of gifted children, and important areas for future research on this topic are recommended.     

Examining charter student achievement effects across seven states

Since their inception, charter schools have been a lighting rod for controversy, with much of the debate revolving around their effectiveness in improving student achievement. Previous research has shown mixed results for student achievement; this could be the consequence of different policy environments or varying methodological approaches with differing assumptions across studies. In our analysis, we discuss these approaches and their assumptions and estimate charter school achievement effects using a consistent methodology across seven locations.     

Physical activity and lipidomics in a population at high risk of type 2 diabetes mellitus

ABSTRACT

The aim was to investigate how measurements of the lipidome differ according to the level and intensity of physical activity in a population at high risk of type 2 diabetes (T2DM). A targeted metabolomics platform provided quantitative molecular data on lipid species. Linear regression examined the associations between plasma lipid concentrations, particle size and time spent in objectively measured physical activity intensity domains, in increments of 500 counts per minute (cpm) (up to >4500 cpm (~>5.6METs)). Results are presented as % difference in the concentration (lower/higher) or particle size (smaller/larger) per 10 min of activity within each intensity. Five hundred and nine participants were included. Time spent in the lowest physical activity intensity domain (<500 cpm) was unfavourably associated with VLDL (2%), HDL (?2%) and Apolipoprotein A-1 particle concentrations (?2%) and HDL diameter (?2%). Conversely, time spent in intensities ≥1000 cpm were favourably associated with HDL subclass concentrations; with stronger associations seen at moderate intensities (2000-3999 cpm (~4.5METs)). For Apolipoprotein-B concentration and VLDL particle concentration and size, a negative association was consistently observed at the highest physical activity intensity only. If these associations are causal, HDL subclasses appear sensitive to light-intensities whereas only the high category of physical activity intensity was consistently associated with VLDL subclasses.     

Validity of a Tympanic Thermometer and Thermal Imaging Camera for Measuring Core and Skin Temperature during Exercise in the Heat

ABSTRACT

This study compared criterion to minimally invasive, practical measures of core (T_c) and skin (T_sk) temperature during 30 min of moderate-intensity cycle exercise in a heat chamber (35°C, 60% rH). T_c was monitored using a core temperature pill (T_c(Pill)) and tympanic thermometer (T_c(Tymp)) during rest, exercise, and recovery in 15 participants. T_sk was monitored using hard-wired skin thermistors attached to a data logger (T_sk(T)) and a thermal imaging camera (T_sk(IR)) in 11 participants. T_c measurement resulted in no significant difference (p > 0.05), a mean bias of 0.1°C, coefficient of variation (CV%) of 1.0%, and correlation of r = 0.74 between devices. T_sk measurement resulted in a significant difference (p = 0.01), a mean bias of 0.6°C, CV% of 2.3%, and correlation of r = 0.61 between devices. T_c(Tymp) demonstrated acceptable agreement with T_c(Pill); however, caution is advised when using T_sk(IR) to give accurate measures of T_sk during exercise.     

Quality of Life Assessment for Physical Activity and Health Promotion: Further Psychometrics and Comparison of Measures

Despite the clear relationship between physical activity and quality of life, few sound, relevant quality of life measures exist. Gill and colleagues developed a 32-item quality of life survey, and provided initial psychometric evidence. This study further examined that quality of life survey in comparison with the widely used short form (SF-36) health survey. Participants (n = 446) completed the quality of life survey, short form (36) health survey, World Health Organization quality of life measure, satisfaction with life scale, and the Godin physical activity measure. All quality of life survey scales (emotional, social, spiritual, physical, activities of daily living, cognitive, integrated) were internally consistent (alpha .79–.95) and test–retest correlations ranged from .68 to .82. The SF-36 had similar internal consistency, slightly lower test–retest correlations, and weaker relationships with satisfaction with life scale. Quality of life survey scales correlated with matching SF-36 and World Health Organization quality of life measure subscales supporting convergent validity. The quality of life survey reflects positive health models better than the SF-36, and is more appropriate for research and programs that focus on physical activity and health promotion.
