Teaching and learning by videoconferencing at the University of Ulster

The Open University has developed an array of tutorial and advisory services for its students over 16 years. These have been reviewed regularly for their academic appropriateness and effectiveness. More recently, urgent reductions in services have taken place, in response to financial restraints. During 1985, Mary Thorpe and colleagues in the Student Research Centre, the Institute of Educational Technology conducted in‐depth interviews with students and staff to explore their perceptions of studying with the Open University.     

Children's views of Teaching Assistants in primary schools

This study reports primary children's perceptions of the role of the Teaching Assistant (TA) in three state primary schools in South West England. Through the use of a questionnaire and semi-structured interviews, an exploration was made of how children view TAs, who are commonly found delivering the curriculum alongside the teacher in the classroom. A simple questionnaire was completed by 419 junior children and 86 infant and junior pupils were interviewed, giving children a ‘voice’ about an environment which they inhabit for a substantial proportion of their lives. The results show that children between the ages of 5–11 perceive the role of the TA to be of value and their work to be useful and helpful. Their accounts of the TAs' work in general and in relation to themselves, in particular, were clear and insightful. They distinguish between teacher and TA in terms of training, vocation and responsibility. Most children consider themselves to be confident and willing to ask for help but a significant minority reported that they preferred not to ask for help. The implications of the findings for further research on children's views and for educational practice are discussed.     

Motivation in the Junior Years: International perspectives on children's attitudes,expectations and behaviour and their relationship to educational achievement

This paper reports findings from a large-scale international investigation of a number of factors that are considered to impact upon educational motivation and achievement. Following on from an earlier investigation of adolescent attitudes, the present study involved a detailed survey of nearly 3,000 children, aged 9-10 from districts in England, Russia and the USA, together with teacher reports and the employment of a test of basic mathematical computation. The Russian sample scored significantly more highly on the computation test and showed no large tail of underachievers, as was the case with the other groups. Findings from the survey indicate that many of the differences found in the earlier adolescent study are equally true for younger children. The Russian children were less likely to express satisfaction with their abilities or workrates, were more positive towards school, more likely to see education as intrinsically valuable and tended to spend significantly more time on homework tasks. Data obtained also suggest that the Russian sample experienced classrooms with far less disruption and stronger prosocial peer influences than did the English and American children. Teacher understandings of what is considered to be acceptable behaviour appeared to differ, however. The paper notes that the Western samples overestimated their teachers' views of their ability while the Russian children provided underestimates. Possible reasons for, and implications of, these differential teacher messages are discussed. The paper concludes by examining the implications of the findings from the study for increasing motivation and achievement in countries with very different sociocultural contexts.     

Ethical dilemmas and practical problems for the practitioner researcher

This paper explores the ethical dilemmas and problems encountered when undertaking an action research study in my own school. The study was designed to evaluate a contentious part of a new midwifery programme as it was being implemented. A range of potentially problematic issues are discussed from the practitioner researcher perspective. Some of these problems were anticipated but others had not been addressed and had to be responded to as they arose, More careful thought at the planning stage about the potential effects on others, as well as action-in-reflection are presented as important considerations for other practitioners contemplating action research in their own place of work.     

American Association for Health,Physical Education,and Recreation

ABSTRACT

Purpose: The purpose of this study was to identify whether post-resistance exercise (REx) blood flow restriction (BFR) can elicit a similar acute training stimulus to that offered by either heavy REx or traditional low-load BFR REx. Method: Ten men completed trials with 30% one-repetition maximum (1RM) for 5 sets of 15 repetitions without BFR (30%), with BFR during exercise (30% RD), and with postexercise BFR (30% RP) and at 75% 1RM for 3 sets of 10 repetitions. Lactate and cortisol were measured before and up to 60 min after exercise. Thigh circumference, ratings of perceived exertion (RPE), and pain were measured before and after exercise. Surface electromyography was measured during exercise. Results: All conditions had a large effect (effect size [ES] > 0.8) on lactate, with the largest effects observed with the 75% condition; no differences were observed between the 30% conditions. All conditions had a moderate effect (ES > 0.25 ≤ 0.4) on increasing thigh circumference. This effect was maintained (ES = 0.35) with the application of BFR after REx (30% RP). Change in RPE, from the first to last set, was significantly greater with 30% RD compared with other conditions (all p < .05). Electromyography amplitude was higher and percentage change was greater for the 75% condition compared with the other conditions (both p < .05). Conclusions: The application of BFR immediately post-REx altered several of the responses associated with REx that is aimed at inducing muscular hypertrophy. Additionally, these changes occurred with less pain and perceived exertion suggesting that this form of REx may offer an alternative, tolerable method of REx.     

Food Safety Education Using Music Parodies

ABSTRACT:  Musical parodies of contemporary songs with their lyrics altered to address current food safety issues were incorporated into a variety of food safety educational programs and the effectiveness of the music was evaluated by semiquantitative and qualitative measures. Audiences receiving the music-enriched curricula included school foodservice supervisors, school foodservice managers, culinary arts instructors, culinary arts students, Family and Consumer Sciences teachers, and youth aged 8 to 12 y and studies were conducted in South Carolina, North Carolina, and Delaware. Among school foodservice supervisors, school foodservice managers, and culinary arts students, most participants were able to recall the main points of each song that was introduced in the curriculum. The culinary arts students were less likely to recall the main points of each song than were the other 2 groups, possibly because of the lack of prior knowledge of food safety practices as well as a lack of preference for the style of songs used. Family and Consumer Sciences teachers were enthusiastic about the use of the music but also identified potential barriers to the successful use of the music, due to the potential lack of appropriate audiovisual equipment, a lack of skills in using such equipment, and time constraints for the use of music in curricula due to the strong emphasis on end of year testing. Participants in the summer youth groups demonstrated significant increases between pre- and posttest examinations of safe food handling behaviors and most were able to quote lines or phrases from the songs.     

Recovering Predictor–Criterion Relations Using Covariate-Informed Factor Score Estimates

Although it is currently best practice to directly model latent factors whenever feasible, there remain many situations in which this approach is not tractable. Recent advances in covariate-informed factor score estimation can be used to provide manifest scores that are used in second-stage analysis, but these are currently understudied. Here we extend our prior work on factor score recovery to examine the use of factor score estimates as predictors both in the presence and absence of the same covariates that were used in score estimation. Results show that whereas the relation between the factor score estimates and the criterion are typically well recovered, substantial bias and increased variability is evident in the covariate effects themselves. Importantly, using covariate-informed factor score estimates substantially, and often wholly, mitigates these biases. We conclude with implications for future research and recommendations for the use of factor score estimates in practice.
