The presentation of image in Charles H. Percy's whistle‐stop tour of 1966

The Whistle‐Stop Campaign of Charles Percy appeared to have a significant effect upon the outcome of his senatorial race with Paul Douglas. This study explores the development and execution of the whistle‐stop campaign and assesses its probable effect on the election.     

Situational interest,computer self‐efficacy and self‐regulation: Their impact on student engagement in distance education

This study investigates possible relationships among motivational and learning variables (interest, self‐efficacy and self‐regulation) and three types of student engagement (behavioural engagement, emotional engagement and cognitive engagement) in a distance education setting. Participants were 203 students enrolled in online classes in the fall semester of 2008 in the Schools of Gerontology and Engineering at a large research university in the south‐western USA, who completed an online survey assessing their levels of situational interest, computer self‐efficacy, self‐regulation and engagement in distance education. Situational interest and self‐regulation were found to be significantly correlated with three types of engagement (behavioural, emotional and cognitive), while computer self‐efficacy did not appear to be associated with any of those engagement variables. Results suggested that online activities and tools such as multimedia and discussion boards may increase emotional engagement in online learning, although they do not necessarily increase behavioural or cognitive engagement, that educators should identify students who are taking online courses for the first time and provide necessary technical help to increase their emotional engagement, and that it is important for educators to offer students strategies for increasing their self‐regulation in distance education environments.     

Precision Knowledge of Results and Motor Performance: Relationship to Age

In motor skill performance and retention the complexity of knowledge of results should interact with the child's processing rate. This rate has been demonstrated to increase with age. Two experiments were designed to assess this hypothesis. In Experiment 1, 30 7-year-old and 30 10-year-old boys were randomly assigned within age level to three knowledge of results (KR) conditions: no KR, general KR, and precise KR. Performance was assessed on a vertical positioning task at two angles, 60° and 100°, for 10 performance trials. The preciseness of KR interacted with age and the degree of the angle, indicating that at the more difficult angle (60°) preciseness may have been detrimental to the performance of the 7-year-olds but beneficial to the 10-year-olds. At the easier angle (100°), precise KR improved performance for both age groups. In Experiment 2, 27 second-grade and 27 fourth-grade children were randomly assigned within age groups to the same three levels of KR preciseness. A horizontal curvilinear positioning task was used as the motor task and subjects were given 40 acquisition and 19 KR withdrawal trials. Results suggested that while KR was better than no KR during learning, the level of KR preciseness was of minor importance. However, the preciseness of KR during acquisition was of considerable value after KR was withdrawn (retention phase). The older children were able to use more precise KR to form a perceptual trace more resistant to forgetting, while the younger children were unable to use the additional information contained in precise KR.     

Reaction Time and Anticipation Time: Effects of Development

Abstract

The developmental nature of reaction time (RT) and anticipation timing (AT) performance, as well as the relationship between them, was investigated using 15 male and 15 female subjects at each of five age levels—7, 9, 11, 13, and 20 yrs. Each subject was given 40 trials for both RT and AT performance with task order counterbalanced. Results indicated that as age increased RT decreased, with males having more rapid RT than females. The two younger age groups differed from the three older groups on AT performance. RT was significantly correlated with AT (|CE| measure) for the 7, 9, and 11 yr old males but not in any other age by gender condition. Apparently neither young males nor young females have a good motor plan in memory to control AT performance. However, the more rapid RT (and thus better response initiation) of the males allows better AT performance at the younger ages. Beginning about 10–11 yrs of age, better motor plans are developed in children's memory system, leading to less reliance on rapid RT for good AT performance, and thus the correlation between RT and AT performance is not present.     

Gender Differences in Children's Throwing Performance: Biology and Environment

Abstract

This study evaluated the influence of biological and environmental variables on the differences between the throwing performance of 5-year-old girls and boys. A total of 100 children (48 girls, 52 boys) were tested on throwing for distance and rated on two components of throwing form—trunk rotation, and foot action. Children were evaluated on eight biological characteristics—height, weight, body mass index, ponderal index, sum of four skinfolds, body diameters, arm and leg girths, and somatotypes—and four environmental characteristics—older brother, older sister, presence of adult male, and playing with older children. Results indicated that boys threw farther than girls and exhibited more mature form. Boys had greater joint diameters than girls, a smaller sum of four skinfolds, and more estimated arm muscle. Boys were more likely to play regularly with older children. Girls' throwing performance was only 57% that of boys, but when throwing was adjusted for a linear composite of biological variables, girls' throwing performance increased to 69% of boys'. Thus, while the differences in most motor performance tasks between boys and girls prior to puberty have been attributed to environmental factors, some of the differences in throwing performance appears to reflect biological characteristics, even as early as 5 years of age.     

The Use of Meta-Analysis in Exercise and Sport: A Tutorial

Abstract

Meta-analysis is a set of procedures used to quantify, integrate, and analyze the findings of a large number of research studies. It offers the advantage of quantifying effects from individual studies in addition to specifying the procedures the authors followed when reviewing the literature. Although meta-analysis has been demonstrated as a useful technique in exercise and sport research, and new and more appropriate statistical techniques for use in meta-analysis have been developed, these procedures are not widely used. This tutorial describes these advances and provides an example of their application to data from gender differences in throwing velocity during childhood and adolescence.     

Children's Experiences of Fun and Enjoyment During a Season of Sport Education

This paper reports on a 16-week sport education (SE) unit with just over 70 year 5 students (M age = 10.04 years) in one United Kingdom school during the spring and summer terms and discusses students' SE experiences. Student interviews were conducted throughout the season and a questionnaire on different motivation aspects was administered prior to and before completing the SE season. We report and examine the data in relation to hypothesized influences on fun and enjoyment, including being part of a team, autonomy, and improving game play. The principal reasons SE may be more enjoyable than previous physical education lessons include the greater opportunities for autonomy, affiliation, and competition, plus perceived learning.     

The impact of social media on informal learning in museums

This paper posits that social networking can take a central role in learning in informal environments such as museums, libraries and galleries. It argues that social media offers young people agency previously unavailable in informal learning environments in order to explore complex responses to and participation with cultural content. The paper will consider transformations in digital literacy and the processes by which young learners can connect with knowledge in informal learning environments to become active cultural participants.
