The relationship between physical activity and self-efficacy in children with disabilities

Abstract

The main purpose of this study is to investigate whether self-efficacy in children with disabilities could be strengthened through targeted and adapted physical activities led by specially educated leaders. Children and Youth Physical Self-Perception Profile (CY-PSPP) scale were used. The study includes 45 children of 8–14 years of age with different types of impairments. The children participated in training sessions twice a week and tried out 13 different physical activities during eight months. The median in this study of total self-efficacy was 104 points, which can be compared to median points varying between 100 and 107 in previous studies based on children without disabilities. Furthermore, there was a statistically significant increase of the means in four out of six different domains of self-efficacy before and after the study was carried out. Key findings indicated that this model is successful in strengthening the children’s self-efficacy and that their perceived self-efficacy was equal to that of children without disabilities.     

The relationship between functional potential and field performance in elite female wheelchair basketball players

The functional classification system for wheelchair basketball is based on an analysis of the players' functional resources through field-testing and game observation. Under this system, players are assigned a score of 1 to 4.5. The aim of this study was to determine if the wheelchair basketball player classification system reflects the existing differences in performance of elite female players. During the World Championship for Wheelchair Basketball in Sydney 1998, eight teams were videotaped for three 40-min games for a total of 120 min per team. Fifty-nine female players (Class I [1 and 1.5 points] n=12; Class II [2 and 2.5 points] n=20; Class III [3 and 3.5 points] n=13; Class IV [4 and 4.5 points] n=14) were retained for a detailed performance analysis by means of the Comprehensive Basketball Grading System (CBGS). Two-way analysis of variance showed high point players to perform better compared with low point players for the majority of variables determining the quality of game performance. A lack of significant differences between two adjacent classes was explained on the basis of the methodological approach, the class-position relationship in this sample, and the performance level of women's wheelchair basketball. We conclude that the performance of elite female wheelchair basketball players is dependent on functional ability.     

Time needed to change the isometric force production of a response

This study investigated the time needed to change a motor program that specified the elbow flexor muscles to gradually increase the isometric force production from 15% to 75% of one's maximum voluntary contraction (MVC). A double-stimulation paradigm was used with the restriction that subjects (N = 12) be at 15% of their MVC before the presentation of the first stimulus. Subjects reacted to the first stimulus (randomly presented) by gradually increasing their isometric force from 15% to 75% of their MVC and then reacted to the second stimulus by altering the force production in one of four ways: (a) increasing the force to the 75% level rapidly instead of gradually, (b) discontinuing the increase and maintaining the level of force attained, (c) discontinuing all force production, or (d) reversing the direction of force so that it is produced by the elbow extensors. The data revealed that more time was needed to increase the force rapidly than to perform any of the other three conditions.     

Development of the Biology Card Sorting Task to Measure Conceptual Expertise in Biology

There are widespread aspirations to focus undergraduate biology education on teaching students to think conceptually like biologists; however, there is a dearth of assessment tools designed to measure progress from novice to expert biological conceptual thinking. We present the development of a novel assessment tool, the Biology Card Sorting Task, designed to probe how individuals organize their conceptual knowledge of biology. While modeled on tasks from cognitive psychology, this task is unique in its design to test two hypothesized conceptual frameworks for the organization of biological knowledge: 1) a surface feature organization focused on organism type and 2) a deep feature organization focused on fundamental biological concepts. In this initial investigation of the Biology Card Sorting Task, each of six analytical measures showed statistically significant differences when used to compare the card sorting results of putative biological experts (biology faculty) and novices (non–biology major undergraduates). Consistently, biology faculty appeared to sort based on hypothesized deep features, while non–biology majors appeared to sort based on either surface features or nonhypothesized organizational frameworks. Results suggest that this novel task is robust in distinguishing populations of biology experts and biology novices and may be an adaptable tool for tracking emerging biology conceptual expertise.     

Group Behavior and Learning in Electronic Forums: A Sociotechnical Approach

The term community is widely and often uncritically used to characterize groupings of people who meet in electronic forums (e-forums). The research reported here shows how the casual use of the term community to characterize these groups can actually undermine their transformation into forms of social organization that are justifiably characterized as communities. This article examines how transforming a group into a community is a major accomplishment that requires special processes and practices. Primary data come from a particular project, the Inquiry Learning Forum (ILF), that aimed to develop "communities of practice" (CoPs) among high school science and mathematics teachers through an elaborate dedicated web site. We examine participants' behaviors in some of the differently structured forums within the ILF web site. While the project's developers expected CoPs to develop autonomously, there was no evidence of CoP formation in open public online forums. The article contrasts two approaches to building online communities that differ sharply: "IT-led community development" and "IT-supported community development." The experience of the ILF project shows that IT-led strategies community development strategies are much more difficult to make workable than are the "IT-supported" strategies.     

Identity(ies) Explored: How Journalists’ Self-conceptions Influence Small-town News

Existing literature on community journalism suggests it is worthwhile to theoretically and conceptually examine journalists in small towns. These reporters and editors always wear multiple hats, including news worker, community member, and booster. Therefore, drawing on newsroom observations and interviews, and applying the interpretive lenses of sociology and identity theory, this study examines the self-perceived identities of weekly newspaper news workers, and how those identities influence their news production. Findings across three organizations show that for these journalists, professional identity is intertwined with personal identity as a church member or baseball coach. Simply put, these journalists see themselves as members of the community that their newspaper covers. Their interactions with friends and neighbors are also interactions with sources – and with advertisers. This sense of personal connection further serves as a key motivation to produce meaningful news for their communities, which the author suggests has served as a safeguard to declines in readership for many small-town weekly newspapers.
