Abstract

Previous research has shown that experts exhibit superior response selection and skill execution during performance in youth sport. The purpose of this study was to examine differences in cognitive and skill execution components of game performance in young baseball players (N = 159) with, varying levels of expertise. Three levels of expertise (low-, average-, and high-skilled players) were identified at each age level (7, 8, 9, and 10 years of age). Game performance was videotaped, and measures of skill execution (throwing accuracy, throwing force, fielding, catching, batting average, and batting contact) and cognitive components (positioning, decisions) were developed from observational analysis. The results indicated that baseball skill execution during game play maximally discriminated expertise levels.  相似文献

This qualitative case study used tenets of critical race theory and a single focus group and individual interviews with 4 African American football athletes at a predominantly White institution of higher education (PWIHE) in an effort to bring the voices of this marginalized group into the dialogue on issues concerning institutional integrity in college sport. Institutional integrity involves an athletic program's actual commitment to the educational interests of college athletes as expressed through their structures, functions, and activities. Three themes emerged from the data: (a) there is a need for more African American role models in leadership positions within the athletic departments of these PWIHE; (b) there is a need for more financial support for athletes; and (c) African American athletes should be given a platform to voice concerns. These findings have implications for those educational stakeholders and researchers who are genuinely concerned with institutional integrity in college sport.  相似文献

Abstract

Because manipulations of knowledge of results (KR) are critical to motor learning, researchers have attempted to establish an optimal length for summary KR. Experiment 1 of the present study investigated the option that optimal summary length may be dependent on a subject's task-related experience. Participants in a summary 1, 5, or 15 condition practiced a simple striking task for one session on three consecutive days with each day followed by a 24-hour no KR retention test. The retention test results indicated that optimal summary length is dependent on task-related experience. Experiment 2 investigated the nature of the relationship between task-related experience and complexity and optimal summary length (summary 1, 5, or 15). Again, striking tasks (simple and complex) were used. There was one practice session with either a simple or complex striking task for either novice or experienced performers, followed by a 24-hour no KR retention test. Data from the two experiments suggest that task complexity and performer experience interact in determining optimal summary length.  相似文献

Abstract

Previous research on the development of jumping has indicated that the coordination of the jump is stable from its inception, but that individual differences lie in the control of the task. The purpose of this study was to examine control in the vertical jump as performed by novice jumpers. Two groups of children who varied in their ability to regulate the takeoff angle were compared on measures of coordination and control. The children's groups were also compared to a group of skilled adults. Both children's groups demonstrated temporal coordination patterns comparable to the adult pattern, though the children were distinguished from the adults on selected spatial (control) measures. The results indicate that a mature pattern of coordination for the jump exists at the earliest stages of the behavior's appearance in the movement repertoire. The novice, however, lacks the ability to precisely control, or tune, the movement to task demands.  相似文献

This article discusses the interaction of attachment processes and stages of social work student development within the field supervisory relationship and suggests ways supervisors can modify interactions with students. Attachment theory and research provide a framework for understanding innate capacities of students and the relational dynamics of supervision. Developmental stages of learning explain how students mature and the supervisory relationship changes over time. Scenarios from the beginning and ending of the field practicum are used to illustrate how to differentiate attachment traits from developmental states in assessing student affect and behavior. Recommendations are made for training and future supervision research.  相似文献

The article describes and evaluates an innovative experiment in education and training of social workers at an academic learning center, which was established by the Hebrew University's School of Social Work and Social Welfare in a neighborhood of Jerusalem. The project focused on strengthening the link between theory, research, and practice. Participants were exposed to advanced theories and macropractice seminars, and gained practical experience as well as tools and technologies for coping with the social problems faced by Jerusalem neighborhoods. In that process, they became aware of the difficulties involved in initiating programs and in establishing coalitions with neighborhood institutions, residents, and other constituencies. The article deals with the achievements of the learning center, as well as with the difficulties and dilemmas encountered in the effort to sustain collaboration between the university and the community. In addition, issues related to supervision of students specializing in community work and practice, and implications for social work education are presented and discussed.  相似文献

This study evaluated the impact of a distance education program to meet the practice learning needs of first‐year doctoral students. The program, a six‐session case‐based telephonic seminar, was taught to 19 first‐year doctoral students. Evaluation of the program included self‐report quantitative and qualitative data gathered pre‐ and postseminar, as well as qualitative data gathered three months postseminar. Quantitative and qualitative analysis revealed increased reports of practice competencies by the conclusion of the seminar. Analysis also illustrated the importance of continued evaluation given the small sample size and pilot nature of this unique distance education program.  相似文献

This paper examines the use of analogies in statistics instruction. Much has been written about the difficulty social work students have with statistics. To address this concern, Glisson and Fischer (1987) called for the use of analogies. Understanding of analogical problem solving has surged in the last few decades with the integration of psychology and artificial intelligence. However, the application of analogies has not been examined further in social work literature. This work uses cognitive science to discuss the five steps of analogical problem solving. Implications for statistics instruction in social work are discussed with examples.  相似文献

Since 1959, Cuba has undergone a series of political changes, and since 1989, Cuba has had to invent, evolve, and implement a new system of food production that provides lessons from which others can learn. Many of the changes since 1989 caused shocks to the food-security system. As a result many institutions and individuals had to absorb the realities of a food production and distribution system faced with major disruption. These shocks led to adjustments and adaptations necessary to ensure a secure food supply for the 11 million inhabitants of Cuba. This article focuses on adjustments and adaptations made in the extension domain within Cuba's unique agricultural knowledge and information system.  相似文献
