CILT2000: Community Tools     

Gray  James H. 《Journal of Science Education and Technology》2002,11(3):297-299

Community tools are technologies designed to foster social processes of learning through active inquiry, project-based learning, and related collaborative pedagogical approaches. Current research and development in this field are moving from generic tool design towards the development of sociotechnical systems that address learning in relation to specific domains of knowledge or activity and social issues such as equitable access to learning opportunities.  相似文献   

Academic progress of children who attended a preschool for abused children: a follow-up of the keepsafe project     

Gray J  Nielsen DR  Wood LE  Andresen M  Dolce K 《Child abuse & neglect》2000,24(1):25-32

OBJECTIVE: This study was undertaken to assess academic progress of children 1 to 5 years after graduating from the C. Henry Kempe Center's Therapeutic Preschool Day Treatment Program. METHOD: Information was gathered through chart review; telephone surveys of care providers, relatives, and social service workers; as well questionnaires on all children who attended the therapeutic preschool day treatment program between 1984 and 1989, including the 24 children reported on by Oates, Gray, Schweitzer, Kempe, and Harmon, 1995. RESULTS: Classroom placement was determined for 27 of the 44 graduates (61.4%), 14 of whom (51.9%) were in a regular classroom, 10 (37.0%) in special education, two (7.4%) in residential treatment, and one (3.7%) was receiving home schooling. Twenty-two of the 27 children (81.5%) improved or remained in the same grade and type of classroom as they had been staffed into at the time of their graduation from the preschool day treatment program. Factors thought to affect stability of classroom placement were studied, of which frequency of family moves was the only significant variable. Its significance was in the direction opposite to that expected. The most effective method of locating families was to contact the Department of Social Services who provided information used to find 60% of them. CONCLUSIONS: Intervention in a therapeutic preschool day treatment program was found to be beneficial, as it enabled most of the children to progress appropriately in public school.  相似文献

What’s it all about? Making sense of Australian university learning and teaching plans     

Kathleen Gray  Alex Radloff 《高等教育研究与发展》2010,29(3):291-305

Universities put considerable resources into developing learning and teaching plans. In this paper, we examine the purpose of these plans in the context of legislative requirements, public accountability and the quality agenda. We analyse a sample of Australian university learning and teaching plans using a framework we have developed based on theory and research on strategic planning and core themes in learning and teaching. Analysis reveals considerable variation in plans’ form and format, planning characteristics and learning and teaching themes addressed and omissions of key characteristics and themes. We consider the ability of such plans to meet the needs of internal and external readers, we discuss implications for their capacity to direct and motivate changes aimed at improving learning and teaching and we challenge the higher education sector to determine more clearly the role of learning and teaching plans.  相似文献   

Comparison of kinematics in skilled and unskilled arms of the same recreational baseball players     

S. Gray  S. Watts  D. Debicki 《Journal of sports sciences》2013,31(11):1183-1194

Abstract

We examined mechanisms of coordination that enable skilled recreational baseball players to make fast overarm throws with their skilled arm and which are absent or rudimentary in their unskilled arm. Arm segment angular kinematics in three dimensions at 1000 Hz were recorded with the search-coil technique from the arms of eight individuals who on one occasion threw with their skilled right arm and on another with their unskilled left arm. Compared with their unskilled arm, the skilled arm had: a larger angular deceleration of the upper arm in space in the forward horizontal direction; a larger shoulder internal rotation velocity at ball release (unskilled arms had a negative velocity); a period of elbow extension deceleration before ball release; and an increase in wrist velocity with an increase in ball speed. It is suggested that some of these differences in arm kinematics occur because of differences between the skilled and unskilled arms in their ability to control interaction torques (the passive torque at one joint due to motion at adjacent joints). It is proposed that one reason unskilled individuals cannot throw fast is that, unlike their skilled counterparts, they have not developed the coordination mechanisms to effectively exploit interaction torques.  相似文献   

Physiological variables and performance markers of serving soldiers from two “elite” units of the British Army

Abstract

The aim of this study was to compare selected physiological variables and performance markers of soldiers from two “elite” units of the British Army. Ten soldiers from each of the two units were recruited for this study (n = 20). All participants completed three tests while carrying a 20 kg backpack load: (1) a maximal treadmill test using the Bruce protocol; (2) a 2 mile backpack run test specific to Unit A on a consistently flat tarmac road; and (3) a 29 km time-trial over hilly terrain typical of a mountainous area used by Unit B for performance assessment. Heart rate, maximal blood lactate concentration and performance (run time) were assessed during all three tests, with peak oxygen uptake also being measured during the maximal treadmill test. Measurements of anthropometry, isokinetic strength and mental toughness (MT48) were also recorded. There were no significant differences in terms of performance markers between the units (P > 0.05). Performance on the maximal treadmill test correlated with performance on the 2 mile backpack run test (r = ?0.57) and 29 km time-trial (r = ?0.66). Performance on the 2 mile backpack run test in turn correlated with 29 km time-trial performance (r = ?0.77), accounting for 59% of the variance. In conclusion, the maximal treadmill test and the 2 mile backpack run test are useful indicators of performance on the arduous hill march and could be employed in the screening and selection of potential recruits.  相似文献

Responses to Forces Influencing Cohesion As a Function of Player Status and Level of Male Varsity Basketball Competition     

Joseph J. Gruber  Gary R. Gray 《Research quarterly for exercise and sport》2013,84(1):27-36

Abstract

This exploratory study determined if the responses of male varsity basketball players to six factors influencing cohesion were a function of level of competitive intensity and/or the importance of the players to their team. Players on intact teams from five levels of competition – elementary school, junior high school, senior high school, small college and large college–responded to a cohesion questionnaire at the end of the season. Coaches designated five players with the most game playing time as “starters” and five players with the least game playing time as “reserves.” A team factor score for Team Performance Satisfaction, Self Performance Satisfaction, Task Cohesion, Affiliation Cohesion, Desire for Recognition and Value of Membership was calculated. Each team factor score served as the dependent variable in a 2 (player status) × 5 (level of competition) analysis ofcovariance design, with teams nested in the second factor. The won-loss record served as the covariate. Results indicated that “starters” were more satisfied with their own performance, were more task conscious, had a greater affiliation desire, and valued their membership on the team to a greater degree than the “reserves.” The elementary and junior high school team members were significantly more satisfied with the team's performance, were more satisfied with their own self performance, were more affiliation conscious, and valued their team membership to a greater degree than did college team members. The interaction between player status and level of competition was not significant for any of the factor scores.  相似文献
