This article explores potential changes in the power relationships among teachers and principals under four emerging forms of structured teacher involvement in schoolwide decision making: Instructional Leadership Teams, Principals' Advisory Councils, School Improvement Teams, and Lead Teacher Committees. Each organizational model is described in terms of its purpose, its operation, the role of teachers and the principal, and its potential impact on teacher leadership and empowerment. A conceptual framework that views organizational power in terms of access to resources and the ability to obtain cooperation from other actors (Kanter, 1979) is utilized to gauge potential changes in the power of principal and teacher roles under each of these emerging models. The conceptual analysis suggests that models seeking to empower teachers and improve student learning must provide for increased interaction among teachers in curricular and instructional decision making.Presented at the annual meeting of the American Educational Research Association, New Orleans, April 1988. 相似文献

A checklist evaluation on thirty-seven Women's Studies programs conducted using the individual institutions' online public access catalogs (OPACs) is presented. Although Women's Studies collections are very difficult to build, an evaluation of existing programs shows that collections, for the most part, have managed substantial coverage of the subject area. 相似文献

Abstract This study investigated the effects of three types of recovery procedure on (a) circulatory recovery from a standardized bicycle ergometer exercise, (b) performance in a second standardized bicycle ergometer exercise, and (c) circulatory recovery from the second exercise. The recovery procedures were complete rest, light activity, and cold showers. Each of 10 male subjects underwent each recovery procedure on separate days. Analysis of variance for a randomized complete blocks design was used in the analysis of the data. Results indicated that cold showers decreased recovery heart rate after the first standardized exercise from 115 to 96 beats/minute and after the second exercise from 164 to 152 beats/ minute when compared with the other two conditions. Speed of performance in the second exercise was improved from 40.4 and 40.3 sec. in the case of rest and light activity to 38.9 sec. for cold showers. These improvements were all statistically significant at the .05 level. Three physiological explanations, not necessarily independent, are advanced: (a) local vasoconstriction of the skin vessels and vasodilatation of the muscle vessels causing a greater proportion of total blood flow to the working muscles, (b) establishment of a greater thermal gradient between the core and shell of the body allowing heat movement to the surface of the body by conduction between tissues rather than by skin blood flow, and (c) a decrease in sweat rate, thereby suppressing release of bradykinin, a vasodilator substance. 相似文献

Abstract Nineteen college men and women (aged 18–23 yrs, × = 21.1) were studied to ascertain the force-time components of a rapid maximal voluntary isometric contraction (MVC) for ankle dorsiflexors, knee extensors, elbow flexors, wrist flexors and hand grip. Standardized isometric strength testing protocol was used. After a practice period subjects were instructed to make an MVC without jerking and as quickly as possible, for each of the muscle actions noted above. Force readings were taken from a load cell assembly through an analogue-to-digital converter and analyzed to yield time values for MVC, 3/4 MVC, 1/2 MVC, and 1/4 MVC. The results indicated significant differences (p < .01) between the responses of the men and women, with the women reaching full MVC more rapidly than the men. Also, there were significant differences among the five muscle groups tested, with the wrist flexor muscle group developing MVC most quickly, while the knee extensors took the longest time to full MVC. Based upon these data it may be concluded that the time to full MVC differs between men and women, and also that the time to full MVC differs among the five muscle groups tested in this experiment. 相似文献

Following treatment in a therapeutic day treatment program, a group of 35 maltreated children were compared to a matched group of 35 maltreated children who had not been enrolled in a therapeutic day treatment program. The results of matched pairs t-test analyses indicated that the treatment subjects had significantly higher developmental scores in five areas of development--fine motor, cognitive, gross motor, social/emotional, and language. Further, pretest and posttest comparisons of the percentile scores of the treatment group indicated that the posttest scores were significantly higher than the pretest scores. This study demonstrates that remediation of developmental delays in maltreated children under the age of 6 years can be accomplished through an intensive day treatment program. 相似文献

This study describes the development of an assessment to evaluate the well-being of PhD researchers using a clinically approved methodology that places the perceptions and experiences of the subject population at the heart of its construction. It identifies and assesses the range and relative importance of seven distinct dimensions which are shown to impact adversely on the perceived well-being of student researchers across all stages of their studies. According to the findings, the well-being of doctoral students comprises needs relating to development, facilities, home and health, research, social, supervisor and university. The instrument was found to demonstrate good content validity and internal reliability. Its use offers new insights into the experiences of early career researchers and may inform efforts to better support them. This, in turn, may have a positive impact upon retention levels and future career choices for this research population. 相似文献

This article presents a quasi-experimental study comparing the impact of two technology-related teacher professional development (TTPD) designs, aimed at helping junior high school science and mathematics teachers design online activities using the rapidly growing set of online learning resources available on the Internet. The first TTPD design (tech-only) focused exclusively on enhancing technology knowledge and skills for finding, selecting, and designing classroom activities with online resources, while the second (tech?+?pbl) coupled technology knowledge with learning to design problem-based learning (PBL) activities for students. Both designs showed large pre-post gains for teacher participants (N?=?36) in terms of self-reported knowledge, skills, and technology integration. Significant interaction effects show that teachers in the tech?+?pbl group had larger gains for self-reported knowledge and externally rated use of PBL. Three generalized estimating equation (GEE) models were fit to study the impact on students?? (N?=?1,247) self reported gains in behavior, knowledge, and attitudes. In the resulting models, students of tech?+?pbl teachers showed significant increases in gain scores for all three outcomes. By contrast, students of tech-only teachers showed improved gains only in attitudes. 相似文献

The global context of contemporary higher education demands international benchmarks. Quality assurance of teaching and learning would benefit from the insights gained from cross-cultural assessments. If cross-cultural assessments are used it is imperative that equivalence is assured, requiring attention to the technical standards used. In this paper we draw on our experiences implementing the Organisation for Economic Cooperation and Development’s Assessment of Higher Education Learning Outcomes (AHELO) Feasibility Study across 17 countries. We consider the key standards required in a number of core technical areas to achieve equivalence. We discuss how different elements were achieved in the AHELO Feasibility Study. These include the development of assessment materials for use across languages; selection and engagement of students; delivery of assessment materials and analysis of assessment data. 相似文献

This article describes the litigation involving SkyRiver Technology Solutions and Online Computer Library Center, Inc. (OCLC). At its heart is who owns library catalog records. It begins with an overview of the organizations and examines their histories, products, and positions in the library services market in an attempt to understand and explain the background for the current situation. It continues with an overview of the lawsuit, including the plaintiffs’ claims for relief and the major arguments in OCLC's motion to dismiss. Finally, it turns to what the lawsuit means for the library services marketplaces, what potential changes may occur, and what OCLC's future might look like. 相似文献
