As part of a longitudinal research study started in 1984, the purpose of this paper is to critically examine the issue of quality in an Integrated Rural Development project in Sierra Leone. An in-depth study was conducted (1990-93) to assess pre-service teacher quality, using two major indices: teacher knowledge base of subject-matter and teacher beliefs about teaching and classroom management. The results indicate that quality is affected by what knowledge teachers possess in a given subject area and their perceptions of teaching. This research is a departure from the traditional areas of looking at quality in education, that is from what happens to students in the education process to the issue of the quality of education teachers receive during their training.  相似文献

Teacher efficacy, or teachers’ feelings about their abilities in the classroom, remains a major component of educational research. We know that despite participating in shared or similar experiences, some preservice teachers (PSTs) develop feelings of teacher efficacy and some do not. Yet, in-depth examinations into the specific practices of successful host schools are scarce in the deep field of teacher efficacy research. We examine the deliberate actions of one Midwestern elementary school to establish a climate and co-teaching process that deliberately seeks to foster PST success and feelings of confidence in the classroom. We also discuss implications for teacher education.  相似文献

Abstract

Squash is a popular racket sport that requires intermittent activity with frequent bursts of near maximal-intensity exercise. Consequently, effective physiological and thermoregulatory responses are important contributors to performance during squash match-play. Controlled field-based simulation protocols have been introduced in a growing number of sports, which allow sports scientists to investigate changes in physiology and the efficacy of various interventions in sport-specific contexts. This study aimed to develop an exercise protocol that simulates the physiological requirements of elite squash match-play. Eight elite junior squash players (age 16.2 ± 0.8 years, height 1.76 ± 0.06 m, body mass 61.3 ± 5.9 kg; mean ± s) completed the following in a randomized order: (1) a squash match against a player of similar standard and (2) a squash-specific incremental exercise protocol (multistage squash test [MST]) followed by the squash simulation protocol (SSP). The multistage squash test was continued for 18.0 ± 1.0 min and elicited near maximal post-MST heart rates, blood lactate concentrations and ratings of perceived exertion (198 ± 9 beats · min?1, 5.7 ± 1.7 mmol · l?1 and 18 ± 1, respectively). The SSP was 12.2 min in length compared with mean game length during competitive matches of 10.0 ± 1.6 min (P = 0.27). Peak heart rates were similar during the SSP and match-play (192 ± 11 and 189 ± 6 beats · min?1, respectively; P = 0.44). Mean exercising heart rates were similar during the SSP (180 ± 8 beats · min?1) and match-play (179 ± 13 beats · min?1; P = 0.73). Peak blood lactate concentrations during the SSP and match-play were 3.5 ± 1.5 and 2.4 ± 1.2 mmol · l?1 (P = 0.07), respectively. Peak ratings of perceived exertion during the SSP and match-play were similar (17 ± 2 and 17 ± 2, respectively; P = 0.64). It was concluded that the SSP closely replicated the demands of squash match-play in elite junior squash players. Furthermore, the SSP provides coaches and scientific support staff with a controlled squash-specific exercise protocol that has potential application in the objective investigation of a range of interventions such as training programmes, nutritional supplements and strategies to maintain core body temperature.  相似文献

The paper examines how information and communication technology can be utilized for resource sharing among university libraries in Nigeria. It was based on the study and review of recent library and information science literature on both print and electronic resources. It discusses the meaning of information and communication technology, resource sharing practices, and how information and communication technology facilitates resource sharing. It traces the history of resource sharing among Nigerian libraries. The current state of information and communication technology application and utilization in Nigeria and its university libraries is revealed, with emphasis on university libraries that are located in different zones of the country. The paper examines challenges facing Nigerian University Libraries with respect to information and communication technology application and utilization for resource sharing, as well as to areas of library operations to which information and communication technology can be applied and utilized for resource sharing. It concludes by proffering solutions for viable information and communication technologies–based cooperation among university libraries in Nigeria.  相似文献

Despite recognition that social inclusion is a primary goal within the field of human services, people with disabilities continue to live lives of clienthood, marginalisation, and exclusion and human services staff struggle to make social inclusion a priority. The purpose of this study was to explore the perspectives of human services staff about their experiences of an organisationally inspired initiative intended to change the focus of their everyday practices to better facilitate the social inclusion of persons with disabilities. A qualitative case study was used to gather observations, field and reflective notes, semi-structured interviews with staff (n = 15), and reflexive journaling. Thematic analysis of the data led to three themes: (a) challenges, old and new, (b) needing (careful) change, and (c) creating, learning and working together. These findings highlight the complexity of how to create change in the field of human services, but also demonstrate how innovative approaches have the potential to shift and reimagine how human services workers can better support people with disabilities in living meaningful lives.  相似文献

A comprehensive model of instruction should include as one component a representation of the instructional subject matter. In order to represent subject matter a theory for structuring subject matter is required. A general theory for structuring and describing such structures is provided herein. Subject matter structure is composed of two components: content and tasks. The theory presented to structure content is based on the paradigm of axiomatics. Content elements consist of Primary Notions, Secondary Notions, Basic Principles and Established Principles. Two relationships, “used in the formulation of” and “used to establish,” provided the basic structure relating these Constituents. Coordinating relations associate task subsets with content constituents. Task subsets provide the theoretical analog to criterion tests. The notion of dependency is introduced and investigated briefly. Also, a method is provided for developing the complete set of dependency relationships for content constituents. Three examples are provided to further clarify the theoretical model.  相似文献

This article addresses the historical divide between gender development researchers and developmental researchers working with immigrant populations, advocating for the benefits gained by bridging research approaches and interests. For gender researchers, the immigrant context allows for the examination of how children embedded in multiple cultures navigate the potentially conflicting information about appropriate gendered behaviors and attitudes. Furthermore, research focusing on immigrant development can move beyond examining gender differences and benefit from understanding the ways in which gender differences develop. This bridging seems particularly relevant in middle childhood, given (a) the exposure to multiple contexts which increase the salience of cultural differences between home and outside-of-home environments and (b) greater awareness and internalization of collective identities (i.e., gender, ethnicity).  相似文献

We sought to determine the sex-specific effects of an acute bout of free-weight resistance exercise (RE) on pulse wave reflection (aortic blood pressures, augmentation index (AIx), AIx at 75?bpm (AIx@75), augmentation pressure (AP), time of the reflected wave (Tr), subendocardial viability ratio (SEVR)), and aortic arterial stiffness in resistance-trained individuals. Resistance-trained men (n?=?14) and women (n?=?12) volunteered to participate in the study. Measurements were taken in the supine position at rest, and 10 minutes after 3 sets of 10 repetitions at 75% 1-repetition maximum on the squat, bench press, and deadlift. A 2?×?2?×?2 ANOVA was used to analyse the effects of sex (men, women) across condition (RE, control) and time (rest, recovery). There were no differences between sexes across conditions and time. There was no effect of the RE on brachial or aortic blood pressures. There were significant condition?×?time interactions for AIx (rest: 12.1?±?7.9%; recovery: 19.9?±?10.5%, p?=?.003), AIx@75 (rest: 5.3?±?7.9%; recovery: 24.5?±?14.3%, p?=?.0001), AP (rest: 4.9?±?2.8?mmHg; recovery: 8.3?±?6.0?mmHg, p?=?.004), and aortic arterial stiffness (rest: 5.3?±?0.6?ms; recovery: 5.9?±?0.7?ms, p?=?.02) with significant increases during recovery from the acute RE. There was also a significant condition?×?time for time of the reflected wave (rest: 150?±?7?ms; recovery: 147?±?9?ms, p?=?.02) and SEVR (rest: 147?±?17%; recovery: 83?±?24%, p?=?.0001) such that they were reduced during recovery from the acute RE compared to the control. These data suggest that an acute bout of RE increases AIx, AIx@75, and aortic arterial stiffness similarly between men and women without significantly altering aortic blood pressures.  相似文献

Our study determined the impact of emotional intelligence (EI) on teachers' attitudes, concerns and sentiments about inclusive education while controlling for teachers' professional-related factors. This is predicated on the increasing influence of EI on teacher effectiveness. The sample size consisted of 508 regular classroom teachers. Using hierarchical regression analysis, our findings revealed that teacher EI was significantly associated with attitude and concerns about inclusive education after controlling teacher professional-related factors. There was no significant relationship between EI and teachers' sentiments about inclusive education, and teachers' professional-related factors did not account for individual contributions to the variances in teachers' sentiments. It was concluded that teachers' EI, may be a crucial factor that can impact aspects of teachers' perception of inclusive education such as attitude, and concerns about inclusive education but may not be able to erase teachers' deep-seated beliefs on inclusion. Implications of the study were highlighted.  相似文献
