AbstractThe aim of this study was to examine the acute response to plasma and salivary cortisol and testosterone to three training protocols. Ten trained endurance athletes participated in three experimental trials, such as interval training (INT), tempo run (TEMP) and bodyweight-only circuit training (CIR), on separate days. Blood and saliva samples were collected pre- and 0, 15, 30 and 60 min post-exercise. Peak post-exercise salivary cortisol was higher than pre-exercise in all trials (P < 0.01). After INT, salivary cortisol remained elevated above pre-exercise than 60 min post-exercise. Salivary testosterone also increased post-exercise in all trials (P < 0.05). Plasma and salivary cortisol were correlated between individuals (r = 0.81, 0.73–0.88) and within individuals (r = 0.81, 0.73–0.87) (P < 0.01). Plasma and salivary testosterone was also correlated between (r = 0.57, 0.43–0.69) and within individuals (r = 0.60, 0.45–0.72), (P < 0.01). Peak cortisol and testosterone levels occurred simultaneously in plasma and saliva, but timing of post-exercise hormone peaks differed between trials and individuals. Further investigation is required to identify the mechanisms eliciting an increase in hormones in response to CIR. Furthermore, saliva is a valid alternative sampling technique for measurement of cortisol, although the complex, individual and situation dependent nature of the hormone response to acute exercise should be considered. 相似文献

Since the introduction of nursing into tertiary institutions in Australia in 1975, there has been increasing interest in the
teaching of physical science to nurses. Various courses in physical science for nurse students have been developed. They vary
in length and content but there is agreement that concepts taught should be closely related to nursing applications. The choice
of relevant concepts tends to be made by individual curriculum developers. This paper reports an examination of the use of
physical science concepts and their relevance from the perspective of registered nurses practising in general ward areas.
Inherent in this study is the premise that for registered nurses to have ideas of the physical science underlying their practice
they must have constructed meaning first for these concepts. Specific chemical concepts related to solutions are discussed
in these terms.

In 1997, the DfEE suggested that schools should consider 'setting' pupils by ability as it was believed that this would contribute to raising standards. This survey of primary schools aimed to establish the extent to which primary schools, with same and mixed age classes, implement different grouping practices including setting, streaming, within class ability and mixed ability groupings for different curriculum subjects. Schools were asked to complete a questionnaire indicating their grouping practices for each subject in each year group. The findings showed that schools predominantly adopted within class ability groupings, either mixed or ability grouped, for most subjects. Ability grouping (within class and setting) was most common in mathematics, followed by English and science. Its implementation increased as pupils progressed through school. The type of setting adopted, same or cross-age, tended to reflect the nature of the class structures within the school. 相似文献

Using narrative inquiry as a research method, four mathematics and mathematics education faculty members explored the integration of theoretical perspectives into their personal narratives as they developed a community of practice. Initially their focus was strictly on improving their students’ mathematical knowledge. As their community of practice matured, however, their work took on a larger meaning as they contributed to the institution’s strategic goal of raising the annual dollar amount of external funding and to the development of their personal and collective identities. This unusual level of inter-departmental collaboration has been recognized by the institution’s highest administrators, who have called upon its members to develop new, collaborative partnerships with regional school districts and community colleges. 相似文献

The Microelectronics WebLab at MIT allows students to do actual (not simulated) laboratory research on state-of-the art equipment
through the Internet. This study assesses the use of WebLab in a junior-level course on microelectronic devices and circuits
in 2004–05 and 2005–06. In quantitative surveys and qualitative interviews, students and faculty reported that WebLab was
effective as an instrument of learning, and grew more so with refinements of the program. WebLab allowed undergraduates to
learn at their own pace and on their own schedules. It enabled them to use different processes of learning (intuitive, visual,
abstract), and it gave them an opportunity to link individual and collaborative effort in creative combinations. Online laboratories
on this model have broad applications in the experimental sciences and in other research-oriented disciplines. 相似文献

Evaluation of college and university teaching is considered in the context of growing demands for accountability of educational institutions and particular roles of faculty in achieving goals for which these institutions are believed to be accountable. In the first of two papers,* three contemporary aprroaches to evaluation of teaching in higher education are critically reviewed. All three of these approaches-assessment of learning outcomes, assessment of teacher characteristics and analysis of pedagogical behaviors-are found to be defective on logical, theoretical and empirical grounds. A common thread of deficiency is the absence of a coherent theoretical framework for analysis of teaching and phenomena associated with teaching. Specific defecs are analyzed in each of the three approaches as well as in the ubiquitous methodology of rating of teaching performance. In analysis of evaluation by assessment of learning outcomes, teaching is shown to be neither necessary nor sufficient to subsequent learning outcomes. Assessment of teacher characteristics fails to identify those characteristics peculiarly indigenous to teaching as a generic activity. Analysis of pedagogical behaviors fails to distinguish critical teaching acts from more general teacher characteristics interpretable in terms of teacher personality. Furthermore, no adequate basis is provided for normative interpretation of data pertaining to pedagogical behaviors. The use of rating scales to provide data about teacher characteristics or pedagogical behavior rests on assumed rather than demonstrated validity of results. Evidence of validity or meaningfulness is replaced by evidence of consistency which is often spurious. The first paper concludes with an outline of requirements for a more constructive approach to the task of teacher evaluation. In a second paper, an outline of a theory of teaching is sketched which conforms to these requirements. Realization of this theoretical structure in teaching assessment report forms is described. Tentative conclusions from trial use of forms-in-development and recommendations for additional data sources are discussed in terms of their potential contribution to improvement in teaching. 相似文献
