This study contributes to our understanding of the complex issues inherent in dealing with the heterogeneity of current high school science classrooms, by reporting on in-depth interviews with 38 experienced biology teachers. Analyses of teachers' responses revealed complex and occasionally counter-intuitive relationships among: (a) their perceptions of what was distinctive about their school, its biology program, or their students; (b) their allocation of class time; (c) their efforts to individualize instruction and meet the needs of a heterogeneous student population; (d) their student outcome goals; and (e) the methods they used to evaluate student progress. Thus, for example, of the 9 teachers who cited the diversity of their students. 4 also commented on their poor motivation, but another 4 also commented on their high motivation. In addition, teachers reported using a similar range of instructional formats but for different reasons, depending on the characteristics of their students (e.g., cooperative learning groups used to compensate for poor attention spans, to challenge bright students, and to foster social tolerance). Discussion of these findings addresses several points of relevance for science education, teacher preparation, and curriculum reform. © 1996 John Wiley & Sons, Inc. 相似文献

Lifelong learning is recognized as an important tool to reduce social exclusion, but out of the many investigations into the provision of lifelong learning in Europe none has yet sought to examine the specific situation of mental health care service users. This study examines the provision of lifelong learning for this disadvantaged group; it identifies current policies and explores the access to, and nature of, lifelong learning practices for mental health care service users in eight European countries. Data have been collected through a literature and policy review and through questionnaires completed by mental health practitioners in the eight countries. The study found broad compliance amongst the eight countries with the Lisbon policy goals on lifelong learning, but evidence of specific lifelong learning provision for mental health care service users is patchy and sporadic. The study identified the main benefits of, and the barriers to, the participation in lifelong learning for mental health care service users from the viewpoint of mental health professionals and practitioners. The implications for practice were described, and suggestions for actions were made for improving the lifelong learning provision for the target group. 相似文献

In the past decade, we have seen an increased focus on measuring the impact of zoos, aquariums, and other free‐choice learning environments on the conservation‐related knowledge, attitudes and behavior of the visiting public. However, no such studies have been conducted on the impact of such environments on the staff working in these facilities – the very staff that in turn interact with the public on a daily basis. Clearly these interactions are recognized as being important; for example, the thousands of staff employed by Disney’s Animal Kingdom are regularly provided with conservation‐related training – both formal, in‐class experiences, as well as more informal experiences with animals; these are a mixture of compulsory and freely chosen experiences. An exploratory qualitative study was conducted to investigate the impact of working at Disney’s Animal Kingdom on staff knowledge, attitudes, and behavior related to animals and their conservation. The resulting findings offer preliminary evidence that working in an environmentally themed setting has a positive impact on all of these variables, and that particular experiences – notably experiences in back‐of‐house animal holding areas and with animal staff – are key. These findings suggest that further investigation into the impact of working in such learning settings could be fruitful in understanding the role that the work place plays in supporting the free‐choice learning of staff. This is important both from the perspective of the staff themselves, and in relation to the impact that these individuals may have on visitors to free‐choice learning settings. 相似文献

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

Failure Modes and Effects Analysis (FMEA) is a proactive assessment tool originally created for quality assurance in manufacturing industries. FMEA involves the assignment of rankings for frequency, severity, and detection of errors within a process. Catalogers at ProQuest undertook an innovative project to use FMEA to evaluate MARC record production. This article provides an overview of FMEA for process evaluation and summarizes an application for cataloging. It considers the tool's value for error-proofing in MARC record creation and how FMEA might be applied more effectively in a variable environment. 相似文献

AbstractA large body of evidence now shows that higher protein intakes (2–3 times the protein Recommended Dietary Allowance (RDA) of 0.8 g/kg/d) during periods of energy restriction can enhance fat-free mass (FFM) preservation, particularly when combined with exercise. The mechanisms underpinning the FFM-sparing effect of higher protein diets remain to be fully elucidated but may relate to the maintenance of the anabolic sensitivity of skeletal muscle to protein ingestion. From a practical point of view, athletes aiming to reduce fat mass and preserve FFM should be advised to consume protein intakes in the range of ~1.8–2.7 g kg?1 d?1 (or ~2.3–3.1 g kg?1 FFM) in combination with a moderate energy deficit (?500 kcal) and the performance of some form of resistance exercise. The target level of protein intake within this recommended range requires consideration of a number of case-specific factors including the athlete's body composition, habitual protein intake and broader nutrition goals. Athletes should focus on consuming high-quality protein sources, aiming to consume protein feedings evenly spaced throughout the day. Post-exercise consumption of 0.25–0.3 g protein meal?1 from protein sources with high leucine content and rapid digestion kinetics (i.e. whey protein) is recommended to optimise exercise-induced muscle protein synthesis. When protein is consumed as part of a mixed macronutrient meal and/or before bed slightly higher protein doses may be optimal. 相似文献
