In this text, which was originally delivered as a speech, I discuss the massive critique of teachers in the public discourse on education in Sweden over the last decade. I speak in defence of teachers, and since I am a teacher I speak in defence of myself. The critique of teachers, schooling, and teacher education has been so overbearing that a purely rational response is simply not possible. Therefore, my response is rhetorical in tone. In highlighting the passion of teaching, I lift something central for teachers, which is seldom or never taught about teaching in teacher education. Neither is the passion of teaching present in the public discourse on education. Passion, I argue in the article, is that which adds excess or an overflow of meaning that cannot be contained within the order of discourse and which therefore puts this discourse out of balance. Finally, I discuss a new balance beyond this order in the context of a classroom. In a concluding section, I highlight the struggle over borders which define who can speak and think in “good” order and who cannot. 相似文献

The effects of training with overweight and underweight cricket balls on fast-bowling speed and accuracy were investigated in senior club cricket bowlers randomly assigned to either a traditional (n = 9) or modified-implement training (n = 7) group. Both groups performed bowling training three times a week for 10 weeks. The traditional training group bowled only regulation cricket balls (156 g), whereas the modified-implement training group bowled a combination of overweight (161-181 g), underweight (151-131 g) and regulation cricket balls. A radar gun measured the speed of 18 consecutive deliveries for each bowler before, during and after the training period. Video recordings of the deliveries were also analysed to determine bowling accuracy in terms of first-bounce distance from the stumps. Bowling speed, which was initially 108 +/- 5 km h(-1) (mean +/- standard deviation), increased in the modified-implement training group by 4.0 km x h(-1) and in the traditional training group by 1.3 km x h(-1) (difference, 2.7 km x h(-1); 90% confidence limits, 1.2 to 4.2 km x h(-1)). For a minimum worthwhile change of 5 km x h(-1), the chances that the true effect on bowling speed was practically beneficial/trivial/harmful were 1.0/99/< 0.1%. For bowling accuracy, the chances were 1/48/51%. This modified-implement training programme is not a useful training strategy for club cricketers. 相似文献

While the need to present food science information effectively is viewed as a critical competency for food scientists by the Institute of Food Technologists, most food scientists may not receive adequate training in this area. Effective presentations combine both scientific content and delivery mechanisms that demonstrate presenter enthusiasm for the topic and generate audience interest. This paper provides food science presentation “best practices” based upon the results of the author's 10 y of experience teaching communication skills to 1st‐year graduate students. Topics include development of a “Presentation Inventory” that encourages presenters to consider why they are presenting, who they are presenting to, what information they plan to present, and how they plan to present the information. More specific sections of the paper address presentation introductions and conclusions, developing visual aids, responding to audience questions, flow, pacing, and time management, technological competency, and tips on how to practice a presentation. Such information should be applicable to all types of food science practitioners including undergraduate and graduate students, postdoctoral scholars, teaching and research academics, and government, industrial, and consulting food scientists. An awareness of such “best practices” among presenters of food science information can help raise the bar to improve the quality of contemporary food science presentations. 相似文献

OBJECTIVE: This study examined the convergent and discriminant validity of two trauma symptom measures, the Trauma Symptom Checklist for Children (TSCC) [Briere, J. (1996). Trauma Symptom Checklist for Children (TSCC). Odessa, FL: Psychological Assessment Resources] and the Trauma Symptom Checklist for Young Children (TSCYC) [Briere, J. (2005). Trauma Symptom Checklist for Young Children (TSCYC). Odessa, FL: Psychological Assessment Resources]. METHODS: Children's scores on the TSCC and their caretakers' ratings on the TSCYC were analyzed in a study of 310 children presenting to one of two child abuse treatment centers. RESULTS: TSCC and TSCYC scales generally converged in their assessment of symptomatology in maltreated children. Equivalent scales measuring anxiety, depression, anger, dissociation, and sexual concerns were generally most correlated with one another. Similarly, the Posttraumatic Stress-Intrusion (PTS-I) scale of the TSCYC correlated highest with the Posttraumatic Stress (PTS) and Anxiety (ANX) scales of the TSCC, the TSCYC Posttraumatic Stress-Arousal (PTS-AR) scale was correlated with the TSCC ANX scale, and the TSCC PTS scale was most correlated with the TSCYC ANX, PTS-I, and Sexual Concerns (SC) scales. The TSCYC Posttraumatic Stress-Avoidance scale was unrelated to any TSCC scale. Discriminant function analysis revealed that the TSCC PTS scale was the best single predictor of sexual abuse-related PTSD status as identified by the TSCYC. CONCLUSIONS: The TSCC and TSCYC display moderate convergent and discriminant validity with respect to one another, despite different information sources. Nevertheless, the relatively small association between relevant TSCC and TSCYC scales indicates that different symptom informants may have different perspectives on the child's symptomatology; an outcome that may be beneficial when both measures are administered simultaneously. PRACTICE IMPLICATIONS: These results reinforce the notion that both child- and parent/caretaker report measures should be used in the evaluation of traumatized children, so that multiple sources of information can be considered simultaneously. In the current context, administration of the TSCC to the child and the TSCYC to the caretaker, when appropriate (i.e., in children 8-12 years of age) may yield more clinical information on the child's symptomatology than either measure would alone-perhaps especially in cases when one of the two respondents under- or over-reports the child's distress. 相似文献

Abstract Differences in physiological, physical, and technical demands of small-sided basketball games related to the number of players, court size, and work-to-rest ratios are not well characterised. A controlled trial was conducted to compare the influence of number of players (2v2/4v4), court size (half/full court) and work-to-rest ratios (4x2.5 min/2x5 min) on the demands of small-sided games. Sixteen elite male and female junior players (aged 15–19 years) completed eight variations of a small-sided game in randomised order over a six-week period. Heart rate responses and rating of perceived exertion (RPE) were measured to assess the physiological load. Movement patterns and technical elements were assessed by video analysis. There were ~60% more technical elements in 2v2 and ~20% more in half court games. Heart rate (86 ± 4% & 83 ± 5% of maximum; mean ± SD) and RPE (8 ± 2 & 6 ± 2; scale 1–10) were moderately higher in 2v2 than 4v4 small-sided games, respectively. The 2v2 format elicited substantially more sprints (36 ±12%; mean ±90% confidence limits) and high intensity shuffling (75 ±17%) than 4v4. Full court games required substantially more jogging (9 ±6%) compared to half court games. Fewer players in small-sided basketball games substantially increases the technical, physiological and physical demands. 相似文献
