In einer retrospektiven Befragung von vier Kohorten (Patentierung 1963–65, 1973–75, 1983–85 und 1993–95) ehemaliger Absolventinnen und Absolventen der seminaristischen Primarlehrerausbildung im Kanton Bern (Schweiz) wurden Daten zur beruflichen Mobilit?t und aktuellen Berufst?tigkeit erhoben. Auf der Basis von Besch?ftigungsgrad und T?tigkeitschronologie konnten fünf Karrieretypen gebildet werden — Nicht-Einstieg, Verbleib, Reduktion, Ausstieg und Wiedereinstieg —, die bezüglich beruflicher Beanspruchung, motivationaler Haltung und Berufszufriedenheit beschrieben wurden. Mehr als die H?lfte der Befragten arbeitet aktuell nicht mehr als Primarlehrer, jedoch haben nur wenige das Berufsfeld Bildung und Schule verlassen. Die Ergebnisse zeichnen ein weit günstigeres Bild der beruflichen Karriere von Lehrkr?ften als die bisherige Forschung, die zumeist auf „überlebende“ im Lehrerberuf beschr?nkt ist. Auff?llig ist die starke Determination der Karriere von weiblichen Lehrkr?ften durch die traditionelle Geschlechtsrollenteilung, und zwar in allen untersuchten Kohorten.  相似文献

This study represents an expansion of previous research investigating the prevalence of sleep difficulties in college students. Sleep quality and sleep habits were assessed via self‐report questionnaires. Poor sleep quality was reported by 22.6% of participants, whereas 65.9% replied that they experienced occasional sleep problems. More than half of the respondents noted feeling tired in the morning. Implications for counselors and their institutions are discussed.  相似文献

In the modern era, the prevailing model of public education has been that of “one size fits all”, with private schooling being a small but notable exception. Language (of instruction) was generally viewed as a minor variable readily overcome by standard classroom instruction. As researchers have sharpened their focus on the reasons for educational failure, language has begun to emerge as a significant variable in producing gains in educational efficiency. This paper reports the intermediate result of a controlled study in a very rural area of a developing country designed to examine the effect of language of instruction on educational outcomes. In the experimental schools, children are taught to read first in the local language (via the local language) and are taught other key subjects via the local language as well. English is taught as a subject. Teachers in the control or standard schools continue the standard national practice of teaching all subjects in either English or Filipino, neither of which is spoken by children when they begin school. Year-end standardised testing was done in all subjects throughout grades one to three as a means of comparing the two programme methodologies.  相似文献

In the project ‘Competence-Driven Project Portfolio Analysis’ (CDPPA), an integrated system for supporting R&D project selection, staff assignment and activity scheduling with special consideration of the strategic development of competencies has been designed and implemented prototypically. The system has been field-tested at the Electronic Commerce Competence Center (EC3), a public–private partnership R&D enterprise. Experiences from this trial application are summarised and discussed, particularly concerning data collection and competence measurement, the benefits and limits of the chosen multi-criteria decision analysis approach, the evaluation of introduced changes to the decision-making processes, and the transparency of the formal planning model and its components.  相似文献

Swing trajectory and ground reaction forces (GRF) of 30 collegiate baseball batters hitting a pitched ball were compared between a standard bat, a bat with extra weight about its barrel, and a bat with extra weight in its handle. It was hypothesised that when compared to a standard bat, only a handle-weighted bat would produce equivalent bat kinematics. It was also hypothesised that hitters would not produce equivalent GRFs for each weighted bat, but would maintain equivalent timing when compared to a standard bat. Data were collected utilising a 500 Hz motion capture system and 1,000 Hz force plate system. Data between bats were considered equivalent when the 95% confidence interval of the difference was contained entirely within ±5% of the standard bat mean value. The handle-weighted bat had equivalent kinematics, whereas the barrel-weighted bat did not. Both weighted bats had equivalent peak GRF variables. Neither weighted bat maintained equivalence in the timing of bat kinematics and some peak GRFs. The ability to maintain swing kinematics with a handle-weighted bat may have implications for swing training and warm-up. However, altered timings of kinematics and kinetics require further research to understand the implications on returning to a conventionally weighted bat.  相似文献
