Es gibt einige Hinweise darauf, dass Vorstellungen vom Lehren und Lernen sowohl für das Handeln der Lehrkr?fte im Unterricht als auch für Zielkriterien auf der Ebene der Schüler eine Rolle spielen. Dabei gelten konstruktivistisch orientierte Sichtweisen als besonders günstig. Empirische Untersuchungen dazu gibt es jedoch bislang nur auf einzelne fachdidaktische Inhaltsbereiche bezogen. In der vorliegenden Studie werden konstruktivistisch orientierte Lehrereinstellungen mit Merkmalen des Unterrichts (?ffnung des Unterrichts im Hinblick auf Entscheidungsm?glichkeiten für Schüler/-innen und Strukturierung des Unterrichts) sowie mit Einsch?tzungen der Schüler/-innen (Selbstbestimmungsempfinden und Interessantheit des Unterrichts) in Beziehung gesetzt. Die Ergebnisse best?tigen die Theorie: In den Klassen der Lehrer/-innen mit überwiegend konstruktivistischen Vorstellungen von Lernen und Lehren gibt es mehr Freir?ume, ohne dass der Unterricht weniger strukturiert abl?uft. Zudem empfinden sich die Schüler/-innen als selbstbestimmter und sch?tzen den Unterricht als interes-santer ein.  相似文献

This article, which examines variables affecting scores on a test of library skills, finds that the frequency with which students receive assignments requiring library research is the best predictor of a score. The unevenness is students' research skills has implications for bibliographic instruction.  相似文献

THIS BRIEF COMMUNICATION addresses program abuse in out-of-home placement which deepens what we identify as the alienation response in the already alienated child. Alienation is defined as a state of feeling separate, apart, not being able to relate effectively with another, not belonging, and with impaired ability to connect the inside world of feelings with the outside environment. Program abuse is seen as any act or condition permitted in a program that further alienates a child. In evaluating a child's degree of alienation and developing creative methods to reach the most severely “child alone,” the use of the Alienation Chart in Figure 1, has been helpful to our staff.  相似文献

This paper explores the differing perceptions and identity responses (identification, apathy and disidentification) that potentially exist in relation to one non-profit Community Sport Organisation (CSO), and whether they explain variations in individuals’ existing values and beliefs, sport interest, community identification and views about one organisation's legitimacy. Data were collected using a quantitative online survey (n = 390), then analysed using Confirmatory Factor Analysis (CFA) and Multiple Analysis of Variance (MANOVA) to test three hypotheses investigating whether existing values and beliefs, shared community values, local players, organisational practices and sport interest varied based on perception of organisational image and identity response. Based on the contributions of this study, non-profit CSOs should spend time developing understanding of the key dimensions that make them relevant to constituents and to decipher the values and beliefs that underpin what external audiences expect from organisations. In addition, understanding specifically what a CSO's audience expects is fundamental if the organisation is to be perceived as legitimate in relation to its purpose.  相似文献

In information retrieval research, models and systems traditionally assume that a single person is querying and reviewing the results. However, several empirical studies of professional practice identified collaboration during IR as everyday work patterns in order to solve a shared information need and to benefit from the diverse expertise and experience of the team members. Moreover, most IR systems that are employed in professional work routines are designed for individual use and prototype collaborative systems are too limited to support use in todays work practice. To bridge this gap, this papers develops and formalizes a decision theoretic approach towards supporting a team of people that explicitly set out together to resolve a shared information need. We develop a formal cost model for collaborative IR that considers the trade-off between estimated relevance of a document as well as estimated document redundancy. From this cost model, we use a decision theoretic approach to derive the notion of activity suggestions, that is, a formal optimum criterion that describes optimum collaboration strategies in IR as the solution of an integer linear program. Those collaboration strategies are suggested to team members with the aim to facilitate the collaborative performance of information retrieval tasks. We demonstrate the application of our model by means of search result division in two collaborative search tasks. In the conducted experiments, we study the effects of different domain knowledge and resulting relevance assessments of team members in four different conditions. The gathered results indicate that our approach can improve the retrieval effectiveness of teams in recall-oriented tasks.  相似文献

This article provides a reflection on the outcomes of an international collaboration between health librarians and academics at York St John University and Pacific University Oregon. In particular, it describes how a month‐long visiting professorship from an academic with a clinical librarian background at the Faculty of Health and Life Sciences helped to develop and inform teaching practice in the areas of information literacy and evidence‐based health practice on health programmes at Pacific University. Perspectives are offered from both institutions on the rich exchange of knowledge and practice that took place during the visit and the ongoing impact it has had on teaching practices. H. S.  相似文献
