Abstract

This article describes the questionnaire by which the Austrian Ministry of Education investigated the state of media education in primary schools, and briefly summarizes the results. It then describes the teaching materials that have been and are being produced.  相似文献

Teaching approaches in higher education are at the general level well researched and have identified not only the two broad categories of content-focused and learning-focused approaches to teaching but also consonance and dissonance between the aspects of teaching. Consonance means that theoretically coherent teaching practices are employed, but dissonance occurs when two broad approaches are combined. Previous studies researched teaching approaches at the general level, whereas the present study, researched approaches to teaching at the course level. Three university teachers were interviewed in depth about their teaching approach to one particular course. Data were analyzed using qualitative content analysis. While previous studies have found that dissonance occurs between different aspects of teaching, this multi-case study revealed that dissonance can also be found within a single aspect. The present study suggests that neither content- nor learning-focused approaches to teaching are mutually exclusive and therefore may co-exist in individual teachers’ practices.  相似文献

Trotz hoher Studentinnen- und Absolventinnenzahlen in den meisten Studienrichtungen ist der Anteil der Frauen an akademischen Spitzenpositionen noch immer gering. Die Gründe für dieses Missverhältnis liegen in einer Reihe spezifischer Schwierigkeiten, mit denen Frauen bei universitären Laufbahnen konfrontiert sind. Die Politik der Europäischen Union verfolgt seit 1999 das explizite Ziel, Frauen stärker in der universitären und außeruniversitären Forschung zu verankern. Mit dem Vertrag von Amsterdam wurde auch der gemeinschaftsrechtliche Rahmen neu gestaltet. Das UG 2002 hat "Frauenförderung" und "Gleichstellung von Frauen und Männern" zur Aufgabe der Universitäten und damit zu einem zentralen Teil ihres Bildungsauftrags erklärt. Die Europäische Strategie des "Gender Mainstreaming" wurde so in eine innerstaatliche, alle Universitätsorgane bindende Verpflichtung umgesetzt. Der Beitrag behandelt die rechtlichen Möglichkeiten der vollrechtsfähigen Universitäten zur Frauenförderung und bewertet Reichweite und Wirksamkeit der neuen Rechtslage.  相似文献

There are signs that teams are becoming more popular in ethnographic research. New technology and, in the UK, the Research Assessment Exercise have facilitated the establishment and continuance of teams. In this paper, the authors discuss their experiences in one particular research team in recent years. Securing adequate funding has been the essential structural prerequisite. The authors distinguish among project, federated, and whole teams, depending on function and level of analysis. They consider team structure, approach, business, and processes, and the relationship between individual and team. Teamwork has enabled a wider and deeper coverage of work, a broader comparative base, and multiple researcher triangulation. The team provides a forum for the discussion of ethical issues, an immediate supportive reference group. It has opened up horizons, and promoted individual change and development. It has aided analysis and writing, and promoted clearer and more robust arguments. The article concludes with some caveats.  相似文献

Recent studies (Chiviacowsky & Wulf, 2002, 2005) have shown that learners prefer to receive feedback after they believe they had a "good" rather than "poor" trial. The present study followed up on this finding and examined whether learning would benefit if individuals received feedback after good relative to poor trials. Participants practiced a task that required them to throw beanbags at a target with their nondominant arm. Vision was prevented during and after the throws. All participants received knowledge of results (KR) on three trials in each 6-trial block. While one group (KR good) received KR for the three most effective trials in each block, another (KR poor) received feedback for the three least effective trials in each block. There were no group differences in practice. However the KR good group showed learning advantages on a delayed retention test (without KR). These results demonstrated that learning is facilitated if feedback is provided after good rather than poor trials. The findings are interpreted as evidence for a motivational function of feedback.  相似文献

Conventionally, isotachophoresis (ITP) is used for separation of ionic samples according to their electrophoretic mobilities. We demonstrate that the scope of ITP applications may be extended toward particle concentration and separation. Owing to the distributions of electrolyte concentration and electric field inside a transition zone between two electrolytes, a number of different forces act on a small particle. As far as possible, we provide estimates for the order of magnitude of these forces and analyze their scaling with the particle size and the electric-field strength. Furthermore, we experimentally demonstrate that polymer beads of 5 μm diameter dispersed in a high mobility “leading” electrolyte are picked up and carried along by an ITP transition zone which is formed with a low mobility “trailing” electrolyte. By studying the particle positions and trajectories, we show that impurities in the electrolytes play a significant role in the experiments. Additionally, it is experimentally shown that different types of beads can be separated at an ITP transition zone. In particular, beads of 1 μm diameter are not carried along with the transition zone, in contrast to the 5 μm beads. The presented technique thus adds to the portfolio of electrokinetic transport, concentration, and separation methods in microfluidics.  相似文献
