This study examined the similarities and differences in experienced secondary science teachers' planning, teaching, and reflecting on their teaching, when teaching in their science area of certification and when teaching in another science area. The study also focused on the influence of these teachers' content knowledge, pedagogical knowledge, and pedagogical content knowledge on their planning, teaching, and reflecting. Experienced teachers were observed and interviewed while teaching classes in their science area of certification, and in another science area they were teaching for the first or second time. Both similarities and differences in teaching were found in the two areas for all three teachers. For example, their planning and postlesson reflections were similar in both areas. In the interactive phase of teaching more differences were observed. Many aspects of their teaching resembled that of expert teachers in other studies. In the unfamiliar science area, the teachers sometimes acted like novice teachers. However, they were able to draw upon their pedagogical knowledge to provide a framework for their teaching in both science areas. Their wealth of pedagogical knowledge, and pedagogical content knowledge for general science topics, seemed to sustain them in whatever content they were teaching. Recommendations for further study and implications for teacher education are discussed. 相似文献
Current printed courses of the Open universiteit (Ou) have been designed according to a variety of course models; for example the ‘learning unit model’ or the ‘textbook‐workbook model’ (van den Boom & Schlusmans 1991). Considering the potential of the ILCE approach (Valcke & Martens, this issue), one can imagine new and innovative course models that build on the interactivity and flexibility possibilities of such an environment An essential feature of the ILCE approach is that developers can consider student differences when designing and producing learning materials.
In this article we will explore the problem of adapting the delivery of learning materials to student characteristics in relation to a course based on ‘cases’ in the law domain. Two different study modes are researched: a study mode that starts with the theory and next moves to practical work with the cases versus a study mode that starts with the practical work and next moves to the theoretical base.
Two studies are presented. Within the exploratory study, the research questions focus on the potential interrelations between student characteristics and the preference/choice for one of the two study modes. From the results can be concluded that almost all students from the Open universiteit prefer a theory‐based study mode, because they have a relatively large amount of experience with this study mode and because they find it a successful study mode.
In the second study, an experimental design is adopted with students studying in one of four different conditions: two study modes of printed learning materials and two study modes of interactive learning materials. In contrast with the exploratory study students clearly indicate a more diverse preference for certain study modes. Students also differ in their preference for the delivery mode. However the more traditional study and delivery mode (theory‐based and printed learning material) remains more popular. Again this might again be due to the greater experience students have with this approach. Only two student characteristics are significantly related to opting for the practice‐based study mode: the experience level with a study mode and one's prior knowledge with the subject matter. Comparable results were detected regarding the preferred delivery mode: students with little prior knowledge more readily prefer a printed book, probably because they have a better overview. 相似文献
This study examines crossover effects of adolescent substance misuse preventive interventions on academic success in college. It evaluates pathways of influence on college grades, via effects on school engagement, problem-solving skills, and substance misuse in high school. Data were collected as part of an Randomized Controlled Trial (RCT) evaluating a multicomponent intervention conducted in 28 school districts with middle school students. At age 19, study participants (N = 1,488) enrolled in college reported on college grades. The model fit the data, supporting hypothesized pathways of intervention impacts. Inclusion of a significant direct effect on college grades further improved model fit. Results support the potential for universal substance misuse preventive interventions delivered by community partnerships during middle school to yield effects on long-term academic success. 相似文献
Abstract Recent legislation embodies different concepts of education that are commonly driven by the market and financial considerations. The Local Management of Schools (LMS) part of the Education Reform Act (ERA) is very similar in concept to recent innovations in the structure of other local government services. The continuing financial incorporation of education within the local government framework has resulted in the education welfare tradition being eroded especially through compulsory competitive tendering. Policy alternatives might be considered that look at structures for education outside the specific education remit and that see schools as a site for broad local authority provision. 相似文献
This article examines management of the Freedom of Information Act and how Federal information policy changed during the eight years of the Reagan administration. The article analyzes the 1986 F.O.I.A. amendments and, particularly, the fee waiver provisions; examines the varying congressional and executive interpretations of these amendments; and considers the Reagan administration's skillful use of traditional managerial tools in new ways to shape its policy and implement its philosophy. 相似文献
Multicultural service learning (MSL) seeks to develop pre-service teachers’ capacities and commitment to teach diverse student populations. We use multiple regression analyses of survey data collected from 212 pre-service teachers engaged in 22 MSL sites to assess the effects of pre-service teachers’ social identities, MSL contexts, and university pedagogy on pre-service teachers’ awareness of cultural bias, understanding of social inequality, and commitment to teaching diverse students. We find that pedagogical engagement positively contributes to all three outcomes. Pre-service teacher’s social identities and MSL contextual factors, however, have variable effects. We explore the pedagogical and research implications of this multidimensionality. 相似文献
The article provides historical evidence suggesting that a substantial element in the explanation of the profusion of talented composers in the 18th century Habsburg empire was the fragmentation of the state into many near-independent states, each with its own court seeking entertainment and prestige through new musical offerings. The resulting profusion of jobs attracted people into the profession and provided hearings for their work. The article also examines the data on Mozart's finances and using a rough translation of 18th century Austrian currency into current dollars supports recent revisionist findings that, with the exception of several years, he was relatively well off. 相似文献
Access to government records is increasingly shifting to a nether world-governed neither by the FOIA and the Privacy Act, nor by an executive order on classification. Instead, new categories of records, labeled “sensitive but unclassified,” “for official use only,” or “critical infrastructure information,” are being created in a variety of agencies, and are governed by agency regulations. Statutory authority is found in a number of separate laws, such as the Homeland Security Act and the Aviation and Transportation Security Act. These categories can be assigned by agency officials, contractors, or those in the private sector who originated the records; many records categorized this way are not subject to appeal or review by agencies or the courts, or to any automatic “declassification” process that has applied to documents withheld under the FOIA or subject to classification. Trends toward increased secrecy at all levels of government have become sufficiently alarming that individuals across the political spectrum have begun to speak out, and members of the access community (e.g., newspaper editors and public interest groups) have formed coalitions to focus debate on the need to rethink the balance of access with privacy and records protection, and to lobby actively for reinstatement of principles of access that have governed records policy for the past 35 years. 相似文献
