Students training to become primary school teachers appear to have little awareness of the core concepts of geography (teaching). To ensure that future primary school teachers are able to develop their pupils’ geographical awareness, a six weeks programme was developed. The characteristics of this programme – named Consciously Teaching Geography (CTG) – are: principles of good geography teaching, conjunction and a recurrent structure during training, modelling and reflection. In a quasi-experimental research design the question is answered what the effects are of CTG on the development of pedagogical content knowledge (PCK) for the subject of geography of first year primary student teachers. The results indicated that the programme has a positive effect on the domain-specific PCK development in the short term. 相似文献

Producer Services, Economic Geography, and Services Tradability 总被引:3,自引:0,他引:3
We investigate how the incorporation of producer services linkages affects the outcome of an economic geography model. We specify the production of manufactures such that a variety of producer services is needed to transform tradable unfinished goods into final consumption goods. We find that service linkages promote the concentration of economic activity in a single region, but whether full concentration is achieved depends on the costs and mode of services trade. Applying the model to a multiregion world shows that incorporating producer services may also give rise to regions that specialize in different economic activities. 相似文献

X-ray powder diffraction (XRD) analysis of clays from anthropogenic Late Holocene reservoir sediments can provide a paleoclimatic proxy. Illite and smectite are climate sensitive clay minerals and their relative amounts correlate with climatic episodes. Relative percent composition of clays in Late Holocene reservoir sediment is diagnostic of different mineral source areas and their hydraulic transport processes, which are climate controlled. Climosequences of clay minerals from Late Holocene reservoir sediments are correlative with magnetic susceptibility records and provide a relatively simple and cost-effective tool for gaining insight into paleoclimate. 相似文献
