收集信息资料 设计新课导言

地理课导入的方法多种多样,故事导入、诗歌导入、教具导入等等,这些方法多具特色。笔者认为,如果教师收集一些与地理有关的信息资料,选择恰当新颖,具有趣味性、启发性、科学性的信息资料作为新课导言,可以起到“一石击破水冲天”的波动效果,下面试举几例。     

Nordic Geoscience and the 33rd International Geological Congress： Introduction

Geology has been of profound importance for the Nordic countries since the Middle Ages. Strong economies were built on an understanding of the occurrence in bedrock of minerals containing metals, e.g., silver, copper, zinc and iron, and eventually led to the establishment of the first Geological Surveys in Norway and Sweden in the middle of the nineteenth century. The geology of Norden ranges from the oldest to youngest rocks on the planet. Based on the papers in this special issue, this introduction provides a brief summary of the geological evolution of Norden, from the Archean of Greenland and northern Fennoscandia to the on-going volcanicity in Iceland on the MidAtlantic Ridge. It also refers to aspects of Geoscience that are particularly important for society in Norden, including geo-resources （petroleum, geothermal energy, nuclear energy, metals, industrial minerals and groundwater） and environmental geology （including natural and anthropogenic processes, medical geology, geo-hazards and climate）. Information on the early history of geology in Norden and the geological surveys is also included and, finally, an outline of the 33rd International Geological Congress with its main theme “Earth System Science： Foundation for Sustainable Development”.
