亚洲与欧洲地形教案

亚洲与欧洲地形教案 《亚洲与欧洲的地形》教学 惠农中学 张红玲 一、 设计思想: 本节课的教学内容根据课标和教学建议的要求，在教师的帮助下，学生自主学习亚洲的地形特征，并由此掌握分析大洲地形特征的，进而引导学生运用这些学习方法来学习欧洲地形的特点。在掌握知识的同时，培养学生对地理学科的兴趣，掌握一定的学习方法，增强学生的自学能力。因此，在设计时，首先要真正发挥学生的主体地位和教师的主导地位，坚定不移地开展自主学习，鼓励学生积极参与探究发现。 其次，在课堂教学中严格按照“先老师引方法，再学生用方法”的思路展开教学活动。 最后，为了很好地完成教学，努力做好以下几方面: 1、自主合作学习。通过创设积极的教学情境和学习氛围，引导学生认真讨论、合作、交流、探究、总结和归纳等方法来完成学习。 2、以地图教学贯穿始末。教学内容的每一个环节都引导学生读图、用图，析图、辩图、比图的方法，据图总结、依图问答，充分体现地图在地理课中的重要性，通过提高学生读图、析图能力，建立地理空间分析概念，培养空间思维能力。 3、运用多样的、灵活发的小标题设为教学的小环节，引导学生来完成学习的内容，以达到良好的教学效果。如“想一想”、“做一做”、“比一比”、“归纳”、“考考你”等活动环节的设计，开展containing gross errors, should immediately test if determined when monitoring data contain a large systematic errors, you should analyze ... 10.9.1 10.9 quality inspection and acceptance monitoring of equipment inspection and delivery inspection all our procurement monitoring equipment shall be as provided in section 10.2 of the terms of this technology, inspection and acceptance of delivery, and should include monitoring equipment factory inspection and test reports and delivery acceptance, acceptance certificate information supervising people. 10.9.2 monitoring instruments installed inbuilt quality check each measuring point measuring instruments and equipment after completion of installation, Embedment, immediately to inspect and test the quality of equipment installation, Embedment, and confirmed by the supervisor to check the quality before being allowed to begin monitoring contract work. Section 10.10 of completion on completion of each observation all monitoring equipment installed after laying, of 52nd of the references to this agreement the terms of the contract provisions, apply to the supervisor to monitor the project's acceptance of special, and according to the technical provisions 16.1. the 自主合作的探究学习，并得出结论的方法，之后学以致用地去学习和理解欧洲地形特点，交给了学生学习的多种方法，留给学生选择自己喜欢的方法去学习的空间，充分调动学生学习的积极性和创造性。 4、课内外延伸。课前要求学生收集相关图片，课堂上大量展示，课后鼓励学生多联系和运用课堂所学知识，提高收集资料的能力扩大知识面，认识到地理不仅有用，而且有趣。 二、教材分析: 本节课是在学生学习了亚洲与欧洲地理位置的基础上，进一步学习欧洲地形。本节课所涉及到的内容是“运用地图和相关资料归纳某一大洲的地形、气候、河流特点及其相互关系。”通过本节课的学习不仅为下面学习亚洲与欧洲的有关知识打下基础，也为后面有关区域地理的学习做好铺垫。重点是要引导好学生学会知识，掌握方法，学以致用。同时，还要培养学生读图能力和用图能力、分析问题和解决问题的能力，以及从各种资料中提取相关地理信息的能力。 三、学情分析: 七年级的学生由于年龄特点和认知特点的缘故，学生有较强的好奇心与求知欲，具备一定的自学能力;掌握了有关地图的基本知识;能自己收集相关的资料图片，具有一定的观察、比较、分析、归纳、推理能力;会读地图，已经掌握了大洲大洋及各种地形地貌的基本概念。而且上一学期《世界的地形》一节中已学过有关地形基础知识，对于地形和地势知识的理解有了一定的基础，上课前简单地做以复习提问即可。学生学习地理的积极性很高，因此本节课的教学设计重在containing gross errors, should immediately test if determined when monitoring data contain a large systematic errors, you should analyze ... 10.9.1 10.9 quality inspection and acceptance monitoring of equipment inspection and delivery inspection all our procurement monitoring equipment shall be as provided in section 10.2 of the terms of this technology, inspection and acceptance of delivery, and should include monitoring equipment factory inspection and test reports and delivery acceptance, acceptance certificate information supervising people. 10.9.2 monitoring instruments installed inbuilt quality check each measuring point measuring instruments and equipment after completion of installation, Embedment, immediately to inspect and test the quality of equipment installation, Embedment, and confirmed by the supervisor to check the quality before being allowed to begin monitoring contract work.
