2、上,师生各有己见。但阅读的目的就是培养阅读策略，培养语感，特别是培养学生在阅读的过程中获取和处理信息的能力。在这个过程中教师起着鼓励，启发，引导，帮助，监控，参与，反馈与评价的作用二、学情分析我所带的学生英语基础较差，在阅读的基本能力方面学生的猜词义，推理判断能力较差。基于此在有限的课堂教学中，着重培养这方面能力和给予学生启发和思考是教师的第一要务。 本节课vocabulary为其内容之一，活动2，3均为词义理解的练习，但学生多习惯于学之前先学习词汇，这也是降低阅读难度的策略，但学生会减少在文中根据语境理解词义的机会，为此可以把这两个活动改为通过语境加深理解词义，掌握运用生词的活动。课前预习，

20、反思 1.在通过教师设问，学生思考回答从而完成学生知识点的自我积累时，我感到设问的问题较少，而在确定的几个主要问题上，学生回答较为准确，从而缺少了学生深入的思考与学习方法的体验。在对文章大意归纳时，给学生时间不足，从而缺少学生根据文章信息得出大意事的充分思考。在训练学生对信息加工与处理能力时，活动设计目的明确，但量不足，所获得的体验未能的到再体验与提高。2.用自己的话去完成对课文的复述这个练习教学中发现并不是学生的难点，这是因为空设计的太简单。而对学生自我能力的培养上，本节课起到了方法的指导作用。3.教学方法设计合理，运用恰当。但感到方法上缺少新意。在本堂课的教学理念上做到了面向全体学生，评价做到了注重发展性评价。但在教学设计中未能体现出来。九、板书设计Module4
