2、第23课，前三个单元分别谈论了天气与活动、植物及种植、动物及保护，本单元谈论网络及使用。网络是比较时尚的话题，也是与孩子密切相关的话题，所以孩子们比较感兴趣，这也激发了学生们开口说英语的欲望。本课是学生在了解了电脑的发展与用途之后，继续谈论电脑的利与弊，老师要引导孩子正确使用网络，学生要能写出关于网络利与弊的小议论文。所以说本课是前四课的升华，是本单元的重中之重。 学 情分 析（分析学生已有认知水平、能力状况、存在的学习问题、学习需要和学习行为。）八年级的学生已经具备了一定的语言基础和一定的语言分析能力，也具备了对所学内容进行整理归纳的能力，能用简单的语言描述自己或他人。但在表达能力方面，八年

13、disadvantagestake up(1)开始从事（2）占有，占用教学反思本节课内容学习已经结束，现在我们通过测验来检测同学们的学习效果。本课以素质教育为目的，结合教材重点、难点及英语学科特点，利用任务型教学，从听、说、读、写等方面使学生得到锻炼，在愉快、轻松的氛围中温故而知新，达到初步运用英语交际的能力。我认为本课的不足之处是知识点的巩固练习还不够充分。课下还应多做这方面的练习，以继续巩固所学内容。在教学结构设计中可体现下列6个原则：1.突出学生的主体地位。2.从学生的问题出发营造教学情境，设计教学问题并引导学生探究、解决问题。3.设计出以任务型教学指导下的师生互动方式。4.争取准备两、三种针对不同群体学生的教学安排。5.对教材内容作适当的处理，发掘出教材内容之间的内在逻辑联系及育人作用。6.课堂教学要减少统一讲解，增加学生的自主探究，增加学生的分组活动。
