笔者对贵刊2006年第6期刊载的“探索三角形全等的条件(第一课时)”的4个课例进行了深入地对比研读,感觉收获颇多,有精心预设也有精彩生成,很多地方值得借鉴学习.现就4个课例尝试着谈一些个人的看法.1 关于情境的设计4个课例都采用了生活情境导入的方式,按照“问题情境——建立模型——解释、应用与拓展”的模式展开教学,让学生经历知识的形成与应用过程,从而更好地理解数学知识的本质意义,掌握必要的基础知识和基本技能,发展应用数学知识的意识和能力.1.1 情境设计的开放度
The author of your magazine in 2006 No. 6 published “exploration triangle congruent conditions (first class hours)” four case studies conducted in-depth comparative study, I feel a lot of gains, there are meticulously well-prepared wonderful generation , Many places are worth learning for reference.Now four lesson plans to try to talk about some personal views.1 on the design of the context of four lessons are used to import life situation approach, in accordance with the “problem context - to establish a model - Interpretation, Application and Development ”to enable students to experience the formation and application of knowledge in order to better understand the essential meaning of mathematical knowledge, acquire the necessary basic knowledge and basic skills, and develop the awareness and ability to apply mathematical knowledge .1.1 the openness of contextual design
