在第三届新教育实验会议上,“理想的课堂”环节中,听了夏青峰老师一节数学课,感触很深。夏老师由浅入深,由易到难,循序展现,把一个大问题分化成若干个小问题,分散难点,各个突破,化难为易,步步相扣,遵循知识的内在规律,让学生了解了“分数”定义的来龙去脉。学生在夏老师的牵引下,一步步地走进了快乐的数学殿堂。一堂课,老师思维敏捷,学生积极主动,师生互动明显,配合默契。但我认为夏老师对于课堂环节的完整性的注重远远超过了课堂即时生成的本身,以至于本课没能把学生的想象力引向深入。夏老师在“闯三关”时,出示例题:“露出的部分是整 In the third session of the new education experiment, “ideal class” session, listening to a section of math Xia Qingfeng math, deep feeling. Summer teacher from the shallows to the deepest, from easy to difficult, the orderly show, a large problem into a number of small problems, scattered difficulties, all breakthroughs, the difficulty of easy, step by step, follow the inherent laws of knowledge, so that students understand The “ins and outs” definition of the ins and outs. Under the guidance of summer teacher, the student step by step into the happy math hall. A lesson, the teacher quick thinking, active students, interaction between teachers and students clearly, with understanding. However, I think that Professor Xia paid more attention to the integrity of the class than the immediate class generated, so that this lesson failed to draw the students’ imagination further. Summer teacher “Chuang three off”, to produce examples: "The exposed part is whole
