数学新课程教学实践二三事——浅谈教学实践中教师的角色定位

According to the New Math Course Standard——a Talk on the Roles of a Teacher in Teaching Practice

在按照《全日制义务教育数学课程标准(实验稿)》实施教学实践的过程中,教师应注意:(1)教材中有的应用题可以给予学生充分的思维发展空间以及能力发展空间,教师应深入领会教材编者的匠心独运,在教学情境中,做好“导演”角色.(2)教材中有的问题提示,会在一定程度上束缚学生的思维发展,教师应创造性地使用教材,为了创设一个具有愉悦情感体验、渐进认知发展和突发创新思维的教学情境,认真编写好适合的教学“剧本”.(3)对于一些开放性的问题,教师不妨与学生一道充当“演员”,共同探究,但要敏锐地捕获学生的创新意识,记录“演员”的“华彩”篇章.

After reviewing these scenes with profundity, the author realized that: (1) Some application problems in the textbook were very helpful to students thinking development and talent building. A teacher should deeply understand the textbook compilers intension and act a good director role in the teaching situation. (2) Some hint in the textbook should restrict the development of students thinking to some extent. A teacher had to critically use the textbook and reorganize the teaching material as a scenarist rewrites a novel and set up such a teaching situation as to provide happy feeling experience, gradual knowledge development and creative thinking environment. (3) Sometimes a teacher had to play a role of an actor just as a student did in a teaching situation and made the research on some open problems with the students together.
