是学生能考高分就说明课堂效益高,还是应更多关注教师创设有效学习的环境与氛围,及对学生学习活动的指导和帮助——我们要什么样的课堂教学效益?笔者有幸观摩了我县七年级一堂数学课,课题是“同类项”。上课教师首先投影教学目标,接着投影若干单项式、多项式,以提问的方式进行复习,之后教师组织学生进行讨论。讨论的问题有二:一是上述多项式中哪些单项式可以归为一类;二是同一类的单项式的特征是什么。讨论刚一展开,教师即早早 Is the student can test the high score on the classroom shows high efficiency, or should pay more attention to teachers to create an effective learning environment and atmosphere, and to guide and help students learn activities - what kind of classroom teaching we want? I was fortunate enough to observe me County seventh grade math class, the subject is “similar items ”. Class teachers first projected teaching objectives, and then projection of a number of monomials, polynomials, to ask questions to review, after which teachers organize students to discuss. There are two issues for discussion: First, which of the above polynomials can be grouped together; second, what are the characteristics of the same type of monomials? As soon as the discussion started, teachers were early
