主题图是新人教版数学教材的一大特色,但在实施过程中,往往由于教师对主题图认识的不深入,不能有效发挥其作用。教师若能好好利用主题图,做到课前认真解读,课中深刻把握,课堂将会焕发出新的光彩。 Thematic map is a major feature of the new teaching version of the mathematics textbooks, but in the implementation process, teachers often do not have an in-depth understanding of the topic map and can not effectively play their role. If teachers can make good use of the subject map, do a careful reading before class, a profound grasp of the class, the classroom will be full of new glory.
