《数学课程标准》指出,数学教学是数学活动的教学,是师生之间、学生之间交往互动与共同发展的过程。“交注”“、互动”以崭新的姿态出现在我们的面前,引起了大家的关注。回顾以往的数学教学,很大程度还是灌输——接受,学生基本上是听讲——记忆——练习——再现教师传授知识。 The “Mathematics Curriculum Standards” pointed out that mathematics teaching is the teaching of mathematics activities and is the process of interaction and mutual development between teachers and students and between students. “Interaction” and “interaction” have emerged in front of us with a brand-new attitude, which has attracted everyone’s attention. Looking back on previous mathematics teaching, it is still largely indoctrinated—accepting that students basically listen—memorize—exercise—represent teacher’s imparting knowledge.
