传统数学教学由于强调预设和封闭,使教学缺乏生气和乐趣,压抑了学生的发展。而中小学生的兴趣正处于培育和发展的重要阶段,社会、学校和家庭应力求创造轻松和开放式的宽松环境鼓励与培养学生学习数学的兴趣,方能提高他们的学习积极性。 Due to the emphasis on presupposition and closure, the traditional mathematics teaching has made the teaching lacks anguish and fun and suppresses the development of students. The interests of primary and middle school students are at an important stage of nurturing and development. The society, schools and families should strive to create a relaxed and open environment to encourage and develop students’ interest in learning mathematics so as to enhance their enthusiasm for learning.
