一幅画要有留白处,才具有美感,否则画面的拥挤必然会使人出现审美疲劳。数学课堂教学亦是如此,教师要在适当的时间介入课堂留白,为学生的自主学习、思考以及灵动的形成提供充裕的时间。较之传统教学中快速而又高强度的填鸭式教学,这更能使学生积极思考,提高数学思维能力。由于是在时间、空间上都给学生留出了空白,使学生可以不受外界对思维的干涉,独立获得知识,更容易去记忆。另外,由于是学生自己掌握教师给予的这段空白,更容易根据自身情况来调节学习、思考的节奏,有效避免了因心 A painting should be left blank to have a sense of beauty, or the crowding of the screen will inevitably lead to aesthetic fatigue. Math classroom teaching is also true, teachers should intervene in the classroom at the right time, for the students to learn, think and smart to provide ample time. Compared with the fast and high-intensity cramming teaching in traditional teaching, this can make students think positively and improve their mathematical thinking ability. Because it is in time and space to give students a blank, so that students can not interfere with the outside world, independent access to knowledge, easier to remember. In addition, because it is the students to master the teacher to give this gap, more easily adjusted according to their own circumstances, learning and thinking of the rhythm, effectively avoiding the heart
