数学课堂教学中,有不少老师喜欢“指名板演”。这样做,板演学生可作巩固练习,也为教师提供反馈信息,以便教师及时评讲。但是,这种“指名板演”的反馈形式也有以下副作用。由于小学生的主动性和独立性还比较差,意志上也较薄弱,外部的影响在儿童的行为上起着重要的作用。因此,有些学生在练习中一旦发生困难,往往不能独立思考,而是依赖于板演的学生,练习缺乏独立性。久而久之,就会养成不良的学习习惯。 In mathematics classroom teaching, many teachers like to “name board play.” In doing so, boarding students can consolidate the practice, but also provide feedback information for teachers so that teachers can comment in time. However, this feedback form of “boardwalk” has the following side effects. As the primary school students' initiative and independence are still relatively poor and their will is weaker, the external influence plays an important role in children's behavior. Therefore, some students in the exercise of difficulties, often can not think independently, but rely on the performance of students, practice lack of independence. As time passes, it will develop poor learning habits.
