小学数学课堂教学中,教师需要时时观察学生的一言一行,从学生的表情、语言、眼神等变化上判断学生接受课堂信息指数情况。学生的神情变化,就是课堂教学中的“红绿灯”。学生学习顺畅时,其神态是充盈的积极的,“绿灯”打开,教师可以放心地施教;而学生学习受阻时,自然给教师传递多种困惑信息,“红灯”亮起,教师需要注意暂停教学进程,找到学生学习中存在的桎梏问题,采取针对性措施加以施救,为学生解除困惑。
In primary school mathematics classroom teaching, teachers need to observe students’ words and deeds from time to time and judge students’ acceptance of classroom information index from changes of students’ expression, language and eyes. Students look changed, that is, classroom teaching “traffic lights ”. When the student learns smoothly, his demeanor is positive and full, and the “green light” is on. Teachers can teach with confidence. However, when the students are learning to block, they naturally send confusing messages to the teacher, and the “red light” lights up , Teachers need to pay attention to the suspension of teaching process, to find the existing problems in student learning, take targeted measures to be rescued, to relieve confusion for students.
