行为主义心理学认为:学习就是行动的反馈。由此可见,全面、及时、准确的信息反馈是提高学习效率的重要因素。近年来,我市小学数学中心组成员重点围绕“提高数学课堂反馈有效性的教学策略”这一主题,进行了较长时间的研究,我们发现在目前的小学数学课堂反馈上还存在着以下问题:不全面,教师往往以课堂上个别学生的回答,替代全班学生的学习信息反馈;不及时,教师往往为了赶时间,仅反馈解题正确的信息,忽视对解题错误情况的信息反馈;不深入,教师往往仅反馈学生解题的结果,忽视解题思考过程的 Behavioral psychology that: learning is action feedback. Thus, comprehensive, timely and accurate feedback is an important factor to improve the learning efficiency. In recent years, members of our primary school mathematics center focus on the theme of “improving the teaching strategies of the effectiveness of feedback in math classrooms” for a long period of time, and we find that in the present primary school mathematics classroom feedback exists The following questions: not comprehensive, teachers tend to individual students in the classroom to answer the student information to replace the entire class of feedback; not in time, teachers are often in a hurry, just to answer the correct information to solve the problem, ignore the error information on the problem Feedback; not in-depth, teachers often only feedback the results of student problem solving, neglect problem solving thinking process
