表扬与批评是对学生进行教育不可缺少的两种手段。要使表扬与批评收到良好的教育效果，必须坚持“表扬不过头，批评不失实”的原则。所谓“表扬不过头”，是指教师对学生进行表扬时，一定要依照事实，根据学生成绩、优点的大小，恰如其分地作正面肯定，让事实说话，使表扬达到 Praise and criticism are two indispensable means to educate students. In order for praise and criticism to receive good educational results, we must adhere to the principle of “praising each other and criticizing the truth.” The so-called “recognizes no head” means that when teachers praise the students, they must follow the facts and make positive recognitions based on the results and merits of the students. Let the facts speak so that praise can be achieved.
