一、确定性 在批改学生的数学作业时,必须逐题准确无误地使用“√”或“×”符号进行评定判断,切不可模棱两可,似对非对。符号不清或只简单地在作业后写上“查”或“阅”等字而不作具体的批改,会使学生弄不清到底对不对?也因此使他们失去了了解自己学习效率的“反馈源”。 二、指向性 批改作业不但要准确地使用“√”或“×”,对学生的作业作出评判,而且要帮助其找出错误原因,哪步错就 First, the certainty In the correction of students' math homework, you must use the “√” or “×” symbol by question to judge the judgment question by case, without any ambiguity, it seems right and wrong. The unclear sign or simply writing the word “check” or “read” after the assignment without making any specific changes will make it impossible for students to find out exactly what is wrong with each other, thus losing their “feedback” about learning efficiency source“. Second, the directional correction of homework not only to accurately use the ”√“ or ”×" to judge the operation of students, but also to help them find the cause of the error, which step is wrong
