形成性评价是评价学生学习成果和业绩的主要方法,也是保证教学质量的有效手段,更是教学活动的有机组成部分。形成性评价能够让学生认识自我,改变自我,提升自我。农村中学的学生大多是留守孩子,来自老师的评价对他们有至关重要的意义,不能用终结性评价对其做出不利于孩子成长的评价。 Formative evaluation is the main method to evaluate students’ learning achievements and performance, and is also an effective means to ensure the quality of teaching. It is also an integral part of teaching activities. Formative assessment enables students to recognize themselves, change themselves and enhance themselves. Most of the students in rural middle schools are left behind by their children. The evaluation from teachers is of great significance to them and can not be evaluated by terminal evaluation which is unfavorable to children’s growth.
