传统的教学评估中,以终结性教学评估为主,主要以阶段纸笔考试为主要依据对学生进行评判,而忽略了学生学习态度、学习习惯等方面的考量。目前,学习等级代替考试分数,是基础教育的一大进步,然而,在小学数学的一线教学中,期待着更加科学、更关注学生学习动态的评估方法。形成性评估作为一种新型的评估模式,其评估对象是学生在教学活动中某一阶段中的全部内容,如学生的学习能力、学习策略、学习动机等,强调对学生学习过程的监控、 In the traditional teaching evaluation, the final teaching evaluation is mainly based on the stage paper pen test as the main basis for students to judge, while ignoring the student learning attitude, learning habits and other considerations. At present, the learning grade replaces the examination scores, which is a great progress in basic education. However, in the first-line teaching of primary mathematics, we look forward to a more scientific and pay more attention to the assessment of students’ learning dynamics. Formative assessment as a new assessment model, the assessment of the object is a student in teaching activities in a certain stage of the whole content, such as students’ learning ability, learning strategies, motivation to learn, emphasizing the monitoring of the learning process of students,
