教师、学生、活动内容是构成数学实践活动的基本要素。因此,要实现数学实践活动目标,就需要教师、学生和活动内容这三个要素紧密配合、互相协调。然而在实际教学中,受教师数学教学观念、教师职能发挥的影响,学生数学学习信念、自主探究能力等的影响,活动内容选择的影响,往往会使活动效果大打折扣。 Teachers, students, activity content constitute the basic elements of mathematical practice. Therefore, in order to achieve the goal of mathematical practice, teachers, students and activities need to closely cooperate with the three elements and coordinate with each other. However, in the actual teaching, influenced by teachers’ mathematics teaching concept, the influence of teachers’ function, the students’ belief in math learning, self-exploration capability and the influence of the choice of activities, the effect of activities is often greatly reduced.
