在以往的教学中,教师通常根据经验、现象或是孤立的某些数字定性地判断学生群体对某一知识的掌握情况,无疑这样的判断难以做到精准。如今,我们可以借助大量的数据,更加准确量化地了解学生群体的水平,在教育走向实证的道路上向前迈出一大步。课前在备课过程中,对以下这些问题的判断将极大地影响我们的课堂效率,比如:哪些知识学生已经掌握,哪些知识是学生自己能够学懂的?在物理课堂上,哪些物理概念、规律、定理等需要我们重点讲
In previous teaching, teachers usually judge the students’ knowledge of a certain knowledge qualitatively based on the experience, the phenomenon or the isolated numbers, which is doubtlessly difficult to be precise. Today, we can take a large amount of data to get a more accurate and quantitative understanding of the student population and take a big step forward in the direction of education toward evidence. Pre-class preparation process, the judgment of the following questions will greatly affect the efficiency of our classroom, such as: What knowledge students have mastered, what knowledge is the students themselves can learn? What physical concepts in the physical classroom, the law Theorems need us to focus on
