学生在思考数学问题时,因考虑不周全、思维不深入,缺乏反思和检验,常常出现一错再错的情况。而这种学习错误是一种来源于学习活动本身,直接反映学生学习情况的生成性的教学资源。作为新时代的教师,该如何变废为宝,有效利用学生的错误资源呢?主要从利用错误,激发兴趣;巧用错误,拓展思维和预设错误,以错促学三方面来进行探讨。
When students think about mathematics problems, they often go wrong once or twice because of inadequate consideration, lack of thinking, lack of reflection and test. And this kind of learning mistake is a kind of generative teaching resource that comes from the learning activity itself and directly reflects the students’ learning situation. As a teacher of a new era, how to make the best use of the erroneous resources of students? How to make good use of the wrong resources of the students? It is mainly to make use of mistakes, to stimulate their interests, to use mistakes, to expand their thinking, to make mistakes and to make mistakes.
