《新课程标准》指出:“评价应关注学生是否有反思自己思考过程的意识。”在数学学习中,反思是发现的源泉,是训练思维的好方法。一在知识形成后反思:由感知走向体验教师在解决了一个或几个问题后,启发学生反思,对新的数学思想、策略进行总结和概括,这样学生就能将对“策略”的再认识转化成一个学习提升的过程,能很好地提高学生分析、解决问题的能力。案例1:倒推的策略比如,教学五年级(下册)倒推的策略练一练中,教师 The New Curriculum Criteria states: “Evaluation should focus on whether students reflect on their own thinking processes.” Reflexivity is the source of discovery in mathematical learning and a good way to train thinking. A reflection on the formation of knowledge: from perception to experience Teachers solve one or several problems, inspire students to reflect on the new mathematical ideas and strategies summarized and summarized, so that students will be able to Re-understanding into a process of learning and upgrading, can well improve students ability to analyze and solve problems. Case 1: Reversal Strategy For example, the teaching of fifth grade (Volume II) strategy to practice a practice, the teacher
