一、引言为理解而学习,成为当今学习和教学理论的一条重要信念,也是实施有效教学的一个重要策略.新课改已经历时十多年,课堂教学发生许多的变化,但长期以来,由于受应试教育的影响,不少数学教师重解题、轻概念生成,数学解题与概念脱节,学生对概念含混不清,一知半解,不能很好地理解和运用概念.数学课堂变成了教师进行学生解题技能培训的场所;而学生成了解题的机器,整天机械地按照老师灌输的“程序”进行简单的重复劳
I. INTRODUCTION Learning to understand has become an important belief in today’s learning and teaching theories and an important strategy for effective teaching. The new curriculum reform has been going on for more than ten years and many changes have taken place in classroom teaching. However, for a long time, The impact of exam-oriented education, many math teachers to solve the problem, the concept of light generation, mathematical problems and concepts out of touch, the concept of students ambiguous, little understood, can not properly understand and use the concept of mathematics classroom into a teacher for students Problem solving skills training places; and students to become a problem-solving machine, mechanically all day in accordance with the teacher instill “program ” for a simple duplication of work
