以数学问题为研究对象的问题解决,是新课标数学课程的一个重要内容。它不仅发展学生的创造性思维,也提高学生应用数学的意识,因此成为了数学教学研究的焦点之一。在问题解决教学方面,笔者长期思考和探索实践的几个主要问题是:尝试,是找准学生知识生成点,实施高效教学的法宝。怎样激励学生乐于尝试呢?怎样激发学生高度投入合作学习,并能在合作过程中实现自发互助?
Solve the problem of mathematical problems as the object of study, is an important part of the new curriculum mathematics curriculum. It not only develops students ’creative thinking, but also enhances students’ awareness of applied mathematics. Therefore, it becomes one of the focuses of mathematics teaching research. In problem-solving teaching, the author of the long-term thinking and exploration practice of several major problems are: try to find out the students knowledge generation point, the magic weapon to implement efficient teaching. How to motivate students willing to try? How to stimulate students to invest highly in cooperative learning, and in the process of cooperation to achieve spontaneous mutual assistance?
