一、巧借信息技术的交互性,激发学生学习数学的兴趣和培养其创新思维能力人机交互性是多媒体计算机的显著特点,它能有效地激发学生的学习兴趣,使学生产生强烈的学习欲望,发挥学生的主体作用,从而提高学生的创新思维能力。如题组训练是数学课堂教学的一个重要环节,传统的方法是点几名学生(或自愿)到黑板上演算,完毕后教师再讲评,或者是教师"一块黑板、一支粉笔、 1. Skillful use of the interactive nature of information technology to stimulate students’ interest in learning mathematics and cultivate their innovative thinking. Human-computer interaction is a distinctive feature of multimedia computers. It can effectively stimulate students’ interest in learning and enable students to have a strong desire to learn. The students’ main role will be brought into play so as to improve students’ creative thinking skills. For example, group training is an important part of mathematics classroom teaching. The traditional method is to point a few students (or voluntarily) to the blackboard for calculations. After the completion, the teacher will give a comment, or the teacher “a blackboard, a chalk,
