新课程标准明确指出:学生学习数学的过程,就是活动积累的过程,让学生在数学活动过程中积累经验,从而提高学生的数学思维能力与素养。要帮助学生学会探索数学知识的能力,最有效的方法就是引导学生对所学的数学知识进行实验与操作。通过做实验激发学生的学习兴趣,让学生直观感知知识的形成过程,培养学生的动手操作能力和求实的科学态度。然而,在教学中进行实验时,我们往往顾此失彼,效果差强人意。在借助实验进行 The new curriculum standard clearly states: The process of students learning mathematics is the process of accumulation of activities, allowing students to accumulate experience in the process of mathematics activities, thereby enhancing students’ mathematical thinking ability and accomplishment. The most effective way to help students learn to explore the power of mathematical knowledge is to guide students to experiment and operate on the mathematical knowledge they have learned. Through experiments to stimulate students’ interest in learning so that students intuitively perceive the formation of knowledge, training students practical ability and realistic scientific attitude. However, when we conduct experiments in teaching, we tend to lose the other way and the effect is far from satisfactory. In the experiment
