随着多媒体技术的突飞猛进,我们发现数学实验也已逐渐发展成为初中学生学习数学学科非常重要的方法和辅助手段。在课堂教学中教师不仅能指导学生用简易的数学器材在黑板上展示不同几何体的拼接及展开图,还能指导学生用多媒体演示图形的拆分组合以及翻折旋转等变化规律,让学生能够在实验中直观感知数学与图形间的联系,并能够逐步培养学生数形结合的思想。这就需要数学教师转变观念,有计划、有目的地利用生活中的素材开展数学实验,努力使自己从一
As multimedia technology advances by leaps and bounds, we find that mathematical experiments have also evolved into a very important method and aid for junior middle school students in learning mathematics. In classroom teaching, teachers not only can guide students to display the splicing and unfolding of different geometrical figures on the blackboard with simple math equipment, but also guide the students to use the multimedia to demonstrate the split pattern of the figures and the turning rules such as turning and turning, Experiment intuitively perceived the relationship between mathematics and graphics, and can gradually cultivate the idea of combining the number of students. This requires math teachers to change their mindset, use the material in their daily lives in a planned and purposeful way to carry out mathematical experiments and try to make themselves from one
