计算机辅助教学兴起以来,一个争论不休的问题是如何认识教育技术和教师的作用。近一两年,随着计算机技术的突飞猛进,这个问题更加突出了。尽管在理论上,不少文章对计算机在教学的优势进行了详尽的阐述,教育软件的智能化程度也有了长足的进步,然而一个不容回避的事实是,计算机对数学教育的影响并不大,计算机教育与数学教育还是严重脱节。广大数学教师和计算机之间仍存在着难以跨越的鸿沟,绝大多数的数学课依旧是粉笔加黑板的传统教学模式。本文以点到直线距离公式为例子,通过和学生一起设计开发一款能够自动计算点到直线距离的软件,来锻炼学生的计算机数学思维能力。
Since the rise of computer-assisted instruction, one of the most debated questions is how to recognize the role of educational technology and teachers. In the past year or two, this problem has become even more conspicuous with the rapid advance of computer technology. Although in theory, many articles have elaborated on the advantages of computer in teaching and the intellectualization of educational software has also made great strides. However, one unavoidable fact is that computers have little impact on mathematics education, Computer education and mathematics education is still a serious disconnect. There is still an immeasurable gap between the vast majority of mathematics teachers and computers. The vast majority of math classes are still the traditional teaching mode of chalk and blackboard. This paper takes the point-to-line distance formula as an example to train students’ mathematical thinking skills by designing and developing a software that can automatically calculate the distance from point to line.
