超级画板应用在数学教学中,确实给教学带来了很大方便,不但提高教学效率,而且还可以通过动画演示来帮助学生理解很难想象的问题。尤其是超级画板应用到几何课的教学中,几何题的图形的变式,动画演示等不但形象直观,而且省去了黑板画图不标准、效率低等不必要的麻烦。笔者选择了几何课《相似三角形性质2》来说明超级画板在几何教学中的应用。由于本节课是初二的新授课,综合性不强,学生不是很难理解,就只是利用超级画板做了大量的变式图形,对于学生掌握重点、突破难点方面起了很大的帮助,高效完成本节课的教学目标及任务。
The application of super drawing board in mathematics teaching really brings great convenience to teaching, which not only improves the teaching efficiency but also helps the students to understand the hard to imagine problems through the animation demonstration. In particular, the application of super drawing board to the teaching of geometry class, the geometry of the graphic variations, animation presentations not only visual and intuitive, but also eliminates the need for blackboard drawing is not standardized, inefficient and unnecessary trouble. I chose the geometry class “similar to the nature of the triangle 2” to illustrate the use of super-board in the geometry of teaching. As this lesson is the second day of the new lectures, synthesis is not strong, the students are not difficult to understand, just make a large number of super drawing board variant graphics, for students to grasp the important breakthrough point has played a significant help, Efficient completion of this lesson’s teaching objectives and tasks.
