一、问题的发现从小黑板到多媒体课件,数学课经历了一次重要的变革,课件使用得当会让普通的数学课变得更生动有趣,使学生在一节课中学到更多的知识。几乎每节对外评优课或公开课都少不了课件的出现,课件的制作也日趋精良,设计更巧妙精彩,越来越多的数学老师能够娴熟地制作和使用课件进行教学。 First, the problem found From small blackboard to multimedia courseware, math class has undergone an important change, the courseware properly used to make ordinary math classes become more vivid and interesting, so that students learn more in a lesson. Almost every section of external evaluation or open class are indispensable to the emergence of courseware, courseware production is also increasingly sophisticated, more ingenious design, more and more math teachers can skillfully make and use courseware for teaching.
