齿轮传动是职业中学机械基础课程中比较重要的一个章节,并在实际生产中发挥着重大的作用。笔者曾多次尝试利用学生的动手能力并结合多媒体课件的直观性来拓宽学生思维的教学方法。实践证明这非常有效地突出本课程的教学重点:齿轮的工作原理、结构特点和适用场合;同时突破了本节课的教学难点:齿轮的应用特点。
Gear drive is a relatively important chapter in the basic mechanics of vocational schools and plays a significant role in actual production. I have tried many times to make use of the practical ability of students and combine the intuitiveness of multimedia courseware to broaden the teaching methods of students’ thinking. Practice has proved that this is very effective in highlighting the teaching focus of this course: the working principle of gears, structural features and application occasions; at the same time breaking the teaching difficulty of this lesson: the application characteristics of gears.
