在课堂上多媒体应用比比皆是——Powerpoint、Flash、Authware、几何画板等等的应用更是教师常用的工具,制作出来的课件形象、直观,学生也容易接受.但这些毕竟是我们预设的东西、人为制作的,离真实、现场的还是有距离,学生难免有疑虑——这是真实的吗?如果能把传统的教学中积累下来的现场演示与多媒体结合,做到信手拈来,这节课的效果会更好.而学生终身发展必备的物理基础知识和技能,能利用生活中的细线、杆、乒乓球等来演示一些物理现 In the classroom, multimedia applications abound - Powerpoint, Flash, Authware, Sketchpad, etc. applications are more commonly used tools for teachers, produced the image of the courseware, intuitive, students are also easy to accept. But these are our default Things that people make, from the real, the scene is still a distance, the students will inevitably have doubts - is this true? If you can traditional teaching accumulated in the live demonstration and multimedia, so come in handy, this lesson The effect will be better.And students essential lifelong physics basic knowledge and skills, can use the life of the thin line, pole, table tennis, etc. to demonstrate some physical
