我制作的《用单摆测定重力加速度》Flash 动画课件(荣获2006年全国中小学多媒体信息技术教学实践与创新决赛二等奖),通过大屏幕投影仪展示,向学生进行方法指导和难点辅导,实践证明这种方法省时高效,能突出重点化解难点,教学效果良好,现介绍制作过程,供同行参考.1.创建素材(1)创建静态图形:在第1～6帧创建铁架台和控制底版图形.(2)创建输入文本:在第1帧创建摆球质量 m 和单摆摆长 L 文本框.(3)创建电影剪辑:①在第1～6帧创建摆球摆线DB 和可拖摆球 TD;②在第2～3帧创建刻度直尺 ZC 和滑移测量 HY;③在第4～6帧创建电子秒表 MB.(4)创建控制按
I produced the “single-pendulum gravitational acceleration” Flash animation courseware (won the 2006 primary and secondary multimedia information technology teaching practice and innovation finals second prize), through the big-screen projector display to the students guidance and difficult guidance, Practice has proved that this method is time-saving and efficient, can highlight the key to resolve difficulties, good teaching effect, is to introduce the production process for peer reference .1 to create the material (1) to create static graphics: (2) Create input text: Create the mass m and the pendulum length L text box in frame 1. (3) Create the movie clip: (1) Create the pendulum cycloid DB in the 1st to 6th frames Drag the ball drag TD; ② in the first 2 ~ 3 to create scale ruler ZC and slip measurement HY; ③ in the first 4 to 6 to create electronic stopwatch MB. (4) to create a control press
