随着现代教育技术的普及,多媒体课件已经频繁出现在数学课堂教学中。纵观当下课堂,多媒体课件的功用还只限于教师教学信息的传递,教学内容的快速呈现,教学思维的点拨启发,教学过程的跳跃推进。课件的来源可分为教师原创、加工、拿来三个层次,学生从不参与其中。换言之,制作、使用多媒体课件是教师的事,是从教的视角来思考的。如果我们认真研究多媒体课件的特点,重新认识多媒体,就会转换视角,最大限度地发挥其功用。
With the popularization of modern educational technology, multimedia courseware has appeared frequently in mathematics classroom teaching. Throughout the current classroom, the function of multimedia courseware is also limited to the transmission of teaching information, the rapid presentation of teaching content, inspirations inspired by teaching thinking, the teaching process to jump forward. Courseware can be divided into sources of teachers original, processing, brought three levels, students never participate. In other words, it is a teacher’s task to make and use multimedia courseware, which is to think from a teaching perspective. If we carefully study the characteristics of multimedia courseware, to re-understand the multimedia, it will switch perspective, to maximize its effectiveness.
