随着教学改革的逐步深入发展,电子计算机作为先进的教育媒体和手段已进入中小学.在数学教学中充分地使用电子计算机,可以提高学生的学习兴趣,培养学生的能力,提高教学质量.多年来,我将电子计算机应用于数学教学,收到了较好的效果.1.利用动、静结合的直观演示,改革传统的教学方法以往在课堂上讲授函数图象时,教师在黑板上进行长时间地列表、描点、作图,耽误了不少教学时间.现在我使用电子计算机教学软件配合教学,既快又好,效果远远超过传统方法.例如在椭圆定义教学中,演示如下:
With the gradual deepening of the teaching reform, electronic computers have entered the primary and secondary schools as advanced educational media and means. Full use of electronic computers in mathematics teaching can increase students’ interest in learning, develop students’ abilities and improve teaching quality. In the past, I have applied computer to mathematics teaching and received good results. 1. Using the intuitive demonstration of combining dynamic and static, reforming traditional teaching methods. Teachers used to teach functional images in class. Time lists, sketches, and drawings have delayed a lot of teaching time. Now I use electronic computer teaching software to cooperate with teaching, which is fast and good, and the effect far exceeds traditional methods. For example, in elliptical definition teaching, the demonstration is as follows:
