《数学课程标准》指出:现代信息技术的发展对数学教育的价值、目标、内容以及学与教的方式产生了重大的影响。由于多媒体课件以形象具体的“图、文、声、像”来创造教学的具体化情景,使抽象的教学内容具体化、清晰化,尤其是其交互性特点,使得课堂教学的组织更为紧凑,更能吸引学生的注意力,易于形成鲜明的表象,启发学生的思维,扩大信息量,教学效果也更为明显。因 Mathematical Curriculum Standards states that the development of modern information technology has had a significant impact on the value, goals, content and ways of learning and teaching mathematics education. As multimedia courseware to the concrete image of the “figure, text, sound, like” to create the teaching of the specific situation, the abstract teaching content specific, clear, especially its interactive features, making classroom teaching more organized For the compact, more able to attract the attention of students, easy to form a clear appearance, inspire students thinking, expand the amount of information, teaching effect is more obvious. because
