随着多媒体技术的飞速发展,计算机辅助教学已成为数学教学的必然趋势,多媒体技术作为一种有效的辅助教学手段,已在不少数学课堂教学中产生了积极的作用。多媒体教学集声音、图像、视频和文字等媒体为一体,能产生生动活泼的效果,有助于提高学生学习的兴趣和记忆能力;同时,充分利用多媒体的表现力、参与性、重视力和受控性强的特点,既能达到传授知识、开发智力、培养能力又能实现因材施教和个别化教学的目的。然而在教学实践中,有许多教师对多媒体的认识仍不够清楚,
With the rapid development of multimedia technology, computer-assisted instruction has become an inevitable trend of mathematics teaching. As an effective auxiliary teaching method, multimedia technology has played an active role in many mathematics classroom teaching. Multimedia teaching integrates media such as sound, images, video and text, which can produce lively and lively effects, help students to improve their interest in learning and memory; at the same time, make full use of the expressiveness, participation, attention, and acceptance of multimedia. The characteristics of strong control can not only achieve the purpose of imparting knowledge, developing intelligence, cultivating ability but also teaching students in accordance with their aptitude and individualized teaching.
