IT技术的迅速发展带动了社会生活方式的变革,也对教育教学产生了深远的影响。多媒体辅助教学综合运用了声、光、音像等手段,使得以实验为基础的化学学科充满了吸引力,尤其是在化学实验课中,运用多媒体辅助教学手段可以再现不易觉察的实验现象,或者将不适宜通过现场操作的实验通过模拟实验逼真地呈现给学生,帮助学生理解实验原理和观察实验现象,从而激发学生学习化学的兴趣,进而促进学生自主学习能力的发展。因而,多媒体辅助教学优化了化学课堂,给化学 The rapid development of IT technology has led to changes in social lifestyles and has had a profound impact on education and teaching. The multimedia assisted teaching comprehensively uses the means of sound, light and audiovisual, which makes the experiment-based chemistry subject full of attraction. Especially in the chemistry experiment class, multimedia assisted teaching can reproduce the imperceptible experiment phenomenon, Experiments that are not suitable for on-site operation are vividly presented to students through simulation experiments to help students understand the experimental principle and observe the experimental phenomena, thus stimulating students ’interest in learning chemistry and then promoting the development of students’ autonomous learning ability. Thus, multimedia assisted instruction optimizes the chemistry class to chemistry
