多媒体技术在中学化学教学中的运用越来越广泛,也日趋完善,使教学形式发生了极大的改变。而很多教师和学生对多媒体教学的积极作用还没有正确的认识,仅仅把多媒体作为文字承载的工具,没有很好地发挥多媒体教学的应有作用。事实上,多媒体教学能形象、生动和丰富地展示教学内容,激发学生的学习兴趣,提高学生分析问题的能力,极大地提高教学质量与效果。
The application of multimedia technology in chemistry teaching in middle schools is more and more widely used and has also been perfected day by day, making the teaching forms have undergone tremendous changes. However, many teachers and students do not have a correct understanding of the positive role of multimedia teaching. Just using multimedia as a text-bearing tool does not play a proper role in multimedia teaching. In fact, multimedia teaching can vividly and richly display teaching contents, stimulate students ’interest in learning, enhance students’ ability to analyze problems, and greatly improve teaching quality and effectiveness.
