High school chemistry classroom teaching of the use of multimedia Paper Keywords: high school chemistry; multi-media teaching Abstract: Multimedia in high school chemistry classroom teaching use of both forms of wealth, but also chemical reactions with cue and chemical laws. Through teaching, students to expand the horizons of knowledge, and stimulate interest in learning, improve classroom teaching efficiency. With the rapid development of information technology, multimedia applications in the field of education, the increasingly widespread. Chemistry is a basic natural science, which studies the material composition, structure, nature and variation. The use of multimedia teaching tools can enhance and deepen student interest in learning understanding of knowledge, to improve the efficiency of classroom teaching is very helpful. First, the media reinforce pre-class study Lectures before class research is the preparation of teaching, research only full before class, before getting on a high-quality classes, in order to achieve the desired teaching. The use of computer Jianghua before class research, assisted lesson preparation is a good way. For example, I prepared (ammoniagt;gt; this lesson, from the Internet to download the ammonia fountain experiment water-soluble analog animation, animated simulation of the molecular structure of ammonia, ammonia and acid reaction of the experimental simulation animation. And then these groups My pieces into the courseware, enriched my courseware, courseware that I have content, but also vivid. the most important lesson planning or greatly reducing the time, give full play to the role of resource sharing. so we can take full advantage of computers to compile chemistry teaching content and information, select or draw something useful for teaching chemistry classroom to enrich and improve the quality of pre-class study. Second, multi-media teaching process optimization Chemistry, a new lesson, no
