化学实验对全面提高学生的科学素养具有极为重要的作用,但在教学中往往受实验条件的限制,部分实验不能完全发挥其应有的教学作用,因此,利用多媒体辅助化学实验就成为必然。下面,笔者结合教学实践,就多媒体在化学实验教学中的作用和怎样用多媒体教学提出以下一孔之见。一、多媒体在化学实验教学中的作用1.能扩大演示实验的效果。对于有气体放出、产
Chemical experiments play an extremely important role in improving students’ scientific literacy. However, they are often limited by the experimental conditions in teaching. Some experiments can not fully play their due teaching role. Therefore, the use of multimedia-assisted chemical experiments becomes an inevitable result. The following, the author combines teaching practice, the role of multimedia in chemistry experiment teaching and how to use multimedia teaching to make the following humble opinion. First, the role of multimedia in chemistry experiment teaching 1. To expand the effectiveness of demonstration experiments. For gas release, production
