多媒体教学手段在教育领域采已被广泛应用,特别是在一般的知识学习课堂教学中,多媒体对课堂教学效果起到很大的辅助作用。高中生物的操作实验多,并且难度相对较大,而普通中学生的实验技能较低,根据夸美纽斯教育原则、布鲁纳认知结构观点和奥苏伯尔学习理论,利用多媒体手段,增强直观性,能提高学生的接受性,帮助学生利用原有的认知结构进行同化,从而提升实验操作的成功性,提高生物实验课的效果。
Multimedia teaching has been widely used in the field of education, especially in the general knowledge-based learning classroom teaching, multimedia plays a great supporting role in classroom teaching. The experiment of high school biology is more and more difficult, and the experimental skills of ordinary middle school students are lower. Based on the Comenius education principle, Bruner’s cognitive structure and Ausubel’s learning theory, multimedia is used to enhance Intuitive, can improve the acceptability of students to help students use the original cognitive structure for assimilation, thereby enhancing the success of experimental operation, improve the effectiveness of biological experiment class.
