生物教学中一些抽象、难于理解的知识点可以借助多媒体教学手段直观形象加以解决,我在课堂的应用主要表现在演示图片、知识结构、练习、及个别实验。支持我不懈尝试信息技术的还有一个原因即学生经多感官的刺激很容易做到突出课的重点、突破课的难点。 In biology teaching, some abstract and difficult to understand knowledge points can be solved with the help of the visual image of multimedia teaching methods. My application in the classroom is mainly in the demonstration pictures, knowledge structure, practice and individual experiments. Another reason that supports my tireless efforts in information technology is that it is easy for students to highlight the lesson’s focus and overcome the difficulty of the lesson by stimulating the senses.
