在讲授“达尔文学说的发展”一节时,由于该章内容多系专门科学知识,所以在讲解时学生反映不易懂.又由于教者自己学识肤浅,直观教材缺如,往往收不到良好效果.兹将本人点滴备课经验,作一简单介绍,供教学工作上的参考. 首先在备课工作中要解决的是掌握直观教材,而有关古生物学方面的直观材料是不易取得的.本校校址所 When teaching “Development of Darwin’s Theory”, the content of this chapter is mostly composed of specialized scientific knowledge, so students’ reflections are not easy to understand when they explain them, and teachers often do not receive good results because of their superficial knowledge and lack of visual teaching materials I will make a point of lesson preparation experience for a brief introduction for reference on the teaching work.First lesson in lesson preparation is to master the visual materials, and the visual materials on paleontology is not easy to obtain.
