课本不仅提供了完整的知识体系,同时还提供了许多有价值的教育教学素材。例如,“万有引力定律”章节中有许多名人名言。如能引领学生挖掘其内涵,领悟其哲理,则会激发学生学习兴趣,培养他们的问题意识,更好地实现教学目标大有裨益。 Textbooks not only provide a complete knowledge system, but also provide many valuable teaching materials. For example, there are many famous quotes in the section entitled “Law of Gravitation.” If we can lead students to excavate its connotation and comprehend its philosophy, it will stimulate students’ interest in learning, cultivate their awareness of problems and achieve better teaching goals.
