-
摘要:拓展式教学对激发学生兴趣,扩展学生知识,提升学生解决问题的能力有极其重要的意义. 为此,文章结合汞光谱色散实验从知识拓展、思维拓展和生活拓展三个方面探讨了在物理实验中贯彻拓展式教学的方式方法.Abstract:Expansive teaching is of great significance inarousing students’ interest, expandingtheir knowledge and improvingtheir problem-solving ability. Based on a case study of spectral dispersion of mercury, this paper introduced how expan- sive teaching can be implemented in physics experiment through expansion of knowledge, thinking and living.
