化学是一门以实验为基础的自然科学,加强实验教学已经成为广大教师的共识,学生学习化学方法的掌握以及综合能力的提高,都要求化学教学必须重视实验,然而,学生在实验教学中的表现存在着巨大的差异,这种差异又影响到整个化学教学质量的提高,如果我们老师不重视学生在化学实验中的差异,一味地采取一刀切的方式进行教学,势必使部分学生的实验能力得不到更好的培养,要么使某些学生掌握不了实验,实验的能力没有得到培养,要么使某些优等生的潜力没有得到挖掘, Chemistry is an experiment-based natural science. Strengthening experimental teaching has become the consensus of the majority of teachers. The mastery of students’ learning chemistry methods and the improvement of comprehensive ability require that chemistry teaching must attach importance to experiments. However, students in experimental teaching There is a huge difference in performance, this difference also affects the quality of the entire chemistry teaching, if our teachers do not attach importance to the differences in chemistry experiments, blindly take a one-size-fits-all teaching, is bound to make some students experimental ability Less than a better training, either to make some students can not master the experiment, the experimental ability has not been trained, or some of the potential students have not been tapped,
