化学实验是学生学好化学的重要保障,培养学生的实验能力不仅关系到学生科学态度的培养,而且关系到学生的未来发展和全面发展。笔者在近几年的化学教学中发现,现在学生的化学实验能力存在着以下几方面的问题:一是不能正确使用常规仪器和药品,表现为操作不规范;化学试剂用量失控,多是进行过量操作。二是实验操作时不讲科学性、不按实验规则进行。表现为以习惯性动作代替科学性操作。三是不注重观察,只注重最终结 Chemistry experiment is an important guarantee for students to learn chemistry well. Developing student’s experimental ability not only concerns the cultivation of students ’scientific attitude, but also relates to the students’ future development and all-round development. In recent years, the author of chemistry teaching found that students now have the ability of chemical experiment in the following aspects: First, they can not properly use conventional instruments and pharmaceuticals, the performance of non-standard operation; chemical reagent out of control, mostly overdose operating. Second, the experimental operation does not speak of science, not according to experimental rules. The performance of habitual action instead of scientific operation. Third, do not pay attention to observation, only focus on the final knot
