分析化学教材中的实验,仅要求学生按规定的实验步骤,进行分析测定。这种实验是看方拿药式的验证性实验,对提高学生的实验能力是有限的。同时,理论课所讲授的理论及其计算,学生只能通过完成书后习题来巩固,致使学生对所学理论及其计算,既不知道怎么用,也没有机会用,造成理论课教学和实验课教学的严重脱节。针对这种情况,在理论课教学和实验课教学中间,适当增加设计实验方案的教学环节,是非常必要的。它可以使目前以单纯验证式实验为内容的实验课,逐步过渡到验证式和研究式相结合的实验课。
Analytical chemistry textbooks in the experiment, only require students according to the provisions of the experimental steps for analysis and determination. This kind of experiment is to take a prescription-based confirmatory experiment, which is limited to improve students’ experimental ability. At the same time, theories taught in theory classes and their calculations, students can only consolidate through the completion of book exercises, resulting in the theory and calculation of the students do not know how to use, there is no opportunity to use, resulting in theoretical teaching and experimental class Serious disconnect from teaching. In view of this situation, it is very necessary to appropriately increase the teaching links for designing experimental programs in the teaching of theoretical courses and experimental courses. It can make the present experimental course with simple verification experiment as the content, and gradually make the transition to the experimental course combining verification and research.
