摘　　要：以节约实验室资源和实验改进及时性这两方面为提高实验教学效果的出发点,采用关联和对比的方法,对两门化学类选修课的实验进行了改进。针对其中一门课设计了两个具有前后关联的实验,使前一个实验的成品能为后一个实验充分利用。再根据学科交叉的特点,将这门课的一个实验进行调整后运用到另一门选修课实验教学上。结果表明,在锻炼学生实验技能的同时,关联实验有效利用了实验产品和实验时间;对比实验有利于教师进行实验观察和研究,以便及时调整实验方案。因此,这种改进从学生、教师及实验室方面均体现了显著的效果,是一种值得尝试的实验室教学探索。With saving the laboratory resource and mending related experiments timely as the starting points of improving the experimental teaching, the experiments in two chemical electives are selected and adjusted by correlation and comparison methods. Two tandem experiments are designed in one course with the product of the former experiment as the raw material of the latter. Then according to the character of interdisciplinary trend, an experiment after mending in the course is used in another. The results show that apart from training students＇ experimental skills, the correlation method can use both products and time effectively, while the comparison method can provide convenience for teacher observation to adjust the experiment in time. So based on the improvement for students, teacher and laboratory, these changes are worth trying in experimental teaching exploitation.
