Abstract:

In order to solve the frequently encountered problems on the experiment of extraction, refining and identification of Rutin in the laboratory class, new methods of teaching design and experiment process were adopted to suit different experimental procedure. With the improvement, both the success rate and the students' confidence were improved. The innovation experiment also illustrated the importance of process improvement to improve the quality of the products. Through the mutual improvement of teaching and learning in this experiment, teachers and students achieved the goal of learning together.
