Abstract:

We designed and practiced a new teaching and evaluation method in analytical chemistry laboratory teaching. By combing case analysis with flipped classroom, the courses were finished via mixed avenue of online and offline. Before class, teachers selected cases and raised series of questions, while students studied related contents in-teams. In class, students discussed the cases and questions, and teachers checked and made up for deficiencies. After class, students wrote and uploaded their reports, and teachers corrected errors in the reports. The new method evaluated the expressiveness, logical thinking, teamwork, experimental operation and cleanliness of bench and the lab. The practice of the new teaching method helps to improve the performance of students in expressiveness and lab skills, as well as to inspire the passion for leaning and taking challenging tasks. The evaluation method provided feasible criteria for evaluating the ability of students.
