摘要:

设计并实践了新的分析化学实验教学方法和考评方法。将案例分析与翻转课堂相结合,进行线上线下混合式教学。课前教师选择案例并设计问题,学生分组预习;课堂上学生讨论分析为主,教师查漏补缺为辅;课后学生撰写报告上传至线上平台,教师批阅并反馈问题。新的考评方法中,突出对学生表达能力、逻辑思维能力、团队协作能力、实验操作水平、实验台与实验室整洁水平的考查评价。实践表明,新的教学方法有助于提升学生的表达能力和实验操作水平,激发学生学习的积极性和挑战高难度学习任务的热情。新的考评方法为评价学生能力提供了可执行的标准。

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.

Key words: Analytical chemistry laboratory, Case analysis, Flipped class, Blended teaching, Evaluation method
