翻转课堂模式在光度法测铁实验教学中的应用

翻转课堂模式有助于使课堂教学从以教师为中心向以学生为中心转变,因而受到教育界广泛关注。以邻二氮菲分光光度法测定水中微量铁为例,探索了翻转课堂教学模式在非化学化工类大学化学实验教学中的应用。依据翻转课堂教学流程研究了课前视频、课前在线检测题及课上活动的设计与实施方案,探索了将科技文献用于课前视频的教学方法。利用课上活动给学生提供自我展示的机会;利用课前视频和课前在线检测使学生的课前预习落到实处、拓宽学生视野、激发学生对化学实验的兴趣。

The Application of Flipped Classroom Mode in the Experimental Teaching of Photometric Determination of Iron

The flipped classroom has drawn much attention because it facilitates the transition from a teacher-centered classroom to a student-centered classroom. Taking an experiment of the phenanthroline spectrophotometric determination of micro-iron in water, as an example, the paper explores the application of the flipped classroom teaching mode in college chemistry laboratory teaching for non-chemistry majors. According to the flipped classroom teaching process, this paper studies the instructional design and implementation of the pre-class video, the pre-class test and classroom activities in class. And it also explores the teaching method of the scientific and technological literature application of a pre-class video. Classroom activities provide students with the opportunity to present themselves. The pre-class video and the testing help students to prepare experiment, broaden the vision of students, and motivate students' interest in the chemistry experiment.
