摘要
实验是化学教学中十分重要的一部分,然而当下高职高专化学实验教学中存在实验课时数不充足、实验仪器不完善、安全隐患大、学生的实验基础水平不高等方面问题,为此将微视频教学应用到化学实验教学改革中,能够提高学生实验操作的规范性、便于学生进行课前课后学习,还可以利用微视频呈现特殊实验;通过滴定反应实验教学,细致阐述了微视频在化学实验教学中的应用。
Experiments are a very important part of chemistry teaching. However, in the current chemistry experiment teaching of higher vocational colleges, there are three problems: insuff icient experimental hours, imperfect experimental equipment, high safety risks, and low basic level of students’ experiments. Video teaching is applied to the reform of chemistry experiment teaching, which can improve the standardization of students’ experimental operation, facilitate students to study before and after class, and can also use micro-video to present special experiments. Through the titration reaction experiment teaching, the micro-video is explained in detailapplication in experimental teaching.
