Abstract:

Laboratory teaching plays an irreplaceable role in cultivating the practical ability and scientific literacy of engineering students. Experimental preview is very important for students to form good laboratory habits and safety awareness. Based on the platform of "Wechat + Questionnaire star", this paper reformed the preview mode of university chemistry laboratory, introduced the concept of game breakthrough, and developed the online examination small program of breakthrough type preview of university chemistry laboratory, to replace the traditional paper preview thinking questions, and guide students to actively accept the challenge of breakthrough type. The practice achieved good teaching effect.
