Before a Lab Even Starts
Many safety-conscious faculty require students to pass a prelab quiz before starting any lab activity. The prelab quiz encourages students to understand laboratory and safety procedures before they even start. According to a recent survey, the number-one reason for accidents in the science lab was “students’ failure to carefully read and understand laboratory activity instructions.” A prelab quiz may help solve this problem.
