This an appeal for assistance. I'm writing a multiple-choice safety exam for undergraduate lab students. In this exam, I want to question the reasoning for the lab rules/safety practices, not just what the rules allow or forbid. I'm finding this fairly difficult, as I object to using false information as distracters (wrong answers). My solution, so far, has been to ask about priorities (which of these items should you do first?) and use questions where all choices are correct, but not all answer the question at hand What is the reason for prohibiting ALL chewing gum, food, drink, and smoking materials in the chemistry labs? Dried gum under lab benches Delay of lab work The possibility of contamination and poisoning No appropriate disposal containers Health concerns for those with food allergies If you have such questions - or ideas on how to approach this, please share your ideas with me. I will, of course, share the results with anyone who's interested. Let me know (off list). -- Sheila M.
