Thanks for your input - I'm trying to find a way to hammer in the importance of units in dimensional analysis without having to spend hours grading the quizzes.
So does the capital vs lower case differentiation only work for units that aren't words?
A student entered "Calories" as an answer when "calories" was the correct unit. The answer was marked as correct.
Hmmm, writing what is being measured. That makes sense in stoichiometry, but in previous quizzes I got tired of writing 12 different units (g of H2O, grams of H2O, g H2O, grams H2O, each with different numbers of spaces between each word or symbol) to catch all the different ways that students might write the answer. These are intro to chem (pre-college level) students, so things can get creative.
Thanks for the head's up on sulfur. I'll steer clear of atoms S.
I haven't run into any spacing oddities yet, which is a nice change.
Thanks again for your response, it gives me a clarity about how to adjust the questions.
