Stoichiometry Blues

This year's stoichiometry test has come and gone with less than thrilling results. We're okay on unit conversions, but when we add that extra step of using the balanced reaction to describe ratios between substances, things fall apart.

This is a tough concept that I struggle to teach well. I don't know if more labs/hands on will help - I added one this year and I didn't see better results. Granted, we had several weather interruptions last week that preceeded the test, but even today, there are still large gaps in understanding that I need to do some digging into to figure out what is going on. My hunch tells me that is a "will" issue instead of "skill" issue for 90% of students.
