MSTF July 8 Spider Webbing

July 9, 2009
I continue to develop the spider web analysis lab. I’m trying to make the lab “bullet proof” which means the lab is explained in detail. You should be about to hand the lab directions to the average student and have them proceed with very little help from the instructor. I will e-mail the lab to Estaban and Scott and have them make any corrections that need to be done. I have been trying to thank like a beginning chemistry student without making any assumptions about pre-learned knowledge. This is not easy because I have learned that most students have not developed analytical deduction (common sense) to a great extent at this point in their cognitive development. No matter how well I explain the lab in writing, I will need to demonstrate or model the procedure. I would like to let the student struggle a little bit but with a tight time table in the curriculum I cannot afford that luxury. The lab has a long procedure but that is better than a short procedure that leaves the student confused and frustrated. I have added various inclusions that I normally don’t have in the average lab. I’m hoping the added short report that is due before the lab can add to the gained knowledge. Having time to work on the lab in the afternoon is a great help.
