Is there a clinical diagnosis for depression resulting from grading algebra exams?  There should be.  Over the course of the last few days I finished grading all of my algebra exams that I gave last week.  I have to say that I am utterly disappointed by some of the results.  It really has been one of the worst first exams that I have had the opportunity to grade over the course of the last 6 years.  I want to take some of the responsibility for their poor performance but there was just a huge lack of basic skill presented in their papers. 

I continually harp on the need to interpret your answers back into the context of a real world problem and ask whether or not the answer even makes reasonable sense.  I was just speechless when I saw the answers:

….How fast was the car going in the mountainous region?  Answer: 533 miles per hour
….How many quarts of paint will it take to paint a room with a perimeter of 70 feet and a height of 6 feet?  Answer: 1426 quarts.

Are you kidding me?
