That's a very good question. California, or at least our district, does focus on Learning Objectives, but not the actual SLO model. I had to actually look up exactly how to even format one. To answer your question, I think it is definitely something that can be checked upon throughout the year, as computer science is full of problem solving and the input/output/storing/processing model is needed any time a program is being coded. I also think it can be a stand alone, I am just at a loss for figuring out what kind of pretest to give to determine exactly where students are with the problem solving process and the model. That is something I think I will chew on for awhile, and maybe come up with a similar test I can give at the end of the year to see how students do after an entire year of problem solving in my class and others.
