Er, yes. You might need to restrict what you mean by 'programming' ..... I regard using spreadsheets as programming. But Scratch is very good at its job, to be sure.
I take it then that you're trying to out-do Scratch.
Does this sound reasonable?
Yes, it's probably the best you can do. I think the worst threat to generalisability is probably the risk of 'experimenter effect', where the students do better in the group that you want to do better. I don't know how to minimise that risk. If Sally Fincher or Mark Guzdial is listening, or anyone else with a good knowledge of these issues, I hope they'll join in.
