I regard using spreadsheets as programming.

Sure, I seen it the same way. Programming is creating general "rules" that will apply to different cases/situations. Is organized and logical thinking.

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.

As a collegue of mine suggested, I will have students take their final test in a double-blind situation. Furthermore, the final test will include the same evalutation tests that students used to take in the past years. So, no test question will be specifically designed to match the explanations/usage of the new tool.

I don't know if this is enough, or if other strategies can be succefully applied.
