Unless students were randomised to attend ALEKS or MOEMS sessions - and the results analysed on the basis of where students were randomised to, regardless of whether they actually attended - this comparison has no value. Were they?
( My intuition is that you're basically right, *but* that there will be significant numbers of students, including some with huge potential, not reached by any optional competition programme. My first step would be to make actually competing in the competitions optional, and advertise that it's perfectly fine to come to sessions to work on problems and never actually compete.)
