The design of this experiment is terrible. At best it proves that the VARK questionnaire does not correlate with actual learning style but I don't even think it even does that due to the poor experimental design. Perhaps it is leaning heavily on previous findings but since the population selection is so heavily biased to begin with and the course appears to be conventionally taught rather than making equally comprehensive study aides for the different styles. The fact that more than half of the students did not study using the style they self reported to prefer with is also an obvious red flag. Note I believe VARK is over simplified nonsense but so is this research.
