Chess instead of math: the clearest signal was in pattern recognition
The clearest signal appeared in pattern recognition. There was no firm evidence of improvement on other tests.
The study, in plain language
In five public schools in Denmark, some classes replaced one weekly math lesson with chess. Principals decided which ones, without random assignment. Children took tests before and after, and results were compared using different adjustments.
The favorable result was more visible in pattern recognition. There was no similar signal in problem solving, and several overall differences weakened after adding controls for schools. The findings therefore do not show a broad, firm advantage for chess.
The key idea
The favorable signal for chess was small and appeared mainly in patterns. Classes were not randomly assigned, and several results weakened after adjustment.
Something to think about
If a school tests a new activity in classes it chooses, how much of the result comes from the activity and how much from those classes? Several differences shrank after accounting for schools.
