Professionals in teaching jobs are being encouraged to let children shout out, with research suggesting that youngsters exhibiting such impulsive behaviour tend to score higher on tests.
According to a study of 12,000 pupils across England by Durham University, children who shouted out in class performed better in maths and English than their quieter counterparts.
This led researchers to the conclusion that "blurting out" actually helps children learn – although it could equally be a sign of children who are more receptive to learning and engaging with teachers.
The study looked at a range of different children, including those diagnosed with Attention Deficit Hyperactive Disorder (ADHD).
Lead author Professor Peter Tymms, head of the School of Education at Durham University, said: "Children with ADHD symptoms who get excited and shout out answers in class seem to be cognitively engaged and, as a result, learn more.
"Perhaps those children also benefit from receiving additional feedback and attention from their teacher."
Co-author Dr Christine Merrell added that while it may seem disruptive, shouting out answers "clearly helps these pupils to learn", and went on to suggest that more attention should be given to how such interaction can be managed in the classroom.
