'Don't teach maths or physics to kids on Thursdays'
"Children have their own bio-rhythms and Thursday is the hardest day of the week," RIA Novosti quoted Gennady Onishchenko as telling the Ekho Moskvy radio station in an interview.
"Therefore, it is not recommended to teach difficult subjects like mathematics and physics on Thursdays because those subjects require a heavier load on the brain," he said.
The doctor said there are special conditions in school scheduling and that parents should know about them. Parents should also take a more active role in curriculum planning to cut down on excessive mental load on children.
