I've just read a quite interesting piece on myths about brain (i.e. Not supported by science) that are pervasive among teachers including those in UK. It might be just seen as curious facts if it wasn't suggested that they lead to poor teaching.
Here is an excerpt from the summary:
A quarter or more of teachers in the UK and Turkey believe a student's brain would shrink if they drank less than six to eight glasses of water a day, while around half or more of those surveyed believe a student's brain is only 10 per cent active and that children are less attentive after sugary drinks and snacks. Over 70 per cent of teachers in all countries wrongly believe a student is either left-brained or right-brained, peaking at 91 per cent in the UK. And almost all teachers (over 90 per cent in each country) feel that teaching to a student's preferred learning style auditory, kinaesthetic or visual is helpful, despite no convincing evidence to support this approach.
The new research from the University of Bristol, published in Nature Reviews Neuroscience, calls for better communication between neuroscientists and educators.
Dr Paul Howard-Jones, author of the article from Bristol University's Graduate School of Education, said: "These ideas are often sold to teachers as based on neuroscience -- but modern neuroscience cannot be used support them. These ideas have no educational value and are often associated with poor practice in the classroom."
