indicated that boys receive more attention, praise, blame and punishment in the grammar-school classroom, and "this pattern of more active teacher attention directed at male students continues at the postsecondary level". Over time, female students speak less in a classroom setting. Teachers also tend to spend more time supporting the academic achievements of girls. Boys are frequently diagnosed with ADHD, which some see as a result of school systems being more likely to apply these labels to males. A recent study by the OECD in over 60 countries found that teachers give boys lower grades for the same work. The researchers attribute this to stereotypical ideas about boys and recommend teachers to be aware of this gender bias.
