conducted a study on American kindergarten shows
found that teachers used information about pupils' home background and appearance to sort them into groups and seated each group at a different table
those who the teacher decided were fast learners were labelled as 'tigers'
these tended to be middle class pupils
they usually had neat and clean appearances
these students were seated at the desks closest to the teacher to show them great encouragement
the other two groups the teacher labelled as 'clowns' and 'cardinals'
these groups were seated further away form the teacher
they were likely to be working class
they were given lower-level books to read and given fewer chances to show their abilities
