Refresher courses do not keep teacher abreast with now educational theories anthropologist Margaret Mead said last night in a talk on "the School in American Culture." Miss Mead delivered the Inglis Lecture on Secondary Education is Fogg lecture hall.

Miss Mead also emphasized that if teachers devote all their time to one age group they may distort their view of modern youth and develop unchanging stereotypes of their students.

Miss Mead also said that it was necessary for teachers to change with the times. "To a teacher who does not change," she added, "children of today become totally incomprehensible when compared with the children of 20 years ago."
