(22) John Linneball's answer to Why would a teacher write questions on the board, then have students rewrite the questions themselves on paper before writing their answers? - Quora

Or if the papers are going to be collected as graded assignments, it makes it easier for the teacher to know what problems the students are attempting to solve.
