This 20-minute tape cassette on students as teachers is one of a series designed to inspire inservice school personnel and provide them with basic information about school innovation. Allen's comments focus on the appropriate teaching roles for students and the advantages of students as teachers. Allen feels that all kinds of students can and should teach--one of the reasons being that teaching is a good learning technique. He has flexible ideas about the size of the group taught, who should be taught, the amount of supervision, and the extension of student responsibility into developing instructional materials and designing courses. To those who think students taught by other students would suffer from occasional inaccurate information, Allen answers that the notion that everything taught in school is right is nonsense anyway and should be discarded if we are really trying to develop critical thinking in students. He cites other advantages of students as teachers, along with several disadvantages (such as exploitation) which, however, he feels can be overcome. (LP)
