This tape cassette on inservice teacher education is one of a series designed to inspire inservice school personnel and provide them with basic information about school innovation. Allen begins his 20-minute recording with the assertion that certification is not the end of teacher education even for well-trained teachers, simply because the field does not remain constant. In citing the disadvantages of inservice institutes and after-school meetings, Allen calls for inservice education that is an integral part of the teaching day and that may take up 20 percent of a teacher's time. Although he envisions the cooperation of universities and schools, he believes that the primary site for inservice education should be the school, in which inservice courses should be oriented toward the objectives of the particular school and should provide opportunities for teachers to specialize and explore alternative curriculums. The cost of inservice education may become 10 percent of the district's personnel costs, according to Allen. (LP)
