Piaget's work is seen as a basis for the assessment of a projected course. The stages of a course ought to follow the same order of increasing logical complexity as are present in the pupils' own development. (LS)

Reports results of a questionnaire given to students taking the College Board Achievement Test in Biology to determine which topics they remembered studying in their first-year biology courses. Concludes that remembered topics were highly correlated with textbook emphasis. (EB)
