Third, there is a real problem when we come to examine what educators actually do in the classroom, for example. Much of the
research concerning teacher thinking and classroom interaction, and curriculum innovation has pointed to the lack of impact on actual pedagogic practice of objectives (see Stenhouse 1974; and Cornbleth 1990, for example). One way of viewing this is that teachers simply get it wrong - they ought to work with objectives. I think we need to take this problem very seriously and not dismiss it in this way. The difficulties that educators experience with objectives in the classroom may point to something inherently wrong with the approach - that it is not grounded in the study of educational exchanges. It is a model of curriculum theory and practice largely imported from technological and industrial settings.
