Responsive evaluation: A personal reaction

In examining the Responsive Model, a design for program evaluation, I have approached it, not from the point of view of the evaluation theorist, which I am not, but from the point of view of a faculty member in a health sciences institution who has some responsibility for the evaluation of school programs.My comments and reactions are based not only on Dr. Stake's presentation here, but upon other published and unpublished materials of his. My summary of responsive and pre-ordinate evaluation designs which follow are drawn freely from his work.
