The Development, Validation, and Use of an Arbitrary Implementation Scale (AIS) as a Basis for Ex Post Facto Curriculum Evaluation.

Current curriculum evaluation models tend to cater to desirable or ideal situations and offer little help to the evaluator of ongoing curricular innovations, many of which are characterized by little assistance or control of implementation, little monitoring or supervision of operation, and haphazard postimplementation modification or development. This paper describes the conception, operationalization, validation, and role of an Arbitrary Implementation Scale (AIS) in an ex post facto curriculum evaluation model which facilitated the provincewide assessment of an inquiry oriented junior high school science curriculum in Saskatchewan operating within the context described above. The AIS is included in the appendix of this report. (Author/RC)
