The SWRL Instructional Concepts Program has been developed to help kindergarten children quickly learn conceptual skills which are fundamental to academic achievement. Formative evaluation procedures employed in the 1968-69 tryout were primarily responsible for the changes incorporated into the present program. These procedures included teacher interviews, observations of lessons being taught, student tests for each unit of the program, and collection and analysis of pretest and posttest performance data. It is expected that the revised Instructional Concepts Program will be more effective for students and more acceptable to teachers because of the revisions resulting from the formative evaluation procedures.
