Procedures for revising a K-12 social studies program so that it includes thinking skill activities and for implementing the revised curriculum are discussed. Procedures are: the formation of a curriculum committee and sub-committees; current program assessment to determine needs regarding thinking skills; deciding on a rationale; selecting objectives; incorporating thinking skills into the objectives (with a focus on the cognitive domain as outlined in the six categories of Bloom's Taxonomy of Educational Objectives); determining the scope of the program; choosing the content; identifying and selecting instructional materials; and planning for program evaluation. To ensure that the revised curriculum is implemented in a manner that maximizes success, in-service teacher education workshops that focus on how to teach thinking skills must be conducted. The implementation process also involves determining whether computer assisted instruction is to used and to what degree. Finally, a timetable for reviewing and assessing the revised curriculum is essential. (RM)
