This guide is written for Saskatchewan science teachers (particularly grades 7-12) who wish to know more about features of the proposed new science curricula for Saskatchewan. The purpose is to clarify the expanding repertoire of science teaching strategies which a teacher will develop as he or she implements one of the new science courses in Saskatchewan. Suggestions on how to use the "new" strategies are also included. The guide describes and discusses instructional strategies often employed in teaching science through a science-technology-society-environment (STSE) emphasis. Discussions on the following strategies are included: (1) "Divergent Thinking"; (2) "Small Group Work"; (3) "Student-Centered Class Discussion"; (4) "Problem Solving"; (5) "Simulations"; (6) "Decision Making"; (7) "Controversies and Dilemmas"; (8) "Debating"; (9) "Resource Books"; (10) "Mass Media"; and (11) the "Community". Appendices include an evaluation sheet and a checklist for group assignments, a detailed analysis of debates and their evaluation, and an excerpt from "Science Technology Society" discussing "New Instructional Strategies".
