This teacher's guide was developed to assist teachers in supplementing junior high and high school science and social studies programs with a study of the relationships between science, technology, and society (STS). The program is intended to focus on the improvement of student knowledge about STS issues and the teaching of skills related to logical reasoning, critical thinking, problem solving and decision-making. The document contains major sections on: (1) science education for the 1980s and beyond; (2) preparing today's students for tomorrow's world; (3) the science-technology-society program (providing information on the audience, program usage, program objectives, theoretical basis, the development of mental structures, the development of thinking skills, the acquisition of knowledge and information, and the socio-scientific reasoning model); and (4) teaching approaches (including readings, development of critical thinking through reading, classroom discussion activities, questioning strategies, writing activities, dilemma discussions, and debates).
