Science teachers' social conscience and the role of controversial issues in the teaching of science

The increasing number and variety of controversial scientific and technological issues with which citizens are confronted has led, in recent years, to calls for a schooling of science which prepares future citizens for participation in resolving such issues. We examined the social conscience of science teachers as it bears on the teaching of controversial issues. The study was conducted by interviewing teachers in two widely different English-speaking locations, Scotland and the United States. The research explores the perceptions of teachers with regard to the teaching of controversial issues, the problem of handling personal value positions when dealing with issues, and the tension that exists between the teaching of controversial issues and traditional value-free science curricula.
