For more than two decades proponents of the STS movement advocate the
integration of science, technology, environment and societal issues in science
curricula claiming that there is no such thing as ‘‘pure science’’ and that science
education should follow the way scientific investigation is subject to social, environmental
and political considerations. Therefore, a major objective of a STS
curriculum is to give students knowledge about the science/society interface and
the ability to make decisions about science-related social issues. To many STS
advocates, the highest goal of STS education is social action or encouraging
activism. Students should be able to identify science-related social issues, analyze
the context in which the issues are played out in society, know the key individuals
and groups involved
