The controversy over the University of California, Berkeley's genetic testing project is due to the difference between science and science education, writes Marie-Claire Shanahan, a science education professor, in at guest post at Blog Around the Clock. "They have, in particular, different objectives and different artefacts, rules and actions that guide and shape them," she says. It is there, Shanahan adds, that the Berkeley project gets "fuzzy." How Berkeley describes the project makes it sound educational, yet the tools and some of the language are those of science. "The overall effect is one of a mixed metaphor," she says, and that matters "because the ethical considerations are different."
