Biological Sciences covers an enormous range of disciplines, many of which incorporate sensitive and contentious areas which have major ethical implications. The QAA Biosciences benchmark statement (QAA, 2002) also requires students to be provided with a training in ethics. Whilst the Faculty of Biological Sciences, University of Leeds provides some ethics training for its students, it is not available to all students, nor is it provided in an integrated way. The award of a Centre for Excellence in Teaching and Learning in Interdisciplinary Ethics (IDEA CETL) to the University has provided a unique opportunity for biological scientists and ethicists grounded in philosophy to work in partnership to address this problem. Our aim is not to replicate case studies or teaching material in areas where these already exist, but rather, to produce subject-specific materials in areas where these are not available in order to fulfill our objectives. Our strategy has been to provide a comprehensive and progressive training in ethics throughout individual degree programmes. Within our undergraduate programmes, we have introduced students to ethics and ethical thinking at Level 1, with topics covering both non-discipline specific issues (e.g. plagiarism) and discipline-specific issues which require limited subject-specific knowledge (e.g. drugs in the third world). This training continues at Level 2 where we introduce discipline-specific issues such as the use of animals in scientific research; these seminars covering both the law and the wider ethical implications of such studies. At level 3, we have developed an optional ethics module providing advanced training in ethics and ethical thinking for Biomedical Sciences students. Given that a significant number of biological sciences graduates do not subsequently undertake a career in research, we are developing ethics-based “teaching” or “public understanding of science” projects as an alternative to laboratory-based final year projects. This development of ethics provision extends to all of our postgraduate courses, with both taught and research students being provided with training in generic and discipline-specific issues throughout their programmes. Overall, we seek to equip our graduates with the ability to think through ethical issues which they may encounter in future employment, regardless of career chosen. Having developed these teaching materials, we also seek to disseminate them to other interested subject practicioners. Thus, all the materials required for delivery of the individual topic by a non-ethicist are available via the IDEA CETL website.
