The purpose of this module is to introduce students (grades 10-11) to critical bioethical issues by considering moral dilemmas and knowledge of biomedical advances. The module is organized into 12 topic areas, each containing a dilemma story, introductory reading material, sample student responses, and questions. Dilemmas are essentially brief stories which pose a critical decision to be made by a main character. This decision revolves around conflicts between two or more moral/ethical issues (as identified by Kohlberg) presented in the situation, and it is the moral/ethical implication that provides the thrust for student discussions. Preceding each dilemma are relevant readings or case studies providing basic background information regarding the bioethical issue presented in the dilemma. Questions and sample student responses (representing positions taken by typical students) serve to stimulate thinking about the issues and generating discussions. Issues examined include organ transplantation; kidney dialysis patient selection; drug experimentation; fetal research; human behavior control; mass screening for genetic disorders; the terminally ill; mass screening for psychological disorders; eugenics; infanticide; test tube babies; and recombinant DNA. The module may be used as a separate unit of study, as a mini-course, or incorporated into biology, genetics, civics, history, philosophy, anthropology, health, or family-living courses. (JN)
