A Genetics Role-playing Activity
by: Sharon Nelson
This activity allows students to utilize "the 3 P's" of science: Problem posing, problem solving, and peer persuasion. It does require a great deal of time, but I feel it is one of the best activities I have my students do. The results are lasting, and students feel a definite sense of accomplishment at the conclusion of the activity.
- use research/study skills to investigate a particular human genetic disorder;
- assume role(s) of doctor, genetic counselor, parents, sibling(s), affected individual (as the case requires);
- work cooperatively with other students;
- make informed decision(s) based on consideration of the bioethical issues involved;
- generate a written report summarizing the information gathered;
- give an oral presentation to the class, explaining their particular circumstance, the bioethical issues involved, and the decisions that were made by their group. They will defend their decisions and will answer questions posed to them by their peers (peer persuasion).
Students will be assigned to work in groups of 2-5, at the instructor's discretion. Students will then choose a scenario for role playing. Their job is to research any and all information pertinent to their situation. Students may divide the roles in any way they see fit (one may choose to assume the role of parent, another the role of doctor, etc.) Once they have the necessary information, they must make some decisions regarding their situation, based on the bioethical issues involved. In addition to a 5-10 minute oral presentation, students must, with their group members, turn in one written report.
NOTE TO TEACHERS
Prior to this activity, my students have learned basic Mendelian genetics and a little human genetics. The anomalies in the scenarios have very possibly never been discussed in class. A genetic counselor has also been in to speak with the students (if one is not available, I share the information with the students.) An evaluation sheet is included. I present it to my students at the beginning of the activity so they know exactly how their projects are critiqued.
