Recent studies (Golan and Reiser 2002) on students’ understanding of fundamental molecular genetics concepts suggest that current instruction in genetics leaves students with an insufficient understanding of the technological advances in molecular genetics that they may encounter in their everyday lives, such as genetic counseling and screening (Lewis and Wood-Robinson 2000). Nor are students informed enough to understand and participate in current debates involving genetic issues such as geneti- cally modified foods, cloning and gene therapy (Garton,1992).
