Biotechnology in Agriculture, Food, and Human Health is a World Wide Web course developed by Project BIO, a program to develop and share Internet biology education resources, at Iowa State University. This course has been utilizing problem-based learning as a mode of instruction in a unit dealing with pre-symptomatic DNA testing for a genetic disease. Problem-based learning is the use of a "real world" problem or situation as a context for learning. Quantitative and qualitative assessments of student gains in critical thinking, improvements in ability to solve real-world problems, acquisition of knowledge, development of the ability to work productively as a team member, and development of skills supporting life-long learning were analyzed. The current study indicates that problem-based learning is a valid and efficient means of expanding student learning in on-line courses.
