WORKSHOP
Teaching Workshop: Changing the animal science teaching and learning paradigm—An interactive work-
shop on how to use case study teaching to foster critical thinking and classroom discussion
 
Sponsors: USDA-National Institute of Food and Agriculture and Virtus Nutrition 
Suwannee 13/14 
7:30 AM to 5:00 PM
The purpose of the case study workshop is to engage participants in different types of case study methods of instruction, 
demonstrate how to teach with case studies, and how to write cases and teaching notes so that others individuals can use 
them. During this highly interactive workshop, participants will experience case study teaching from the student’s viewpoint, 
and discuss how this teaching method can contribute to critical thinking and effective classroom discussions. In breakout ses-
sions, participants will write their own cases or modify existing cases relevant to specific disciplines within the animal sciences 
undergraduate program (e.g., nutrition, genetics, management, physiology). This daylong workshop will be facilitated by Dr. 
Clyde (Kipp) Herreid, who is the founding director of the National Center for Case Study Teaching in Science (http://science-
cases.lib.buffalo.edu/cs/) and distinguished teaching professor of the State University of New York. Kipp has published over 
150 articles and five books in the fields of ecology, behavior, and physiology of animals and written extensively in the field of 
science education.
