All I Really Needed to Know I Learned during Gastrulation

Abstract

Note from the Editor Points of View (POV) address issues faced by many people within the life science education community. CBE—Life Sciences Education (CBE-LSE) publishes the POV Feature to present two or more opinions published side-by-side on a common topic. We consider POVs to be “Op-Ed” pieces designed to stimulate thought and dialogue on significant educational issues. They are not meant to be exhaustive treatments of a subject. In this issue, we ask the question, “What are key concepts in developmental biology?” We present three POVs. The first is by CBE-LSE Editor-in-Chief, William Wood, and it is in part based on his experience teaching developmental biology to undergraduates at the University of Colorado, Boulder, including his collaborative experiments in the classroom with Jennifer Knight, the first results of which have been published in CBE-LSE ( Knight and Wood, 2005 ). The second, a partially tongue-in-cheek list of key concepts to convey to students about embryonic development, is by Scott Gilbert (Swarthmore College), author of the leading textbook worldwide for teaching developmental biology, Developmental Biology, 8th ed. (Sinauer Associates, Inc.). The third is by Jeff Hardin (University of Wisconsin–Madison), who has produced Web-based educational materials for teaching developmental biology that are used nationally and internationally for conveying dynamic events during early development (see the WWW feature in this issue by Stark for more details), and who deals with the vexing problem of trying to convey the essential four-dimensional nature of embryonic development to introductory students. This list of key principles in animal development was presented as “life lessons” at the Society for Developmental Biology national meeting in 2005, and it has been edited somewhat for inclusion here.
