A Holistic Approach to Teaching a Laboratory, Using Sea Urchin Development as an Example System

 

Tested Studies in Laboratory Teaching, 1995, Volume 16

Abstract

This exercise uses brainstorming, writing, and oral presentation techniques within the framework of a laboratory to illustrate the basic principles of early development. In groups, students learn how to identify a good model system (the sea urchin), isolate its gametes, mix some gametes from each sex, and study the ensuing processes of fertilization and development. After being introduced to the basic techniques, student groups design their own experimental approaches to further analyze these processes.
