Dev Tutorials

Dev Tutorials are video recordings of developmental biologists describing key concepts in the field. These tutorials are primarily authored by Drs. Michael Barresi and Scott Gilbert who are the co-authors of the 11th Ed. of the textbook “Developmental Biology” by Sinauer Associates. These lessons are to complement the chapters within this text book and serve as a basic coverage of these key concepts.

Purpose: Teachers are encouraged to use these Dev Tutorials to supplement the text and provide an opportunity to offer a “Flipped Classroom” approach to teaching Dev Bio. Students watch these Dev Tutorials before coming to class; then, while in class, teachers can incorporate more active learning approaches such as interactive case study problems that are also offered with the 11th Ed.

*These Dev Tutorials are the sole production of Smith College and will always be freely available to all from this website.
