Abstract of My Journey

I was filled with excitement as I left DC and eager to redo my Anatomy and Physiology I course (first semester of a two semester treatment) around the use of case studies.  I started creating the new course design right away to pilot the experiment proposed at the BSP workshop.  I searched the National Center for Case Studies Teaching in Science--Suny Buffalo for appropriate cases to teach of several concepts always taught in the first unit of API.   I utilized a specific design from a book entitled "Pathways to Scientific Teaching," ed. Diane Ebert-May and Janed Hodder.  They specifically do active learning in large lecture classroom settings and have a very effective method of organizing especially the first several days of class.  I used 6 of 7 planned cases to illustrate homeostasis, negative feedback mechanisms, cell membranes and organelles, and osmosis.  The class was modeled after the "flipped" classroom whereby students read materials outside of the "lecture" period and then use the class period to ask questions and solve problems in solving the cases.  I gave "mini" lectures when I saw the need arise after circulating around the groups to see the major misconceptions and difficulties that the students were having.  Long story short, the unit was a success!  Written feedback was encouraging.  Not only, I performed a pre-post test for the unit and got a significant increasing in content/concept learning.  HOWEVER, since I do not have graduate students, the grading took so much time away from my other classes that I had to abandon the rigorous format for the second through fourth units!  I still did case studies but not to demonstrate EVERY concepts.  I was only able to manage two cases per unit, and slipped back into the modified lecture model.

I have found a college science teacher in my department to help me design the next iteration of the experiment.  Hopefully, the experimental design will be much better with the help of a newly minted curriculum design Ed.D. in science education.  The data collected will be more robust than the data from the pilot study.
