My teaching strategy was to teach the complicated version of the action potential and then simplify it so that it was easy to remember the steps. I made it very visual. The action potential is a graph representing time in milliseconds and the voltage of the membrane potential in millivolts. As different positively charged ions move in and out across the cell membrane, the voltage changes.
It's always been difficult for students (and myself!) to remember which ion moves when. So I used a video I found on youtube that simplified the memorization.

Then I added the visual aspect by making hats for each ion for the students to wear. I arranged the tables in a circle with spaces in between to simulate the cell membrane and voltage-gated channels. The students (Ions) moved according to Phases 0-4 simulating the movement of the ions and then the sodium-potassium pump at the end.
I also showed the Google slides attached with each phase so that the correlation of Potassium-bananas, Calcium-bones, and Sodium-salt would make it easy to remember. At least laughable and memorable!
The other nice piece to this was that I taught it in CVT 101 Anatomy & Physiology, which is Linda Blais's class. I have been attending her class this semester to learn teaching strategies, review and refresh the material, and really get an idea of what the students are learning so that I can pick up where she left off when they come to EP. It's been a great experience all around!
