ABSTRACT
William Arthur Ward stated, "The mediocre teacher tells. The good teacher explains. The superior teacher demonstrates. The great teacher inspires." Discovery experimentation is an inductive method that demonstrates and inspires by creating an interest in determining the underlining basis of a phenomenon. This experiential approach also fosters motivation and enhances learning. Starting with what the student knows augments this approach. By starting with what the student already knows, the student can consciously and explicitly link the subsequent new information with previous knowledge. Accordingly, we used a simple battery as an analogy for electrocardiogram vectors to introduce the theoretical physics of how the heart produces voltages that are detectable at the body surface. This extraordinarily complex physics was approached in a straightforward and inexpensive way while still providing an understanding of the fundamental concepts developed by Willem Einthoven in 1895.
