Three colossal neurons: a new approach to an old classroom demonstration

Research suggests that the key to optimal student learning, regardless of class size, is engaging students in active learning. It is my contention that to truly understand neural processing, one must not only understand the activities of the neuron as a living cell, but also how that cell works within the context of a neural network. The demonstration exercise described herein combines techniques expressed in three previously published articles, with certain modifications, allowing as few as 15 and as many as about 200 students to actively participate in the endeavor. Moreover, test scores from 158 students were examined, showing that students who participated in the demonstration performed significantly better on exam questions than students who did not take part.
