Stefanie Brimacomb: EDTECH Learning Log

After reading about the relationships between organization and learning, a looked over print and web learning material for both good and poor examples of Lohr’s principle of organization. The thought process behind developing a learning site surprised me. I realized that in fact, most of the process goes on in the head and on the design pad. This chart represents the Fick Principle or the metabolism of oxygen, and provides a clear understanding of the interaction between what we term as the ABCs – Airway, Breathing, and Circulation. We need oxygen to live at the most basic cellular level. Oxygen is our primary fuel, and our bloodstream is the transport for that fuel to become metabolized. I chose the shapes because they represent molecules of oxygen or carbon dioxide. The red arrows symbolize the blood stream that transports the oxygen. I used a circular model to emphasize the circulatory nature of the cycle with the inhalation situated at the top and moving in a clockwise pattern as common to western culture and the thick arrows suggest a strong relationship between each action (p 128) – if any part of this chain is broken, the cycle becomes incomplete and the human body systems begin an attempt to compensate for the loss. This compensation is known as “shock.” I placed the beginning of the cycle at the top-most position, knowing that my learners are used to a left-right reading order (p. 135). But I will change it to add a slightly larger circle to more clearly define where to begin the cycle.
