A model for how students develop principle-based reasoning in physiology
To gain expertise in a field is to understand and use underlying disciplinary principles. Too often students rely on rote memorization to solve problems rather than apply appropriate principles of physics that governs biological phenomena, that is, use principle-based reasoning. Students who rely on memorization can list the steps of generating an action potential or stomatal opening but cannot reason to a correct prediction when changes are introduced in the system, e.g. when a toxin is applied.
