When teaching a new skill, clearly it is best to offer a variety of methods in order for your student to successfully learn information being taught. There are many ways to ingest information. For instance: auditory explanations, visual diagrams, showing examples through drama perhaps...and really, the list can go on and on. Thankfully, there are many ways in which we can learn. Some professors will even tell you that the best learning is done through travel. Or from making a personal connection.
