I like the information that referred to students using their previous knowledge and life experiences as places to build their knew knowledge upon/learn new knowledge. For example: A student works on cars and has an understanding of pumps and how they work....he was able to apply this to how much air in the chambers of the heart it might take to make it sputter/quit (air embolism)....I thought that was awesome. He was able to use his previous knowledge to make understanding and application to his learning of the functioning of the human body.
