A concept map for TUCC and DaVita is shown here. Concept Maps allow students to graphically or visually convey their knowledge or comprehension of a topic. This open-ended activity asks participants to draw or write their thoughts on a topic and to make connections or ties between similar concepts. Concept Maps can be used to assess students' degree of knowledge with a topic at the start of a program, as well as how their comprehension evolves over time.
