A diagram that shows the relationships among ideas to help users understand how ideas are connected. Concept maps are generally composed of two elements: concepts (usually represented by circles, ovals, or boxes and are called nodes); and relationships (usually represented by arrows that connect the concepts; the arrows often include a connecting word or verb and these arrows are called cross-links.  There are four types of common concept maps: (1) spider maps, (2) flowcharts, (2) hierarchy maps, and (3) system maps.
