Instead of merely attending to different categories and trying to find some sort of similarity or difference, synthesizing is a matter of pulling various sources together into some kind of harmony. It is the ability to combine clearly and coherently the ideas of more than one source with your own.
Synthesizing information is the way that students can take information from multiple sources and bring the information together. When these sources are combined together, it creates one cohesive idea. This is typically how students learn new ideas, theories and information in class.
