Models are an integral part of the scientific process used to represent ideas, solve problems, predict outcomes, and test theories.  Modeling involves a broad set of skills and approaches, including quantitative reasoning.  Students are exposed to models throughout their education, but may not understand the role of modeling in the scientific process or how to use models to increase their content knowledge.  The Quantitative Undergraduate Biology Education (QUBES) project has been supporting a working group exploring how this key scientific practice be more effectively used in undergraduate biology education.
