In assessing student research, clearly defined "right" or "wrong" answers rarely exist. Instead, the goal of assessment is to evaluate the process used by students and the conceptual understandings they have achieved through research experiences. This chapter outlines possible assessment criteria for student research, as well as example assessment rubrics for research posters and reports. It also provides a series of tools for assessing performance as students design and conduct research, interpret and present results, and engage in peer review.
