In this paper we present our experience using code reviews in a CS2 course. In particular, we highlight a series of misunderstandings of object-oriented (OO) concepts we observed as a by-product of the code review exercise. In our activity, we asked students to review code, rate it using a rubric, and to justify their explanation. The students were asked to review two solutions to a project from a previous year. Through examples of their explanations, we found that students had a number of basic misunderstandings of object-oriented principles. In this paper, we present our observations of the misunderstandings, and present some general observations of how code reviews can be used as an assessment tool in CS2.
