Concept mapping is a pedagogical technique that was developed in the 1970s and is being used in K-12 and postsecondary education. Although it has shown excellent results in other fields, it is still rare in political science. In this research note, I discuss the implementation and testing of concept mapping in my Advanced Introduction to International Relations course. I find that student self-reporting indicates that this approach has a positive impact on student comprehension of texts and learning in the course. I suggest improvements that I intend to implement with the technique, as well as a future research agenda.
