The methodology of eye tracking has been gradually making its way into various fields of science, assisted by the diminishing cost of the associated technology. In an international collaboration to open up the prospect of eye movement research for programming educators, we present a case study on program comprehension and preliminary analyses together with some useful tools.

The main contributions of this paper are (1) an introduction to eye tracking to study programmers; (2) an approach that can help elucidate how novices learn to read and understand programs and to identify improvements to teaching and tools; (3) a consideration of data analysis methods and challenges, along with tools to address them; and (4) some larger computing education questions that can be addressed (or revisited) in the context of eye tracking.
