Eye tracking methodology offers insights into human attention, decision-making processes, and user behaviours. In the context of teacher learning, data generated from eye-tracking technology has the potential to provide important information about teachers' behavioural patterns and cognitive processes that may or may not be occurring during learning experiences. This review analyses existing studies that use eye tracking methodology for studying teacher learning. The authors accessed three different databases (ERIC, PsycNet, and EBSCOHost) for their review. An iterative process of reviewing and coding the articles led to an in-depth review of 10 recently published articles. Emergent themes resulted from the in-depth review and include "information processing," "multimedia learning," "learning tools and resources," and "expert-novice knowledge construction." The reviewed articles also highlight how eye tracking can be used to determine teachers' engagement with learning material, reading patterns, and sense-making strategies. Additional study characteristics, including context, data sources, eye tracking device and metrics were also reviewed. Results of this review shed light on how educational researchers can effectively use eye tracking methodology to investigate teacher learning at different career stages. This, in turn, can inform educational stakeholders about how to optimize learning opportunities and environments.
