Blair Lehman is a learning scientist in the Language Learning, Teaching, and Assessment group at ETS. She received a Ph.D. in cognitive psychology and cognitive science certificate with a focus on artificial intelligence in education from the University of Memphis in 2014. During her doctoral studies, she conducted research on student emotions during interactions with intelligent tutoring systems. She explored how to leverage experiences of confusion during learning to promote deeper learning and how best to support students through this experience. She has applied her knowledge of student emotions during learning to a variety of assessment contexts while at ETS. Her research at ETS has focused on the areas of student emotions and motivation during assessments (traditional and technology enhanced) and learning activities (e.g., mobile-assisted language learning apps). Her work further explores how the intersection of task design, student, and domain characteristics can be leveraged to create educational activities that provide all students with the best opportunity to show what they know or to gain new knowledge.
