Erin Walker joined our department in January 2019 as an Assistant Professor. Her research uses interdisciplinary methods to improve the design and implementation of educational technology and to understand when and why it is effective. She is particularly pursuing projects that incorporate social and contextual adaptation into learning environments, including implementing a teachable robot for mathematics learning, using technology to support peers in giving help across different platforms, and developing an intelligent tutoring system to help parents and children read together. The second line of her work relates to the careful design of technology to facilitate the development of a finer-grained understanding of learning processes. For example, one project looks at how brain data and log data can be combined to infer a learner’s cognitive and motivational state. Overall, her work spans questions related to intelligent tutoring systems, computer-supported collaborative learning, human-robot interaction, and brain-computer interaction.
