Improving student learning through understanding reasoning and problem solving tactics

Classroom practices affect student behavior, and by extension, their learning. Through studying how students discuss clicker questions in active learning classrooms, we have found that students rarely use reasoning when answering in-class questions. However, their use of reasoning increases when they are cued to use reasoning by instructors or peers, or when under pressure of accountability. Can students transfer in-class group practices to individual assessment opportunities that require reasoning and logic?

Neural and Behavioral Dynamics of a Social Interaction

Social interactions require continually adjusting behavior in response to sensory feedback. For example, when having a conversation, sensory cues from our partner (e.g., sounds or facial expressions) affect our speech patterns in real time. Our speech signals, in turn, are the sensory cues that modify our partner’s actions. What are the underlying computations and neural mechanisms that govern these interactions? To address these questions, my lab focuses on the acoustic communication system of Drosophila.
