Title: Leveraging technology to conduct field experiments and dynamically enhance and personalize user interfaces

Video Recording of Talk
ABSTRACT:Understanding people's complex real-world thinking is a challenge for psychology, while human-computer interaction aims to build computational systems that can behave intelligently in the real-world. This talk presents a framework for redesigning the everyday websites people interact with to function as: (1) Micro-laboratories for psychological experimentation anddata collection, (2) Intelligent adaptive agents that implement machine learning algorithms to dynamically discover how to optimize and personalize people's learning and reasoning. I present an example of how this framework is used to embed randomized experiments into-real world online educational contexts - like learning to solve math problems- and machine learning used for automated experimentation. Explanations (and experimental conditions) are crowd sourced from teachers and scientists, and reinforcement learningalgorithms for multi-armed bandits used in real-time to discover the best explanations for optimizing learning.
