Title: Eliciting Proactive and Reactive Control during Use of an Interactive Learning Environment

Abstract: The dual mechanisms of control framework describes our ability to shift between proactive control (goal maintenance) and reactive control (goal activation on task demands), and may explain variations in user performance in computing tasks. Although these mechanisms are relevant to the design of interactive systems, and particularly educational systems, their relation to HCI is under-researched. In this talk, I describe a learning manipulation we designed to induce proactive or reactive control in the context of mathematical problem solving on an online tutoring system. I talk about two experiments where students solved problems using either proactive or reactive control. Study 1 validates the manipulation by investigating behavioral measures that reflect usage of the intended strategy and assesses whether either cognitive control mode impacted learning. Study 2 investigates whether alternating between control modes during problem solving affects student performance.
