The question of how students manage and allocate their study time is a complex problem, consisting of decisions regarding switching between material, stopping studying, deciding what to prioritize, how long to study given material, and what learning goals to set. The first project detailed investigates switching decisions, investigating how students choose to switch between lists. Several experiments investigate the effects of self-efficacy on metacognitive judgments and study behaviors such as study time, study strategies, and goal setting and achievement. The third project investigates metacognitive framing, a factor that may influence metacognitive judgments, and potentially, study behaviors. The last project examines the influence of different kinds of study scenarios on metacognitive judgments, specifically, repeated testing, spaced restudy, and massed study. Together, these lines of work show evidence of how metacognitive judgments are influenced, how students choose to switch between materials, and how students enact study strategies to achieve learning goals.
