Students today routinely conduct research in the digital world to solve problems in daily life and in learning tasks. Although research to date has proposed different models to describe the processes of information problem solving (IPS), little is known about the cognitive patterns demonstrated in the processes, particularly the iterative nature of IPS and the driving factors behind iterations. The current study employed the lens of a self-regulated problemsolving model to develop an in-depth understanding of learners’ IPS processes. Analysis and cross comparisons of three students’ on-screen research activities, think-aloud articulations, artifacts, and interviews revealed three representative patterns for performing an IPS task: reasoning-driven, prior knowledge/taskdriven, and information-driven. | Exploring patterns in undergraduate students’ information problem solving: A cross-case comparison study
