Understanding students’ self-regulated learning (SRL) behaviors in open-ended learning environments (OELEs) is an on-going area of research. Whereas OELEs facilitate use of SRL processes, measuring them reliably is difficult. In this paper, we employ
, a recently-developed approach to analyzing students’ problem solving behaviors in OELEs, to study how student behaviors change over time as they use an OELE called
. Results show interesting patterns in students’ day-to-day transitions, and these results can be used to better understand the individual student’s characteristics and the challenges they face when learning in OELEs.
