The purpose of this qualitative descriptive case study is to benefit our understanding of the potential of online homework as it relates to developing and supporting students' self-regulated learning (SRL). This descriptive case study explores the use of self-regulated learning (SRL) strategies reported by students in the context of completing online mathematics homework (OHW). Eighth-grade students (10 total) from a traditional middle school were interviewed using a validated data collection instrument, the Self-Regulated Learning Interview Schedule or SRLIS (Zimmerman & Martinez-Pons, 1986, 1988). Students' open-ended responses were interpreted using a framework of self-regulation theory and coded using 14 self-regulation strategies to identify the strategies used and to understand differences or similarities among students among different achievement groups (low or high). Students reported using a variety of SRL strategies while completing OHW. All but two students reported "goal-setting and planning and seeking social assistance" (from teachers, adults, and peers). Additionally, this study identified two new categories of seeking non-social assistance -- online resources in general and those from the Khan Academy in particular. Among achievement groups, students in the high-achievement group reported greater use of the cognitive SRL strategy "organizing and transforming," whereas students in the low-achievement group had more recurrent reports of "no strategy." Students in the low-achievement group reported use of the motivational SRL strategies, "environmental structuring" and "self-consequences," whereas students in the high-achievement group reported no use of motivational SRL strategies, but instead reported parent-initiated involvement.
