This two-part observational and intervention study addressed the role of the smartphone in self-regulated learning (SRL) and student success as measured by achievement. Smartphone usage among students has been identified as contributing to lower academic achievement in a variety of settings. What is unclear is how smartphone usage contributes to lower outcomes. This study surveyed participants' self-regulated learning skills and smartphone usage at the beginning and end of the term for first semester undergraduates. A regression analysis demonstrated that when controlling for prior achievement, general SRL measures had a positive impact on first semester achievement. Smartphone related SRL did not have a direct impact on achievement. The second part of the study evaluated the efficacy of a brief intervention to ameliorate factors contributing to lower achievement. Students were presented with either SRL strategies, awareness and attention strategies or career planning guidance (control). A regression analysis of the brief intervention resulted in modest gains in SRL but did not influence achievement.
