The present study investigates university students’ time estimation accuracy from a Self-Regulated Learning perspective. Specifically, the study examines students’ goal quality, competence for goal completion, and perceptions of goal difficulty as predictors of time estimation accuracy for single study session at three points over a semester. An additional goal of this study was to investigate the relationship between time estimation accuracy and students’ reported goal completion. Results show that more than 50% of students underestimated or overestimated their time to complete goals at every time point over the semester. Results of multinomial logistic regression analyses demonstrated that perceived goal difficulty was a predictor of underestimation at the middle and at the end of the semester, competence for goal completion predicted time estimation accuracy at the beginning of the semester, and goal quality was not a significant predictor of time estimation accuracy at any point in the semester. Lastly, students who overestimated the time spent in their study sessions were less likely to attain their goals. These results provide empirical evidence of the prevalence of misestimation during individual study sessions guided by goals created by students for course-relevant tasks and partial support to theoretical principles of SRL, which consider task perceptions and goal setting as determinants of the learning process. / Graduate / 2023-06-27
