Coasting Through Class: Learning Opportunity Loss from Practice Avoidance During Individual Seatwork

2026-04-27

AI Summary

This study addresses the pervasive issue of task avoidance in classroom practice, which results in substantial lost learning opportunities. While prior research has predominantly focused on within-task idling, it has largely overlooked session-level delays in initiation and premature termination. To bridge this gap, the authors introduce the novel construct of “slacking time,” integrating both within-task disengagement and session-level off-task behaviors. Leveraging log data from the ASSISTments platform, they quantify slacking time through behavioral sequence analysis and assess its stability using G-coefficient reliability testing. Findings reveal that students spend only 40% of classroom time on effective practice, with the remaining 60% classified as slacking time. This behavior demonstrates moderate temporal stability, and crucially, students who persist in practicing beyond their initial task completion show significantly higher performance on standardized assessments, underscoring the detrimental impact of slacking time on learning outcomes.

Abstract

Measures of disengagement provide insights into unproductive use of learning opportunities. Although measures of active disengagement, such as gaming the system and mind-wandering, are well studied, loss of practice time due to outright task avoidance remains relatively understudied. The current study addresses this gap by extending existing within-task measures (idle time) with two new session-level measures (delayed start and early stop) to capture loss of practice time due to task avoidance. We characterize the combined lost time as coasted time and the associated behavior as coasting behavior. Using ASSISTments logs (N = 1,425), we find that students dedicate only 40% of available classwork time to math practice and coast through the remaining 60%. Of the coasted time, 36% resulted from delayed starts, 2% from mid-practice idling, and 62% from stopping early. Delayed start and early stop showed moderate temporal stability (G = 0.73 and 0.71, respectively), suggesting that coasting is a consistent behavioral pattern. Even after excluding early stops attributable to assignment completion (i.e., early stop = 0), coasted time remained substantial at 32%. While we observe significant differences in coasting by gender and IEP status, we do not observe them by other demographic factors or school locale. Critically, students who continued working beyond the first assignment completion ("extra effort") performed significantly better on standardized tests. For research, coasting offers a new lens on opportunity loss by combining session-level disengagement with within-task disengagement. For practitioners, our results highlight the need for platform affordances that support sustained engagement and more productive use of available practice time.
