Abstract

To address the limitations of existing academic performance prediction studies, such as insufficient prediction timeliness and continuity and the neglect of changes in learning states, this paper proposed a lightweight spatio-temporal model for learning behavior indicator prediction, termed LST-LBIP, in line with recent developments in time series forecasting, and enabled prediction at a weekly temporal granularity. The model employed a lightweight spatio-temporal attention mechanism to assign weights to feature data and integrated MinGRU to achieve efficient multivariate time-series modeling under limited-sample conditions. In addition, the model designed a correction mechanism that combined heteroscedastic regression and Kalman filtering to enhance prediction stability, and introduced an adaptive sliding-window length component to dynamically optimize the range of historical information used. Experiments on blended learning behavior data collected from three student cohorts over 18 instructional weeks show that the model achieves an average R2 of 0.805, outperforms several commonly used time-series modeling methods, and effectively supports continuous tracking and accurate prediction of students' learning states.
