Early Warning Signals Appear Long Before Dropping Out: An Idiographic Approach Grounded in Complex Dynamic Systems Theory

Mohammed Saqr, Sonsoles López-Pernas, Santtu Tikka, Markus Wolfgang Hermann Spitzer

TL;DR

This paper investigates whether early warning signals of resilience loss, grounded in critical slowing down (CSD), can forecast student disengagement before dropout in a large digital mathematics platform. It applies idiographic time-series analysis to compute CSD indicators—$AR(1)$, $SD$, $CV$, skewness, kurtosis, and $RR$ with $RR = 1 - AR(1)$—on $1.67$ million practice attempts from $9{,}401$ students. The authors find that $88.2\%$ of students exhibit CSD signals prior to dropout, with warnings clustering late in the engagement sequence and intensifying near disengagement, supporting the existence of universal resilience dynamics in education. These findings point to portable, early-detection tools that could enable proactive, personalized interventions across diverse learning contexts and data types, including multimodal sensor data.

Abstract

The ability to sustain engagement and recover from setbacks (i.e., resilience) -- is fundamental for learning. When resilience weakens, students are at risk of disengagement and may drop out and miss on opportunities. Therefore, predicting disengagement long before it happens during the window of hope is important. In this article, we test whether early warning signals of resilience loss, grounded in the concept of critical slowing down (CSD) can forecast disengagement before dropping out. CSD has been widely observed across ecological, climate, and neural systems, where it precedes tipping points into catastrophic failure (dropping out in our case). Using 1.67 million practice attempts from 9,401 students who used a digital math learning environment, we computed CSD indicators: autocorrelation, return rate, variance, skewness, kurtosis, and coefficient of variation. We found that 88.2% of students exhibited CSD signals prior to disengagement, with warnings clustering late in activity and before practice ceased (dropping out). Our results provide the first evidence of CSD in education, suggesting that universal resilience dynamics also govern social systems such as human learning. These findings offer a practical indicator for early detection of vulnerability and supporting learners across different applications and contexts long before critical events happen. Most importantly, CSD indicators arise universally, independent of the mechanisms that generate the data, offering new opportunities for portability across contexts, data types, and learning environments.

Figures (3)

  • Figure 1: The figure highlights phases of resilience: initial state, the disruption, recovery, adaptation, and the establishment of a new engagement level. Resilience—through absorptive, recovery, and adaptive capacities—shapes how quickly and effectively engagement recovers. A resilient student (green) recovers faster and reaches a higher engagement level, while a less resilient student (blue) faces a longer decline, slower recovery and a lower final level rehak2018resilience
  • Figure 2: Panels (a) and (b) illustrate the system’s stability landscape. In panel (a), the system resides in a stable state (state A), characterized by high resilience to perturbations and a fast recovery rate; disturbances do not push the system toward the alternative state (state B) because of the deep basin of attraction. In panel (b), the system approaches a critical transition: the basin of attraction becomes shallower and narrower, increasing the likelihood that perturbations will shift the system to an alternative stable state (state B). Panels (c) and (d) show the corresponding time-series behavior. In panel (c), a stable system exhibits low variance and low autocorrelation, indicating small, rapidly damped fluctuations. In panel (d), as the system nears a tipping point, both variance and autocorrelation increase, reflecting larger and more persistent fluctuations. This pattern signals critical slowing down (CSD) and serves as an early warning of an impending transition scheffer2009early.
  • Figure 3: A time series with detected warnings (top panel), the scaled metric values of various early warning indicators over time (middle panel), and the corresponding system state inferred from these signals (bottom panel). The top panel presents a raw time series, with red dashed lines indicating periods where EWS were detected. The middle panel plots the scaled values of several EWS indicators (ar1, cv, kurt, rr, sd, skew) over time. Darker dots on these indicator lines signify detected EWS. The bottom panel visually represents the system State transitioning from Stable to Vulnerable, Warning, Critical, and Failing, based on the combined EWS signals.
