Subclaims¶

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? Total time in the DLP was positively associated with standardized outcomes in both subjects (Math +.11 SD, ELA +.09 SD). → Jordan Gutterman 2026

Jordan Gutterman, Ashish Gurung, Lee Branstetter, Kenneth Koedinger, and Vincent Aleven. (2026). Cross-Subject Predictive Validity for Learning Outcomes of Delayed Start Behavior. https://arxiv.org/abs/2606.25308 doi:10.48550/arxiv.2606.25308

q2 · i? · associational · r2

Session-level regression analysis (Table 2) on the 711-student iReady sample: total time on task showed positive effects of "+.11 SD" in math (p<.001) and +.09 SD in ELA (p=.001).

"There were also effects for outcomes in other session-level metrics: total time in the DLP (Math = +.11 SD, ELA = +.09 SD) and relative delayed start accounting for classroom-level effects (Math = -.13, ELA = -.15)."

Discussion¶

Learner Variables¶

Time and Continuity — predictor: learners who differ on it differ in outcomes

Thoughtfully designed expanded learning time and opportunities are associated with positive academic and nonacademic outcomes, with the best-designed studies showing the strongest effects — the general claim this finding bears on, with the studies behind it
Delayed start during math practice predicts standardized math test performance (β=-.07 SD, p=.02) — related
Classroom-relativized delayed start shows stronger predictive power and model fit than raw minutes, especially for ELA outcomes — related
Delayed start during math practice predicts standardized ELA test performance (β=.10 SD, p<.001) — related
Early starters (<5 min delay) show greater outcome growth while chronic delayers (>13 min) show negative trends relative to regular starters — related
Sensitivity analysis finds outcome gains significant at cut-points below 5 minutes and beyond 13-15 minutes of delayed start in both subjects — related
