Rebecca Krebs, Björn Rothstein, Julian Roelle. (2022). Rubrics enhance accuracy and reduce cognitive load in self-assessment. Metacognition and Learning. https://doi.org/10.1007/s11409-022-09302-1

q3 · i2 · causal · r2

Same randomized experiment (N = 93) measuring signed difference between student and expert ratings. "the rubric group's bias scores were closer to zero", d = 0.52, p = 0.008 (one-sided).

"Both groups showed underconfidence, but the rubric group's assessments were less biased than the control group's assessments, that is, the rubric group's bias scores were closer to zero, t(90) = 2.46, p = 0.008 (one-sided), d = 0.52."
