Subclaims¶

q3 i2 The rubric group perceived forming self-assessments as easier than the control group (d = 0.52), while mental effort did not differ (d = 0.16). → Rebecca Krebs 2022

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

Subjective cognitive load rated on 7-point mental effort and perceived difficulty scales after self-assessment in the N = 93 experiment. "The rubric group perceived forming the self-assessments as easier than the control group"; mental effort did not differ.

"In terms of perceived difficulty, a t test indicated a statistically significant effect, t(90) = -2.45, p = 0.016, d = 0.52. The rubric group perceived forming the self-assessments as easier than the control group. By contrast, in terms of mental effort, we did not find a statistically significant difference between the two groups, t(90) = -0.77, p = 0.444, d = 0.16."

Discussion¶

Related Claims¶

• Providing a rubric reduces bias in self-assessment, moving judgments closer to expert ratings — related
• Invested mental effort and perceived task difficulty are strongly correlated yet relate differently to relative task difficulty, indicating the two ratings measure different aspects of overall cognitive load — related
• Expert example standards increase subjective task difficulty and mental effort during example evaluation — related
