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.
q3 i? ANOVAs with SOJ as dependent variable and performance quartile as independent variable were non-significant for university students and for secondary students in all three subjects. → Marloes L. Nederhand 2021

Marloes L. Nederhand, Huib K. Tabbers, Anique B.H. De Bruin, Remy M. J. P. Rikers. (2021). Metacognitive awareness as measured by second-order judgements among university and secondary school students. Metacognition and Learning, 16, 1-14. https://doi.org/10.1007/s11409-020-09228-6
q3 · i? · associational · r2
Replication check of Miller and Geraci (2011): students were divided into four performance quartiles and SOJs compared via ANOVA. All tests were non-significant with very small ηp2 values (e.g., ".001" for university students), contrary to the prior finding that low performers report lower confidence.
"Results were not significant: subjective confidence ratings did not differ between the performance quartiles for the university students, F(3, 251) = 0.07, MSE = 0.05, p =. 9 7 8 ,ηp2 =. 0 0 1 , n o r f o r t h e secondary school students on the courses French, F(3, 291) = 1.11, MSE =0 . 7 7 ,p =. 3 4 5 , ηp2 = .011, Math, F(3, 287) = 0.42, MSE =0 . 8 2 ,p =. 7 4 1 ,ηp2 =. 0 0 4 ,a n dG e r m a nF(3, 298) = 0.44, MSE =0 . 5 6 ,p =. 7 2 5 ,ηp2 = .004."
Discussion¶
Learner Variables¶
- Metacognition — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Among secondary school students, calibration accuracy is unrelated to confidence in performance estimates across French, Math, and German exams — related
- Among university students, poorer calibration accuracy is accompanied by lower confidence in the performance estimate, independent of performance level — reports the opposite
- The four exam-performance quartile groups differed significantly on first-unit exam scores, validating the grouping used for behavioral comparisons — related
