Subclaims¶

q3 i? Calibration accuracy on German and Math exams did not change statistically detectably from pre-test to post-test, and intervention group did not impact this. → Nederhand 2020

Evidence¶

Nederhand 2020¶

Nederhand, M. L., Tabbers, H. K., Jongerling, J., & Rikers, R. M. J. P. (2020). Reflection on exam grades to improve calibration of secondary school students: a longitudinal study. Metacognition and Learning. https://doi.org/10.1007/s11409-020-09233-9

q3 · i? · causal · r2

Pre-test/post-test comparison in two non-intervention courses (German and Math) administered to all intervention groups at the beginning and end of the intervention period, analyzed with two-level models. The article reports no statistically detectable change, "all t’s<2".

"Results showed that calibration accuracy on the German and Math exams did not change statistically detectable from pre-test to post-test (pretest: MGer =1 . 1 5 ,SDGer = 0.77; MMath = 1.25, SDMath = 0.96; post-test: MGer =1 . 0 3 ,SDGer = 0.80; MMath =1 . 1 9 , SDMath = 0.89), all t’s<2 ."

Discussion¶

Related Claims¶

• Secondary students' French exam performance improved over the school year, but this improvement was not attributable to the intervention groups — related
• Providing grade estimates after each exam improved secondary students' calibration accuracy over a school year, regardless of the level of reflection support — related
• The level of reflection support (practice-only, grade comparison, or reflection prompts) did not differentially affect the improvement of secondary students' calibration accuracy over time — related
• Among secondary school students, calibration accuracy is unrelated to confidence in performance estimates across French, Math, and German exams — related
• Students in the Reflection condition became more confident in their grade estimates over the school year, unlike students in the Practice and Grade comparison conditions — related
