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? In a fully crossed quasi-experiment manipulating incentives and reflection in a college course, incentives significantly improved calibration accuracy but only among lower-achieving students. → Bol L and Hacker DJ 2012

q2 · i? · theoretical · r3
Quasi-experiment in college courses (Hacker et al., 2008a) with a fully crossed incentives-by-reflection design; extrinsic reward students could earn one to four additional points per exam for calibration accuracy. The article reports "incentives significantly improved calibration accuracy but only among lower-achieving students"; no effect size is printed.
"In another more ecologically valid study, we manipulated incentives and reflection in a fully crossed quasi-experiment conducted in college course (Hacker et al., 2008a). Students in an extrinsic reward condition were told they would receive one to four additional points on each of three exams, depending on their calibration accuracy, with more points given for greater accuracy. We found that incentives significantly improved calibration accuracy but only among lower-achieving students"
Discussion¶
Related Claims¶
- 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
- 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
