Impact of Displaying Grades Vs. Not Displaying Grades on Academic Performance and Emotional Outcomes While Delivering Feedback Comments: A Longitudinal Study

Which beliefs it touches

• C4 Task feedback vs praise sets a limit on it

  Secondary school (99 students, four intact classes, about 92 analysed): with brief comments on every task, the class that started seeing grades scored lower on the next task (5.40 vs 6.80 out of 10), and the gap was gone one task later (6.86 vs 6.73). Grades+comments vs comments, no grade-only arm, so not a kill-test of C4. Full text checked 2026-11-11.
