Evidence

Mitrovic 2015

Mitrovic, A., & Ohlsson, S. (2015). Implementing CBM: SQL-Tutor After Fifteen Years. International Journal of Artificial Intelligence in Education. https://doi.org/10.1007/s40593-015-0049-9

q2 · i? · design · r1

The article reports that SQL-Tutor originally provided only negative feedback on errors, and cites Mitrovic et al. (2013) on the effect of adding positive feedback. It states students finished "in only half of the time" with equal learning improvement. No effect sizes are printed.

"when we added positive feedback, students were able to complete the same learning tasks in only half of the time while achieving the same learning improvement"
