Winners of the 2nd CSEDM Data Challenge

We are pleased to announce the winners of the 2nd CSEDM Data Challenge! They bring home a collective prize pool of $1,500, sponsored by a generous donation of the Prof. Ram Kumar Memorial Foundation through the International Educational Data Mining Society (IEDMS).

Phase 1: Congratulations to teams BDAA-BASE, and UIUC, who respectively achieved first and second place in Track 1 (Knowledge Tracing) and Track 2 (Early Grade Prediction)

Phase 2: Congratulations to both teams: BDAA-BASE and TAL-JNU, who achieved first place in Track 1 and Track 2, respectively. They each also achieved 2nd place in the opposite track!

In Track 1 (Knowledge Tracing), the top submission achieved an AUC of 79.2% for cross-semester prediction, and 80.1% for within-semester prediction, outperforming our baseline by over 4% (a sizable margin for knowledge tracing tasks).

In Track 2 (Early Grade Prediction), the top submission achieved an RMSE of 15.3% RMSE for cross-semester prediction, which improved to 12.7% for within-semester prediction. This suggests that programming data alone can predict students' grades on a paper final exam with an average accuracy within almost one grade letter!
