q2 · i? · review · r2

Narrative review of Mongkhonvanit et al., who added video-watching features (playback speed, pause, fast-forward or rewind, completion) to DKT on MOOCs; the survey says "DKT can achieve better performance through incorporating the above binarized engagement covariates." No statistics are printed.

"Experimental results indicate that DKT can achieve better performance through incorporating the above binarized engagement covariates."

Related Claims¶

• The survey reports, citing Pavlik et al., that no single knowledge tracing model was always the best, and that a better model must consider multiple student features and the learning context. — the general claim this finding bears on, with the studies behind it
• The survey reports, citing Jung et al., that students' language proficiency as side information was effective in promoting several KT models, including DKT, DKVMN and SAKT. — related
• DKT's input/output representation significantly affects performance, with KC inputs and item outputs working best on most datasets — related
• Video-watching sequences involving pausing and rewinding are negatively correlated with math task performance in a flipped precalculus lesson — related
• The survey reports, citing Pu and Becker, that removing students' repeated interactions on the same exercises reduced AKT's performance to close to that of DKVMN. — related
