q2 · i? · design · r2

Simulation-based evaluation using KT2 to simulate multi-round practice and score a fixed exam set; Table 1 reports exam scores per module, where "KT4EQG achieves the highest exam score across all modules". INITIAL, RANDOM, and ORACLE baselines were excluded from the ranking.

"Table 1 shows the performance of all methods across all knowledge modules in XES3G5M and MOOCRADAR. KT4EQG achieves the highest exam score across all modules, consistently outperforming all question-generation baselines."

Related Claims¶

• Providing baselines with oracle knowledge-concept selection substantially improves their performance, identifying concept selection as a key bottleneck, though baselines with oracle KCs still trail KT4EQG — related
• KT4EQG achieves the highest exam score across all practice-round counts, while methods without effective concept selection show only marginal gains as rounds increase — related
• KT4EQG remains competitive when evaluated with alternative knowledge tracers (BKT and DKT), though its advantage varies across modules — related
• KT4EQG's education-value objective produces an adaptive KC-selection policy: weaker students are given better-mastered concepts and stronger students progressively more challenging ones — related
