q2 i? In one SeniorH student's sequence, a correlated concept's state increased without direct practice, while frequent domain switching preceded failure on a previously well-trained concept. → Haotian Zhang 2026

q2 · i? · design · r2

Qualitative case study (Figure 5) of a SeniorH student's cross-domain knowledge state evolution; the model assigned an increased state to c3 based on mastery of correlated c2, and the student failed q11 after frequent domain switching, showing that "cognitive load can weaken immediate learning gains".

"This indicates that cognitive load can weaken immediate learning gains even for pre- viously well-trained concepts. Overall, this case study provides intuitive evidence that LT-MKT can jointly model beneficial knowl- edge transfer and load-induced learning friction."
