q2 i? Fixed High reaches only 59% independence and Linear Decay 71%, while ARPG+ adaptive fading achieves higher independence (91% per abstract) with periodic reinforcement implementing the spacing effect. → Ye 2026

q2 · i? · causal · r?

Scaffolding strategy effectiveness analysis comparing Fixed High (constant σt = 5), Linear Decay (uniform reduction to 0.25), and ARPG+ Adaptive (dynamic adjustment with reinforcement at Turns 5, 10, 15). The text is truncated at "ARPG+ achieve"; the abstract reports 91% independence versus 59% under fixed support.

"Fixed High reaches only 59% independence, Linear Decay 71%, while ARPG+ achieve"
