Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Simulated action logs composed of a single action type show "answer requested" produces the lowest average probability of correct end-of-unit responses, lower than "wrong response". → Lu 2024

q2 · i? · the article prints no effect size for this finding · design · r2
Simulation with artificial action logs built from the top 100 popular in-unit problems, using Model 1 without action features and student/class embeddings (Figure 3). "Correct response" gave the highest and "open response" the second-highest average probability.
"Conversely, the action type “answer requested” results in the lowest average probability, even lower than that of “wrong response.”"
Discussion¶
Related Claims¶
- A wrong response preceding a help request is associated with a higher predicted probability of a correct end-of-unit response than the request alone — related
- NCA scores of IIU input vectors order action types identically to the main-effects ordering (Spearman's ρ = 1) — related
- Single instances of help-seeking actions (answer requested, explanation requested) carry more predictive information than single correct or open responses (ISA) — related
