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? For question 6, the lower bound of the probability of sufficiency of feedback help for a 0D answer is 0.94, and skill-level 1D is likely necessary for answers above 0D complexity, indicating the question discriminates algorithmic skill levels well. → Francesca Mangili 2026

q2 · i? · theoretical · r3
Group-level counterfactual inference (generalised probabilities of necessity and sufficiency) computed via twin networks over the compatible FSCMs for the CAT assessment with 109 students, reported in Table 2. Some intervals are wide (e.g. PN of S_alg=1D for Q6=1D between 0.11 and 0.95), but most inferences are informative.
"the lower bound of the probability of sufficiency ofH 6 = feedbackforQ 6 = 0Dis 0.94, meaning that providing a blank cross-array and visual feedback is very likely to enable a student to solve the task with at least a 0D algorithm, regardless of their skill level."
Discussion¶
Related Claims¶
- Group-level marginal inferences identify population propensity and autonomy but are nearly vacuous for higher algorithmic skill levels — related
- Individualised counterfactual inferences estimate whether a specific student would have performed differently under different help conditions — related
- Marginal luck probabilities diagnose question calibration, flagging questions 7–9 as prone to over-performance and question 12 as particularly challenging — related
- Formalisation of theory offers generative models, counterfactual reasoning, and optimal-performance yardsticks unavailable to verbal accounts — a broader claim this one bears on
