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.
q3 i? Mean step size differed significantly between HPK (1.32) and LPK (−0.07) students in the High-Agency condition. → Xingliang Chen & Antonija Mitrovic & Moffat Mathews 2019

q3 · i? · causal · r1
Secondary analysis of High-Agency students' task selections relative to the adaptive strategy's recommended selection ('step size'). A positive step size means "a recommendation to select a more challenging preparation task"; only a U statistic is printed.
"the mean step size for the HPK students is 1.32 (sd = 1.14), while for the LPK students the mean step size is−0.07 (sd = 1.08). The difference is significant (U = 21, p =. 0 3 8 )"
Discussion¶
Related Claims¶
- The Low-Agency condition produced a significantly different mix of preparatory activities than the High-Agency condition — related
- HPK students improved significantly only in the Low-Agency condition, with a large post-test advantage over HPK peers in High-Agency (d = .95) — related
- Process mining showed LPK students began with preparatory tasks and achieved a higher proportion of correct decisions, while HPK students skipped preparation and increasingly took advanced tasks — related
