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? The subsystem checks the validity of student-entered equations and, when an equation is not independent of a set of other equations, determines on which equations it does depend. → Joel A. Shapiro 2005

q2 · i? · design · r?
The abstract lists validity checking and dependence investigation among the subsystem's capabilities, including "determining on which equations it does depend" when an equation is not independent. No separate effect size is reported for these capabilities in the available text.
"checking the validity of equations the students enter, 3) investigating whether an equation is independent from a set of other equations, and if not, determining on which equations it does depend"
