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 i3 Operation ARA evaluations reported learning gains of 1.4 σ on a test of scientific research skills versus no-instruction controls, with students using ARA between 8 and 12 h. → Nye 2014 q2 i2 MetaTutor reported higher learning efficiency (0.84 σ) when tutors assisted students with prompts and feedback, but learning efficiency was approximately equal after considering the entire time spent using the system. → Nye 2014 (2)

Review reports Operation ARA/ARIES serious-game evaluations for scientific inquiry skills; students used ARA between 8 and 12 h with game-narrative motivational features. Printed effect size: 1.4 σ versus no-instruction controls.

"evaluations of Operation ARA reported learning gains of 1.4 σ on a test of scientific research skills when comp ared with controls who received no instruction (Halpern et al. 2012)"

Review reports the MetaTutor hypermedia biology evaluation with agent prompts and feedback. Printed effect size: 0.84 σ learning efficiency counting only material-interaction time; approximately equal when total system time was counted.
