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 i2 In a March 2010 study, students with adaptive dialogues outperformed peers with non-adaptive dialogs, effect size 0.69 on learning gains after approximately 100 minutes of interaction. → Antonija Mitrovic & Pramuditha Suraweera 2016

q2 · i2 · causal · r?
A study of adaptive tutorial dialogues in EER-Tutor where dialogs are selected based on the student model and individualized by adaptation rules. The article reports "the effect size 0.69 on learning gains" and notes the only difference between groups was dialogue adaptivity.
"In a study conducted in March 2010, the students who had adaptive dialogs outperformed their peers who only received non-adaptive dialogs, with the effect size 0.69 on learning gains after approximately 100 min of interaction with the system (Weerasinghe et al. 2010)."
