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? A marginally reported finding of the hierarchy study was that no group effects were found; the non-significant intra-group correlation suggested group membership had no specific influence on individuals' learning and performance. → Cress 2015
Evidence¶
Cress 2015¶
Cress, U., Stahl, G., Ludvigsen, S., & Law, N. (2015). The core features of CSCL: Social situation, collaborative knowledge processes and their design. International Journal of Computer-Supported Collaborative Learning, 10, 109-116. https://doi.org/10.1007/s11412-015-9214-2
q2 · i? · review · r2
The editors report this null finding from the Rhem et al. study as marginal; equivalence was not tested, and no effect size is printed.
"The non-significant intra-group correlation seems to express that the different groups did not have any specific influence on people ’s learning and performance."
