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? Using the Digit Letter Substitution test, van den Berg et al. found no significant effect of a living plants classroom wall, while van Dijk-Wesselius et al. reported a significant positive effect of a greened schoolyard. → Dianne A. Vella-Brodrick · Krystyna Gilowska 2022

q2 · i? · review · r3
The review reports these two long-term-exposure quasi-experiments with the Digit Letter Substitution test, in which participants convert digits to letters against a key within short time periods. The review attributes the inconsistency either to true inconsistency of nature exposure or to difficulty establishing causal effects for long-term studies.
"No significant positive effect was found on processing speed in the living plants classroom wall exposure study in Dutch primary school children (van den Berg et al., 2017). However, a significant positive effect was reported in the Greening of School study in Dutch school children aged 7–11 years (van Dijk-Wesselius et al., 2018)."
Discussion¶
Learner Variables¶
- Processing Speed — outcome: instruction changes it
