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? Suburban participants increased knowledge significantly (V = 25.50, P = 0.005), while urban (P = 0.309) and rural (P = 0.964) participants did not, and no school level showed a significant increase. → Florence Martin 2025

q2 · i? · design · r2
Wilcoxon signed-rank subgroup analyses by district type and school level in the 50-participant PD evaluation. The quote reports the significant suburban result and non-significant urban and rural results; the article separately reports no significant increase for elementary, middle, or high school levels.
"participants from suburban areas increased their knowledge significantly (V = 25.50, P = 0.005 < 0.05), while those from urban (V = 30.50, P = 0.309 > 0.05) and rural areas (V = 34.00, P = 0.964 > 0.05) did not."
Discussion¶
Related Claims¶
- Knowledge gains from the cybersecurity PD differed by technology background: participants without a technology background improved significantly while those with one did not — related
- Mentoring experiences did not differ statistically significantly across districts with different poverty, achievement, or rurality levels — related
- Rural and urban TECTA participants showed no statistically significant differences in credential attainment or time to completion — related
- Knowledge gains were concentrated in module 2 and the awareness dimension: ask and action knowledge remained unchanged after the PD — related
