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? Curriculum-based approaches alone are not the best influence on reducing food consumption or energy intake, with a minimal mean effect size of Md = 0.12. → Dudley 2015
q2 i? Curriculum-based approaches improved nutritional knowledge with Md = 0.75 and FV consumption or preference with Md = 0.45, both within the Zone of Desired Effects. → Dudley 2015 (2)
Evidence¶
Dudley 2015¶
Dudley, D. A., Cotton, W. G., & Peralta, L. R. (2015). Teaching approaches and strategies that promote healthy eating in primary school children: a systematic review and meta-analysis. International Journal of Behavioral Nutrition and Physical Activity, 12, 28. https://doi.org/10.1186/s12966-015-0182-8
q2 · i? · quant-synthesis · r?
Meta-analysis of curriculum-based approaches across eleven studies reporting food consumption and energy intake; effect sizes were calculable for six outcomes, four showing minimal or no effect, one negative, one small. The review reports a mean Cohen's d of Md = 0.12.
"The mean effect size of curriculum-based approaches is minimal (Md = 0.12) and would suggest that curriculum-based approaches alone are not the best influence on reducing food consumption or energy intake."
Dudley 2015 (2)¶

q2 · i? · quant-synthesis · r2
Meta-analysis of curriculum-based approaches: 12 studies for nutritional knowledge (Md = 0.75, with 8 of 13 outcomes significant at p < .001) and 30 calculated FV effect sizes (33% medium-to-large). The review reports a mean Cohen's d of Md = 0.45 for FV outcomes.
"The mean effect size for curriculum-based approaches was Md = 0.45 indicating that having a nutrition curriculum delivered in primary schools makes an important investment in improving FV consumption or preference based on the educational hinge-point of effect sizes described by Hattie [11]."
Discussion¶
Learner Variables¶
- Physical Well-Being — outcome: instruction changes it
