q2 i? Only one study demonstrated an overall negative effect size, with small negative effects for the high-DCF and low-ICF groups, a medium negative effect for the low-DCF group, and a large negative effect for the high-ICF group. → Albatool Abalkheel & Tara Brandenburg 2020

q2 · i? · quant-synthesis · r1

Meta-analysis result for Van Beuningen et al. (2011), a 268-student study in four Dutch secondary schools comparing DCF, ICF, and control conditions over 6 weeks, measured by overall accuracy of writing (Table 2 reports negative Cohen's d values for all groups).

"Only one study demonstrated an overall negative effect size (Van Bueningen et al., 2011) with a small negative effect with the high-DCF group and the low- ICF group, a medium negativ e effect for the low-DCF group and a large negative effect size for the high-ICF."
