Subclaims¶

q3 i2 When scaffolding was customized based on self-selection, effect sizes (g = 0.519) were higher than fixed time interval (g = 0.376) and performance-adaptation (g = 0.434). → Nam Ju Kim 2018

Subgroup analysis of the scaffolding customization method moderator (performance-adapted, self-selected, fixed time interval) in the Bayesian meta-analysis. The article notes few studies have investigated which customization method has the highest effects in PBL.

"When scaffolding was customized based on self-selection, the effect sizes of scaffolding were higher ( g = 0.519, 95% CrI = 0.167 to 0.989) than other scaffolding customization methods: fixed time interval (g = 0.376, 95% CrI = 0.018 to 0.713) and performance-adaption (g = 0.434, 95% CrI = 0.013 to 0.863)"
