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.
q3 i3 Average independent working time per group increased significantly more in the scaffolding condition than in the nonscaffolding condition, with a large effect size. → van de Pol 2015
Evidence¶
van de Pol 2015¶
van de Pol, J., Volman, M., Oort, F., & Beishuizen, J. (2015). The effects of scaffolding in the classroom: support contingency and student independent working time in relation to student achievement, task effort and appreciation of support.

q3 · i3 · causal · r2
Repeated-measures ANOVA manipulation check on average independent working time per group; the article reports a significant interaction, F(1,22) = 11.78, p = .00, with a large printed effect size (gp2 = .35). Time rose from about 5 to about 10 minutes in the scaffolding condition.
"The results of the repeated-measures ANOVA showed that there was a significant interaction effect of condition and measurement occasion on the average independent working time for small groups ( F(1,22) = 11.78, p = .00) (Fig. 2). The effect size can be considered large; gp2 was .35"
Discussion¶
Related Claims¶
- On the knowledge assignment, neither the occasion-by-contingency interaction nor the three-way interaction with independent working time was significant — related
- Teachers who completed a scaffolding intervention program increased the contingency of their support far more than non-participating teachers — related
- Low contingent support increased task effort when independent working time was short; with long independent working time task effort decreased under both contingencies but less so with high contingency — related
- Group-level scaffolding training increases teacher process support and student participation — related
- Program teachers showed more complete cycles of contingent teaching at postmeasurement than the other teachers — related
- Groups' final solution scores were significantly higher on the scaffolded task than the non-scaffolded task — related
