q2 i? Completion times differed significantly between the three strategies, and the place-value strategy showed significant time differences against the other two strategies. → Adesina 2014

Adesina, A., Stone, R., Batmaz, F., & Jones, I. (2014). Touch Arithmetic: A process‐based Computer‐Aided Assessment approach for capture of problem solving steps in the context of elementary mathematics. https://doi.org/10.1016/j.compedu.2014.06.015

One-way ANOVA F-test on MuTAT completion times by strategy was significant (F = 4.9, p = 0.01); TukeyHSD pairwise comparisons at 95% confidence followed. The authors conclude "the MuTAT application can detect the relative efficiency of strategies".

"The test revealed significant differences between the mean time of the place‐value strategy (p=0.01) and the as‐presented (p=0.13) and other (p=0.58) strategies."
