Subclaims¶

q2 i? Place-value strategy frequencies across five questions differed from random selection expectations, though the chi-square test was only marginal. → Adesina 2014 q2 i? The tool appeared to detect strategic groupings among students, with about half using place-value once or not at all. → Adesina 2014 (2)

Evidence¶

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

q2 · i? · design · r2

Goodness-of-fit analysis of MuTAT pairing data for 39 children across five study questions; observed place-value frequencies were 3, 18, 14, 14 and 23 against an expected 13 per strategy. The test was "significant but marginal".

"A one‐sample chi‐square test was significant but marginal, χ 2 (4, N=39) =9.58, p=.048, suggesting that some but not all of the students were working strategically."

q2 · i? · design · r2

Descriptive analysis of Table 3 usage counts: about half the students (20) used place-value once or not at all, and of the 20 who used it once or not at all, 9 used mostly the as-presented strategy. The authors hedge with "may have detected".

"This suggests the MuTAT application may have detected strategic groupings amongst the students between those who selected the numbers as presented and those who were more strategic."
