Subclaims¶

q2 i? In the first period, the difference in numbers of answers between Group A (clickers) and Group B (non-clickers) was not statistically significant. → Unal Cakiroglu 2018 q2 i? In the second period, the difference in numbers of answers between the groups, with roles swapped, was also not statistically significant. → Unal Cakiroglu 2018 (2)

Evidence¶

Unal Cakiroglu 2018¶

Unal Cakiroglu, Fatih Erdogdu, Seyfullah Gokoglu. (2018). Clickers in EFL Classrooms: Evidence from Two Different Uses. Contemporary Educational Technology, 9(2), 171-185. https://doi.org/10.30935/cet.414820

q2 · i? · causal · r1

Non-parametric Mann-Whitney test comparing the two groups (n = 10 each) in the first period, reported in Table 1. The article reports "U=28.00, p>0.05" but notes Group A (using clickers) seemed to respond more by sum of ranks; equivalence was not tested.

"there is no significant differences between the numbers of answers given by the Group A and B during first period ( U=28.00, p>0.05)."

q2 · i? · causal · r1

Mann-Whitney test for the second period, reported in Table 2 with "U=35.00, p>0.05"; by sum of ranks Group B (using clickers) seemed to respond more than Group A. No effect size is printed.

"there is no significant differences between the numbers of answers given by the Group A and B during second period ( U=35.00, p>0.05)."
