Subclaims¶

q2 i0 At the beginning of the experiment the groups' pre-test results were not statistically significant (F(1, 41) = 0.34, p = .855, partial η2 = .001). → Balaman 2018 q2 i3 At post-test the experimental group outperformed the control group (F(1, 41) = 38.843, p < .001, partial η2 = .486; MD = 6.75). → Balaman 2018 (2)

Evidence¶

Balaman 2018¶

Balaman, S. (2018). Digital storytelling: A multimodal narrative writing genre. Journal of Language and Linguistic Studies, 14(3), 202-212. https://eric.ed.gov/?id=EJ1193109

q2 · i0 · causal · r1

Between-group comparison of pre-test writing scores in the 2×2 mixed design. The article reports the pre-test difference was "not statistically significant" with partial η2 = .001, indicating equivalent starting proficiency.

"at the beginning of the experiment , both groups’ pre-test results were not statistically significant, F (1, 41) = 0.34, p = .855, partial η2 = .001"

Balaman 2018 (2)¶

q2 · i3 · causal · r2

Between-group comparison of post-test writing scores. The article states "the experimental group outperformed the control group at the post-test writing scores" with partial η2 = .486 and MD = 6.75.

"at the post-test, there was a significant difference between the control and the experimental groups’ writing scores, F (1, 41) = 38.843, p < .001, partial η2 = .486"
