Subclaims¶

q2 i? The video group (mean 5.73) scored marginally higher than the text/image group (mean 5.29) on the main test, with a t-test significant at p<0.1 but not at p<0.05. → Milosevic 2017 q2 i? The video group wrote longer, more elaborate answers to the comprehension questions than the text/image group. → Milosevic 2017 (2)

Evidence¶

Milosevic 2017¶

Milosevic, D. (2017). Using video materials in English for technical sciences: a case study. In C. Sarré & S. Whyte (Eds), New developments in ESP teaching and learning research (pp. 15-30). Research-publishing.net. https://doi.org/10.14705/rpnet.2017.cssw2017.743

q2 · i? · causal · r1

Quasi-experimental comparison of two intact groups of first-year ESP students (video N=27, text N=26) after a single 10-minute exposure. The t-test reached only the p<0.1 level, which the author describes as a "marginal advantage for the video group".

"A t-test performed on these group means is significant at p˂0.1 (not the more commonly accepted p 0.05 level), suggesting a marginal advantage for the video group."

q2 · i? · causal · r1

Descriptive comparison of average words per answer across four comprehension items (video group means 2.74, 1.37, 1.56, 2.89; text group means 1.5, 2.23, 1.08, 2.12). The video group "wrote longer, more elaborate answers" on three of four items.

"This finding is supported by measures of average length of responses: the video group wrote longer, more elaborate answers to the questions in the comprehension exercise, as shown in Table 3."
