Subclaims¶

q3 i? Between-group one-way ANOVAs at each time point showed no differences among the three groups in production (pretest F(2, 39) = 0.95, p = 0.392; posttest F(2, 39) = 0.90, p = 0.413) or perception (pretest F(2, 39) = 1.57, p = 0.221; posttest F(2, 39) = 0.32, p = 0.731). → Liakin et al. 2015

Evidence¶

Liakin et al. 2015¶

Denis Liakin, Walcir Cardoso and Natallia Liakina. (2015). Learning L2 pronunciation with a mobile speech recognizer: French /y/. CALICO Journal 32.1. https://doi.org/10.1558/cj.v32i1.25962

q3 · i? · causal · r2

One-way ANOVAs comparing the three experimental groups at pretest and posttest on both measures; all four tests non-significant. The article's note explains the ASR group's large within-group variability and lower pretest mean as contributing factors.

"the results of the one-way ANOV A indicated no differences among the three groups either on the pretest or the posttest in both /y/ production (F (2, 39) = 0.95, p = 0.392 and F (2, 39) = 0.90, p = 0.413 in pre- and posttest respectively) and /y/ perception (F (2, 39) = 1.57, p = 0.221 and F (2, 39) = 0.32, p = 0.731 in pre- and posttest respectively)."

Discussion¶

Related Claims¶

• No group improved in perception of French /y/, so production-focused ASR training did not transfer to perception — related
• The three groups were equivalent on EPT pre-test scores before the intervention — related
• A one-way ANOVA found no significant difference in writing proficiency among the five pre-test groups — related
