Subclaims¶

q3 i? On delayed posttests, the metalinguistic group was significantly more accurate than both the recast and control groups on new (untreated) verb items in the oral imitation test, and more accurate than the recast group on new items in the grammaticality judgment test. → Rod Ellis 2006

q3 · i? · causal · r1

ANCOVA on oral imitation new-item scores (verbs not receiving feedback) at delayed posttest, n = 34. "the metalinguistic group is significantly more accurate than both the recast and control groups"; GJT new items also favored metalinguistic over recast (F = 4.295, p < .05).

"there were differences on the delayed posttest, F (2, 34) = 8.943, p < .01. The post hoc contrasts show that the metalinguistic group is significantly more accurate than both the recast and control groups."
