q2 i? MANOVA showed significant differences between the ART and T3 groups for intervention story content, and a significant difference for T3 on story quality. → Dunn 2013

q2 · i? · causal · r1

Randomized control trial analysis of 12 fourth-graders assigned to ART, T3, or control groups; probe scores were compared with paired-samples t-tests and MANOVA at a .25 alpha level given the small sample. The article reports "significant differences computed amongst groups" for story content and for T3's story quality; no effect size accompanies this test.

"Significant differences computed amongst groups resulted between ART (Dunn & Finley, 2008) and T3 (Katahira, 2012) for intervention story content; T3 also had a significant difference for story quality."

• ART students achieved larger effect sizes for story content (1.46) and number of words written (.95), while T3 students achieved the largest effect size for story quality (1.13) — related
• T3's comparatively small story-content effect is attributed to its lack of specific story-content cue questions, while verbalizing aloud during pre-writing helped story quality — related
