"The one subscale where the TG did not achieve significant gains over the CG was organization."

Related Claims¶

• EFL learners in an enhanced extensive reading treatment group significantly outperform a control group on five of six writing subscales — possibly the same claim (merge candidate)
• Both the treatment and control groups achieved significant pre-to-post gains on all six writing subscales — related
• Enhanced extensive reading yields small-to-large effect sizes across writing subscales, with the largest effects in spelling/mechanics and fluency — related
