Text-based Vocabulary Intervention Training Study: Supporting Fourth Graders with Low Reading Comprehension and Learning Disabilities.

This experimental study examined the effectiveness of a text-based reading and vocabulary intervention with self-regulatory supports for 4 graders with low reading comprehension. Students with standard scores on the Gates MacGinitie Reading Test between 1.0 standard deviation (SD) and 0.5 SD below the normative sample were included (N=44) and randomly assigned to treatment condition (n=25) or no treatment comparison condition (n=19). Researchers provided the intervention to students in groups of approximately 2-3 students for eight 30 minute sessions. Students in the treatment condition made statistically significant gains on a researcher-developed measure of reading and vocabulary compared with students in the comparison condition.
