The Effectiveness of a Program to Accelerate Vocabulary Development in Kindergarten
REL Southeast conducted a randomized control trial in the Mississippi Delta to test the impact of a kindergarten vocabulary instruction program on students’ expressive vocabulary — the words students understand well enough to use in speaking. The study found that the 24-week K-PAVE program had a significant positive impact on students’ vocabulary development and academic knowledge and on the vocabulary and comprehension support that teachers provided during book read-alouds and other instructional time.
