 We know that oral language predicts comprehension scores in later grades. Catts, Fey, Zhang, & Tomblin, (1999) found phonological awareness and rapid naming predicted the most variance in  reading comprehension scores of second graders. However language skills explained an additional 13.8% of the variance.
-In fact in third grade reading accuracy and reading comprehension begin to split in measures of overall reading. Decoding skills predict reading accuracy while oral language skills (defined as vocabulary and background knowledge) explain the variance in comprehension scores (Storch and Whitehurst, 2002).

+===== Oral Language and Vocabulary =====
+Studies show a relationship between oral language development and vocabulary. Hart and Risley proposed the four million word gap in their research on vocabulary and oral language development. More recent work has challenged the size of the "gap" and under lying principles in the study but everyone agrees greater and more complex talk improves vocabulary acquisition. Assessments of knowledge using vocabulary measures are highly correlated with comprehension measure.
+This has lead to researchers calling for a renewed focus on building background knowledge and focusing on academic language acquisition (Nueman, 2006 Tabors, Roach, & Snow, 2001).
