A Comparison of the Effects of Two Phonetically Regular Text Types on Young English Learners’ Literacy

Long after Chall (1967/1983) described the choice of reading pedagogy for beginning reading as “the great debate,” the topic of the kinds of texts that best support beginning readers continues to generate controversy (Allington, 1997; Beck, 1997).

Growing Capacity with the Vocabulary of English Language Arts Programs: Vocabulary Megaclusters

The typical approach to teaching vocabulary in English/Language Arts programs has been to focus on six to eight words per text. Even though these words may add meaning to a particular story, the target words are often rare and their generalizability is limited. The Vocabulary Megaclusters provides a framework for selecting and teaching words according to their shared meaning and function in stories.

Using Multiple Sources of Information in Establishing Text Complexity

The Common Core State Standards/English Language Arts use Lexiles as the single measure of text complexity, but an analysis using the two component measures of Lexiles along with a third measure suggests that conclusions about text complexity vary considerably when multiple quantitative measures are used, rather than a single, omnibus index.
