This report compares features of the words in fourth grade ELA and science texts and suggests instructional methods suitable to the vocabulary in each type of text.

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.

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.

The purpose of this review is to examine the function, logic, and impact of qualitative systems, with a focus on understanding their benefits and imperfections.
