L EXILES EXPLAINED ( IN LESS THAN 20 MINUTES ) Jennine Bloomquist October 23, 2014
Developed by MetaMetrics, based on research funded by National Institute for Child Health Development (NICHD) An educational tool that links readers AND texts under a common designation known as Lexiles. Allows educators to forecast the level of comprehension a reader is expected to experience with a particular text. Most commonly used reading measure: Over 19 million students receive Lexile scores through commercial/state assessments Over 100,000 books and tens of millions of articles have Lexile measures The Lexile
Lexiles are based upon Semantic Difficulty (Word Frequency) Difficulty of words is based upon exposure; as a reader encounters a word again and again, it becomes more familiar. Syntactic Complexity (Sentence Length) Long sentences contain more clauses, communicate more information and ideas, require a reader to retain more information in short-term memory.
Student Lexiles vs Book Lexiles A student’s Lexile measure is a tool to use in targeting reading material for students A book’s Lexile measure is a tool for measuring the difficulty of a particular text for a particular student
Who Provides Student Lexile Measures?
It is recommended that readers choose texts within their Lexile range A Lexile range is 50L above and 100L below a student’s reported Lexile measure. A student with a 890L should choose texts to read with Lexiles between 790L and 940L. A Student’s Lexile Measure
Match a student’s reading ability with the difficulty of text material by using Lexiles A student’s Lexile is interpreted as the level of book that a student can read with 75% comprehension 75% comprehension has been identified as “offering the reader a certain amount of comfort and yet still offer a challenge” Using Lexiles
Sometimes a Lexile measure by itself is not enough information to choose a particular book for a particular reader. This is why some books get Lexile codes (for example, AD580L). AD: Adult Directed BR: Beginning Reader Only code that applies to both readers and text HL: High-Low Generally young adult IG: Illustrated Guide Usually non-fiction and reference GN: Graphic Novel NP: Non-Prose Do NOT get a Lexile Measure, only a Lexile Code NC: Non-Conforming Useful to match high-ability students with developmentally appropriate materials Lexile Codes (Books only)
Limitations of Lexile Measures Lexile text measures do NOT address Text Characteristics – Age-appropriateness of the content – Text support (e.g., pictures, pull- outs) – Text quality (i.e., Is it a good book?) Reader Characteristics – Interest and motivation – Background knowledge – Reading context and purpose Lexile text measures only measure text readability. Input from readers, parents, teachers and librarians is necessary.
Common Core State Standards Text Complexity Qualitative levels of meaning or purpose; structure; language conventionality and clarity; and knowledge demands. Quantitative those aspects of text complexity, such as word length or frequency, sentence length, and text cohesion, that are difficult if not impossible for a human reader to evaluate efficiently, especially in long texts, and are thus today typically measured by computer software. *Reader and Task considerations (i.e., student knowledge, motivation, and interests) While the prior two elements of the model focus on the inherent complexity of text, variables specific to particular readers (such as motivation, knowledge, and experiences) and to particular tasks (such as purpose and the complexity of the task assigned and the questions posed) must also be considered when determining whether a text is appropriate for a given student. Such assessments are best made by teachers employing their professional judgment, experience, and knowledge of their students and the subject. (NYSCC Appendix A, p4)
WHY DOES ALL THIS MATTER?
Grade Band“Stretch” Lexile Band K-1N/A L L L-1185L L-1335L 11-CCR1185L-1385L
Lexile Stretch Bands & College- and Career-Readiness The “stretch” bands of the Lexile Framework show an upward trajectory of reading comprehension development through the grades to indicate that all students should be reading at the college- and career-readiness level by no later than the end of high school.

Students should be ready for college and career after high school. The most important factor for readiness is a student’s ability to read and understand texts of steadily increasing complexity as they progress through school. The Lexile ® Framework provides insight into student readiness by measuring both the complexity of reading materials and a student's ability to comprehend these texts. Lexiles and the Common Core
Changes in Textbook Complexity
College and Career Readiness Skills “Furthermore, students in college are expected to read complex texts with substantially greater independence (i.e., much less scaffolding) than are students in typical K–12 programs. College students are held more accountable for what they read on their own than are most students in high school.” -Erickson & Strommer, 1991; Pritchard, Wilson, & Yamnitz, 2007
