The Lexile Framework Training Module

1. The Lexile Framework Training Module

2. The Lexile Framework is a scientific approach to reading measurement that matches readersto text. The Lexile Framework measures both reader ability and text difficulty on the same scale, called the Lexile scale.

3. What is a Lexile? A Lexile is a unit for measuring text difficulty. The word Lexile is a blend of the root word ”Lex”, which refers to words, and echoes the word “percentile”, a comparative unit of measure. The Lexile Framework is a system of measurement that quickly calibrates the difficulty of most any textual material with a high degree of accuracy.

4. The Lexile Framework Variables Syntactic Complexity • the number of words per sentence • longer sentences are more complex and require more short term memory to process Semantic Difficulty • the frequency of the words in a corpus of written text • corpus has over 500-million words

5. Syntactic Complexity • The best predictor of the difficulty of a sentence is its length. • Longer sentences are likely to contain more clauses, and therefore to communicate not only more information and ideas but an interrelationship between them. • Longer sentences require the reader to retain more in short-term memory in order to negotiate meaning.

6. Semantic Difficulty • The difficulty of words is a continuum based on exposure. • Knowing the frequency of words provides the the best means of inferring whether a word will become a part of an individual’s vocabulary.

7. Lexile Measures • SRI Test results are reported in Lexiles • The Lexile Number indicates 75% comprehension • Books have Lexile Measures • Match students and books, and plan instruction with Lexile Ranges

8. Use Lexiles To: • To promote reading progress • To assign the right level of reading materials in all curricular areas • As a flexible part of any reading program • Connect students to tens of thousands of books • Connect students to tens of millions of articles

9. The Lexile Map • An educational tool that links text and readers under a common metric, Lexiles • Characterizes reader with a measure and text with a measure • Allows educators to forecast the level of comprehension a reader is expected to experience with a particular text

11. Classroom Uses • Develop individualized reading lists • Enhance thematic teaching • Use as a tool for sequencing materials • Develop a take home reading folder • Adjust level of reading for special circumstances • Assist in informed choice making for students

12. Lexile Facts • Over 450 book publishers have titles with Lexile measures • Nearly 50,000 books to search at www.lexile.com • Over 70 million Lexiled articles through database-services partners

13. The Lexile Calculator Forecasted Comprehension • The relationship between a reader and a text. • How well the reader will comprehend the material in the text. Can perform the following calculations • The rate at which a student is expected to comprehend of the text. • The reading ability a reader is expected to need in order to comprehend the text at a specific level.

15. Forecasted Comprehension Rates • Reader measure – text calibration = +250 Lexiles, 90% comprehension • Reader measure – text calibration = O Lexiles, 75% comprehension • Reader measure – text calibration = 250 Lexiles, 50% comprehension

16. Lexiles give educators the confidence to choose materials that will improve student reading skills across the curriculum and at home.
