Oregon Department of Education www.ode.state.or.us Module I Lexile Calculator Can forecast comprehension Identifies the relationship between the reader and the text Predicts 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 The Lexile Calculator is a tool to calculate expected comprehension at various Lexile measures. We know that students are less successful when reading text that is more difficult (higher Lexile measure) than their reading ability (Lexile measure). The Calculator enables the teacher to predict, or forecast, the expected comprehension rate for a student when the student reads material that is above or below his/her reading ability.

Oregon Department of Education www.ode.state.or.us Module I Lexile Calculator The x axis represents the difference (in Lexiles) between the reader measure (Lexile) and the text measure (Lexile). You should read the label for the x axis as “reader minus text” to yield a Lexile differential. The y axis represents the forecasted comprehension rate recorded as a percentage. If you know a student’s Lexile measure and the Lexile measure for a text, you can use the Calculator to predict the comprehension rate for the student on that text.

Oregon Department of Education www.ode.state.or.us Module I Lexile Calculator  The X marks the spot where there is no difference between the Lexile measure of the reader and the Lexile measure of the text. It intersects with the forecasted comprehension rate of 75%. So a reader with a Lexile measure of 600L who is asked to read a text measured at 600L is expected to have a 75-percent comprehension rate. But what would the comprehension rate be if this same reader were given a text measured at 350L or one at 850L? It is the difference in Lexiles between reader and text that governs comprehension. Do not confuse comprehension rate with accuracy rate. At a 75% comprehension rate the reader is reading with enough accuracy and fluency to make sense of the text (comprehend what is being read) and acquire new vocabulary. This is the target comprehension rate and the basis from which all Lexile calculations are made. Training modules developed by an ESD/OEMA/OSL/ODE Collaborative Posted July 2005

Oregon Department of Education www.ode.state.or.us Module I Lexile Calculator Formula for the X axis: Reader measure – Text measure = Lexiles Examples: Reader (1230L) – Text (890L) = 340 L Reader (890L) – Text (1230L) = -340 L minus The Lexile Calculator shows the relationship between a reader and a text, identifying how well the reader will comprehend the material in the text. Whenever the Lexile measure of the text is higher than the Lexile measure of the reader, the Lexile differential is recorded as a negative number.

Forecasted Comprehension Rates Oregon Department of Education www.ode.state.or.us Module I Forecasted Comprehension Rates Reader measure – text calibration = O Lexiles 75% comprehension rate Reader measure – text calibration = -250 Lexiles 50% comprehension rate Reader measure – text calibration = +250 Lexiles 90% comprehension rate You can see the fluctuation in comprehension rate when the text is at a higher or lower Lexile than that of the reader.

Lexile Measure Required to Meet Comprehension Rate Oregon Department of Education www.ode.state.or.us Lexile Measure Required to Meet Comprehension Rate Module I Calculator Results In order for a student class to comprehend the Grade 7 "Book Bag" with a comprehension rate between 85% and 90%, the students would be expected to have an ability between 1015 and 1100 Lexiles. This may be a good time to pause and ask participants to forecast the comprehension rate for each of the Lexile groupings they created for their own classrooms earlier in the workshop. If you have connectivity to the Internet, you may wish to demonstrate the calculator using information suggested by participants. Another possible point of discussion would be to revisit the Lexile ranges for independent reading and instructional reading.
