The link above will take you to an introduction to the Simple View of Reading.
The Simple View of Reading is a formula demonstrating the widely accepted view that reading has two basic components: word recognition (decoding) and language comprehension. Research studies show that a student’s reading comprehension score can be predicted if decoding skills and language comprehension abilities are known.
In spite of its importance in the world of reading research, many practicing educators do not know about the Simple View of Reading. It is a formula demonstrating the widely accepted view that reading has two basic components: word recognition (decoding) and language comprehension. The Simple View formula has been supported and validated by a number of research studies. Understanding the formula will help educators with assessing reading weaknesses and providing appropriate instruction.
The Simple View formula presented by Gough and Tunmer in 1986 is:
Decoding (D) x Language Comprehension (LC) = Reading Comprehension (RC)
The Simple View formula and supporting studies show that a student’s reading comprehension (RC) score can be predicted if decoding (D) skills and language comprehension (LC) abilities are known. Notice that D and LC are not added together to predict RC. They are multiplied. In the Simple View formula, the values of D and LC must be between 0 and 1 (or 0% and 100%). A score of 0 means no skill or ability at all and 1 indicates perfection. (Examples of how the formula works can be found by clicking on the link above).
