Research of Importance to All Educators
By Linda Farrell, Marcia Davidson, Michael Hunter and Tina Osenga
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 based on the widely accepted view that reading has two basic components: word recognition (decoding) and comprehension. The Simple View formula has been supported and validated by a number of research studies. Understanding the formula can 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)
