How much a student reads does matter. These statistics are from NAEP (National Assessment of Educational Progress):
1. Achievement Percentile Amount of outside reading in Minutes/Day:
Percentile Minutes Per Day Words Gained Per Year
90% 40+min/day 2.3 million
50% 13 min/day 6000,000
10% 2 min/day 51,000
THE GAIN FOR JUST READING 40 MINUTES A DAY SHOWS TREMENDOOUS GROWTH!
2. Research based on Facts from Stephen Krashen's The Power of Reading
a. Readers are better writers
b. Reading as a leisure activity is the best predictor of comprehension, vocabulary, and reading speed.
If you haven't read this book, it is well worth your time!
3. Jim Trelease statements from The read-Aloud Handbook
a. Two factors that produced higher achievements: frequency of teachers reading aloud to students and the frequency of SSR/pleasure reading in school.
b. The research overwhelmingly shows that lifetime readers cut their reading eye-teeth on series books and comic books. The more they read the better they do at reading and graduate to more sophisticated books later.
