From Wikipedia:
In education the term Matthew effect has been adopted by Keith Stanovich from sociology, a psychologist who has done extensive research on reading and language disabilities. Stanovich used the term to describe a phenomenon that has been observed in research on how new readers acquire the skills to read: early success in acquiring reading skills usually leads to later successes in reading as the learner grows, while failing to learn to read before the third or fourth year of schooling may be indicative of life-long problems in learning new skills. This is because children who fall behind in reading, read less, increasing the gap between them and their peers. Later, when students need to "read to learn" (where before they were learning to read) their reading difficulty creates difficulty in most other subjects. In this way they fall further and further behind in school, dropping out at a much higher rate than their peers.
In the words of Keith Stanovich (Adams, 1990, pp. 59–60):[1]
Slow reading acquisition has cognitive, behavioral, and motivational consequences that slow the development of other cognitive skills and inhibit performance on many academic tasks. In short, as reading develops, other cognitive processes linked to it track the level of reading skill. Knowledge bases that are in reciprocal relationships with reading are also inhibited from further development. The longer this developmental sequence is allowed to continue, the more generalized the deficits will become, seeping into more and more areas of cognition and behavior. Or to put it more simply -- and sadly -- in the words of a tearful nine-year-old, already falling frustratingly behind his peers in reading progress, "Reading affects everything you do"
We have a crisis on our hands.
Of the fourth-graders who took the National Assessment of Educational Progress (NAEP) reading test in 2009, 83% of children from low-income families—and 85% of low-income students who attend high-poverty schools—failed to reach the “proficient” level in reading.
How does this factor into the "boy problem"?
From elementary through high school, males are reading at lower levels than females.
