Why Reading Gaps Keep Widening: The Matthew Effect Explained

Have you ever wondered why some children seem to struggle to catch up in reading with their peers, even with extra support? Why do gaps in reading achievement continue to widen, despite concerted efforts to close them? The “Matthew Effect” in literacy demonstrates why early advantages compound over time and how this phenomenon is widening achievement gaps in reading. Understanding this phenomenon is key to creating equitable educational opportunities.

Understanding the Matthew Effect

The Matthew Effect, named after the biblical verse “the rich get richer and the poor get poorer,” explains how initial advantages in reading can snowball over time. Keith Stanovich’s (1986) research found that early differences in reading skills and vocabulary lead to vastly different outcomes down the line. Look at this graph that represents children with a very small difference in their starting points on literacy skills, and how the gap widens over time:

Why does this gap widen over time? Research shows that children who start with strong reading skills are more likely to enjoy reading and therefore read more. This extra reading exposure accelerates their vocabulary growth and reading proficiency, creating a compounding advantage. Conversely, children who start with lower reading skills often find reading frustrating and avoid it, leading to fewer opportunities for growth and a widening gap.

Not all skills emerge in this way. Compare the Matthew Effect with the “Catch Up Effect” graph below that illustrates the development of walking in children:

Unlike learning to walk, which is a skill that most children develop naturally given basic support, reading depends on experience. This means that the quality and quantity of a child’s experiences with books and reading instruction make a huge difference. Inequities in access to rich literacy experiences early in life can lead to significant disparities in reading outcomes.

My insights: The Potential of Personalization

The compounding nature of early reading skills suggests that interventions must be both timely and personalized. We can’t afford to wait for struggling readers to “catch up” on their own because reading is not a skill that automatically evens out over time. Personalization—support tailored to an individual’s needs—has the potential to mitigate these effects and close achievement gaps.

What the Matthew Effect demonstrates is that human development is anything but average, and even small individual differences can have lasting long-term impacts in some domains of development (like reading) and not others (like walking).

This is one reason why there is so much excitement in the learning community about the potential of AI to personalize reading instruction. Imagine targeted, high-quality reading opportunities provided early and consistently, tailored to each child. The personalization buzzword becomes more meaningful when we consider its real potential: closing achievement gaps and ensuring that all children have an equal shot at fulfilling their potential.

Key Takeaways

1. Address Early Disparities: Focus on early interventions that give children with fewer literacy experiences a boost. The earlier we intervene, the greater impact we can have on a child’s reading trajectory.

2. Embrace Personalization: Tailor reading instruction to meet the diverse needs of learners, using strategies that recognize and address the multifaceted nature of reading skills.

Matthew Effect: A phenomenon in which early advantage or success leads to later success in learning. (HPL, Unit 3.1.2)

Catch-Up Effect: A phenomenon in which learners attain similar levels of performance in a domain despite early differences in starting points in that domain. (HPL, Unit 3.1.2)

Personalization: Tailoring support and educational practices to meet the unique needs of each learner. Personalization aims to mitigate differences in starting points and promote equitable growth by adapting resources and teaching methods to help each individual achieve their full potential.
