Do reading apps help?

A positive average that hides big differences

The short answer

Do reading apps and computer programs help young children learn to read?

An analysis of 36 studies of educational apps for preschool to grade 3 found a positive average effect on achievement, and says the average hides large differences from app to app. The authors say there is surprisingly little cause-and-effect evidence on whether educational apps work.

What the research found

  • 6 × Reported by a research review
  1. A meta-analysis of 36 studies of educational apps for preschool to grade 3 found a positive average effect on achievement, about the same in math and in literacy.

    In the source’s own words“results from rigorous experimental and quasi-experimental studies yielded a mean weighted effect size of +0.31 standard deviations on overall achievement and comparable effects in both math and literacy.”
    Reported by a research reviewSource 1, Abstract, p. 1
  2. The same meta-analysis says the average hides large differences from app to app.

    In the source’s own words“the positive overall effect masks substantial variability in app effectiveness”
    Reported by a research reviewSource 1, Abstract, p. 1
  3. Effects were larger for preschoolers than for K-3 children, larger on tests made by the researchers than on standard tests, and larger for narrow skills than for broad ones.

    In the source’s own words“Treatment effects were larger for studies involving preschool rather than K–3 students, for studies using researcher-developed rather than standardized outcomes, and for studies measuring constrained rather than unconstrained skills.”
    Reported by a research reviewSource 1, Abstract, p. 1
  4. The authors say there is surprisingly little cause-and-effect evidence on whether educational apps work.

    In the source’s own words“there is surprisingly little causal evidence about their effectiveness or the features that enhance or diminish their effectiveness.”
    Reported by a research reviewSource 1, Introduction, p. 2
  5. A review of programs for struggling readers in grades K-5 concluded that computer-assisted instruction generally had few effects on reading.

    In the source’s own words“Computer-assisted instruction generally had few effects on reading.”
    Reported by a research reviewSource 2, Abstract, p. 3
  6. For one narrow skill, awareness of the sounds in words, the National Reading Panel concluded that computers were effective and the gain carried over to reading.

    In the source’s own words“the Panel concludes that computers are effective for teaching PA and for promoting transfer to reading, but they may be ineffective for teaching spelling to disabled readers.”

What this means at home

  • An app can help, but apps differ a lot. An average says little about one app.
  • Effects were larger for narrow skills than for broad ones.
  • Treat an app as practice beside your teaching, not as the teaching.
  • The free two-minute check shows what your child needs to practice.

What the research does not tell us

  • The apps meta-analysis says there is little research done at large scale, which limits how far its findings can be applied.
  • The studies controlled how long children used an app, so they may not show how the amount of real-life use relates to results.
  • In 2000 the National Reading Panel found too few studies of computer technology in reading teaching to combine them.
  • The Slavin review is about school programs for struggling readers studied up to 2009, so it does not cover today's tablet and phone apps.

How we write these pages

  1. We read the source itself, not a news story about it.
  2. Every finding on a page names its source and where in the source it is found, so you can check it.
  3. We say how strong the evidence is, in the words of the people who reviewed it.
  4. We say what the research does not tell us. Most studies are done in schools, and no study can say what one child needs.
  5. If we get something wrong, tell us at hello@sounditoutreading.com and we will correct the page.
