Have you ever wondered why some teenagers seem to fly through reading assignments while others struggle? The answer may lie not just in what they read, but in how they think about their reading.

In our recent research published in Large-scale Assessments in Education, we examined how specific reading strategies affect reading performance among 15-year-olds worldwide. Using data from over 612,000 students across 79 countries who participated in the 2018 PISA assessment, we found some fascinating patterns that could change how we approach reading instruction.

Not All Reading Strategies Are Created Equal

Our brains process text in complex ways, and becoming aware of these processes—what researchers call "metacognition"—can dramatically improve reading comprehension. But here's the catch: not all metacognitive strategies yield the same benefits.

We found that specific strategies consistently predicted better reading skills and higher achievement scores across different educational settings—from the United States to OECD countries to non-OECD nations.

What Works: The Most Effective Reading Strategies

Our analysis revealed several standout strategies that consistently boosted reading performance:

For understanding and remembering text:

  • Underlining important parts of the text was the top predictor of success across nearly all educational settings
  • Summarizing text in one's own words showed strong positive associations with reading achievement
  • Discussing content with others after reading significantly improved comprehension

Underlining important text sections helps readers identify and remember key information.

For summarizing effectively:

  • Checking that important facts are represented in the summary had the strongest positive impact on reading scores
  • Underlining key sentences and rewriting them in one's own words consistently predicted better summarizing skills

For evaluating credibility of information:

  • Checking the sender's email address when receiving suspicious messages
  • Verifying information through official websites before trusting online content
  • Deleting suspicious emails without clicking links showed positive associations with better assessment skills

What Doesn't Work: Strategies to Reconsider

Equally important, we identified strategies that showed negative associations with reading performance:

  • Focusing only on easy-to-understand parts of text
  • Quickly reading through text twice without deeper engagement
  • Copying sentences verbatim when summarizing
  • Clicking on links in suspicious emails to complete forms

These approaches, while perhaps intuitive to some students, were consistently linked to lower reading scores across educational contexts.

The Connection Between Strategy Use and Reading Achievement

One of our most significant findings was the consistent relationship between metacognitive skills and overall reading achievement. Students who excelled at understanding, summarizing, and evaluating credibility also performed better on reading assessments.

This relationship was remarkably consistent across different educational settings, suggesting that metacognitive strategies have universal relevance despite cultural and educational differences.

What This Means for Students, Parents and Educators

Our research has several practical implications:

For students:

  • Actively engage with text by underlining key points and summarizing in your own words
  • Discuss what you read with others to deepen understanding
  • Develop skepticism about online information by verifying sources

For parents:

  • Encourage your children to talk about what they've read
  • Ask questions that prompt them to summarize information in their own words
  • Model critical evaluation of information, especially online content

For educators:

  • Explicitly teach metacognitive strategies, particularly those with proven benefits
  • Design activities that require students to identify important information and restate it
  • Create opportunities for discussion and collaborative meaning-making
  • Adapt strategy instruction to meet the needs of different students and contexts

A Global Perspective

Interestingly, while our analysis showed some variation in strategy effectiveness across different educational settings, the most powerful strategies remained remarkably consistent. This suggests that certain fundamental approaches to reading transcend cultural and educational differences.

However, we did find nuanced variations that highlight the importance of context-specific approaches alongside universal strategies. Educational systems may benefit from combining broadly effective strategies with targeted approaches that address specific cultural and pedagogical contexts.

Looking Forward

As digital reading environments continue to evolve, metacognitive strategies become increasingly important. The ability to evaluate credibility, for instance, is critical in an era of misinformation and information overload.

Our findings underscore the value of explicitly teaching these strategies to help students navigate increasingly complex reading demands. By focusing on the most effective approaches, we can help more students develop the reading skills necessary for success in education and beyond.

The power of metacognition—thinking about our thinking—may be the key to unlocking reading potential for students worldwide.
