The power of reading: books, vocabulary and learning

The power of reading: books, vocabulary and learning

Did you know that 2026 is the UK’s National Year of Reading? This long-overdue initiative reflects growing concern and renewed commitment around children’s reading and literacy.

As Dr Maria Korochkina, our latest Researcher of the Month, puts it: “The ability to read opens up worlds. Reading enables children to progress into post-primary education and provides the basis for lifelong learning and prosperity into adulthood”.

Frequent readers tend to have a stronger understanding of both their own and others’ emotions. They are often better able to communicate these emotions, a skill linked to higher emotional intelligence and improved mental wellbeing. Reading also encourages cause-and-effect reasoning and helps children imagine scenarios beyond the immediate moment - developing the skill of -future-thinking'. A rich vocabulary underpins learning across the school curriculum, strengthens thinking and communication skills, and predicts both academic attainment and later life outcomes. Research consistently shows that the most effective way to build vocabulary is through reading.

However, learning to read well is not quick or effortless. The journey to skilled reading typically spans around ten years, requiring high-quality classroom instruction alongside sustained practice through independent reading. For many children, this process is painstaking, demanding consistent teaching, encouragement and opportunity over time.

Against this backdrop, recent evidence presents a worrying picture. Fewer children are reading for pleasure than ever before. In 2024, only one in three UK children and young people aged eight to 18 reported enjoying reading in their free time. Even more strikingly, just one in five said they read daily for pleasure, the lowest level recorded since the National Literacy Trust began collecting this data in 2005.

This matters because reading ability and reading enjoyment are deeply intertwined. Children who find reading effortful are far less likely to choose to read independently. Dr Korochkina’s research highlights how early reading experiences shape later habits: difficulties with phonic and morphological knowledge in the early stages of reading acquisition can have a snowball effect, reducing confidence, fluency and motivation over time.

Her work also offers a powerful note of optimism. Books that children actively choose to read, including contemporary, popular texts, provide rich opportunities to develop vocabulary, particularly when children read widely. Ensuring access to a diverse range of engaging reading material, alongside strong early instruction, can play a vital role in building both reading skill and reading motivation.

Fostering confident, motivated readers requires long-term commitment. It is not enough for children simply to have books available to them. They need skilled teaching, time, practice and a culture that values reading as both a skill and a pleasure.

Summary

Reading and vocabulary growth

Dr Korochkina has developed an incredible database called CYP-LEX - The Children and Young People’s Books Lexicon which is freely available online for anyone to explore (the research findings are available here). This unique database captures every single word used in 1,200 books that are popular with children and young people in the UK, offering an unprecedented window into the language children and young people encounter through reading. CYP-LEX contains data on over 100,000 distinct words drawn from books written for children aged 7 to 16, with 400 books analysed for each age band (7–9, 10–12 and 13–16). By mapping how vocabulary is used across different texts and age groups, the database provides powerful insights into the richness, range and progression of language in children’s literature.

The findings highlight just how vast the vocabulary in children’s books really is. Across the 1,200 books analysed, Dr Korochkina identified more than 100,000 different words, including nuanced emotional language that rarely appears in everyday speech. She found that even books written for younger readers introduce vocabulary that broadens understanding of the world and quietly builds the foundations of flexible, future-focused thinking.

Obviously, it would be impossible for a child to memorise this many printed words. This is why phonics is so important. Understanding how letters and sounds work together allows children to decode unfamiliar words independently, rather than relying on memory alone. Without this knowledge, the sheer range of words children encounter when reading can quickly become overwhelming.

Dr Korochkina’s research also shows that children’s books expose young readers to a far wider range of vocabulary than many other forms of media. Around 40% of the words found in children’s books do not appear in BBC television programmes aimed at children of the same age. Strikingly, around one in five words used in books written for young people aged 13–16 are not encountered on BBC television channels targeting adult audiences. The vast majority of words in children’s books are only encountered a few times and children will come across new words in every book they read.

This makes books a uniquely powerful tool for expanding children’s vocabulary. At the same time, it highlights an important challenge. For many children, reading can feel difficult from the very start of independent reading, as they are confronted with large numbers of unfamiliar words. Strong foundational reading skills and sustained support are key to help children persist and succeed as readers. It is crucial to develop reading skills and motivation early on. And because different books use different words, it is important that children read widely.

Building blocks of language

Books are a far richer source of morpheme (a morpheme is the smallest unit of meaning in a word) exposure than everyday spoken language. Strong morpheme knowledge not only helps children decode and understand words efficiently, but also supports broader language skills, including vocabulary, comprehension and communication. Because explicit instruction in morphology is often limited in schools, reading can become the main way children internalise morphemes. Regular exposure to print through a wide range of books is therefore essential for developing morpheme knowledge, boosting reading fluency and enhancing overall language ability.

Motivation to read

Reading skills and reading motivation reinforce each other in a virtuous cycle. Children with strong reading skills can read more fluently, which in turn makes the experience enjoyable. This enjoyment encourages more reading, leading to greater learning and academic success. When reading is supported and nurtured, it builds confidence and lays the foundations for lifelong learning.

Implications

What can parents and educators do?

Share reading. This is vital in the early years. When children are young, explore picture books together. These too contain rich vocabulary. Children’s attention to print will increase with age, particularly if you point to the words. If your child lacks motivation, perhaps agree to take turns reading to each other, and discuss the text and images.

Try not to worry about time. Even five minutes of reading each day exposes children to language and ideas, and can create great reading habits. Some children may struggle to concentrate for longer. If you are really time-poor, can you read with them over video call or record a story for them to listen to? Could you buy them a book that you both read independently and then discuss together? Can you plan ahead and schedule in some time to make it a non-negotiable?

Don’t underestimate the power of modelling. Think about your own reading habits. Could you organise 15 minutes of family reading time each evening?

Talk about interesting words. Explore their meanings. Delve into their construction. Be curious and interested.

Provide children with choice and freedom. Use your local library and bookshops. Bring them to spaces and places where they interact with books. Pressure won’t help to boost motivation - gentle nudges are more effective.

Lean into their interests. Don’t be too prescriptive and avoid criticising their choices. Target their enjoyment. Children who read for pleasure are likely to do significantly better at school than peers who don’t. Even popular books, not selected for literary merit, are packed with learning opportunities. Motivate struggling readers through careful text selection. Consider graphic novels or books with lots of images alongside text. You might encourage them to ask slightly older children what they enjoyed reading at their age.

Make connections between texts and real life experiences. Relate what you read to things that have happened or are happening in your own lives. It can be empowering to notice how book characters cope with things similar to something going on in your own life or in your child’s.

Make use of existing resources. BookTok can be interesting and empowering for teens. Research shows that it has been highly motivating for many young people. Book Trust’s Bookfinder and Oxford Owl both provide great recommendations. Tooled Up subscribers can browse through our monthly picks of new releases. Here's January's to get you started.

Remember that the route to skilled reading is the same for all children. If your child struggles with reading or has a dyslexia diagnosis, the route to skilled reading remains the same - they just might need more support or tailored activities. All children need phonics learning and practice.

Make use of immersive reading tools and assistive technologies. This might be listening to an audiobook whilst also reading it. This can boost understanding and help with the development of decoding.

    Crossing the line into cybercrime

    Crossing the line into cybercrime

    As the most digitally connected generation so far, young people today face new challenges. Our latest Researchers of the Month, Professor Davidson and Dr Farr, have found that in the last decade, an increasing number of young people (particularly young men) have committed serious cybercrime offences, particularly hacking and money laundering. Their new book, written following a large research project funded by the European Union’s Horizon 2020 research and innovation programme, seeks to understand the drivers behind this trend. It explores a range of potential factors that may lead young people to engage in risky online behaviours, and to identify effective pathways for prevention.

    Supporting Children’s Use of AI

    Supporting Children’s Use of AI

    Children and young people are now growing up surrounded by AI, and the landscape is shifting fast. In the UK, recent data from Ofcom and Internet Matters suggests that around half of children aged 8–17 regularly use generative AI tools such as ChatGPT, Bard or Snapchat’s MyAI. Many describe these interactions as feeling like conversations with a friend. A recent report from Common Sense Media found that 33% of teens had actually chosen to talk to an AI companion instead of a real person about something important or serious. Whether children are asking voice assistants to answer their questions, relying on chatbots for bedtime stories, using learning apps for revision or engaging with large generative AI models, it’s essential to remember that most of these systems were built with adults in mind, not children. They often assume levels of attention, memory and emotional maturity that younger users simply don’t have. Even older children and teenagers, who increasingly use AI as a supportive confidante (often without adult supervision or knowledge), are still learning to navigate boundaries around trust, identity and emotion. Our latest Researcher of the Month, Dr Nomisha Kurian, wants this to change. She has developed a new framework called Developmentally Aligned Design (DAD), which outlines how AI can be built with children’s needs, vulnerabilities and strengths at its core. She also chatted to us at Tooled Up, sharing practical tips on recognising when children may be relying too heavily on AI for emotional connection, how to talk to them about healthy boundaries, and how parents and educators can help children and young people use AI tools safely, creatively and critically.

    Algorithmised Girlhood: Teenage Girls and TikTok

    As part of the early stages of her PhD study, our latest researcher of the month, Chiara Fehr, ran several focus groups about experiences of TikTok with eight 17 year old girls. Using creative methods, such as ‘TikTok show and tells’ a collaging session and a utopic mapping exercise, Chiara is exploring whether dominant narratives around growing up in a digitised world reflect the real life experiences of teens, and has summarised her findings so far in a recent article.

    “[They use devices] alllllllll day long”. What do children think about our tech use?

    We're all used to reading about children and young people's increasing use of digital tech. But what about adults' use? And what impact might our tech use have on family life? Parents today are spending an unprecedented amount of time on their devices. One study found that parents spend an average of nine hours per day engaged with screen devices. Over four hours of this is on smartphones, averaging 67 phone checks per day. Despite children's central role in family life, their voices and perspectives on the device use of the adults around them have been largely neglected in research. Along with colleagues, our latest Researcher of the Month, Professor Cara Swit, has published a fascinating study exploring the experiences and perceptions of children aged six to nine about their parents’ device use at home and its impact on them.

    Students’ views on smartphone bans

    Students’ views on smartphone bans

    In recent years, banning or restricting children’s access to smartphones and social media has grasped the attention of policy makers, schools and parents. A number of countries, including France, Turkey, Norway, Sweden, and regions of the US and Canada have introduced laws, policies or guidance for schools to ‘ban’ or heavily restrict the use of phones. Within Ireland, in 2024, the Minister for Education announced her intention to introduce smartphone bans in post-primary schools, whilst at the same time acknowledging that individual schools are best placed to decide on the scope and scale of restrictions for their students. Whilst these bans aim to protect children from harm, and teachers often anecdotally report seeing benefits, evaluations of existing research highlight a lack of evidence on their efficacy. At the moment, we simply don't know enough about the impact of bans. Evidence is hampered by the fact that technological developments and technology use is moving at a faster pace than research. Some studies suggest that bans are beneficial to academic outcomes and mental wellbeing. Others suggest no effects. However, many studies have methodological weaknesses, use small samples or retrospective data, and can't ascribe causal mechanisms. Our latest Researcher of the Month, Dr Megan Reynolds, has recently published a paper which explores young people's perspectives and experiences of smartphone bans in their schools. Unlike most previous research, it centres student voices in this high profile issue.

    Do teens with mental health conditions use social media differently than their peers?

    Do teens with mental health conditions use social media differently than their peers?

    As Luisa Fassi, our new Researcher of the Month, comments, "The link between social media use and youth mental health is hotly debated, but hardly any studies look at young people already struggling with clinical-level mental health symptoms". In fact, Luisa's large systematic review and meta-analysis found that only 11% of papers published on the topic since 2007 focused on young people with clinical conditions. Her review also showed that the data used to evidence mental health conditions in these existing studies is not always strong or especially robust. Many report links between social media and mental health on the basis of short self-report questionnaires, where young people are asked about symptoms. Whilst this wasn't found as part of Luisa's review, it is also the case that very few papers in the field differentiate between different mental health conditions, or examine different symptoms or conditions (such as anxiety, ADHD or eating disorders) in isolation. To address this research gap, Luisa and colleagues have recently published a fascinating and nuanced paper. It analyses both quantitative and qualitative dimensions of social media use from a nationally representative survey of 3,340 teens in the UK aged between 11 and 19 years old, which was conducted by NHS Digital in 2017. Rather than gathering mental health data from self-report questionnaires, the young people in the survey underwent a full clinical screening, which included interviews with the young people, their parents and teachers. Information about social media use came from questionnaires completed by participants. They were not asked about specific platforms. Luisa used this data to gather novel insights into how social media and mental health are related in teens who both meet and do not meet diagnostic criteria for a wide range of mental health conditions. The study does not establish any causal links, but it does reveals a range of differences between young people with and without mental health conditions when it comes to social media.

    Navigating the feed: younger adolescents' reflections on algorithmically curated social media

    Navigating the feed: younger adolescents' reflections on algorithmically curated social media

    Our latest researcher of the month, Roxana Pomplun, has investigated the interactions, experiences and perceptions of younger adolescents, aged 11, 12, and 13, with algorithmically curated platforms such as TikTok, YouTube Shorts, Spotlight on Snapchat and Reels on Instagram. These kinds of platforms use algorithms to personalise and tailor feeds, harnessing user data to suggest content that the individual is most likely to be interested in and engage with. As such, young people have little control over what they are seeing in their feeds. Tech companies are not yet required to be transparent about the data that they are collecting, but it tends to include demographic information such as age, gender or location, along with use patterns. Whilst these sites dominate the digital lives of tweens and teens, until now they have received little dedicated research attention, particularly in relation to younger users, with most existing studies focusing on older teens. Whilst we know that most social media platforms have age limits of 13, we also know that many younger children are active users, particularly of algorithmically curated platforms like TikTok and YouTube Shorts. Given that early adolescence is a life phase marked by critical neurological development, identity development and heightened susceptibility to mental health issues, deepening our understanding of how younger adolescents engage with social media is vital. Roxana's qualitative research, where a group of young people eloquently explore their own experiences and perceptions, broadens our knowledge of social media use within an age group that appears increasingly aware of the digital influences shaping their online experiences, yet which is still in need of support to fully navigate these ecosystems.

    Looking beyond smartphone bans

    Looking beyond smartphone bans

    Over the last year or so, there has been a surge in public concern around smartphones and social media. Banning or restricting children’s access to smartphones and social media has grasped the attention of policy makers, schools and parents. A number of countries, including France, Turkey, Norway, Sweden, and regions of the US and Canada have introduced laws, policies or guidance for schools to ‘ban’ or heavily restrict the use of phones. In the UK, there are proposals to raise the age of ‘internet adulthood’ from 13 to 16, and to ban smartphones in schools. The third reading of a private members’ bill on this topic will be heard in parliament in July. Whilst these bans aim to protect children from harm, recent studies highlight a lack of evidence on their efficacy. Along with a team of international experts, our latest Researcher of the Month, Professor Victoria Goodyear, argues that, in isolation, banning smartphone and social media access fails to equip children for healthy use of technology. She suggests that there is a need to shift debates, policies and practices away from a sole focus on restricting smartphone and social media access, toward an emphasis on nurturing children’s digital skills for healthy technology use, and a rights-respecting approach which is underpinned by age-appropriate design and education.

    Encouraging adventurous play in the preschool years

    Encouraging adventurous play in the preschool years

    Tune into our podcast interview with April's researchers of the month here. As well as providing numerous opportunities for exploration, joy, and expression, outdoor and adventurous play - the type of play that allows children to take age-appropriate risks - is associated with a range of positive health behaviours and outcomes. Yes, we're talking about the kind of play that might leave us adults with our hearts in our mouths at times, as children start to disappear up a tree, or engage in a rough and tumble game of chase. But its benefits are wide-ranging and known impacts include increased levels of habitual physical activity alongside better mental health and positive mood. In 2019, Dr Hesketh was involved in the creation of physical activity guidelines in the UK, which explicitly note the importance of outdoor play for children in the preschool age group. We know quite a lot about the play habits of school-aged children, but until now, have had significantly less data on their younger counterparts. Our Researchers of the Month, Dr Kathryn Hesketh and Professor Helen Dodd set out to discover how much time preschool-aged children spend playing in a range of indoor and outdoor spaces, and how adventurously they are playing within them. In the first national survey of play in children of this age, they asked over 1000 parents of two to four year olds about their children’s play habits, finding that, on average, children aged two to four spend around four hours per day (outside of educational settings) playing. Just under 50% of this was spent playing outdoors. Their findings shed interesting light on some inequalities in play, even in the youngest age group, which may exacerbate existing inequalities in health.

    Fostering a school culture against bullying: the KiVa Programme

    Fostering a school culture against bullying: the KiVa Programme

    Bullying is an extremely important public mental health risk. Around one in five primary school children report being bullied at least weekly. Children who are bullied are more likely to experience depression and anxiety, and are at heightened risk of mental health issues in adolescence and adulthood. Whilst schools in England and Wales are required to have anti-bullying policies, rates of bullying remain high. Bullying is preventable, but schools need more help to tackle it. Typically, school policies focus on how to handle bullying once it happens. However, evidence suggests that a comprehensive approach involving the entire school to prevent bullying, alongside clear strategies for addressing confirmed cases, is the most effective way to tackle the issue. KiVa is one such whole-school approach, developed in Finland by Professor Christina Samivalli. A large study in Finland which involved 28,000 primary school pupils found that adopting the KiVa programme in Finnish schools significantly reduced bullying and improved children's mental wellbeing. The programme has since been rolled out nationally by the Finnish government and ongoing use of KiVa in Finnish schools is associated with year-on-year incremental reductions in bullying. Along with colleagues, our researcher of the month, Professor Judy Hutchings OBE, has tested the effectiveness of the KiVa Programme in UK primary schools. The study involved over 11,000 children in Wales, Birmingham, Oxfordshire and Devon, and showed a 13% reduction in reported rates of bullying when compared with existing school approaches to tackle bullying.
