47 Seconds of Attention: The Invisible Challenge of Teaching in The Age of Screens

If attention spans are shorter, the way lessons are structured becomes crucial. When it comes to teaching English to children, experts agree that there is no single ideal lesson length; instead, it must be tailored to the student’s age and cognitive development.

For young children, aged between 3 and 6, lessons should be brief, lasting between 15 and 20 minutes, as their attention span is limited.  In this age group, it is essential to incorporate dynamic activities such as songs, games or short stories, as well as a wide variety of stimuli to ensure active engagement.

As student’s grow older, their ability to concentrate increases progressively. Between the ages of 7 and 13, lessons can last between 30 and 45 minutes, provided a balance is maintained between explanation and active participation. At these ages, interactive activities such as guided discussions, collaborative exercises, or the use of multimedia resources are essential for sustaining attention.

Teenagers can maintain their concentration during longer sessions, lasting between 45 and 60 minutes, although they still need energy, interaction and changes of pace to prevent them from losing interest..

This approach breaks with the traditional model of long, lecture-style lessons and favours more flexible and dynamic sessions, where student participation becomes the central focus. The key is no longer the length of the lesson, but how the learning time is structured.

Simply shortening the length of lessons is not enough. Teachers agree on one key point: attention is not maintained passively, but is built through interaction.

A survey conducted by Novakid among more than 130 online English teachers highlights that the most effective strategies for maintaining engagement are those that involve active student participation. These include role-play (86.5%), guided conversation (96.3%) and interactive games (96.2%), which, as Rogen García, an English Teacher at Novakid, points out: “are always popular and work well under all conditions, whether it’s online, in a classroom, or regardless of the class size and age of the learners.”

Similarly, the use of visual aids or flashcards also receives a very positive rating – only 4.4% of teachers consider them ineffective. “They keep children interested and engaged during the lesson, grab their attention and make learning feel fun,” says Ali Sullivan, a teacher at Novakid. 

This type of approach puts the learner at the centre of the learning process, encouraging them to participate actively and make decisions. This not only improves concentration but also enhances content retention.

Capturing attention does not mean overwhelming it. One of the biggest challenges of online learning is striking a balance between dynamic, engaging lessons and cognitive overstimulation.

A clear example of this balance is the use of videos in the classroom, a tool widely endorsed by teachers: 89.5% of those surveyed believe that videos are effective for learning English, but that their effectiveness depends on how they are used within the lesson plan. 

When they are well integrated, with a clear pedagogical objective and accompanied by interaction, they become a powerful learning tool. But in a digital environment where children are accustomed to platforms such as TikTok, Instagram Reels or YouTube Shorts — based on endless scrolling and the consumption of ultra-short videos with no engagement — inappropriate use can reinforce patterns of fragmented attention and become a fleeting stimulus. 

The intensive use of audiovisual resources, combined with constant exposure to digital platforms outside the classroom (e.g. TV time, video games, smartphone usage, etc), not only influences the way children pay attention, but also their level of cognitive fatigue. When learning and leisure share the same kind of rapid, visual and continuous stimuli, the brain becomes accustomed to an increasingly fast-paced processing rhythm.

In this context, overexposure to screens can lead to an increasingly common phenomenon: screen fatigue – a form of physical and mental exhaustion that directly affects concentration, motivation and learning retention.

In fact, the World Health Organisation has highlighted the rise in childhood myopia – a common refractive error where close objects appear clearly, but distant objects are blurry – as one of the major public health concerns of the 21st century, with an estimated prevalence of between 30% and 40% of children. Screen fatigue not only affects physical well-being, but also intensifies the difficulty in maintaining attention, thereby reinforcing the initial problem we mentioned at the start of this article: attention span.

At Novakid, we know that the challenge of online teaching is not just technological, but pedagogical. It is not a question of choosing between traditional and digital methods, but of integrating them effectively into the student’s learning process. 

At Novakid, we understand this reality, which is why we offer a model that combines structure, dynamism and real-life communication practice, tailored to the student’s needs in digital environments. Book a free Novakid English lesson now and discover how far your child can go with the right support!
