Three Hours a Week Isn't Enough: Why students need more English outside the classroom

How much time do your students spend reading or listening to English outside their lessons?

For most students, the honest answer is probably: not much. A few hours of English lessons, a little homework and then... very little contact with the language until the following week.

As teachers, we spend a huge amount of time planning engaging lessons, explaining grammar and creating opportunities for communication in class. And all of that matters. But our contact time with students is limited. If language acquisition depends on meaningful exposure to English, then what happens outside the classroom matters just as much as what happens inside it.

So I find myself asking: Are we doing enough to help our students continue developing their English beyond lesson time?

Over the past few weeks, while studying Second Language Acquisition (SLA) theory as part of my Delta Module 1 course from Take Your Time Delta led by my tutor Sandy Millin, one idea has continued to come back to me: while we can't personally provide all the English input our students need, we can encourage them to find more opportunities to engage with the language.

We often encourage our students to "practise English" outside class, but what does that actually mean? Watching Netflix? Reading a graded reader? Completing additional grammar exercises? These activities aren't all supporting language development in the same way. Understanding the difference between explicit learning and implicit learning, and the role extensive input plays in language acquisition, can help us give learners much more effective advice about how to spend their time outside the classroom.

What is implicit learning?

Second Language Acquisition (SLA) researchers often distinguish between explicit and implicit learning:

Explicit learning is conscious. It's what we often associate with the classroom: studying grammar rules, memorising vocabulary or completing controlled practice activities.

Implicit learning, on the other hand, is when learners pick up patterns in the language without consciously noticing or analysing them. It tends to happen incidentally - as a natural byproduct of reading or listening for meaning, rather than it being the goal of the activity.

This distinction is important because, while explicit knowledge can help learners understand how the language works, most SLA researchers agree that it's implicit knowledge that plays the biggest role in fluent, automatic communication. There's debate about exactly how the two connect - Krashen, for example, argues that explicit and implicit knowledge are entirely separate systems, and that conscious learning can never turn into acquired competence. Other researchers take a softer view, seeing explicit knowledge as something that can support or guide acquisition, even if it doesn't directly become it. For teachers, the practical takeaway is similar either way: explanation alone isn't enough - learners also need extensive, meaningful engagement with the language.

How does implicit learning happen?

One of the most influential answers to that question comes from Krashen's Input Hypothesis. Krashen argues that we acquire language through comprehensible input: language that we can mostly understand, even if it contains a few new words or structures. He described this as i + 1 - meaning input that is just beyond the learner's current level.

The key idea is that during acquisition, learners' primary focus is on meaning rather than consciously analysing grammar. As long as they can understand the message, their brains gradually begin to notice and acquire new language naturally.

Although aspects of Krashen's theory have been debated over the years, his emphasis on rich, comprehensible input continues to influence language teaching today.

And this isn't just theory for me - it matches my own experience of learning Spanish. When I moved to Spain 15 years ago, I spoke no Spanish - nada. Of course, I had some classes along the way, bought grammar and vocabulary books, tried my hand at the app with the green owl - and all of those things helped, to some degree. But really, that's not where most of my learning happened.

My Spanish came from living my life in the language: listening to conversations around me, reading signs and menus, watching television, attending appointments, chatting with housemates and friends... and doing this day after day. I wasn't consciously trying to memorise grammar rules; I was simply trying to understand and communicate. Over time, my comprehension improved, my communication became more fluent and without always being able to explain why, I knew what sounded right. I'm sure we've all had students justify their answers with this reason ("It just sounds good") - it's not a poor explanation, it can actually be a sign that implicit language knowledge is developing.

It's my own experience that truly convinces me of the power of extensive input and implicit learning. It wasn't one conversation or visit to the pharmacy that made the difference - it was the cumulative effect of thousands of small encounters with Spanish over time. I'm fully aware that as teachers (particularly those of us working in non-English speaking countries), we can't feasibly recreate this kind of immersion for our students, but we can help them build more opportunities to experience English beyond the classroom in order to maximise their exposure to and engagement with the language.

Isn't understanding grammar rules enough?

For the communicative goals most of our learners have? No. This is where VanPatten's Input Processing Theory adds another piece to the puzzle. VanPatten argues that learners process language for meaning before form. In other words,  when working out what a sentence means, learners will grab onto whatever gives them meaning fastest (a word like "yesterday") and often skip past grammatical markers that carry the same information ( like the "-ed" ending). It's one reason why explaining a rule doesn't automatically mean learners will notice or use it next time they encounter it.

This is probably something many teachers have experienced: we can spend twenty minutes explaining a grammar point, have students complete the practice exercises successfully, and then... they can't use it accurately in conversation days later. This doesn't necessarily mean the lesson failed or the students forgot what they learnt. It simply means that understanding a rule isn't the same as acquiring it - knowing about a pattern and being able to use it automatically, in real time, are two different skills.

Learners need repeated encounters with language in authentic, communicative contexts before grammatical patterns become more readily available to use. Explicit instruction has an important role to play, but explanation alone rarely leads to fluent language use (unfortunately) - and neither does a single podcast episode or one conversation. It's repetition that turns understanding into automatisation.

So where do these repeated encounters come from?

If learners need this kind of repeated exposure before language becomes automatic, we need to consider how they can get enough opportunities to encounter it.

The answer isn't usually another grammar worksheet.

It's through extensive input - engaging with large amounts of English through reading, listening and watching, where the focus is on understanding and enjoyment rather than studying the language itself. Every encounter gives learners another opportunity to notice vocabulary, collocations and grammatical patterns in context, building the kind of implicit knowledge that supports comprehension and fluent communication.

What does this mean for us as English teachers?

As teachers, we can't realistically recreate full language immersion for our learners, and we can't control what our students do once they leave the classroom. What we can do is help them make better choices about the English they engage with outside our classes.

Rather than simply encouraging students to "practise English", we can guide them towards activities that provide regular, enjoyable and comprehensible input. Our role becomes less about being the main source of input and more about helping learners identify opportunities to engage with English regularly.

One thing's worth remembering, though: learners tend to choose material that's far too difficult because they think that's how they'll make the fastest progress. But, as Krashen's i + 1 Input Hypothesis reminds us, learners make progress when they encounter language that's just beyond their current level - challenging enough to stretch them, but still accessible enough to understand.

Vygotsky's concept of the Zone of Proximal Development provides us with another useful reminder: learners can often go further with the right support than they could on their own. As teachers, we need to make sure therefore, that we recommend input at the right level of challenge but also with sufficient scaffolding and support.

Practical ways to increase extensive input outside the classroom

Understanding the theory is one thing, but how can we actually help our students build these habits?

The good news is that promoting extensive input doesn't mean setting more homework (hurrah!). In fact, the most effective forms of input often come from activities our most successful learners are already choosing to do themselves because they genuinely enjoy them.

Here are some ideas I would recommend to my own students:

📖 1 Encourage extensive reading

Students often assume they should read complete novels in order to improve their English. In reality, if they're stopping every few lines to check a dictionary, they're no longer reading extensively, they're studying intensively. Instead, encourage learners to choose material they can understand comfortably, such as:

• graded readers

• children's books or young adult fiction

• comics and graphic novels

• simplified news websites

• blogs about topics they already enjoy

🎧 2 Make listening part of everyday life

Listening doesn't have to happen during dedicated study sessions. Encourage students to build English into routines they already have. For example:

• podcasts while commuting

• YouTube while cooking

• an episode of their favourite series in English

• music while reading/singing the lyrics

• audiobooks while walking the dog

🎮 3 Let hobbies do the work

One of the easiest ways to increase input is for students to stop separating English from their everyday life. Instead of telling students to "study English", encourage them to do what they already enjoy, but in English. Whether it's football, gaming, crochet, fitness, Formula 1 or make-up tutorials, there's an endless amount of content available in English. Story-driven games, multiplayer games and online communities can provide particularly rich input through dialogue, instructions and interaction. When students are genuinely interested in the topic, they're much more likely to stick with it.

🤳🏻 4 Curate social media

Probably one of the easiest changes. Most of our students spend significant time online already, so why not make their digital spaces work for them? Encourage them to follow English-speaking creators, educators or influencers related to topics they already enjoy. The more they interact with English online, the more likely it is that similar content will start to appear on their feeds.

🗣️ 5 Create opportunities for real interaction

I've mostly focused on input, but meaningful interaction matters too. Your students don't necessarily need a regular language exchange partner. They could:

• join an online community centred around a hobby

• leave comments on YouTube videos

• participate in gaming communities

• ask questions on Reddit

• attend local language exchanges

My reflections

I think we often underestimate just how much of language acquisition happens quietly, outside our lessons, without a worksheet in sight. As teachers, we can't control what happens once our students leave the classroom - but we can plant the seed, model the habit, and keep checking in. A five-minute conversation at the start of a lesson ("What have you watched/read/listened to in English this week?") reminds students that this matters, and keeps them accountable in a low-pressure way.

It's not about replacing what we do in class (fortunately!) - explicit instruction, corrective feedback and practice do matter. But if acquisition depends on meaningful input, opportunities to process language for meaning, and the right level of challenge, then helping students find more English they genuinely enjoy engaging with might be one of the most impactful things we do as teachers.

What's one type of input you could suggest to your students this week?
