Critical Thinking in English: Analyzing, Arguing, and Debating

 

There’s a peculiar silence that often follows the teacher’s request: “What do you think?” It’s a pause filled not with hesitation, but with a complex tangle of linguistic uncertainty, cultural deference, and the crushing weight of potential grammatical error. For many non-native English speakers, especially those taught in classrooms that favour rote learning over reasoned discussion, the prospect of arguing a point in a second language can feel less like an academic exercise and more like climbing Everest in flip-flops.

Yet critical thinking in English—or in any language—is not merely about speaking up. It is about engaging with ideas, questioning assumptions, and expressing reasoned judgments with clarity and confidence. In the globalised world, where cross-cultural dialogue is the norm and misinformation spreads faster than a rumour in a lift, the ability to think critically and express those thoughts in English has never been more vital.

Let us begin with what critical thinking is not. It is not being critical in the colloquial sense. We are not teaching learners to sneer, scoff, or scold. Rather, critical thinking involves analysis, evaluation, and argument. It requires looking at evidence, drawing conclusions, and—here’s the trick—changing your mind when the facts demand it.

In language classrooms, this can manifest in various forms: evaluating a newspaper article, discussing the ethics of a controversial issue, or debating whether pineapple belongs on pizza (a surprisingly polarising topic, as any teacher will tell you). But at its core, critical thinking is about asking questions: “Is this true?”, “What’s the source?”, “What are the implications?”, “Is there another way to look at this?”

For non-native speakers, the task is doubly challenging. They must not only grasp the content of a discussion but also manoeuvre the nuances of tone, structure, and register. This is not a simple feat. Expressing doubt, for example, requires far more than a shrug. It involves language like “I’m not entirely convinced”, “Have we considered the opposite view?”, or the elegantly non-committal “That’s an interesting perspective, but…”

Debating, too, is a delicate art. The Anglo tradition of debate is, in many ways, gloriously performative. The aim is not merely to win, but to dazzle with rhetoric while maintaining politeness. A well-placed “with respect” can introduce a crushing counterpoint, and phrases like “I’d argue that…” or “Let’s consider another angle” signal disagreement without aggression. These markers help non-native speakers navigate the treacherous waters between confidence and confrontation.

It’s worth noting that critical thinking is also deeply cultural. In some educational systems, questioning a teacher or challenging an idea is frowned upon, even seen as disrespectful. Learners from such backgrounds might struggle with the very premise of critical dialogue. For ELT practitioners, the solution is not to bulldoze these cultural values, but to gradually introduce the idea that questioning is not rebellion—it’s reflection. It’s not an attack, but an invitation.

One effective way to cultivate this is through analysis of everyday language. Advertisements, for instance, are fertile ground. What’s the message behind the slogan? What assumptions does it make? How is it trying to persuade us? A toothpaste ad that claims “nine out of ten dentists recommend it” begs the question—who’s the tenth? And why is no one asking what other products those nine dentists also recommend?

Such exercises reveal that language is never neutral. A political speech, a news headline, a social media post—all of them are constructed to lead us somewhere. To be fluent in English is not merely to understand the words, but to decode the agenda.

And then, of course, there’s the structure of argument itself. English loves a good framework. The classic essay formula—introduction, three body paragraphs, conclusion—is drilled into students from secondary school upwards. While formulaic, it offers a useful skeleton: state your opinion, support it with evidence, acknowledge the other side, and wrap it up with flair.

Phrases like “On the one hand…”, “Nevertheless…”, and “In conclusion…” are the traffic signs of the English essay, helping readers follow the argument even when the terrain gets rocky. For learners, mastering these phrases is empowering. Suddenly, they are not just speaking English—they are thinking in English.

But we should also beware the danger of thinking that structure is everything. Some of the most dazzling thinkers in English write in a style that is meandering, ironic, even contradictory. George Orwell’s clarity, Zadie Smith’s wit, or the late Christopher Hitchens’ barbed eloquence—none of these can be captured by a five-paragraph template. The real art of critical thinking is knowing when to break the rules—and having a good reason for doing so.

In the classroom, this means allowing space for creative disagreement. It means encouraging students to debate whether AI will destroy humanity, or whether Shakespeare is overrated. It means letting them write argumentative essays about mobile phones, social media, climate change, and cats vs dogs. And it means showing them how to back up their opinions with logic, examples, and a healthy dose of scepticism.

For teachers, the role is both guide and provocateur. Ask uncomfortable questions. Challenge lazy thinking. Push your students beyond the safety of memorised phrases. Because true fluency is not just saying the right thing—it’s thinking it.

In the end, critical thinking in English is not just about better essays or exam scores. It’s about agency. It’s about equipping learners to navigate a world of conflicting opinions, dodgy data, and viral nonsense. It’s about helping them find their voice—and knowing how to use it wisely.

So the next time the classroom falls silent after the question, “What do you think?”, don’t rush in to fill the gap. Let the silence stretch, just a little. Give students the space to think. Because from that moment of uncertainty might come the beginning of something powerful: a thought, in English, that is truly their own.
