This skill develops by using the language in real exchange of ideas — through plenty of regular speaking practice. Creating discussion opportunities where the teen can defend their view, disagree, and give reasons, and giving them set phrases (I agree/disagree, I think, because), is the most effective way. As production increases, both fluency and the ability to structure thought strengthen.
Detailed Explanation
Expressing ideas fluently and discussing is one of the highest-order speaking skills, because it requires both producing language quickly and structuring thought on the spot. The good news: this skill develops strongly with the right practice.
No fluency without production
Applied linguist Merrill Swain's "output" approach emphasizes that using language fluently develops only by producing it plentifully. Discussion is the richest form of this production: when a teen defends an idea, disagrees, or gives reasons, they use the language actively and creatively. So creating real exchange-of-ideas opportunities for the teen is the most effective way to develop fluency.
Building blocks: set phrases and thinking time
Discussion skill speeds up when the teen is given certain "building blocks": expressing opinions ("I think...", "in my view..."), agreeing/disagreeing ("I completely agree", "I'm not so sure"), justifying ("because...", "for example..."), and offering a counter-view. These patterns make it easier for the teen to organize their thought. Also, giving the teen time to form their idea and having them discuss topics that genuinely interest them increases participation and fluency.
To develop discussion skill
- Create real exchange-of-ideas opportunities; choose topics the teen is interested in.
- Teach opinion and justification phrases; these organize thought.
- Give the teen time to form their idea; fluency comes with ease, not pressure.
- Model offering counter-views and disagreeing politely; discussion needs many angles.
- Don't correct every mistake while speaking; flow feeds on courage.
Points to keep in mind
Reducing discussion skill to grammatical accuracy alone is misleading; what matters most here is conveying the idea fluently and persuasively. Likewise, imposing discussion on topics the teen isn't interested in or that are too abstract lowers participation. The real goal is for the teen to express their own ideas confidently and fluently; that comes through meaningful topics and plenty of practice.
Expert Note — Andrea Massari Rosario
With teens I work on discussion with, I first give a few magic phrases: "I think", "because", "I agree but...". These small building blocks let the teen present their idea far more organized at once. Then, if I get them talking about something they truly care about, fluency comes on its own. Because when defending something they care about, a person forgets the language and focuses on the idea.
