Your words matter: what not to say in the classroom

In the classroom, avoid teacher-centred “I” language, public judgments about a student, and echoing what students just said. Research shows positive teacher talk measurably raises motivation, engagement and results, while negative talk discourages, so swap “be quiet” for “can you use a softer voice” and praise effort rather than labels.

“Be mindful when it comes to your words. A string of some that don’t mean much to you may stick with someone else for a lifetime,” writes Rachel Wolchin. Nowhere is that truer than between teacher and student, where a sentence tossed off in irritation can pin itself in a child’s mind for years, shaping their mental health for better or worse.

What does the research say about teacher language?

A study of teacher talk found students showed greater interest in completing tasks after exposure to a teacher’s positive language, and that motivation, engagement, behaviour during lessons and attitude towards the subject all rose significantly with it, leading to better results. Teachers and students alike rated positive teacher language as important and negative talk as a source of discouragement. Perhaps the most useful finding: many teachers use negative talk without being aware of it. The problem is rarely malice; it is autopilot.

We have also seen, too many times, harsh classroom words end in drastic steps taken by students. Discipline is necessary; cruelty never is, and the two are separable.

What should teachers avoid saying?

• Teacher-centred language. Heavy use of “I” framing, “I want you to tell me…”, “show me an example…”, turns the classroom into a one-way channel and discourages students from sharing with each other.
• Public judgments. Never pass judgmental statements about a particular student in front of others. Where a student needs addressing, the language of inclusion does the work without the wound.
• Echo talk. Repeating back what a student just said adds nothing; let students expand their own ideas so more gets shared.

What to say instead

The blunt version always has a better sibling:

• “Be quiet” becomes “Can you use a softer voice?”
• “Do you need help?” becomes “I’m here to help if you need me.”
• “Stop crying” becomes “It’s okay to cry.”
• “What a mess!” becomes “It looks like you had fun. Can we clean up now?”

Beyond word choice: control tone and pitch, never use abusive language under any circumstances, and avoid words with a negative connotation. Positive teacher language is also more than words; it includes careful listening and the skilful use of tone, gesture and body language, and it extends to how we speak with families and how we talk about students with colleagues.

Can positive language go too far?

Yes, and the caution is worth hearing. Tim Elmore, founder of Growing Leaders and author of Artificial Maturity, argues that certain kinds of positive talk backfire with young people. Students repeatedly told “you’re special” from a young age can come to feel entitled to special advantages. Students consistently told “you’re smart” can conclude: if I’m so smart, I shouldn’t have to try so hard.

The fix is not less warmth but better aim:

• Instead of “you’re special”: “You’ve got unique gifts that could be very useful when you see the big picture. You can play an essential role on a team.”
• Instead of “you’re smart”: “I love how hard you worked on that problem. That strategy and work ethic will be useful on a job one day.”

Praise the effort and the strategy, not the label. It is the same principle that positive parenting applies at home, and it protects a child’s self-worth instead of inflating and then puncturing it.

A teacher’s sentence costs nothing to say and can be carried by a student for thirty years. Choose the version worth carrying.

Every educator has a personal style, and class dynamics differ; the constant is knowing that words land harder from the front of the room. As the saying goes: once said, they can only be forgiven, not forgotten.
