The teachers we remember, and why they stay with us

Think of a teacher you still remember. The name usually comes first, and then a small moment: how they spoke to you on a bad day, a joke that set off the whole room, the afternoon they sat beside you until something finally made sense. It is rarely a lesson.

That pattern is not just nostalgia. When researchers ask students about the teachers we remember, the same things come up again and again: kindness, help and a laugh, well ahead of subject knowledge. Feelings help those moments stick. And it says something useful about how a class can thank a teacher at the end of the year.

Why do some teachers stay with us for life?

Three kinds of research point the same way:

• What people recall is the relationship. Asked about their best teacher, students mostly describe how that teacher treated them.
• Moments with feeling are stored more strongly. The brain keeps emotional experiences better than ordinary ones.
• It can reach well past school. Feeling cared for by a teacher is linked with how people fare years later.

Each one is below, with what the study found and what it did not.

What do children remember about their teachers?

Most research on teacher-student relationships relies on what teachers report. In 2020, researchers from Macquarie University and QUT asked students instead. Penny Van Bergen, Linda Graham and Naomi Sweller interviewed 96 students in Years 3 to 10, from 19 government schools in Sydney, about the teachers they remembered most. Their paper appeared in School Psychology Review.

What they found:

• Almost everyone had one. Every student in the group without behaviour difficulties could recall at least one teacher they had a strongly positive relationship with.
• It was about what the teacher did. Asked what made that relationship good, 84% described the teacher's behaviour: kindness and care (38%), helpfulness (16%), humour (12%) and effective teaching (10%).
• The teacher came first. Across all the groups, students talked about the teacher's behaviour (57%) more than twice as often as their own (22%).

Good teaching made the list. It just was not at the top. Children remembered being cared for.

What do adults thank their teachers for?

Monash University's Faculty of Education asked the public in a different way. Its #ThankYourTeacher campaign, which began in 2019, invited Australians to thank a teacher on social media, on a campaign website and at two events in Melbourne. The team analysed 328 of those messages and reported the results in October 2020.

This was a public campaign, not a controlled study, so treat it as a snapshot. But it points the same way as the Sydney interviews: what people carry is how a teacher treated them, more than what they taught.

Why do those moments last?

Most of what happens to us fades. In a 2013 review in the Proceedings of the National Academy of Sciences, the neuroscientist James McGaugh summed up decades of research: emotional arousal strengthens the way memories are stored, so we keep, selectively, the experiences that mattered. Stress hormones and a part of the brain called the amygdala help lock them in.

That review was not about teachers. But it may help explain why a small kindness on a frightening day can outlast a whole year of lessons. It arrived at the moment it counted.

Hard moments stick too. In the Sydney study, 41% of students without behaviour difficulties also recalled at least one strongly negative relationship with a teacher. The clashes came down to hostility and injustice: being sworn at, belittled in front of others, or treated differently from the rest of the class.

Does a teacher's care show up later in life?

The best-known evidence comes from university, not school. The 2014 Gallup-Purdue Index surveyed more than 30,000 graduates in the United States. Graduates who recalled a professor who cared about them as a person, one who made them excited about learning, and a mentor who encouraged them to pursue their dreams had more than double the odds of being engaged at work. Only 14% strongly agreed they had all three.

That is an American survey of adults looking back, and it shows a link, not proof of cause. Still, it fits the rest: the teachers who stay with us are the ones who took a personal interest.

What does this mean for a class thank-you?

If kindness, help and humour are what people keep, they are also what a thank-you can name. A voucher thanks a teacher for the year. A specific memory thanks them for the person they were in it.

A few ways to use the research:

• Ask about the person, not the subject. "When was your teacher kind to you?" gets more than "What did you learn?"
• Leave room for all three. Some children will remember a kindness, some the help with reading or maths, some the jokes. The research says all three last.
• Catch the details while they are fresh. Most ordinary details fade, so ask in the last weeks of term, not next year.
• Let children use their own words. The answers in the Sydney study came from what children said, not from a list. A parent can hold the phone while the child talks.
• Make sure it reaches them. In a 2019 Monash survey of more than 2,000 Australian teachers, 71% said they felt underappreciated, even though more than 93% of Australians say teachers do a great job. The gratitude is there. It often stays unsaid.

One way to collect it is a film from the whole class. The class rep sends one link in the parents' group, each child records about a minute at home, and Warmcut puts the messages in order with music and captions, so nobody edits anything. Collecting messages and watching the finished film is free, with a small Warmcut watermark. Pay once, from US$19, to share and download it. Over 10 people? The free film uses the first 10 to record, and paying makes it with everyone.

For timing, the class rep guide has the rule: start four weeks before the last day and send the link two weeks before. For words, what to say in a thank-you message for a teacher has lines for every age, and these teacher appreciation video ideas include questions that get children talking.

What if your child had a hard year with their teacher?

Not every child will have warm memories of this year's teacher, and the Sydney study suggests that is common. A thank-you should never be forced.

• Keep it small and true. One honest line, such as "Thank you for letting me read in the library at lunch", is better than praise the child does not mean.
• Thank someone else as well. The teacher aide, the librarian or the sports coach may be the adult your child remembers from this year. They can get a message too.
• Let them sit it out. Recording should always be optional. A class film is made from whoever records.

For most children, though, there is a teacher this year who will end up among the ones they remember. The last weeks of term are a good time to tell them.
