Interest-Led Learning: Using the Obsession as the Doorway

My child only cares about one thing

Some children want to talk about one thing all day. It might be one animal, one sport or one game.

In our view, a strong interest is not a problem to fix. It is a place to start.

What studies found about interest and curiosity

How interest grows

Two researchers describe interest as growing in four phases (Hidi and Renninger, 2006). First, something catches a child's attention in the moment. If that attention is held, it can grow into a lasting interest. A child then comes back to it without being asked. It is a model that guides research, not a tested program.

A 2016 review names four approaches that seem useful for building interest (Harackiewicz, Smith and Priniski, 2016).

• Settings that catch attention.
• Links to an interest a student already has.
• Learning built around a real problem.
• Helping a student see why the topic matters to them.

It is a review by researchers, not a trial.

Seeing why a topic matters

One randomized trial took place in high school science classes (Hulleman and Harackiewicz, 2009). Students wrote about how what they learned linked to their own lives. It raised interest and grades for students who did not expect to do well. It was one trial, in one subject.

What studies found about curiosity

A US study looked at about 6,200 children followed from birth (Shah and colleagues, 2018). Children their parents rated as more curious did better in kindergarten reading and math. That held after taking self-control and other things into account. It is a link, not proof of a cause. It does not show that raising curiosity raises school results.

One paper pooled earlier studies of students' school results (von Stumm and colleagues, 2011). Curiosity and effort, together, went with better results. It is a link, not proof of a cause.

One lab study tested adults with trivia questions (Gruber and colleagues, 2014). They remembered answers better when they had been curious about them. They also remembered other things shown while they were curious. This was a study of adults, not children.

Except for the 2018 study, we read only summaries of the studies above. Nothing in the studies on this page tests Learning Success.

How to build learning out from a strong interest

• Listen for what your child talks about most.
• Find something to read about it together.
• Count, measure or sort the things that belong to it.
• Ask your child to write a short guide to it.
• Ask what they want to find out next.
• Let them teach you how it works.
• Ask how today's schoolwork links to it.

If your child only wants to talk about one game, start there. Read its rules together, or count and compare its scores.

These steps are our own practice.

We hold no trial of parents building a child's interest or curiosity at home. We hold no study that tested whether following a child's own interests raises reading or math scores.

To us, reading and math grow from being taught. In our view, an interest gives that teaching something to be about.

Keep the interest theirs

Grolnick and Pomerantz (2022) describe help that supports a child and help that controls. Supportive help takes the child's view, offers choices and solves problems together. Controlling help pushes with demands or guilt, and solves problems for the child.

Grolnick and Pomerantz also cite Ng and colleagues (2004) on children who are struggling. Children who are struggling seem more sensitive to control than children doing well, Grolnick and Pomerantz write.

Grolnick and Pomerantz write about help with schoolwork, not about a child's interests. In our view, an interest can stop feeling like theirs once it becomes homework. So leave some of it just for fun.

Our page on why motivation disappears covers what research found about rewards.

We hold no study of how pressure about grades affects a child's curiosity. In our view, pressure about grades can crowd it out. That is our position, not a finding.

When to ask for help

Each of these is a reason to ask for help on its own.

• Little change, even with steady practice and good teaching.
• Schoolwork well below what school expects.
• A teacher who raises a concern about learning.
• Extreme upset about schoolwork.
• Complete avoidance of school or learning.
• Hopelessness about learning.
• Sadness or worry that lasts.
• Significant delays in speech, language or motor development.
• A skill that was there and has gone. Our position is that a lost skill goes to a doctor first, not a tutor.

If no skill has gone, start with the teacher. Say what you are seeing at home, and what you have tried. Beyond the teacher, the right person depends on what it turns out to be about. If the work is too hard, someone who works on that school skill. If worry or mood is the thing, someone who works with children's mental health. In our view, delays in speech, language or movement are worth raising with your child's doctor. In our view, if you are worried enough to ask, a professional evaluation is worth asking about.

Any talk of hurting themselves is a same-day call to your doctor or a crisis line.
