Learning beyond exams: projects children remember

Quick test. What was the exact question in your maths exam in the second year of secondary school? What was your score?

Most people have no idea.

Now another question. Do you remember a school trip, a play you performed in, a model you built, or a project you did with friends?

Most people remember at least one — often in surprising detail. The smell of the paint. The friend who broke the model. The teacher's face when it finally worked.

That difference tells us something important about how memory and learning work.

Why do children remember projects long after they forget exam answers — and how can schools use projects to make learning last?

The forgetting curve: why cramming fails

In the 1880s, German psychologist Hermann Ebbinghaus tested his own memory by learning lists of nonsense syllables. He found that he forgot most of what he learned surprisingly quickly — a big chunk within the first day — unless he reviewed it.

This pattern is called the "forgetting curve." Modern research has confirmed the general shape many times, though the exact speed depends on what you learn and how meaningful it is.

Cramming for exams feeds the forgetting curve. Students memorise facts the night before, write them down, and forget them within days. That's why many students "pass" subjects but can't use them later.

Ebbinghaus found much of newly learned (meaningless) material is forgotten within a day without review. Meaningful learning, repeated practice and active use slow forgetting dramatically. (Ebbinghaus, 1885; replicated by Murre & Dros, PLOS ONE, 2015)

Why projects stick

Projects are powerful because they use several memory boosters at once:

• Meaning. When learning connects to something real, the brain treats it as important.
• Emotion. Pride, frustration, excitement and laughter make memories stronger.
• Action. Doing, building and making involve more of the brain than just listening.
• Repetition in disguise. In a project, students use the same ideas many times — measuring, calculating, explaining — without feeling like "revision."
• Story. A project has a beginning, problems, a climax and an ending. Our brains love stories.
• Social connection. Working with others creates shared memories.

"Education is what remains after one has forgotten what one has learned in school." — attributed to Albert Einstein (who credited an unnamed "wit")

What makes a great school project

Not every project is memorable. Copying a textbook chapter onto poster paper isn't really a project. Educators who study project-based learning, such as the PBLWorks organisation, describe features of strong projects:

• A challenging question. "How can we reduce plastic waste at our school?" is better than "Make a poster about plastic."
• Sustained inquiry. Students research over several days or weeks.
• Authenticity. The project connects to the real world.
• Student voice and choice. Students make real decisions.
• Reflection. Students think about what they learned.
• Critique and revision. Students improve their work based on feedback.
• A public product. Something shared with a real audience.

Joke break: Every group project has five members: the leader, the artist, the researcher, the one who talks at the presentation — and the one who appears on the last day asking, "So what's our topic?" Good project design makes that fifth role disappear.

10 project ideas children remember

These ideas work in African schools with modest resources. Adjust for age.

Students run a pretend (or real) market day. They make simple products, set prices, keep accounts and calculate profit. Learning: maths, money, communication. Connects to How to price creative work without guessing.

• The class market (ages 8–12)

Students map their neighbourhood: roads, shops, water points, schools, rubbish points. Learning: geography, scale, observation, citizenship. Inspired by community mapping like Map Kibera — see What happens when a neighbourhood solves its own problem.

• Our neighbourhood map (ages 10–15)

Students interview elders about life "before," record it, and create a class book or audio collection. Learning: history, language, interviewing, respect. Connects to The value of keeping African stories in local languages.

• Grandparents' stories (ages 10–16)

Plant vegetables, measure growth, track water use, cook the harvest. Learning: biology, maths, nutrition, responsibility.

• The school garden (all ages)

Teams build filters with sand, gravel, charcoal and cloth, and compare results. Learning: chemistry, engineering, health.

• The water filter challenge (ages 11–16)

Build an oven from a box, foil and plastic; try to warm food. Learning: energy, heat, design. (Supervise closely.)

• The solar oven (ages 11–16)

Students write and record a short radio programme on a local issue. Learning: writing, speaking, research, media literacy.

• The school radio show (ages 12–18)

Make art from waste — inspired by Beninese artist Romuald Hazoumè, famous for masks made from plastic jerrycans. Learning: art, environment, creativity. See The artists telling stories of today's Benin.

• Recycled art exhibition (all ages)

Design a robot or device that helps with a real school problem. Learning: engineering, coding, teamwork. See How to start a school robotics club with one kit.

• Build a robot helper (ages 12–18)

Students investigate viral messages and publish results on a school board. Learning: critical thinking, research, citizenship. See A practical way to check a claim about Africa.

• The fact-check desk (ages 13–18)

"But the exams…"

Exams are real, and students need to pass them. The good news: projects and exam success are not enemies.

• Projects build deeper understanding, which helps students answer unfamiliar exam questions.
• Projects can include exam-style tasks: short written explanations, calculations and diagrams.
• Teachers can link projects directly to syllabus topics (volume, ecosystems, energy, history).
• A term might include one project plus regular lessons and revision.

Some countries are also reforming assessment. Kenya's Competency-Based Curriculum, for example, includes more practical and project-based assessment than the old system. Many education systems in Africa are discussing similar shifts.

How to assess a project fairly

Use a simple rubric, shared with students at the start:

• Knowledge (Did they use the right concepts?)
• Process (Did they research, test and improve?)
• Collaboration (Did everyone contribute?)
• Product (Is the final result clear and well made?)
• Reflection (Can each student explain what they learned?)

Add individual tasks — a short test or personal reflection — so that group work doesn't hide individual learning.

Tips for teachers starting out

• Start with one short project (one or two weeks).
• Use local, free materials.
• Plan the final "show" early: a presentation day, exhibition or radio broadcast.
• Invite parents. Children work harder when family is watching.
• Take photos. They're great for motivation and for convincing school leaders.
• Reflect afterwards: what worked, what didn't?

A project story (illustrative)

In an illustrative primary school in Parakou, a teacher we'll call Mme. Bio (illustrative) wanted her class of 10-year-olds to understand fractions. Instead of starting with the textbook, she announced: "Next Friday, we are opening a class restaurant."

The children had to plan a menu, divide recipes for different numbers of people, cut fruit into halves and quarters, share costs, and calculate change. One group discovered that "half of a half" is a quarter — not by being told, but by cutting a papaya. Another group realised they had bought too little bread because they forgot to multiply by the number of guests.

On restaurant day, parents came to "eat" (small portions, big smiles). The children served, counted money and gave change. At the end, Mme. Bio gave the regular fractions test. The class did better than her previous classes — but more importantly, months later, children still said things like, "That's like when we cut the papaya."

The project took about six lessons. It covered the fractions syllabus, some measurement, money and a lot of teamwork. And it created a memory the class will likely keep for years.

Projects and the skills employers want

Beyond memory, projects train the skills employers keep asking for. Business surveys across the world — including the World Economic Forum's Future of Jobs reports — list skills like analytical thinking, creative thinking, resilience, curiosity and teamwork as top priorities.

Exams mostly measure what you can recall alone, in silence, in two hours. Jobs mostly require you to solve unclear problems with other people over days and weeks. Projects are much closer to real work. Read What young workers want from their first job to see the other side of that story.

Memories are the real report card

Years from now, your students won't remember their exam scores. They'll remember the day the water filter finally worked, the elder whose story made the class cry, or the robot that crashed spectacularly into the headmaster's shoe.

Those memories carry knowledge with them. That's learning that lasts.
