Can Schools Teach Kids to Spot Health Lies? A Rwanda Study Says Yes!
Hey there! So, I was digging into some research the other day, and something really caught my eye. We live in a world absolutely *flooded* with health information, right? And let’s be honest, not all of it is, shall we say, *accurate*. You see stuff online, hear things from friends, maybe even catch snippets on the news that make you scratch your head. How do you figure out what’s legit and what’s just… well, bunk?
This isn’t just a minor inconvenience; acting on bad health info can be genuinely harmful and a total waste of time and money. The folks at the Informed Health Choices (IHC) network saw this problem loud and clear. Their big mission? To help people, especially young people, get better at figuring out health claims and making smart choices.
What’s the Big Idea?
The IHC network has been working for about a decade on this. They realized that while adults need help navigating this info jungle, teaching kids early could make a massive difference. They’ve developed tools and lessons for primary school kids and even podcasts for parents. But they didn’t stop there. They looked at secondary school – that crucial age (around 13-15) where young minds are developing fast and starting to make more independent decisions.
They teamed up with people in East Africa, specifically Kenya, Rwanda, and Uganda, to figure out the best way to teach these critical thinking skills in those schools. They used a cool approach called human-centered design, working *with* students and teachers to create digital lessons that would actually work and be easy to use in that context. The goal wasn’t just to teach facts, but to teach *how to think* about health claims – things like understanding evidence, recognizing unreliable information, and weighing options.
Taking it to School: The Intervention
So, what did this look like? They created a set of ten 40-minute lessons. These lessons focused on nine key concepts – basically, principles for thinking critically about health claims and decisions. Think of it like a toolkit for your brain to sort through health noise. These weren’t just extra homework; they were designed to be taught by trained teachers right alongside the usual school stuff.
They tested these lessons in trials across the three East African countries, and guess what? Immediately after the lessons, they saw positive effects! The students who got the intervention were better at critical thinking about health than those who just followed the regular curriculum. Pretty neat, right?

The Rwanda Experiment: A Year Later
But here’s the real kicker: Does it stick? Learning something new is great, but does that knowledge and skill stay with you over time, especially when you’re not actively using it every day in class? That’s what this particular study in Rwanda wanted to find out. They went back to the schools a whole year after the intervention finished to see how the students were doing.
They set up a proper scientific study – a cluster-randomized trial. This means they randomly assigned whole schools (not individual students) to either get the special IHC lessons (the intervention group) or just continue with their normal classes (the control group). They did this in 84 schools across 10 districts in Rwanda, making sure to spread it out across different areas and school types (public, private, etc.).
After a year, they gave the students and teachers a test called the Critical Thinking about Health Test. This test was designed to see if they could understand and use those key concepts from the lessons. The main thing they looked at was the proportion of students who got a “passing score” – meaning they answered at least 9 out of 18 questions correctly.
The Results Are In!
Okay, drumroll please… The results were pretty clear. A year after the intervention, a significantly higher percentage of students in the schools that got the IHC lessons achieved a passing score on the test compared to the students in the control schools.
- In the intervention group, 50.5% of students passed the test.
- In the control group (usual curriculum), only 19.5% of students passed.
That’s a huge difference! The adjusted difference was 32.2%, meaning students who got the lessons were over 32% more likely to pass the test a year later. The statistics nerds among us will appreciate the adjusted odds ratio of 7.6 – basically, students in the intervention group had about 7.6 times higher odds of passing! This difference was highly statistically significant (p < 0.0001).
And it wasn’t just about passing. More students in the intervention group also achieved a “mastery score” (getting 14 or more questions right), and their average scores were much higher too.
It wasn’t just the students who benefited. The teachers in the intervention schools also showed much higher passing and mastery rates on the test compared to the teachers in the control schools. This makes sense, as they were trained to teach the material!

What About Retention?
Now, remember how I mentioned they also looked at the results immediately after the intervention? They compared those results to the results after one year. Turns out, while the effect was still very strong after a year, it was a *little* smaller than it was right after the lessons finished.
Immediately after the intervention, the difference in passing scores between the groups was 37.2%. A year later, it was 32.2%. This means there was some “decay” in the proportion of students in the intervention schools who got a passing score (it went from 58.2% right after to 50.5% a year later). However, the proportion of students passing in the control schools stayed pretty much the same (around 19.5%).
So, while not everyone retained everything perfectly, about half the students who got the lessons could still pass the critical thinking test a year later, which is pretty impressive, especially compared to the control group.
Digging Deeper
The study also looked at a few other interesting things. Did the intervention work better in schools that usually performed well academically compared to those that didn’t? Nope, the effect was similar across both types of schools. What about students’ English reading skills (since the test was in English)? Students with lower English proficiency were less likely to pass overall, but the intervention *still* had a positive effect on them compared to their peers with similar low proficiency in the control group. This suggests the lessons were beneficial even for those facing language barriers.
They also asked students in the intervention group what they thought about the lessons. Over 80% liked them, over 66% found them easy to understand, and over 84% found what they learned helpful. Sounds like the students were on board!

The Big Picture e What’s Next
So, the big takeaway? This study provides strong evidence that teaching critical thinking about health in secondary schools in Rwanda using the IHC intervention is effective, and the benefits *last* for at least a year. This is a pretty big deal because there hasn’t been much research showing long-term effects of this kind of training in schools.
However, the study also highlights that there’s room for improvement, especially in helping students retain the knowledge and skills even better. The researchers suggest a few ideas:
- Adding follow-up lessons to reinforce the concepts learned.
- Giving students more direct access to the learning materials (printed or digital).
- Spending more time on the lessons.
- Integrating these critical thinking skills directly into the regular school curriculum and even national exams. Making it part of what’s tested could really emphasize its importance.
Similar studies in Kenya and Uganda also showed positive results after one year, suggesting these findings are likely applicable across East Africa in schools following the national curriculum. While the study had some limitations (like some students and teachers not being available for the follow-up), the researchers did analyses that suggest these limitations didn’t significantly skew the main findings.
Ultimately, empowering young people to think critically about health information isn’t just about getting a good score on a test; it’s about giving them the tools to make safer, healthier choices throughout their lives. This study shows it’s possible, and that’s incredibly encouraging!
