Why Making Mistakes is Essential in Bilingual Learning

At ICS Côte d'Azur, we believe that the journey to fluency is paved with "beautiful mistakes." In our international environment, children navigate between languages daily, and while it might be tempting to aim for perfection, the research is clear: errors are the engines of cognitive growth.
As our Head of Early Years beautifully puts it:
A toddler learns to walk by falling over; they get up time and again until, eventually, everything clicks into place. Learning a language follows the same rhythm. Every child has the right to make mistakes, as these are the very stepping stones they need to reach true understanding.
-Morgane Scherlen, Head of Early Years
Here is why embracing the "oops" moments is the secret to mastering a second language in our primary and early years programmes.
1. Mistakes Build "Brain Plasticity"
When a child makes a mistake—such as applying a French verb ending to an English word—their brain isn't failing; it is testing a hypothesis. This process, known as Interlanguage, is a vital stage where the brain maps out the rules of both languages.
- The Science: Every time a student is corrected or realises an error, their neural pathways strengthen. It forces the brain to "re-wire" and refine its understanding of linguistic structures.
- The Result: Higher cognitive flexibility and superior problem-solving skills that extend far beyond the classroom.
2. Lowering the "Affective Filter"
The greatest barrier to learning a language isn't grammar; it is anxiety. Linguist Stephen Krashen’s "Affective Filter" hypothesis suggests that when students are afraid of making mistakes, their brains physically "block" new information.
- At ICS Côte d'Azur: We foster a low-stress environment where "having a go" is celebrated more than being flawless.
- The Benefit: When children feel safe to fail, they speak more often. This increased output leads to faster natural acquisition. When the filter is low, the brain is fully open to absorbing the nuances of a new tongue.
3. The Power of Trial and Error in Social Play
For our younger learners, language is a tool for connection. In the playground, a child might use the "wrong" word to ask for a toy. If the peer doesn't understand, the child quickly adapts, trying a gesture or a different word.
This negotiation of meaning is where the most profound learning happens. By misstepping and then correcting in real-time, children develop a deep, intuitive grasp of how language functions in the real world. They aren't just memorising vocabulary; they are learning the art of communication.
4. Risk-Taking and the Growth Mindset
Bilingualism is as much about character as it is about vocabulary. Encouraging mistakes teaches children resilience—a core value at our school. By treating errors as data points rather than failures, we help students develop a Growth Mindset. They learn that fluency is a marathon, not a sprint, and that every "wrong" word is a necessary step closer to the right one.
Tips for Parents at Home
- Don't over-correct: Focus on the message, not the mechanics. If they say, "I goed to the park," reply with, "Yes, you went to the park! Was it fun?"
- Celebrate the effort: Praise your child for attempting a complex sentence, even if the syntax was a bit muddled.
- Model the behaviour: Let your children see you struggle with a new phrase in a second language. Show them that even adults find learning challenging and that persistence is the key to success.
