The Brain of the Bilingual Learner

In the not-so-distant past, it was believed that becoming bilingual at a young age could confuse children and even weaken development in their home language! Thankfully, research over the years has shown quite the opposite; there are significant benefits to children learning multiple languages. So, what is happening in the brains of young language learners that leads to these benefits?

An article on  Bilingual Brains by Dr. Judy Willis , a neurologist and teacher whose research influenced the development of GrapeSEED, highlights the research of Ellen Bialystok, a Canadian psychologist and professor concentrating on bilingualism and cognitive development in children. Bialystok compared the brain scans of 6-year old children from bilingual and monolingual homes and found that higher levels of executive function (the management of cognitive processes, including working memory, reasoning, task flexibility, problem solving, planning and execution) could be seen in the fMRI scans of the bilingual children’s brains. These scans showed increased activity in the prefrontal cortex, the part of the frontal lobe associated with thinking and awareness and also where Broca’s area, which is linked to speech production and language comprehension, is located.

Dr. Willis goes on to explain that the interpretations of researchers, such as Bialystok, “suggest the bilingual brain is highly engaged in the cognitive challenge of evaluating between the two competing language systems. This requires executive function attention selecting and focusing on the language being used while intentionally inhibiting the activity of the competing language system.” So, in other words, bilingual children must use their brains to filter out the language that is not in use and deliberately focus on the one that is. Then, she says, “Their brains need to evaluate and determine not only the meaning of words, but also which patterns of sentence structure and grammar apply and recognize nuances of pronunciation unique to the language of focus.” Monolingual speakers do not have these extra steps in processing the language. The exercise in executive function that bilingual children perform when they are switching between languages gives their brain a great workout! And as a result, bilingual children scored higher on cognitive testing than their monolingual peers.

Another study  that looked at neuroimages of bilingual speakers found that their posterior supramarginal gyrus, the area of the brain associated with vocabulary acquisition, had more gray matter density than monolingual speakers, signaling that the brain is growing – “bilingualism actually reshapes the brain.” The following image shows the gray matter density in bilingual learners.

This is further proof that stimulating our young learners’ neural networks with focused practice can strengthen their cell pathways and help promote language acquisition and

literacy development! The GrapeSEED curriculum provides a rich environment of vocabulary, songs, stories, action activities, chants, poems and more for your English Language Learners. Give your students a healthy brain workout and watch them grow in oral language skills, literacy, and confidence!

Have you noticed that the month of March brings a noticeable and welcomed shift? Daylight sticks around a bit longer, schedules fill with activities, and students arrive at school each morning with a renewed sense of energy. For young multilingual learners, springtime provides a powerful opportunity; not to reinvent instruction, but to lean into what already works and let that momentum carry learning forward. By this point in the school year, students have built familiarity with classroom routines and expectations. This consistency is especially important for language learners because predictable structures—songs, chants, stories, movement, and daily oral practice—create a safe environment where students feel confident participating, even when the language feels challenging. In March, that confidence often begins to show more clearly! In March, teachers are noticing students: joining in more quickly using phrases spontaneously engaging more willingly in partner activities These moments can be easy to overlook, but they are significant indicators of language growth. Oral language development doesn’t always arrive in neat, measurable steps…it emerges through repeated exposure, joyful practice, and meaningful interaction over time. As spring energy rises (spring fever, anyone?), maintaining consistent routines can actually help classrooms feel calmer and more productive. Students know what comes next, how to participate, and what success sounds like. Rather than pulling back on structured language practice, this is the moment to protect it. Daily routines…spoken language, movement, music, and shared stories…anchor learners while giving them space to take risks. March is also a reminder that language learning is cumulative. The repetition that felt slow in the fall often pays off in the spring, when students are ready to use what they’ve internalized. When instruction continues to spiral skills like phonemic awareness, vocabulary, comprehension, and oral fluency, students are supported without feeling pressured. As the school year speeds up, this is the perfect time to take a deep breath and to notice progress. So, take time to celebrate participation, effort, and small breakthroughs to help your multilingual learner students see themselves as the capable language learner they are, and encourage them to keep moving forward! Are you ready to learn more about how GrapeSEED can help your multilingual learners succeed in ways big and small?

February is a unique moment in the school year: routines have been established, students are settled, and teachers can clearly see areas of growth as well as emerging needs. It’s also a natural pause before the busy spring months. All of this makes February an ideal time to reflect and to look ahead. For multilingual learners, what happens after the school year ends matters more than we often realize. The Summer Learning Opportunity Extended breaks can unintentionally slow language development, particularly in listening, vocabulary, and verbal confidence. However, when summer instruction is intentional and well designed, it can do more than maintain progress—it can accelerate it. The key is ensuring summer learning feels inviting, engaging, and developmentally appropriate. What Works for Young Language Learners Effective summer language programs share common elements that support growth without feeling like “more school”: A low-stress environment where students feel comfortable taking risks with language Consistent exposure to English through stories, songs, shared reading, and movement Natural repetition and routine that strengthen foundational English language skills Multi-sensory learning experiences that keep students engaged and motivated When language is experienced rather than practiced in isolation, children remain curious, confident, and connected. Why February Is the Time to Think Ahead February isn’t about making immediate decisions—it’s about asking the right questions: How can summer learning support language development without burnout? What experiences will help students feel successful and excited to learn? How can summer instruction align with the strengths of our school-year approach? Exploring these questions now allows schools to plan thoughtfully rather than reactively. A Season for Planting Ideas Strong summer programs build on what young learners love most—music, stories, movement, and interaction—while quietly reinforcing the language skills they need to grow. February offers the space to imagine a summer experience that supports continuity, confidence, and joyful learning long after winter fades.

If you’re an elementary teacher working with multilingual learners, you already know your work is full of heart, hustle, and highlighters. But let’s be honest—supporting language learners takes a lot of energy. That’s why self-care isn’t a luxury. It’s a must. You’re juggling language development, academic growth, cultural connection, and emotional support. And while your students are growing every day, you need time to recharge, too. Here’s a quick self-care recipe to keep your cup full: ๐Ÿงก Smiles: Find Joy in the Little Things Celebrate the small wins: a new vocabulary word, a student’s laugh, a kind moment. Write one highlight on a sticky note each day. It’s a mood booster—and a reminder that you’re making a difference. ๐ŸŽ Snacks: Fuel Your Body (and Soul) Don’t skip lunch! Keep a stash of healthy snacks (and maybe a treat or two) nearby. Food is fuel, and sometimes chocolate is emotional first aid. ๐Ÿง  Sanity: Protect Your Peace Say no to that extra committee if you’re overwhelmed. Take 5 minutes to breathe or stretch between lessons. Step outside during a break of any kind, even for just a second or two. Talk to someone who “gets it”—sharing helps lighten the load. You Matter Your students need you AND they also need you to be okay. When you take care of yourself, you’re showing them how to care for themselves, too. So go ahead, teacher: smile, snack, and protect your sanity. You can’t do it all , but you CAN do a lot more when you’re well. At GrapeSEED English for Children, we value teachers and work to make certain that those using our curriculum feel supported. With a personal Professional Learning Specialist that teaches can communicate with anytime, a teacher portal, on-demand PDs and so much more, we’ve got our teachers covered!
