Being bilingual can help keep your brain in good condition

Learning and understanding a new language is one of the most challenging things that your brain can do. But as well as the advantage of acquiring another language, it appears that the effort of giving your brain a good workout today by being bilingual could keep it in better condition in later life.

Research led by Dr. Daniela Perani, a professor of psychology at in Milan, found that people who speak two or more languages seem to weather the ravages of Alzheimer’s disease better compared to people who have only mastered one language. Alzheimer’s is a progressive mental deterioration that can begin in middle or old age due to generalized brain degeneration.

The study involved 85 people with Alzheimer’s – half of whom spoke both German and Italian and half who spoke only one language. The researchers found that bilingual patients had greater connectivity in key brain areas. This was especially in the part of the brain that governs “executive control” – a set of necessary behavioral cognitive processes that include problem-solving, working memory, reasoning and attentional control. The study also noted that the bilingual Alzheimer’s patients showed less severe symptoms of the disease.

The study concluded: “Our findings suggest that the effects of speaking two languages are more powerful than both age and education in providing a protection against cognitive decline.”

Bilingualism and the brain

Although Alzheimer’s disease is currently incurable, the study supports a popular theory that people who have higher levels of education function longer with little manifestation of the illness. Part of the reason why bilingual brains may be better at resisting Alzheimer’s could be due to a lifetime of switching between languages daily.

Learning and speaking more than one language changes how the brain carries out tasks that require focus and concentration on a certain piece of information without being distracted. It can also increase the density of white matter (connections) in the brain, meaning that there are more connections between brain parts, thus making this part of the brain more resistant to degeneration.

This is supported by a study conducted by a team led by Professor Ana Inés Ansaldo at the , which suggests that bilingual people have more robust and more efficient brains compared to those who only speak one language. This is one of the reasons why a bilingual brain can be a buffer against aging and dementia.

They recruited elderly people, half of whom spoke only one language and the other half who had learned a second language between the ages of 11 and 18. All performed equally well on a task that involved focusing on an object's color while ignoring its position, but brain scans revealed a big difference in how they processed the task.

“While bilinguals were recruiting very specific brain areas and a small number of areas to perform the task, monolinguals were recruiting a much larger number of areas that were consuming much more resources. And the networks they were using were very, very complex,” says Professor Ansaldo. “That led us to think that the bilingual brain was more efficient in terms of the amount of resources that bilingual people require to do complex tasks as opposed to the monolingual brain.”

The study concludes that bilingualism shapes the brain in a different way or how people approach complex tasks. It could be because bilinguals must inhibit the language they are not using to focus on the one that they are using.

    How the GSE can help teachers personalize activities

    By

    Reading time: 4.5 minutes

    Teaching is an art form that thrives on adaptation and personalization. When dealing with language instruction, ensuring that each student is engaged and effectively learning is of paramount importance. In my experience as a teacher, I have learned that we should always teach our students rather than the coursebook or the syllabus. I think most teachers would agree with this.

    However, it may be challenging to adapt activities to cater to our learners’ needs. What does personalizing an activity mean? How can we make it more accessible to our English learners? One would think that making the answers more obvious can be the way to go. Yet, this does not really help students learn and make progress. That's where the Global Scale of English (GSE) comes in as a valuable tool for personalizing teaching activities.

    The essence of personalized learning

    Personalizing an activity in language teaching does not simply mean making the responses more obvious. Instead, it's about tailoring the exercise to elevate the student's learning experience and potential for progress. This demands an insightful approach during the preparation phase of any given lesson.

    Utilizing the GSE in language teaching

    Let’s analyze this listening activity at A2 level for a group of adults:

    Audio script example:

    Emma: Are you working on the Media project?

    Vic: Yes. I may start working on a new project in a couple of weeks, but for now I’m writing the objectives for Media. Why?

    Emma: Well, Adam wants to see the photos for the project. He needs them for the ads.

    Vic: Oh, they’ll be ready next week. OK?

    Emma: Awesome! Thanks. Any plans for the weekend?

    Vic: Well, I have to work on Saturday. We’re taking the Media pictures in the morning, but we’re just going to have fun at the beach in the afternoon.

    Emma: Nice!

    Vic: What about you? What are you doing this weekend?

    Emma: I’m going to a concert on Sunday at 3 pm.

    Vic: That sounds fun!

    Listen and write T (true) or F (false)

    1. Vic is working on a new project.

    2. Vic is working on Saturday morning.

    3. Emma is going to a concert on Sunday evening.

    GSE Descriptors

    Upon dissecting this example by the GSE descriptors, we can identify the learning objectives that align with an A2 level:

    • Can identify simple information in a short video, provided that the visual supports this information and the delivery is slow and clear. (GSE 30)

    • Can identify basic factual information in short, simple dialogues or narratives on familiar everyday topics, if spoken slowly and clearly. (GSE 32)

    • Can understand the main information in short, simple dialogues about familiar activities, if spoken slowly and clearly.(GSE 33)

    • Can identify key information (e.g., places, times) from short audio recordings if spoken slowly and clearly. (GSE 33)

    We know that learners should be given a global task first for overall listening, which is also one of the communicative objectives in the Global Scale of English:

    The art of goal setting

    By

    Reading time: 4 minutes

    Dr. Ken Beatty defines goals and explains why we should think of them as doors to open rather than fixed targets.

    Goals as doors

    My eldest son, Nathan, failed to achieve the biggest goal of his life: becoming a garbage truck driver. It's hardly surprising - he was only four years old at the time. His ambition likely dissolved once he realized that garbage trucks sometimes smell bad. Before then, he'd mostly observed them from the safety of our apartment window.

    As is the case with most people, his goals have changed. Completing his degree in international economics, hoping to work in technology startups until he forms one himself. Or maybe not. Goals evolve.

    Researchers and teachers have known for decades that goals are vitally important motivations in general education and language learning. After examining 800+ studies, Hattie (2009) identified goals as among the most powerful instructional interventions for improving student success.

    The basic message is that goals are good. However, other researchers (Rowe, Mazzotti, Ingram, & Lee, 2017) suggest that teachers have trouble embedding them in lessons.

    Part of the problem might be in finding a way to visualize goals. Goals are often pictured as archery targets or soccer nets, but a more useful metaphor is a door. When we have a goal, we may not fully understand it until we enter into the goal, as if it were a room, inevitably finding choices of other doors leading off in other directions.

    Understanding where goals come from

    Before we start to set goals for our students, it's important that we have a degree of self-awareness and understand where our own attitudes and ideas come from.

    As teachers, we tend to resemble the people who inspired us most. Our own teachers, good and bad, shape our attitudes toward teaching and language-learning goals.

    Who was your favorite teacher? In my case, my all-time favorite teacher was Mr. Chiga, who, in 1970, taught me Grade 7 and was about to retire. He was a Renaissance man. Short and tough with fingers like cigars, he would occasionally lead us from the playground up two flights of stairs to our classroom… walking on his hands. Yet these same hands were delicate enough for his hobby of making violins, a fact I only learned later, because, unlike me, Mr. Chiga was modest.

    Mr. Chiga loved literature and taught us Greek and Roman history with a sense of joy that has never left me. One would think that his educational goals would be a perfect foundation for my own. Perhaps. But a quick check on the timeline shows that if he was about to retire in 1970, he was probably born in 1905 and likely graduated from teachers' college around 1925.

    It's ironic that although my Ph.D. is in the area of computer-assisted language learning, my favorite teacher began his career two years before the invention of the television, and, moreover, all his teachers would have been born in the 1800s.

    It's a long story to make a short point: as teachers, we need to reflect on where our teaching and learning goals come from and question them. We also need to avoid those things that our least favorite teachers did.

    Setting goals

    Are the goals we set for our students sometimes too low? Undoubtedly.

    As a Grade 11 student, my only ambition in life was to take a two-year photo technician course. My counselor discouraged me, saying I wasn't academic enough and suggested a job at the wood mill instead. In a sense, he closed a door.

    I switched schools where another favorite teacher, Mr. Ferguson, patiently kept me after school for six weeks, teaching me how to write essays and, by extension, how to think. He dangled the motivation of a university education before me and set me on my path there. And that was a door opened.

    So what's the lesson here? More than just knowing where goals come from, we also need to be aware of the power of goal setting and how it can drastically alter a particular student's life trajectory.

    Closing doors, rather than opening them, often stunts growth and limits possibilities. It can even lead to students forming life-long assumptions about themselves that just aren't true - "I'm no good at math," "I'm not cut out for independent travel", etc. Opening doors, however, can bring our students entirely new perspectives on life.

    Expecting goals to change

    When it comes to changing goals, there are a number of factors to take into account, including forming a better sense of self. We might start off with many ambitions but we measure ourselves against the realities of our skill sets and modify our goals.

    For example, a student who experiences a lot of success in learning English is more likely to consider careers that require it. Teachers, too, are more likely to offer direction: "You write very well. Have you considered a career in journalism?"

    Today, countless jobs require a second language or provide better promotion opportunities for students who speak two or more languages. Yet, students oriented toward employment opportunities may have difficulty understanding the long-term advantages of learning a second language if specific jobs are not on their radar.

    This leads to two questions:

    • What goals should we help students set for themselves?
    • And how should teachers suggest them?

    Many goals are based on the educational standards that govern our profession. The Global Scale of English (GSE), in particular, is helpful to both textbook writers and teachers in identifying language goals and provides teachers with detailed steps to achieve them.

    But beyond such standards are those two magic ingredients that teachers share with language learners: joy and motivation.

    Teachers spread joy in learning by example, making language learning engaging and pleasurable. Teachers also motivate students by helping them identify personal goals, giving them reasons why language proficiency is not just worthwhile in general but is perhaps one key to future success.

    It might even lead to a job driving a garbage truck.
