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 Alzheimers disease better compared to people who have only mastered one language. Alzheimers is a progressive mental deterioration that can begin in middle or old age due to generalized brain degeneration.

The study involved 85 people with Alzheimers C 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 C a set of necessary behavioral cognitive processes that include problem-solving, working memory, reasoning and attentional control. The study also noted that the bilingual Alzheimers 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 Alzheimers 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 Alzheimers 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 Ins 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.

  • Expressing love around the world: Interesting facts and how to say "I love you" in different languages

    Love is a universal language that transcends borders, cultures and languages. For those learning another language, understanding how to express love in various tongues can be both fascinating and useful. Whether you're planning to travel, connect with friends from different backgrounds, or simply expand your linguistic repertoire, knowing how to say "I love you" in different languages as well as the cultural context, can be a beautiful way to show appreciation and affection. Let's take a look at some of the many ways to express this timeless sentiment and some interesting facts.

    1. Cultural nuances:

    In many cultures, the way you express love can carry different weights and meanings. For example, in Japanese, "ۤƤ" (aishiteru) is a very strong expression of love, often reserved for serious relationships, whereas "ä" (daisuki) is more commonly used among friends and family.
    However, French, often called the language of love, uses "je t'aime" to express love as a romantic phrase that can be used for both partners and close family members.

    2. Gender differences:

    Some languages have gender-specific ways of saying "I love you." For instance, in Arabic, "????" (a?ibbuka) is used when a woman says "I love you" to a man, and "????" (a?ibbuki) is used when a man says it to a woman. Similarly, in Hindi, men say "??? ????? ????? ???? ???" (main tumse pyaar karta hoon) and women say "??? ????? ????? ???? ???" (main tumse pyaar karti hoon).

    3. Formal vs. informal:

    Some languages have formal and informal ways of expressing love. In Spanish, "te amo" is more formal and used for romantic love, while "te quiero" is more casual and can be used for friends and family.

    Learning English as a second language is a journey that can be fun and tough. A key part of this journey is knowing your current skill level. The Global Scale of English (GSE) helps learners check their skills. The GSE is a scale from 10 to 90 that measures English ability. It gives clear information about what learners can do at each level. In this blog, well look at how to find out your English level using GSE scores, levels, and "I can..." statements.

    Why understanding your English level matters

    You may wonder, Why is it important for me to know my language level? If you start studying without knowing your skill level, you might feel overwhelmed, frustrated, or find learning too easy and be put off or not make any learning progress.
    Knowing your English level helps you in many ways, such as to:

    1. Set realistic goals: Tailor your learning objectives to your current abilities.
    2. Choose appropriate materials: Select books, courses, and resources that match your proficiency.
    3. Track progress: Measure improvement over time and stay motivated.

    GSE levels and what they mean

    The GSE levels range from Starter to Expert, each with specific "I can..." statements that describe what you should be able to do at that level. Heres a breakdown of each level, along with some practical examples:

    Planning effective ESL lessons for the upcoming year: Tips and ideas for teachers

    By Sam Colley
    Reading time: 4 minutes

    As the new year approaches, it's the perfect time to reflect on our teaching practices and plan engaging, effective lessons for our English as a Second Language (ESL) students. Thoughtfully crafted lesson plans can make a significant difference in the learning outcomes and engagement levels of your students. Whether you're teaching young children, teenagers, or adults, the principles of effective lesson planning remain consistent. Here are some ideas, hints and tips to help you create dynamic and successful ESL lessons for students of all ages.

    Start with clear learning objectives

    Begin each lesson with clear, achievable objectives. What do you want your students to learn by the end of the lesson? Objectives provide a roadmap for both you and your students, ensuring that everyone is focused and aware of the goals. For example, an objective might be "Students will be able to use past tense verbs to describe their weekend activities." Clear objectives provide direction and help you measure student progress.

    Incorporate a variety of activities

    To cater to different learning styles and keep students engaged, incorporate a mix of teaching methods and activities. Here are a few ideas:

    • Listening: Use audio recordings, songs, or podcasts to improve listening skills.
    • Speaking: Organize pair or group discussions, role-plays, or presentations to enhance speaking abilities.
    • Reading: Provide a variety of texts such as articles, short stories, or dialogues.
    • Writing: Assign tasks like journal entries, essays, or creative writing exercises.
    • Homework activities: For something outside of the classroom, a nature walk or a recipe can be used to help learn specific vocabulary.

    Use authentic materials

    Authentic materialssuch as newspapers, menus, brochures and videosexpose students to real-world language and contexts. These materials can make lessons more interesting and relevant, helping students see the practical application of their language skills. Even better, theyre everywhere, so easy to find. Here are some more suggestions for how to select and use authentic materials in your English language teaching.

    Integrate technology

    Teachers are already used to leveraging technology to enhance lessons utilizing online resources, language learning apps and interactive platforms to create a dynamic learning environment. Why not take this a step further by using AI to create your own resources. Take a look at our blog on How to make the most of AI in the classroom for some more ideas.
