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.

    What is Content and Language Integrated Learning?

    By Joanna Wiseman
    Reading time: 4 minutes

    Content and Language Integrated Learning (CLIL) is an approach where students learn a subject and a second language at the same time. A science course, for example, can be taught to students in English and they will not only learn about science, but they will also gain relevant vocabulary and language skills.

    It’s important to note that CLIL is not a means of simplifying content or reteaching something students already know in a new language. CLIL courses should truly integrate the language and content in order to be successful – and success is determined when both the subject matter and language is learned.

    Who is CLIL for?

    CLIL can work for students of any age, all the way from primary level to university and beyond. So long as the course content and language aims are designed with the students’ needs in mind, there is no limit as to who can benefit from this teaching approach. However, it is most commonly found in primary and secondary school contexts.

    What are the main benefits of CLIL?

    Many teachers see CLIL as a more natural way to learn a language; when a subject is taught in that language there is a concrete reason to learn both at the same time. And as students have a real context to learn the language in, they are often more motivated to do so, as they can only get the most of the content if they understand the language around it.

    Moreover, being content focused, CLIL classes add an extra dimension to the class and engage students, which is especially advantageous in situations where students are unenthusiastic about learning a language.

    CLIL also promotes a deeper level of assimilation, as students are repeatedly exposed to similar language and language functions, and they need to produce and recall information in their second language.

    Furthermore, it has the advantage that multiple subjects can be taught in English, so that students’ exposure to the language is increased and their language acquisition is faster.

    CLIL also encourages students to develop 21st century skills, including the ability to think critically, be creative, communicate and collaborate.

    What are the challenges of CLIL?

    As CLIL is subject-focused, language teachers may also have to develop their own knowledge of new subjects in order to teach effectively.

    They must also structure classes carefully so that the students understand the content of the lesson, as well as the language through which the information is being conveyed.

    And when it comes to classroom management, educators need to be very aware of individual student understanding and progress.

    It’s therefore important to consistently concept check and scaffold the materials to be sure both the language and content are being learned.

    How can you apply CLIL to your class?

    It’s important to have a strategy in place when applying CLIL in your courses. One of the key things to remember is that the language and subject content are given equal weight and that it shouldn’t be treated as a language class nor a subject class simply taught in a foreign language.

    According to Coyle’s 4Cs curriculum (1999), a successful CLIL class should include the following four elements:

    • Content – Progression in knowledge, skills and understanding related to specific elements of a defined curriculum
    • Communication – Using language to learn whilst learning to use language
    • Cognition – Developing thinking skills which link concept formation (abstract and concrete), understanding and language
    • Culture – Exposure to alternative perspectives and shared understandings, which deepen awareness of otherness and self

    Using a number of frameworks can help you prepare your lessons and make sure activities are challenging yet achievable for your learners.

    Bloom’s Taxonomy, for example, classifies learning objectives in education and puts skills in a hierarchy, from Lower Order Thinking Skills (LOTS) to Higher Order Thinking Skills (HOTS).

    In the diagram below, you can see the levels increasing in complexity from the base up to the triangle’s peak.

    How do different motivations change how students learn English?

    By Steffanie Zazulak
    Reading time: 4 minutes

    Students all over the globe learn English for many reasons. Some of these motivations may come from the students themselves – perhaps they are learning because they are travelling to an English-speaking area, or they want to be able to converse with English-speaking friends and colleagues. Other reasons for learning could include meeting school requirements, studying abroad, or progressing their careers.

    As well as different reasons to learn English, there are also different goals. Many students are still focused on becoming fluent in English, and we are seeing an increase in people who want to learn the language for specific reasons. For example, immersing themselves in a particular culture or simply being able to order from a menu while travelling abroad.

    Teachers are focusing on these personal needs to help students achieve their actual goals. It’s likely you’ve already spoken to your students about why they want to learn English. Understanding this is important as different motivations can influence a student’s attitude towards learning the language – and it may be necessary for you to adapt your teaching strategies for different groups of learners.

    Teaching English to different groups of learners

    Let’s meet some different groups of students, learn a little more about their motivations and explore whether different motivations alter how students learn English. You may recognise some of these learners in your classes.

    1. Adult learners

    These students are learning English for pleasure or personal reasons. It might be because of travel, social or family reasons or perhaps because a better grasp of English might assist them with their careers. There are also adult learners who could be learning English as an immigration requirement.

    For example, 23-year-old Alice decided to learn English so she could meet people and have more meaningful interactions with her English-speaking neighbours. She says: “I was very shy and not very confident in speaking to people, but learning English helped me connect with others and meet new people. I have changed a lot.”

    A motivation like Alice’s requires strong teacher support and peer motivation woven into structured learning. Alice can set her goals and with the GSE Learning Objectives map out what she needs to do to achieve them. Teacher encouragement and personal support – and easy access to digital coursework, a social community of others all learning English, and small classes that emphasise conversation – keep people like Alice engaged and motivated to achieve her language goals. “I cannot do it without them”, she says.

    2. Professional learners

    These learners are typically in a more formal type of English programme and are learning the language to achieve specific career milestones, such as a promotion. Their employer might even be paying for their learning or they might be reimbursed for the cost of their lessons.

    Vincenzo is 33 and works as a Product Manager in Milan for an international organization with offices around the world. He says: “I asked to take English classes as part of my professional development. My company chose an English provider and gave me a choice of group or one-to-one classes. I chose one-to-one classes as I’m easily distracted.”

    Professional learners like Vincenzo succeed using a blended learning model of learning in class and at home that they can tailor around their lives. They have a strong motivation to succeed – that’s why learning at home works for them – but step-by-step progress provided by the GSE Learning Objectives is also important to keep this motivation alive. “I met with my teacher once a week where we would work on mistakes I would make while speaking English. He would also give me extra practice materials, like interesting games and videos to listen to in my own time, to help me really get a better understanding of the language,” Vincenzo says.

    3. Academic learners

    Learning English is a requirement for many school programmes and students will continue this at college or university. Many of these students will be learning English with a formal course that offers practice tests for high-stakes exams.

    Seventeen-year-old Subra is from Malaysia and learns English at school. Some of her family live in Australia and she is considering studying abroad to attend a University that specializes in health care. When she was young, she learned in a traditional classroom backed with tests that helped her see how she was progressing. Now she uses technology, such as her Android Huawei phone to practise her English but still needs the validation of regular testing to know she is on track.

    Subrasays: “I am used to studying for tests as I prepared hard for exams to get into middle school and senior school, which was totally determined by test results.”

    Academic learners like Subra need to see demonstrable results to help them stay motivated and guide them to the level of English they need to achieve to get the required score on high-stakes tests. With the clear GSE Learning Objectives and a placement test, academic learners can map out where they are right now and where they need to be in order to reach their academic goals. These learners need encouragement and validation of their progress from their teachers to help keep them on track.

    Understanding student motivations will help you teach to their specific needs, thus helping them to stay focused and motivated in achieving their goals.
