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.

    8 first lesson problems for young learners

    By Joanna Wiseman

    The first class with a new group of young learners can be a nerve-wracking experience for teachers old and new. Many of us spend the night before thinking about how to make a positive start to the year, with a mixture of nerves, excitement, and a desire to get started. However, sometimes things don’t always go as expected, and it is important to set a few ground rules in those early lessons to ensure a positive classroom experience for all, throughout the academic year.

    Let’s look at a few common problems that can come up, and how best to deal with them at the start of the school year.

    1. Students are not ready to start the class

    How the first few minutes of the class are spent can greatly influence how the lesson goes. Students can be slow to get out their equipment and this can cause a lot of time wasting. To discourage this, start lessons with a timed challenge.

    1. Tell students what you want them to do when they come into class, e.g. sit down, take out their books and pencil cases, sit quietly ready for the lesson to start.
    2. Time how long it takes for everyone to do this and make a note. Each day do the same.
    3. Challenge students to do this faster every day. You could provide a goal and offer a prize at the end of the trimester if they reach it, e.g. be ready in less than a minute every day.

    2. Students speak their first language (L1) in class

    One of primary teachers' most common classroom management issues is getting them to speak English. However, young learners may need to speak their mother tongue occasionally, and a complete ban on L1 is often not the best solution. But how can we encourage students to use English wherever possible?

    Tell students they have to ask permission to speak in L1, if they really need to.

    • 3 word rule — tell students that they can use a maximum of three words in L1 if they don’t know them in English.
    • Write ENGLISH on the board in large letters. Each time someone speaks in L1, erase a letter. Tell students each letter represents time (e.g. 1 minute) to play a game or do another fun activity at the end of the lesson. If the whole word remains they can choose a game.

    3. Students don’t get on with each other

    It is only natural that students will want to sit with their friends, but it is important that students learn to work with different people. Most students will react reasonably if asked to work with someone new, but occasionally conflicts can arise. To help avoid uncomfortable situations, do team building activities, such as those below, at the beginning of the school year, and do them again whenever you feel that they would be beneficial:

    • Give students an icebreaker activity such as 'find a friend bingo' to help students find out more about each other.
    • Help students learn more about each other by finding out what they have in common.
    • Balloon race. Have two or more teams with an equal number of students stand in lines. Give each team a balloon to pass to the next student without using their hands. The first team to pass the balloon to the end of the line wins.
    • Team letter/word building. Call out a letter of the alphabet and have pairs of students form it with their bodies, lying on the floor. When students can do this easily, call out short words, e.g. cat, and have the pairs join up (e.g. three pairs = group of six) and form the letters to make the word.

    4. Students don’t know what to do

    When the instructions are given in English, there will inevitably be a few students who don’t understand what they have to do. It is essential to give clear, concise instructions and to model the activity before you ask students to start. To check students know what to do and clarify any problems:

    • Have one or more students demonstrate using an example.
    • Have one student explain the task in L1.
    • Monitor the task closely in the first few minutes and check individual students are on the right track.

    5. A student refuses to participate/do the task

    This is a frequent problem that can have many different causes. In the first few lessons, this may simply be shyness, but it is important to identify the cause early to devise an effective strategy. A few other causes might include:

    • Lack of language required to respond or do the task. Provide differentiation tasks or scaffolding to help students with a lower level complete the task or have them respond in a non-oral way.
    • Low self-confidence in their ability to speak English. Again, differentiation and scaffolding can help here. Have students work in small groups or pairs first, before being asked to speak in front of the whole class.
    • Lack of interest or engagement in the topic. If students aren’t interested, they won’t have anything to say. Adapt the topic or task, or just move on.
    • External issues e.g. a bad day, a fight with a friend, physical problems (tiredness/hunger/thirst). Talk to the student privately to find out if they are experiencing any problems. Allow them to 'pass' on a task if necessary, and give them something less challenging to do.

    It is important not to force students to do something they don’t want to do, as this will cause a negative atmosphere and can affect the whole class. Ultimately, if a student skips one or two tasks, it won’t affect their achievement in the long run.

    6. Students ask for repeated restroom/water breaks

    It only takes one student to ask to go to the restroom before the whole class suddenly needs to go! This can cause disruption and stops the flow of the lesson. To avoid this, make sure you have rules in place concerning restroom breaks:

    • Make sure students know to go to the restroom before the lesson.
    • Have students bring in their own water bottles. You can provide a space for them to keep their bottles (label them with student names) in the classroom and have students fill them daily at the drinking fountain or faucet.
    • Find out if anyone has any special requirements that may require going to the restroom.
    • Provide 'brain breaks' at strategic points in the lesson when you see students becoming restless.

    7. Students don’t have the required materials

    • Provide parents with a list of materials students will need on the first day.
    • If special materials are required in a lesson, give students a note to take home or post a message on the school platform several days before.
    • Don’t blame the student - whether they have a good reason or not for turning up to class empty-handed, making a child feel guilty will not help.
    • Write a note for parents explaining why bringing materials to class is important.

    8. Students are not listening/talking

    Getting their attention can be challenging if you have a boisterous class. Set up a signal you will use when you want them to pay attention to you. When they hear or see the signal, students should stop what they are doing and look at you. Some common signals are:

    • Raising your hand- When students see you raise your hand, they should raise their hands and stop talking. Wait until everyone is sitting in silence with their hands raised. This works well with older children and teenagers.
    • Call and response attention-getters - These are short phrases that prompt students to respond in a certain way, for example: Teacher: "1 2 3, eyes on me!"Students: "1 2 3, eyes on you!". Introduce a new attention-getter every few weeks to keep it fun. You can even have your students think up their own phrases to use.
    • Countdowns -Tell students what you want them to do and count backwards from ten to zero, e.g. "When I get to zero, I need you all to be quiet and look at me. 10, 9, 8 …"
    • Keep your voice low and speak calmly -This will encourage students to stop talking and bring down excitement levels.
    • A short song or clapping rhythm -With younger children, it is effective to use music or songs for transitions between lesson stages so they know what to do at each stage. For primary-aged children, clap out a rhythm and have them repeat it. Start with a simple rhythm, then gradually make it longer, faster, or more complex.
