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.”
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.

It's incredible to know that there are thousands of languages spoken across the world, each with its unique set of challenges for learners. A question that often pops up is: "Which language is the hardest to learn?". Today we take a closer look at this question and consider different factors that make learning a language challenging.
Preparing students for the modern world of work can be challenging; it's constantly adapting and changing which can be hard to keep track of. Today's post is a Q&A on the teaching of employability skills and the essential skills and qualities students need to thrive in the 21st century. offers insights to answer common questions and help you improve your language teaching skills.
My advice is to push the issue back to the students by putting them in groups and asking each group to identify a different job/career that involves people working with others. Then ask "What would happen if this job was competitiveinstead of collaborative?" You may have to re-explain the concepts, but let students write a little story about a situation in which the workers suddenly all turn competitive.
For example, It was chaos in the women's soccer/football game. All the members of the blue team suddenly became competitive. Each one still wanted to win, but each decided that she would shoot a ball into the other team's net. This included the goalie, who ran up to the front of the field and purposely shoved and tripped members of her team ….
Or for more traditional jobs, In the middle of the operation the nurse pushed the doctor out of the way and picked up the instrument. The patient also wasn’t completely asleep, and he tried to do the operation himself, then …
It's all absurd, of course, but it can lead into other tasks asking students why collaboration is so important in each job. Then, turning it back to language, what kinds of language does each profession require to collaborate? For soccer/football players, this includes shouted requests and commands:Pass the ball to me! Shoot!as well as hand and body gestures. Similarly, doctors require professional jargon:Pass me the scalpel, please.Rather thanGive me the pointy knife thing!
One hundred years ago, in 1923, Thomas Edison predicted that motion pictures would replace teachers and books. Since then, similar predictions have been made for radio, TV and computers. It hasn't happened, and one of the reasons is that we crave the human touch in our teaching and learning. I recently read. "When it comes to getting knowledge to stick, there may be no substitute for human relationships. … I've been to former students' weddings and baby showers and funerals of their parents," says Millard, the high school English teacher in Michigan. "I've hugged my students. I've high-fived my students. I've cried with my students. A computer will never do that. Ever, ever.”(Waxman, 2023, para. 21-22)
But, that doesn’t mean teachers should stop learning about new technologies. We need to keep finding ways for them to help us and our language learners in the classroom. It can seem overwhelming, though, which is why I recommend shifting responsibility to students: “Do any of you know about ChatGPT? Yes? How do you think you could use it to help you learn?”
Although the world is in many ways competitive, there are countless examples of how students will do better by collaborating. Most of our students today won't be working in environments where they are competing against their co-workers. Instead, they'll be in teams and need critical thinking and negotiation skills to help them do so.
One way forward is to ensure that your classroom features more collaborative activities. Get students working in pairs and groups on all their assignments, but also create a buddy system so students always have someone else to ask for help. For example, if they're having to read a text and come across difficulties, it's often easier for them to text or call a friend than to wait until the next class. After a few collaborative activities, discuss collaboration versus competition with students and ask them which they prefer. Also, ask them for examples of what their friends and family members do regarding collaborating and competing.
As always, it's better to lead students to understand a new idea than to tell them.

Reflective teaching, despite it sounding modern and sophisticated, has not yet become a common practice among English language teachers. However, the experientialproposed byoffers a practical approach for teachers. The cycle involves teaching a lesson, reflecting on "what we did" and "how we did them," and then using that reflection to improve future English classes. By using this approach, teachers can prepare for better teaching in the long term.
