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.

    International Certificate home testing: Benefits, rules and requirements

    By app Languages

    Education has embraced remote and hybrid learning – and it looks like it’s here to stay as a more accessible option for students everywhere. For the same reasons, even higher-stakes English exams are proving it’s possible to throw off old-fashioned approaches and adapt to the changing needs and expectations of today’s test-takers. The app English International Certificate is available online (as well as in paper-based format) and can be taken in a home environment. It has a number of benefits for both teachers and test takers.

    In this post, we will look at why testing from home is a good option and explore the rules and requirements for the online app English International Certificate.

    5 benefits of remote language testing

    1. Flexibility to take the test anywhere

    One of the great things about taking the online International Certificate is that test-takers can do it from any private location with a reliable internet connection.

    While we offer the option to take the test in one of our authorized computer-based testing centers, we now also offer testing from home with the . Both delivery methods are backed by the same level of robust security, meaning International Certificate test results can be equally trusted regardless of where the test was taken.

    2. Fits into learners’ schedules

    The online International Certificate allows test-takers to schedule their 2-hour test at a time that fits into their timetable and is not restricted by location. This means that they don’t have to take time off work or education to take the test, or suffer the additional stress or inconvenience this can cause to their lives.

    Using just one system and one log-in, they register for the test, schedule it for whenever suits them and then, when the time comes, sign in to gain access to the online proctoring system.

    3. Easy-to-use testing platform

    The International Certificate is available through , the online assessment portal that brings teachers, test-takers and tests together in a single, user-friendly space.

    Test Hub is extremely straightforward to use for scheduling, taking tests and accessing results – while also delivering powerful, data-rich insights into test performance for both teachers and test-takers.

    Furthermore, we have clear resources showing new users how to navigate the platform, as well as online videos on to help learners familiarize themselves with the online International Certificate format.

    Also available through Test Hub is the Readiness Test, which predicts readiness to pass the International Certificate, as well as the Level and Benchmark Tests – assessments that teachers find invaluable for placing new students in the right class and tracking their progress to proficiency.

    4. Quicker to mark and issue results

    All tests are scored using an AI system. This speeds up the turnaround time for results, making the whole process much more efficient than the paper-based exam.

    Governments trust app’s world-leading scoring technology, businesses and universities globally and is powered by the expert input of thousands of skilled, experienced English teachers. Since 2022, the online International Certificate has been scored entirely using this system, bringing the score turnaround time to under 2 weeks – a fraction of the time taken to score the paper-based test.

    5. Accessible to all

    Running an assessment online means that many people from around the world can access it. So, this will allow people in some of the world's most remote areas to get a recognized English certificate and change their lives, as long as they meet the following requirements.

    app English International Certificate requirements

    There are a that test-takers need to be aware of when taking the exam from home. These include:

    • a computer- test-takers must have access to a computer or laptop for the test duration. We recommend using a personal rather than a work computer as the testing software uses a secure browser that restricts other programs from running. Therefore, firewalls or network settings on work computers may cause problems.
    • a government-issued ID - To sign in to the online testing system, test-takers must have their government-issued ID, such as a passport, identification card or driving license, ready to present.
    • internet access - As the test requires continuous audio and video streaming, test-takers need to maintain a good internet connection. Additionally, we recommend connecting to a hardwire ethernet cable. Alternatively, test-takers should ask others at home to avoid using the internet during the exam.
    • a headset- Test-takers need a wired headset to take the test, rather than a Bluetooth one. This needs to include a microphone. Make sure it is of good sound quality so that tasks can be completed effectively.
    • a webcam - Test-takers need a webcam as they’ll be monitored by our online proctoring system throughout. This is to ensure that they do not have help from another person, or their notes nearby.
    • a private testing space - Test-takers must ensure they have a quiet and comfortable location that is completely private while doing the test. The proctor must end the session if anyone appears – even momentarily – during the test. The candidate is the only person allowed to see and answer the test questions.

    The International Certificate testing rules

    There are a number of simple, yet critical rules to follow when taking the International Certificate test from home. These include:

    • minors need adult consent - Test-takers who are under 18, an adult must be present to show their ID and provide consent. Then they must leave the room for the test to begin.
    • test taker must remain in webcam view - The test is under 2 hours with one optional 10-minute break. Aside from this break, people taking the test must not stand up or leave their workspace.
    • remove watches - Test-takers must remove all watches and smart watches to be stored out of sight.
    • store personal items away - Test-takers must store all their personal items out of reach during the test. They can not use phones, books, pens, notes or whiteboards.
    • clear exam workspace - There shouldn’t be any clutter on the desk or workspace. The proctor will check that no prohibited items are in the room before beginning.
    • no handwritten notes allowed - Test-takers are not permitted to take handwritten notes during the test. They may use the notes feature in their browser to take notes.

    Improve your English without saying a word

    By

    Communicating in English goes far beyond simply learning English vocabulary. In fact, there are many non-verbal strategies you can leverage to appear more confident as you improve your English. Below you’ll find three of the most important aspects of non-verbal communication to work on:

    Make eye contact when you speak in English

    When you’re talking to someone, it’s best to look them in the eye as much as possible. This shows that you are engaged in the conversation and listening intently when not speaking. Especially in loud environments, you may find your eyes drawn to someone’s lips as they talk. While it may help you better understand what they’re saying in a noisy place, like a restaurant, aim to maintain eye contact as much as you can (but do remember to take a quick break away once in a while so as to not stare too intently).

    Be mindful of body language

    What you’re doing with your hands and the facial expressions you make can say a lot—sometimes more than words! Not only should you be aware of the body language of who you’re talking with, but you also need to know what your body language is saying about you. Different cultures see hand gestures differently so it's good to be mindful of what gestures you make with your hands. If you want to appear open and friendly you may want to keep your arms open and avoid closed body language like crossing your arms.

    If someone is leaning away from you slightly, this may indicate they aren’t interested in the topic you’re speaking about. They may lean in closer if more interested in what you're talking about. If they smile a lot, this may mean they agree with you.

    Prepare yourself for English conversations you may have

    If you are planning to practice talking in English, it’s OK to prepare yourself for the conversation. Create a script for yourself to speak from that allows you to practice difficult terms and phrases. Not only will this give you real-time experience bettering your skills, but it will allow you to speak English with confidence.

    Either in work situations or casual conversations, there’s more than just English words being exchanged so remember to dedicate your full attention. It’s an excellent opportunity to practice and improve your English skills and you’re likely to learn more than just studying on your own.

    Computer-based language assessment: The future is here

    By David Booth

    Many people are surprised at the idea of a computer program marking an exam paper. However, computer-based testing already exists in many different formats and many different areas. Many tests or exams that form part of our daily life are taken on computers. If you’ve ever learned to drive, sat a citizenship test, done a training course at work, or completed a placement test for a language course, the odds are that you’ve already taken an automated test.

    Yet despite it being so common, there is still a lack of understanding when it comes to computer-based language assessment and how a computer can evaluate productive skills like speaking and writing.

    Computer-based testing: a closer look

    A common issue is that people have different ideas of what these tests entail. Computers can fulfill several essential roles in the testing process, but these often go unacknowledged. For example, a variety of test questions are needed to administer an exam, along with relevant data, and computers are used to store both the questions and the data. When it comes to creating randomized exams, computer software is used to select the exam questions, based on this data.

    Computers can make complex calculations far more quickly and accurately than humans. This means that processes that previously took a long time are completed in days, rather than weeks.

    Artificial intelligence (AI) technology is now capable of grading exam papers, for example. This means a shorter wait for exam results. In , candidates receive their results in an average of two days rather than waiting weeks for an examiner to mark their paper by hand.

    The benefits for students and teachers

    People take exams to prove their skills and abilities. Depending on their goals, the right result can open the door to many new opportunities, whether that is simply moving on to the next stage of a course, or something as life-changing as allowing you to take up your place on a university course in another country.

    A qualification can act as a passport to a better career or an enhanced education, and for that reason, it’s important that both students and teachers can have faith in their results.

    Computer programs have no inherent bias, which means that candidates can be confident that they will all be treated the same, regardless of their background, appearance or accent. , just one of app’s computer-based exams, offers students the chance to score additional points on the exam with innovative integrated test items.

    This integration means that the results are a far more accurate depiction of the candidate’s abilities and provide a truer reflection of their linguistic prowess.

    More than questions on a screen

    It’s not as easy as simply transferring the questions onto a computer screen. All that does is remove the need for pen and paper; this is a missed opportunity to harness the precision and speed of a computer, as well as its learning potential.

    Tests that have been fully digitized, such as PTE Academic, benefit from that automation; eliminating examiner bias, making the test fairer and calculating the results more quickly. Automated testing builds on the technological tradition of opening doors for the future – not closing them.

    How technology enhances language testing

    The development of automated testing technologies doesn’t merely make the examination process quicker and more accurate – it also gives us the chance to innovate. Speaking assessments are an excellent example of this.

    Previously, this part of a language exam involved an interview, led by an examiner, who asked questions and elicited answers. But now that we have the technological capability, using a computer offers students the chance to be tested on a much wider range of speaking skills, without worrying about the inherent bias of the examiner.

    Indeed, the use of a computer-based system facilitates integrated skills testing. Traditionally, language exams had separate papers focusing on the four skills of reading, listening, speaking and writing. But the more modern concept of language testing aims to assess these linguistic skills used together, just as they are in real-life situations.

    Afterwards, the various scores are categorized to allow learners an insight into their strengths and weaknesses, which helps both students and teachers identify areas which need improvement. This useful feedback is only possible because of the accuracy and detail of automated exam grading.

    The space race on paper

    Back in the 1960s, during the space race, computers were still a relatively new concept. Kathleen Johnson, one of the first African-American women to work for NASA as a scientist, was a mathematician with a reputation for doing incredibly complex manual calculations. Although computers had made the orbital calculations, the astronauts on the first space flight refused to fly until Kathleen had checked those calculations three times.

    This anecdote reminds us that - although computer technology is an inherent part of everyday life - now and then, we still need to check that their systems are working as they should. Human error still comes into play – after all, humans program these systems.

    PTE Academic – a fully digitized exam

    Every stage of PTE Academic, from registration to practice tests to results (both receiving and sharing them with institutions) happens online. It may come as a surprise to learn that the test itself is not taken online. Instead, students attend one of over 295 test centers to take the exam, which comes with the highest levels of data security.

    This means that each student can sit the exam in an environment designed for that purpose. It also allows the receiving institutions, such as universities and colleges, to be assured of the validity of the PTE Academic result.

    The future is here

    We created computers, but they have surpassed us in many areas – exam grading being a case in point. Computers can score more accurately and consistently than humans, and they don’t get tired late in the day, or become distracted by a candidate’s accent.

    The use of AI technology to grade student responses represents a giant leap forward in language testing, leading to fairer and more accurate student results. It also means more consistency in grading which benefits the institutions, such as universities, which rely on these scores to accurately reflect ability.

    And here at app, we are invested in staying at the cutting edge of assessment. Our test developers are incorporating AI solutions now, using its learning capacity to create algorithms and build programs that can assess speaking and writing skills accurately and quickly. We’re expanding the horizons of English language assessment for students, teachers and all the other professionals involved in each stage of the language learning journey.
