SINGAPORE – Depression in people above the age of 60 is associated with an increased risk of dementia, and may sometimes be an early sign of cognitive decline.

Now, emerging research has highlighted a significant link between depression diagnosed in young and middle-aged adults and an increased risk of dementia later on.

A 2023 study published in US-based medical journal Jama Neurology analysed data from over 1.4 million Danish citizens and identified whether they had been diagnosed with depression. They were then followed from 1997 to 2018 to see who developed dementia later in life.

Those diagnosed with depression, including young and middle-aged adults aged 18 to 59, were more than twice as likely to be diagnosed with dementia later in life compared with those without depression. This is according to an analysis by researchers at the Perelman School of Medicine at the University of Pennsylvania and Aarhus University in Denmark.

The link highlights the importance of addressing mental health to protect long-term brain function.

Depression and dementia are common conditions in Singapore.

According to the SingHealth website, an estimated 5.8 per cent of the population suffer from depression. And Singaporeans deemed mental health as the biggest health problem the country faced in 2023, above cancer and stress, according to the World Mental Health Day 2023 report by market research firm Ipsos.

Dementia advocate Emily Ong says with growing awareness and emphasis on mental health and well-being, it is crucial to explore the potential long-term impacts on cognitive health in Singapore’s ageing population. 

According to the Institute of Mental Health’s Well-being of the Singapore Elderly study released on Aug 28, the number of seniors with dementia rose from 51,934 in 2013 to 73,918 in 2023 – because of an increase in the adult population here.

But the prevalence of dementia among older adults aged 60 and above here had dropped to 8.8 per cent, down from 10 per cent in 2013.

The study also found that those with a history of depression – it did not state how old they were – were nearly three times more likely to have dementia.

Ms Ong, who was diagnosed with young-onset dementia when she was 50, has seen young and middle-aged adults with depressive symptoms who develop dementia later in life.

Her relative, for instance, was diagnosed with depression in her 30s and is starting to experience cognitive decline like memory issues and reduced alertness. Ms Ong’s relative is in her 50s now and still taking medication for depression.

Dr Seng Kok Han, a consultant psychiatrist at Nobel Psychological Wellness Centre, frequently sees patients who have both depression and dementia.

For example, his patient, Mr A, was diagnosed with depression in his late 40s and has been battling chronic depression for many years. He struggled to stay consistent with his antidepressant medication and follow-up care.

By the time he reached his early 70s, Mr A started experiencing cognitive difficulties, such as forgetting appointments and having trouble with daily tasks. He was eventually diagnosed with dementia.

“Even after stabilising his depression, his cognitive deficits persisted. In his case, the long history of untreated or poorly managed depression likely played a significant role in his cognitive decline,” says Dr Seng.

What do dementia and depression have in common?

Dementia is a general term for the ongoing decline of cognitive functioning to an extent that it interferes with a person’s daily life and activities. Depression is a mood disorder that causes a persistent feeling of sadness and loss of interest. It affects how you feel, think and behave, and can lead to emotional and physical problems.

Dr Annabelle Chow, principal clinical psychologist at Annabelle Psychology, says there has been evidence in recent years which show that depression in early adulthood is associated with an increased risk of dementia.

However, the mechanisms involved are complex, she says, with no single process being able to fully explain this connection.

It is clear, however, that both depression and dementia cause increased neurodegeneration and reduced neuronal repair, says Dr Chow.

This means that in both conditions, there is a faster or greater loss of brain cells, leading to a decline in brain function over time, and the brain’s ability to fix or heal its nerve cells is weakened or slowed down.

Chronic depression can speed up changes in the brain that may lead to dementia through at least two physical processes, says Dr Chow.

The first involves changes in blood vessels in the brain, mainly in the form of a condition called leukoaraiosis, which damages the brain’s white matter. This has been identified as a risk factor for dementia, she notes.

The other is through excessive release of cortisol, a stress hormone which, in turn, damages the hippocampus – a part of the brain that is crucial for forming and storing memories.

“Chronic elevation of cortisol can damage brain structures that are important for memory and cognitive function. This can lead to the shrinking in brain structure and function, including reduced hippocampal volume, and contribute to a person developing dementia later in life,” says Dr Chow. 

​In addition, depression can result in a person isolating ​himself or herself. The reduced activity or interaction increases the risk of developing dementia, says Dr Chow.

In her practice, she does see adults with depression who are concerned about their cognitive function.

Certain subtypes of depression in particular, like vascular depression, have been linked to an increased risk of developing dementia, says Dr Seng.

“This association is thought to arise because both conditions share common vascular risk factors, such as hypertension, diabetes and atherosclerosis (build-up of fats, cholesterol and other substances in and on the artery walls). These risk factors can lead to reduced blood flow and damage to brain tissues, which contribute to cognitive decline and the development of dementia​,” he adds.

Vascular depression is a type of depression in older adults, typically over the age of 60. It is associated with reduced blood flow and vascular changes in the brain, such as small vessel disease, which can impair mood regulation.

Studies have also shown that people who experience recurrent or severe depression are at higher risk of developing dementia.

Dr Chow says this relationship may be explained by research related to the brain, which suggests that prolonged depression can lead to damage in the hippocampus.

“Over time, this damage, along with the cognitive impairments associated with chronic depression, like reduced concentration and slowed thinking, may contribute to the development of dementia,” she says.

Depression, even in its milder forms, has been linked to an increased risk of developing dementia.

“Even subsyndromal depression, which refers to the presence of depressive symptoms that do not meet the full criteria for a depressive disorder, can increase the risk of dementia,” adds Dr Chow.

Distinguishing depression and dementia symptoms

Identifying whether depressive symptoms might be related to dementia can be challenging because the symptoms of both conditions often overlap, says Dr Sanveen Kang, clinical psychologist and founder at Psych Connect. 

However, there are some signs which may differentiate the two.

In depression, cognitive issues such as memory problems, difficulty concentrating and decision-making difficulties are often reversible with appropriate treatment, says Dr Kang.

However, cognitive decline in dementia is progressive and typically irreversible.

“People with dementia may not recognise or be aware of their cognitive deficits, and they might fill in memory gaps with fabricated or distorted information, rather than express concern,” notes Dr Kang.

Those with depression typically respond well to antidepressant medications together with psychotherapy, and a person’s cognitive symptoms may improve significantly once the depression is treated, she says.

However, if the depression is brought on by dementia, a person’s mood symptoms may get better with treatment, but his or her cognitive decline will continue to progress, adds Dr Kang.

A lack of improvement in cognitive function despite successful treatment of depressive symptoms could indicate underlying dementia, she says.

Early treatment for depression can reduce risk of cognitive decline

Depression can increase the risk of cognitive decline, but addressing it promptly can reduce this risk, notes Dr Seng.

“As depression is associated with increased inflammation, which can contribute to brain changes linked to dementia, treating the condition may reduce inflammation, potentially lowering the risk of dementia,” says Dr Kang.

In addition, certain antidepressant medications, like selective serotonin reuptake inhibitors, may help protect against brain changes associated with depression and dementia, she adds.

Some studies suggest that these medications can improve neuroplasticity and reduce hippocampal atrophy, which are crucial for cognitive function, notes Dr Kang.

Seeking help for depression is a sign of strength, not weakness, says Dr Seng.

“Your general practitioner can be an excellent first point of contact. He or she can assess your symptoms and refer you to a psychiatrist, psychologist or counsellor if needed,” he adds.

Ms Ong, who is a board member of Alzheimer’s Disease International, says: “We need to continually create a culture that talks about mental health. Mental health and brain health are very important, but there is a lack of awareness of their links.”

At least $28k lost through phishing scam involving fake OneMotoring website


At least $28k lost through phishing scam involving fake OneMotoring website

Victims received e-mails from a sender pretending to be OneMotoring by LTA, informing them that their vehicles’ road tax or road licence was expiring PHOTOS: SINGAPORE POLICE FORCE

SINGAPORE - At least eight victims have fallen for a phishing scam involving a fake local motoring website in September, the police said on Sept 17.

The victims lost at least $28,000 in total after they were led to the fake website where they keyed in their personal details.

They received e-mails from a sender pretending to be OneMotoring by the Land Transport Authority (LTA), informing them that their vehicles’ road tax or road licence was expiring, the police said.

The victims were then directed to a website that masqueraded as the OneMotoring portal, where they keyed in their vehicle registration numbers, personal information and credit and debit card details. They realised they had been scammed only when they saw unauthorised transactions made on their accounts.

The police said LTA does not inform vehicle owners of expiring road tax via e-mails, and their correspondences will not contain payment links. Instead, they do so via text messages sent from “gov.sg”, e-letters in users’ OneMotoring accounts or hardcopy letters sent to their place of residence.

The public are advised to take steps to avoid falling for scams, including downloading the ScamShield app and setting up security features, such as multi-factor authentication for bank accounts and e-wallets. If a site looks suspicious, one can check for signs of scams by calling the Anti-Scam Helpline on 1800-722-6688 or visiting www.scamalert.sg. Any fraudulent transactions should also be reported to the bank immediately.

Those with information on such crimes may also call the police hotline on 1800-255-0000, or submit it online at www.police.gov.sg/i-witness

SINGAPORE – At least nine cases of malware scams were reported since Aug 30, with total losses amounting to about $223,000.

The victims fell for the emerging variant of the malware scam by responding to fraudulent Facebook advertisements of food items, said the police on Sept 17.

Scammers would instruct the victims to share their devices’ screen and disable “Google Play Protect”– a function that lets users check apps and devices for harmful behaviour and run a safety check on apps from Google Play Store before they download them.

Under the pretext of an order number or receipt, victims are then instructed to download an Android package kit (APK) file containing malware through malicious links.

An APK is an app solely for Android users. Once downloaded, the malicious APK allows scammers to access and take control of victims’ devices remotely.

Victims would later find unauthorised transactions on their banking accounts.

Once the transactions are discovered, scammers would, in some cases, pose as bank officers and call the victims to convince them not to lodge police reports, claiming they would do so on their behalf.

Scammers posing as officers from law enforcement agencies, such as Interpol, may also call them and claim that the victims were involved in money laundering and ask for more money.

The police have asked people to be cautious when dealing with online ads, especially those on Facebook.

Applications should be downloaded from official app stores, and the developer information on the app listing, as well as the number of downloads and user reviews, should be checked to ensure their legitimacy.

Suspicious content or ads should be reported to Facebook, the police said. The number advertised on the ad should also be blocked on WhatsApp.

Any unauthorised transactions should also be reported to the bank immediately.

Those who suspect that their phones might have been infected with malware should switch the device to flight mode, said the police. They should also run an antivirus scan, check for unauthorised transactions on other devices or consider a factory reset of the phone, while also changing important passwords.

A factory reset restores a smartphone or computer back to its original state, and includes deleting all data, apps and settings on the device.

Members of the public with information relating to such crimes or who are in doubt are urged to call the police hotline on 1800-255-0000 or submit it online at www.police.gov.sg/iwitness.

想当年,我上高中时上英语课时,美女英语老师突然口吐白沫,晕倒在了讲台上。这时同学们都慌了,连忙问,怎么回事?怎么回事。此时,作为班长的我立马站了出来。我安排两个同学去报告校长;两个学生去办公室打120(当时我们都没手机)。然后我让同学们把老师抬到外面走廊上。继而我对她进行了人工呼吸。30:2,我时刻牢记。就这样大约过了十几分钟,老师醒了。她一看衣领被解开了,连忙问怎么回事。这时我们才慢慢的向她解释。后来,此事被她上报给了学校。后来学校在一次急救知识培训时,把我这事当做经典案例向同学们分享

为什么每个人都须学习AI技能

======

“智慧的AI使用者”可能不了解AI的技术细节或如何熟练编程。然而,他们拥有足够的知识,能够有效地利用这项技术,提高工作效率。

人工智能(AI)预计将重新定义未来的工作方式,因此人们须要熟练掌握这项技术。长期以来,许多人认为AI本质上是一种专门技术,用于执行非常特定的任务。例如:放射科医生就使用AI帮助分析X光影像,以评估患者的医疗状况,但AI只用于这一项工作。然而,2022年底发布的一个能够处理多项任务的AI聊天机器人,改变了游戏规则。

ChatGPT向世界展示了AI有潜力像电脑和智能手机一样,成为一种通用技术。这意味随着技术的发展和普及,每个人都可能在多个领域,把AI用于不同目的,并从中受益。即使现在,ChatGPT也可以帮助办公室工作人员和学生起草报告,帮助电脑程序员编写、检查并修复程序漏洞,帮助艺术家生成概念设计等等。

随着AI越来越多地影响我们生活的方方面面,拥有AI技能将成为未来10年求职的先决条件,就像在15到20年前电脑技能是求职的必要技能一样。

事实上,今年1月,国际货币基金组织指出,AI将影响全球近40%的工作岗位,这表明每个人都应该在某种程度上学习AI技能,以免落后掉队。

但并不是每个人都必须成为AI专家,并了解如何编程。就像电脑技能一样,未来所需的AI专业水平将根据个人的角色和工作而有所不同。

认识AI的局限性,为未来编程
有两个主要群体值得关注。第一组是“智慧的AI使用者”。他们可能不了解AI的技术细节或如何熟练编程。然而,他们拥有足够的知识,能够有效利用这项技术,提高工作效率。例如,工作人员通过编写提示问题,让ChatGPT飞速完成多份报告的总结和撰写,这比亲自动手写节省非常多时间。同时,他们非常清晰知道聊天机器人的局限在哪里,如聊天机器人可能不知道一个摘要报告对哪些国家有更高的关联度。

这种对AI输出结果进行辨别和评估的质量控制至关重要。因为AI是在不完美、不完整甚至错误数据上训练的。因此,正如许多过去的报告所指出的,AI的输出结果有可能是错误的。

因此,智慧的AI使用者必须能够识别AI响应中的缺陷,并知道如何对这些缺陷进行验证。如果错误的答案被用于关键任务的决策,结果可能是灾难性的。

第二组是“AI生产者”,他们拥有专业技能知识,能够编写代码,创建AI程序。想想那些创造了ChatGPT和SEA-LION(东南亚语言一体网络)的工程师。SEA-LION是一个新加坡制造的AI聊天机器人,使用来自东南亚的全面数据,并针对该地区的文化和语言进行定制的聊天机器人。

那些更具技术天份的人会钻研更深层次的专业技能,成为AI技术前沿的专家,引领AI科技的发展趋势。他们拥有博士学位,包括大学教授、研究人员和顶尖工程师。

人们如何通过学习技能成为智慧的AI使用者和生产者?一种方式是通过高等技能教育,另一个是对成人进行持续教育与培训(CET)。

首先,接受高等技能教育的学生可以在不必进行大量编程的情况下,开发对AI的基本理解和熟练运用。这可以使他们能够了解AI能做什么,并知晓如何在他们感兴趣的领域使用它。

随着编程变得越来越简化,无须高级编码技能即可创建基本的AI,了解AI的基本知识就变得非常必要。

认识到帮助学生为AI驱动的世界做好准备的必要性,新加坡南洋理工大学最近推出一门对所有本科生开放的AI辅修课程,帮助学生成为智慧的AI使用者。

学生将学习AI和数据科学如何跨不同专业领域解决问题。他们可以通过选择与他们的专业或兴趣一致的跨学科选修课,来定制这门辅修课程。

南大还推出一个新的“AI与社会”的学士学位课程,培养能够开发以人为本的解决方案的AI生产者。它专注于培养学生的深厚技术专长,同时辅以对AI可能被滥用的理解。学生还将有机会为他们热衷的领域和行业开发AI解决方案。

我们还需要一群非常有才华的AI生产者,他们必须能够编写复杂的代码,并且可以非常快速地创建成功的AI解决方案,来应对我们面对的各种挑战。为了培养这些AI生产者中的“突击队员”,南大设有一个新的“图灵AI学者计划”。

对于已经在职场的人来说,持续教育与培训的AI课程可以帮助他们适应AI带来的职场变化,学习相关的职业技能,提高生产效率。这些技能还可以帮助他们找到与AI相关的新职业。

为迈向AI世界去适应、学习和教学
我们鼓励更多人学习AI技能,同时,我们也必须考虑AI将如何影响学习本身。由于AI可以将世界上所有知识置于人们的指尖,特别容易获取,因此,我们可能很自然地会问:是否还有学习的必要性?其实,学习的必要永远存在。我们之所以能执行日常任务,是因为获得了能够理解这个世界不同方面的知识。没有知识,我们将无法理解周遭发生的事情;同理,没有知识,我们也无法理解AI输出的结果,无法判断这种结果的好坏。

要理解这一点,一个好例子就是将AI比作全球定位系统(GPS)的应用。如果我们不加思考,盲目地跟随GPS应用的指示,可能就无法辨别这个GPS应用是否会将我们带到一个有着同样名字,但却是错误目的地的地方。

这个例子说明,即使AI已经拥有信息,我们仍然须要具备坚实的、与工作相关的知识基础。只有这样,才能检验AI输出的结果,才能进行AI无法做到的、更有创造性和增值性的工作。

另一个问题是,如果我们停止获取知识,对创造力是一种巨大伤害。创造力是由知识激发的——没有它,我们将无法发展出新的想法和发现新的事物。

因此,在AI无处不在的世界中,提高知识以增强创造力将变得更加重要。

在AI世界,教师如何教学也须要重新审视。理想状态下,我们希望教育能够为每个学生量身定制,每个学生都可以有一个老师。然而,资源和时间的限制使这种要求变得不现实,我们通常只能有一个教师来教一整个班级。

但是,有了AI,一对一的教学就成为可能。一个由AI驱动的在线课程,可以同时适应班级中每个学生的学习节奏和能力。例如,如果AI可以实时评估哪些学生有更高水平的理解力和接受度,就可以向这些学生提供更高层次的课程。

AI还可以根据学生学习风格的偏好,调整它呈现给学生的课程模式。例如,对偏好视觉的学生,可以用更多图形进行教学;对偏好听觉的学生,则让他们接受更多基于音频的课程。

AI的个性化学习也可以帮助学生识别知识上的空白点,并推荐相应课程来填补这些空白。这意味着教师可以专注于教授学生新技能和知识,特别是那些AI不太擅长的新技能和知识。

AI还可以帮助教师预测学生是否可能在学习成绩上落后,以便及时提供帮助。AI还可以根据学生过去的学术记录,以及过去学生群体的记录,来预测学生的学习表现。

自2020年以来,南大一直在使用这样的AI工具,帮助负责学生事务的老师们在每个学期开始时,识别出在完成学业上可能会面临挑战的学生。有了这个工具,这些老师现在可以更多地关注帮助这些被识别的学生,为他们提供更多支持,帮助他们顺利完成学业。

在学生可以用ChatGPT这样的AI工具即时生成答案,并帮助他们写出论文时,教师须要考虑的另一个问题是我们应该如何评估学生。

与其要求学生对一个问题写出答案,不如要求学生使用ChatGPT去搜寻答案,并对聊天机器人给出的答案进行评估,对如何改进答案的质量进行建议。

随着AI逐渐改变这个世界,我们希望这一技术能够提升每个人,而不仅仅是特定的人群。为了做到这一点,每个人都须要在某种程度上学习AI技能,以认识AI的力量并充分地利用好AI。只有这样,我们才能敞开心扉,拥抱AI可能带来的无限可能性,并充分收获其可以带来的美好硕果。

Why everyone needs to learn AI skills

Why everyone needs to learn AI skills

Learning and creativity are more important than ever, even as AI skills become an increasingly essential requirement for many jobs in the coming decade.

By Professor Ho Teck Hua,

President, Nanyang Technological University, Singapore

AI is expected to redefine how people work in the future, so they will need to be competent in the technology. For a long time, many people believed that AI was essentially a specialised technology used to perform very specific tasks.

Case in point: Radiologists use AI to help analyse X-ray scans to assess a patient's medical condition, but AI can only be used for this one job. However, an AI chatbot released in late 2022 that can tackle multiple tasks, changed the game.

ChatGPT showed the world that AI has the potential to become a general-purpose technology, as has happened with computers and smartphones. This suggests that everyone can potentially use and benefit from AI for different purposes across a range of areas as the technology evolves and becomes more pervasive. Even now, ChatGPT can help office workers and students draft reports, computer programmers write and debug code, artists generate design concepts, and more.

As AI affects more and more facets of our lives, having AI skills will become a prerequisite for a job in the next decade, just like how computer skills were a requirement for jobs 15 to 20 years ago.

In fact, in January this year, the International Monetary Fund said that AI will affect almost 40 percent of jobs globally, suggesting that everyone should learn AI skills at some level to avoid being left behind.

Butnoteverybody has to be an AI expert and know programming. Just as with computer skills, the level of AI expertise required in the future will vary depending on one's role and job.

Recognising AI's limits, coding for the future

There are two main groups of people of interest. The first consists of "smart AI users". They may not know the technicalities of AI or how to code proficiently. However, they have enough knowledge to make the most of the technology and use it effectively to become more productive in their work. Take, for instance, workers who frame prompts to use ChatGPT to help them summarise multiple reports in a much shorter time than if they were to summarise the reports themselves. At the same time, they are keenly aware of the chatbot's limitations, such as how a summary might be more relevant to certain countries than others.

This quality control in discerning and assessing AI's output is crucial. The problem is that AI is trained on imperfect, incomplete and even incorrect data. As a result, AI's output can be wrong, as many past reports have pointed out.

So, smart AI users must be able to recognise flaws in AI responses and know that they need to be verified. If wrong answers are used to inform mission-critical decisions, the results could be disastrous.

The second group comprises "AI producers" who have the technical know-how and can write code to create AI programs. Think of the engineers who created ChatGPT and SEA-LION (Southeast Asian Languages In One Network), a Singapore-made AI chatbot that uses comprehensive data from Southeast Asia and is customised to the region's culture and languages.

Those who are even more technically inclined can develop a higher tier of skills and become AI experts at the frontiers of the technology to guide its future development. They have PhD degrees and include academic professors, researchers and top engineers.

How can people learn skills to become smart users and producers of AI? One way is through tertiary education, such as for undergraduate students, and continuing education and training (CET) for adult learners.

To start with, tertiary students can develop a fundamental understanding of AI and proficiency without having to do a lot of coding. This allows them to appreciate what AI can do and understand how to use it in their areas of interest.

Such knowledge is relevant as coding has become much simpler over time without the need for high-level coding skills to create basic AI.

Recognising the need to help students be ready for an AI-driven world, Nanyang Technological University, Singapore (NTU Singapore) recently introduced a Minor in AI programme that all NTU undergraduates can choose to take to become smart AI users.

Students will learn how AI and data science can solve problems across different fields. They can tailor the minor by selecting interdisciplinary electives aligned with their majors or interests.

NTU also launched a new Bachelor of Science in AI and Society degree program to nurture AI producers who can develop real-world solutions that put people at the heart of AI. It focuses on cultivating deep technical expertise among students while complementing that with an understanding of how AI could be misused. Students will also have the opportunity to develop AI solutions for domains and industries they are passionate about.

We will also need a group of exceptionally talented AI producers who can write sophisticated code well and do so very quickly to create successful AI solutions for the challenges we face. To groom these "commandos" among AI producers, NTU has a new Turing AI Scholars Programme.

For people already in the workforce, CET courses in AI can help them become more productive as they learn relevant skills to adapt to changes in their jobs brought about by AI. The skills can assist them in pivoting to new AI careers as well.

Adapting, learning and teaching to an AI world

Even as we encourage more people to learn AI skills, we need to consider how AI will affect learning too. As AI can put the world's knowledge at people's fingertips, it is natural to ask whether there is still a need to learn at all. But there will always be a need to learn. We are able to carry out our day-to-day tasks because we have acquired knowledge that allows us to understand various aspects of the world.

Without knowledge, we will not be able to comprehend what is happening around us and, by the same token, be unable to make sense of AI's output and judge whether it is good or bad.

One way to understand this is to liken AI to a global positioning system (GPS) app. If we blindly follow the app's directions without thinking, we may fail to realise if the app is taking us to a wrong destination that may have the same name as the place we want to reach, for example.

The implications are that we need to have strong foundations in knowledge that is relevant to what we do, even if AI already has the information. This will allow us to not only check AI's output but also have the basics to perform more creative, value-added work that AI is incapable of doing.

Another problem is if we stop acquiring knowledge; this is detrimental to creativity. Creativity is stimulated by knowledge – without it, we will not be able to develop new ideas and discover new things.

So, in a world where AI is pervasive, improving one's knowledge to boost creativity will be important.

In an AI world, how educators teach also needs to be reconsidered. Ideally, we want lessons to be customised to each student, with one teacher per student. However, resource and time constraints make this difficult, and we often have one educator teaching the entire class.

With AI, one-to-one learning is possible. An AI-powered online lesson can simultaneously adapt to the pace and aptitude of each student in a class. For example, if the AI assesses in real-time that a student has a higher level of understanding, more advanced lessons can be delivered to the student.

AI can also adjust the format of the lessons it presents to students based on their preferred learning style. For example, visual learners can be taught with more graphics, while auditory learners receive more audio-based lessons.

Personalised learning through AI can also help students identify gaps in their knowledge and recommend relevant lessons to bridge these gaps. What this means is that educators are freed up to focus on teaching students new skills and knowledge, especially those that AI is not as good at.

AI can also help educators predict whether students might be falling behind in their grades so that help can be rendered to them early. AI can predict a student's performance based on their past academic record as well as the records of students from past cohorts.

Since 2020, NTU has been using such an AI tool to help our student care managers identify at the start of each semester, students at risk of struggling academically. With this tool, managers can now pay more attention to helping identified students by providing them support and assistance to succeed in their studies.

Another issue that educators need to consider is how students should be assessed if they can easily access AI tools like ChatGPT to generate answers on the fly and help them write assignment essays.

Instead of asking a student to produce an answer to a question, teachers can ask students to use ChatGPT to find the answer, critique the chatbot's replies and suggest how the answers can be improved.

With AI poised to change the world, we want the technology to uplift everybody and not just select groups of people. To do so, everyone needs to learn AI skills at some level to appreciate the power of AI and be able to harness it. Only then can we open our minds to the possibilities that AI can bring and fully reap its benefits.
