African schools gear up for the AI revolution


The emergence of cheap or free AI tools is being eagerly embraced by those with smartphones and the ability to get online. As governments and legislators struggle to get their heads around the implications of this powerful technology and work out how to bring in regulations for its safe use, millions of people are enjoying its ability to save time, helping them to transforming raw data into essays, exam answers, or, with a bit more work, even videos and podcasts.


Even in developing countries where electricity and internet access is limited (it’s estimated that over 570 million people in Africa lack electricity), there is enthusiasm for the potential of AI. In the Democratic Republic of the Congo (DRC), for example, a nation riven by internal conflict, poverty and vast inequality, educators are seeing the impact of AI. “It is obvious that our country is lagging behind in terms of new technologies for one reason or another,” says Benjamin Sivanzire, a teacher in Beni, North Kivu Province. “Many parts of the DRC do not even have traditional methods of communication, or even radio or television.” However, even though Mr. Sivanzire and his students are not yet able to make use of AI in their classes, they are seeing it being used in the wider culture, often in a negative way, to manipulate public opinion. The teacher underlines the importance of educating people to distinguish between verifiable information and lies. “There are videos created by artificial intelligence that show images that are not real and have been created for propaganda purposes,” he explains.


One concern that is frequently raised is the extent to which the development of AI tools is concentrated in the hands of a relatively small group of people. Farida Shahid, the independent Special Rapporteur on the right to education, shares these concerns. “AI algorithms are being made by individuals who often sit in a particular location, such as Silicon Valley, where the people who make and test them have their own biases,” she says. “Often the algorithms don’t do well at recognizing people with dark skin. They also have great problems with people who are autistic and don’t like looking into cameras. “Another example is the UK where, recently, an AI program was used to grade exam papers. This led to decisions that were biased against people from certain ethnic backgrounds. We really need to look at this issue more closely, starting with the human rights perspective, and I think that’s where the U.N. role comes in: if you increasingly rely on AI as the source of verification, you’re going to have problems because you are using a framework  which privileges white males, and doesn’t reflect the whole gamut of people’s lives and experiences”.


The urgent need to expand the developer talent base has been identified by the UN as central to ensuring that a wide variety of voices are heard in the “EdTech” (educational technology) space. Shafika Isaacs, the head of technology and AI at the UN agency for science, technology and education (UNESCO), says that the number of African EdTech startups has been mushrooming in recent years, with entrepreneurs experimenting with the AIenabled digital tools which could support learning and teaching across many different contexts, including in African languages, and local dialects. “I’ve personally engaged with a startup that matches high school students to career pathways, including choosing the right university, community college or even entrepreneurship program. They have seen strong results because of their focus on children in underprivileged contexts and schools. Tech startups have also looked at developing AI-enabled mobile apps, including chat bots, that can support teachers in teaching literacy or teaching mathematics. “The challenge is that there’s often a disconnect between the public education system and tech startups. We need educators to be proactive in engaging with those developing tools, and we encourage students and teachers to learn how to create and design technologies that are relevant to their linguistic and cultural contexts.”


Many African governments are keen to adopt national AI strategies and integrate AI into their national policies on technologies in education. In Côte d’Ivoire, where AI is already being widely used in the private sector, Mariatou Koné, the Minister of Education, says that the country’s education system is undergoing a transformation, following a 2022 review which recommended a digitalization strategy. “We have put in place initiatives to ensure that everyone is aware of the issue of AI. It can provide individual learning programs, and help struggling students to improve,” said Ms. Koné. “However, we are worried about potential abuses. We have to be able to protect personal data and ensure that learners are aware of the potential dangers.” The Minister agrees that, in order to guard against bias, the pool of engineers building AI tools needs to be expanded. “We need the right tools, adapted to the African context, to the Ivorian context. We have our own history, our own heritage. If we create our own industry, it has to be adapted to the realities of Côte d’Ivoire.”

During English class, a Brazilian student is reading the first paragraph of Text I. She stops and tells the teacher, “I’m confused. The text says governments want to ‘work out’ how to ‘bring in’ regulations. I know ‘work’ is a job and ‘out’ is the opposite of ‘in’, but it doesn’t make any sense.”


In that situation, the accurate response from the teacher is

An English teacher identified that a Brazilian student consistently misused the word "actually" as a direct translation of the Portuguese "atualmente," producing sentences such as "Actually, the unemployment rate has increased significantly," when intending to express the idea of "at the present time." The teacher clarified that "actually" is a false cognate meaning "in fact" or "in reality" — used to correct or emphasize information — and that the correct English adverb to convey the temporal meaning of "atualmente" is:

Defining the Role of a Tax Auditor


    The core function of a tax auditor is to examine financial records and supporting documentation against the figures reported on official returns, whether for individuals or corporations. This examination seeks to verify every line item, from gross receipts and reported income to specific deductions claimed for ordinary and necessary business expenses. A primary goal is to confirm that the taxpayer's stated liability aligns precisely with the relevant federal or state tax law.

   The auditor works to identify discrepancies or misapplications of the law that may lead to an underpayment of taxes due. They scrutinize documentation that supports deductions, such as receipts for depreciation claimed or substantiation for charitable contributions. The auditor ultimately determines if the taxpayer owes additional tax, is due a refund, or if the return is accurate as filed.

South-East Asian floods leave more than 1 million homeless across Indonesia and Sri Lanka

    Recent flooding and landslides across Indonesia, Sri Lanka and Thailand have caused severe devastation. More than 1,300 people have died, and over 1.2 million residents in Indonesia are displaced, many living in temporary shelters under difficult conditions.

    When rain began pelting villages on the Indonesian island of Sumatra, residents thought it could simply be another wet season storm. But then it got heavier and it did not stop for days. When floodwater began rising through their homes, the residents realised how much trouble they were in. Siti Nurbaya Siregar and her family had to scramble to the roof once the water rose to their ________________ necks.

"I was rescued by my neighbour on a tiny boat," the Langkat region resident said.

"It was loaded with my children, my mum, other relatives. Altogether, seven of us were on it.

"At one point the boat almost flipped over on the way to the rescue point." Half of the homes in her village were destroyed.

    Sri Lanka also reported more than 218,000 people in shelters, while rescue teams continue searching for missing residents.
    
   Governments in the region have promised reconstruction, but displaced communities continue to demand more immediate support such as food, shelter, and medical care.

Polysemy occurs when a single word has multiple related meanings depending on the context. Distinguishing these meanings is a key skill for advanced learners. Concerning polysemous words, mark T for True and F for False:


(__)The word 'bank' is polysemous because it can refer to a financial institution or the side of a river, and these meanings are historically related.


(__)In the sentence 'I can't bear the noise', the word 'bear' has a different meaning and grammatical category than in 'The polar bear is white'.


(__)Contextual clues such as collocations and the overall topic of the text are insufficient to determine the specific meaning of a polysemous word.


(__)A dictionary entry for a polysemous word typically lists all its related senses under a single heading, unlike homonyms which have separate entries.

Criminal forensics, also known as forensic science, is a field that applies scientific methods and technical knowledge to the investigation of crimes. Forensic experts analyze physical evidence collected from crime scenes, such as fingerprints, DNA, weapons, documents, and digital data. Their work aims to reconstruct events and provide reliable technical evidence to support the criminal justice system.
