A recent Executive Order by President Biden emphasized the link between racial equity, education, and artificial intelligence (AI). It stated that the Federal Government must both pursue educational equity and eliminate bias in the design and use of new technologies, such as AI.
The U.S. Department of Education’s report Advancing Digital Equity for All defines digital equity as the condition in which individuals and technological communities capacity needed have the for full participation in society and the economy.
Concerns about racial equity and bias are central to the debate on AI in education. AI systems rely on datasets, and when these datasets are non-representative or contain biased patterns, the resulting models may behave unfairly. Such systematic unfairness in automated decisions is known as algorithmic bias, which can lead to discrimination and undermine equity at scale.
Bias is intrinsic to how AI algorithms are trained on historical data. When these biases sustain unjust or discriminatory practices in education, they must be identified and addressed. For instance, algorithms used for admissions, early intervention, or exam monitoring should be regularly evaluated for evidence of unfair bias, not only during design but also as they are deployed in real educational contexts.

Smatphones are banned in Brazilian Schools
Brazil’s president has signed a law to limit smartphone use in schools, starting in February. This rule will apply to elementary and high schools across the country. Phones will only be allowed in emergencies, for educational activities, or for students with disabilities. The goal is to help students focus better and reduce distractions caused by phones.
Officials explained that children are using the internet at younger ages, which makes it harder for parents to monitor them. Limiting smartphones at school can help students concentrate on studying. A recent survey found that nearly two-thirds of Brazilians support banning smartphones in schools, and over threequarters believe these devices are harmful for kids.
Some families and students agree with the move, saying it will encourage more interaction and help classmates focus better. However, others believe it won’t solve all school issues, like bullying and harassment.
As of 2023, about two-thirds of Brazilian schools already limit smartphone use, while 28% ban them completely. Some states, such as Rio de Janeiro and Goias, have passed local laws restricting phones in schools, but enforcement has been challenging. In Sao Paulo, discussions are ongoing about banning phones in both public and private schools.
Globally, concerns ______________ smartphone use ______________ children have led to similar measures. Countries ______________ China, France, and parts of the U.S. have introduced restrictions to reduce distractions and protect children’s mental health. A report ______________ UNESCO found that one in four countries has already limited smartphone use in schools.

New generation of Indigenous activists battle to save the Amazon
Campaigners in Brazil use drones to document work of self-defence teams trying to stop environmental destruction caused by illegal mining
Batista, who belongs to South America's Macuxi people, is part of a new generation of Indigenous journalists helping chronicle an age-old battle against outside aggression. For centuries, non-Indigenous writers and reporters have flocked to the rainforest region to tell their version of that ancestral fight for survival. Now, a growing cohort of Indigenous communicators are telling their own stories, providing first-hand dispatches from some of the Amazon's most inaccessible and under-reported corners.
"It's dangerous work and we suffer a lot when we're out in the field," said Batista, one of about 26,000 inhabitants of Raposa Serra do Sol, Brazil's second most populous Indigenous territory. "But it really gives me strength because I'm showing the reality of our lives to the world."
"It's my job to monitor the territory: to see who's coming in and who is leaving, to find areas being invaded, and to defend the territory because we cannot live without it," said Batista, who was trained by a local Indigenous association, the Conselho Indígena de Roraima, as part of an initiative called Rede Wakywai, which means "our news" in the local Wapichana language.

ADVANTAGES AND DISADVANTAGES OF AI IN EDUCATION
As artificial intelligence becomes more common in our daily lives, its effect on education calls for both enthusiasm and caution. Supporters believe that AI offers great opportunities for personalized learning, making administrative tasks easier and bringing new ways to teach. However, there are still worries about privacy, fairness and the possibility of replacing traditional teaching jobs. A study by the Digital Education Council found that 86% of students admit to using AI in their studies. To further that, 24% use it daily and 54% use it weekly. What is artificial intelligence in education?
Artificial intelligence in education refers to the use of computer systems that can perform tasks typically requiring human intelligence to enhance learning experiences, streamline administrative processes, and support educators. AI technologies include machine learning, natural language processing and robotics, which can personalize learning by adapting content and pace to individual student needs. This personalized approach helps address diverse learning styles and paces, ensuring that each student receives the attention and resources they need to succeed.
In addition to personalized learning, AI can assist educators by automating administrative tasks. By reducing the time spent on these repetitive tasks, teachers can focus more on instruction and student engagement. AI-powered tools can also provide insights into student performance and progress, enabling early intervention for those who may be struggling and recognizing those who excel. This data-driven approach allows for more informed decision-making and tailored support for students. AI in education can facilitate innovative teaching methods and interactive learning environments. As AI continues to evolve, its potential to transform education by making it more accessible, efficient and personalized becomes increasingly evident.
The role of Artificial Intelligence in education is rapidly transforming how students learn and how educators teach. AI-powered tools enable personalized learning experiences, adapting content and pace to meet individual student needs. Intelligent tutoring systems, automated grading and virtual assistants enhance both teaching efficiency and student engagement. By analyzing learning patterns, AI can also help identify struggling students early, allowing for timely intervention and support. Another key aspect of the role of AI in education is its ability to improve accessibility and inclusivity. AI-driven platforms can provide real-time translations, speech-to-text capabilities and adaptive learning materials for students with disabilities. Moreover, educators benefit from AI by gaining data-driven insights into curriculum effectiveness and student performance. As the technology continues to evolve, AI holds the potential to create more equitable and effective educational environments worldwide. Artificial intelligence is revolutionizing various sectors and education is no exception. The integration of AI in education has brought about significant changes that enhance learning experiences, streamline administrative tasks and support both students and educators in various ways.
As artificial intelligence continues to integrate into various sectors, its application in education is both celebrated and scrutinized. While AI holds significant potential to transform learning experiences, it also presents several disadvantages that need careful consideration that must be addressed to ensure a balanced and effective learning environment. Another major concern is the growing dependence on technology that AI in education fosters. As educational institutions increasingly rely on AI-driven tools for teaching, assessment and administrative tasks, there is a risk of becoming overly dependent on these technologies. This dependence can lead to significant disruptions in the event of technical failures or cyber-attacks. Furthermore, it may also diminish the development of critical thinking and problem-solving skills among students, as they may become accustomed to AI systems providing answers and solutions.
The lack of human touch is another critical disadvantage of AI in education, leading to a dehumanized learning experience. Traditional education relies heavily on human interaction, with teachers providing not only academic instruction but also emotional support and mentorship. AI systems, while efficient, cannot replicate the empathy, understanding and personal connection that human educators offer. This absence of human elements can affect students' social and emotional development, as well as their overall engagement and motivation in the learning process. AI in education also raises the risk of cheating. Advanced AI tools can be exploited by students to find ways to bypass academic integrity measures. For instance, AI-powered plagiarism detection systems may themselves be outsmarted by sophisticated AI-generated content that mimics genuine student work. Additionally, AI-based tutoring systems and automated assessments might be manipulated to provide undue assistance, undermining the fairness and integrity of academic evaluations. Schools and institutions must continuously adapt and update their AI tools to mitigate these risks.
Lastly, the rise of AI in education brings the concern of teacher job displacement. As AI systems take on more roles traditionally filled by educators, there is a fear that teachers may become obsolete. Automated grading, AI-driven tutoring, and administrative tasks handled by AI could reduce the need for human teachers, leading to job losses and a devaluation of the teaching profession. While AI can certainly support and enhance educational practices, it is essential to balance its implementation to ensure that teachers remain integral to the educational process, providing the human touch that technology cannot replace.

Becoming
Back in the ancestral homeland of Michelle Obama, black women were rarely granted the honorific Miss or Mrs., but were addressed by their first name, or simply as "gal" or "auntie" or worse. This so openly demeaned them that many black women, long after they had left the South, refused to answer if called by their first name. A mother and father in 1970s Texas named their newborn "Miss" so that white people would have no choice but to address their daughter by that title. Black women were meant for the field, or the kitchen, or for use as they saw fit. They were, by definition, not ladies. The very idea of a black woman as first lady of the land, well, that would have been unthinkable.

“Riding a bicycle wil save you money, create less pollution, make you _______ and let you zip past heavy traffic. Will anything persuade auto owners to hop on a two-wheeler? Absolutely yes, says a new report from Washington’s Worldwatch Institute. In “Taking Bikes Seriously,” senior researcher Gary Gardner shows how cities around the world have increased bike ridership by offering a little encouragement. The city of Copenhagen, _________ , makes 2,300 bicycles available for public use; the $3 rental fee is refunded when the bike is returned. In Lima, Peru, lowincome residents ________ buy bicycles through a special small-loan program. During the 1980s Japan helped bikers by boosting the number of bicycle parking spaces at railway stations about fourfold, to 2.4 million. That strategy _________ both money and land; two bikes can fit into a square meter of parking space, while cars require about 30 sq m each. Bike-friendly policies ______ western Germany have lifted the amount of cycling by 50% since the early 1970s.”

Palestinians in Gaza Reflect on One Year of Israel’s War With Hamas Oct. 7, 2024
The war has killed tens of thousands and devastated entire cities, leaving many in Gaza without a home and fueling a humanitarian catastrophe.
By Bilal Shbair and Hiba Yazbek Reporting from the Gaza Strip and Jerusalem.
Last October, Fadi Abu Kheir of southern Gaza had big plans. He was going to be engaged to the woman he loved. After they got married, he said, they would move in together, into an apartment that he spent years building.
“Now,” Mr. Abu Kheir, 24, said, “I am clueless about my future. I cannot even think how I can adapt to life postwar.”
It has been a year since the Hamas-led terrorist attacks impelled Israel to launch a retaliatory offensive in Gaza. For Mr. Abu Kheir — and, indeed, for Palestinians across the enclave — every day since, he said, has teemed with “sadness, depression and fury.”
The war has killed over 41,000 people, according to Gazan health officials, and devastated entire neighborhoods and cities, leaving hundreds of thousands without a home and fueling a humanitarian catastrophe.
More than 2 million people lived in the strip before the conflict. No one has been unaffected.
“We were so happy before this war,” said Maisaa al-Naffar, 20, of Khan Younis, breaking into tears as she recalled her first few weeks as a newlywed before the war began. She added: “I am not the person I used to be.”
Nine months pregnant, she is sheltering in a tent in southern Gaza.
“I miss my old life. I miss the days when we used to have fun or laugh at even the smallest things.
I miss my life when we had enough healthy food and snacks,”
Ms. al-Naffar said. “Today, everything has become a hell, full of dust and darkness.”
Throughout the enclave, similar stories abound. For Mr. Abu Kheir, the image from the war that lingers is that of a naked, lifeless woman lying in the street, blown out of a house that had been bombarded, he said. The conflict has killed two of his best friends, and displaced him and his family, he said. It also destroyed the apartment he was building, in the southern Gaza city of Rafah. The war, he said, has “destroyed my dreams.”

What does a sustainable smartphone look like?
In a bid to reduce global electronic waste, Fairphone has created a smartphone that owners can repair themselves. What makes its technology so sustainable?
"This is my phone's camera," says Bas van Abel, holding a small, square component aloft. He has just removed it from his smartphone, using a tiny screwdriver.
"There's eight components in total which can be removed and replaced," he says, as he meticulously disassembles his entire smartphone, placing the camera alongside his phone battery, USB port, screen and loudspeaker.
Van Abel is the co-founder of the Dutch social enterprise Fairphone, which claims to have built "the world's most sustainable smartphone". But with a complex product containing rare metals and components from all over the world, just how sustainable can a smartphone be?
Founded in 2013 in Amsterdam, Fairphone makes Android smartphones which can easily be exchanged, customized and repaired by their owners. By enabling and encouraging people to fix their phones, rather than throwing them away as soon as a component breaks, Fairphone hopes to help reduce electronic waste.
