Growing Up With A.I.: A Multimedia Challenge for Teenagers and Educators
Show us - in words or images, audio or video - how this technology is affecting you and the teenagers you know. Contest dates: Sept. 10-Oct. 22, 2025.


What's it like to think, create, teach and learn at a time when artificial intelligence is transforming our world?

What do you think its rise will mean for the generation in high school now?

This fall, we invite students and educators to explore these questions, and then show - in words or images, audio or video - how this technology is affecting you and the teenagers you know.

We know we don't have to explain to anyone in a classroom today just how profoundly generative A.I. has changed life in and out of school since ChatGPT was released in late 2022. Our goal, instead, is to learn from you, our core audience of middle and secondary students and teachers.

What is it like to grow up alongside A.I.? How, if at all, have you used it? What about it is surprising,. interesting or exciting? What is concerning, perplexing, scary - or even boring? What do you wish more people understood? What can you show or tell from your unique point of view that might add nuance to the conversation? 

We can't wait to see what you'll make. Click on the topic headings below for more resources and details, and review the full rules here. You might also consider hanging this one-page announcement on your class bulletin board.

The Challenge

This contest asks you to address one or both of these focus questions:

• What's it like to think, create, teach and learn at a time when artificial intelligence is transforming our world?

• What do you think its rise will mean for the generation in high school now?


How you address them is up to you. You can take on any aspect of the topic, big or small, negative or positive. You can focus on your life in or out of school, and you can work alone or with others.

Structural and pedagogical problems hinder the use of technology


    Three out of four teachers in Brazil show support for the use of artificial intelligence (AI) as a teaching tool. They also say that the technology has impacted education both positively, with faster access to information, and negatively, as students lose their focus.

    The data can be found in an unprecedented survey by Semesp Institute, an organization that represents higher education providers. The study was carried out between March 18 and 31 with 444 public and private school teachers from kindergarten to high school located in all regions of Brazil.

    In the study, 74.8 percent of respondents partially or totally agree with the use of artificial intelligence in teaching. Despite this, just over a third (39.2%) of them said they always use it as a teaching tool.

    Even though educators believe it is important to use AI, they also report structural and pedagogical problems that prevent or hinder its employment. Further issues were reported in connection with its excessive use, especially by pupils. Among these problems are the lack of internet at school, the lack of training for teachers and also greater difficulty in holding students’ attention.

    “I sense students have become more dependent on research tools and immediate answers and have a hard time having resilience and patience and acting as problem solvers,” an anonymous teacher who took part in the survey said.

    Another one said: “Technology has advanced, but sometimes access to it at school is not satisfactory. Poor internet connection. The computer lab is a restricted space. No Microsoft Office in the mobile lab. The use of cell phones is impractical as students have no internet. Now, even the internet is restricted to teachers.”

    Just under half of the teachers (45.7%) declared that both teachers and students have access to computers and the internet where they teach. Another seven percent answered there is still no access to technology in their schools. 

    Teachers also report that technology has made students lose their focus. “The school can’t keep up with the use of new technologies at the speed that the students can, which leads to a mismatch between the lesson taught and the lesson that the students want. The unbridled use of social media and the high level of exposure of young people to these networks have undermined teachers’ contact with students,” one of the teachers stated.

    They were nearly born on a bus, Estha and Rahel. The car in which Babà, their father, was taking Ammu, their mother, to hospital in Shillong to have them, broke down on the winding teaestate road in Assam. They abandoned the car and flagged down a crowded State Transport bus. With the queer compassion of the very poor for the comparatively well off, or perhaps only because they saw how hugely pregnant Ammu was, seated passengers made room for the couple, and for the rest of the journey Estha and Rahel’s father had to hold their mother’s stomach (with them in it) to prevent it from wobbling. That was before they were divorced and Ammu came back to live in Kerala. 

    According to Estha, if they’d been born on the bus, they’d have got free bus rides for the rest of their lives. It wasn’t clear where he’d got this information from, or how he knew these things, but for years the twins harbored a faint resentment against their parents for having diddled them out of a lifetime of free bus rides.

Multiliteracy: the new basic skill for the 21st century classroom


    We increasingly engage with texts that draw meaning beyond written words from other sources. Images, sound, video clips and gestures (alone and in combination) all play central roles in how we communicate and interpret content.

    This multimedia approach is especially evident in online platforms and social media, where a single piece of content may blend written language with videos, graphics, photos and other visual elements. This change requires us to rethink what we mean by literacy.

    Nearly 30 years ago, a group of scholars, the New London Group, recognised the need for a broader understanding of literacy after observing a growing gap between the literacy needs students faced outside of school and the print-based practices still dominant in classrooms.

    They introduced a concept of multiliteracies which acknowledges that we now engage with texts that use multiple modes of communication. We engage with these texts in different media environments, each with their own practices and strategies.

    The concept incorporates the literacy skills needed to acquire, interpret, produce and evaluate the multimodal and multimedia texts we encounter today.

    For literacy education, this shift means updating classroom aims, content and activities. The group developed a pedagogical framework to help schools respond to the growing inequalities and rapid changes in technology and the textual landscape.

    The process starts with examining pupils’ everyday literacy practices and experiences together. Then these practices are approached analytically by introducing a metalanguage for discussing the resources they use to create meaning. Students can use this metalanguage to critically evaluate their literacy practices which helps them understand how different modes of communication work and how to use them effectively.

    The pedagogy of multiliteracies also emphasises the design and production of multimodal texts and collaborative learning in linguistically and culturally diverse groups, rather than individual reading activities. […]

    Multiliteracies are already included in many European curricula, and the European framework for key competencies for lifelong learning defines literacy in a way that aligns with the concept of multiliteracies. These policy documents and guidelines provide a foundation for integrating multiliteracies into literacy education.

    Yet, research shows that there is still work to be done to incorporate teaching multimodal literacy practices into mainstream literacy education. While many teachers do include multimodal texts in their classroom activities, tensions between multimodal and traditional practices still exist.

    Studies point out the huge challenges teachers face when they adapt their teaching to the redefined literacies, and there are concerns about teachers’ preparedness to teach multiliteracies. They need support with training and appropriate materials. Teacher educators and policy makers must ensure that teachers have substantial and concrete support.

PROFESSOR DE LÍNGUA INGLESA:

THE DIGITAL FRONTIER OF FIDELITY

The Nuances of Micro-cheating: Social Practice or Digital Paranoia ?  


In the contemporary landscape of interpersonal relationships, the ubiquity of social media has recalibrated the traditional parameters of faithfulness. The emergence of the term "micro-cheating" serves as a testament to this shift, encompassing a spectrum of subtle, digitally-mediated behaviors that, while devoid of physical consummation, suggest an emotional or erotic redirection. Such actions— ranging from the seemingly innocuous "double-tap" on an expartner’s archived photograph to the deliberate concealment of encrypted message threads—occupy a contentious "grey area" that challenges the binary definition of infidelity.  

From a socio-psychological perspective, micro-cheating is often interpreted not as an isolated act of betrayal, but as a symptom of the "validation economy." The digital architecture of modern platforms encourages a constant pursuit of external approval, where a notification can function as a dopamine-inducing ego boost. Consequently, the ambiguity of intent becomes the focal point of the debate: is the digital interaction a legitimate exercise of social autonomy or a covert erosion of the primary partnership’s exclusivity? Proponents of the concept argue that the "secrecy criterion" is the ultimate litmus test—if an interaction is intentionally shielded from a partner’s view, the threshold of trust has likely been breached.  

Conversely, skeptics caution against the pathologization of digital sociability. They argue that the expansion of the "cheating" umbrella to include minor online interactions fosters a climate of hyper-vigilance and domestic surveillance, potentially undermining the very foundation of trust it seeks to protect. By labeling these behaviors as "micro-infidelities," we risk imposing a panoptic gaze on our partners, where every "friend request" is scrutinized for subversive intent.

For the language educator, this phenomenon provides a rich semiotic field for classroom reflection. Aligning with the National Common Curricular Base (BNCC), the study of such themes transcends mere grammatical decoding. It invites students to engage in "multiliteracies," analyzing how meaning is negotiated across digital platforms and how language (visual, verbal, and symbolic) shapes social ethics. In this sense, the English language is not merely a system of signs to be mastered, but a tool for critical agency in a globalized, hyper-connected world.

Hero boy swims for four hours to save his family (9th February 2026)


        A 13-year-old Australian boy has been hailed a hero after an epic swim that saved his family. The boy, Austin Appelbee, and his family were on a beach holiday in Western Australia. They were kayaking and paddleboarding in shallow water when strong winds pushed them farther offshore. They ended up over four kilometres away from land, and the daylight was fading. Austin decided to kayak to shore to get help. However, the waves had damaged his kayak, which had taken in water and flipped over. He said he then lost an oar and knew he was in trouble. He decided he had no alternative but to swim back to land. He swam through shark-frequented waters to raise the alarm.


        Austin made it to the beach and phoned for help. This sparked a huge rescue operation, which resulted in coastguards finding the teenager's mother and two younger sisters. The boy said: "I hit the bottom of the beach and I just collapsed, and then, after that, I had to “ sprint two kilometres to get to the phone." Rescuers called his efforts "superhuman". One rescuer said Austin's actions could not "be praised highly enough." He added that the teenager's "determination and courage ultimately saved the lives of his mother and siblings." Austin's mother Joanne, 47, told reporters: "The wind picked up. We lost oars, and we drifted out further. It was an absolute nightmare."

In the text about Austin Appelbee's rescue, several verbs and adjectives are used to describe the gravity and the outcome of the situation. Based on their specific usage in the passage, identify the alternative that CORRECTLY provides synonyms for the words "hailed", "sparked", and "siblings" without altering the original meaning.

Students using A.I. over humans to learn English (23rd December 2024)


        More and more students in Japan are using artificial intelligence (AI) to learn English and other languages. The language learning app Duolingo conducted a survey on how students study languages. More than 4,700 Japanese students answered questions about their language-learning habits. The survey found that the number of people using ChatGPT and other AI tools increased by more than 80 per cent in 2024. AI was particularly popular with younger people. The researchers said more young people used AI than took face-to-face lessons. However, some people in their 20s were not totally happy with AI lessons. They said AI lacked natural responses and was a little boring.


        Duolingo said: "We're in the midst of an AI revolution.…Technology has long had an impact on language learning." It found that apps were the most popular method in Japan to learn languages. English was the most studied language, followed by Korean. People are studying Korean "to understand the language as spoken by…favourite artists and celebrities." Duolingo said around 58 per cent of people who took the survey used language-learning apps. This was followed by video streaming platforms like YouTube and Netflix (37%), textbooks (36%) and online lessons (16%). The number of people going to a language school is decreasing. Just 13.8 per cent of people went to classes with a teacher.

Text 10A1-II


Beverly Hannett-Price‟s 67 years teaching at Detroit Country Day School has earned acclaim and notice in the Guinness Book of World Records. An assembly Monday crowded with students and staff toasted the 90-year-old‟s decades of uninterrupted classroom instruction marking her the longestserving female teacher of English as a foreign language.

“This historic recognition honors not only the length of Mrs. Hannett-Price‟s career, but the depth of her influence on students whose achievements span the worlds of entertainment, business, and the arts,” school officials said in a statement.

“She‟s had a lot of students and she kept in touch with me. She knew I needed more attention ... she befriended me. This is more than just a student-teacher relationship,” Courtney B. Vance, one of her former students, said Monday.

Guinness confirms Hannett-Price is the world‟s longestserving female language teacher, based on verified, uninterrupted years of classroom instruction documented across multiple institutions. In a statement on their website, Guinness said that “This record honors her lifelong commitment to her students, her school communities, and the teaching profession as a whole.”

Hannett-Price is known for her innovative and engaging teaching methods and creative assignments. “Even after more than 67 years in the classroom, she continues to educate with the same enthusiasm and energy that defined the start of her career,”Detroit Country Day officials said.

Building Trustworthy AI in Government: Enablers, Guardrails, and Engagement 







    Governments are starting to use AI in areas like public services, tax work, and disaster response. When it works well, AI can help people get answers faster, spot problems earlier, and support better decisions. As a result, AI can improve productivity, responsiveness, and accountability in government.
    However, many public AI projects stay in small pilots. This happens because governments often lack skills, good data, modern digital systems, and clear ways to measure impact. These gaps can also increase risk aversion, so teams avoid innovation even when the potential benefits are high.
    The OECD proposes a simple way to understand “trustworthy AI in government”: a framework with three connected pillars. In the figure, the goal is in the centre. Around it, the three pillars explain what governments must build and do, so they can reach the public value goals shown on the outer ring (productivity, responsiveness and accountability).
     Enablers are the foundations. They include strong governance, quality data, and digital infrastructure, as well as skills and talent in the civil service. They also require purposeful investment, smart public procurement, and partnerships with non-government actors, so that AI systems can be built and used reliably.
    Guardrails are the safety systems that guide AI use. They include ethics and risk management, transparency duties, and monitoring and oversight bodies that can check results over time. They can also be non-binding guidance or binding laws and policies, along with enforcement measures. Tools like impact assessment and auditing help keep these guardrails practical. Still, guardrails should be proportionate: not every rule fits every use case, or progress may stop.
    Engagement means involving the people who are affected. This includes working across levels of government, across policy areas, and with the broader ecosystem (civil society, businesses and researchers). It also includes citizens and civil servants, and sometimes collaboration across borders. Engagement pushes governments to design user-centred systems, listen to concerns, and make necessary adjustments.
     The main message is that trust is “unlocked” by the right mix. If enablers are weak, AI cannot scale. If guardrails are missing, harms grow. If engagement is shallow, solutions may look efficient but feel unfair, and trust can fall.

How do we measure attention?


    Attention, broadly defined, is the ability to direct the mind on a specific task, says Gloria Mark, author of Attention Span: A Groundbreaking Way to Restore Balance, Happiness and Productivity. There are two main types of attention, Mark explains. Involuntary attention is automatic—it’s what allows us to react to a loud noise or a jarringly bright light. Focalized attention, by contrast, is the ability to concentrate on a specific task. This latter type is what scientists measure when researching attention spans. 

    Since the early 2000s, Mark has tracked focalized attention by observing how long people remain on a task before switching to something else—such as checking email or opening a new browser tab. At first, Mark used in-person observations— researchers shadowed employees throughout the office. In recent years, she has tracked attention spans using software that monitors people’s computers.

    “Data from our first study, in 2003, revealed that people spent an average of 2.5 minutes on something before turning their attention to a different task,” she says, “Our most recent study done over the past five years shows that the figure has gone down to 40 seconds.” The measure doesn’t capture how long people can focus under ideal conditions, Mark notes, meaning shorter attention spans don’t reflect a permanent loss of attention capacity, but changes in how often people break their focus in daily life.
