Education

500 students share one computer in Niger. Yet they're conducting advanced physics experiments that students at elite schools can't access. The secret? WebAR turning basic smartphones into portable STEM labs. Think about that. In Sub-Saharan Africa, fewer than 10% of schools have internet. Student-to-computer ratios hit 500:1. Yet mobile subscriptions jumped from single digits to 80% in a decade. Students already carry the infrastructure—we just weren't using it right. Traditional EdTech Reality: ↳ VR headsets: $300+ per student ↳ Heavy apps requiring 5G speeds ↳ Labs costing millions to build ↳ Rural schools: permanently excluded The WebAR Revolution: ↳ Runs in any browser, optimized for 3G ↳ No app store, minimal storage ↳ Science scores improving 10-15% ↳ Every smartphone becomes a laboratory But here's what grabbed me: A physics teacher in rural South Africa has one broken oscilloscope. No budget. Her students scan printed markers, and electromagnetic fields pulse across their desks. They run experiments infinitely—no equipment damaged, no reagents consumed. One student told her: "Engineering is for people like me now. The lab fits in my pocket." What changes everything: ↳ Mobile-first matches actual connectivity ↳ Browser-based works offline ↳ Teachers need training, not new buildings ↳ Inequality becomes irrelevant The Multiplication Effect: 1 teacher with markers = 30 students experimenting 10 schools sharing content = communities transformed 100 districts adopting = educational equality emerging At scale = STEM education without infrastructure gaps We spent decades waiting for labs that won't arrive. Now any browser becomes one. Because when a student in rural Africa explores the same 3D molecules as someone at MIT—using the phone already in their pocket—you realize: WebAR isn't shiny technology. It's a quiet equaliser making world-class STEM education fit into 3G connections and $50 phones. Follow me, Dr. Martha Boeckenfeld for innovations where accessibility drives transformation. ♻️ Share if you believe quality education shouldn't require perfect infrastructure.

🥦Spain is leading the way on healthy sustainable school food 🇪🇸 In 2022 Spain updated its dietary guidelines to be more in line with the latest science on healthy sustainable diets (EAT-Lancet Planetary Health Diet). Now they are pioneering implementation -- having just passed a new royal decree on school food that brings what is served in line with NDG recommendations. The aim of this decree is for all children, regardless of family income level, to have access to healthy, nutritious meals at school. 🌟Highlights 🥩Meat to be served maximum three times a week. Red meat maximum once a week, processed meats maximum twice a month 🍇Focus on local, seasonal food -- 45% fruit and veg served must be in season 🫘Ramping up legumes -- to be served 1-2 times a week minimum in a variety of ways including as primary protein source in a main, or as part of a starter or side dish. Only 14% of schools currently serve legumes once a week 🚫Limits on processed foods -- pre-prepared options like pizzas, empanadillas, and croquetas can only be served once a month, and sugar-sweetened beverages, energy drinks and processed snacks will be banned from vending machines and school cafes 🍆Fully plant-based menus available for children who want them ⏰The new decree comes into effect next term, in all 17.000 Spanish schools (primary and secondary, public and private) This is an amazing step forwards, and I'm excited to see healthy sustainable food in Spanish school canteens. To ensure the policy vision becomes a reality on the 'school floor', compliance monitoring and enforcement will be key, as well as securing catering suppliers who are able to rapidly meet these new needs.

Louder for the people at the back 🎤 Many organisations today seem to have shifted from being institutions that develop great talent to those that primarily seek ready-made talent. This trend overlooks the immense value of individuals who, despite lacking experience, possess a great attitude, commitment, and a team-oriented mindset. These qualities often outweigh the drawbacks of hiring experienced individuals with a fixed and toxic mindset. The best organisations attract talent with their best years ahead of them, focusing on potential rather than past achievements. Let’s be clear this is more about mindset and willingness to learn and unlearn as apposed to age. To realise the incredible potential return, organisations must commit to creating an environment where continuous development is possible. This requires a multi-faceted approach: 1. Robust Training Programmes: Employers should invest in comprehensive training programmes that equip employees with the necessary skills for their roles. This includes on-the-job training, mentorship programmes, online courses, and workshops. 2. Redefining Hiring Criteria: Organisations should revise their hiring criteria to focus more on candidates’ potential and willingness to learn rather than solely on prior experience or formal qualifications. Behavioural interviews, aptitude tests, and probationary periods can help assess a candidate's ability to learn and adapt. 3. Partnerships with Educational Institutions: Companies can collaborate with educational institutions to design curricula that align with industry needs. Apprenticeship programmes, internships, and cooperative education can bridge the gap between academic learning and practical job skills. 4. Lifelong Learning Culture: Encouraging a culture of lifelong learning within organisations is crucial. Employers should provide ongoing education opportunities and support for professional development. This includes continuous skills assessment and access to resources for upskilling and reskilling. 5. Inclusive Recruitment Practices: Employers should implement inclusive recruitment practices that remove biases and barriers. Blind recruitment, diversity quotas, and targeted outreach programmes can help ensure that diverse candidates are given a fair chance. By implementing these measures, organisations can develop a workforce that is adaptable, innovative, and resilient, ensuring sustainable success and growth.

Let’s talk about hidden disabilities—ADHD, dyslexia, anxiety, and others that don’t meet the eye. Too often, these students are left to struggle because their needs aren’t immediately visible. But here’s the thing: when we ignore those needs, it’s no different from denying someone in a wheelchair access to a ramp. Think about it. Would you expect someone to climb stairs without the tools they need? Of course not. Yet we often expect students with hidden disabilities to navigate education without the accommodations that would level the playing field. It’s not fair, and it’s not right. Accommodations like extra time, clear instructions, or a quiet space aren’t “special treatment.” They’re the difference between drowning and swimming. They’re the tools these students need to show us their potential, not their struggles. I’ve seen the power of a single adjustment. They’re what happens when we meet students where they are. What if we reimagined education as a place where every student feels valued and equipped to succeed? What if we stopped seeing accommodations as “extras” and started recognizing them as essential? Here’s a question for you: Have you seen examples of simple accommodations making a big impact? Or do you think schools are doing enough to support students with hidden disabilities? Let’s share, reflect, and push for better together. Image Courtesy: No Nonsense Neurodivergent #Disability #Accessibility #SDGs #Equity #HumanRights #WeAreBillionStrong ID: Allowing a student with a hidden disability (ADHD, Anxiety, Dyslexia) to struggle academically or socially when all that is needed for success are appropriate accommodations and explicit instruction, is no different than failing to provide a ramp for a person in a wheelchair.

Ever wake up just before your alarm? It might not be a coincidence… It turns out, our brains have a natural way of keeping track of time, an inborn “clock” mechanism, which is synchronised to light in our environment. It’s got the coolest name for such a tiny brain region: the suprachiasmatic nucleus (SCN) - literally, the group of cells (nucleus) above (supra) the optic chiasm (crossing). The SCN is essentially your brain’s “master clock” because it is responsible for coordinating our circadian rhythms. Light-sensitive cells in your eyes send signals to the SCN, which regulates melatonin - a hormone that makes us sleepy - via the pineal gland. Our species evolved to be diurnal, being active in the day and sleeping at night. As a result, daylight inhibits melatonin release, making us more alert. At night, the lack of light promotes melatonin release, making us sleepy. This is why for better sleep hygiene, experts often recommend limiting exposure to electronic devices for at least an hour before bedtime. The light from electronic devices can shift your body clock and this gets aggravated by heightened anxiety associated with doom scrolling -- neither of which helps your sleep. Want to support your brain’s internal clock? A few simple habits can make a big difference: 👉 Get natural sunlight in the morning. This helps reset your body clock. 👉 Stick to a consistent sleep schedule, even on weekends. 👉 Limit screens at least an hour before bed. 👉 Keep your bedroom dark and cool to promote better sleep. BTW, in teenagers melatonin starts to be produced later at night, which is why many teenagers don’t feel sleepy until much later in the evening. It’s also the reason they struggle to get up in the morning. For teens, going to school early is a bit like forcing them into a different time zone during the week and only letting them reset on weekends. When your teenager sleeps in on the weekends, bear in mind they are dealing with a genuine biological change in their circadian rhythm during the teenage years. So when you wake right before your alarm, blame (or credit!) your suprachiasmatic nucleus for being such a good time keeper! Understanding our biology helps us work with our natural rhythms rather than against them. How do you optimize your daily schedule around your circadian patterns?

I have a DEI secret… And it’s a big one. Ready? The accommodations I make for my neurodivergent team members… Also benefit my neurotypical team members. Ground breaking, right? 😏 I hear a lot about companies pushing back on accommodations, but I thought I’d show you just a few of the simple things we do here. I’ll use myself as the example, and let you see how it helps everyone. 👉 I like to sit on my legs and fidget in my chair. ✨ So we’ve got comfy chairs, wider than your standard office ones, for everyone. 👉 I regularly forget my breakfast or lunch. ✨ So we keep a fully stocked drinks fridge and snack cupboard. Open to everyone. 👉 Sometimes I find the main office overwhelming when I’m trying to focus. ✨ So we created two quiet workspaces in different rooms. Everyone can use them when it all gets a bit much. 👉 I used to get anxious about calling in sick and having to justify it to my old manager. ✨ Now? Just send a text. No explanations needed. If you say you’re ill, that’s enough. Applies to everyone. 👉 I had a habit of staying too late, sometimes working 3 or 4 hours longer than I should. ✨ So we finish at 4pm. And we mean it. Everyone is made to down tools and heads off. No late-night badge of honour here. I could go on, but you get the idea. There’s really no excuse not to make accommodations for your ND teammates. Because when you do… It makes things better for everyone.

Major update on our work: In the last few years, a flood of new research has altered the landscape of the debate around kids, smartphones, and social media. 1️⃣ First, there is now a lot more work revealing a wide range of direct harms caused by social media that extends beyond mental health (e.g., cyberbullying, sextortion, and exposure to algorithmically amplified content promoting suicide, eating-disorders, and self-harm). These direct harms are not correlations; they are harms reported by millions of young people each year. 2️⃣ Second, recent research — including experiments conducted by Meta itself — provides increasingly strong causal evidence linking heavy social media use to depression, anxiety, and other internalizing disorders. (We refer to these as indirect harms because they appear over time rather than right away). Together, these findings allow us to answer the product safety question clearly: 📣 No, social media is not safe for children and adolescents. The evidence is abundant, varied, and damning. We have gathered it and organized it in two related projects which we invite you to read, in this post: https://lnkd.in/eAvfH3aQ

A learning culture is not built by offering more training. It emerges where curiosity, connection, and purpose intersect. Andrew Barry, in The Curious Lion, describes learning culture as a lotus where several forces overlap. I find this framing helpful because it moves the conversation beyond HR programs and into the fabric of the organization. At the individual level, there is curiosity. People must feel invited to ask questions, challenge assumptions, and explore. Without individual curiosity, learning remains compliance. At the organizational level, there is mission. Learning needs direction. When people understand what the company stands for and where it is going, their curiosity becomes focused rather than scattered. At the relational level, there is human connection. Learning accelerates in environments where people feel safe to speak, experiment, and reflect together. The fourth circle is continuous learning. Learning must be ongoing, not episodic. Not a workshop, but a way of operating. Continuous learning ensures that curiosity, mission, and connection reinforce each other over time rather than fading after the latest initiative. When these circles overlap, deeper elements emerge: Shared vision aligns effort. Shared experiences create collective memory. Shared assumptions shape how reality is interpreted. Shared stories transmit meaning across generations. At the center sits what we call learning culture. Not an initiative, but a pattern of how people think, relate, and evolve together. The question for leaders is not, “Do we offer learning opportunities?” It is, “Do curiosity, mission, and connection truly reinforce each other continuously in our organization?” That is where learning becomes cultural rather than occasional.

What do you do if you’re a freshman in college today? A family friend’s son is starting college this fall, and they asked me what he should study. A simple question -until you really think about it. By the time he graduates in 4 years, the world will look nothing like it does today. The education system won’t change overnight but the job market will. For decades, the logic of higher education was clear: Get a degree → land a junior role → learn by doing → climb the ladder. But now, the tasks that defined entry-level work - summarizing reports, drafting emails, analyzing data - can now be done instantly, at near-zero cost. These weren’t just chores; they were how young employees built judgment, intuition, and experience. And so I keep coming back to this question: if entry-level jobs disappear, where does experience come from? Much of the work that once bridged the gap between “student” and “professional” can now be done instantly, at near-zero cost. Ironically, education may flip. It used to be vocational at the bottom (trade schools) and theoretical at the top (college). But if AI removes the need for junior roles, will universities start training students directly for higher-level decision-making? Will 'entry-level' begin to disappear entirely? If AI continues to eat away at junior roles, colleges will eventually have to change. Maybe that means: 〰️ More apprenticeship models. Real-world experience will matter more than degrees. 〰️ Less focus on knowledge, more on decision-making and creativity. “What’s the right answer?” will be less valuable than “What are the trade-offs?” 〰️ AI-native professions. Knowing how to wield AI, but also where it breaks, will become its own form of expertise. For today’s students, the challenge isn’t just choosing a major - it’s figuring out how to gain experience when experience itself is being automated. If I were 18 today, I’d focus less on what to study and more on how to build - skills, projects, networks. If you were 18 today, how would you approach the next four years? (Pls tell me so I can pass on the advice)

I graduated from the Wharton MBA a year ago, and here’s what I wish someone had told me before I started about recruiting, mindset, and social life. If you're starting this fall, this is for you! 1️⃣ Business school is a buffet (and you'll get indigestion if you try everything) First few weeks - take stock of everything it has to offer. Internships, fellowships, clubs, accelerators, etc. Then ruthlessly prioritize. Take what serves you and leave the buffet. (You’ll still feel FOMO and take on more than you should because you “paid for it” - that’s all part of the process!) 2️⃣ Pivoting is harder than you think Most people don’t get this until it’s too late - employers don’t recruit from MBA programs because they care that you have an MBA. They do it because MBAs filter for experiences/skillsets they want. You need to show them why you can do the job. The degree just gets you in the door - use the network to get the experience and build the skills. More people than you'd think go back to their old industries. 3️⃣ You'll have your "maybe I should recruit for consulting" moment Or banking. Even if you swore you'd never. We all do. When everyone's doing it, you'll second-guess yourself. That's normal! Just remember why YOU came to school. Stick to your plan, not theirs. (Unless your plan was to recruit for consulting/banking) 4️⃣ The social scene is middle school, except people have money (but it’s not all bleak) Hundreds of type-A personalities in one place and a lot of bankers/consultants who didn’t have enough fun in their 20s = drama, hyper-socialization. Who's dating who, who got the Goldman interview, who wasn't invited to that trip…People will talk about you if you stand out (for good or bad reasons). First semester feels intense, especially if you’re an introvert. By second year, everyone chills out and you find your people. 5️⃣ You'll need to touch grass B-school is a bubble. If you're not careful, you'll think comparing signing bonuses and taking out loans to go on another trip with 20 people you just met are real life. See non-MBA friends. Call your family. There’s a hive-mindedness in business school. Don’t lose yourself in it. 6️⃣ The classes are hit or miss (so be strategic) You’ll keep some class notes for decades to come (If you’re going to Wharton - Negotiations, Legal Aspects of Entrepreneurship, Scaling Operations to name a few). You’ll throw away others before the semester is over. Talk to second-years about which classes are actually worth optimizing to get into. Bonus: Do something unexpected. Join the club you think you'd hate. Take the class outside your comfort zone. I signed up for a week-long backpacking trip in the Andes despite every instinct not to and ended up leading a trip to Antarctica my 2nd year (best MBA memory!). People getting an MBA: What's the one thing you're nervous about as you start your MBA? People who have an MBA: What’s the piece of advice you wish you got before you started?
