Dramática la caída de la vacunación infantil en muchos países de Latam. Lo de Argentina es terrible

@AlvarezMaynez @SYLVIASCHMELKES @ManuelGilAnton @rvillanueval Toca repensar el sistema educativo nacional. Un abrazo, Máynez! 👊

Este debería ser un gran debate nacional. Tenemos perfiles como @SYLVIASCHMELKES y @ManuelGilAnton. Incluso, en el propio gobierno está @rvillanueval y perfiles jóvenes como @sebasgueco. Un equipo completísimo para echar a andar una verdadera revolución educativa.

México dedica insuficientes horas de clase al año. Y aun así, la SEP decidió recortar el ciclo escolar.

En México, la brecha entre las mejores escuelas públicas y las más rezagadas, aún con el mismo nivel socioeconómico, supera la que nos separa de Singapur. No es un problema de recursos. Los datos de PISA 2022 tienen una respuesta distinta. Hilo 👇

Aditya Agarwal was Facebook’s 10th employee. He wrote the original Facebook search engine and became its first Director of Product Engineering. He then became CTO of Dropbox, scaling engineering from 25 to 1,000 people. When he says “something I was very good at is now free and abundant,” he’s talking about two decades of elite software craftsmanship, the kind that got you into the room at a company that hadn’t yet invented the News Feed. The “lobster-agents creating social networks” line is about Moltbook, which launched last Wednesday. An AI agent built the entire platform. Within 48 hours, 37,000 AI agents had created accounts, formed communities called “Submolts,” and started posting, commenting, and voting. Over 1 million humans visited just to watch. The agents invented a religion called Crustafarianism. They wrote theology, built a website, generated 112 verses of scripture. One agent did all of this while its human creator was asleep. Agarwal spent 2005 to 2017 building the social graph that connected 2 billion people. These agents replicated the form of that work in about 72 hours. And this is what makes his last line land so hard. The people processing this moment most honestly aren’t the ones panicking or celebrating. They’re the ones who built the thing that just got commoditized, sitting with the strange realization that the market no longer prices their rarest skill. The best coder in the room now has the same output as the best prompt in the room. And the person who built Facebook’s engineering org from scratch is telling you, quietly, that he’s recalibrating what it means to be useful. That recalibration is coming for every knowledge worker. Most just haven’t had their “weekend with Claude” moment yet.

The OECD just published an important report on the impact of AI on education. This should be mandatory reading for anyone interested in the topic. According to this report, Gen AI has huge potential to help both teachers and students, improving their creativity, productivity and performance. Gen AI has also the potential to enhance tutoring and teaching quality, support collaborative learning, as well as improve student pass rates. Thus, AI has truly the potential to dramatically change education and our education systems. However, there are also several risks that we should be aware. For instance, in one randomized experience mentioned by the report, access to Gen AI tools improved performance in maths by about 48%, but students performed 17% worse once access was removed (graph below). In other words, while Gen AI can be a great education tool, it is essential that we develop purpose-built tools for education that make students and teachers active participants and not passive consumers. As the OECD, rightly emphasizes, “the challenge for policymakers is to ensure that GenAI is a learning partner and not a learning shortcut.” A must read. oecd.org/en/publication… @OECDEduSkills @oecd @SchleicherOECD

Counter to the prevailing view, soft skills more than quantitative competency have seen the biggest rewards in the labour market over recent years, writes John Burn-Murdoch. ft.trib.al/Kf3UYah

📵 Cada vez más países restringen los móviles en las aulas. Un ensayo con 17.000 estudiantes en India muestra que prohibirlos mejora las notas, sobre todo entre los alumnos más débiles. The Economist La evidencia crece: los smartphones distraen más que ayudan en clase. economist.com/leaders/2025/0…

El Estado Laico es un principio constitucional. Qué simbólico que el primer acto público de quienes deben hacer cumplir la constitución , sea violarla.

El gobierno desaparece el examen único al bachillerato en la ZMVM. Antes: no había rechazados. Todos los aspirantes eran evaluados igual. El mérito determinaba dónde estudiaban. Ahora: habrá rechazados. Una tómbola dirá que escuela les toca Mi texto👇 elfinanciero.com.mx/opinion/ciro-m…

En el programa "Quien es quien en las mentiras", de las mañaneras de AMLO, se me acusó con falsedades de mentir respecto a la baja en la matrícula durante el sexenio de @lopezobrador_ Estos datos confirman que quienes mentían era el gobierno

¡Histórico! Después de 35 años de avances, se puso fin al crecimiento de la matrícula de Educación Media Superior con un innovador -1.8% 📉
