The pronoun IT (line 11), refers to:

The time to embrace change in education is right now! In fact, it’s long overdue. Did you know that the model for modern-day public education was created by the need for on-time mechanical workers during the industrial revolution? That was certainly a technological disruption, but it happened 250 years ago. It’s what we call the front-lead method, and it’s not the best model for addressing the learning needs of many students: divergent thinkers, neurodiverse minds, creatives, scientists, and the list goes on. Which brings us to our next point: it’s time for the next wave of disruption. Luckily for us, it’s here. And it’s been here since 1989, when Tim Berners-Lee — a British scientist from CERT — invented the World Wide Web. We know, you use the internet every day, and it’s great, but maybe you’re skeptical that it can revolutionize education. Well, if you didn’t know, it already is. A large body of evidence-based, peer reviewed work points to the web as one of the central hubs for positive educational change today. It’s our connection to others, our access to a world of educational resources, it’s a format that works for many learners, it’s at the heart of countless services (that don’t work in an unconnected world), and it’s driving access to education.
