During our work on the Radical School Change project we’ve found a lot of different internet resources that help share knowledge on the internet. Some of them are the platforms where people can put up and take other people’s courses, some have free lectures, and some help people collaborate on their research.

Here we list some of our favorite ones, let us know if you know more and we will be posting the updates regularly to this page.

TED Talks
Probably the better-known platform that hosts talks on technology, education and design. The good thing about TED is that you can start your own focused discussion next to each lecture, making it a great platform to meet like-minded people around very specific subjects of inquiry.

Khan Academy
A popular peer-to-peer learning portal. You can either be a student, put up your own courses, or help others to learn the stuff you already know. It caters more to college students, but may be a good place to refresh some of the basics.

Udemy
Another peer-to-peer educational portal. Anyone can put up a free or paid course online – most of them are presented as slide shows. Udemy is more practically oriented: you can learn about HTML5, programming, web design, marketing skills and stuff like that.

Coursera
A truly amazing resource that offers free courses from the leading US universities online. You can get free access to the study materials, video lectures, exercises, etc.

VideoLectures
Hosts hundreds of lectures from the world’s best professors (such as Mark Newman, who advanced network science dramatically over the past 15 years). You can also search lectures by university (e.g. Yale) or by the subject.

Mendeley
An academic collaboration network. Helps you keep track of all the papers you’re researching, organized by the subject. You can also start groups of research and add other people as well as the relevant publications in them. Could do with a social layer, but so far the best of the kind nevertheless.

iTunes
Surprisingly, iTunes has a huge selection of educational courses from the world’s best universities (both video and audio), but also – a huge range of educational podcasts. Just make a search for the topics or the author you’re interested in and probably you’ll find something you like.

Great Courses
Features complete courses on various subject from chaos to differential equations from the world’s best professors. It’s a bit of a one-way enterprise and the courses are expensive, but you can find some really good stuff on there.
