Connexions is an educational platform for developing, sharing, and publishing instructional material on the web. They’ve developed a modular concept of learning by which content is parceled into modules, or smaller chunks of info which are more easily digested and can be arranged and linked in many different ways.
Educators may browse the site by subjects, keyword, or simply by using the search box. To add or create a model, users first need to register, from there, they can convert Word docs or start from scratch. As all content is submitted and distributed under a Creative Commons attribution license, it can be used freely by teachers and students alike.
CNS.org In Their Own Words
“Connexions is an environment for collaboratively developing, freely sharing, and rapidly publishing scholarly content on the Web. Our Content Commons contains educational materials for everyone — from children to college students to professionals — organized in small modules that are easily connected into larger collections or courses. All content is free to use and reuse under the Creative Commons “attribution” license.”
Why CNS.org It Might Be A Killer
Learning shouldn’t have a price. Connexions promotes the free flow of educational materials giving instructors and educators everywhere an alternative means of teaching. Rather than relying on linear textbooks, Connexions’ modules provide a flexible and adaptable learning tool. All content can be customized, printed, mixed, and published; it’s up to the teacher. Seems like a great way to open up learning.
