Google has announced a new online education tool called Oppia. An open source project, it aims to let anyone create online interactive activities for learning.

The Oppia site essentially offers a basic form of coding that lets anyone create or take explorations, which is what the lessons are named. These explorations can be left open so others taking them are able to edit the way code reacts, ultimately creating a smarter lesson.

Google describes Oppia as: "A smart feedback system that tries to 'teach a person to fish', instead of simply revealing the correct answer or marking the submitted answer as wrong."

Explorations can be embeded in any webpage, feature an online analytics dashboard for easy improvements, the ability to change parameters to suit a learner, and collaborative editing.

There is a disclaimer that states Oppia is not a Google product, suggesting the big G hopes a community will take over the tools to create something greater. The eventual goal is to take learning beyond just reading and watching videos. As the company says: "One does not learn to play the piano by watching videos of many virtuoso performances."
