Here’s how Rachel works

Anyone can purchase Rachel from an online store run by its creator, World Possible, at https://worldpossible.org/rachel.

It’s not a money-making exercise: the site even includes instructions for building one’s own version of Rachel.

When it is switched on, anyone with a Wi-Fi-enabled device can look for “Rachel” under the list of Wi-Fi networks, connect to it, open a web browser and type the address listed on the device.

This instantly gives access to offline versions of more than a hundred free educational websites, like Wikipedia and Khan Academy, without any data charges.

For those with internet access, a full list of these resources can be browsed from anywhere at the Open Educational Resources website, http://oer2go.org. It ranges from African stories to world maps.

World Possible points out another massive benefit of its device: “Rachel can instantly turn a graveyard of unused computers into a learning centre. For the 53% of people around the world without an internet connection, Rachel is a valuable tool that connects offline learners to the best free educational resources.

“Rachel is rugged, lightweight and designed to travel anywhere. It is used by schools, libraries, community centres, orphanages and the NGOs supporting them all over the world.”

Two sizes are now available: Rachel-Plus and Rachel-Pi.

Both come pre-loaded with content from OER2Go and a router that connects to multiple devices.
