The user arrives at a fairly clean page and they are asked what they want to learn. They are then shown the sequences of activities they should do do achieve it, and they can check off what they’ve already done, which is remembered for next time.

They check off when they’ve done them and get further suggestions.

For example, if they say they want to learn Scratch, they are given the following sequences to work though:

• Set up hardware
• Set up software
• Scratch
  • Getting started guide
  • Several activities

They would then get suggestions of what to learn next, e.g. Physical computing with Scratch.

They might have a more project-oriented aim, e.g. Making an irrigation system, which could have the following sequences:

• Set up hardware
• Set up software
• Python
  • Getting started guide
  • Several activities
• Physical computing
  • Digital Sensors
  • Analog Sensors
• Smart gardening

A sequence would be a series of practical activities, with related guides and videos. As the user gains experience they will move on from using line-by-line code examples to planning their own projects.
