Micro:bit begins testing with children:

• 1 cohort of sighted children as a group in a classroom setting
• 5-10 visually impaired students in a 1:1 setting
• 5-10 students with motor impairments in a 1:1 setting

The test with sighted children will require them to use MakeCode without a mouse/trackpad in order to confirm that it is usable.

The tests with visual impairments and motor impairments will help us identify gaps for those user populations.

We intend to have students work through 1-3 of the introductory micro:bit projects, with extensions if they move faster than expected.

• Name badge project
• Heart project
• Beating heart project

Completed features for this test:

• Focus can be on all of: toolbox, flyout, workspace, statement blocks, dropdown fields, text fields, number fields, connections (as needed), micro:bit icon field and its widget
• Focus and/or selection indicators meet micro:bit specifications
• Destination-first insertion workflow (navigate to insertion point, open toolbox, and select block)
• Keyboard shortcut dialog is accurate and navigable with the keyboard
• No invisible or meaningless tab stops
• No user-visible concept of a “mark”
• Keyboard copy and paste at cursor location
• Single focus between keyboard and mouse
• Chrome support
• All actions can be performed from the context menu
• Some actions can be performed from keyboard shortcuts
• Context menu shows keyboard shortcut information when appropriate
