From my initial sketches I created this lo-fi prototype which includes the major features of the product, namely viewing and setting up lessons with other classes around the world.

I then created 2 mid-fi prototypes in various colour schemes, with the correct brand typefaces. After testing these and speaking to users, I decided to create a single final prototype instead of 2 versions, as it is complicated for a teacher to manage multiple students working in pairs as opposed to a whole class, especially for music where the noise makes it hard to focus and play when the class is not playing the same music. Because of this I condensed both into a single prototype that will be controlled by the teacher and the students will be able to participate and interact with the other class as a whole as they appear on screen in front of the class.
