The reason the program layout and program code are on different tabs is to make sure it all fits properly on older screen sizes and can be used on iPads. I have considered making both of these tabs visible if pupils are working on a larger screen - what do you think?
We've had lots of schools using the program with pupils from Y1 to upper KS2. I spent a lot of time teaching with all primary year groups when developing the program, and wanted to keep it simple so all teachers could use it confidently. It does however have a lot of power too - have a look at how this unit for Y6 teaches pupils how to handle touch events and create apps EspressoCoding - Computing Made Simple - Activity v1.0.9.9.11 which respond proportionately to multi-directional swipes!
I'd be interested to hear how other forum members are getting on with it - we are always happy to hear constructive feedback and ideas!
Thanks!
