On February 10, 2017 a peer learning live meeting was organized between the Greek and the Polish school.

Aim: Teaching each other how to create an app for smartphones.

Lesson language: English

Software for development: App Inventor

Software for communication: Skype

Software for supervision: Teamviewer.

Description: In the beginning, Greek pupils taught Polish pupils the basics of how to develop an app for mobile devices. Greek pupils could see and guide Polish pupils because one computer from each side that was running the App Inventor software was connected with the other, using Teamviewer program.

At the end of the lesson the pupils developed together a special app that made use of the accelerometer sensor of smartphones. When the app was executed on the phone, a black screen was shown. When the mobile phone was shaken a broken glass sound was heard and a broken glass image was shown on the phone, as if the phone was broken.

The app was tested on both sides pupils' smartphones through a QR-Code.

Finally, the pupils proposed and applied their own enhancements and alterations to the app.
