This app supports the evaluation of the integration of digital technologies into classroom activities. The app classifies the answers to a series of multiple choice questions related to the way in which technology is used within a teaching activity. It then indicates to what extent the use of digital technology within the activity replaces other technologies, amplifies what was possible with other technologies, or transforms learning through the affordances of digital technologies. The app utilises the RAT framework (http://techedges.org/r-a-t-model/ ) to assess the contribution of technology to the learning activity. To get the best from this tool try to use it to evaluate digital technology use across units of work rather than a single lesson or application.
