What role should/could the new technologies play in visible learning?

We are using many technologies to help teachers see their impact. We developed the New Zealand assessment scheme for elementary and high schools based on the model – it aims to provide teachers with information about their impact and where best next. It is voluntary to use and still the majority of teachers and schools use it – 16 years after it was first introduced. I am confident that more technologies that can help teachers “hear” their learning, “hear” the student learning will be powerful” (John Hattie, personal communication, July 24, 2016).
