We are trialling learnosity as a way of assessing oral skills and I have just marked the first TMA. This involves learners responding to various prompts by logging in to the Learnosity website. In the case of my involvement in the materials design, the prompts related to academic English (e.g. giving their responses to an academic text).
It seems to be a useful tool but feedback is quite time consuming as I often need to listen several times.
