(ICT) Feedback is an automatic response from a computer, which may take the form of text, image, audio, video or any combination of these, to a learner's input. Input from the learner may take various forms, e.g. (i) clicking with the mouse to select an answer in a multiple-choice exercise, (ii) typing an answer at the computer keyboard, or (iii) speaking an answer into a microphone. Feedback in interactive language learning materials should go beyond a "boing" (wrong) or "applause" (right) or "try again" message and attempt to mimic the "live" situation when using the language results in either a response from the other person or an action showing that the language used was appropriate. Feedback is often described as intrinsic (implicit) or extrinsic (explicit). See Section 7.2 , Module 1.1, headed Feedback, and Section 8, Module 2.5, headed How to factor feedback into your authoring, on the distinction between intrinsic feedback and extrinsic feedback
