Here, the implementation of a technology (clicker)-supported classroom feedback system is described which provides students with three different levels of feedback: First, a direct computerized quantitative feedback; second, a dialogical external feedback from peers; and third, a class-wide qualitative external feedback from the teacher. This easy to set-up three-stage classroom feedback system which enables the application of several principles of good feedback practice triggered measurable learner and teacher self-regulation thereby improving the quality of learning and teaching.
