Prezi is a free, visual presentation tool. It has become very popular over the recent years, and many have already replaced their Powerpoints with Prezi-presentations, because the tool gives some new visual possibilities and is easy to use.
In the monologic form of teaching, Prezi can be used by the teacher tointroduce to a topic, and to present the main concepts of the subject to the class.
Within the polyphonic form of teaching You can let students collaborate on the development of a Prezi — you can, for example, allow groups of students work simultaneously with different parts in a Prezi-presentation, and turn it into a kind of common ' mind-map ' on a topic. The tool can also be used for students ' presentations – it will for many be motivating pupils to be able to make a nice, visual presentation, and since the tool is intuitive and easy to use, the vast majority of learners will be able to use it after a short introduction.
