professional vision, pre-service teacher´s education, lesson observation, video

The article presents the experience with the use of video in the training of future teachers and the professional development of in-service teachers of science subjects. It focuses mainly on a suitable way of analysing video recordings through web tools. The analysis, as well as the reason for taking a video recording of the lesson, is divided according to whether it is an evaluation of another teacher or self-evaluation. In the first case, the analysis is used mainly in the education of pre-service teachers, in the second case for the professional development of in-service teachers from partner schools.
