The aim of this work is to train students to work independently (flipped classroom), peer learning and motivation for critical thinking. Students at home watching the lesson as text and video on the Moodle platform. Share their experiences with their friends so they work together or through Skype. At a school they confirmed their knowledge and work assignments. At home, they do a test in Moodle as a preparation for a test in school that will also work in Moodle.
