The monograph "Virtual Co-Teaching as a Part of Innovative Methods for the 21st Century" is the final research report of the whole project and places virtual co-teaching in the context of other innovative methods for quality and modern teaching in the 21st century. Our goal has always been to provide educators and schools not only with a theoretical perspective on the issue, but also with very concrete and practical guidelines and recommendations for the successful integration of virtual co-teaching into the classroom.
