<< Objectives >>Through the implementation of the project, we want to contribute to the rehabilitation of the degraded wetland areas of Inselszentmiklós and the Samosudvar lagoon. We want to educate the wider community about the importance of the marshes and the methods of cleaning the water in the marsh islands. We would like to implement and disseminate pedagogical innovations through the use of extended classroom, 3D, AR education. We want to introduce our students to the possibilities of 3D design.<< Implementation >>During the programme we will hold two Forest School sessions. During the Forest School and the two Wetland Action Weeks, we will create hundreds of metres of wetland islands in Szigetszentmiklós and Szamosudvari. For interested students, we will offer 3D design training, where we will also create 3D models of the marsh habitat. We will collect folk songs related to marsh life and fish life. We will make 3D printed floating footprints, which will be exhibited in several places.<< Results >>We educate our environment about the importance of floating marshes. We can contribute to the rehabilitation of the river sections concerned and thus help to protect our environment. Our pedagogical practice will be extended by the possibilities offered by gamification, project methodology, 3d pedagogy and AR technology. We are succeeding in spreading our natural method of purifying living water.
