The project creates an online collaboration environment for the Erasmus+ project Augmented content, 2021-1-BG01-KA220-SCH-000027925. The project materials from the first project year can be find at the link to the project Old TwinSpace: https://twinspace.etwinning.net/225791/home (we are prividing it here, because we created the project in the old platform and this TwinSpace is no accessible directly from the new one) The project is about to develop new methodology and tools for teaching school subjects by using Augmented content. One of the project objectives is developing the digital competency of teachers and students in the area of creating digital educational resources, accesible with the mobile App, developed by us. This eTwinning project and the project TwinSpace is an online platform for collaboration for the involved schools. Three schools are in the partnership - from Bulgaria, Greece and Turkiye and associated partners from the educational organisations, partners into the Erasmus+ project. One of the project members is eTwinning ambassador and is helping in developing the eTwinning project. Why we started this project? For teachers, to be effective in the digital classroom is one of the keys to raising levels of pupil attainment. The new school reality includes VR, AR and AC. During the project, teachers will be learn how to create unique content linked to the textbooks (AC). TwinSpace (the old and the new one) is a platform for online collaboration and storage for all materials. This project will help teachers for both, distanse and classroom teaching. Three main products will be created within the project: - O1: Web platform for augmented content; O2: Mobile application for augmented content; O3: Video tutorials for creating digital content. The large project dissemination is one of the project aims.
