"The project is a cooperation for innovation and exchange of good practices among4 European schools from Poland (the coordinator), Macedonia, Turkey and Romania. The project duration is 24 months starting from 1 October 2018. The participants of the project are students aged 15-18 attending comprehensive or vocational schools.The project title is: ""The mystery lies in QRs- coding and decoding in education."" The objective is to work out interesting activities with the help of QR codes during different subject lessons. In these activities QR codes are combined with Project-Based Learning and Game-Based Learning. The use of QR codes involves the students’ use of their smartphones in order to read the encoded message. The message can be a text, a picture, a recording or a video. The expected result of the project is students’ greater engagement in the classroom activities and better academic performance. What is more, students make use of their phones during the lessons, which makes mobile phones useful educational gadgets. The method is deeply imbedded in the digital era because it involves creating videos and podcasts by students themselves.This aspect of creating educational content and not just being lectured on it has an extremely positive impact on students’ development based on freedom of choice in content and method.Work on the project in the initial phase is to acquaint the teachers from the participating schools with the technical aspects of this tool. It turns out that very few teachers from all the partner schools know what QR codes are, not to mention Augmented Reality (Aurasma) which is a more developed version of QR codes. The aim of the project is to adapt the solutions that have been used in commerce to the needs in education and measure their impact on the teaching process. The project includes many activities, some of which are completed during 3 short-term exchanges of pupils. The core is to test QR codes in many subject classes and do projects based on them. Every exchange will be devoted to difeerent types of activities. In Turkey students will take part in The Treasure Hunt Game and other activities based on Game-Based Learning. The Romanian exchange will concentrate on Project-Based Learning and will offer the students a variety of projects connected with the professions taught in the Colegiul Tehnic in Braila. The third exchange will take place in Poland where all the participating teachers and students will experiment with Aurasma – the tool of the future. During the project students from all the partner schools will have an opportunity to learn cultural background of the partners' countries and practise linguistic skills.The project touches upon the tools which are complete novelties to all the schools taking part in the project. The dissemination activities and events will spread the good practice among teachers outside the participating schools and encourage them to be more technology-friendly. The results will be placed in The Erasmus+ Results Platform to inspire teachers from the whole Europe to use technology in the classroom on a daily basis."
