The motivation behind the M-Lang project is the need to upgrade the professional skills of teaching staff and improve learning outcomes by means of state-of-the art mobile enriched technologies and Open Educational Resources (OER). In a European landscape in which the imperative is for better qualified teachers (The New Skills for New Jobs initiative; ET2020 Agenda) and the emphasis is on rethinking the nature of learning and teaching in Europe (Opening Up Education initiative; Rethinking Education initiative) through innovative teaching/learning approaches and OER, the M-Lang consortium is situated in the triangle of innovative educational approaches and OER> mobile and digital technologies> learning/teaching skills. Partners have identified gaps in terms of training of their staff in innovative learning and assessment methods and strive to close these gaps by joining forces in a collaboration built on complementary partner profiles: a Higher Education Institution (HEI) delivering and customizing mobile solutions for learning, two private and one non-profit organisations, and one research centre/HEI specializing in adult education, all located in different countries - Greece, Italy, Norway, Spain and Sweden. The cross-country approach is also cross-sectoral, as partners will involve staff teaching languages and also Social Sciences and Humanities subjects. The means to achieve better qualified staff and better learning outcomes for students is an ICT-based learning and teacher training approach that is supported by mobile devices (smartphones, tablets) and computers. To cater to the reality of all institutions and to meet business imperatives, the technological solution will be very cost-efficient as it is based on a Bring Your Own device (BYOD) concept for both learners and teachers. M-Lang supports the teachers throughout the project by offering hands-on demonstrations of the range of mobile learning applications, and more importantly continuous proactive and reactive teacher training support by experienced team members while the teachers implement the mobile enhanced approach with their learners. The project also gives educational staff the opportunity to join an intensive 5-day joint training course to further develop their skills, by co-creating, negotiating and publishing pedagogical scenarios, activities and tasks - both language specific and across languages - also joined by teachers in Social Sciences and Humanities. Assessment of progress in terms of teaching and learning skills and attitudes will be continuous and based on quality indicators. Freely licensed project results as guidelines for learning and assessment with mobile devices, pedagogical materials for use in class in the form of OER, and a study on progress made on attitudes and skills of both learners and teachers will be produced in GR, FR, IT, NO and SE and disseminated at national and European level. The partnership will organize multiplier events in each country so that its educators and educational policy makers can foster penetration of the approach and to highlight good practice emerging from class interaction. Teachers and learners with disabilities are given special attention as the project financially supports their participation in the teacher training course and the five multiplier events in Europe.
