MLEARN is an international project that aims to integrate the use of handheld mobile technologies as a recognized learning tool in schools. The project will provide training to teachers on how to use mobile devices confidently and effectively in the classroom to transform teaching and learning across all subject areas. Teachers will be challenged to think creatively about mobile learning and develop their skills in using new technologies and ideas within the school curriculum. The objectives of the MLEARN project are to embed mobile technologies within teacher training programs, pilot the training with teachers in various schools, and enable teachers to use their new skills and competencies through school-based projects and activities.
