The ContinueUP project addresses the question how more, and more effective teacher education and training can be offered to teachers across the continuum of initial and continuous teacher education and training. It achieves this by piloting processes and outputs at initial teacher education (ITE) and continuous professional development (CPD) level which on the one hand develop teachers’ capacity to benefit from online training opportunities, and on the other hand reduce barriers to take-up such opportunities. The project establishes a network of ITE and CPD providers that will co-construct and deliver an education and training programme across the continuum of ITE and CPD. The programme consists of an ITE module and a CPD MOOC which are both addressing teachers’ use of digital tools for professional engagement. The delivery of the module will be implemented jointly, allowing student teachers from different countries to study together. Student teachers are then encouraged to continue their learning by following the MOOC. By participating in the ITE module, student teachers will be better prepared to participate in and continue their learning through online and blended learning formats once they enter the profession. In-service teachers will benefit by developing their capacity to engage in more advanced online mobility activities and CPD opportunities. The co-construction process used for the development and delivery of the education and training programme also introduces mobility experiences to teacher educators and trainers, for them to be able to better promote such experiences amongst teachers. The co-construction process also aims to increase the effectiveness and cost-efficiency of developing new teacher education and training programmes. Furthermore, the project will pilot processes that can lead to the formal recognition of teacher CPD MOOCs, gaining valuable insights how to address barriers for the take-up of non-formal online learning formats by teachers.
