However, the current teacher education do not necessarily provide pre-service teachers with these skills. For this purpose more long-term research and development work is needed. The goal of this project is to provide teacher education information and tools for being able to provide their pre-service teachers with better abilities and readiness to work as a teacher in society today and in the future. For this purpose the aim is to study the structure and development of pre-service teachers’ 21st century skills.
