The aim of this reflective paper is to analyse how Finnish teachers are encouraged to adopt the use of information and communication technology (ICT) in teaching and learning. The paper is based on our research group experiences. First, a Finnish education context and a Finnish school model are introduced. Second, different approaches, like strategy-based development and pre- and in-service teacher education approaches in the context of ICT use, are discussed. Finally, the outcomes of 25 years of development of ICT use in education are briefly evaluated. Most examples are presented in the context of science education.
