The aim of this study is to contribute with knowledge from a close teachers’ perspective on how teachers' considerations and choice of digital artefactsfor teaching are related to didactic beliefs that are shaped and changed over time in teacher's professional life. A thematic life history approach is used in combination with a socio-cultural perspective and didactic starting points. Life story interviews with six high school teachers from three Swe-dish schools constitute the empirical material that results in individual life history constructions about digitalization. The participating teachers have what is referred to as digital didactics, which focus on the teachers' competence to make didactic considerations and the choice of digital artefacts according to the needs that exist according to the target group for the teaching, subject content and surrounding envi-ronmental and time aspects. The findings of the study indicate that teachers have prominent didactic beliefs that are the hub for consideration and choice of digital resources. These can be understood as individual but also in a larger collective context. Teachers’ didactic beliefs are motivated by three dimensions, which are the teachers' subject matter, the desire to help the students and the personal satisfaction. The cognitive, historical and physical contexts are constantly changing due to the rapid development of digitalization and the didactic choices have been expanded with more opportunities but also greater chal-lenges. Didactic choices of digital artefacts can be divided into general-di-dactic choices, subject- and program-didactic choices and choices linked to didactic beliefs and experience. The contribution of this study is that teachers' digital didactics is based on teacher's didactic beliefs, which are formed in a historical, cultural and social context that influences the didactic present and the future. A school with digital artefacts is part of an ever-available global digital arena. The study contributes with a new model of an extended didactic triangle that visualizes teachers’ digital didactics where the teacher and the didactic belief are prominent.
