The Astronomical Society Tycho Brahe (ASTB) is acting to popularize astronomy, arouse and stimulate an interest in schoolchildren and the general public. School activities are today largely limited to middle and lower secondary school. The aim now is to develop the activity to more distinctly include high school. ASTB has initiated collaboration with Malmö University, among other things, via displays at the observatory for students at the teacher-training programme. At the same time, the issue of educational development in schools is debated as an important field of the future, in particular when linked to various digital tools.
