Background: The European Union asks for renewed pedagogies in schools according to teaching strategies and necessary competences for the twenty-first century, instead of the often-used transmissive pedagogies. The national Swedish competition in science and technology for grade eight, The Technology Eight, provides an opportunity for teachers to work with instructional strategies in line with suggested pedagogies.

Purpose: To investigate teachers’ and principals’ reflections on the competition in schools.

Sample: Seventeen secondary school teachers and three principals from districts in the south-western part of Sweden participated in the study. All teachers had long experience of the competition, and their classes had reached at least the regional finals during the last year.

Design and methods: Semi-structured interviews were recorded, transcribed verbatim, and then analysed using content analysis. Focus was put on why the teachers decided to participate, how the teachers integrated the competition in their education and roles of the principals.

Results: There were various reasons for participating in the competition. Teachers reported development of twenty-first-century skills such as better cooperation between the students. They also noticed an increased interest in science and technology and how learning in the subjects was stimulated. Furthermore, the teachers found participation in the competition to be positive for them too. They integrated the competition in ordinary education and gained teaching ideas as well as found connections to the curriculum. Participating in the competition seemed to be a tradition in most of the schools. The principals’ role was to facilitate the organisation around the competition and to provide social support.

Conclusions: Participation in a school competition was considered as an instructional strategy with several positive outcomes. Use of this strategy can be supported by earlier suggestions to use pedagogies that are opposite to transmissive methods, enhancing students’ development of important skills for the future.
