This paper presents the research behind the formulation of a new didaktik model on waste and material resources in preschool. The research was part of an extensive collaborative R&D programme, involving close to 300 preschool teachers/managers and researchers, to build systematic knowledge on what may characterize teaching in preschool based on scientific grounds and proven experience.

The article is guided by the question What can characterise the “what”, “how”, and “why” questions of teaching from the standpoint of a post-structurally and didaktically informed teaching arrangement in the preschool? The substudy is based on material consisting of 251 documents, including co-plans, videos (5.5 hours) and photo documentation, as well as co-assessment.

This article is based on a partial study of an R&D programme with various theory-informed teaching arrangements aimed at describing and further developing knowledge of what characterizes preschool teaching.

This article develops knowledge of what can characterize such teaching, particularly regarding goal and motive, content, and teaching actions. The material was generated in 2018–2019 in collaboration with 42 preschool departments in Sweden.

The purpose of the article is to develop knowledge of what can characterize music teaching using digital technology as a tool in the preschool from a didaktik perspective. In a research and development programme involving 19 preschools/departments, preschool teachers co-planned, conducted, and co-evaluated music teaching.

The paper presents a review process of Didaktik and curriculum theories, one that suggests that a German Bildung Didaktik approach seems to be suitable ground for the development of a critical-democratic Didaktik in preschool.

This themed issue presents the results of a collaborative conceptual replication study based on a research and development (R&D) programme entitled “Multivocal teaching in preschools”. The issue is practically and theoretically positioned in a Continental–Nordic didaktik tradition, specifically a critical-reflective one.

Succeskriteriet for en vellykket skolestart er, at alle børn oplever trivsel i skolen og finder motivation for at deltage engageret i skolens aktiviteter. Med afsæt i et empirisk studie af 95 kommende skolebørns og 12 dagtilbudspædagogers deltagelse i fem legeværksteder på den lokale skole viser artiklen, hvordan børn i deres møde med skolens forventninger handler, udveksler og tager del i de rammesatte konstruktionslege – og derigennem aktivt skaber relationer og trivsel.
