<< Background >>The idea to create the Young Students as Critical Science Detectives project emerged from a number of Erasmus+ experimentations with open schooling and open science schooling that have shown difficulties for many schools and science teachers when trying to implement the openScience schooling (OSS) methodology. The OSS methodology assumes to increase students’ engagement in science compared to a more traditional approach to science teaching. The Young Students as Critical Science Detectives project aims to address this issue and creating a new open science schooling approaches that is more practically implementable for schools and science teachers in typical secondary schools. In other words, creating an open science schooling that could be integrated in the normal science education or added to normal science education without the need to change the curricula fundamentally, and furthermore, be sufficiently flexible to be implemented in different ways according to the schools’ capacity and resources.<< Objectives >>The Young Students as Critical Science Detectives project aims to create a new open science schooling approaches that is more practically implementable for schools and science teachers in typical secondary schools. This through a Partnership with various competent school and knowledge partners across the EU. Therefore, the project aims to create an open science schooling approach based on the narrative form of classic detectives work in combination with science in order to make science learning more attractive and interesting to young students. The main goal of the project is therefore to create a model of Young Students as Critical Science Detectives attractive to schools and science teachers from across Europe. In addition, another goal is to produce an informative video about students' work with and perceptions of Open Science Schooling as young students as critical science detectives.<< Implementation >>The various project partners have had different roles in the project implementation; Absalon University College was lead on creating the Science Detectives Model, University of Eastern Finland was lead on the dissemination, Universitat Politècnica de Catalunya was lead on Web and media and WwEU was lead on the Policy Paper. Overall, the knowledge and quality assurance partners supported the practice partners in order to insure the implementation of the various phases of the project. A communication and document storage platform was created and online meetings was organized in order to insure project progress. However, the implementation of the project was largely driven by the practice partners and their student teams. Most important the student teams acted as key actors in the project chapters, creating all relevant practical experience in collaboration with science resources in the community, co-created many process outcomes and important parts of the final outcomes and shared their own videos with the partnership and therefore played a major role in the ‘I am a science detective – R U?’ Video.<< Results >>The Young Students as Critical Science Detectives project have produced a number of results. Firstly, the new Critical Science Detective Model have been created; it is guidance collection for secondary schools and their science teachers on how to easily integrate the critical science detectives method in the science curricula. Secondly, a 28 minutes ‘I am a scicence dectetive – R U?’ Video were produced. The video contribute with valuable experience and impressions from the students on open sciences schooling and sciences missions, and documents how the student teams’ developed new images of and engagement in science and science learning along the project duration and the many activities they were involved in. Furthermore, A theoretical paper have been produced discussing state of the art of Open Science Schooling from the point of view of lessons learned in the Critical Science Detectives project. Finally, a 38 pages illustrated PDF policy paper with a number of recommendations regarding Open Science Schooling have been created. The policy paper communicates important challenges linked to the innovation of traditional science learning largely based on contributions from the Young Students as Critical Science Detectives project.enstående
