This example of strong student co-determination in SE took place at a large school in Silkeborg, Denmark. In the centre of the school, there was a closed atrium yard which lay unused. A team of teachers teaching 8th grade (four classes) agreed to create a common course for the students, which was about transforming the atrium garden into a sustainability garden. The focus was on UN SDG 15, life on land, which was combined with several of the other UNSDGs. Each class was allocated ¼ of the area of the atrium garden, which they had to agree to develop in terms of form and content. Each individual student came up with ideas, which were subsequently discussed and either accepted or rejected by the rest of the class. Throughout the course, the students had a great deal of responsibility and co-determination; an important part of the task was precisely getting the students to negotiate an agreement in class in relation to the intervention. The role of the teachers in the course was mainly facilitative, ensuring that the students followed a plan and making sure relevant parts of the national curriculum were catered to.
In the process, one of the classes chose to combine UNSDG 15 with UNSDG 6, clean drinking water, and subsequently built a water-collection system for irrigation. Another class combined UNSDG 15 with UNSDG 2, stop hunger — building planter boxes with vegetables. A third class combined UNSDG 15 with UNSDG 3, health and well-being, and built garden furniture that would encourage the other students to spend more time outside.
When the school garden/living room had to be laid out, the students’ input and expertise were included in many ways. In mathematics, they calculated the size and material consumption of planter boxes. In craft and design, they designed and built the planter boxes. Delivery of plant soil was also ordered, which had to be brought into the area. This was physically hard work — perhaps harder than what normally took place in physical education.
During the process, the teachers thus ensured that relevant professional content was included in the teaching. All in all, this meant that the project was extremely meaningful to the students, and they felt great ownership of the process and the finished sustainability garden. The students were proud to be able to harvest their own organic vegetables — something many of them had not experienced before.
The organisation and implementation of the course fits the PACK model (Jónsson & Macdonald, 2021). The students’ interests are the starting point for the learning process, and students and teachers together develop, plan, and implement the course. This contrasts with more conventional teaching, where curriculum and evaluation govern the teaching.
