Teachers take part in the formal process of curriculum planning through codesign activities to develop dynamic and innovative curricula. Since toolkits and best practices for facilitating curriculum codesign are not well understood and documented in the literature, the presented case study fills this gap by bringing together eight teachers with the aim of developing a nature-inspired curriculum for middle school students centred on the novel concept of fractal patterns. In this article, we discuss the creation of an online toolkit to facilitate curriculum codesign. The toolkit includes a verb bank, state learning standards, images of fractals, and ‘What-If’ Cards, allowing teachers to engage in an open-ended, collaborative exploration to draft a range of classroom activities and lessons. We describe a case study, with two sessions, where teachers codesigned drafts of nature-inspired fractal patterns curricula for middle school students. Qualitative analysis of these drafts suggests that various curricular possibilities can be developed within a novel theme when the toolkit is used in an open-ended format with experienced educators. The article ends on key lessons for the design and use of toolkits in future curricular codesign efforts.
"We want our students to think about key concepts like scale, time, balance, and local geography and all the relationships that are found within these things. And hopefully, we can connect these key learning concepts to learning outcomes and standards and objectives we have set for ourselves, reflecting on key concepts, navigating decision making, researching the Ohio State wilderness, our ecosystem, and trying, constructing, describing, and interpreting practice through co-creation. And all of this will happen through an exhibition that is also again, student-led and created. It is not just an exhibition, but a full festival of events. It is a fractal festival."
