Educative curricula support teacher learning as well as the learning of students. High quality educative curricula contain features that help teachers customize learning opportunities and environments in ways that meet the needs of their learners. Designing these features requires expertise related to subject matter content, pedagogy, teacher and student learning, and instructional design. In other words, it requires interdisciplinary team work -which is notoriously challenging. To understand and support collaborative interdisciplinary design processes, a retrospective case study was conducted on interdisciplinary design team work that yielded a high quality educative curriculum for inquiry-based science learning. Design documents and transcripts of interviews with six designers (a cognitive psychologist, a practising physicist, and four science educators) were analyzed to identify their contributions during the phases of analysis, development, and evaluation to create educative features for developing pedagogical content knowledge (PCK). Findings articulate specific educative features that can contribute to supporting PCK and thereby supporting instructional performance. Findings also reveal the proactive and reactive nature of designer contributions, describing different ways in which designers provide specialized inputs from a disciplinary perspective. Further, this study shows how designer contributions intermeshed, with contributions from one discipline shaping the work of colleagues, and thereby coordinating varied inputs to yield coherent educative materials. In addition, theoretical insights and recommendations for research on the nature of collaborative interdisciplinary design processes and implications for practice are given for supporting designers working in interdisciplinary teams to create educative curriculum materials for teacher (and student) learning.

School-based citizen-science can be a powerful means to engage youth in environmental education, yet developing robust science curricula around citizen-science activities is tremendously challenging. Prior research provides limited examples and very little guidance for curriculum designers. To support the designers of school-based citizen-science curricula, this research article presents a participant-observation case study of designer thinking and processes in creating and integrating in-class curriculum with citizen-science fieldwork. Interviews, observations, and documents of designer work aimed at supporting middle school students' learning of climate change were analysed to gain insight into designer thinking, challenges, and resolutions. Findings indicate how designer work evolved through various measures, including appraisal by external advisors, inspiring examples, surveys of teachers' implementations, and written pre-post assessments of student learning throughout the phases of analysis, development, and evaluation of the curriculum. Four key considerations for designing school-based citizen-science curricula emerged from the data: creating the learning environment around the fieldwork; tackling concerns about data quality and utility; making scientist-designed fieldwork engaging to students; and balancing scientific and educational goals. These considerations are discussed in light of relevant literature, and educational implications for design and research are presented.

Around the globe, science education during compulsory schooling is envisioned for all learners regardless of their educational and career aspirations, including learners bound to the workforce upon secondary school completion. Yet, a major barrier in attaining this vision is low learner participation in secondary school science. Because curricula play a major role in shaping enacted learning, this study investigated how designers developed a high school physics curriculum with positive learning outcomes in learners with varied inclinations. Qualitative analysis of documents and semistructured interviews with the designers focused on the curriculum in different stages-from designers' ideas about learning goals to their vision for enactment to the printed materials-and on the design processes that brought them to fruition. This revealed designers' emphases on fostering workplace connections via learning goals and activities, and printed supports. The curriculum supported workplace-inspired, hands-on design-and-build projects, developed to address deeply a limited set of standards aligned learning goals. The curriculum also supported learners' interactions with relevant workplace professionals. To create these features, the designers reviewed other curricula to develop vision and printed supports, tested activities internally to assess content coverage, surveyed states in the USA receiving federal school-to-work grants and reviewed occupational information to choose unit topics and career contexts, and visited actual workplaces to learn about authentic praxis. Based on the worked example, this paper offers guidelines for designing work-based science curriculum products and processes that can serve the work of other designers, as well as recommendations for research serving designers and policymakers.
