In this article, it is argued that processes of co-production can support teachers and students in organizing resources for justice through science learning. Drawing upon a critical justice conceptual framework, critical ethnographic data from one urban middle school classroom during a unit focused on engineering for sustainable communities were analyzed.

Echoing calls to expand environmental education research through design, this study explores the role of design in garden-based education and illustrate its contributions towards practical impact and theoretical insight. Design can explicate and map conjectures about resources, tasks, roles, and other supports for learning and teaching then, in turn, can be teste to illuminate how these supports operate together. Design, as such, focuses holistically on examining systems of activity.

Includes eight separate lesson plans to help integrate the primary literature into the classroom.

What ideas do students have about small particles of matter? The Two Cups of Liquid task is intended to elicit preservice teachers’ CKT related to students’ ideas about the small particle model (SPM) for matter. The first part of the task asks preservice teachers to articulate their own understanding about why two cups containing different volumes of liquid might have the same mass, while the second examines how elementary students might respond.

What does it mean to help students develop a small particle model of matter? The Mystery Bubble task is intended to elicit preservice teachers’ CKT related to students’ ideas about the small particle model (SPM) for matter, particularly the idea of empty space between the particles. The task presents a phenomenon in which combining ethanol and water results in a mixture that occupies less space than the combined volume of each.
