We present lessons learned from an ongoing attempt to conceptualize, develop, and refine a way for teachers to gather formative assessment evidence about classroom argumentation as it happens. The system—named DiALoG (Diagnosing Argumentation Levels of Groups)—includes a digital scoring tool that allows teachers to assess oral classroom argumentation across two primary dimensions: one to capture the Intrapersonal, discipline-specific features of scientific arguments, and another to capture the Interpersonal, group regulatory features of argumentation as a dynamic social act.

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.

What is a scientific explanation and how can we support students in explaining changes in matter? The Fizzy Antacid task is intended to elicit and develop preservice teachers’ CKT related to students’ scientific explanations of changes in matter. The first part of the task asks preservice teachers to develop their own explanations and engage in scientific argumentation, while considering how elementary students might explain the Fizzy Antacid phenomenon.
