Our Research

The National Science Foundation (NSF) grant that produced the DiALoG Tool and all accompanying products is titled Diagnosing the Argumentation Levels of Groups (DiALoG): A Digital Formative Assessment Tool to Support Oral Argumentation in Middle School Science Classrooms (Award Number: 1621441). 

Our research addressed two specific research questions: (1) How can DiALoG be refined to provide a formative assessment tool for oral argumentation that is reliable, practical, and useful in middle school classrooms?; and (2) How does the use of DiALoG affect teacher formative assessment practices around evidence-based argumentation, when implementing science units designed to support oral argumentation?
