(Prerequisite: consent of instructor.) The course explores the process of argument necessary for advancing and defending new ideas or explanations of STEM-related phenomena. STEM teachers and school librarians learn the norms for using evidence to construct and defend viable arguments, and to compare and contrast different sources in the process of creating a coherent understanding of phenomena, concepts, or design solutions.
