Coding online content-informed scaffolding of mathematical thinking

This article describes the Mathematical Mentoring Coding Scheme (MMCS), a coding scheme that identifies indicators relevant to the study of content-informed scaffolding. Content-informed scaffolding refers to the use of subject matter content in ill-defined problem spaces to focus the learner, and provide and fade feedback so that the learner becomes autonomous. It is suggested that the MMCS could also double as a rubric for instruction in content-informed scaffolding. Two case examples of preservice teachers' scaffolding of elementary students' problem solving serve as illustrations.
