Teachers’ meanings for the substitution principle
Page: 801
Structure sense is foundational to mathematical thinking. This report explores high school math teachers’ meanings for the substitution principle, a sub-category of structure sense that research previously identified as sources of difficulty for students. A focus on meanings reflects our belief that teachers’ meanings directly impact the mathematical meanings students develop. We suggest ways of thinking that could lead to various response types as a resource for teacher educators to design professional development targeting improved structure sense for teachers.
