TMA Technology for Mathematical Argumentation

The TMA project aims to create mathematical computation tools that enable students to learn and demonstrate algebraic reasoning prior to learning about formal algebraic proofs. The tools are created in collaboration with leading mathematics educators. They are being developed and tested using our tablet-based Classroom Learning Partner (CLP) software and in conjunction with our NSF-funded project, INK-12: Teaching and Learning Using Interactive Ink Inscriptions in K-12. TMA makes use of CLP's ability to support the creation and manipulation of visual representations, in particular those used in multiplication and division; the replay of students’ interactions in creating the representations; and the sharing and display of student work as the basis for class discussion.
