T-Algebra: Adding Input Stage to Rule-Based Interface for Expression Manipulation
Issakova, Marina; Lepp, Dmitri; Prank, Rein
International Journal for Technology in Mathematics Education, v13 n2 p89-96 2006
T-algebra is a project for creating an interactive learning environment for expression manipulation tasks of elementary algebra. Our main didactical principle has been that all the necessary decisions and calculations at each solution step should be made by the student, and the program should be able to understand the mistakes. This paper describes the design of our Action-Object-Input dialogue and different input modes as an instrument to communicate three natural attributes of the steps: choice of conversion rule, operands and result. (Contains 8 figures.)
