Learning linear equation solving algorithm and its steps in intelligent learning environment

Abstract

T-algebra is an interactive learning environment for step-by-step solving algebra problems, including linear equations. A step in T-algebra combines conversion by rules with entering of the result. The rules, which correspond to the steps of school algorithms, give the program information about the student's intentions and enable the program to check the knowledge of the student, to understand the mistakes and give feedback. T-algebra is intended to help learning solution algorithms and their steps with designed rules. This article describes the rules designed for linear equation solving in T-algebra. © Springer-Verlag Berlin Heidelberg 2006.
