Abstract

A remote tutoring system of algebra, especially for the factorization of polynomials, is described. The system is aimed at improving the calculating ability of students aged between fifteen and seventeen in Kosen (Colleges of Technology in Japan), and serves each student as an effective training opportunity in the field of factorizing polynomials through the well-organized Kosen computer network. The system receives string data sent by the students, determines if the final expression is fully factorized, finds errors in intermediate expressions, and tells the students of the completeness of the factorization and positions of the errors in the given expressions, if they exist. The system consists of a WWW (World Wide
