Abstract

: We wanl lo creale a working 1001 for malhematics leachers and a corresponding learning 1001 for sludenls, namely a graphical simulalor of malhemalical algorilhms (GraSMa). To achieve il we Iry Iwo differenl slralegies. We slarled by annolaling manually lhe original algorilhm wilh inspeclor functions. Now we are lesting a new approach Ihal aims ai aulomalically annolaling lhe original code wilh inspeclor funclions. To achieve Ihis we are developing a language Iranslalor module Ihal enables us lo commenl aulomatically on any code written in Oclave language. The run of lhe annolaled code galed by one of Ihese two ways, records in a XML (eXlensible Markup Language) file everylhing Ihal happened during lhe execution. Subsequentiy, lhe XML file is parsed by a Java applicalion Ihal graphically represenls lhe malhemalic objecls and Iheir behaviour during execulion. The final application will be accessed on-line Ihrough a websile (WebGraSMa) which is currentiy under developmenl. In Ihis paper we reporl and discuss aboul lhe procedures followed and presenl some intermediate results.
