En primer lugar enhorabuena por las web page. Es una prueba practica de las posibilidades de aplicacion de los computadores a la educacion. They open a fantastic world, the use of internet in the classrooms is fascinating and that computers offer new and important challenges to the educators. We are accumulating links to Interactive Web-based computer systems of educational purpose in the home page of Online Exercises Project . So far we have located very few, and have even less data on actual usage.
