Giovanni Artico


I'm teaching math in high school since 1972. I had a good expertise in computer programming, and since 1996 I focused on the production of free software for teaching via the Internet: the main products, freely accessible by anyone, are these:

  • EASYpTEST: for the production and delivery of tests via Internet, particularly oriented to math and to the authomatic correction of answers.
  • EASYpMATH: training via the Internet in math, where teachers can post sequences of exercises and the pupils solve them while the computer monitors every step toward the solution and says if it is correct, whatever is the path followed by the solver.
  • EASYpEDIT: from an expression written in line, with a syntax like Derive, creates pure HTML code that inserted into a web page displays the expression in the usual format (MathML was not available when this was created)
  • Geometriagon: a growing collection of geometric construction problems, solvable interactively by ruler and compass; the main goal is to improve the skills in geometry of the solvers, but the problems could be a useful testbed also for analytic geometry, trigonometry or complex algebra
I was active member of a research group in didactics of mathematics at the university of Padova, where I also delivered lectures in didactics to postgraduate math teachers.

Since 1994 I'm active member of CRDM, an association of math teachers born in 1968: it publishes a monthly journal, named "L'insegnamento della matematica e delle scienze integrate", that has a version for elemtary school and another for high school; every year it organizes a four days national seminar; it has a library of around 10000 science books and many collections of math and physics journals, freely accessible by the teachers: a complete catalog of the library is online. It also organizes courses for math teachers, mainly on the use of new technology: many of the members are involved in this activity all over the country. At present my main activity is the online publication of the past 40 years of our journal, hopefully available at the end of this year, and besides this a column on geometry problems for the journal.

From 1998 to 2004 I held also a collaborative project of the ministry of education named 'Abracadabri', focused on the translation by students into european languages of modern and ancient math texts and the publication as web pages.
