Aristod The ARISTOD company is a start-up of the Laboratoire d'Informatique de Grenoble (LIG) which develops and distributes software for learning and for mathematics. It has currently two products: epsilonwriter and Aplusix. English
epsilonwriter software Aplusix software
  • epsilonwriter is a Web application for online documents, questionnaires, emails and forums
  • It has been developed in order to facilitate the input and the modification of documents and questionnaires composed of texts and formulas (math, physics, etc.).
  • It uses both buttons and keyboard commands.
  • It shows several interpretations of certain actions in a pop-up
  • It allows inserting images.
  • It contains mathematical tables.
  • It allows doing calculations.
  • Aplusix is a Windows application which helps students to learn algebra
  • It is an highly interactive application
  • Students freely make the calculation steps
  • Aplusix verifies the student's calculations and solutions
  • It is based on a model of algebraic calculations
  • It has been designed at the Laboratoire d'Informatique de Grenoble
  • It is "recognized of pedagogical interest" by the French Ministry of Education
  • Its companions make suggestions and calculation steps.
Current uses of epsilonwriter Uses of Aplusix
  • Document with formulas which can be printed 
  • Emails: write your messages with formulas on the epsilonwriter website, they will be received with the formulas in the body of the message
  • Forums: discuss with formulas in your messages
  • Questionnaires: write easily and quickly questionnaires with multiple choices and open answers, and with explanation appearing at the evaluation time
  • Webpages: write a document or a questionnaire and get a link to put it on your webpages - export your documents as HTML or XHTML webpages. 
  • At school, teachers go to the computer room with their students for exercises sessions
  • At home, students train to improve their skills
  • The training mode allows to have immediate feedback (calculation errors, incorrect solutions)
  • The test mode allows having scores and a self-correction phase with error indications and the possibility to correct them.
The epsilonwriter project The Aplusix project
  • Main envisaged extensions of epsilonwriter:
    • extension of the calculation domain
    • import/export of files in Latex
    • addition of graphics and trees
  • New envisaged uses of epsilonwriter:
    • a local application version 
    • Communication with other applications
The main envisaged extensions of Aplusix are:
  • a tree representation of expressions
  • a graphic module allowing to represent and compare curves associated to expressions
