Work in progress: iComb Project - a mathematical widget for teaching and learning combinatorics through exercises

This paper presents iComb, a widget for teaching and learning combinatorics. The project was inspired by the idea of bringing up mathematical domains to the changing trend named as Web 2.0 and encouraging the development of a family of ¿math widgets¿ to improve the mathematical education scenario. The paper's contribution are: (i) a Web-based application that is tailored to learn and teach combinatorics, an important issue for K12 and CSTE students; (ii) an interactive widget that can enrich Web sites and e-communities; (iii) an e-LM (e-learning module) with automatic assessment resources.
