We want our students to work in teams for creating online dictionary about computer hardware terms. Online dictionary will contain English (as main language) and Turkish, Catalan and Spanish words equivalences, and definitions in each language. For this purpose we will perform collaborative tasks using web 2.0 technologies. In addition to arranging its content, students will code and design the online dictionary. The dictionary will be coded in XML language, and an interface will be create to look for words in it.
