The document discusses using Moodle, a free virtual learning environment, for collaborative tasks such as peer review and coevaluation. Moodle allows teachers to create online learning sites and features autocorrecting quizzes to save teachers time on grading. An example task has students act as journalists and review each other's work, with teachers able to review student evaluations and adjust grades. The conclusion notes that Moodle autocorrects work, criteria are clear for students, tasks can include files or pictures, and coevaluation reinforces learning as students review peers' work.
