W² is an internet-based program that provides individual instruction in English writing, designed with the aim of helping students to improve their English writing skills in a short period of time. After a student submits a first draft on a given topic, the teacher provides comments, covering grammar, spelling, sentence structure, and organization. The student improves his/her work based on these comments and submits the final draft. The teacher evaluates and sends detailed feedback on the final draft. Students will finish one essay in two sessions.
