Writing center tutors know that improving writing skills requires sustained effort over a long period of time. They also know that motivation - the drive to actively invest in sustained effort toward a goal- is essential for writing improvement. However, a tutor may not work with the same student more than once, so tutorials often need to focus on what can be done in a single 30- to 60-minute conference. Further, although tutors are likely to attempt to motivate students to invest time and effort in improving their writing, when writers leave the writing center, tutors' influence might end with the conference. Therefore, tutors must work to develop and maintain students' motivation to participate actively during the brief time they are collaborating in writing center conferences.
