The collective correction is an crucial element in students' learning. To acknowledge skills linked to the National Education's programs, the collective correction can be employed as different educational devices that can attract student's interest in learning and in the progression of learning. The bibliographic study has oriented my study to the « co-correction » as a duo. Through five binomials, I could make deductions about results which has a positive effect on maintaining students in learning, but also brings an interest in the studied documents. The social contribution is a crucial point in this study because it makes interactions possible between students and removing the idea of the correction as an element reserved to teachers. This device gives the teacher the ability to be involved and to make different interventions by taking every precaution in the classroom and assist in students' working methods. Thus, having two students correct their own work promotes their active posture. That allows to blur the negative idea that students have about making mistakes in order to tend to a reassuring climate, a motivating working environment and a personal satisfaction through each student's involvement.
