EMDR for Eye Movement Desensitization and Repro-cessing developed since 1989 by F. Shapiro has demonstrated its effectiveness in the treatment of Post Traumatic Stress Disorder (PTSD). In Science of Education, no study has been previously deve-loped in the application of EMDR protocols. The purpose of this article is to demonstrate the relevance and effectiveness of EMDR in supporting cognitive and emotional remediation of students in Master 1, with respect to mathematics, preparing Schools Teacher contest. The first encounters with the students revealed, through their discourse, an aversion to mathematics linked to one or more particularly painful experiences in a learning situation. Mathema-tics may cause anguish, sometimes tinged beliefs such as “I’ll never be able to. . . I am very bad at math”. This represents even an insur-mountable obstacle in the professional life of some.Methods. – Nearly 170 students in Master 1 “Professor of the Schools” registered on the ESPE (College of the Teaching profession and Education) were asked about their relation to mathematics, both in their emotions as their self-efficacy. Among those who sug-gested a traumatic memory in a learning situation in mathematics, forty were selected and divided into two groups. The control group received two hours of information about relaxation techniques that could be used before mathematics. The other group benefited of the EMDR treatment according to the standard protocol in eight phases.Results. – The results showed that students who received EMDR treatment experienced after treatment and one month later, a signi-ficant decline in their negative emotions with mathematics and an increase in the strength of their self-efficacy, unlike the control group.Discussion. – EMDR demonstrates its effectiveness in reproces-sing beliefs and emotions of students with respect to mathematics and opens ways of research in Educational Sciences. So, it will be necessary, from the principle of alternated bilateral stimulation, to develop specific protocols for the struggling students, to measure the effects in the long term and develop them in a group situation.
