Abstract
This study analyses ways of using violence in the classroom by teachers to students (VPA) and students to teachers (VAP), according to the students` perception of secondary obligatory education (ESO). The sample is composed of 4943 adolescents whose ages range from 12 to 17 years old. The questionnaire of school violence (CUVE3-ESO) used in our study has a Cronbach`s alpha of .90 (high reliability), and the split-halves method has an alpha of .82 (items VPA) and .84 (items VAP), confirming that the instrument has high reliability. From factorial analysis was extracted two factors (F1: VPA; F2: VAP) that explain 44.8% of the variance. The results show a similar percentage of violent behavior in both directions (VPA: 18.9%; VAP: 15.9%), being the conducts most used by teachers: the use of ratings as pressure behavior (31%) and preference for certain type of students (29.5%). And being the conducts most used by students: to speak during the class (46.6%) and inadequate behavior (39%).
