It is not possible to make progress in an environment of violence. All kinds of violence cause the interruption of the most basic needs such as peace, security and belonging in the society, and at the same time prevent the potential of individuals from being revealed. Peer bullying is the name of violence in schools where educational activities are carried out. It is not possible to achieve the targeted gains in educational institutions where peer bullying is common. In order to end peer bullying in our institution, the Erasmus+ project named "Happy Schools" was written. With this eTwinning project, we aim to share the training we have received with other institutions, to acquire and develop new ideas, and to train our students on peer bullying and to establish a zero tolerance understanding of violence. Within the scope of our project, we aim to develop the skills of empathizing and exhibiting positive behaviors, especially through the implementation of drama and group activities.
