First Stage: Bullying Prevention The goal of this stage is to change the social structure of the class. It is necessary to dismantle the existing bullying structure and create a new one based on collective activities and the establishment of new behavioral rules. The educator needs to either redirect (or replace) the class leader, activate leadership qualities in potential "bystanders," assign different responsibilities among the teenagers, and separate potential victims from bullies into different microgroups. Collective discussions and action reviews work well at this stage.

Developing the Group A socially valuable goal for their future life is set for the students, future development perspectives are defined, and a group of the most interested students is selected.

Second Stage: Bullying Prevention This stage involves maintaining the newly established structure with new leaders and preventing negative changes. As tasks are completed, collective activities should become more complex (for example, if the first stage involves finding interesting examples of global school festivals and preparing stories and presentations about them, with photos and participant reviews, the second stage might involve developing their own scenario). Creativity should be a group activity, not an individual one. Role-playing games and team-building methods (e.g., training games) work well at this stage.

Developing the Group At this stage, the influence of the active group in the class increases, which not only supports the educator but is also ready to exert influence on the group itself. This is the transition to self-management, during which relationships of mutual assistance, cooperation, and mutual learning are formed.

Third Stage: Bullying Prevention At this stage, formal and informal structures of the group become closer, and interaction with other groups develops, which in turn increases the students' awareness of the importance of group unity. Collective creative activities continue, and the results can now be demonstrated to other groups. It is the teacher's task to provide the class with the opportunity to share their experience, organize a training session for another class, or share their achievements.

Developing the Group During this period, moral development occurs through collective activities, and the goals of these activities become significant for most students in the class. At this stage, an element of competition can be added to the collective creative activities.
