Student Interaction The students group together based on their self-esteem and separate if one of the student’s self-esteem changes from a collision with a bully as seen in Figure 1.

Bully Interaction When a bully collides with a student, that student’s self-esteem goes down by one. The bully can lower the students’ self-esteem to the point where the student drops out of school. The bully was also programmed “to smell” (in StarLogo Talk) out the students with low self-esteem, which in the model is students with a self-esteem between 30 to 40. Figure 2 shows the smell block from StarLogo.
Figure 2 Smell Block
The bully on its way to smelling students with low self-esteem could collide with a student with a higher self-esteem, and that student’s self-esteem would go down by .75 as seen in Figure 3.
Figure 3 Collision Block
When a bully collides into a student, the student’s self-esteem goes down and the bully says “hit”. Figure 4 shows the bully saying “hit”.
Bystander Interaction The bystander model shows how the bystander walks around the playground not interacting while the bully goes around lowering the student’s self-esteem.
Figure 4 Starlogo Spaceland
Self-esteem The model starts with 36 students with a low self-esteem of 40, 122 students with a high self-esteem of 60 and 5 bullies with self-esteem of 35. The bystander does not have a self-esteem value.
