We had an original model that we thought was finished, but when we ran the model, the students were dropping out faster than they were in the bystander model, so we had to rebuild the model from scratch.
Student Interaction When students collide, the program will see if they have the same self-esteem, and if they do, they group together, but not all students group together. They split apart when one of the student’s self-esteem changes from a collision with a bully or frally. It was programmed this way to be more realistic. Most students on a playground normally hang out with their friends. There are also a few students that walk around by themselves. Also, in this model, if the frally collides with a student and its self-esteem goes up to 65, then that student turns into a frally.
Figure 6 New Frally Procedure
If the bully collides with a student and causes the students’ self-esteem to go down to 30, then that student drops out of school as seen in Figure 7.
Figure 7 Drop Out Procedure
Bully Interaction The way bullies interact in this model is the same way they do in the bystander model. When a bully collides with a student, that students’ self-esteem goes down by one. We also programmed the bully to smell out the students with low self-esteem, which in the model is a student with self-esteem between 30 to 40.
Figure 8 Bully Smell Procedure
The bully on its way to smelling students with low self-esteem could collide a student with higher self-esteem, and that student’s self-esteem would go down by .75. If a frally collides with a bully, then the bully’s self-esteem would go up by .125,and if the frally gets the bully’s self-esteem to go up to 40, then the bully turns into a student.
Figure 9 New Student Procedure
Frally Interaction Frallies seek out students with lower self-esteem as seen in Figure 10 below. When a bully collides with a student with high self-esteem, then that student’s self-esteem goes down by .75. When a bully collides with a student with low self-esteem, then that student’s self-esteem goes down by 1. When a frally collides with a student with self-esteem, then that student’s self-esteem goes up by .125. If a frally collides with a student with low self-esteem, then that student’s self-esteem goes up by .25.

Self-Esteem This model starts with 36 students a low self-esteem of 40, 122 students with a high self-esteem of 60 and 5 bullies with self-esteem of 35. The self-esteem of these agents will go up and down based on the agents that collide with them. The frally has a fixed self-esteem of 65.
