1- Challenge : 

 40 % of the pupils are characterized by an aggressive behavior that leads them to practice   violence in all its forms , according to the results of the study prepared by the laboratory on   violence in the school environment , Personally , I suffered from the phenomenon of violence by   my colleagues in the three educational phases and even from my teachers , even though I was a   superior student . So violence in our country schools is representing an injustice which is   affecting negatively on the children 's physical and mental health , academic results and   potentials development .   So clearly the challenge I made is working on limiting and reducing the amount of violence in our   educational institutions through social initiative directed by young volunteers . 

 2- Selection : 

 Violence in schools represents a wicked problem which has various causes and reasons , so one   of the significant missions to find an efficient solution to this injustice is to address the root   causes behind this problem , automatically , trying to find the causes of violence in our schools   was my first stage toward solving the challenge I made . So I have been chosen visualisation as a   tool to get out the real causes behind this injustice . 

 3- Application : 

 The most touched categories by the effects of violence in schools are constantly : children ,   teachers and parents . For that , I have used visualisation with parents and teachers . More   specifically I have created a document which contains a tree that has empty columns which   represent places to be filled out with the reasons that parents and teachers see that it is the   root causes of violence . Practically I have shared that big paper of violence causes filling with my   parents and I asked them to share it with their friends , also I had visited all the schools I studied   in and gave that visualisation tool to all the teachers . 

 4- Insight : 

 After collecting all the documents I have discovered many root causes behind the injustice I was   addressing . I have known that social media and video games represent a big role in this   phenomenon , also each child personality is so important while addressing an efficient planning   for the solution I will make . Finally all the information I have been gathered from that process   helped me a lot in choosing nonviolent education workshops in schools as an appropriate   solution . 

 5- Approach : 

 Honestly I have gained many important knowledge about the challenge I made thank to   visualization tool , but if I would like to change something during that process is to ask the   category of people which worked on helping me to work in a group and not individually as I   asked them , because that will shorten the whole process since I will have a small number of   common works and then gain more time .
