Study on school violence shows the secondary school environment compels learners to be armed
2015-01-26

The secondary school environment apparently compels learners to come to school armed. This is according to a study done by Dr Lynette Jacobs, a lecturer at the School of Education Studies at the University of the Free State.

In her study, Dr Jacobs found that learners from more affluent schools carry noticeably more weapons than learners in less affluent schools. Learners in the lower grades of secondary schools also use and carry more weapons than learners in the higher grades.

Dr Jacobs says while many reasons for school violence can be noted, such as to forcibly take the victims money and food, racial differences, religious differences, as well as the immigrant status of one of the parties involved, these were reasons indicated by less than 10% of the participants in the study.

“There is no single explanation for the threat of violence at schools and most acts of school violence appear to happen randomly, often out of instant retaliation.”

For the study, Dr Jacobs did surveys at schools across three provinces in South Africa.

“Although it varies in levels of seriousness, incidences of physical violence and verbal cruelty consistently occur at South Africans schools. I found that learners are furthermore regularly mocked, insulted, cursed and humiliated by peers.”
