The opening chapter states the problem, purpose of study and also provides background to the problem as well as preliminary literature of the study. The other chapter that has substantially enriched the project is chapter two, which provided all the literature, related to the research. The third chapter explains the methodology used in this research study. Data was collected through the use of questionnaires from learners in Gaborone Junior Secondary Schools. All in all, a sample of sixty (60) (n=60) subjects were used to collect data. Chapter four is about data presentation, analysis and interpretation and lastly the recommendations, which are provided to help the authorities as well as the school administrators. The study sought to find out the causes and effects of peer harassment in Gaborone Junior Secondary Schools, as well as the prevalent forms of bullying and the effort undertaken by school administrators and other stakeholders to support victims of peer harassment in the educational system. The researchers' hypotheses were that home background, peer pressure, and popularity are some of the major causes of school bullying, physical and verbal abuse are the prevalent forms of bullying in secondary school, there is . a significant positive relationship between school bullying and learners' low academic achievement and that school administrators and teachers are not supportive to learners who are victims of peer harassment. The findings revealed that indeed, children who come from violent homes, homes faced with divorce, alcoholism, lack of maternal affection and poverty, become bullies. The other ,causes of bullying behaviour according to the study, is negative peer pressure as well as the desire to be popular. The study also revealed that learners who are victims of bullying academically perform poorly, fear going to school, riding a school bus and develop low self-esteem and are depressed. Furthermore, the study found that the school administration and teachers do not make an effort to attend to victims of peer harassment. The study recommends that the Ministry of Education through the work of curriculum developers should provide , policies and programs that address unacceptable behaviour. These polices can include expansion of the school curriculum to cater for guidance and counselling. During the study, the researcher's schedule was affected especially during administration of questionnaires as . a lot of schools were engaged in the Performance Management System exercise (P.M.S), thus some were reluctant to help. / (M.Ed.)
