Ev ve Okul Yaşantılarında Zorbalığa Etki Eden Faktörler: Bir Karma Yöntem Araştırması

Öz

Bu araştırmada, niceliksel ve niteliksel yaklaşımlarla ortaokul öğrencilerinin ev ve okul yaşantılarında zorbalığa etki eden faktörlerin çok yönlü ve kapsamlı bir şekilde belirlenmesi amaçlanmıştır. Araştırma karma yöntem desenlerinden açımlayıcı sıralı desen aracılığıyla gerçekleştirilmiştir. Bu araştırmada çalışma grubu, karma yöntem araştırması tasarımlarında uygulanan sıralı karma yöntem örneklemine (nicel-nitel) göre belirlenmiştir. Bu kapsamda Bursa merkezde bulunan ve basit tesadüfi örnekleme yöntemine göre seçilen on dokuz ortaokulun seçkisiz yöntemle belirlenen şubelerinde öğrenim gören 5. sınıf öğrencileri nicel verilerin toplanması için çalışma grubunu oluşturmaktadır. Nitel veriler anket sorularına verilen yanıtlardan zorbalığa uğradığı veya zorbalık yaptığı belirlenen öğrencilerden elde edilmiştir. Araştırma sonuçları, erkek öğrencilerin kızlara göre anlamlı düzeyde yüksek oranda zorbalık yaptığı ve zorbalığa uğradığını; öğrencilerin okul dışı etkinliklere katılım sıklığı ile zorbalıkta herhangi bir şekilde yer almama arasında pozitif bir ilişki olduğunu; öğrencilerin günlük bilgisayar veya video oyunlarını oynama süresi ile zorbalıkta yer alma durumları arasında negatif bir ilişki olduğunu; zorbalıkta herhangi bir şekilde yer alma ile arkadaşlık ilişkileri arasında negatif bir ilişki olduğunu; öğrencilerin zorbalıkta yer alma durumları ile kendilerine yönelik değerlendirmelerine ait puan ortalamaları arasında yüksek düzeyde negatif bir ilişki olduğunu; öğrencilerin sıklıkla fiziksel ve sözel zorbalığa uğradığını; zorbalık yapan öğrencilerin kendileriyle alay edildiği ve küfredildiği için zorbalık yaptığı; hem zorbalığa uğrayan hem de zorbalık yapan öğrencilerin zorbalığa uğradığında çoğunlukla ortamdan uzaklaştıkları ve zorbalığın çoğunlukla öğretmenlerin bulunmadığı yer ve zamanlarda yapıldığını göstermektedir.

Factors Affecting Bullying in Home and School Life: A Mixed Method Research

Öz

In this research, it was aimed to determine the factors affecting the bullying in secondary school students’ home and school life in a multifaceted and comprehensive manner with qualitative and quantitative approaches. The study group of this research was determined according to sequential mixed method (quantitative-qualitative) sampling, one of the mixed method research designs. In this context, for collection of the quantitative data, fifth-grade students studying in randomly-selected classes at 19 secondary schools located in the centre of Bursa and chosen by the probability sampling method made up the study group. The qualitative data were obtained from the answers given to the survey questions by students determined to have been subjected to bullying or to have engaged in bullying. The research findings reveal that male students engaged in bullying or were subjected to bullying at a significantly higher rate than female students. There was a positive relation between the engagement of the students' in out of school activities and not participating in any kind of bullying situations. It was found that there was a negative relationship between playing daily video or computer games and participation in bullying situations. It was also found a negative relationship between friendship relations and being in bullying anyhow. There was a strong negative relation between the avarage points of self evaluation of students and participating in bullying situations. Students were frequently exposed to physical and verbal bullying; that students who engaged in bullying did so because they were themselves made fun of and sworn at; that when bullying took place, both students who were subjected to bullying and those who engaged in bullying generally moved away from the scene and that bullying was generally carried out in places where and at times when teachers were absent.
