The effects of classroom composition and size on bullying and victimization of italian and immigrant high school students
Bullying is one of the most serious problems faced by young people at school. Due to its well-documented negative impact on their well-being and learning, its monitoring and prevention is now a highly relevant issue. The present study uses multilevel modelling to investigate the effects of the class characteristics (the number of students, the proportion of male students and immigrant students, the overall socio-economic level and the initial achievement level) on bullying and/or victimization, also controlling for high school typology.
