School bullying occurs every day but students seldom act as defenders. Social and individual processes can easily disengage moral standards. To prevent bullying, knowledge of these processes is necessary. This is my research focus. 

Biography

Robert Thornberg is a Professor of ÌÇÐÄÍøÒ³°æ at the Department of Behavioural Sciences, Linköping University. He earned his Ph.D. in ÌÇÐÄÍøÒ³°æal Research 2006. His current research is on school bullying, especially with a focus on social and moral processes involved in bullying, bystander rationales, reactions and actions, and students' perspectives and explanations.

His second line of research is on values education including morals, norms, and student participation in everyday school life. A third line of research is on teacher education, especially student teachers' motives to become a teacher and their experiences of distressed situations during teacher training. Thornberg uses a range of research methods including qualitative interviews and focus groups, questionnaires and psychometric scales, ethnographic fieldwork, cross-sectional and longitudinal designs, grounded theory, and statistical methods."
