Full edition for scientific use. This study explores the relationship between pre-service teachers' language-related biographical experiences and their noticing of linguistically diverse classroom situations. The sample consists secondary education pre-service teachers from the University of Vienna. Data collection involved a three-part questionnaire and retrospective interviews using stimulated recall. The first part of the questionnaire elicited participants' language-related biographical experiences, encouraging reflection on their personal experiences with linguistic diversity. In the second part, participants analyzed two video clips depicting linguistically diverse classroom situations and evaluated how language use affected student learning. The final part of the questionnaire gathered demographic data, including participants' home languages, study subjects, and experience with multilingual education. Additionally, retrospective interviews with a subset of participants were conducted using stimulated recall to examine how their language-related biographical experiences shaped their perceptions of the classroom situations. During the interviews, participants reflected on their thought processes while completing the questionnaire. By investigating these connections, this study provides insights into how pre-service teachers' personal language-related biographical experiences affect their noticing of linguistically diverse contexts, offering valuable implications for improving teacher education programs designed to enhance teaching in multilingual classrooms. This is the data set from the questionnaire.
