This dataset belongs to a large-scale educational intervention project introducing cultural literacy learning in schools. The dataset includes transcribed dialogic interactions from 111 lessons conducted in classrooms of five countries: England, Portugal, Germany, Spain, and Cyprus. The lessons were part of the same Cultural Literacy Learning Programme made available to teachers from three age groups (pre-primary, primary, secondary) to implement with their ordinary classes during ten sessions. The data are from the third and eighth sessions and followed the same structure, content, and objectives. As the main goal of the project to which the dataset belongs was on cultural literacy learning, understood as dialogic dispositions and values, the data were coded according to a Dialogic Empathy coding scheme presented in detail in Macagno et al. (2020). This rich multicultural, and multilinguistic, dataset is offered for further analysis by different types of researchers, such as linguists interested in intercultural pragmatics or educational psychologists interested in cross-sectional studies of dialogue and reasoning skills.
