Heterogeneity, Diversity, Inclusion: Few terms are currently as central to contemporary educational policy, scientific, and pedagogical discourse. The significant heterogeneity of learning groups necessitates finding a balance between the common and the individual in teaching. This volume explores the question of what perspectives "Young Science" offers for collaborative learning while considering individual learning prerequisites. Theoretical questions are discussed, and the development, implementation, and evaluation of specific practical models are presented to support the establishment of sustainable concepts for dealing with heterogeneity.
