A group of people sitting together listening to one person talk are not socializing. Once one person stops monopolizing their collective attention, then they can socialize. The more effective alternatives to lecture bring learners into more engaged contact with each other.

Very narrow concept of socializing. Being in a classroom together is already a signal of group inclusion. Having a collective experience to relate with each other later is part of socialization.
