This document discusses the importance of understanding learners' social backgrounds and diversity. It explains that social context refers to the specific social settings and unique meanings people assign within a group. Understanding learner diversity means recognizing each individual's uniqueness in emotional, social, and motivational readiness to learn. Vygotsky's social learning theory holds that learning is a social process where we assist each other, and teachers can help students learn within their zone of readiness by providing social assistance. The social nature of knowledge acquisition is that individuals construct meanings through social interaction and activity in social settings. Therefore, for teachers it is important to understand learners' social needs to prepare them for learning and achieve outcomes.
