DA is a method derived from Vygotsky’s (1978)
sociocultural theory. He observed that immigrants were
erroneously identified as having limited intelligence based
on standardized static measures. According to his theory,
high-level mental processes, such as problem solving, voluntary
attention and memory, and concept formation, occur
and develop through interaction with the environment in
daily activities and socialization. Language serves as a tool
that mediates the relationship between cognition and the
environment. According to Vygotsky’s sociocultural theory,
learning moves gradually from being regulated primarily
by the environment to self-regulation (internalization).
