Although
the prolific Russian psychologist, Lev
Vygotsky, first proposed his sociocultural theory of learning
almost 60 years ago, it has since been rediscovered and applied
to modern instructional environments, especially those utilizing
technology.
Unlike behaviorists, Vygotsky was less interested in manipulating
the environment, and more focused on the social interactions
between individuals of different cognitive ability levels. Vygotsky
believed that human learning was an inseparable function of this
cultural context.
One of his more famous techniques for teaching problem-solving
(which Bruner later termed scaffolding)
required a teacher or other higher ability individual to provide
limited and sequential assistance, and then gradually encourage
students to work independently. Vygotsky identified the Zone
of Proximal Development as the nexus between the inability
to solve problems alone and the successful performance under the
guidance of an expert.
Cognitive apprenticeship is a
recent instructional strategy derived from Vygotsky's sociocultural
theory. The technique utilizes an overview and statement of instructional
expectations, followed by a model
demonstration of the tasks to be learned, and then independent
practice. As the tasks become increasingly
demanding, students eventually reach a point beyond which they
cannot succeed without coaching from the instructor. After guiding
students through successful completion of the tasks, the instructor
gradually reduces the coaching,
allowing the students to perform on their own.
