Developmental psychologist Barabara
Rogofff (1990) first explained the term Cognitive Apprenticeship. This model is
supported by Albert Bandura's (1997) theory of modeling, which posits that in
order for modeling to be successful, the learner must be attentive, must have
access to and retain the information presented, must be motivated to learn, and
must be able to accurately reproduce the desired skill. In cognitive
apprenticeships, the activity being taught is modeled in real-world situations.
Definition:- An expert stretches and supports a
novice’s understanding of and use of culture’s skill
All apprenticeship mainly focus on 2
aspects
1)
Activity
in Learning
2)
Situational
learning
Example:- Traditional
apprenticeships, in which the apprentice learns a trade such as tailoring or woodworking by
working under a master teacher
Similarly cognitive apprenticeships
allow the master to model behaviors in a real-world context with cognitive
modeling
Features of Cognitive
apprenticeship:
·
Teachers
acts as Model for students
·
Teachers
(or skilled peers) support students effort as doing the task
·
Encourage
students to continue their work independently
A study conducted in America (Heath
1989) stressed the importance of cognitive apprenticeship. Rich or Middle class
parents engage their children in cognitive apprenticeship by reading picture
books etc with their children before Kinder Garten but poor parents not do so. This
strategy enhances learning ability of the former children to a great extent.
Key Aspects of Cognitive
Apprenticeship:
Experts evaluate when the learner is
ready to take a new step. This timing help
both the expert and the learner.
·
For
the Expert it helps to stop the making direction to students
·
For
learner it helps to guess when expert stop thinking and when the learner has to
take the responsibility to continue the
task
Experts give the students appropriate
opportunities to respond.
·
At
moments when students passed up opportunities to respond the expert noticed
what the student were doing.
·
When
student passed 2 or 3 opportunities expert would continue with further
explanations.
·
If
no evidence of understanding appeared deny that further explanations, experts repeated
or reformulated what they were saying
·
Expert
uses collaborative completion of statements as a way to find out what the
student understood.
·
A
common strategy employed by the expert was to use a hint question to get the student
unstuck
·
Thus,
experts often attempts to evaluate students level of understanding by observing
the looks on their faces and how they
respond to questions
·
This strategy is important in class room
·
Student learning benefited by this
·
scaffolding
and guided participation is used to help the student learn
·
There
are six teaching methods rooted in cognitive apprenticeship theory
·
The
first three (modeling, coaching, scaffolding) are at the core of cognitive
apprenticeship and help with cognitive and metacognitive development. The next
two (articulation and reflection) are designed to help novices with awareness
of problem-solving strategies and execution similar to that of an expert. The
final step (exploration) intends to guide the novice towards independence and
the ability to solve and identify problems within the domain on their own.
·
Modelling is when an expert, usually a teacher, within the
cognitive domain or subject area demonstrates a task explicitly so that
novices, usually a student, can experience and build a conceptual model of the
task at hand. For example, a math teacher might write out explicit steps and
work through a problem aloud, demonstrating her heuristics and procedural
knowledge.
·
Coaching involves observing novice task performance and
offering feedback and hints to sculpt the novice's performance to that of an
expert's. The expert oversees the novice's tasks and may structure the task
accordingly to assist in the novice's development.
·
Instructional
scaffolding is the act of putting
into place strategies and methods to support the student's learning. These
supports can be teaching manipulatives, activities, and group work. The teacher
may have to execute parts of the task that the student is not yet able to do.
This requires the teacher to have the skill to analyze and assess student
abilities in the moment.
·
Articulation includes "any method of getting students to
articulate their knowledge, reasoning, or problem-solving process in a
domain" Three types of articulation are inquiry teaching, thinking aloud, and critical student role.
Through inquiry teaching teachers
ask students a series of questions that allows them to refine and restate their
learned knowledge and to form explicit conceptual models. Thinking aloud requires students to articulate their thoughts while
solving problems. Students assuming a critical role monitor others in cooperative
activities and draw conclusions based on the problem-solving activities. Articulation is described as consisting
of two aspects: separating component
knowledge and skills to learn
them more effectively and, more common verbalizing or demonstrating knowledge
and thinking processes in order to expose and clarify them.
·
Reflection allows students to compare their own
problem-solving processes with those of an expert, another student, and
ultimately, an internal cognitive model of expertise A technique for reflection
could be to examine the past performances of both expert and novice and to
highlight similarities and differences. The goal of reflection is for students
to look back and analyze their performances with a desire for understanding and
improvement towards the behavior of an expert.
·
Exploration involves giving students room to problem solve on
their own and teaching student’s exploration strategies. The former requires
the teacher to slowly withdraw the use of supports and scaffolds not only in
problem solving methods, but problem setting methods as well. The latter
requires the teacher to show students how to explore, research, and develop
hypotheses. Exploration allows the student to frame interesting problems within
the domain for themselves and then take the initiative to solve these problems.
