Scaffolding
A scaffold is:
Scaffolding:
• A temporary platform, either supported
from below or suspended from above, on
which workers sit or stand when
performing tasks at heights above the
ground.
Scaffolding:
the context provided by knowledgeable
people such as adults to help children to
develop their cognitive skills.
An important aspect of scaffolding is that
there is a gradual withdrawal of support as
the child’s knowledge and confidence
increase.
Without Scaffolding in a traditional
classroom
• Typical teaching: teacher tells and the student
listens, then the student tells (or regurgitates
information on a written test) and the teacher
evaluates.
• The knowledge is declarative, decontextualised,
and inert (think of a classroom dominated by
lecture). Knowledge is not personally
constructed nor applied.
Without scaffolding:
With Scaffolding:
Teachers model strategies and knowledgemaking in the context of task completion,
and then students attempt to do the task
the way the teacher did it.
• The learning here is directed by a teacher who
models appropriate strategies for meeting
particular purposes, guides students in their use
of the strategies, and provides a meaningful and
relevant context for using the strategies.
• Support, in the form of explicit teaching, occurs
over time until students master the new
strategies, and know how and when to use
them.

What does scaffolding do?
• Provides clear direction and reduces students’
confusion
• Clarifies purpose
• Keeps students on task –
• Clarifies expectations and incorporates
assessment and feedback
• Points students to worthy sources
• Reduces uncertainty, surprise, and
disappointment
• Delivers efficiency
• Creates momentum
How do we teachers
scaffold?
• Motivate or enlist the child’s interest related to
the task
• Simplify the task to make it more manageable
and achievable for a child
• Provide some direction in order to help the
child focus on achieving the goal
• Clearly indicate differences between the
child’s work and the standard or desired solution
• Reduce frustration and risk
• Model and clearly define the expectations of
the activity to be performed
Other ways we scaffold:
• Offering Explanations
• Inviting Student Participation
• Verifying and Clarifying Student
Understanding
• Modeling Desired Behaviours
• Inviting Students to Contribute Clues
• Working with peers who may be helpful

The Levels of Scaffolding
Level 0: Provides no assistance,
Level 1: Offers a general verbal
encouragement,
Level 2: Gives specific verbal instruction,
Level 3: Assists in choosing materials,
Level 4: Prepares materials for use,
Level 5: Demonstrates use or operation

Welcome to:
Queen’s “Save Your Life” Teaching Program
Have you ever taught swimming?
• Who? Your students are not swimmers.
They are 4-6 years of age, and have never
swum. Many are afraid of the water. Few
have been in water without their parents.
However, some are comfortable in water
and even may enter water independently.
Many cannot float. Some are hysterical.
All are cold.
• What? Your course: To achieve the
Tadpole badge in life-saving and
swimming, the children must be able to
swim to the opposite width of the pool
independently.
• (To achieve the Minnow badge, children
must swim across the pool, in the deep
end, independently. But that’s another
course!)
• Where? Your classroom: the pool,
equipped with these resources: floaties,
tables, water toys, flutter boards, anything
that money can buy to teach kids to swim
• Why? (end or goal) Overarching or
General Expectation:
• By the end of this course, and to achieve
the Tadpole badge, the child will swim
across the pool independently and
comfortably.
