The Education Endowment Fund describes scaffolding as "‘a metaphor for temporary support that is removed when it is no longer required," in order to enable learners to complete a task that they cannot yet achieve on their own.
Scaffolding can take different forms in class, including:
Visual Aids, such as a task planner
Correcting a misconception or error when doing desk visits
Written scaffolds, such as a writing frame
Time to Talk
Modelling
The tool to the left from the Education Endowment Fund is a means for teachers to reflect on what scaffolding looks like in their classroom.
This short video shows Tom Sherrington illustrating how we can scaffold verbal responses in class.
