What is a scaffolding

Scaffolding is a temporary structure used to support people and material in the construction or repair of buildings and other large structures. It is usually a modular system of metal pipes or tubes, although it can be made out of other materials.
Scaffolding comes from the works of Wood, Bruner and Ross (1976). The term ‘scaffolding’ was developed as a symbol to describe the type of assistance offered by a teacher or peer to support learning. In the process of scaffolding, the teacher helps the student master a task or concept that the student is initially unable to grasp independently. The teacher offers assistance with only those skills that are beyond the student’s capability. Of great importance is allowing the student to complete as much of the task as possible, unassisted? The teacher only attempts to help the student with tasks that are just beyond his current capability.
Scaffolding is a momentary platform constructed for reaching heights above arms' reach for the purpose of building construction, maintenance, or repair. Scaffoldingis generally made of lumber and steel and can range from simple to composite in design, depending on its use and purpose. Millions of construction workers, painters, and building maintenance crews work on scaffolding every day, and due to the nature of its use, scaffolding must be properly constructed and used to make sure the safety of those who use it.
Commercial structure accounts for the largest use of scaffolding, but even residential construction and home improvement projects can sometimes require scaffolding. Professional painters are equipped to quickly and properly construct scaffolding on the job, as are other professionals such as bricklayers and carpenters. Unfortunately, many homeowners attempt to construct scaffolding for personal use without the proper knowledge, which often results in injury. To avoid personal injury when attempting to repair, paint, or preserve your home, be sure you know how to properly and safely erect a scaffolding platform that will provide a stable work surface and will bear the weight you place on it. If you are unsure how to construct or use scaffolding, consult a professional contractor.
Scaffolding can also include breaking a large task into smaller parts, verbalizing cognitive processes, working in peer groups, or prompting. As the student begins to work independently, the teacher removes all or some of the scaffolding.

The benefits of scaffolding include more motivated learners, more time spent on learning with less on searching, and a greater chance of learners acquiring the desired skill.
