Scaffolding in the United States always has been viewed as a strictly functional creation, wholly utilitarian in that it is designed to get workers and material up and down safely and efficiently.
In practice, this means that the scaffold is at a 1.3-degree inclination from the base to the 500-foot mark, conforming to the sloping face of the monument.
The scaffold, which was constructed in New Jersey and brought to Washington in stages on flatbed trucks, was erected by a crew of 26 working in three teams, one crew at the top, another at the middle and the third as ground support.
The best of all of these efforts always made significant use of scaffolding to organize and support the student investigation or inquiry, to keep students from straying too far off the path while seeking "the truth" about whatever issue, problem or question was driving the project.
The scaffolding serves as an introduction, not as a corral.
Scaffolded lessons still require hard work, but the work is so well centered on the inquiry that it seems like a potter and wheel.
