Implementation of individualized scaffolding construction systems with a large number of construction companies would be challenging.  Its an another disadvantage is that unless properly trained, a construction company trainer may not properly implement scaffolding instruction and therefore not see the full effect.  Scaffolding systems which also requires that the technique give up some of the control and allow the to make errors.This technique may be difficult for contractor,s to do.  Finally the contractor manuals and curriculum guides that they have been exposed to do not include examples of scaffolds or outlines of scaffolding methods that would be appropriate for the specific lesson content.

Thanks for the information .
