Ensure that intermediate landings are used wherever a ladder exceeds 9 metres in height. If students are evidently less prepared for this learning approach and begin to compare themselves to their peers, their self-efficacy and motivation to learn can be hindered. The Zone of Proximal Development: A Spatiotemporal Model. Barriers other than guard rails and toe boards can be used, so long as they are at least 950 mm high, secure and provide an equivalent standard of protection against falls and materials rolling or being kicked from any edges.

Therefore, it is impossible to provide exact answers under the conditions you propose because of the multitude of other variables that may exist. Install ties as the scaffold is erected and only remove them in stages as it is struck.If a tie is removed to allow work to proceed, an equivalent tie must be provided nearby to maintain stability. In addition, scaffolding is often used to bridge learning gapsi.e., the difference between what students have learned and what they are expected to know and be able to do at a certain point in their education.
