Hierarchical Alignment of Timelines part of Cutting Edge:Rates and Time:Teaching Activities
In the hierarchical alignment activity students progressively and hierarchically align scale information to a spatial linear representation. The progressive alignment of scales may alleviate the conceptual dissimilarity between human scales and extreme scales by providing greater structural alignment across changes of scale. The hierarchical organization highlights how each temporal scale is related to the others, helping to populate each scale with boundary information by providing internal structure of magnitude relations within event boundaries.
