|Abstract:||Graphing is fundamental in the scientific process. Scales are key but little-studied components of graphs. Using a "fine-grained constructivist" perspective, we investigated the resources undergraduate students activate in constructing a scale for difficult data sets ranging over 10 or more orders of magnitude. Following a constant comparison method, we identified resources including: show all elements, zoom in, ratio, halving, and conversion. Students also used their knowledge of bar graphs, histograms, and logarithmic, powers of ten, and linear scales as resources, at times inappropriately. Implications for instruction are outlined.|
