Activity Averaging Map

The Activity Averaging Map plots one point for each second-tier Item Set, usually comprising a single instrument, test or an in-class assignment. Each point is actually an average of performance on that Item Set and on the two preceding Item Sets (see the discussion on Item Sets for details about how items are selected for each point plotted on the map). Again, a separate map is produced for each dimension, with each being accessible from the associated tab in the upper lefthand corner of the maps. You will also see the alternating horizontal bands for each criterion zone on this map.

  1. To see the Activity Averaging map for a respondent, first select the case, then select Reports - Individual Reports - Activity Averaging Map from the menu. This map option will not be displayed if the project does not have at least two tiers of Item Sets.
  2. The same display options described for the Performance Map will be presented. Select appropriate options and click on OK to continue. A map will be displayed depicting all second tier Item Sets the respondent has attempted.

    Figure 1. Activity Averaging Maps for the DCI and ET variables for Anne Jackson.

    We find that progress for Anne Jackson is not as consistent on the ET variable as on the DCI variable. In particular, we note that performance decreases at ACT 38 on the ET variable while it increases on the DCI variable. We can explore that phenomena further when we look at the Item Tracking Map in the next section.

    Note that the two variables do not necessarily display the same Item Sets along the x-axis. This is because Item Sets that contain no responses that provide evidence of a particular variable are omitted from that variable's mapping. In Figure 1, items from "ACT18" and "ACT25" only provide evidence of the DCI variable, items from "ACT5" and "ACT58" only provide evidence of the ET variable, and items from "ACT12," "ACT38" and "ACT44" provide evidence of both variables.

  4. Resize or change the shape of the map by dragging the corners of the map window, or the window edges. Some actions will crop the window, but dragging back will restore the window contents.
  5. To print the map, select File – Print Selected Chart. This will print the map for the currently displayed variable. Use the tabs at the top of the map to select another variable, and then select File – Print Selected Chart again to print that map. This will print a full-size map. To control the size of the printed map, you may prefer to save it as a JPG or PNG file and then import it into a Word document (see the next step). You can then modify the size directly.
  6. To save the map, select File – Save as JPG or Save as PNG. This will automatically save a graphical file for each variable. For example, entering a filename of "perfmap" generates the files perfmap_DCI.png and perfmap_ET.png.
  7. Close the map window with the Close button at the bottom of the window.
