The Profile Map shows a respondent's proficiency estimates on each dimension in a single table. The user selects the Item Set from which the estimates are computed.

  1. To see the Profile map for a student, first select the student, then select Reports - Individual Reports - Profile Map from the menu.
  2. You will be presented with a dialog window of display options as described in the table below. The settings used to generate the report in the example were:
    • Title = Profile Map
    • Item Set = 29-38
    • Display Scores = No
    • Labels = Yes
    • Suggestions = Yes
    • Show in Gray Scale = No
    • Show Full Variable Name = Yes
    • Display All Levels = Yes
    • Suggestions Row Header = To improve your performance, you can (Note that this text does not appear when Display Scores is set to No, because the leftmost column will not appear on the report).
    Table 1. Profile Map Display Options.
    Option Description
    Title The title you provide will appear at the top of the output window.
    Item Set Browse... to the Item Set that you want included. If you want to see all of the items, select the “base” Item Set.
    Display Scores Select Yes to display a column of response scores associated with each category level.
    Labels Select Yes to display Criterion Zone labels at the student’s proficiency level. Select No to display a star at the student’s proficiency level. See "Setting Criterion Zones" for more information about defining the labels.
    Suggestions Select Yes to display suggestions for improvement below the Profile map. Select No to exclude suggestions. See "Setting Criterion Zones" for more information about defining the suggestions.
    Show in Gray Scale Select Yes to display the chart in black and white, No to display in color.
    Show Full Variable Name Select Yes to display the full variable name in the column headings. Select No to display the short variable name.
    Display All Levels This refers to the values that are printed on each row. When set to Yes, all rows display the criterion zone label for each score level. When set to No, only the row associated with the respondent's proficieny level displays the label. The label associated with the respondent's location is displayed in red.
    Suggestions Row Header This entry controls the text that is displayed in the first column of the Suggestions row. Users may keep the default of "To improve your performance you can".


    Figure 1. Profile Map for Anne Jackson after completing Item Set "29-38."

    The Profile Map shows a respondent’s position on each variable for which he or she had a response (represented as a Criterion Zone label or series of red asterisks). Each row in the table represents possible score categories for a variable. The top row is the highest score category. The categories are defined through user-specified Criterion Zones, or cut-point ranges along a logit scale. The ranges are determined separately for each variable and then aligned together for this chart. This means that one variable may define score category 1 with a logit range of –1.0 to -0.25, while another may have score category 1 defined by 0.5 to 1.35. Thus, proficiencies on different variables cannot be compared directly from the data in this chart (a future version of ConstructMap will include a transformation so that the zones can be compared directly). When variables have differing numbers of categories, unused categories (at the top of a variable column) are shaded.

    The Profile Map shown in Figure 1 indicates that after completing the "28-39" Item Set, Anne Jackson was primarily providing completely correct responses to questions that drew upon knowledge of Designing and Conducting Investigations, and was primarily providing responses that were correct but incomplete to questions that drew upon knowledge of using evidence and making tradeoffs in decision-making. The text in the yellow areas are provided as guidance to the student about how to improve performance. These values were entered into the system when ConstructMap was configured for the SEPUP curriculum. See the Setting Criterion Zone Options section for more information.

    Numeric values of the proficiency estimates are not displayed on this map (if you wish to see the estimated proficiency values for each variable for a particular respondent, use the Item Tracking Map, the Diagnostic Map, or the Graphical Diagnostic Map). At the bottom of each column (variable) are optional suggestions for performance improvement. These suggestions, along with the category cut-points and labels, can be modified. See the Setting Criterion Zonesection for more information.

  3. Resize and change the shape of the map by dragging the corners of the map window, or the window edges. You may wish to do this to make the labels or suggestions easier to read.
  4. Print the map by selecting File – Print from the menu. This will print the window in the form you see on the screen.
  5. There is currently no save mechanism for this map.
  6. Close the display by selecting File - Close from the menu, or by clicking on the close box, CloseX.jpg, in the upper right-hand corner.
