PKMAP= customize Table 36 diagnostic maps |
PKMAP= can be used to customize Table 36 diagnostic maps. These maps are based on the KIDMAP - www.rasch.org/rmt/rmt82k.htm

A list of color names is shown at https://www.w3schools.com/colors/colors_names.asp - Hex values can also be used. These color names and hex values are used for 1C-5C.
Bold: \<b\>...\</b\> but bold for 1M and 1R may cause misalignment. Use a color instead.
Italic: \<i\>...\</i\> but bold for 1M and 1R may cause misalignment. Use a color instead.

Each row is .17 logits
Responses are positioned vertically to match the expected scores in Table 2.2
Responses in the top category, here "2", always go in the left-hand column.
Responses in the bottom category, here "0", always go in the right-hand column.
Responses in intermediate categories, here "1", go in the left-hand column if they are above the person ability.
Responses in intermediate categories, here "1", go in the right-hand column if they are below the person ability.
Left column: success = higher rating on the rating scale
Item 18 (bottom left of PKMAP) is the easiest item. Person 6 rated in the top category 2. - a success - an "easy level reached"
"18.2" on the PKMAP is positioned at the ability level corresponding to that rating on that item.
"18.0" would have been much lower in the right-hand column.
Item 20 (upper left of PKMAP) is a hard item. Person 6 rated in the middle category 1. - a partial success - a "hard level reached"
"20.1" on the PKMAP is positioned at the ability level corresponding to that rating on that item.
"20.2" would have been much higher in the left-hand column.
"20..0" would have been much lower in the right-hand column.
Example 3: To display webpage maps by classroom:
ASCII=Webpage
@CLASS = class-identifying columns
TFILE=*
PSELECT=@CLASS=1
OFILE=CLASS1.HTM
36
PSELECT=@CLASS=2
OFILE=CLASS2.HTM
36
etc.
*
Example 4. Automating Example 3 for many classrooms. Here is a simple procedure:
1. Output the PFILE= to Excel
2. Delete all columns except the person label
3. On the person label column:
Excel: Data, Text-to-columns, Fixed format, and mark the classroom codes, OK
so now the classroom codes are in a column by themselves, say column U
4. Select the classroom codes
5. Insert pivot table
6. Location of pivot table column V
Add to report: check box
Pivot table output to column V
7. Copy the unique classroom codes from column V to columns B and D
8. Arrange the columns:
blank column ( column A)
classroom codes (column B)
blank column (column C)
classroom codes again (column D)
blank column (column E)
9. Fill column A with
%PSELECT=@CLASS=
10. Fill column C with
%OFILE=CLASS-
11. Fill column E with
.HTM%36
So now row 1 looks like:
%PSELECT=@CLASS= 1 %OFILE=CLASS- 1 .HTM%36
12. Combine cols A-E into column F. Fill column F with
=CONCATENATE(A1, B1, C1, D1, E1)
Column E looks like:
%PSELECT=@CLASS=1%OFILE=CLASS-1.HTM%36
13. Copy column E into Microsoft Word
14. In Microsoft Word, replace % with a new-line code ^p
The column in Word now looks like
PSELECT=@CLASS=1
OFILE=CLASS-1.HTM
36
15. Save this to a separate text file, mytfile.txt
16. In your Winsteps control file, put
TFILE=mytfile.txt
