GPSCOR

gp.hqnIf appropriate, the Lowest Question No. Used may be coded to request that data be picked up from the answer sheets beginning at a point other than question number one. On earlier versions of the Request for Service form, these 3 columns have the heading Batch Number rather than Lowest Question No. Used. Regardless of the column heading, the number coded in this field is used to specify the first question of interest on the answer sheet.

The Highest Question No. Used refers to the last question number (row) used for responses on the answer sheet. This number will be larger than the number of questions on the test if some intermediate question numbers have not been used. It will also be larger in those situations where responses to some questions other than the test questions are asked following the test per se.

The Question Length is the maximum number of choices (response positions) used for any of the questions. Note that, for the 10-choice answer sheet, the responses are numbered 0 through 9 but the Question Length is actually 1 through 10.

The No. of Keys refers to the number of key sheets that are to be used in scoring the answer sheets. If scoring by the GPSCOR program is not required or not applicable, then the number of keys will be 0.

A key sheet is a General Purpose Answer sheet that has the correct answers marked on it. If an answer is not marked on the key sheet for a given item, that item will not be scored for that particular key. You may use up to 8 key sheets with GPSCOR. A separate score will be computed for each key sheet. If you are using more than one key sheet, please number the keys so that we know the order in which they should be processed. If you wish to have a count of the number of incorrect responses, include a key sheet that has the correct answers marked on it and which also has the M bubble under Sex filled in. M in this case is used to represent Minus. The score produced in this case will be a negative score. If an examinee does not respond to a particular question, this is not counted as an incorrect response.

N.B.: Since the University of Alberta General Purpose Answer Sheet does not have a grid for 'Sex', accommodation for this option is provided by marking the X bubble on the line which illustrates 'Incorrect Marks'.

If the number of items marked on a key sheet is less than the "Highest Question No. Used", please write a note in the Notes section of the Request for Service Form to confirm that this difference is intentional (so that we don't have to phone you to confirm it).

 


The Main Parameters are used to communicate the following information to the GPSCOR scanner program (please write the number in the box provided and fill in the corresponding bubble to request each of the desired actions):

A. Name, (sex, grade and birthdate) processing:

0 = do not include in output file
1 = transfer to data file
2 = reject sheet when the NAME has blank columns between the first column and the last character in the field
3 = reject sheet when the NAME is totally blank

B. Identification number:

0 = do not include in output file
1 = transfer to data file

C. Special codes field (including SA1 and SA2 on the UofA GPA sheet):

0 = do not include in output file
1 = transfer to data file
2 = reject sheet if marks in the special code field are quite light

 

D. Item responses:

0 = do not include in output file
1 = transfer numeric values of responses to data file
2 = transfer alphabetic values of responses to data file
3 = transfer true-false (T, F, ?) values of responses to data file

E. Composite scores:

0 = do not compute composite scores
1 - 6 = compute this many composite scores

F. Formula scoring:

0 = do not apply formula scoring option
1 = use formula scoring option; a maximum of 4 keys may be used if you choose this option

 

The Secondary Parameters are used to communicate the following information to the GPSCOR scanner program (please write the number in the box provided and fill in the corresponding bubble to request each of the desired actions):

K. Check for left-justified Identification Number:

0 - 9 = demand this number of digits in the Identification Number counting from the left

L. Check for right-justified Identification Number:

0 - 9 = demand this number of digits in the Identification Number counting back from the last column in the grid

M. Check for multiple responses to the questions:

0 = reject the sheet if there are multiple responses to a question
1 = output a blank when a multiple response is encountered
2 = output an asterisk (*) when a multiple response is encountered

N. Check responses to questions for light marks:

0 = don't worry about the presence of light marks
1 = reject sheets having some questions omitted and light marks for more than 10% of the responses (this is to guard against the possibility that the questions which appear to have been omitted were actually just marked too lightly)
2 = reject sheets having ANY light marks (this is important on tests which penalize students for incorrect responses--often called "correction for guessing"--which includes use of the formula scoring option in F above)

One of these two options must be chosen. If you request "Pocket Questionable Sheets for MANUAL Verification", sheets that are rejected because they appear to be improperly completed (for reasons such as those requested in the Secondary Parameters above) will be diverted to a special hopper where the operator can review the sheet to see if it can be repaired. After any possible repairs are made, the rejected sheet is scanned again and forced to be accepted even if repairs cannot be successfully performed.

If you request "FLAG Questionable Fields and Process as if Normal", sheets that appear to be improperly completed will not be selected for operator attention. Instead, a '?' will be placed at the beginning of the field that contains questionable results. Choosing this option means that the sheets will be processed without operator assistance, e.g., a sheet which has been completed using pen instead of pencil will be accepted as though it was completely blank.


Please indicate the type of data processing you require, if any, from this menu. Normally, you will only select one of these choices. "Other" might be some pre-arranged processing using, for example, SPSS. Sample output may be viewed at Itemanal, Examtab, and Queseval.

This part of the menu allows you to request generation of a variety of 'class lists' which contain the Name, Identification Number, Special Codes and Scores for each answer sheet. Only the fields that you have requested to have included in the output file (using the Main Parameters options) will appear in these lists, e.g., if you specify '0' under option 'A' of the Main Parameters, the Name field will not be included in the output file and therefore will not be available to include in the class lists. You may ask for lists sorted according to a variety of fields. If you ask for a list sorted by Identification Number, you may also ask that the Name field be dropped from that list. This yields a listing that is suitable for public posting.

The numbers following the 'Sorted by Score' option refer to the sequential number of the key that generated that score (if Composite scores were not requested) or to the sequential number of the Composite score if such were requested.

When these lists are generated, you may ask that the scores be scaled so that they are 'out of' a total other than the total possible raw score, e.g., you may ask that the scores be converted to percentages or scaled so that the maximum possible score is, say, double the number of questions on the test.

In addition to the printed output described above, you may request that the output be placed in any combination of 3 types of files:

  1. the sorted data may be placed in a plain text file. This is a copy of the file that we send to the printer to generate your printed output when you mark the option Hard Copy. This file will normally have the suffix .srt. If this file is sent to you, it may be opened with a text editor such as WordPad on a PC or TextEdit on a Mac.
  2. marking eClass requests a file suitable for uploading to eClass which contains each student's last name, id number, user ID, and score. In order to create this file, you will need to provide us with the Registrar's catalog number (Class ID) for the class. This file will normally have the suffix _w.csv
  3. marking Excel requests that the sorted data be placed in a comma-delimited (*.csv) file which may be used to input the data into programs such as Excel. The file generated by this request will contain the combination of name, id number, special codes and scores that have been transferred from the answer sheets. It will be sorted according to the first sort request that is specified, e.g., if you ask for a sort by both name and id the file will contain data sorted by name. This file will normally have the suffix.csv

For the last 2 options above, you may also request one or both of two additional options by marking the corresponding bubble(s):

    • Wrongs: add a column that contains a list of items that the student got wrong and/or
    • Scored Responses: add a column that contains the student's responses using uppercase letters to indicate correct responses and lowercase letters to indicate incorrect responses.

Contents of these columns are illustrated in the eClass sample output file.
