Test Scoring and Frequency Scanning Description
The computerized Test Scoring program is used to grade multiple choice examinations. This program compares student answers to answers on an Instructor Control form and produces scoring information. The program processes the following standard optical scanner forms used at the University of Delaware:
What is Frequency Scanning?
Three Frequency Scanning programs are available, identified by three different colored scan forms (bubble sheets). These programs are used to generate frequency counts of responses (commonly used for course evaluations) or to enter data in a file to be used on a central UNIX system account. The standard form choices include the following:
The Test Scoring and Frequency Scanning programs reside on the
central UNIX systems and are operator controlled (not self-service).
They are used in conjunction with data read from standard scan forms
(bubble sheets) by an optical mark reader. To request a Scan job for
either program, submit your completed forms to the Smith I/O Counter
located in room 004 Smith Hall.
This page contains answers to some of the questions more commonly asked about Test Scoring and Frequency Scanning.
Test Scoring jobs must include brown Student Response forms; a properly filled in Blue Instructor control form; and a Test Scoring request card, including your UNIX usernumber or username. A departmental UNIX Scanning Project is also necessary, but most departments already have active scanning projects.
Frequency Scan jobs must include brown, pink, or teal Response forms; a properly filled in Processing Control form (a teal Control form for teal scan jobs, a pink Control form for pink scan jobs, and a blue Control form for brown scan jobs); and a Frequency Scan Request Card including your UNIX usernumber or username. A departmental UNIX Scanning Project is also necessary, but most departments already have active scanning projects.
On the blue Instructor Control form in the area designated FOR INSTRUCTOR USE ONLY, fill in the following with a #2 pencil:
- Control and Key bubble
- First Section bubble
- Last Number Used bubbles (e.g., fill in 50 as 050)
If you are trying to use some of the Standard Options, you should make sure that the Standard Scoring (no options) bubble IS NOT filled in. If it is, all of your "Standard Options" marks will be ignored.
This means that you forgot to fill in the Last Number Used bubbles. To remedy the problem, fill in the Last Number Used bubbles on the Control form (right justify the number; e.g., 50 should be 050) and resubmit the job.
Yes. On the Instructor Control form, fill in choice 1 in column 5 (Standard Option 5). This tells the Test Scoring program to create a file which contains the file identifier, the section numbers, the student names, ID numbers, raw scores, and scores. The file will appear directly in your home directory within 24 hours.
On the Instructor Control form, fill in the Control and Key and First Section bubbles. Fill in Additional Section instead of First Section when appropriate. Also, fill in the Last Number Used bubbles. In the Standard Options section, fill in choice 3 in column 4 (Standard Option 4). Before this will work correctly, each student must fill in choice 1 under the EXTRA OPTIONS column 3 on his/her brown student response form . By filling in that choice, students are giving permission to post their grades. Note that if you plan to post grades with a student's identifying number, the student should not use his or her regular Student ID. Rather, you should provide the students with substitute numbers which provide the students with anonymity. User Services staff can help you to devise these substitute ID numbers.
This simply means that the CONTROL and KEY bubble on the Control form wasn't filled in. To correct the problem, fill in the bubble and resubmit the job.
It could be one of several things:
- You may not have supplied your UNIX usernumber or username on the test scoring request card. Resubmit the job using your UNIX usernumber or username on the request card.
- You may have filled in the Standard Scoring bubble. In this case, the program ignores any Standard Options you may have chosen. Erase the Standard Scoring bubble and resubmit.
- You may be looking in your e-mail rather than in your home directory. Check your home directory for a file called "tscrXXX.data.bin", where XXX is either the three digits "000" or the numbers you entered in Extra Options, columns 1-3, and bin is replaced by the number of your test scoring job.
Yes. You can tell the program that the maximum score is not equal to 100 by marking 1 in the Standard Options 10 bubble. You must also tell the program what the maximum score is by marking it in Extra Options, columns 7-9 (right justify the number, e.g., enter 75 as 075).
You can designate two correct answers by using an Alternate Key sheet. To use an Alternate Key sheet, place another blue control form behind the main blue Instructor Control form and Weight Sheet (if there is one) and fill in the Alternate Key bubble. Fill in one of the correct answers on the main Instructor Control form and the alternate answer on the Alternate Key sheet. Do NOT fill in answers on the Alternate Key sheet for questions that have only one correct answer.
You can make some questions worth more than others by using a Weight Sheet. To use a Weight Sheet, place another blue sheet behind the Control form. If you are using an Alternate Key Sheet, place the Weight Sheet between the Control and Alternate Key Sheets. On the Weight Sheet, fill in the Weight bubble in the section designated For Instructor Use Only and assign a weight between 1 and 5 (a=1, b=2,c=3, d=4, e=5) for each question. Items you leave blank will be given a weight of 0 and NO points will be given for the correct answer to the question.
To give credit to all students, you must leave the answer blank in the scoring key on the Instructor Control form. However, if a student leaves the answer blank on his/her response sheet, he/she will not be given credit for the question. Also, this option can NOT be used in conjunction with Standard Option 6 (request that questions be deleted).
Forms can be purchased from Central Stores.
