If we want each group of students to get a different version of the test, then we may need to create several versions of each numerical questions. I have never done that, but we can try it. An easier way of randomization that we currently follow is just set up the test to appear in a different order for each student.
We have created an online exam instruction emphasizing students for making sure they all use the firefox browser and have access to high speed internet during the test to reduce the technical issues. We can also share that with all.
Another way of randomization is to create a pool of questions like 50-60 questions and set the BB to select only 25 or 30 questions from the pool each time. This way, each student will see a different version of the test.
1. Does one create the questions in Word, say, and then upload them to BB.
No, we have to insert each question into the BB manually unless we use the Cengage test bank questions. We can modify the questions if we decide to use the Cengage test bank. Cengage provides a zip file of the textbook test bank that can be imported easily to the BB. We can modify the questions on the BB if we decide to use the Cengage test bank.
2. How do you handle graphics such as graphs and tables? Do they need to be created in a special format?
We need to save all the figures and tables as a picture and then insert it as an image into BB.
3. When you randomize one version of the test, and the questions are renumbered, how do you control the reference to a Table or Figure?
If say question 1 pertains to Figure 1 in test A, but that is question 10 in version B, does it still refer to Figure 1?
For example, If we have three questions refers to the same graph/table/scenario, we have to repeat the common parts for each question. In other words, tables/figures can not be renumbered automatically.
It would be also better if we don’t write a question that can be solved based on the answer to another question.
4. Do you allow a fixed amount of time on the test?
Yes. We make the test available for two hours but students have only 90 minutes to complete it. If they start the test late, their exam will be submitted at the due time automatically.
5. Do you have any evidence of cheating? If so, how did you detect it?
It is really hard to detect cheating. One recommendation to reduce the possibility of cheating is not to give too much time to students for completing the test. Having a limited time makes harder for them to chat or share their ideas during the test.
