To prevent cheating in online exams, it would be useful to first review how students cheat.
The following are some common ways of cheating in online exams:
- Unreasobale or unlimited Exam duration: Not setting a proper exam duration (start, end, and exam duration settings) can be a problem, even if start and end times are defined in some institutions, as defining an excessively long exam time or an exam that lasts from morning until evening is an invitation and even encouragement to cheat. In addition, the rights of other students who take the same or similar courses are also violated. The solution is to define a realistic and fair exam duration, just like in face-to-face exams, without forgetting the concepts of justice and fairness.
- Communication groups: Instant sharing of the answers of the solved questions by setting up communication groups can only solve cheating on random questions or questions that are diversified with different values.
- Sending exam questions to online sites and receiving the answers of the questions by sending them back. This type of cheating can only be solved by sequential questions and preventing the viewing and returning of the question. Also, a fair and reasonable exam duration setting is necessary.
- Opening a new tab/window or browser next to the internet browser page during the exam and searching for the solutions of the questions on electronic environments on the internet or sending emails to previously agreed persons to solve the question. This possibility can be prevented by setting the exam system's internet browser to kiosk mode through the Secure Browser setting.
- Same questions and answers for everyone. In this case, sharing the questions and answer choices directly through communication groups is possible. The solution is to have random questions and answer choices for each student.
- Unlimited Examination Entrance: One or more students who do not expect anything from the course, drop the course, or know for sure that they will fail, entering the exam first and sharing the questions one by one in groups, creating a copy question and answer pool, and then all other students entering the system and marking only the questions and their relevant correct answers. This possibility of cheating can be reduced by limiting the entry time to the exam.
- Use of open artificial intelligence programs/applications that are available to everyone online or in the form of an application.
After summarizing the most common cheating methods in online exams, the following techniques can be used to minimize these possibilities:
- The priority is to create a well-planned question pool entirely composed of new questions that are different every year and every term.
- In this context, one of the things to do is to create a question pool for each section separately, which is quite diverse, even classified according to difficulty levels, and which produces different results by giving different numerical values to the same difficulty and question set to create an exam pool. Thus, even if similar questions come to students who know each other, communicate, or even sit next to each other, the results will be different because the numerical values of the numbers will be different. Even if they come as similar questions from random questions, at least copying in the first stage will be prevented because the numerical values will be different.
- It is essential to set questions as random and as a single question on each page.
- One of the things to be done is to make sure that the start, end, and duration settings of the exam are made, and the student finishes the exam at the end of the specified time for solving the questions. Once the time settings mentioned are made, the remaining time on the system will be displayed continuously, and the exam will be automatically saved and closed at the end of the time.
- One of the ways to prevent cheating, especially in online exams, is to ensure that the questions appear sequentially, not free, one after the other, and only forward, and to prevent going back to previous questions. That is, it is to prevent students from copying the questions, sharing them with someone else, or finding the correct answers somewhere, and then returning to answer them.
- Another way is to ensure that the questions and answer options are selected randomly during the exam. Thus, the possibility of similar or the same questions coming to close students who know each other, form a group or communicate is reduced, preventing copying.
- Preventing students from opening another application in the background
during the exam is another way to prevent cheating. This method, which
can be used as a way to prevent students from searching for solutions to
questions in another environment by connecting to the internet, is to
take the exam in a Secure/Protected Browser mode. That is, the browser that is
opened will be in kiosk mode and cover the entire screen, allowing the
student to use only the question screen, preventing another browser or
tab from being opened.
- Ensuring that students enter the exam only in the allowed time at the beginning of the eaxmination, in the first 10 or 15-mins., depending on the situation, and preventing them from entering the exam in the following minutes is a way to prevent cheating. Thus, as soon as the exam starts, all students will enter the exam, and their time will begin.
- Another method is to use some special software, sign online course registration requirements and rules for students at the beginning of the term, and install software that does not allow other connections and background applications in their PC/Table/Smartphone during exams. However, there may be cost and hesitation both at the institutional and student level.
- During the exam, monitoring and controlling the student and their surroundings through multiple cameras is another way of supervision. However, this method will require multiple supervisors to control multiple cameras during the exam, leading to institutional and student-level costs and concerns (such as monitoring personal environments).
To prevent the use of open-access artificial intelligence programs online or through applications, questions should be prepared in image format rather than direct text format. Here, questions should be presented as an image with only the question text in text format or even the entire question in image format, with other necessary information provided in a suitable manner for solving the question. This may not be possible for every question, in which case the question should be created using complex watermark patterns or other designs and must be submitted in image format. As current artificial intelligence applications still use version 3.0 or 3.5, they cannot yet accept image or voice inputs. However, in the future, with version 4.0 or 5.0, using different designs in the background (like CAPTCHA) for image-format questions and submitting questions to the system in this way should be considered as a way to minimize cheating.
Finally, it may not be possible to apply all of these methods simultaneously, but combining appropriate ones will be the most intelligent approach.
