Cheating prevention tools and resources
Besides online surveillance, a combination of didactic considerations and tools can be used in order to improve exam quality and minimize fraud risks.
- Anti-cheating strategies per exam type
- General recommendations
- Test - MC/closed questions
- Essay assignment
- Oral exam
Didactic considerations / examination design
Conversion to individual exam forms as much as possible
Randomizing questions per student, so that each student receives a unique exam
Selecting questions from a large item bank or parameterized so that each student has different questions.
Calling in random students after the exam with image and sound
Open questions instead of closed questions
More interim formative examination
Not a summative examination every course unit separately: merging of course unit examination to reduce pressure. This examination could, for example, take the form of a cross-curricular oral exam, paper or assignment that assesses knowledge, understanding and skills
Time limitations (cannot always be technically adapted sufficiently and are sensitive to technical problems on the part of the University of Groningen and the student)
Strict start and end times to restrict access
Making backtracking impossible
Limiting the time per exam question
Raising awareness of scholarly conduct and ethical behavior during lectures
Fraud Detection Tools
Essay plagiarism scanner Ouriginal
Analysis of logs and grades (Nestor logs download)
Analysing the data that was collected and generated about the student who took the exam (user logs and autosaves)
Analysing non-personally identifiable data on previous exams (e.g. results), to assess whether substantial deviations have occurred that indicate possible cheating in the online
Extra measures (conditional)
Exam on campus (on request)
Exam with online surveillance (according to the guidelines)
Anti-cheating strategies per exam type
For different exam types, different strategies can be followed to prevent fraud. Furthermore, a few methods to get an indication of fraud using Nestor tools are mentioned (detection). Apart from prevention and detection, sanctions are the third component of combatting fraud. The Board of Examiners is authorized to pass judgement on students who are suspected to have committed fraud.
Disclaimer: Think carefully before adjusting your exam, as changing the set-up might introduce an extra testing variable. For instance, stricter time restrictions also test how quickly students are able to answer questions, even though this might not be a learning objective. Be sure to check the exam with the Board of Examiners if you do make any changes.
Independent of the type of exam or type of questions, there are a few general guidelines to follow to prevent or detect fraud.
Note: matching IP addresses do not prove physically working together (the students could be housemates), nor do different IP addresses rule this out (one could be on a mobile hotspot).
Test - MC/closed questions
This type of exam has the highest risk of fraud, due to the lack of unique answers.
In (essay) assignments, students answer the same question but their answers are generally long enough to be unique and therefore the risk of fraud is medium.
Because every submission is unique for this type of exam, the risk of fraud is small. The main concern is to make sure the students do the work themselves.
Since the examiner can see the student at all times, the risk of fraud is small.
