e-exams in a university bio-chemistry
laboratory: technology problems and
its impact on student experience
2. Focus of this paper – key research question
What was the impact on student perception
measures when technology problems occur
during an exam event?
Prior work has not addressed this specific
question!

The study was carried out within the broad context of the development of a university-wide digital assessment
strategy at UNSW.
This study focused on the ‘computer lab’ context – desktop computers supplied by the university.
Students used Safe Exam Browser + Moodle Quiz + Lab Archives (lab e-note book).
This paper reports on one pilot (Note: two other pilots followed later in the year).
4. Method
Case study: BioChem Lab exams, July 2019
Participants: 215 second year undergraduate students across 4 class groups.
Equipment: Windows lab PCs with Safe exam browser + Moodle Quiz + LabArchives (e-notes).
Data collection: Survey using Likert item responses.
Exam room procedure:
1. Students enter the room and were seated at a suitable bench.
2. Students can read a printed instruction sheet with steps to get started.
3. Once logged into the desktop computer, students then logged into the LMS using Chrome browser and then clicked on a link
leading to a SEB setting file. This then launched Safe Exam Browser. Students were required to again login to the LMS and
were then taken to the Moodle quiz start page.
4. When all students were ready to begin, the invigilator announced the start of the exam by providing the Moodle quiz
password. This enabled all students to start at the same time. Quiz auto-save occurred each 30 seconds.
5. Exam end: students used the Moodle quiz submission button and then exited SEB. The quiz was set to automatically submit
if the quiz timer expired.
6. Students were requested to log-off from the computer.
7. Students completed the post-exam survey before leaving the room.

Other labs + 500 seats (later)
Total 1900 seats.
Safe Exam Browser (SEB) was used to secure the computer
6. Results – impact of technology problems on
student perceptions
The ratings given by students at the practice and two exam events.
The final exam (Post 2) experienced technical problems. This is reflected in the lower ratings.
Ease of use, reliability and security were significantly impacted (Sign Test: Post 1 v Post 2)
Chart shows the trend in ratings between events.

Post 2 event AM v PM sessions: difference ratings
The PM session of the Post 2 exam event experienced greater technical disruption. This is
reflected in the lower ratings given by the PM participants.
The chart shows the DIFFERENCE between the ratings given by AM and PM participants.
