Abstract

The purpose of this survey was to explore dental students’ perceptions of the ubiquitous-based test (UBT) system that was applied to a trial dental licensure examination at a dental school. The fourth-year students of a dental school took a UBT and a paper-based test (PBT) which were administered in the format of the Korean Dental Licensure Examination. The UBT was conducted with a tablet computer with the face tracking function for preventing cheating. A survey was conducted online after the two exams ended. The questionnaire examined possession of a tablet computer, skillfulness of smart devices, the students’ perceptions about the convenience and satisfaction, reliability, and preference of UBT. The items related to the students’ perceptions were scored using a 5-point Likert scale. There were no statistically significant differences in overall perceptions of UBT by gender and possession of a tablet computer. In the convenience and satisfaction category, the convenience of viewing images received the highest mean score of 3.54 ± 1.17. The response to the reliability of exam results was positive (3.78 ± 1.31), whereas the reliability of the cheating preventing function received the lowest mean score (1.89 ± 1.12). The preference of UBT compared to PBT received a mean score of 2.36 ± 1.32. The disadvantages of UBT mentioned by the students included neck and eye fatigue, and difficulty concentrating on the exam. Some issues identified in this study can be helpful to improve the UBT system, and it will be a useful assessment tool that allows for various multimedia materials in dental education.
