Aim To test the usability and user experience of a newly self-developed eLearning tool to teach PET/CT and CT to undergraduate medical students.
Methods The eLearning tool permits to display PET and CT DICOM images web-based. It contains a healthy subject with anatomical annotations and a clinical case study. The usability and user experience of the eLearning tool was evaluated in undergraduate medical students of the medical faculty of the RWTH Aachen. We applied a survey based on different already existing and validated questionnaires such as System Usability Scale (SUS) and User Experience Questionnaire (UEQ-S) as well as specific questions regarding the eLearning tool.
Results 38 volunteers (9 males) participated in our study. Applying the SUS resulted in a mean of 82.24, and a median of 83.75. This positive evaluation is supported by the results of the UEQ-S that were 2.2 with regard to the pragmatic quality, 2.3 with regard to hedonic quality and 2.3 for overall quality indicating a very positive evaluation. In the free-text answers, students emphasised easy and intuitive use of the eLearning tool that was additionally described as interesting and exciting. The students also positively mentioned the case study and the possibility of practice-based learning. Negative aspects were mainly problems with synchronisation of the PET and CT images.
Conclusion The positive evaluation is encouraging and form a foundation for further development of the eLearning module. It may be the basis for the implementation of a sustainable blended learning concept in the nuclear medicine curriculum.
