Abstract

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.

Zusammenfassung

Ziel Testen der Benutzerfreundlichkeit (Usability) und des Anwendungserlebnisses eines neu entwickelten eLearning-Tools zum Unterrichten von Medizinstudenten in PET/CT und CT.

Methoden Das eLearning-Tool ermöglicht die webbasierte Darstellung von PET- und CT-DICOM-Bildern. Es enthält Bilder eines Normalprobanden mit Annotationen der anatomischen Strukturen und eine klinische Fallstudie. Die Usability und das Anwendungserlebnis des eLearning-Tools wurde an Medizinstudenten der Medizinischen Fakultät der RWTH Aachen evaluiert. Wir haben eine Umfrage durchgeführt, die auf verschiedenen bereits existierenden und validierten Fragebögen wie System-Usability-Scale (SUS) und User-Experience-Questionnaire (UEQ-S) sowie auf spezifischen Fragen zum eLearning-Tool basiert.

Ergebnisse 38 Freiwillige (9 Männer) nahmen an unserer Studie teil. Die Anwendung des SUS ergab einen Mittelwert von 82,24 und einen Median von 83,75. Diese positive Bewertung wird durch die Ergebnisse der UEQ-S gestützt, die hinsichtlich der pragmatischen Qualität 2,2, hinsichtlich der hedonistischen Qualität 2,3 und hinsichtlich der Gesamtqualität 2,3 betrugen, was auf eine sehr positive Bewertung hindeutet. In den Freitextantworten wurde der einfache und intuitive Umgang mit dem zusätzlich als interessant und spannend bezeichneten eLearning-Tool hervorgehoben. Die Studierenden äußerten sich auch positiv über die Fallstudie und die Möglichkeit des praxisbezogenen Lernens. Negative Aspekte waren hauptsächlich Probleme bei der Synchronisation der PET- und CT-Bilder.

Schlussfolgerungen Die positive Bewertung ist ermutigend und bildet eine Grundlage für die Weiterentwicklung des eLearning-Moduls. Es kann die Grundlage für die Umsetzung eines nachhaltigen Blended-Learning-Konzepts im nuklearmedizinischen Lehrplan sein.
