Immersive medium for early clinical exposure - knowledge acquisition, spatial orientation and the unexpected role of annotation in 360° VR photos

AIM

360° VR photos could be a low-threshold possibility to increase early clinical exposure. Apart from granting insights into local routines and premises, the medium should facilitate knowledge acquisition and spatial orientation depending on its design. This assumption, however, is not yet substantiated empirically. Thus, three hypotheses were tested in consideration of Mayer's modality principle: 1) Providing 360° VR photos as visual reference improves retention and comprehension of information. 2) The annotation of text boxes in 360° VR photos compromises spatial orientation and presence. 3) Annotated audio commentary is superior to annotated text boxes in terms of cognitive load and knowledge acquisition.

METHODS

Using head-mounted displays, students of human (N=53) and dental medicine (N=8) completed one of three virtual tours through a surgical unit, which were created with 360° VR photos. In the first two variants, information about the facilities, medical devices and clinical procedures was annotated either as text boxes or audio commentary comprising 67 words on average (SD=6.67). In the third variant, the same information was given separately on a printed handout before the virtual tour. Taking user experience and individual learner characteristics into account, differences between conditions were measured regarding retention, comprehension, spatial orientation, cognitive load, and presence.

RESULTS

Concerning retention and comprehension of information, annotated text boxes outperformed annotated audio commentary and the handout condition. Although annotated audio commentary exhibited the lowest knowledge test scores, students preferred listening over reading. Students with an interest in VR and 360° media reported higher levels of enjoyment and presence. Regarding spatial orientation and presence, no significant group differences were found.

CONCLUSIONS

360° VR photos can convey information and a sense of spatial orientation effectively in the same learning scenario. For students, their use is both enjoyable and instructive. Unexpectedly, the ideal mode of annotation is not dictated by Mayer's modality principle. For information like in this study, annotated text boxes are better for knowledge acquisition than the subjectively preferred audio commentary. This finding is probably contingent on the length and the quality of the annotated text. To identify boundary conditions and to validate the findings, more research is required on the design and educational use of 360° VR photos.

Did video kill the XR star? Digital trends in medical education before and after the COVID-19 outbreak from the perspective of students and lecturers from the faculty of medicine at the University of Ulm

Aim: Using a comparison of digital teaching in medicine before and after the COVID-19 outbreak, the aim of the study was to examine how ad hoc digitization has changed (1) the design of digital teaching, (2) the attitudes toward and the capabilities of digital teaching and learning and (3) the future importance of individual digital teaching elements. Methods: Students and lecturers from the Medical Faculty of Ulm were asked to voluntarily participate in online surveys during the summer semesters of 2019 and 2020. The data was subsequently analyzed from a longitudinal and cross-sectional view descriptively as well as by using t-tests and Chi2-tests. In addition, using regression analyses, the results were controlled for associations with age, study progress, and media affinity. Results: In the summer semester 2019, 163 students (6.1% response rate) and 56 lecturers (11.5%) participated in the surveys. In the following year, the participation increased to 285 students (10.4%) and 64 lecturers (12.8%). Video-based teaching elements such as videoconferencing and lecture recordings were increasingly used after the COVID-19 outbreak and considered more significant for future teaching. In contrast, virtual reality, augmented reality and 360°-videos, grouped under the term extended reality (XR), are descriptively becoming less important. Most lecturers would like to teach more digitally even after the pandemic but fear a decrease in learning effectiveness and contact with students, who tend to prefer asynchronous learning opportunities. Conclusion: Video-based teaching elements proved to be a low-threshold and time-efficient solution during the lockdown and were also recommended for future use. The XR technology has been put on the back burner for the time being, but in view of the increased digital teaching motivation and capabilities, it can be assumed that lecturers will recognize and use the potential of XR as soon as they have the freedom to design innovative teaching again.

The Use of a Mobile Learning Tool by Medical Students in Undergraduate Anatomy and its Effects on Assessment Outcomes

Hand-held devices have revolutionized communication and education in the last decade. Consequently, mobile learning (m-learning) has become popular among medical students. Nevertheless, there are relatively few studies assessing students' learning outcomes using m-learning devices. This observational study presents an anatomy m-learning tool (eMed-App), an application developed to accompany an anatomy seminar and support medical students' self-directed learning of the skeletal system. Questionnaire data describe where, how frequently, and why students used the app. Multiple choice examination results were analyzed to evaluate whether usage of the app had an effect on test scores. The eMed-App application was used by 77.5% of the students, mainly accessed by Android smartphones, and at students' homes (62.2%) in order to prepare themselves for seminar sessions (60.8%), or to review learning content (67%). Most commonly, students logged on for less than 15 minutes each time (67.8%). Frequent app users showed better test results on items covering eMed-App learning content. In addition, users also achieved better results on items that were not related to the content of the app and, thus, gained better overall test results and lower failure rates. The top quartile of test performers used the eMed-App more frequently compared to students in lower quartiles. This study demonstrated that many students, especially the high-performing ones, made use of the eMed-App. However, the app itself did not result in better outcomes, suggesting that top students might have been more motivated to use the app than students who were generally weak in anatomy.

Innovative Lehrmethoden: Einsatz eines ophthalmochirurgischen Wetlabs im Studentenunterricht

Hintergrund Ein erhöhter Bedarf an ärztlichem Nachwuchs in Deutschland führt dazu, dass der Wettbewerb um die besten Köpfe schon während des Studiums beginnt. Daher ist es Aufgabe der Universitätskliniken, ihren Studierenden bestmögliche Lehrveranstaltungen anzubieten, um Interesse am jeweiligen Fachgebiet zu wecken. Wir überprüften deshalb den Einfluss eines ophthalmochirurgischen Wetlabs auf die Lehre im Rahmen des klinischen Studienabschnitts.

Material/Methoden Im Rahmen der Intensivwoche Augenheilkunde an unserer Universitätsklinik wurde den Studierenden die freiwillige Teilnahme an dem ophthalmochirurgischen Wetlab angeboten. Zu Beginn und am Ende der Intensivwoche sowie am Ende des Wetlabs beantworteten die Studierenden Fragebögen mit Fragen zum Interesse an dem Fachgebiet Augenheilkunde sowie der konkreten Bewertung des Wetlabs.

Ergebnisse Das Interesse der Studierenden an der Augenheilkunde konnte durch die Intensivwoche und zusätzlich durch das Wetlab gesteigert werden. Das Wetlab bereicherte die Intensivwoche und wurde von den Teilnehmenden mit der Schulnote 1,12 bewertet. Die Gesamtbewertung der Intensivwoche war unter Teilnehmenden des Wetlabs signifikant besser als in der Gruppe ohne Wetlab-Teilnahme. Das Wetlab bereitete den Studierenden große Freude, ermöglichte das Anwenden des theoretisch erworbenen Wissens, erlaubte wertvolle Einblicke in das Fach Augenheilkunde und war problemlos umsetzbar.

Schlussfolgerung Die Integration eines Wetlabs in die Lehre im klinischen Studienabschnitt wird von den Studierenden sehr positiv bewertet und ermöglicht diesen einen wertvollen Einblick in das Fachgebiet Augenheilkunde sowie in das Berufsfeld des Augenarztes.

How do German medical students perceive role models during clinical placements ("Famulatur")? An empirical study

BACKGROUND

Studies have demonstrated the importance of role models in medical education. Medical students in Germany participate in clinical placements ("Famulatur") that last 4 months in total and represent the first real-world setting where students encounter possible role models in their clinical education. These placements are an extracurricular activity, however, and regarded as the "black box" of medical education. This study aimed to evaluate whether and how students experience role models during clinical placements, the qualities associated with potential role models and whether role model-related learning gains are relevant.

METHODS

We recruited 96 students (mean age: 23.83 years; 75% female) in their 5th to 9th semesters at the Faculty of Medicine at the University of Ulm, Germany, who were participating in a clinical placement between July and October 2015. Participants completed a questionnaire at the beginning of a 5-day working week to record sociodemographic and other information and another one at the end of the week to assess various aspects of their experiences. On each of the 5 days, they completed a structured questionnaire to record their perceived role models and self-assessed learning gains.

RESULTS

Role models and role modelling play an important role in clinical placements. The positive function of medical staff as role models predominated (88.4%) across all specialties. Junior doctors were the most frequently perceived role models (28.5%), followed by consultants (25.1%) and nursing staff (22.4%). The most commonly perceived positive quality was the interaction with students (16.5%), followed by team behaviour (13.6%), interaction with patients (13.6%) and professional expertise (13.4%). Students also had various kinds of learning gains such as knowledge or skills.

CONCLUSIONS

Although these clinical placements are extracurricular activities in Germany and their content is not regulated, they are home to a relevant amount of role modelling. Students experience the various medical professions in different roles and in a range of tasks and interactions. Defining basic learning objectives could help to increase the relevance of these placements for the medical curriculum in Germany and transfer the associated learning gains from the hidden to the open curriculum.

[Augmented Reality in Ophthalmology: Technical Innovation Complements Education for Medical Students]

BACKGROUND

At the Medical Faculty of the University of Ulm, the learning objectives of ophthalmology are taught to students in a one-week block course in the fourth year of study. According to the National Competency-based Learning Objective Catalogue Medicine (NKLM), one of these learning objectives is the clinical examination of the eye, including the eye fundus examination. In order to best train this expertise as defined in the NKLM, a novel, augmented reality-based training simulator (Eyesi Indirect, VRmagic Holding AG, Mannheim, Germany) was integrated into the teaching at the University Eye Hospital Ulm. During the block week, two key questions were examined: Does the one week block lesson increase interest in ophthalmology? How do students assess the use of an innovative e-learning technology compared to three other classical teaching methods for learning ophthalmoscopy?

MATERIAL/METHODS

As part of the student teaching (block weeks July and October 2016), 292 students were questioned by questionnaire anonymously and on a voluntary basis regarding their assessment of the block week and the training simulator at the beginning and end of the one week event. The ophthalmoscopies were classically practiced on the ophthalmoscope trainer, head model and on fellow students and then performed on the new training simulator.

RESULTS

Overall, there was little interest among the students in ophthalmology. However, the block week helped to increase interest (p < 0.001). The assessments of attractiveness before and after the block week of ophthalmology as a later professional goal and as an optional subject in the practical year were also significantly increased (p < 0.001 or p = 0.031). With regard to the use of e-learning technologies, it was shown that the handling of the simulator for learning ophthalmoscopy was rated more attractive by the students than the classical technology-based teaching methods (all p < 0.01). The joy of learning could only be further increased by practicing on a fellow student (p = 0.051).

CONCLUSION

The results of the present study show a positive impact of the block week on the attractiveness assessment of the specialty by the participating students. Innovative e-learning methods can increase the enjoyment of learning. However, the training simulator cannot provide a complete replacement of the training on a real person.
