Background: The concept of resilience is defined differently in the literature, with the definition depending on the criteria under consideration. Currently, the most commonly used definition is: resilience as "psychological resistance to biological, psychological, and psychosocial developmental risks". In order to systematically enhance resilience, it is necessary to first determine specific training needs. This study examines the resilience status of dental students in Germany from different academic years and derives interventions for resilience enhancement, as the field of dentistry is considered one of the "most stressful professions".

Methods: To determine the resilience status, a questionnaire was developed, consisting of the 10-Item Connor-Davidson Resilience Scale (10-Item CD-RISC), the Maslach Burnout Inventory Scale (MBI), the Negative Self-Image Scale (NSBS), and five self-formulated closed-ended questions. A total of 320 questionnaires were distributed, with 184 responses (43.7% female) received, including partially completed forms.

Results: The resilience status shows an average moderate level of resilience (M=28.43; SD=5.57). The subcomponents of emotional exhaustion (M=23.66; SD=8.32) and reduced personal performance (M=33.69; SD=8.47) indicate an increased risk of burnout, but not depersonalization (M=5.04; SD=5.50). Overall, the participants have a positive self-image (M=1.72; SD=0.69).

Conclusion: The study reveals that dental students have a moderate level of resilience. Dental students are not inherently prone to burnout, but they show reduced levels of emotional exhaustion and personal performance, suggesting a need for interventions in these areas. Possible interventions tailored to these training needs are discussed in the article. Further research is needed to determine the effectiveness of these interventions.

Objectives: Medical education has been revolutionized by the growing importance of digital learning. Little is known about students' online study behaviour and its relationship with exam performance. This quantitative study analyses and describes students' digital learning behaviours in a blended learning curriculum for General practice at Saarland University, Germany. It also examines the relationship between digital learning behaviour and exam performance.

Methods: Cohort and individualized AMBOSS^® user data from 195 students at Saarland University was analysed quantitatively. Performance in course-specific multiple-choice question sessions and user data of the integrated online learning activities were correlated with each other and with General practice exam grades. Anonymized data from 10,534 students from 35 other German universities served as the reference cohort. Differences in digital learning behaviour between the groups were calculated using Mann-Whitney-U-Test for non-normally distributed data.

Results: Students in the blended learning course used integrated content more frequently than the reference cohort (U=48777, p<0.001). The number of digital learning cards read correlated moderately with digital formative assessment performance (ρ=0.331, p=0.005 and ρ=0.217, p=0.034). Formative assessment scores and exam results correlated strongly in the summer semester cohort (ρ=0.505, p<0.001), and moderately in the winter semester cohort (ρ=0.381, p<0.001).

Conclusion: There is a difference in the usage of online learning activities when they are purposefully integrated into a curriculum. Digital learning activities including formative assessment may serve as valuable, constructively aligned exam preparation. This is relevant for medical educators when planning future blended learning curricula and portfolio systems, as it may save financial and human resources.

Objective: Previous research on problem-based learning (PBL) describes that videotaped observations develop meaningful insights into cognitive processes in tutorial groups. Analysis regarding the amount of prior knowledge on learning achievement has not been investigated in medical education so far, although both are key factors of PBL success. Thus, we intended to analyse videos of digital problem-based learning (dPBL) sessions, focusing on knowledge acquisition and interaction dynamics among groups with different levels of prior knowledge to reveal any distinctions.

Methods: This study employed a pilot design by dividing 60 dental students into twelve subgroups with less or more prior knowledge, determined by a pre-semester multiple choice test (MCQ). The groups engaged in videotaped dPBL cases, which were examined regarding group interactions and tutor effectiveness. The learning achievement was assessed through a post-semester MCQ, an oral and practical exam.

Results: The video analysis showed that dPBL groups with less prior knowledge achieved significantly higher tutor effectiveness and group interaction utterances, but that the percentage of time in which utterances occurred was similar in both groups. Related to the MCQ results, the students with less prior knowledge learned four times more than those with profound previous abilities, but no significant difference was found in the results of the oral exam and practical exam.

Conclusions: The interaction dynamics in dPBL depend on the group's amount of prior knowledge. Especially groups including participants with less prior knowledge seemed to benefit from dPBL in comparison to groups with more prior knowledge. The dPBL groups acquired knowledge in different ways during the courses but, finally, all students arrived at a similar level of knowledge.

Objectives: Concept maps are a learning tool that fosters clinical reasoning skills in healthcare education. They can be developed by students in combination with virtual patients to create a visual representation of the clinical reasoning process while solving a case. However, in order to optimize feedback, there is a need to better understand the role of connections between concepts in student-generated maps. Therefore, in this study we investigated whether the quality of these connections is indicative of diagnostic accuracy.

Methods: We analyzed 40 concept maps created by fifth-year medical students in the context of four virtual patients with commonly encountered diagnoses. Half of the maps were created by students who made a correct diagnosis on the first attempt; the other half were created by students who made an error in their first diagnosis. The connections in the maps were rated by two reviewers using a relational scoring system. Analysis of covariance was employed to examine the difference in mean connection scores among groups while controlling for the number of connections.

Results: There were no differences between the groups in the number of concepts or connections in the maps; however, maps made by students who made a correct first diagnosis had higher scores for the quality of connections than those created by students who made an incorrect first diagnosis (12.13 vs 9.09; p=0.03). We also observed students' general reluctance to use connections in their concept maps.

Conclusion: Our results suggest that the quality, not the quantity, of connections in concept maps is indicative of their diagnostic accuracy.

Objective: A simulation game is a valuable method for conveying teaching content in a practical way. The aim was to design a teaching module for medical sociology on the subject of "The German health care system" which would convey the contents and connections to the students in a practical way using a simulation game.

Project description: In addition to the development of scenarios for the simulation game, role cards for various institutions of the health care system were also produced as a result. The students were given the opportunity beforehand to work on theoretical content regarding the German health care system online (the "flipped classroom method"). In the 90-minute face-to-face event the simulation game was played, followed by a feedback session. The initial impressions of the students were collected.

Results: In the 2022 summer semester, a total of 185 students from the 4^th pre-clinical semester took part in the seminar. The students were divided into twelve seminars. One scenario was worked on per seminar. The simulation game contributed to a better understanding of the health care system. The students were generally very satisfied with this type of knowledge transfer and thought that this method might well be integrated into teaching in the future.

Conclusion: Communicating the health care system through a simulation game is evidently suitable for explaining clearly complex issues and presenting the various interests of the individual institutions. In addition, a simulation game stimulates critical debate and can contribute to imparting theoretical content in teaching medical sociology in a practical way.

Objectives: Visual expertise is essential for image-based tasks that rely on visual cues, such as in radiology or histology. Studies suggest that eye movements are related to visual expertise and can be measured by near-infrared eye-tracking. With the popularity of device-embedded webcam eye-tracking technology, cost-effective use in educational contexts has recently become amenable. This study investigated the feasibility of such methodology in a curricular online-only histology course during the 2021 summer term.

Methods: At two timepoints (t1 and t2), third-semester medical students were asked to diagnose a series of histological slides while their eye movements were recorded. Students' eye metrics, performance and behavioral measures were analyzed using variance analyses and multiple regression models.

Results: First, webcam-eye tracking provided eye movement data with satisfactory quality (mean accuracy=115.7 px±31.1). Second, the eye movement metrics reflected the students' proficiency in finding relevant image sections (fixation count on relevant areas=6.96±1.56 vs. irrelevant areas=4.50±1.25). Third, students' eye movement metrics successfully predicted their performance (R²_adj=0.39, p<0.001).

Conclusion: This study supports the use of webcam-eye-tracking expanding the range of educational tools available in the (digital) classroom. As the students' interest in using the webcam eye-tracking was high, possible areas of implementation will be discussed.

Objective: Simulation training provides an important opportunity to accelerate surgical skills acquisition whilst safeguarding patients. This study compares the suitability of different synthetic skin substitutes for use in surgical simulation training.

Design: Data was collected for eight commercially available synthetic skin substitutes and included cost, delivery time, subjective assessment of fidelity by surgeons and trainees, and objective comparison with the biomechanics of human skin was made through cutometry and durometry measurements. Cutometry and durometry data was collected from three healthy adults from the forearm, forehead and back, with measurements being repeated in triplicate. Subjective assessment of skin pad quality was collected using an 8-criteria questionnaire, graded using a 5-point Likert scale for fidelity to normal skin.

Results: The questionnaire assessment was completed by 30 trainees and practitioners. Overall, felt pads received the poorest outcomes in all criteria; cutometry and durometry results demonstrate poor similarity to skin, and felt received the lowest scores in the questionnaire, although the cheapest. Foam dressings were similar in both cutometric and durometric properties to skin of the face, back and arm. Clinical outcomes of foam dressings were similar to the most expensive commercial skin pad.

Conclusions: Bilaminar foam-based dressings provide a low cost, high fidelity non-biological simulation of skin for surgical training, which is non-inferior to more expensive specifically designed products. Many products designed to act as skin substitutes for surgical simulation fail to adequately replicate the anatomical and mechanical properties of skin.
