Abstract
In the introductory physics courses of their studies, medical students face major challenges in terms of physical content. At the same time, students only receive limited feedback on their learning progress and hardly any profession-related content. In the AI4MED project, an AI-based, individualized ePortfolio is being developed to support students of veterinary, dental and human medicine during physics lectures and practicals by providing weekly short tests and subsequent AI-based feedback. This also promotes clinical reasoning and critical thinking. The ePortfolio then supports students in the physical laboratory practicals in combination with a virtual reality (VR) environment tailored to the target group. Taking into account the students' abilities and learning processes, individualized VR visualizations are offered to promote concept understanding, CT and CR.

Abstract
In medical diagnosing, like other knowledge rich domains, collaborative skills are crucial. The Collaborative Diagnostic Reasoning (CDR) model highlights the importance of high-quality collaborative diagnostic activities (CDAs; e.g., evidence elicitation and sharing), influenced by content and collaboration knowledge as well as more general social skills, to achieve accurate, justified and efficient diagnostic outcomes (Radkowitsch et al., 2022). Yet, the CDR model has not been empirically tested, so the relations between individual characteristics, CDAs and diagnostic outcomes remain largely unexplored. This study aimed to evaluate the CDR model by analyzing data from three studies involving 504 intermediate medical students diagnosing simulated cases collaboratively using a structural equation model with indirect effects. Our results revealed various stable relations between individual characteristics and CDAs, as well as between CDAs and diagnostic outcomes, highlighting the multidimensional nature of CDR. While both content knowledge and collaboration knowledge were critical for the quality of CDAs, no individual characteristic was directly related to diagnostic outcomes. The study suggests that CDAs play an important role for successful collaborative diagnosing, especially in simulation-based environments. Content and collaboration knowledge strongly influence CDAs, highlighting the importance of understanding the knowledge of collaborative partners. The CDR model should be revised to emphasize collaboration knowledge over social skills. Training programs should prioritize the development of CDAs to enhance CDR skills.

Abstract
In light of the advancements in medical information, medical education is challenged with equipping students with the skills necessary to effectively navigate this information landscape and make sound judgments (Berndt et al., 2021). Developing critical online reasoning (COR) skills as part of medical studies has become essential – such skills are critical when students use the Internet to retrieve information about patient cases and solve professional problems (Wiblom et al., 2017). A lack of domain-specific (DOM-)COR skills may lead to misconceptions or misapplication of knowledge, ultimately compromising patient safety (Mamede et al., 2019). Thus, our project aims to develop valid assessments to (1) adequately describe DOM-COR in medical students, (2) predict DOM-COR development during academic studies, and (3) predict learning outcomes. Scenario-based tasks are utilized to measure three DOM-COR cognitive skill facets (Molerov et al., 2020): searching for online information (OIA facet); critical evaluation of the information (CIE facet); evidence-based reasoning and synthesizing of the information (REAS facet). A longitudinal study over the first three years of medical studies will examine effects of the medical curriculum on the development of DOM-COR skills based on a random sample of medical students and a comparison group of physics students. We evaluate the medical curriculum by analyzing Internet-based tasks and Internet-like simulations. Our goal is to identify the impact of courses and research activities on student performance. We also consider other key influencing factors such as individual learning prerequisites and interactions with specific properties of DOM-COR tasks or online materials used.
