摘要： Background: In medical education various non-digital teaching methods are established. However, studies have proven that the immersive character of virtual reality (VR) applications positively impact the understanding of spatial relationships. This study outlines the development and pilot testing of a novel system for collaborative, case-based VR teaching, utilizing real-time volume rendered computed tomography (CT) data of thoracic cases among graduate students. Methods: A system was configured and deployed to provide real-time volume rendered CT data in a collaborative, multiuser VR environment. A thoracic surgery VR course was implemented into the surgical graduate curriculum, which has subsequently been evaluated with questionnaires. Results: Seventy students assessed the curriculum through a questionnaire. Usability was rated intuitive (77.14 %) while few students (5.71 %) reported cyber sickness. A vast majority (98.57 %) agreed VR improved their understanding of anatomy compared to traditional methods and most students found learning more effective. (88.57 %) and joy during participation was rated high (97,14 %). A majority of the students (61.43 %) believed VR could partly replace traditional methods. They supported integrating VR into preclinical (81.43 %) and clinical teaching (94.29 %) as well as taking VR courses from home (78.57 %). Most participants (90,72 %) encouraged the expansion of VR infrastructure. Conclusion: The concept of a collaborative real-time VR-based educational program in medical graduate teaching has proven its technical feasibility and positive acceptance with a desire for more VR integration in surgical curricula. A two-armed study will be conducted to evaluate the objective impact as the expansion of VR environments for teaching continues.

摘要： Background: Educational spaces, which represent a vital setting for students' learning activities, significantly influence both learning efficiency and physiological health. As university teaching spaces are characterised by high occupancy density and prolonged occupancy, it is vital to address the problem of elevated CO2 concentrations in these spaces. Although effective ventilation design can improve indoor air quality, the relatively short ventilation periods in cold regions of China, driven by winter insulation requirements, often lead to substandard indoor air quality. Purpose: Based on predicted mean vote (PMV), this study explored the effect of natural ventilation on indoor CO2 concentration during the transition season in cold regions and proposed reasonable optimization strategies. Method: Through the method of combination of measurement and simulation, an effective design method of doors and Windows and an intermittent ventilation strategy for improving the indoor environment quality of teaching space in universities in cold regions of China are put forward. Result: The results revealed that indoor CO2 concentrations exceeded the standard limit of 1000 ppm for the majority of the periods studied. Peak indoor CO2 concentrations reached 1970 ppm, 2751 ppm, and 3200 ppm in large-, medium-, and small-sized classrooms, respectively. The duration of exceeding CO2 concentration accounted for the highest proportion of class time, which were 89%, 93%, and 88%, respectively. Furthermore, optimisation of door and window design and ventilation methods was carried out for a representative medium-sized classroom. The simulation results indicated that while maintaining indoor comfort (-0.5 < PMV < 0.5), peak indoor CO2 concentrations during class periods decreased from 2551 ppm to 1149 ppm, and the proportion of time for which CO2 concentrations exceeded standards decreased from 87% to 47%. Conclusions: This study suggests that relevant codes and standards should be refi

摘要： This exploratory case study investigates the boundary-crossing learning patterns of 53 Chinese non-universitybased teacher educators (NUBTEs) as they develop their second-order teaching competency by developing model lessons in a formal professional development (PD) program. The study identifies three patterns in the development process: a) Enhancing disposition by transforming identity from teachers to teacher educators;b) Enriching knowledge by coordinating between different sources;and c) Improving practice by reflecting on the feedback from stakeholders after engaging in teacher education tasks. These patterns jointly explicate NUBTEs' second-order teaching competency development process and indicate theoretical and practical implications for advancing NUBTEs' professional learning.

关键词： Ectopic pregnancy   Problem-based learning   Case-based learning  

摘要： ObjectiveThis study explored the effectiveness of combining problem-based learning (PBL) and case-based learning (CBL) in the clinical teaching of ectopic pregnancy. Methods: Fifth-year students majoring in clinical medicine were recruited from the Department of Gynecology at the Hengyang Central Hospital and Hainan General Hospital between September 2023 and June 2024. The students were randomly assigned to either the combined PBL-CBL or the traditional group. At the end of the class, both groups of students were required to complete a post-class quiz and an anonymous questionnaire. ResultsThe basic knowledge score in the combined PBL-CBL group was significantly higher than that in the traditional group (42.6 +/- 3.6 vs 35.0 +/- 2.3, p = 0.000). Similarly, the case analysis score was higher in the combined PBL-CBL group than that in the traditional group (37.1 +/- 6.2 versus 33.8 +/- 5.7, p = 0.013). The scores for learning motivation, understanding, student-teacher interaction, communication skills, clinical thinking skills, self-learning skills, knowledge absorption, and satisfaction with the course in the combined PBL-CBL group were significantly higher than those in the traditional group (p < 0.05). However, the score for the amount of free time consumed by the combined PBL-CBL group was significantly higher than that of the traditional group (p < 0.05). ConclusionThe study suggests that the combined PBL-CBL teaching method might be a promising new mode of gynecological education.
