  • Teachers and students perceptions towards online clerkship for international bachelor of medicine and bachelor of surgery students during coronavirus disease 2019 epidemic

    Objective To investigate the problems and needs of teachers and international bachelor of medicine and bachelor of surgery (MBBS) students in the online clerkship since the outbreak of coronavirus disease 2019. Methods In May 2020, questionnaires, telephone communication and face-to-face interviews were conducted among 85 international MBBS students and clinical teachers of 10 related departments in West China Hospital, Sichuan University. Teachers and students perceptions towards online clerkship were collected from five aspects including department orientation, attendance, teaching plan, assignment & assessment, and overall evaluation. Results Four departments and 43 students (50.6%) thought that online clerkship increased time input, while 3 departments thought that students’ enthusiasm decreased significantly compared to ordinary clerkship. Six departments reported that students’ compliance was poor; 58 students (68.2%) reported that they could not experience the real clinical environment. All departments reported difficulties in completing procedures and skills, and believed the teaching objectives were only partially achieved; 78 students (91.8%) thought that the effect of online clerkship met with their expectations; 16 students (18.8%) were very satisfied, and 59 students (69.4%) were satisfied. The majority of students believed that the advantages of online clerkship were that they had more time to prepare for their licensing examination [66 students (77.6%)] and could ask questions online at any time [48 students (56.5%)]. Conclusions There are both pros and cons in the online clerkship. It has put forward higher requirements for the efficiency and accuracy of English communication between teachers and students, and for the self-restraint and discipline of students. Under the current global epidemic situation, we should make full use of the information technology to constantly strengthen the practical education.

  • From Identifying Problems to Developing Evidence-based Solutions in Teaching and Management of Overseas Medical Students: Preliminary Course Evaluation and Its Long-term Initiative

    Objectives To establish a course evaluation model for overseas medical students in West China Medical School of Sichuan University, to identify problems in teaching and to solve problems based on evidence so as to futher improve the quality of teaching. Methods We conducted a preliminary course evaluation to determine the limitations of our evaluation methods and to convey our intention to related stakeholders. Firstly, we identified problems in teaching according to the feedback from our students using a questionnaire. Secondly, we proposed an initial list of possible solutions to these problems based on evidence from literature searching and discussion within the Department of Teaching Affairs. We submitted the initial list to the administrative departments, teaching departments (teachers) and students to identify applicable solutions through two rounds of formal consensus. Their attitudes to this procedure of evaluation and decision-making were collected. Finally, incentives were given out by administrative departments and teaching departments to facilitate the implementation of applicable solutions. Results Teachers’ English ability and the didactic teaching methods were the most concerned problems. In addition, some semesters and courses were not well arranged and there was not enough practice time. An initial list of 14 items was submitted to teaching departments and students. They all agreed with the procedure of evaluation and decision-making. We also found that some aspects of the evaluation methods and styles need to be improved. An additional paper would report further results. Conclusion This preliminary evaluation was helpful for improving teaching and formal evaluation in the future. We need to strengthen the English language skills of younger faculty and gradually adopt a model of student-centered and enquiry-based teaching. This process of evaluation and improvement should be applied as a long-term policy and an evidence-based research group should be established to work together with our quality assurance unit.

  • Exploration and Practice of Problem-Based Learning (PBL) as a Separate Course for 8-year Medical Program

    To cultivated competent clinicians with the potential to be future pillars and leaders is the educational objective of an 8-year medical program at the West China School of Medicine, Sichuan University. Problem-based learning (PBL) is more effective than traditional, passive, didactic teaching in training of communication skills, information management and critical thinking and research. These are included in the Global Minimum Essential Requirements in Medical Education (GMER). We introduce our practice of PBL as a separate course for the 8-year medical program, including its design, preparation, implementation and evaluation. We discuss why it is designed as a separate course and implemented in multiple semesters with fewer cases in each semester. The move from giving a fish to people to teaching people how to fish, and from teacher-centered to student-centered teaching is a radical transformation of educational concepts and the traditional teaching-and-learning model. Such a change cannot happen in a single step and we hope that this model PBL course, focusing on training in methods and skills, will facilitate the concept transformation and the involvement of all our teachers and students. This should help our teaching to evolve continuously, develop a system for evaluating PBL and lead to the gradual incorporation of PBL into our discipline-based courses or organ system-based courses.

  • A preliminary discussion on the integrated mode of talent evaluation for research-oriented hospital: from “all or nothing” to “Gestalt”

    At present, Chinese hospitals widely use a single qualified talent evaluation system. This talent evaluation system has certain limitations. Therefore, based on the long-term demand of research-oriented hospitals for talent team construction, and the limitations of the existing talent evaluation system, this article preliminarily discusses the integrated mode of talent evaluation for research-oriented hospital with integral, qualitative and whole person evaluation based on the Gestalt theory. This model contributes to comprehensively and authentically reflecting the contributions and influences of the evaluated individuals in terms of their professional level, comprehensive abilities, and moral character in research-oriented hospitals. Moreover, it is necessary to fully integrate artificial intelligence and 5G information technology to explore and integrate various evaluation methods into a comprehensive evaluation system for talents in research-oriented hospitals that combines scientific evaluation weights, realizing intelligent, visual, refined, and scientific integrated evaluation.
