High-quality teaching in basic medical courses is the cornerstone of undergraduate clinical medicine education (Tie et al., 2024), It directly affects students' grasp of theoretical knowledge and profoundly impacts their future clinical practice and research capabilities (Krishnappa et al., 2023). As higher medical education reform progresses, educators and teaching researchers increasingly recognize the need to focus on cultivating students' practical skills, innovative thinking, and humanistic qualities(Guo, 2010; Li & Zhou, 2018; Qiao et al., 2023). Traditional lecture-based teaching methods are no longer fit for purpose in modern medical education. Consequently, many research teams have proactively sought to enhance talent cultivation by innovating in course design, teaching methods, and the integration of basic and clinical courses (Kim, 2020; Si, 2020; Yu, 2024; Zhang & Ma, 2023). Although these attempts have achieved some success, they still struggle to meet the demand for medical professionals with comprehensive innovative spirits and strong adaptability. Against this background, our research team delved into the application and effects of DT in interdisciplinary teaching of basic medical courses, aiming to provide valuable insights for innovation and development in clinical medical education.
To achieve this goal, we focus on the DT concept. Initially prominent in the business sector, DT is a unique, human-centered, systematic approach known for its disruptive problem-solving capabilities (van Velzen et al., 2024; Wolcott et al., 2021). In recent years, DT has been widely and deeply applied in guiding educational innovation, especially in project-based teaching, and has achieved considerable theoretical development (McLaughlin et al., 2022; Skywark et al., 2021). Applying DT in teaching means that teachers, as "designers," must start from the real needs of student "users," (Badwan et al., 2018), define specific problems, design courses and solutions (Smith & Nigro, 2023), and continuously optimize through iteration and feedback to achieve the best possible outcomes (Schaller et al., 2023). Our analysis of the training needs of clinical medicine undergraduates at applied universities had led us to conclude that DT can and should be integrated into all learning stages of basic and clinical medical courses as an educational philosophy. It can also provide specific, innovative steps and tools throughout these courses(Guo et al., 2024; McLaughlin et al., 2022; van Velzen et al., 2024), aligning perfectly with the current outcome-oriented mainstream teaching philosophy (Kondo et al., 2022; Li et al., 2023).
It is crucial for undergraduate education in clinical medicine to explore histology and embryology in depth (Guo et al., 2024; Hortsch, 2023; Tauber et al., 2021). Together with systematic anatomy, this course builds an important foundation of medical knowledge and hold a significant place in all undergraduate medical education (Cheng et al., 2021), It lays a solid foundation for subsequent studies in physiology, pathology, and clinical practice in internal medicine, obstetrics, and pediatrics (Hortsch et al., 2023; Lu et al., 2023). However, limited course hours and large class sizes (usually up to 200 students/classroom) constrain the teaching approach, necessitating a predominantly lecture-based method despite the student-centered teaching philosophy. This status quo has led to “habitual discomfort” such as students' lack of interest in learning, low classroom engagement and low learning satisfaction (Eng-Tat et al., 2023), which in turn affects the degree of achievement of the established teaching objectives and students' sense of achievement (Dennis & Creamer, 2023). Therefore, this course urgently needs reform and innovation, making it an important platform for our study.
The Jining Medical University DT Teaching Innovation Team and the Histology and Embryology Teaching Research Team jointly planned the Creative Histology and Embryology Learning Skills Expansion Competition (Creative H&E). This was an interdisciplinary extracurricular project for first-year undergraduates in clinical medicine, psychiatry, medical imaging and other medical specialties. This competition has been held for three consecutive years, with this year's theme being " Creative H&E Textbook play."(https://jcxy.jnmc.edu.cn/2024/0527/c233a157918/page.htm). The project consists of three stages: preliminary round—creative script writing; semifinal—creative scenario video shooting; final—live "Creative Histology" stage play (script murder) presentation. Each stage's content aligns precisely with the course's teaching schedule, as shown in Fig. 1. In the first stage, students learned basic DT knowledge in groups and practiced these steps through two assignments (filling out an empathy map and creating a pain point solution). From the preliminary round onwards, students were fully engaged in the project, confidently using DT methods to complete the script writing, video shooting, and live presentation stages. Students followed the DT steps meticulously, rigorously testing and iteratively optimizing each work (Liu, 2023; van Velzen et al., 2024). Throughout this process, feedback from instructors and other students provided valuable insights, helping students identify issues and propose specific improvements, significantly enhancing learning outcomes and project performance. (Badwan et al., 2018; Holt et al., 2022; Schaller et al., 2023). The final competition of this year's "Creative H&E " showcased 10 winning entries, including "The Mystery of the Epithelium," through serialized videos in news media.
To scientifically assess the actual impact of the interdisciplinary " Creative H&E " project, we employed qualitative research methods to delve into students' learning experiences. From the perspective of award-winning students, we meticulously analyzed their feedback to comprehensively understand the practical application of this innovative teaching method. Through such research, our aim was continuous refinement of teaching methods to ensure their effectiveness and feasibility in practical education. We firmly believe that this study not only strengthens the improvement of DT in teaching methods but also offers valuable insights and references for research into other innovative teaching approaches, thereby advancing continuous innovation and development in medical education.
