As a critical course offering, clinical laboratory immunology instills medical students with strong professionalism and practical knowledge, which is increasingly important due to the rapid expansion of clinical immunology technologies, many of which play pivotal roles in the diagnosis and management of abnormal immune function [1]. At universities in China, clinical laboratory immunology is designed to bridge basic and clinical medical knowledge. Students are thus expected to gain a thorough understanding of the technological principles and application of clinical laboratory immunology, which is essential for making clinical diagnoses on issues such as autoimmune disease, cancer, and infectious disease [2]. However, there is currently no specific method for evaluating the various approaches to teaching clinical laboratory immunology in the medical laboratory setting. Especially given the increasing popularity of new teaching strategies, it is therefore important to explore evaluation procedures, with the aim of both enhancing interest among students and ensuring that they are provided with quality medical education.
Given the rapid development of modern clinical immunology theories and applied technologies such as Trained immunity, Immunophotonics, Flow Cytometry and Immunofluorescence techniques, it is often difficult to implement traditional teaching strategies in medical education, as many do not allow for effective student–teacher interactions, especially with limited teaching hours [3, 4]. Under these conditions, students passively accept knowledge through the lecture-based learning (LBL) method, which has shown to be ineffective and unresponsive [5].
Flipped classroom (FC) and team-based learning (TBL) teaching strategies mainly derived from student-centered learning theories, based on the theories of Piaget and Vygotsky [6]. As one of the active learning approaches, the flipped classroom requires students to play an active role in class and construct information by themselves [7]. Students gain knowledge points before class, thus enabling teachers and students to “flip” roles during class [8, 9]. In this context, students are better able to discuss course subjects both inside and outside the classroom, including with their peers. The classroom roles are flipped so that students become the leading role of learning, while teachers become designers and guides of the learning process [10, 11]. Moreover, teachers can replace the lecture-based approach with a variety of new teaching strategies that increase students’ enthusiasm for learning using active learning strategies including FC while deepening their comprehension of basic knowledges [12]. For example, TBL is another student-centered, teacher-directed cooperative learning method based on Vygotsky’s theory, in which students are affected by own or other team members’ actions in class [13]. More specifically, students are divided into small teams (e.g., five to seven students) prior to class. Typically, they are expected to complete a reading assignment before collaborating as a team to resolve a challenging problem that is assigned by the teacher [14]. During class, students will then hold inter-team discussions while the teacher facilitates, assists, and comments on their proceedings [15]. Hence, TBL teaching strategy has been proven to improve students’ attitude, success and motivational levels [6]. Cooperation with FC and TBL will increase the effectiveness of the teaching–learning process compared to using FC or TBL teaching strategy individually, and shows a positive impact on students’ success, attitudes and behaviors [7, 16, 17].
Although FC and TBL teaching strategies have been used by medical education courses (such as Biochemistry, Physiology, Nursing education, etc.) increasingly, only few studies have focused on these strategies in laboratory medicine courses including clinical laboratory immunology [1, 18,19,20]. Given the unique advantages of FC and TBL, we believe they can provide enhanced benefits when combined; in clinical laboratory immunology, this approach should help students master relevant principles and applications for use in their future clinical work. As such, this study developed and implemented a FC with TBL (FC-TBL) program for use among students of a clinical laboratory immunology course.
Under the limitations imposed by the coronavirus disease 2019 (COVID-19) pandemic, many students have accepted at-home medical education, which impels teachers to apply online teaching strategies [21]. With the goal of reforming practices to cultivate undergraduate talents and master the difficult knowledges, we relied on our teaching experience to adjust to these major changes by redesigning the teaching strategies used in some chapters of our implemented coursework. As a response to COVID-19 restrictions, we conducted the FC-TBL course online via Tencent Meeting and the Rain Classroom APPs, then made subjective and objective comparisons of the FC-TBL and LBL approaches based on in-class quizzes, examinations, and questionnaires. We thus found that the online FC-TBL (vs LBL) course was more effective for promoting learning interest, team-based problem-solving, and knowledge mastery, which also provide an example and reference for other medicine and life science courses.
