In medical education, the explosive growth of medical knowledge and technology such as artificial intelligence has brought about the need for change in the existing lecture-based teaching structure. Many medical schools are introducing flipped learning for training future health professionals [1].

Flipped learning stems from a constructivist learning theory in which learner-centered education is achieved through collaboration. Many medical schools have introduced flipped learning as a new teaching method to stimulate students’ critical thinking and active participation [2]. Flipped learning is a kind of small group activity method in which students independently explore course content online at pre-class and then in class engage in interactions in the form of problem- solving and discussion [3]. Flipped learning has the pedagogical features of encouraging self-directed learning, inquiry learning, and learner-centered learning, which these may be influenced by the personal orientation each individual learner. This study focused on learners’ unique learning styles.

A learning style refers to an individual’s manner and attitude in acquiring and processing information in learning situations [4]. In a psychological sense, a learning style pertains to the way students concentrate and is a tool for acquiring and processing knowledge, information, and learning experiences. In a cognitive sense, it refers to a tool that shapes perception, processes information, and builds concepts and principles. Learners have different learning styles [5]. Thus, each one uses his/her unique methods to acquire information and comprehend the facts presented.

Over the coronavirus disease 2019 (COVID-19) pandemic, various types of collaborative activities were conducted using synchronous online classes. A typical method is to use Zoom, a video communications application. In the present study, the online flipped learning was done group work during in class time via Zoom. The purpose of this study is to investigate students’ satisfaction with online flipped learning via Zoom by medical students’ learning styles and to explore implication for medical education.

Student satisfaction depending on learning style is summarized in Table 2. Problem solving and understanding, active participation, and self-directed learning attitude significantly presented online flipped learning in the active–reflective learning style, with chi-square scores of χ² =8.18 (p=0.01), χ² =5.45 (p=0.05), and χ² =8.79 (p=0.01), respectively. For sensing–intuitive type, active participation showed a significant difference from other effects of learning (χ² =4.20, p<0.05). For visual-verbal and sequential–global types, no statistically significant difference was discovered among the satisfaction’s scores of learning style.

During the COVID-19 pandemic, various educational institutions executed their academic curricula online via asynchronous and synchronous classes. Medical schools in Korea were no exception. This study explored medical students’ satisfaction with online flipped learning by learning styles. According to the study result, it has been revealed that there are differences in satisfaction of flipped learning by learning styles. There were statistically significant differences within active–reflective types and sensing–intuitive types.

These results are consistent with Abidin et al. [7], wherein active-type students showed significantly higher scores of class satisfaction than reflective-typed students. Likewise, Chae [8] reported that active-type students had higher satisfaction with problem-based learning (PBL). In contrast, Hur and Kim [9] found that reflective-type students were more satisfied with their academic achievement and PBL classes than their active-type colleagues. Kim et al. [10] also showed that reflective-type students had higher satisfaction’s score than those of active-type students. The researcher thought that these different results would be related to the characteristics of online learning, especially synchronous learning through zoom. In other words, because online flipped learning is conducted through real-time videoconferencing in class, there is almost no time for self-reflection. Thus, this method of synchronous learning would be more advantageous to quick-witted and active-type students.

Also, the results of the present study support that of El-Bishouty et al. [4]. They claim that the online environment is suitable for sensory-visual learners and advantageous for facilitating teacher and student communication. The current study reported that sensory-visual participants actively engaged in discussions without dozing off or doing anything else during flipped learning.

This result has a limitation in that it is difficult to generalize because of the limited study sample.. Therefore, follow-up research involving medical students at different year levels from different medical schools in Korea is needed. Over the past 20–30 years, medical education has attained remarkable qualitative improvements and reforms in terms of educational methods. Especially due to the COVID-19 pandemic, online learning using information technology has accelerated, and new concepts of educational methods, including flipped learning, are being implemented. In the future, it is necessary to find the factors that can lead to successful online classes in medical schools.

In the educational sector, learning style is an important concept in understanding the diverse ways in which students process and absorb new information. Therefore, it is paramount that research on learning styles of students be continuously performed, not only for integrating learning process and facilitating knowledge acquirement but also for helping individual students reach their full potential and targeted goals.
