Nowadays, the COVID-19 pandemic has resulted in an unprecedented interruption of traditional education in the universities and educational centers. Consequently, traditional education has switched to virtual education during COVID-19. Despite virtual education, experienced teachers still have a positive attitude toward traditional education. In traditional education, which is teacher-centered, plenty of information is transferred to the students in a specified time (1), while, nowadays, in a virtual atmosphere, a new educational environment has been created based on person-centered education (2). In a virtual atmosphere, students usefully prefer to use devices such as mobile, computer, and so on, and can have more convenient access to information (2). Therefore, to improve the standard of education and increase the learning quality in a person-centered approach in a virtual atmosphere, it is important for the teachers to become familiar with a new approach of virtual education (2). Also, the acquisition of necessary skills will help the students to study independently and participate actively in the learning process (2). It is doubtful if we can fulfill all the needs of students in the virtual education system as we could with face-to-face interactions in the traditional method. It seems that the flipped classroom education strategy can facilitate the student learning process during the coronavirus crisis (3, 4) The flipped classroom is a new educational approach that reverses the traditional education method (3). In this method, at first, the students receive digital educational materials provided by the teacher at home. Then, teachers and students engage in classroom activities to discuss and solve the problems (3, 4). Today, in the coronavirus crisis, the virtual flipped classroom is used. Virtual flipped classroom activities can facilitate e-learning education under technology (2, 5). As part of the virtual flipped classroom-based educational strategy, the first activities will take place outside of the classroom, in the form of asynchronous e-learning educations, while the second part of the activities will take place inside of the classroom, in the form of synchronous e-learning educations such as web conference, video conference, and virtual classroom (5). Asynchronous e-learning education is a type of education that involves teachers and students participating in the process of teaching and learning separately. Synchronous e-learning education is a type of education that involves both teachers and students to participate in the process of teaching and learning simultaneously.
