1. Introduction
The COVID-19 pandemic has significantly impacted dental education worldwide. The implementation of distance learning in the context of dental education has created challenges for many dental schools in meeting student competence and training needs. The challenges are rooted to the nature of the dental curriculum, which consists of both theoretical and intense practical training. Dental education combines didactic, laboratory, and clinical psychomotor skill development. The program produces graduates who are clinically competent and independent. Throughout this educational journey, students acquire psychomotor skills while upholding an appropriate level of personal values (including professionalism), as well as the underlying theories and concepts of relevant disciplines. The improvement and development of problem-solving skills, critical thinking, reflective practice, and the capacity to forge dynamic relationships with patients and teams are further components of the journey [
1]. Previous studies addressing dental education challenges during the COVID-19 period included infrastructure, access to pre-clinical and clinical training, the mode of examinations, and graduation requirements [
2,
3,
4,
5].
Many studies from different parts of the world have evaluated students’ attitudes toward, perceptions of, and impact of online education in dentistry during the COVID-19 pandemic [
6,
7,
8,
9]. Although dental students adapted to online learning, they agreed that blended learning could be implemented using innovative education technologies that also consider the education pedagogy [
10,
11,
12]. However, limited studies have explored the perceptions of staff, faculty, and administrators during COVID-19 [
9,
13].
A report from a single-institution study in Denmark during the pandemic showed that both students and faculty members had positive perceptions of online learning. The study was conducted at the beginning of the pandemic [
13]. A qualitative study in a Singaporean dental school highlighted the challenges with online learning; however, the academicians were confident about its future in dentistry education [
14]. Previous studies have explored the perceptions of social science faculty members and students in Jordan regarding online learning during the COVID-19 pandemic [
15]. This study showed that more effort was needed to achieve interactive learning, and the lack of interaction resulted in low student performance, although lecturers agreed that the method of learning could differentiate student performance and help them achieve academic competence. However, whether these results can be replicated in dentistry education is still unconfirmed [
13]. Previous studies on dental hygienist educators have explored the level of personal burnout that may influence teaching efficacy [
16].
A study on the effects of online learning for dental students within different dental schools in seven Asian countries and other parts of the world have demonstrated that blended learning provides better learning efficiency [
12,
13,
14]. The study participants comprised dental students from different regions of Asia, hence they may have had different conditions during the COVID-19 pandemic. The study also had no data on the pandemic’s effect on lecturers. Furthermore, the study contained limited data relating tor dental schools in the Southeast Asian region. Therefore, the aim of this study was to assess the perceptions of faculty members from different dental schools in Southeast Asian countries regarding the implementation of online learning during the COVID-19 pandemic.
4. Discussion
This study focused on lecturers’ perceptions from several dental schools in Southeast Asia regarding the implementation of online learning during the COVID-19 pandemic. The perceptions of online learning, in terms of IT skills and preparation, effectiveness, challenges, and advantages, were compared with participant characteristics. This study was the first to explore the topic in the Southeast Asian region. The study found that the faculty had good IT skills and perceptions of the effectiveness and advantages of online learning. However, after experiencing online learning implementation in their dental schools during the pandemic era, dental faculty members believed that online teaching was not as effective as offline teaching in the context of dental education. This study suggested that the faculty had better perceptions of the advantages and opportunities of online teaching, and recognized that the effectiveness of offline teaching alone was limited. This study also found that the faculty thought that student competency related to the expected learning outcomes would not be achieved better by using only face-to-face teaching.
Online learning utilizes information and communication technologies (ICTs) and has been implemented as a method of dental education for more than 30 years [
17]. Although online courses were not popular in Asia before the pandemic, this study identified that the faculty of dental schools in the Southeast Asian region had experience in online teaching in their schools before the pandemic, and the schools had provided them with training for online teaching. The technology incorporated into teaching enhanced the learning process and was not limited by time and place [
18]. The technology requires equipment to support its operation, which is not cheap; thus, acquiring technology remains a challenge for schools with different conditions of social economy [
19].
The faculty agreed that more preparation was needed when performing online teaching. The sudden change to online learning during the pandemic caused dental schools which had been shut down to switch to live online classes, then pre-recorded classes [
9,
12]. Pre-recorded classes required instructors to spend more time preparing the learning material. However, the faculty agreed that online platforms had the tools to facilitate online classes. They also concurred that utilizing the camera when conducting online classes was important for maximizing interaction and class effectiveness. Student and teacher interactions are regarded as a key design component in online and distance learning [
20]. Some studies illustrated that online learning methods were applicable for theoretical lessons and that for clinical students, it would have limitations for learning the practical or psychomotor aspect when in the laboratory or clinical setting. Furthermore, some faculty members had to maintain students’ self-regulatory behaviors, as well as e-learning motivation in conducting online classes [
21].
In this study, most outcomes focused on a neutral value for the perception of the efficacy of online instruction in dentistry. Regarding online instruction for practical classes and improving student performance, faculty members were at odds. Although clinical learning can also be shifted to virtual learning by using mannequins and virtual reality/augmented reality (VR/AR)-based simulation devices to help gain clinical skills with unlimited reproducibility, there are many challenges for its implementation [
22,
23,
24]. Since 2003, the Academic Centre for Dentistry Amsterdam (ACTA) started the development of VR and force feedback (FF)/haptic for dentistry with several lead researchers [
25]. Developing abilities for some irreversible clinical procedures was the system’s goal. The system may simulate real-life situations that cause users to experience various levels of immersion and involvement, stimulating students’ senses of visual displays, aural, and force feedback [
24]. The development of the system has been shown to offer training that allows users to completely concentrate on the tasks at hand, without the distraction of technical problems [
24]. However, there were limitations to the system’s use for implementation at all dental schools worldwide, including terms of the curriculum, length of study, and system availability. Dental schools must update their hardware and/or software regularly to maintain the implementation process. To date, the results demonstrated that the USA and China exhibited the most publications related to the use of technology [
22]. Implementing this new technology and keeping up with its rapid changes would be very challenging for dental schools in Southeast Asia.
The faculty in this study also concurred that maintaining engagement, resolving technological issues, accommodating students with hearing impairments, time management, and data protection and security are challenges of online learning. Despite these difficulties, the faculty acknowledged the benefits of online learning in terms of time and communication flexibility, low cost, and the chance to attain new skills and tools. Previous studies have suggested that the atmosphere created by online learning should be narrowly targeted, promote in-depth and meaningful teaching and learning, and include students in a more active and collaborative educational experience [
1]. With all the factors related to the effectiveness, challenges, and advantages of online learning, teachers, and students needed to undergo a significant upskilling process that would be innovative and collaborative [
26].
This study found that older faculty members with longer teaching experiences had lower perceptions regarding the IT skills required for online teaching. Previous studies showed that, compared to individuals from Generation Y, faculty members and students from the Baby Boomer generation and Generation X reported feeling less at ease and more anxious when utilizing technology [
27]. Regarding the effectiveness and advantages of online learning, the faculty believed that it could be a better teaching solution than offline learning in dentistry. The faculty in this study agreed on the benefits of using a hybrid or blended learning approach for future teaching. This perception matches with the characteristics of current students who have effective skills and are intuitive in operating modern technology and devices [
10,
28]. In the era before COVID-19, the use of blended learning was limited in many dental schools worldwide, including Southeast Asia [
10]. Compared to the traditional teaching approach, the implementation of a blended learning method could take more work since it requires the right attitude, a large budget, and good learning motivation from both teachers and students [
12]. Improving the computer skills of both students and faculty members at each dental school should also be emphasized [
12]. Communication skills that may be compromised during online learning should also be focused on when designing hybrid classes [
29]. The skills of the faculty in charge of hybrid learning are also significant. More training is needed to improve students’ current educational skills and prepare in advance if similar conditions occur [
12,
28]. Integrating face-to-face and online learning should create a focused environment that supports deep and meaningful teaching and learning, and engages learners in a more active and collaborative educational experience [
1]. The change in the learning method after the COVID-19 pandemic should have been able to maintain the quality of dental students’ education.
This study included one dental school from Indonesia, Thailand, Malaysia, and Vietnam as a representative sample of Southeast Asian countries. This study was limited by the inclusion of only one dental school from each country. The findings are based on the faculty members’ self-reported perceptions, which can be associated with a self-reporting bias based on their feelings when they completed the questionnaires. Furthermore, the answers may be influenced by the circumstances in each country regarding the pandemic. The inclusion of more dental schools to participate in the study would provide more information about faculty perceptions in the Southeast Asian region. However, the study received good responses from the faculty members of the dental schools that participated in the study, and the results based on the dental schools from each country were similar. The differences were mainly based on the age, teaching experience, and academic levels of the participants.
