Evaluation of Online Pedagogy among Higher Education International Students in China during the COVID-19 Outbreak

Online-based pedagogy in teaching and learning has become the order of the day in this era of the COVID-19 outbreak. It became necessary to ensure that the pandemic did not cause a time gap in learning amongst students. Online learning involves the use of virtual platforms in the form of mobile and web applications for teaching and learning. Learning can take place using audio, visual and audio-visual means. Online learning has previously been used as a supplement for face-to-face interaction; however, it became the sole means of teaching during the pandemic and a novel development. A total of 273 international students across China engaging in online classes during COVID-19 outbreak volunteered to respond to the online questionnaire were involved in this study. The results of the descriptive statistic for the study were presented using charts and line plots. The research revealed the demographic details of the respondents, Wechat as the most prevalent platform used, perceived effectiveness of online classes, and other factors such as interest, engagement, participation, and problems encountered during online teaching among international students in China. The shortcomings that this research has brought to light are expected to enhance better online learning experiences post-COVID 19 in China and other parts of the world.


Introduction
Online pedagogy among international and indigene students in China became a necessity after the Corona Virus outbreak, which was first reported in Wuhan, Hubei Province, China in December 2019 (Dai et al., 2020;Gong et al., 2020). It was the only means to ensure continued learning (Hayes et al., 2020) among higher education students and it was embraced and adopted by the Chinese Government Education Board across China to adhere to disease control measures of social distancing and avoidance of gatherings and to avoid a time gap in the academic calendar. The spring semester slated for resumption by 17th February 2020 was postponed, and online classes were adopted across China (Huaxia, 2020). Huaxia (2020) reported that the commencement of online classes as a control of the COVID-19 pandemic also promotes digitalization and informatization of teaching, such as the use of new applications such as the Rain Classroom app. Prior to the COVID-19 outbreak, which eventually turned to a pandemic, online learning in China and in most countries of the world had only been used as a supplement to face-to-face learning (Hew & Cheung, 2014;Sobko et al., 2020) and not as a sole pedagogy approach.
With the prevalence of the pandemic and with predictions (Robert et al., 2020) that it could linger on for months and even more, online learning through various virtual platforms with a learning environment that allows the learner to learn and acquire knowledge in interactive mode (Deka & Jena, 2017) is gradually replacing chalk and board classroom learning. China has over time made considerable achievements in terms of internationalization of higher education (Yang, 2014), through government funding (Frezghi & Tsegay, 2019) and availability of various scholarship programmes such as the China Scholarship Council (CSC) scholarship, Belt and Road scholarship, Confucius Institute scholarship amongst others. It is germane to evaluate online pedagogy among international students since they are mostly from different educational backgrounds, while some could have previously engaged in online learning, others may not. Demographic details such as nationality, current degree, major and province were considered in the study. A previous study by Ruthotto et al. (2020) revealed that responses to virtual learning vary based on several factors. It is, therefore, crucial to evaluate the online pedagogical environment and factors such as learners' engagement, interest, associated problems and effectiveness as perceived by learners in the course of learning.

Online-Based Pedagogy
Pedagogy refers to the theory and practices of teaching in an educational context (LaVelle, Lovato, & Stephenson, 2020). Technological advances hold a great deal of promise as online pedagogical tools (Kern, et al., 2004), and there is also a need for a multimedia specialist to develop a sound online-based pedagogy (van Rooij & Zirkle, 2016). Online-based pedagogy is a kind of pedagogy that primarily revolves around technology-enhanced learning. Hill and France (2020) stu-died innovations in pedagogies; technology-enhanced learning was one of the eight kinds of innovative pedagogies.
The unique event of the COVID-19 pandemic has not only made technology-enhanced learning necessary; it has launched the world into "Digitalization and Informatization of teaching" and has showcase Online-Based Pedagogy as the only available teaching and learning option in this era (Charles et al., 2020). Several studies have shown that online-based instruction has successfully helped in learners' engagement facilitation, enhancing student learning, professional development and effective teaching with learning resources (Farhan et al., 2019;Sanders-Smith et al., 2016;Sun, 2016;Terry et al., 2018). Despite the successful uses of online-based instruction, there are still some problems encountered and negative impacts on learners. By considering the context of 919 (K-12) students taking online courses, Zheng et al. (2020) conducted research examining the impact of learner, instructor and course-level factors on online learning. The study found that online discussion negatively affected students' learning outcomes except if it was supported by project-based assignments and higher-level knowledge activities. Similarly, a systematic review on blended learning in Malaysia, which comprises face-to-face and online learning component instruction, revealed the challenges encountered; teachers and students find the use of technology for teaching and learning difficult and the problem of providing suitable instructional technology by the educational institution (Rasheed et al., 2019). Additionally, there are some risks associated with internet use, such as excessive engagement in specific online activities and other problems the learner can be exposed to (Orsolya et al., 2020).
Evidently, previous studies have shown the positive and negative aspects of online-based instruction and pointed to the fact that it should not be used as the only pedagogy in learning instruction. However, teaching and learning in the COVID-19 era depends solely on online-based instruction, and it is imperative to evaluate online-based learning during the COVID-19 in comparison to previous literature claims and seeing through the lens of an international student in China.

Learner's Participation & Engagement in Technology-Enhanced Instruction
In enhancing teaching and learning processes, learners' participation is essential (Haniya & Paquette, 2020). The study by Haniya and Paquette (2020) examined learners' massive online course participation, using participation patterns such as "Advanced, Balanced, Early, Limited, and Delayed Participation", and found two major factors that drive learners' participation (motivations and barriers), and their impacts vary with respect to the learners. In another study in which a social network analysis research technique was adopted, 57 college-level students participated in online learning activities that were assisted by assigned moderators; the study revealed that student participation had significant influences on interaction attractiveness (Xie, et al., 2014). In the context of measuring learners' participation in technology-enhanced instruction, it can be said that learners can choose to be passive or active in learning engagement. Learner engagement is an indispensable requirement for learning and vital to academic achievement in online learning (Gallagher et al., 2016;Omar et al., 2012), and Haron et al. (2017) defines it as an active learner in learning activities. In the use of technology instruction in enhancing learners' activities, the virtual platform has to be efficient because the quality and type of online teaching can promote meaningful learners' engagement (Christopoulos et al., 2018;Eric, 2020;Warford, 2014). Dougherty and Andercheck (2014) studied the use of a virtual platform (Facebook) to engage learners in a large introductory course and revealed that the Facebook platform proved effective as a powerful tool for engaging learners.
Furthermore, in a systematic analysis review, Haron et al. (2017) found that in an e-learning community, collaborative learning that can foster interaction that will in turn lead to participatory engagement must comprise interactions of learners, interaction of educators and learners, interaction with content, and self-reflection. However, a book chapter raises a concern about learner engagement in technology in terms of digital software, socioeconomic and race-related achievement gaps (Lo & Miller, 2020). Based on previous studies, learners' participation and engagement in technology-enhanced instruction must be considered alongside the type of digital software and socioeconomic and race-related factors in which this research clearly fills this gap.

Learner's Interest Sustainability in Online Classes
"Interest is a powerful motivational process that energizes learning" (Harackiewicz et al., 2016). Reflecting on the learning experience of a first-year otolaryngology residency student, a decline in the applicants for otolaryngology residency was revived by stimulation strategies that sustain learner interest (Hu, 2019). On this note, sustaining learner interest in online classes requires some strategies, either from the learner, from the teacher or in kind of network use (Choi & Park, 2014). Interest is powered by motivation in a learning process and is subject to change through learning activities (Nakazawa & Ikeda, 2011). To this end, the learning activities in a normal face-to-face learning process differ from online classes (Nakamura et al., 2012), and how can learner activities on online classes be sustained? Recently, research carried out on "towards recommendation using learners' interest in social learning environment" rightly identifies fewer studies that were based on this research context (Lamia et al., 2020). Lamia et al. (2020) analyzed the learning environment and proposed a social interaction (users-users and users-resources)-based learning environment.
This study explored some indicators to measure learners' interest in online classes, which can help to identify factors that can sustain learners' interest during teaching and learning and recommendations for better ways to sustain learners' interest in online-based environments. Thus, the purpose of this research is to identify international students engaging in the online classes during COVID-19 outbreak demographic information and their study locations, online learning platforms adopted, and which is the most prevalent platform; the medium of pedagogy adopted; perceived effectiveness. To know maybe the adopted pedagogy encourages learners' participation, engagement and sustained learner's interest during teaching and learning. Besides, to know the problems encountered during online teaching and online pedagogy student preference. As the research outcome can strengthen the educational stakeholder such as school administrators, ministry of education to prepare for better online learning experiences for post-COVID 19 in China and other parts of the world.

Participants
The population for the research comprises international students in China engaging in online class during the Covid-19 pandemic. Purposive sampling was used to select international students that were in China at the time of the study.
This was because aside engaging in online classes; they were experiencing the outbreak first-hand. The questionnaires were administered online and sent to international students across China through academic groups, colleagues, and friends. The final samples were those that eventually responded to the questionnaire. A total of 273 international students responded to the questionnaire.

Design and Procedure
The instrument used for the study was the Pedagogy Measure in Virtual learning Questionnaire, which was constructed by the researchers. The questionnaire comprises items on demographic information of students (nationality, current degree, major and province), type of platforms used for online learning, medium of instruction (audio, visual or audio-visual), student engagement during online learning, problems with online learning, perceived effectiveness of online learning and sustained interest during online learning. The learner's engagement section asked questions relating to the learner's activities during the learning process with a Yes/No response format. Learners' interest during the online class considered items to determine how engrossed learners were in the online classes with a 4-scale response format. The perceived effectiveness section of the questionnaire compared the effectiveness of online learning to in-class learning in factors such as communication, sense of community, convenience, participation and interaction, meeting individual needs, aiding understanding and providing better explanation as perceived by the learners. The response formats (see Table  The questionnaire was an online form that was distributed and filled electronically by respondents. The collection of data for the study spanned from March through May 2020.

Results
The demographic information of the respondents in the study. Table 1 shows that 53 countries were represented in the study, with the majority (30) from Africa, followed by Asia (19) and Europe and North America with 2 each. Figure 1 shows that 113 (41.39%) of the respondents were undergraduates, 89 (32.6%) were master's students and 71 (26.01%) were doctoral students. There were more undergraduates than masters than doctor students. Figure 2 shows that 108 (39.56%) respondents were science majors, 18 (6.59%) were in arts, 14 (5.13%) were in humanities, 73 (26.74%) were in engineering, 46 (16.85%) were in social sciences and 14 (5.13%) were in medical sciences. This implies that there are more international students in the sciences than engineering, social sciences, art, humanities, and medical sciences. This could be because the country of those international students requires such kind of talent, so they choose this major. Figure 3 shows those 20 provinces, 3 municipalities and 1 autonomous city represented in the study. Figure 4 shows that several platforms were used for online teaching, ranging from common platforms such as zoom, dingtalk, classin, wechat, tencent, QQ, skype, rain classroom, superstar and chaoxing. Other applications used rarely were MOOC, Big Blue Botton Virtual class, BBB (Better Business Bureau), Tang class, Twitter, Instagram, E-mail, Coursera, Welink, Ice, Sakia, Zjoooc.cn, Ingke and Microsoft Team. Several people also indicated that they adopted more than one of the applications, with some using approximately 4 simultaneously. The distribution of application usage shows that the most widely used platform is WeChat, followed by tencent, Zoom, Dingtalk and QQ with equal proportions, Skype and classin. Other applications accounted for 8.07% accumulatively. WeChat is the most widely used platform because WeChat is the main social platform widely used across China.
The result represented by Figure 5 shows that 234 (85.71%) had their classes using audio-visual, 26 (9.52%) had classes using audio only and 13 (4.76%) had classes using visual means only. The audio-visual is a generally more accepted medium of teaching because more senses are involved, and it helps to sustain interest and attention. Table 2 shows that for communication, the majority of the respondents (156, 57.14%) perceived that online teaching was less effective than in-class teaching; 91 (33.33%) also agreed that the two forms of teaching were equally effective, while only a few (26, 9.53%) considered online teaching to be more effective than in-class teaching. This could be attributed to the fact that communication in online teaching is not very logical and sequential.    For sense of community, the majority of the respondents (156, 57.14%) perceived that online teaching was less effective than in-class teaching; 91 (33.33%) agreed that the two forms of teaching were equally effective, while only a few (26, 9.53%) considered online teaching to be more effective than in-class teaching. This could be because online teaching does not require any social interaction and therefore does not render any form of community sense.   For offering convenience, 83 (30.4%) of the respondents perceived that online teaching was less effective than in-class teaching, 106 (38.83%) agreed that the two forms of teaching were equally effective, and 84 (30.77%) considered online teaching to be more effective than in-class teaching. The result shows that an almost equal number of respondents agreed to online teaching and in-class teaching to be effective and less effective for offering convenience to students while studying. More respondents consider online teaching and in-class teaching to be equally effective.
For promoting participation and interaction, the majority of the respondents (147, 53.84%) perceived that online teaching was less effective than in-class teaching; 90 (32.97%) agreed that the two forms of teaching were equally effective, while 36 (13.19%) considered online teaching to be more effective than in-class teaching. This could be because online teaching does not require any social interaction and therefore does not promote participation among learners.
For meeting individual needs, the majority of the respondents (142, 52.01%) perceived that online teaching was less effective than in-class teaching; 94 (34.43%) agreed that the two forms of teaching were equally effective, while 37 (13.55%) considered online teaching to be more effective than in-class teaching.
This could be because the same pedagogy approach is delivered through online teaching, which gives no room for individuals and their specific needs.
To aid in better understanding, the majority of the respondents (138, 50.55%) perceived that online teaching was less effective than in-class teaching; 104 (38.1%) agreed that the two forms of teaching were equally effective, while only 31 (11.36%) considered online teaching to be more effective than in-class teaching.
To provide a better explanation, the majority of the respondents (139, 50.91%) perceived that online teaching was less effective than in-class teaching; 99 (36.26%) agreed that the two forms of teaching were equally effective, while only a few (35, 12.82%) considered online teaching to be more effective than in-class teaching.
The results in Table 3 show that the majority of the respondents (202, 73.99%) ask questions during online classes, the majority (226, 82.78%) answer questions during online classes, and the majority (247, 90.48%) participate in activities given by teachers during online classes. Quite a number of the respondents 167 (61.17%) also communicated with their peers during online classes.
All these findings indicate that the majority of the students participate and are actively engaged in the online learning process.
The results in Table 4 show that the majority of the respondents ( Figure 6. Preference for medium of learning. (46.89%) would prefer a combination of the two modes of learning. This implies that more people prefer combinations of in-class and online. This could be because of the problem associated with online learning, but if combine, some of the problems could be easily solved with in-class learning, thereby providing an optimized learning process.

Discussion
Online-based pedagogy in teaching and learning has become the order of the day in this era of the COVID-19 outbreak. It became necessary to ensure that the pandemic did not cause a time gap in learning amongst students, in online pedagogical environment and factors such as learners' engagement, interest, asso- (2019) that in 2018, approximately 63,000 international students received scholarship from the Chinese government.
The evaluation of online platforms adopted for online teaching by international students in China during the COVID-19 pandemic, as this context of the research is very unique, it has provided insight into the various virtual platforms that can be adopted for learning and teaching processes (see Figure 4 for review). This finding confirms recent research on "virtual read-out", i.e., only virtual forms of teaching and learning available during the COVID-19 pandemic (Charles et al. 2020). The most prevalent platform used was WeChat. For the medium of pedagogy adopted, the medium adopted is perfectly digitalization and informatization. The findings support Huaxia (2020), who found that digitalization and informatization of teaching has been promoted in the era of the COVID-19 pandemic. Most international students had their classes using audio-visual, followed by audio only and visual-only. The findings confirm Espasa et al.'s (2019) research, which found that learners preferred video channels over audio or written channels in an online learning environment.
Regarding the effectiveness of online pedagogy as perceived by international students, communication during online teaching was less effective than in-class teaching, as communication in online teaching is not logical and sequential, sustaining learners' attention during online class needs to employ strategies such as variation in communities' network structures (Choi & Park, 2014). Similarly, the sense of community of online teaching was perceived to be less effective than in-class teaching because there is no social interaction. This finding confirms prior research that explained that online-based learning requires the addition of project-based assignments and higher-level knowledge activities (Zheng et al. 2020), with learners having a sense of community. Another indicator for perceived effectiveness as used in the research is offering convenience; quite a number of international students consider online teaching and in-class teaching B. F. Komolafe et al. to be equally effective. The majority of the international students perceived participation and interaction, meeting individual needs, aiding better understanding, and providing better explanation during online teaching to be less effective than in-class teaching, which could be because the online classes were during a unique period when the teachers and learners were under environmental pressures. Thus, this result supports (Haniya & Paquette, 2020) that motivations and barriers are factors that influence participation and interaction in online classes.
Another barrier encountered is the adoption of the same pedagogy in delivering online teaching, which gave no room for learners' specific needs.
However, the reality of international students was done on participation and engagement, as shown in Table 3 probably because they need to engage online, which is against their perception about online classes, as shown in Table 2, that perceived participation and interaction in online teaching was less effective than in-class teaching. The majority of the respondents ask questions during online classes, give answers to questions during online classes, take part in activities given by the teachers during online classes and quite a number of the respondents also communicate with their peers during online classes. Thus, these findings on promoting meaningful learners' engagement in the virtual platform were in accordance with (Christopoulos et al., 2018;Eric, 2020;Warford, 2014). Lamia et al. (2020) rightly identified fewer studies that were based on students' interest in online learning. The results on the sustainability of international students' interest during online classes during the COVID-19 pandemic reveal that learners' interest is sustained because many of the respondents reported that they would participate in online classes even when there are other options. A future study could examine various activities carried out on the virtual platforms that made them look forward to the next online class. Even though international students were excited about online classes, they still prefer face-to-face interaction with an online class.
For the problems encountered during online teaching, the major problems encountered were increased distraction, difficulty in paying attention, less motivation, less social interaction and technical issues, with technical issues being the most prevalent . This finding supports prior research that reported that technical issues were encountered by learners and teachers (Rasheed et al., 2019) and excessive engagement in specific online activities such as gambling, video gaming, and watching pornography during the COVID-19 pandemic that can cause distraction (Orsolya et al., 2020). Finally, considering the medium of learning that students prefer after their exposure to online learning, the larger percentage of international students, as shown in Figure 6, prefer a combination of in-class and online learning, probably because of the problems associated with online learning. This is in line with Zheng et al. (2020), who found that online discussion negatively affected students' learning outcomes unless it had been supported by project-based assignments and higher-level knowledge activities. This finding hence suggests the possibility of combining in-class and online classes in the post-COVID-19 period.

Conclusion
In conclusion, as the global community begins to adjust to the post-COVID19 new normal life and the reality that it will be around for a while as humans carry out their activities, it becomes imperative for educational institutions to adopt measures that address the shortcomings of online education platforms and ensure that effective learning experiences and outcomes are achieved. While the shortcomings may be partly due to the use of the virtual learning environment in full deployment during an emergency situation, its adoption has enabled educational practitioners to experience first-hand the advantages and shortcomings that this research has brought to the light. The use of virtual learning will continue to be very relevant in the new normal life; therefore, educational practitioners need to keep abreast of strategies and approaches to improve virtual delivery of teaching and learning without sacrificing quality and content. On the other hand, teachers will be placed on new challenging pedestals as they will be faced with demands for innovation and mastery in the use of the virtual learning environment in the post-COVID19 new normal life. With the findings in this research, teachers and learners in higher institutions and other stakeholders in education such as Ministry of Education, school administrators should prepare ahead for a transformative learning environment that would involve an integration of both virtual and traditional learning platforms to enhance learning experience as well as promote good learning outcomes in learners.
