Determining Factors Affecting Acceptance of E-Learning Platforms during the COVID-19 Pandemic: Integrating Extended Technology Acceptance Model and DeLone & McLean IS Success Model

: Online meeting platforms have been widely utilized during the COVID-19 pandemic due to the current shift from traditional learning. However, the acceptance of the different online meeting platforms for e-learning has been underexplored. The purpose of this study was to determine the factors for acceptance of an online learning platform among students during the COVID-19 pandemic. A total of 500 senior high school students voluntarily participated to answer constructs under the Extended Technology Acceptance Model (ETAM) and Delone and McLean IS Success Model. Several latent including user interface (UI), perceived ease of use (PEU), perceived usefulness (PU), information quality (IQ), system quality (SQ), behavioral intentions (BI), and actual use were analyzed by Structural Equation Modeling (SEM). The results indicated that PEU was found to have the greatest on actual use (AU), followed by UI and SQ towards PEU, which subsequently led to BI and AU. Finally, IQ was found to have a signiﬁcant effect on PU, which led to BI and AU. The level of student acceptability considers the ease of use, user interface, system quality, information quality, leading to a positive behavioral intention for actual use. With that, it would be of best interest to consider the factors that would lead students towards accepting the platforms utilized and therefore the current education system. Moreover, this will lead to their acceptance and promote learning even with the COVID-19 pandemic. Finally, the model construct can be applied and utilized to analyze the online learning platforms in other countries.


Introduction
Worldwide education has been suspended due to the COVID-19 pandemic. Due to this pandemic, schools, universities, and other higher educational institutions temporarily paused face-to-face educational learning. The education learning is mainly delivered through online meeting platforms such as Blackboard Collaborate, Microsoft Teams, and have examined the responsibility of family support towards the technology adoption process of the students [10]. These studies integrated extended TAM, which is intended to affect intern convictions, perceptions, and intentions of students' family support, which has positively estimated the ease of use, usefulness, attitude to tablets as well as the intention of using tablet computers among students [10]. In addition, extended TAM is used to identify several factors that impact the behavior of users while utilizing a mobile library application [11]. The positive impact of the behavior considered perceived usefulness and perceived ease of use addressing the system quality [11]. Furthermore, TAM is commonly combined with several theories such as DeLone and McLean IS Model [12].
According to Hsu et al. (2014), the DeLone and McLean IS Success Model is used for IS research papers as a valid model and framework for variables that are complex dependent [12]. In addition, this model is developed and proposed to information systems to study what the user behavior is and explain it through the utilization of technology [13]. Moreover, this model is still widely used by researchers and journalists of the service industry because the comprehension and understanding about Information System Success are continuously progressing. Additionally, if a proper understanding of the model is achieved, it would help to show the importance of the system. It can even serve as the foundation for the decisions to the said systems [14]. The significance of the DeLone and McLean IS Success Model will contribute greatly as help to create new ideas and strategies that will further aid the students in developing countries on the adaptation to the use of e-learning platforms [15]. Therefore, the current adaptation of e-learning due to the COVID-19 pandemic should be explored. Specifically, the acceptance of students in utilizing online meeting platforms for e-learning.
The purpose of this study was to determine the factors contributing to the acceptance of an online learning platform among students during the COVID-19 pandemic. Extended Technology Acceptance Model (ETAM) and Delone and McLean IS Success Model were integrated to determine the causal relationships among the selected factors. This study contributed to the highlighting factors affecting online meeting platforms' loyalty among Filipino senior high school students during the COVID-19 pandemic. The result of this study could be utilized to give better experiences during E-learning in the COVID-19 pandemic. With the sudden shift of traditional learning to online learning, it would be best to consider the factors for acceptance of students toward different online meeting platforms. This will result in a better experience, thus enhancing learning among students during the COVID-19 pandemic lockdown. The model construct can also be applied and extended to analyze the online learning platforms in different countries.

Literature Review and Hypotheses
During the COVID-19 pandemic, only a few studies were conducted out from the Philippines. Moreover, only a few have used the Extended Technology Acceptance Model and the Delone and McLean IS Model. Hence, extending the research to other fields based on technology with a larger sample of study potentially appears to raise the current understanding regarding the use of IT applications [16]. From Figure 1, the extension of the Technology Acceptance Model included information quality, system quality, and user interface from the Delone and McLean IS Model. Following previous studies [3,9,[16][17][18][19], the Delone and McLean IS Model could promote antecedent in measuring the actual use of a system through behavioral intentions. This is because system quality has a positive impact on e-learning [3], information quality can measure the performance and information towards e-learning [17,18], and the user interface is an antecedent of perceived ease of use that determines the interactivity among users [16,19]. Therefore, the relationship of the latent is presented in Figure 1. that determines the interactivity among users [16,19]. Therefore, the relationship of the latent is presented in Figure 1. The connection of system quality and perceived ease of use were not empirically shown, as stated by Al-Fraihat [3]. According to [3], it is argued that the lack of support system quality is often aided to have a beneficial impact on the system and the understanding of an e-learning system among users. The ease of use should be considered for utilization of a system. Furthermore, given the presence of communication features, such as forums, messages, and email, data from messages and forums can convey the views and personal data that a student may not want to be recognized from the outside world through internet service providers. Therefore, providing details before using the technology or the system will improve their understanding and affect their attitudes significantly towards the overall utility of the system [3]. Thus, we hypothesized that: Hypothesis 1. System quality had a significant direct effect on perceived ease of use.
Information quality is a key and essential factor in determining the performance of information and the e-learning environment. The information has an important role in achieving learning objectives and the severe challenges that have occurred as a result of low information quality [17]. In addition, Wu [18] observed the relationship between information quality and perceived usefulness is significant. Consequently, we can conclude that enhanced information quality in the e-learning environment can contribute to a growing degree of perceived usefulness. Thus, we hypothesized that: Hypothesis 2. Information quality had a significant direct effect on perceived usefulness.
The most powerful feature of an online meeting platform is that it remains an interactive platform with various people. These experiences influenced students to keep using online meeting platforms [19]. According to Mohammadi [16], the user interface is where a person takes control over a technology or system. Moreover, it was figured out that learners are attracted by the usage of the features. The features would eventually improve the user's attractiveness as well as the reduction of the waiting and response time of the materials to load [16]. Thus, we hypothesized that: Hypothesis 3. User interface had a significant direct effect on the perceived ease of use. The connection of system quality and perceived ease of use were not empirically shown, as stated by Al-Fraihat [3].

User interface had a significant direct effect on the perceived ease of use.
Furthermore, perceived usefulness and perceived ease of use are combined towards technology acceptance. According to Mohammadi [16], perceived ease of use is when an individual accepts that utilizing a system would be free of effort. It describes the behavior of an individual towards their interaction, which will serve as the mediator to the actual use of the system [16]. Moreover, perceived ease of use has been utilized to measure the end-user's behavioral intention of using a technology [9]. Behavioral intention is defined as the outcome of the behavior executed by an individual based on the individual's experience. With that, if the perceived ease of use of the online meeting platforms is greater, the intention of its usage is more beneficial. Hence, we proposed the following: Among the other models concerning the acceptance of technology, the Extended Technology Acceptance Model is utilized towards technology acceptance. It introduces the concepts of perceived usefulness (PU) and perceived ease of use (PEU) to measure the intentions of the user to use technology [9]. According to Zheng and Li [10], TAM indicates that the two variables (PE and PEU) influence the attitude of the students to use a new application, system, or technology. With that, the attitude of the students influences their behavioral intention to use. According to Mohammadi (2015), perceived usefulness is described as an important factor of intention, in which it persuades the users to accept a more advanced and user-friendly technology [16]. With that, if the perceived usefulness of the online meeting platforms is greater, the more effective is the intention towards its usage. Thus, we hypothesized that: Hypothesis 6. Perceived usefulness had a significant direct effect on the behavioral intentions of the user.
Behavioral intention is defined as the motivational factors that influence a person to execute or not execute the behavior in the future. Moreover, according to Botero et al. [20], behavioral intention has a positive effect on actual usage. This connection has been proven in research covering technologies in education. Thus, we hypothesized that: Hypothesis 7. Behavioral intention had a significant direct effect on actual use.

Questionnaire
An online questionnaire (Table 1) was distributed through Google Forms since it is not possible to conduct surveys due to the General Community Quarantine (GCQ) of the COVID-19 pandemic in the Philippines. In accordance with other studies [21,22], an online questionnaire would suffice with the data collection for the study. The respondents were asked to answer the questions with the extent of their knowledge and experience. With our theoretical framework, a self-administered questionnaire was developed in our study to determine factors that affected the loyalty of online meeting platforms among Filipino senior high school students during the COVID-19 pandemic. The questionnaire consisted of 8 sections, which included demographic information, system quality, information quality, user interface, perceived usefulness, perceived ease of use, behavioral intentions, and actual use. A total of 32 questions adapted from different studies covered all factors. A test run was done utilizing 50 respondents to check the validity of the questionnaire. Following the suggestion of Hair [23], the overall result got a Cronbach's alpha value of 0.976 (acceptable ≥ 0.700). Thus, the questionnaire was considered valid and was distributed. The demographic information consisted of questions regarding gender, school year, hours consumed in an online class (per week), and tuition fee (per year). A 5-point Likert scale was utilized in this study to measure all latent variables. The 5-point Likert scale had a measure of strongly disagree as 1 and strongly agree as 5.

Participants
The participants were among senior high school students from any school in the Philippines. The participants voluntarily answered the questionnaire, which took about 15-20 min to accomplish. A total of 500 respondents were collected for this study. Hair [23] suggested that 500 respondents would suffice for a framework considering 8 or more latent. Additionally, the respondents were asked to fill out a consent form before answering the survey. Convenience sampling was utilized in this study wherein we made the link available for anyone to answer between October 2020 to December 2020. Specifically, the link of the Google form was distributed through social media platforms for all senior high school students. Therefore, any student from different universities had equal opportunity to answer with their prerogative. Table 2 represents the descriptive statistics of the senior high school respondents in which the profile of the respondents was discussed; however, names were not included to protect privacy. Based on the results, 79% of the results show the percentage of grade 12 students that participated in this study while 21% of the results were grade 11 students. Moreover, results show that there was a greater percentage of students within a range of 31-40 h (29.5%) for their online classes. The tuition fee measured the socio-economic status of the respondents, wherein it was within the bracket of middle to higher economic status. The higher economic status was seen to be 50.3% of the respondents with more than 70,000 Php of tuition fee per year. Following which is 28.4% in the middle status of 15-70,000 Php and 21.4% of the lower socio-economic status.

Statistical Analysis
Structural Equation Modeling (SEM) is a quantitative tool that is commonly utilized in advertising and institutional behavior analysis for instrument validation and model testing [27]. In addition, it can be used for evaluating the relationship between the numbers observed and the latent variables [28]. According to Teo and Noyes [29], SEM can be used for assessing and analyzing the intentions and behavior of the user on the usage of technology. In the study, SEM was utilized to explain and estimate the factors that influenced senior high students to choose an e-learning platform and their acceptance. to enhance the model fit [23]. Figure 3 demonstrates the final SEM analysis for evaluating the factors affecting online meeting platforms' loyalty.

Results
technology. In the study, SEM was utilized to explain and estimate the factors that influenced senior high students to choose an e-learning platform and their acceptance. Figure 2 demonstrates the initial SEM with indicators on the analysis for evaluating the factors affecting online meeting platforms' acceptance and loyalty. As seen in the model, three indicators had low significance, therefore modification indices were applied to enhance the model fit [23]. Figure 3 demonstrates the final SEM analysis for evaluating the factors affecting online meeting platforms' loyalty.   Demonstrated in Table 3 are the results of the descriptive statistics for the constructs utilized in this study. Table 4 shows the reliability and validity of the constructs. Average Variance Extracted (AVE) measures the discriminant validity of the constructs. A construct with an AVE greater than 0.5 indicates a degree of validity in the construct [23,30]. Cronbach α and Composite Reliability (CR) both measure the internal consistency between each set of items in a construct with an acceptable value of greater than 0.700 [23,31]. All constructs used in this study had values greater than 0.800, and thus were considered acceptable. Table 3. Indicators statistical analysis.

[30] and Steiger [31], values higher than 0.80 for TLI, IFI, CFI, GFI, and AGFI f and a value less than for 0.07 RMSEA are considered good model fit [32,33]. Based on Table 5, all the model fits passed the cut-off, indicating that the model was a good presentation of the data.

Discussion
The current study integrated the Extended Technology Acceptance Model and Delone and McLean IS Success Model to evaluate the factors affecting online meeting platform loyalty among Filipino senior high school students during the General Community Quaran-

tine (GCQ) of the COVID-19 pandemic in the Philippines. A Structural Equation Modelling
(SEM) approach was utilized in this study to analyze the interrelationship among the latent variables. The variables considered were system quality (SYS), information quality (IQ), user interface (UI), perceived usefulness (PU), perceived ease of use (PEU), behavioral intentions (BI), and actual use (AU). With that, an online questionnaire was utilized through Google Forms. As a result, a total of 500 data samples were collected. Through the Structural Equation Modelling (SEM) approach, the impacts of these factors were examined.
The Technology Acceptance Model (TAM) was composed of perceived ease of use and perceived usefulness, which were the core variables of this model [10]. With that, Mohammadi [16] claimed that perceived usefulness is affected directly by perceived ease of use. As the result of the current study suggests, SEM indicated that perceived ease of use had a significant direct effect on perceived usefulness (β = 0.786 and p = 0.001). Meanwhile, perceived ease of use serves as a mediator towards behavioral intentions. Perceived ease of use had no significant effects on students' intention from the study of Mohammadi [16]. In contrast with that, the findings of the current study indicate that SEM indicated that perceived ease of use had a significant direct effect on the behavioral intentions of the user (β = 0.451 and p = 0.001). From the constructs, the students assessed that the ability of a system to be user-friendly, making users aware of any changes in the time of session through emails and social networks, the possibility of recording each session and uploading it in the database of the e-learning system for the absent users, and the overall usefulness were the main contributors to perceived usefulness and behavioral intentions [11,16]. The findings could be interpreted that the ease of use towards online meeting platforms makes it easier for students to study through remote learning. The results also suggest that online meeting platforms are very useful in this time of the pandemic. However, this may be challenging for students with limited access to the internet. According to Abuhassna et al. [34], students would tend to find information online, utilize online learning like platforms, and communicate with others to aid their learning. The challenge of digital inequalities appears when students need to gain information with a weak internet connection. Therefore, interactivity, receptive learnings, and demonstrations may be a challenge for students with weaker internet connections.
The user interface has a major effect when it comes to the perceived ease of use on technology (β = 0.656 and p = 0.001). This is supported by the results of the study from [35]. Perceived ease of use dictates if users decide if they are going to use technology for shortor long-term periods [36]. Additionally, the constructs indicated that users tend to be more at ease if they find an interface easy to use. Uploading pre-prepared content such as PowerPoint presentations, image files, documents, live-streaming, video content from a webcam, digital whiteboard, and screen and audio sharing were the main contributors to perceived ease of use. These findings were supported by the studies of [16,37], wherein they stated that the flexibility, time-efficient, responsiveness, functionality, and reliability helped in improving the user's attractiveness as well as the reduction of the waiting and response time of the materials to load [16,38]. Based on the data given in the results, Structural Equation Modeling (SEM) indicated that user interface has a strong direct effect on perceived ease of use. It means that the students are highly affected by the online meeting platform's user interface. However, this may only be applicable for students with moderate to strong internet connections. Therefore, it will be a challenge to perform reflective practices, reviews, apply creativity, innovation, and participations. Therefore, the user interface should be considered when being utilized in the current e-learning for students.
Furthermore, the behavioral intentions of a person play a significant part in the actual use of modern technologies [38]. The Technology Acceptance Model (TAM) indicates the behavioral intention of users forms the actual use of technology (AU). Additionally, when the behavioral intention is strong, the perception of information and communication technology (ICT) as a tool of teaching-learning should be reflected in its actual use of the Internet to teach [37]. In addition, the correlation between behavioral intention to use modern technologies and actual use involves experimentation to correct the high emphasis on behavioral intention, otherwise called the problem of the "bottleneck" [39,40]. Budu et al. [40] claimed as well that the outcome of their research shows that behavioral Intention positively impacts e-learning system application (actual use) [38]. The coefficient in the result of their study was 0.483 (p < 0.000), and thus, behavioral intention is supported. Based on the results of the current study, Structural Equation Modeling (SEM) indicated that behavioral intention has a significant direct effect on actual use (β = 0.590 and p = 0.001). Therefore, student's intention towards using an e-learning platform can be related to the interface and ease of use to have positive intentions of using the platform.
Perceived usefulness influences the attitude of students in using a new system or technology, then the attitude of students eventually affects their behavioral intention [10]. Additionally, online meeting platforms' effectiveness, productivity, and improvement in academics, as well as, studying asynchronously are the main contributors of perceived usefulness. In the study conducted by Islam [41], the researchers found that perceived usefulness is recognized as an unimportant factor in the use of e-learning. Moreover, according to Park et al. [42], the result of their study indicated that perceived usefulness had no significant direct effect on the behavioral intention of students. However, the studies mentioned did not have a pandemic when it was conducted [41,42]. Based on the results of the current study, the SEM indicated that perceived usefulness has a significant direct effect on behavioral intentions (β = 0.302 and p = 0.001). This is because the current set-up of distant learning utilizes internet access to different platforms for continuous education. It was seen that there were high indicators of the system being useful in the current COVID-19 pandemic, and that students would rather utilize the online platform than risking infection, causing significance to the variable. This is also applicable for students in different countries by having e-learning as the substitute to traditional learning in the interests of safety.
According to Alsabawy et al. [17], system quality and information quality were considered as high factors in the successful design of e-learning systems. Moreover, the result of the study of Rafique et al. [11] indicated that system quality is a worthy interpreter to both perceived ease of use and perceived usefulness. However, Wu [18] claimed that system quality has no significant positive influence on perceived usefulness, but it has a significant positive influence on perceived ease of use. Furthermore, Wu [18] also claimed that information quality has a significant positive influence on perceived ease of use. Based on the results, Structural Equation Modeling (SEM) indicated that system quality had a significant direct effect on perceived ease of use (β = 0.569 and p = 0.001). Therefore, students would tend to accept e-learning platforms that are convenient and easy to use.
According to Kim and Lee [43], system quality is one of the major factors that affect the perceived ease of use for how it determines how users will accept a system for its overall performance. Like the constructs considered in this study, adaptability, reliability, usefulness, and responsiveness are factors that highlight how students will be able to accept the different e-learning platforms. In addition, information quality was also found to have a significant direct effect on perceived usefulness. Information quality will determine if the information that will be given by the system is verified and accepted by the user, hence, it will affect the user's satisfaction, the intent of use, and perceived usefulness [44]. Additionally, accuracy, uniqueness, completeness, relevance, accessibility, precision, and informativeness of the information given is a major factor to the user's perceived usefulness [45]. Therefore, information quality had a significant direct effect on perceived usefulness (β = 0.184 and p = 0.001).
Apart from the significant direct effects, it could be interpreted that the online meeting platforms are useful as a medium to deliver information. It is inferred that the qualities of information that online meeting platforms deliver are enough and provide complete information, which make the students believe that the information provided is useful and helpful. These results could be considered for students' acceptance across the world. Different platforms may be utilized by different countries, that is why this study considered general constructs to measure student's acceptability. The level of student acceptability considers the ease of use, user interface, system quality, information quality, leading to a positive behavioral intention for actual use. Since the world is currently suffering from the COVID-19 pandemic, countries are in lockdown and therefore continue with the e-learning platforms. With that, it would be of best interest to consider the factors that would lead students towards accepting the platforms utilized and therefore the current education system. Moreover, this will lead to their acceptance and promote learning even with the COVID-19 pandemic.

Theoretical Contributions
According to Yakubu and Dasuki [15], the Structural Equation Modeling is a collection of methods and techniques that are commonly used to analyze and eventually explain the connection between multiple variables using a series of equations and computations. Additionally, SEM can analyze the most complex linkages between latent factors [46][47][48][49][50][51]. Because of this, SEM can be used for analyzing the factors on why the users use technology in the first place [52,53]. With this current pandemic, it is not a surprise that almost everyone will depend on the usage of technology, especially in the sector of education. In this study, the Structural Equation Modeling was utilized in such a way that it explains how Filipino senior high students will choose a specific online meeting platform by analyzing each individual factor and its relationship with each other. Moreover, the theoretical contribution of this study will be beneficial for both students and teachers when it comes to continuous learning, especially during the pandemic. By being able to have ease of use, interactivity for user interface, system and information quality among the platforms being utilized would lead to a positive behavioral intention for actual use.

Practical Implication
Due to the COVID 19 pandemic, traditional classroom learning has now progressed to online education, resulting in an eventual shift of all sorts of various educational institutions worldwide, which many Filipino students find difficult to adapt to [9]. The practical implications of the study provide insights into important issues and strategies that will broaden the significance of online meeting platforms among Filipino senior high school students. Online meeting platforms should enable communication and coordination between students to be expressed, thus affecting the satisfaction of learners [37]. The findings of the study can be useful for government officials and non-profit organizations to help and manage Filipino students with unequal learning opportunities from low-income communities that cannot access the new technologies used in online learning. Moreover, teachers and students could have a more efficient way of conducting online learning that would benefit both by utilizing a platform applicable for their liking and needs.

Limitations and Future Research
However, this paper still has limitations of some sort. Due to the utilization of online surveys, there may have been biases towards respondents with access to proper internet only. Future research can collect more data in a group and consider the differences in age, grade level, and gender. This may have an effect on the perception of the different online meeting platforms being utilized. Moreover, the prior experience of online learning may also be included for measurement for assessing the acceptance of e-learning platforms. Different students may have different perceptions and comfort with the online meeting platforms. Second, the different subjects taught were not considered. This may also be an extension by future researches as the different subjects are taught in different manners and approaches. Even the instructors or teachers may also be considered as a variable in this study. The delivery of instructions and lessons to the students may also be different. Third, this paper only studies the factors affecting online meeting platforms' loyalty among Filipino senior high school students. Junior high school students and teachers can also be future participants. Future studies can fully examine all the students' and teachers' loyalty among online meeting platforms. Lastly, the current study is only limited to the Philippines. Therefore, future studies can examine different countries to know different factors affecting online meeting platforms' loyalty among students around the world.

Conclusions
Online meeting platforms have been widely utilized during the COVID-19 pandemic. The need to continue developing the education system was challenged during the COVID-19 pandemic. Specifically, it was seen that the sudden change in the mode of delivery from traditional learning to fully online became a challenge. The challenge led to the idea that online learning was considered an emergency education. With that, online learning highlighted a lot of issues with regard to sustainable learning. Different strategies came about to be developed as the new normal continues. The investment to promote and sustain the new normal mode of delivery for education could be promising with the proper communication tool to deliver the proper education needed. With established platforms and mode of delivery, online learning could eventually be considered as a mode of learning even after the COVID-19 pandemic. This option would lead to the adaptation and the extension of the sustainability goal (SDG4), growth and sustainability for education in the future. Following the suggestion of Steinberger et al. [48], no students will be left behind. Therefore, the need to assess the acceptance of e-learning platforms by students may be a start in determining sustainable education that may affect the future of e-learning.
Considering this, the purpose of this study was to determine the factors contributing to the acceptance of an online learning platform among Filipino students. Structural Equation Modeling was utilized with 32 indicators among different latent. The user interface, perceived ease of use, perceived usefulness, information quality, system quality, and behavioral intentions to actual use were the variables considered and were all found to be significant. Among the 500 respondents of Filipino senior high school students gathered online through convenience sampling, it was seen that perceived ease of use (PEU) was found to have the greatest significant effects on perceived usefulness towards actual use (AU). Following that is the user interface having a significant effect on PEU, and behavioral intentions to AU. Students want to utilize a system that is easy to use and for the interface to have high functionality and flexibility. The level of student acceptability considers the ease of use, user interface, system quality, information quality, leading to a positive behavioral intention for actual use. Since the world is currently suffering from the COVID-19 pandemic, countries are in lockdown and therefore continue with e-learning platforms. With that, it would be of interest to consider the factors that would lead students towards accepting the platforms utilized and therefore the current education system.
