According to the study’s ﬁndings, e-learning has a favorable and statistically signiﬁcant impact on students’ ﬂexibility


Introduction
The World Health Organization has identified COVID-19 as a global epidemic with adverse consequences in many parts of society [1,2].Despite the tragic events of COVID-19, the exceptional circumstances created a new platform that led to the development of elearning and digital education [3].The disease outbreak has halted educational processes at the graduate level, leading to poor exam results and negatively impacting students' future employment.Update models were implemented for educational systems in countries [4].
As a result of the rapid expansion of new educational technologies over the past few years and the emergence of a revolution in this field, new technologies have emerged as one of the most important and memorable components of the educational process [5].When it comes to designing teaching methods and learning outcomes, these technologies have a lot of potential [6].On the other hand, e-learning uses modern technology to access educational programs available on the Internet [7].E-learning is no longer restricted to online lectures, virtual classes, and pre-prepared content due to the rapid rise of information and communication technologies.The arrival of the Internet of Things (IoT) has impacted earlier models of e-learning, transforming it into a more participatory and appealing approach [8].In all regions of the world, the IoT communication paradigm is changing students' learning processes and creating an ecosystem that accelerates interaction between teachers and students.
The IoT is a large platform comprised of an array of things containing electronics, computers, sensors, and networking elements that allow for a high degree of satisfaction in integrating necessary services around the world [9].This is accomplished by constantly interchanging data between producers, consumers, and other computing devices [10].Everything in the IoT communicates with other things through the Internet infrastructure, making the IoT a worldwide distributed system [11].Everything has an Internet Protocol (IP) address in the IoT that can communicate and interact with any other object, both virtually and physically [12].The IoT's primary goal is to connect everything on the planet to provide complete global access to the Internet.According to Gartner, by the end of 2021, around 25 billion gadgets will be connected through the IoT [10].The many IoT-based devices determine the strength and superiority of this platform that it supports.

•
Providing a practical framework for IoT-based e-learning;

•
Determining the impact of the IoT on e-learning systems;

•
Evaluating the performance of the IoT-based education process through a questionnaire.
The rest of the article is organized as follows: related work to e-learning is reviewed in Section 2. The potential of the IoT as a robust framework for e-learning in undergraduate and graduate education is described in Section 3. the results and benefits of using IoT are analyzed in Section 4. Finally, conclusions and suggestions for future work are given in the final section.

Literature Review
Yang and Yu [17] have described a ZigBee/GPRS wireless network technology system, sensor technology, embedded technology, web-distributed software technology, and database technology.This method uses three interconnected networks and connects several test terminals, servers, and clients, which promote the rapid flow of information and facilitate the actual implementation of distance learning.Teaching results indicate that the IoT can improve students' educational performance and teachers' teaching models.Therefore, a hot spot is considered in modern educational systems, which should be paid special attention to.
Moreover, Vharkute and Wagh [18] have designed a standard distance learning structure that combines different e-learning applications with the help of the IoT.Student satisfaction increases due to this technology-based approach, which improves the relationship between the student and the teacher while providing a cost-effective education.This training system uses GSM and GPS technology to deliver a suitable and optimal training model.Students will benefit from adopting this strategy in school buses with computer learning facilities since it will help them succeed.Lack of attention to quality is a significant weakness of this method.Furthermore, Cornel [19] has presented an IoT-based methodology for establishing online virtual labs, a fundamental prerequisite for any education system to be high-quality and competitive in the global marketplace.This model demonstrates that practical lessons may be conducted using a remote system.Students can now take advantage of IoT capabilities to access the resources they need for various real-world investigations.As a result of this method's lower costs and higher performance of new electronic modules, it allows for the development of several web services that include data processing and communication via the Internet.By connecting an Arduino platform to the Xively web service, this technique demonstrates how to use the IoT in a practical setting.Unfortunately, this technique has low privacy.
In addition, Abbasy and Quesada [20] have suggested the most significant and expected effects of the IoT on higher education, including theoretical analysis and a statistical investigation.It examines the most important and most relevant academic and statistical outcomes of IoT in the e-learning paradigm, particularly in the context of learning and management variables.Things such as over communication, teamwork, and research opportunities distinguish this work from the rest of the field.Unfortunately, one of the shortcomings of this strategy is that it does not emphasize IoT applications in the sphere of education.
Zahedi and Dehghan [21] have discussed IoT-based e-learning in various aspects in which the main advantages of IoT in e-learning and the importance and necessity of using IoT in this regard are stated.Existing challenges and current solutions are discussed and analyzed.The results indicate that IoT will soon be a fundamental process in new technologies in e-learning, and by creating the proper infrastructure and implementing it optimally, universities will benefit significantly from IoT-based online learning models.
Of course, the appropriate frameworks for universities wishing to adopt IoT must also be comprehensively and adequately analyzed.Implementation techniques are not considered in this method, which is regarded as one of the ambiguities and the main drawbacks of this method.
"Moreover, Ying and Jiong [22] offer the Virtual Reality-based Education eXpansion (VREX) training platform, a combination of online and offline models, to improve the curriculum and teaching experience in higher education.Virtual reality (VR) is the essential component of this platform.Aiming to enhance curriculum efficacy in an immersive environment by allowing students to have an intuitive understanding of abstract knowledge that is difficult for teachers to express, it has been used to improve the effectiveness of the curriculum in an immersive environment.The slides are converted into VR sceneries in this method, allowing students to observe and study in a real but utterly virtual environment.VREX also offers a distributed model that will enable students to participate in the interactive learning process from any location at any time.The combination of augment reality (AR) and mixed reality (MR) is not supported by this approach, which is a disappointment." Finally, Lin and Yu [23] proposed a model that used wearable spherical video-based virtual reality (SVVR) and compared their design with a map guide group that used tablets to learn library functions.Both groups performed a similar test of prior knowledge, assignments, situational interest, and cognitive load.The results show that the wearable VRbased model can produce a higher degree of challenge and novelty and enhance learning and teaching.Educational systems that use SVVR have good potential to change the way students learn, improve traditional education, and increase students' understanding of content.Adoption of new technologies, the time required to complete tasks, and performance effectiveness are some of the issues not addressed in this model.
Table 1 summarizes the comparison of previous related literature in e-learning using new technologies, including the IoT.

Proposed Method
This section shows how to improve the learning process based on new educational models.The proposed new learning method is based on the IoT in e-learning.As a result, the following hypothesis is put forth: Hypothesis 1.The IoT-based e-learning has a considerable impact on flexibility.
Hypothesis 2. The IoT-based e-learning has a substantial influence on the learning experience.
Hypothesis 3. The IoT-based e-learning has a significant effect on educational productivity.Hypothesis 4. The IoT-based e-learning has a significant effect on the quality of education.

Problem Statement
The e-learning system allows students to complete their classes on their devices such as tablets, smartphones, laptops, etc.They will also be able to attend classes online and whole participatory learning [24].
Implementing the IoT as a new factor in e-learning can facilitate interaction between students and teachers and objects (devices).This interaction means that devices can communicate with each other and with people.

IoT e-Learning
Due to the high efficiency of the IoT in education, students enjoy many benefits.This technology allows them to use all models of education, including personal, dynamic, and participatory.In addition, interacting with many objects connected to the web, students access unlimited resources at any location and time and receive content beyond the classroom.Universities can use the IoT in automation, energy management, research experiments, etc., for their members [25].The general idea of using the IoT in e-learning is to create an environment for acquiring knowledge in a modern and efficient way according to the needs of students.The IoT has many advantages in e-learning, including: Existence of intelligent interactive class.Increase students' creativity by using updated tools.Comprehensive reporting of student activities.
The IoT allows teachers to improve their performance in the online learning environment.This technology supports the classroom by improving teaching methods and processes, increasing teaching resources, and saving costs.Learning resources on devices, such as digital books, are much more interactive.It is worth noting that there is a constant need for up-to-date technologies in educational activities, such as high-speed wireless networks or adequate bandwidth for sharing audio and video files [26].
IoT devices in the proposed model communicate with each other or with other students' devices, and any device can request training information.To gain user control over online class transactions, a common key is assigned to devices by the BC-based model [27].
This system checks the owner and distributes the shared key on the devices.IoT devices communicate without any central reference if the key is valid, and centralized architecture becomes meaningless [28].
Blockchain (BC) provides a platform for IoT-connected devices to manage protected data.
The main strengths of using BC alongside IoT are: O Reduce costs by communicating directly and without intermediaries with the customer.

O
Reduce the risk of accidents by providing trust between IoT devices.O Accelerate real-time transactions.
A combination of IoT with educational content can develop students' skills in the fastest method.The IoT is employed in the core learning process, including listening to courses, taking notes, and writing, to guide students to use resources for amusement and extracurricular communication actively.Sensors exist on everyday items and have their own data transmission channels, storage, and applications.They constitute a vast sensor network that enables the IoT to monitor and safeguard people through objects.Based on the information obtained from the nodes, teachers might develop an interactive website utilizing network infrastructure and educational ideas.Students have the chance to select and download their course at any time and place according to the progress of learning to best implement personalized learning.During the online test, professors design and submit numerous test questions, and students can choose the test questions according to their level of expertise.The IoT-based interactive class seems to bring higher satisfaction to learners.
The IoT does a lot to increase students' creativity, using mobile phones, smartwatches, tablets, and other connected devices to generate and express ideas instead of the traditional, simple methods of the past.In the age of massive information, it forces the mind to be creative so as not to ignore much of the existing data and turn the formerly trivial content into valid and original data and information.This has led to a dramatic increase in creativity in new education systems in which technologies have become prevalent.
A student's academic achievement, including grades, is included in the student performance report in the traditional education system, and the performance score is not considered to be an indicator of their activity-based performance.Furthermore, traditional models are incapable of determining the state of each student throughout numerous activities in the learning environment.
Student performance may be evaluated automatically with the advent of the IoT, which can find temporal and geographical trends and deliver critical information to teachers and parents continually.The data included in the active nodes of the learning environment is used to generate the required patterns.It has also been suggested that a cloud-based storage mechanism be implemented to administrate IoT-based activity data properly.

IoT for Examinations
According to the properties of the IoT world, which applies both the one-to-many and the multi-to-multi communication models, all items in our surroundings are connected and generate new signals every second.Local things can also communicate with other virtual or real objects through an inter-network architecture compatible with the Internet.The term "real time" refers to the fact that students can live in a real-time environment from 7 a.m. to 12 p.m., seven days a week, and access primary educational and technical data or information.
This IoT architecture model provides an increased chance to deploy other intelligent devices such as drivers, networks, and servers that can receive IP addresses and cloud infrastructure, which allows for the processing of large volumes of data and surveys much more quickly than previously possible.The smart devices in this design, which have a variety of capabilities for observation, monitoring, communication, and decision making, have the potential to revolutionize the training and evaluation model completely.
During the tests, the data sent from the sensor nodes are examined and processed to detect anomalies.The teacher receives data that identifies which students are misbehaving to send cheating alerts to these suspicious students or remove them from the exam.Figure 2 shows the proposed model for e-learning on the IoT.All the steps of forming a class and holding an exam take place within this framework.
A collection of IoT devices, including cameras, microphones, and wearables, collects data from students in real time, which is then stored and analyzed.Wireless technology such as Bluetooth, ZigBee, and other similar protocols is used for the transmission of data from sensors to receiving devices.The IoT hub links student gadgets to cloud storage, which allows for the storing and processing of data on a larger scale.The collected data are processed in real time in the cloud using machine learning (ML) algorithms, allowing faster decision making.The teacher obtains the outcomes on their unique profile and adjusts their educational approach during teaching or exams.

Cheating online exams is usually only easy with the help of someone who is stationed somewhere in the room to answer online questions.Today, of course, the use of 360-degree cameras is common, but there are no recorded results that prove the effectiveness of these cameras.New models must be used to address this vital weakness and increase confidence in online testing.The most critical of these is the collection of important data from the student along with webcam data, such as electro encephalo gram (EEG), electro cardiogram (ECG), skin resistance, and performance analysis.For example, how does a student react when a difficult question arises?This type of data can be easily obtained by closely Monitoring online exams is very difficult because students are not in a centralized location, and there are different ways to cheat on online exams compared with face-to-face exams.Platforms have been designed in which online observers use webcams to monitor student behavior.Where observers watch several webcams, but unfortunately, there is no tool to record the parameters of other individuals taking part in the tests.

ML has been utilized in various activities, including monitoring systems during teaching and exam periods, in a variety of situations.A sophisticated e-learning process can benefit from ML, which provides powerful tools for ongoing quality improvement.In the course of an exam or real-time teaching process, the proposed ML model is employed to detect an uncommon event.It is predicted that it will assist teachers and supervisors in improving decision making and preventing online learning errors.
Clustering is employed in this design as one of the standard machine learning approaches that may be performed without supervision and is used to group data points.It is a widely well-known technique in the field of statistical analysis.Clustering is a technique for organizing data points into groups based on each data point's traits and attributes.Clustering is used with a specific data set to organize data points into groups [29].
The K means algorithm is one of the most extensively used clustering algorithms, and it is also utilized in this design to allocate a group to unlabeled data.Every group is determined by computing the distance between a data point and the core of the group, and each data point is allocated to one of the groups defined in this way [30].This technique is rapid and scalable, and its primary application is the identification and analysis of anomalies [31].

Data Collection
Students' online questionnaire information was collected from April 2021 to June 2021.Three IoT and e-learning experts performed the pre-test.Table 2 shows the characteristics of the people participating in the survey separately.According to Table 3, the survey was measured on a Likert scale from 1 (completely disagree) to 5 (completely agree).Out of 600 surveys submitted for students, 280 responses were returned, of which 263 were helpful, so the sample size (43.8%) is acceptable.

Performance Assessment
According to the available values, the structures are in a state of reliability.Therefore, internal compatibility is approved.In addition, by examining the mean of variance, the validity of the instrument was also proved.Given the values in Table 4, the AVE results, in which all variables have an AVE value above 0.50, are acceptable.If the variance inflation factor (VIF) is 3.0 or lower, it is impossible for multiple lines to be threatening [32].Of course, the appropriate VIF standard was assumed to be 5.0 in previous work, but recent studies show that this level is considered very high.
Table 5 shows the discriminant validity as part of the testing process.Discriminant validity was performed to validate how a latent research variable is independent of other items.Discriminant validity is ideal when the mean variance of an individual latent structure has a tremendous amount of multiple square correlations compared with other structures [33].The results indicate that all the variables under study have discriminant validity values.
The small sample size used in this study is a significant drawback of the design.Although there were just a few respondents, useful identifying information was obtained despite many individuals.Based on quantitative analysis, it has been demonstrated that items connected to online education can be quantified in a reasonable and trustworthy manner.The proposed approach has the potential to be utilized to collect essential information that can be transferred to online learning environments.Figure 3 compares the views of 200 professors who have used the IoT world with devices connected in the classroom to those who have never experienced it.The professors were confronted with a complete review of the underlying reasons because there were so many various sectors of online education to consider.The findings indicate that teamwork and reflection are the weakest conceivable areas in IoT-based online education, while motivation and interactivity are the most effective.These areas are obvious focal points that should be considered in discussions about expansion and development, as well as educational policy and planning.
The results in Figure 4 clearly show that the score of each section has a significant relationship with the work experience of professors.Younger professors have a more positive outlook than older professors.
Following that, development and expansion plans and other resources can be developed from the results.By examining qualitative findings, we can broaden our understanding of online teacher education conceptualizations.The findings of this combined study can be used to better understand the relationship between faculty online teaching and student outcomes, as well as to identify significant topics for future research and policy development.The results in Figure 4 clearly show that the score of each section has a significant relationship with the work experience of professors.Younger professors have a more positive outlook than older professors.Following that, development and expansion plans and other resources can be developed from the results.By examining qualitative findings, we can broaden our understanding of online teacher education conceptualizations.The findings of this combined study can be used to better understand the relationship between faculty online teaching and student outcomes, as well as to identify significant topics for future research and policy development.

VR training models are confronted with a variety of difficulties, including hardware issues.On the other hand, this paradigm brings about a shift in education through the use of novel educational procedures and methodologies.For the future, by using dynamic teaching methods and the integration of technology in education, it is possible to make learning content more appropriate while also providing students with a more comprehensive learning experience.Educational content can be combined with VR to develop a more effective educational environment.Furthermore, it is recommended to create an intelligent student authentication system based on IoT tools, which will improve e-learning.
