Proposed V-E-learning Model: Applying V-Model to Ensure the Quality of E-Learning System Implementation at Higher Education Institutions (The Case of Dar Al Uloom University-COVID-19 Pandemic Effect)

Since March 2020, CORONAVIRUS (COVID-19) pandemic has affected many sectors, including education sector at the global level and at the Kingdom of Saudi Arabia. Preventative procedures have been taken, including suspending teaching and training for K-12 and higher education and moving to use distance education as an alternative to face-to-face education, with the continuation of the Corona pandemic, the Ministry of Education decided to consider the e-learning (distance education and blended education) as a strategic alternative to overcome crises threatening the educational process . With the widespread use of e-learning platforms in the Kingdom of Saudi Arabia, the interest of the quality of e-courses increased more than before. Therefore, this study proposes a model for ensuring the quality of e-learning and e-courses in higher education institutions and developing a set of evidence and suggested performance indicators that help those responsible for quality management to verify and validate the adherence to these standards. Dar Al-Uloom University was chosen as a case study of what was implemented during the Corona pandemic and the extent of the university’s commitment to this standards to ensure continuous improvement and raise the level of performance related to the e-learning system and its e-courses.

private, beginning Monday, (7/14/1441 AH) (9 March 2020) with the activation of virtual classrooms and distance learning during the suspend period. The Ministry of Education also developed a wellstructured guide for universities to help them to develop effective solutions for the current situation, ensuring the continuation of the educational process and enabling students to perform learning activities, exams and achieve learning outcomes (Ministry of Education, KSA, 2020). The efforts of the Ministry of Education led to the universities' success in dealing with the current situation and completing the educational process in the second and summer semesters of the academic year 2019-2020, The Ministry decided to start the first semester of the year 2020-2021 in universities through distance learning and blended learning. The Ministry of Education developed the Madrasati platform (https://schools.madrasati.sa/) for K-12 as a national project that provides its services to millions of users, including students, teachers and parents, this platform is considered a great achievement by the Ministry to ensure the continuity of education in The Kingdom of Saudi Arabia. Table (1) provides statistical data on e-learning and distance learning in Saudi universities for the second semester 2019-2020. These statistical data reflect the efforts of those universities in activating the elearning and distance education systems and the high readiness of universities in the Kingdom of Saudi Arabia in dealing with the risks facing the educational system. In the Kingdom of Saudi Arabia, and by a decision of the Council of Ministers on 01-13-1439 AH (03-10-2017), an independent center was established under the name of "National elearning Center" and its board of directors is chaired by the Minister of Education. The National elearning Center has developed standards for controlling the quality of e-learning in K-12 and higher education and training bodies, taking into account the integration with the competent authorities, and it was built according to a study of the most famous international standards, and through polling the opinions of beneficiaries, and holding workshops for education officials, and they were reviewed by local and international experts (National elearning Center, KSA, 2020) . The next section introduces global standards for the quality of e-learning in higher education institutions and the standards developed by the National elearning Center in the Kingdom of Saudi Arabia . Dar Al-Uloom University DAU-LMS has provided the e-learning system for several years, this system has been used as one of the learning resources that benefit students. An electronic page is available in the e-learning system for each course of that includes electronic contents for learning, electronic assignments, and some electronic exams, DAU-LMS is used as one of the means of communication between Student and faculty member. The availability of DAU-LMS in advance, helped Dar Al Uloom University to transfer directly to provide e-learning and distance learning. However, attention is now focused on improving the electronic content provided to students and adhering to the quality standards of the e-learning system and the quality of e-courses. Table (2) provides statistical data on e-learning and distance learning in Dar Uloom University for the second semester 2019-2020. These statistical data confirm the university's commitment to implementing e-learning during the Corona pandemic. These statistical data were collected on a weekly basis, that is, after the end of each academic week, to monitor students' commitment to attendance and interaction. It can be noted that the number of ecourses and the number of student entry registrations for these courses in the College of Business Administration, the College of Law and the University Preparation Program (UPP)are more than in other colleges, because in these colleges provided e-learning for all courses, while other colleges provided practical learning in presence with apply the precautionary measures to prevent the spread of Corona virus.

B. Quality Assurance of E-learming Systems
Quality systems aim to ensure continuous improvement. Therefore, e-learning systems must be evaluated and continuously improved to ensure that high-quality learning processes are applied and to improve student learning outcomes by applying quality standards that consider all stakeholders 'expectations in the e-learning process (Schreurs and Al-Huneidi, 2012) . With the wide spread of elearning as the main system in distance learning and as a basic supporter of traditional education through blended learning, this attracted great interest by higher education institutions and researchers to develop and apply quality standards for e-learning based on the best practices to improve the level of performance and provide interactive learning for learners through e-learning environments which achieves the desired learning outcomes. There are also many studies that have presented frameworks and standards to ensure the quality of elearning, Hadullo  The above-cited quality standards share a wide range of e-learning quality assessment standards. The most important common standards can be identified with the following components (1) institutional support (2) course development & Structure (3) teaching and learning (4) student support (5) faculty support (6) assessment & evaluation (Insung Jung, 2010). This study relies on these common standards to ensure the quality of e-learning and on the QM standards to ensure the quality of e-courses, and aims primarily to adhere to the standards of the National elearning Center in the Kingdom of Saudi Arabia to develop a proposed model using the Model V methodology that aims to ensure the quality of elearning using national and international standards which is called V-E-learning Model.

C. Using V-Model to Assess E-learning Quality
The V-Model was introduced by Paul Rook in 1986 and was first used in Germany for use in product development and testing for government defense projects (Awotar and Sungkur, 2018; Durmuş, et al., 2018), the name of V-model refers to the v-shaped, where the stages of the model are designed in the shape of V, the phases on the left have a corresponding phase of activity on the right. The V-Model is used in project management, software development, quality assurance, and configuration management. The V-Model is considered one of the internationally accepted models such as ISO/IEC 12207 or ISO 9001 (Roy A. Boggs, 2004) . What distinguishes this model from other development models is that it focuses on the testing procedures from the beginning for each stage of the project and then the Since the e-learning system consists of several main components, and each of these components is linked to development stages that are governed by a set of quality standards discussed above, the V Model has been relied upon to determine the requirements for providing and developing each of these components (Verification), and on the opposite side of each stage, evaluate the extent of compliance with the readiness requirements and the extent of compliance with the quality standards of this component (Validation). Because of the merging of quality standards with V model, this study proposes a title "V-E-Learning Model" for a proposed model that helps evaluate the quality of e-learning systems.

III. RESEARCH METHODOLOGY
The research methodology based on content analysis method which includes (1) analysing the content of research papers related to quality standards of E-learning system in HEIs, (2) review the reports and procedures of the official authorities in the higher education sector to reduce the spread of the Covid-19 pandemic (3) review experiences of applying the V-Model in developing and testing technical and information systems in various fields (4) Analysis of user requirements for those who are responsible for e-learning in Dar Al Uloom University. This methodology aims to achieve the following research objectives: 1. Determine the quality standards for e-learning systems in higher education institutions and the requirements to achieve these standards (verification process). 2. Determine requirements for testing compliance with quality standards for e-learning systems in higher education institutions (validation process). 3. Propose a model to ensure the quality of E-Learning system implementation at higher education institutions based on V-Model (verification -validation model). The proposed model called (V-E-learning Model), the letter "V" referred to V-model, the letter "e" stands for the word "electronic". The proposed model is based on common e-learning quality standards which are extracted from cited researches, the model consists of two basic sides, the left side to define the requirements of achieving e-learning quality standards (verification), and the right side to test the compliance with these standards. Figure

A. V-E-Learning Requirements analysis (VERIFICATION)
The verification side in V-E-learning is responsible for determining requirements e-learning quality standards which consist of six standards. Each of these standards includes a set of requirements and they work together to ensure a quality e-learning environment and help achieve the learning outcomes expected of students.

Institutional Support
The success of the e-learning environment depends on the vision, mission, and goals of the educational institution based on clear plans, policies, and procedures to achieve this success (Martin Debattista, 2018; D. Masoumi and B. Lindström, 2011). The educational institution shall establish a governing body with expertise in the field of e-learning that is accountable and ensures the provision of a highquality e-learning environment (D. Masoumi and B. Lindström, 2011;Frydenberg J., 2002). The educational institution is committed to providing the technical infrastructure that plays a critical role in raising the level of quality and access to e-learning by users. In addition to providing financial support for the management and maintenance of e-learning systems and user training (Insung Jung, 2010; Hadullo, Oboko and Omwenga, 2017). The standards of the National elearning Center defined institutional support according to the criterion of "Leadership" by setting responsibility and governance for the department responsible for the quality of e-learning and setting strategic and operational goals consistent with the vision and mission of the educational institution (National elearning Center, KSA, 2020).

Course Development & Structure
This phase focuses on institutional policy and procedures that ensure the quality of course development processes, course materials and learning activities in e-learning (Insung Jung, 2010). Faculty members and curriculum supervisors in the educational institution must develop the course content that is appropriate for the e-learning environment, especially distance learning, and that high-quality content be available interactively via the Learning Management System (LMS) that helps students achieve the intended learning outcomes, raise their motivation to learn, and achieve Students' satisfaction with the e-learning system (Chawinga, 2016). The proposed model in this research is based on the QM Standards "QM Higher Education Rubric, Sixth Edition", which measure the quality of electronic courses (Quality Matters, (QM), 2020).

Student Support
The educational process in face-to-face learning and e-learning is concerned primarily with studentcentrality, and in e-learning and distance learning, more attention in this aspect is to provide support in various forms to enable the student to present his high potential and raise his motivation towards learning, which helps to achieve the intended learning outcomes instructional support, academic support, technical support, administrative support, psychological and social support (

Faculty Support
One of the most important criteria for the quality of e-learning is the support provided to faculty members to perform their duties in a manner that achieves the goals of the educational process . The National elearning Center has set a standard for "Qualification and Support" for practices related to the development and training of faculty members and learners to enable them to present their tasks in the field of e-learning (National elearning Center, KSA, 2020) .

Assessment & Evaluation
The Assessment and evaluation process in e-learning is always the focus of discussion among educators, especially educators, who see that this process does not have credibility in evaluating students' performance in the e-learning and distance learning environment, Others argue that the evaluation process in e-learning faces problems such as literary plagiarism, security issues, accessibility, and identification (Laurillard D., 2002; Wahlstedt A., Pekkola S. and Niemelä M., 2008). Therefore, there should be a great focus on evaluation tools and methods used in e-learning and ensuring the quality of the process to present evaluation results that are credible, reliable, and fair. However, the evaluation process determines the student's mastery of the intended learning outcomes, they must be compatible with educational content and learning activities (Hadullo, Oboko and Omwenga, 2017) . Evaluation methods in e-learning can take different styles, either directly evaluated by teachers using assignments, tests, electronic discussions, and students' electronic portfolios. On the other hand, the criteria for judging the student's performance through evaluation methods must be clear and consistent with institutional policies and announced in advance to all students, as well as delivery dates and providing appropriate feedback to students at the appropriate time ( . The National elearning Center has also set a standard of "measurement and evaluation" for practices that enable the learner to monitor his performance. The faculty member has also been able to measure the performance of learners and analyze their needs to adapt teaching methods to these needs and measure the level of progress of the educational process through all types of evaluation and feedback methods (National elearning Center, KSA, 2020) .

B. V-E-Learning Testing Process (VALIDATION)
Validation process in the proposed model aims to determine requirements, evidence and KPIs for validating compliance with quality standards for e-learning system. The validating process is a continuous process that begins with the beginning of planning and implementation of the e-learning project, for each stage of the e-learning quality standards verification process is matched by the validation phase, as shown in Figure (1). When starting the validation process, the reviewers use the tools suggested in Table (3) to validate the extent to which the quality standards of e-learning are met and to provide proposals and recommendations to improve the quality of the e-learning system. Based on the results and the recommendations of the reviewers, those responsible for e-learning develop plans that ensure continuous improvement of the effectiveness and quality of the e-learning system at the university. Table (3) clarifies the proposed activities that help to validate compliance with the standards (validation process), which includes a set of evidence, performance indicators and user satisfaction. • Students' satisfaction with organizing and structuring e-courses.
• Beneficiaries' satisfaction with the LMS and virtual classrooms. • Percentage of courses that were evaluated based on QM standards and achieved advanced levels.
• Average Beneficiaries overall rating for organizing and structuring e-courses on a five-point scale in a semiannual survey.

IV. DISCUSSION
The purpose of this study was to propose a model to ensure the quality of E-Learning System Implementation in Dar Al Uloom University as one of private higher education institutions in KSA. The university began implementing national and international e-learning quality standards, and this study seeks to participate in achieving this goal. Below, the proposed model is discussed on the status of Dar Al Uloom University. Institutional Support, The e-learning unit is linked to the higher management at Dar Al Uloom University and has a direct relationship with the Information Technology Department to ensure higher coordination between them, which led to the provision of a strong academic and technical structure that is strengthened through a special budget for e-learning, in addition to the policies and procedures that target all stakeholders. The university began implementing national standards for e-learning and partnered with the Quality Matters Organization (QM) to ensure the application of good international practices, the process of reviewing the quality of all e-courses based on these criteria began. Course Development & Structure, A learning management system (LMS) has been used at Dar Al Uloom University for years to provide educational materials, receive assignments and electronic tests, and monitor student attendance. As a result of the impact of the Corona pandemic, Dar Al Uloom University provided Microsoft Teams program to activate virtual classrooms and enhance interaction and communication between students and faculty members. The process of developing e-courses is organized through clear and publicized policies and procedures, and a unified template for those courses is presented based on QM standards. The process of developing e-courses is reviewed periodically based on these criteria. Teaching and Learning (Instruction), There is a course specification for all electronic courses at Dar Al Uloom University that includes several topics, the most important of which are the course learning outcomes linked to learning outcomes at the academic program level, and explains their link to teaching strategies and assessment methods. The course specification also provides grades distribution and delivery times for assignments, exams, tools and learning resources. All this information is presented to the student at the beginning of the semester and appears on the home page of the e-course. Instructional materials and technical tools are provided to students with an explanation of how to use them to achieve course learning outcomes. Student Support, Dar Al Uloom University, through its Learning Management System, provides integrated services for the academic, psychological, and social advising while preserving the privacy and confidentiality of student data. It also provides a team to provide technical and administrative support services to all students during their learning time. The university also provides a set of guidelines for using the e-learning system and virtual classrooms, and it periodically holds orientation and training programs for students. Faculty Support, Dar Al Uloom University holds a professional development program annually for faculty members, and they are trained to use the Learning Management System, since March 2020 due to the Corona pandemic, more emphasis has been placed on this type of training in addition to holding seminars and conferences with the participation of specialists in the field of e-learning to raise the level faculty members skills for this type of education, , such as, quality standards for e-learning, pedagogical theories for the e-learning environment, activation of e-learning tools, application of active learning within the e-learning environment, methodologies for developing e-courses. Technical and administrative support teams were also provided to assist the faculty members.
Assessment & Evaluation, all courses at Dar Al Uloom University adhered to the alternatives set by the Ministry of Education to evaluate students' performance in the distance education stage due to the Corona pandemic. The university has formed a higher committee, "the academic committee", to follow up the implementation of measurement and evaluation tools and to ensure their diversity. Training workshops have been held and the provision of guidelines for faculty members and students, especially for evaluation tools.
Despite the successful efforts made by the University of Dar Al Uloom in e-learning (distance learning and blended education) during the Corona pandemic period, the university needs a system to manage the quality of this educational style by adhering to national and international standards that it has already started with, it also needs to define mechanisms for verifying the extent of adherence to these standards through plans and periodic reports as evidence of implementation as the university developing assessment quality sheets based on the suggested criterial in this study in addition to the suggested validation tools, surveying the opinion of the beneficiaries and developing performance indicators for objective judgment of the quality of e-learning and to ensure continuous improvement by studying the results and developing improvement plans. This proposed model helps those in charge of managing and ensuring quality at the University Dar Al Uloom on implementing quality standards for e-learning, standardizing work and raising the level of performance in all courses, and helps them develop improvement plans based on studying the evidence presented in the model, surveying the opinion of the beneficiaries, and measuring the proposed performance indicators.

V. Conclusion and Future Work
This study aimed to present a proposed model for ensuring the quality of e-learning standards and ecourses. The proposed model was based on the V model, which consists of two main sides, the left side for verification processes and the right side for validation process. The left side of the proposed model for this study presents the global and national standards for e-learning that are cited by studies and approved by official authorities such as the National elearning Center in the Kingdom of Saudi Arabia and the Quality Matters Organization (QM). The right side of the proposed model aims to identify the evidence and performance indicators that help the auditors to ensure compliance with the application of these standards mentioned in the left side. The study reviewed the application of these standards at Dar Al Uloom University, and the results indicated that there is a clear commitment to these standards. Accordingly, future work for this study includes the application of all tools mentioned in the proposed model including evidence, performance indicators and surveys in order to identify strengths and priorities for improvement and present the proposed improvement plans to ensure the continuous improvement of the e-learning environment at Dar Al Uloom University.
