      <p>
        Cloud computing is a promising business model[1] for remotely
delivering IT infrastructure, software and platforms as services on a
pay-as-you-use basis[
        <xref ref-type="bibr" rid="ref1">2</xref>
        ]. Cloud computing is considered as the only
cost efficient technology[
        <xref ref-type="bibr" rid="ref2">3</xref>
        ] that has revolutionised and restructured
education through its complete support for online teaching[
        <xref ref-type="bibr" rid="ref3">4</xref>
        ],
learning and research [
        <xref ref-type="bibr" rid="ref1">2</xref>
        ]. Today, cloud computing provides an
effective solution for addressing the scalability issues, financial
crises, insufficient qualified staff, low standards and unstable
policies faced in education[
        <xref ref-type="bibr" rid="ref4">5</xref>
        ].
      </p>
      <p>
        The promising technology used by cloud computing gave
birth to various educative platforms [
        <xref ref-type="bibr" rid="ref5">6</xref>
        ], such as
MOOC[
        <xref ref-type="bibr" rid="ref6">7</xref>
        ], communities of practice[
        <xref ref-type="bibr" rid="ref7">8</xref>
        ], eLearning[
        <xref ref-type="bibr" rid="ref8">9</xref>
        ],
social networking[
        <xref ref-type="bibr" rid="ref9">10</xref>
        ], mobility[
        <xref ref-type="bibr" rid="ref10">11</xref>
        ], informal learning
management[
        <xref ref-type="bibr" rid="ref11">12</xref>
        ], and learning analytics[
        <xref ref-type="bibr" rid="ref12">13</xref>
        ]. These
platforms are now scholarly cited as the prominent
cloudbased applied solution for restructuring education in the
21st century[
        <xref ref-type="bibr" rid="ref13">14</xref>
        ], [
        <xref ref-type="bibr" rid="ref14">15</xref>
        ].
      </p>
      <p>
        A relatively new and the most notable form of these
cloud-based learning and teaching platform, capable of
addressing the scalability and sustainability challenges of
education is MOOC[
        <xref ref-type="bibr" rid="ref1">2</xref>
        ], [
        <xref ref-type="bibr" rid="ref15">16</xref>
        ]–[
        <xref ref-type="bibr" rid="ref17">18</xref>
        ]. MOOC is ―massive,
with theoretically no limit to enrollment; open, allowing
anyone to participate, usually at no cost; online, with
learning activities typically taking place over the web; and
a course, structured around a set of learning goals in a
defined area of study‖[
        <xref ref-type="bibr" rid="ref18">19</xref>
        ]. MOOC is considered as the
―gold rush‖ of higher education[
        <xref ref-type="bibr" rid="ref19">20</xref>
        ] and used by
universities as a prestige marketing tool[
        <xref ref-type="bibr" rid="ref19">20</xref>
        ].
      </p>
      <p>Considering the hike in the cost of schools and low
adoption of cloud services by schools, a research of this
nature will help introduce students to low or free cost
education through MOOC. Likewise, sensitise school
administrators about the use of cloud service models in
schools which in turn reduces the cost of school
administration. Hence, this paper sought to review MOOC
as the major success of cloud computing in the education
sector. The paper begins by reviewing related literature. It
then goes on to establishing the methodology, cloud
computing service models used in education, the state of
the art of MOOC in education, characteristics, types,
benefits and challenges of MOOC, discussion, and
conclusions.</p>

      <title>2. LITERATURE REVIEW</title>
      <p>
        The educational system suffers from small and
unequipped classrooms, insufficient qualified staff, low
standards and unstable policies[
        <xref ref-type="bibr" rid="ref4">5</xref>
        ]. These problems
coupled with the exponential demand for qualitative
education and diversified enrollment of students[
        <xref ref-type="bibr" rid="ref20">21</xref>
        ], [
        <xref ref-type="bibr" rid="ref21">22</xref>
        ]
placed significant pressure on educational institutions[
        <xref ref-type="bibr" rid="ref22">23</xref>
        ].
Prior studies suggested the use of technology for cost
efficient[
        <xref ref-type="bibr" rid="ref22">23</xref>
        ] and quality education delivery[
        <xref ref-type="bibr" rid="ref23">24</xref>
        ]–[
        <xref ref-type="bibr" rid="ref29">30</xref>

thereby addressing the aforementioned challenges.
However, the complexity attached to IT (acquisition,
maintenance, license, virus attacks, delay, etc) has
restrained several

With the emergence of cloud computing, IT services and
infrastructures are now accessed as services rather than acquired as
assets[
        <xref ref-type="bibr" rid="ref31">32</xref>
        ]. For this reason, educational institutions now focus on
research and teaching rather than IT implementation[
        <xref ref-type="bibr" rid="ref20">21</xref>
        ], [
        <xref ref-type="bibr" rid="ref22">23</xref>

        ], [
        <xref ref-type="bibr" rid="ref33">34</xref>
        ]. Consequently, cloud computing leads to delivery of
qualitative education [
        <xref ref-type="bibr" rid="ref22">23</xref>

educational materials[

        <xref ref-type="bibr" rid="ref36">37</xref>
        ]
through the elimination of locally-hosted infrastructures[
        <xref ref-type="bibr" rid="ref37">38</xref>
        ] and
will solve the future scalability and sustainability demand of
education in the digital era[
        <xref ref-type="bibr" rid="ref38">39</xref>
        ]–[
        <xref ref-type="bibr" rid="ref40">41</xref>
        ]. Moreover, today, the
significant spread of education is credited to distance learning
[
        <xref ref-type="bibr" rid="ref41">42</xref>
        ]–[
        <xref ref-type="bibr" rid="ref43">44</xref>
        ] and distance learning is supported by cloud
computing[
        <xref ref-type="bibr" rid="ref44">45</xref>
        ]. In related studies [
        <xref ref-type="bibr" rid="ref4">5</xref>
        ], [
        <xref ref-type="bibr" rid="ref25">26</xref>

        ], [
        <xref ref-type="bibr" rid="ref34">35</xref>
        ] it has been
shown that cloud computing services are a necessity for every
educational institution.

        One of the most scholarly discussed and cited
highscale[
        <xref ref-type="bibr" rid="ref24">25</xref>
        ]distance learning platform is MOOC[
        <xref ref-type="bibr" rid="ref1">2</xref>

        ]–
[
        <xref ref-type="bibr" rid="ref47">48</xref>
        ].Dave Cormier coined the term MOOC in 2008[
        <xref ref-type="bibr" rid="ref48">49</xref>
        ]–[
        <xref ref-type="bibr" rid="ref50">51</xref>
        ].
MOOC efficiently provides out of classroom education[
        <xref ref-type="bibr" rid="ref4">5</xref>
        ], [
        <xref ref-type="bibr" rid="ref51">52</xref>
        ]
and community forums to support interaction among
geographically dispersed participants[
        <xref ref-type="bibr" rid="ref23">24</xref>
        ], [
        <xref ref-type="bibr" rid="ref48">49</xref>
        ], [
        <xref ref-type="bibr" rid="ref52">53</xref>
        ]. It uses the
Internet to bridge the teaching and learning distance, thereby
ubiquitously collaborating participants and providing open access
to educational resources via cloud [
        <xref ref-type="bibr" rid="ref16">17</xref>
        ].
      </p>
      <p>
        In an investigation of MOOC in education, Devgun[
        <xref ref-type="bibr" rid="ref53">54</xref>
        ] revealed
that MOOC platforms are offering free or low-cost education to
students. Another study by [
        <xref ref-type="bibr" rid="ref23">24</xref>
        ] found enhanced and effective
learning performance among MOOC participants. In another major
study [
        <xref ref-type="bibr" rid="ref54">55</xref>
        ] discussed MOOC as efficient value and skills
acquisition initiatives capable of democratising the education
sector. Additionally, [
        <xref ref-type="bibr" rid="ref55">56</xref>
        ] posited that certificate acquired through
MOOC are not as recognised as certificate acquired through
traditional university degrees.
      </p>
      <p>In view of all that has been mentioned so far, one may conclude
that cloud computing and MOOC are disruptive innovation capable
of seamlessly transforming or destroying education. Also, most of
the literature presented thus far has dealt with either cloud
computing in education or state-of-the-art of MOOC. The majority
of the studies are devoid of reviewing cloud computing in
education with an emphasis on MOOC, hence the focus of this
study.</p>

      <p>
        This study primarily adopts software engineering systematic
guidelines for reviews suggested by [
        <xref ref-type="bibr" rid="ref56">57</xref>
        ] and previously adopted in

        ]–[
        <xref ref-type="bibr" rid="ref59">60</xref>
        ]. Additionally, the study employs Creswell (1994)
review guidelines to highlight yet to be resolved issues, hence
challenges of MOOC. Literature for the study was sourced from
conference proceedings (IEEE and ACM), books (Amazon) and
databases (ScienceDirect, Google Scholar, IEEE Xplore, ACM
Digital Library and Springer). Inclusion criteria required studies to
be published in English and contain specific keyword(s) as the title.
Strictly, these keywords include ―cloud computing‖ AND
―MOOC‖ AND ―education‖. On a more general search, the
keywords were searched as ―cloud computing‖ OR ―MOOC‖ OR
―education‖. Using this search criterion, various related and
unrelated literature was found which was systematically
filtered based on the inclusion criteria. At the end, 149
works were found to be related and relevant to the study.
For the purpose of analysis, abstract and main findings of
the studies were systematically extracted and analysed
based on Glaser (1965)constant-comparative qualitative
method of data analysis, previously used by[

        Cloud computing is an emergent technology[

        ], publishing and networking[
        <xref ref-type="bibr" rid="ref22">23</xref>
        ]
educational resources. Basically, cloud computing
encompasses three (3) service models: Infrastructure as a
Service (IaaS), Platform as a Service (PaaS) and Software
as a Service (SaaS) [
        <xref ref-type="bibr" rid="ref63">64</xref>
        ]–[
        <xref ref-type="bibr" rid="ref65">66</xref>
        ].These service models
respectively handle the storage, development platforms
and application requirements of every educational
institution [
        <xref ref-type="bibr" rid="ref64">65</xref>
        ].
      </p>
      <p>
        IaaS handles the on-demand processing, storage,
networking and basic computing requirement of students,
lecturers and researchers[
        <xref ref-type="bibr" rid="ref4">5</xref>
        ], [
        <xref ref-type="bibr" rid="ref21">22</xref>
        ], [
        <xref ref-type="bibr" rid="ref24">25</xref>
        ], [
        <xref ref-type="bibr" rid="ref29">30</xref>
        ]. Examples of
IaaS are Google Compute Engine, IBM cloud academy,
Amazon Web Services (AWS), Microsoft Azure Virtual
Machines and Google Cloud Storage. Similarly, PaaS is
built upon IaaS[
        <xref ref-type="bibr" rid="ref24">25</xref>
        ] and it provides the frameworks for
programming and deployment of applications[
        <xref ref-type="bibr" rid="ref29">30</xref>
        ].
Examples of PaaS are Google App Engine, Heroku and
Force.com. accordingly, SaaS has been a popular model
for education since the mid-1990s[
        <xref ref-type="bibr" rid="ref4">5</xref>
        ]. SaaS primarily uses
web client and network to remotely provide applications,
multimedia and web services to users[
        <xref ref-type="bibr" rid="ref5">6</xref>
        ]. In essence, it
leverages the burden of locally installing applications and
license acquisition from the user[
        <xref ref-type="bibr" rid="ref38">39</xref>
        ], [
        <xref ref-type="bibr" rid="ref65">66</xref>
        ] to a Cloud
Service Provider (CSP). Examples of SaaS includes
Microsoft Office 365, Google Apps for Education, etc.
Prior studies[

        ],
[
        <xref ref-type="bibr" rid="ref65">66</xref>
        ] have shown that IaaS and SaaS are the top enterprise
services in the education industry. Educational institutions
uses IaaS to provide storage and processing of educational
contents[
        <xref ref-type="bibr" rid="ref4">5</xref>

        ], [
        <xref ref-type="bibr" rid="ref37">38</xref>
        ]. Additionally, SaaS addresses
software needs to create contents, provide virtual worlds,
collaboration; simulations, resource sharing, video
streaming, etc [
        <xref ref-type="bibr" rid="ref14">15</xref>

        ].
      </p>

        Nonetheless, around the benefits of cloud computing lies
various issues of performance [

MOOC[

        ], [
        <xref ref-type="bibr" rid="ref67">68</xref>
        ]. New York Times declared 2012 as
the year of MOOC [

        ], [
        <xref ref-type="bibr" rid="ref69">70</xref>
        ] due to the emergence and
contribution of several MOOC platforms providing
effective free or low-cost education for all [
        <xref ref-type="bibr" rid="ref70">71</xref>
        ]. MOOC
perfectly depicts a technology enabled and open

        Openness and collaboration are important developments in the
academia. This brings forth the opportunity for everyone to engage
in university level learning[
        <xref ref-type="bibr" rid="ref67">68</xref>
        ]. The openness, massiveness and
limitless scope make MOOC different from other online
education[

[

and debates about the future of higher education[
        <xref ref-type="bibr" rid="ref71">72</xref>
        ]. Elite
universities and practitioners in the academia are the leading
advocates of MOOC [
        <xref ref-type="bibr" rid="ref50">51</xref>
        ]. They consider MOOC as the future of
education [

        ], [
        <xref ref-type="bibr" rid="ref81">82</xref>
        ], [107], [108]. They also outlined that,
MOOC emerged due to the current globalfinancial crisis,
educational budget cuts and the need for the education sector to
utilise technology for research, learning,teaching, content delivery,
access and collaboration[

      <title>5.3 Types of MOOC</title>
      <p>
        What determines a MOOC is the mode in which it is delivered[
        <xref ref-type="bibr" rid="ref99">93</xref>
        ].
There are two (2) basic types of MOOCs vizcMOOC and
xMOOC[
        <xref ref-type="bibr" rid="ref50">51</xref>
        ], [
        <xref ref-type="bibr" rid="ref102">96</xref>
        ], [
        <xref ref-type="bibr" rid="ref107">111</xref>
        ]. However, in recent times, other types
have evolved and emerged. This includes: pMOOC (project based
MOOC), LOOC (Local Open Online Courses)[
        <xref ref-type="bibr" rid="ref99">93</xref>
        ], SPOC (Small
Private Online Courses)[
        <xref ref-type="bibr" rid="ref113">117</xref>
        ]. Others includes Wrapped
MOOC[118], White label MOOC, Mini MOOC, DOCC
(Distributed Open Collaborative Course)[
        <xref ref-type="bibr" rid="ref115">119</xref>
        ] and SMOC
(Synchronous Massive Online Course) [
        <xref ref-type="bibr" rid="ref108">112</xref>
        ].
      </p>
      <p>
        In cMOOC, the c denotes connectivism or connectivist[
        <xref ref-type="bibr" rid="ref108">112</xref>
        ], hence
they are based on connectivist[
        <xref ref-type="bibr" rid="ref46">47</xref>
        ], [
        <xref ref-type="bibr" rid="ref106">100</xref>
        ] and informal learning
theory[
        <xref ref-type="bibr" rid="ref50">51</xref>
        ]. Connectivism is best explained by peer and social
learning models. They promote knowledge seeking, sharing[
        <xref ref-type="bibr" rid="ref15">16</xref>
        ]
and learners autonomy[
        <xref ref-type="bibr" rid="ref116">120</xref>
        ], thereby enhancing interaction among
participants. Several controversies still surround the acceptance of
connectivism as a philosophy of learning in this digital age[
        <xref ref-type="bibr" rid="ref117">121</xref>
        ],
[
        <xref ref-type="bibr" rid="ref118">122</xref>
        ].
cMOOC are structured to include video presentations, tests and
short quizzes[
        <xref ref-type="bibr" rid="ref96">91</xref>
        ]decentralised over a network[
        <xref ref-type="bibr" rid="ref48">49</xref>
        ]. In cMOOC, the
instructor provides the course outline and students define the
course materials and course contents. Thus the participants of
cMOOCs are active, while the instructors are seen more as
moderators rather than tutors[
        <xref ref-type="bibr" rid="ref106">100</xref>
        ]. cMOOC uses Open Education
Resources [
        <xref ref-type="bibr" rid="ref99">93</xref>
        ], hence making its learning resources open rather
than proprietary. Examples of cMOOC include Personal Learning
Environments, Connectivism and Connective Knowledge,
MobiMOOC, and EduMOOC[
        <xref ref-type="bibr" rid="ref106">100</xref>
        ]. Currently, edX uses the
cMOOC pedagogy for content delivery.
      </p>
      <p>
        Recently, Havard University instigated the term xMOOC to depict
courses offered offline [
        <xref ref-type="bibr" rid="ref48">49</xref>
        ] with online discussion forums. The x in
xMOOC denotes exponential or extension, thereby focusing on
massive participation [
        <xref ref-type="bibr" rid="ref108">112</xref>
        ], through the use of proprietary learning
resources [
        <xref ref-type="bibr" rid="ref99">93</xref>
        ]. xMOOC perfectly exemplifies the digital version of
a traditional education course.
      </p>
      <p>
        An xMOOC is structured to include at least one instructor, an
instructor predefined course content and a participant self-paced
syllabus [
        <xref ref-type="bibr" rid="ref47">48</xref>
        ], [
        <xref ref-type="bibr" rid="ref80">81</xref>
        ], [123]–[127]. Therefore, unlike cMOOC,
xMOOC participants are considered as passive learners. However,
xMOOC is more engaging than cMOOC. It incorporates
gamerelated elements and online simulation to keep learners focused and
motivated [125]. Additionally, xMOOC ensures quality delivery
through the integration of quality assurance protocols[
        <xref ref-type="bibr" rid="ref99">93</xref>
        ].
The duration of xMOOC video lectures ranges from 3 to 15
minutes and are structured in terms of weeks. Each week contains
video lectures, reading materials, online discussion, quizzes and
assignments[
        <xref ref-type="bibr" rid="ref121">126</xref>
        ]. Currently, Coursera and Udacity are
examples of third party vendors delivering xMOOC
contents.
      </p>
      <p>
        Today xMOOC is termed the modern MOOC and forms the
widely known MOOC [
        <xref ref-type="bibr" rid="ref14">15</xref>
        ]. It follows the broadcast model of
knowledge dissemination[128]. However, [
        <xref ref-type="bibr" rid="ref106">100</xref>
        ] reported that
no conclusion has been made regarding which is better than
the other between x and c MOOC.

      <title>5.4 Benefits of MOOC in Education</title>
      <p>
        Prior studies [
        <xref ref-type="bibr" rid="ref122">129</xref>
        ], [130] have raised alarm about the
continuous increase in the cost of post secondary
education. In an investigation, [
        <xref ref-type="bibr" rid="ref105">99</xref>
        ] found that MOOC has
the potential to lower the cost of earning a degree. Today,
MOOCs completely addresses the exponential increase in
the cost of acquiring traditional education[131], [132].
This is achieved through the delivery ofcost efficient,
flexible and focused online educational practicesby
MOOC providers [133].
      </p>
      <p>
        In addition, by removing the distance barrier, MOOC
efficiently and cheaply extends the reach of education to
every part of the world. Students in underdeveloped and
developing countries now take classes directly from elite
universities at a less or no cost [134]. This extension in
turn increases the prestige of the hosting universities
thereby improving educational outcomes and
revenues[
        <xref ref-type="bibr" rid="ref108">112</xref>
        ]. Hu [
        <xref ref-type="bibr" rid="ref99">93</xref>
        ] highlighted the benefits of MOOC
in developing countries. The study stated that, the offline
learning capability of MOOC enhances the adoption and
addresses the network inadequacy in developing
countries.
      </p>
      <p>
        Furthermore, MOOC provides personified education i.e.
every student a class and every class its student. This
permits students to have control over what they learn,
when they learn and how they learn. Thus promoting
crowd sourcing which enhances collaboration and social
networking among students [
        <xref ref-type="bibr" rid="ref68">69</xref>
        ]. In essence, MOOC
promotes high level of interaction among students without
instructor mediation and moderation which enables
students to independently develop their own ideas, skills,
knowledge, learning network, enhance self expression
[
        <xref ref-type="bibr" rid="ref116">120</xref>
        ], [135], [136], deep learning and abstract
conceptualization[137], [
        <xref ref-type="bibr" rid="ref123">138</xref>
        ].
      </p>
      <p>
        The course content of MOOCs are mostly facilitated by
highly qualified professors and scholars in the academia
[
        <xref ref-type="bibr" rid="ref87">88</xref>
        ]. Therefore, MOOC imparts qualitative, lifelong cost
effective skills and experiences [
        <xref ref-type="bibr" rid="ref82">83</xref>
        ], [
        <xref ref-type="bibr" rid="ref100">94</xref>
        ], thereby
enhancing professional credentials[
        <xref ref-type="bibr" rid="ref80">81</xref>
        ], [
        <xref ref-type="bibr" rid="ref124">139</xref>
        ] and
providing job advancement [
        <xref ref-type="bibr" rid="ref54">55</xref>
        ]. Some MOOC providers
such as Udacity recommend Nanodegree course
participants for job placement. Additionally, several
MOOC providers issues certificate that can be showcased
on participant LinkedIn profile.
      </p>
      <p>
        Similarly, MOOC appears to provide an economic
solution to universities and also a medium for universities
tocompete with their peers[
        <xref ref-type="bibr" rid="ref4">5</xref>
        ], thus increasing the number
of universities engaged and offering qualitative MOOCs.
This enhances the prestige of the university, global
awareness about the university, and increases the rate of student
enrollment in the university [
        <xref ref-type="bibr" rid="ref72">73</xref>
        ]. A prior study [
        <xref ref-type="bibr" rid="ref99">93</xref>
        ] show that
MOOC addresses the need for more infrastructural expansions
among existing universities. likewise, [
        <xref ref-type="bibr" rid="ref112">116</xref>
        ] concluded that MOOC
addresses the need for more universities.
      </p>
      <p>
        Moreover, MOOC goes beyond enhancing students learning
experience to enhancing managers and employees skills by
providing in-service training courses, thereby upgrading theirskills
base and curriculum vitae[
        <xref ref-type="bibr" rid="ref99">93</xref>
        ].Therefore, with MOOC, the
campusbased time requirement for working professions are
eliminated[134].
      </p>
      <p>
        Among other benefits, MOOC provides researchers with
wellstructured data about learning patterns across various MOOCs[
        <xref ref-type="bibr" rid="ref54">55</xref>
        ],
eases the teaching and learning of several educational areas and
topics [
        <xref ref-type="bibr" rid="ref99">93</xref>
        ], and finally fosters collaborative research among
communities.

        <xref ref-type="bibr" rid="ref2">3</xref>
        ][
        <xref ref-type="bibr" rid="ref70">71</xref>
        ].
      </p>
      <p>
        The most discussed challenge of MOOC is high dropout [
        <xref ref-type="bibr" rid="ref125">140</xref>
        ],
hence low completion rate. Prior studies[
        <xref ref-type="bibr" rid="ref54">55</xref>
        ], [128], [141], [
        <xref ref-type="bibr" rid="ref126">142</xref>
        ]
found that less than 10% of participants completes a MOOC. This
brought about MOOC criticism due to 90% dropout rate of
enrollees, in essence, 90% of people who signed up for a MOOC
do not complete them [
        <xref ref-type="bibr" rid="ref50">51</xref>
        ]. Scholarly investigation identified
insufficient or lack of incentive, lack of life teacher support and
difficulty as the major causes of high dropout rate in MOOC[
        <xref ref-type="bibr" rid="ref47">48</xref>
        ],
[
        <xref ref-type="bibr" rid="ref80">81</xref>
        ], [
        <xref ref-type="bibr" rid="ref101">95</xref>
        ], [143]. Additionally, the lack of prior knowledge may
contribute to the dropout rate[
        <xref ref-type="bibr" rid="ref80">81</xref>
        ].
      </p>
      <p>
        Cheating is one of the major challenges of MOOC [
        <xref ref-type="bibr" rid="ref127">144</xref>
        ]. Virtual
student assessment and unverifiable identity of participant
contributed to the emergence of cheating among MOOC
participants [
        <xref ref-type="bibr" rid="ref48">49</xref>
        ], [
        <xref ref-type="bibr" rid="ref119">124</xref>
        ]. On this note, [134] stated that MOOC
certificates may not be considered by employers due to the
unverifiable quality of students skills and experience. To efficiently
evaluate students, new assessment methods are required [145],
[146]. These methods must efficiently collect, classify and
understand in-classroom teaching and learning[147]. On this note,
there is an ongoing experiment on the use of computers to grade
essays for ensuring effective student assessments [148]. However,
[149] reported that this software are unreliable.
      </p>
      <p>
        Another challenge is the use of peer assessment by some MOOC
provider. The good side of peer assessment lies in its quality
feedback. Feedback depicts instructor‘s comment or evaluation of
learner‘s context [
        <xref ref-type="bibr" rid="ref128">150</xref>
        ]–[
        <xref ref-type="bibr" rid="ref129">153</xref>
        ]. However the case of MOOC using
peer assessment for performance evaluation to ensure feedback
contradicts scholarly views about feedback. Additionally, peer
review perfectly exemplifies a novice guiding a novice, thereby
resulting in shallow learning. In essence, peer evaluation does not
efficiently measure and assess learning achievement [
        <xref ref-type="bibr" rid="ref130">154</xref>
        ]–[
        <xref ref-type="bibr" rid="ref134">158</xref>
        ].
On the contrary about peer evaluation, [
        <xref ref-type="bibr" rid="ref135">159</xref>
        ] opined that peer
evaluation encourages and motivate students to learn and
collaborate.
      </p>
      <p>
        In like manner, there is a limitation in the number of fields that can
be taught through MOOC. For instance, medicine requires
face-toface instructor mediated practice and interaction. Such
courses may not appear in the world of MOOC in the
nearest future [134] and eventually if they do, the
reputation of the participants needs serious verification.
Participation dissatisfaction is another challenge of
MOOC. There is influenced by technical know-how
requirement of MOOC [
        <xref ref-type="bibr" rid="ref54">55</xref>
        ], [107], [128], [
        <xref ref-type="bibr" rid="ref136">160</xref>
        ], [
        <xref ref-type="bibr" rid="ref137">161</xref>
        ],
possible loss of focus in discussion forum and
out-ofscope postings by participants[
        <xref ref-type="bibr" rid="ref79">80</xref>
        ]. Additionally, it is
influenced by MOOC demands for commitment both in
time and money [
        <xref ref-type="bibr" rid="ref47">48</xref>
        ]. Therefore, MOOC designers need
real-time systems for detecting dissatisfied
participants[
        <xref ref-type="bibr" rid="ref83">84</xref>
        ], moderating discussion forum and
reducing the complexity of participating in a MOOC.
      </p>
      <p>
        Though, MOOC is used by universities as a marketing
tool, the provision of low-quality courses through MOOC
may significantly damage the reputation and recognition
of universities rather than market it [
        <xref ref-type="bibr" rid="ref50">51</xref>
        ].
      </p>
      <p>
        Accordingly, MOOC professors and tutors consider the
preparation of course material as very hectic and time
demanding[
        <xref ref-type="bibr" rid="ref105">99</xref>
        ]. Averagely, the time required to prepare
an adequate MOOC is 100 hours.
      </p>
      <p>
        Among other challenges, [134] considered acceptability,
student experience and quality as the major problems of
MOOC. Consequently, there are possible loss of cultural
values and norms among MOOC participants[
        <xref ref-type="bibr" rid="ref67">68</xref>
        ][162].

      <title>6. DISCUSSION AND CONCLUSIONS</title>
      <p>This study has analysed the most relevant contributions of
cloud computing to MOOC and MOOC to education. The
study found storage and software as the most used cloud
services in education. MOOC is relatively new and
considered as a disruptive innovation capable of
transforming the educational sector. Literature has shown
that previous disruptive innovations came with various
challenges. Therefore, the disruptiveness and
innovativeness of MOOC must also come with various
challenges. These challenges will form the basis for its
perfection and stability. Despite these challenges, it is
important for universities and educational institutions to
value MOOC and cloud computing due to their significant
roles in the education sector.</p>
      <p>Various challenges have been identified in the study.
However, MOOC dropout rate appear to be the most
discussed challenge. It should be noted that the dropout
rates across different MOOC varies. Therefore, the target
audience and purpose of the MOOC determines the
enrollment and dropout rate. For instance, a computer
science based course may draw more attention and
completion rate than a social science based course due to
the inclined use of the computer by the former when
compared to the later.</p>
      <p>
        Accordingly, with respect to the issue of certificate
recognition, it was found that most students engage in
MOOC to support lifelong learning, for fun, continence
and also for experience[
        <xref ref-type="bibr" rid="ref80">81</xref>
        ]. This indicates that the quest
for certification is not the major motivation of various MOOC
participants.
      </p>
      <p>One MOOC platform appearing to solve the participant verification
is Coursera through its Signature Track. This Signature Track
authenticates the identity of the participant by typing and matching
a signature phrase. Accordingly, edX offers the Verified Certificate
of Achievement service where participants are monitored and
supervised through webcam to ensure their performance.
The findings from this study imply that the solvable challenges of
MOOC will sum up with its benefits in the long run. Therefore, if
the administrators of education do not accept MOOC as an
innovation that has come to stay, MOOC may do to education what
cloud computing did to business and the lagers will be the one to
lose.</p>
      <p>In view of this, this study suggests the establishment of MOOC test
centres. This test centres will help in the elimination of cheats and
impersonation in MOOC. This may also lead to pre and post
assessment of participant skills, hence resulting into quantifying
the ideal impact of MOOC on participant and enhancing certificate
recognition. Additionally, the study recommends the enhancement
of MOOC framework, the integration of MOOC in the national
curriculum and recognition of MOOC certificates in all nationals.
As a future research, interoperability of MOOC providers is an
important issue worthy of scholarly consideration. This will
enhance service level interoperability among providers thereby
eliminating duplication of knowledge.</p>
