        <p>The use of adaptive massive open online courses (MOOCs) in the educational process of students contributes to the expansion of ways to implement personalized learning. The development of new approaches and intellectual methods for this area is a priority. Based on the developed approaches, it is possible to build individual educational paths in MOOCs. The analysis showed that the development of new intellectual methods for providing complex personalization in the SMART educational cloud environment requires further research and scientific justification. The development of this direction will ensure the implementation of the most important didactic principles: individualization, differentiation and adaptability. In this paper we summarize the approaches and methods used to provide personalization in the MOOC. In our research model of the adaptive MOOC architecture is presented. It includes describing of the following main components: «Database Student», «Database Course», «Database Learning Process», «MOOC Intelligent System», «Personal Learning Path». The interconnection of the processes of these components is based on Big Data processing and analysis, using the methods Data Analysis, Learning Analytics, Education Data Mining.</p>

        In recent years, a number of changes have taken place in the educational environment,
which have had a serious impact on the methodology of mastering and the practice of
teaching the academic disciplines at the university. Nowadays the concepts of the
personal educational environment of students and individual educational path are
actively developing. Introduction in the educational process of massive open online
courses has allowed expanding the boundaries for learning by students of different
disciplines or separate modules of disciplines [
        <xref ref-type="bibr" rid="ref12 ref3">3,12</xref>
        ]. Students have an advantage to
choose the order of the study material according to their interests and needs. But, one
of the completely unsolved problems, despite the opportunities that have been opened,
remains the task of optimal planning, construction and correction of individual
educational path. Modern learning management systems contain a considerable amount of
information, allow forming the profile of the student, based on his preferences,
academic performance and other significant criteria. Because online courses involve
massive work with students, the traditional planning personalized training routes to
become very difficult for tutors accompanying rates. In our research we proposed the
solution for solve this problem. We developed approach which include automated
accompaniment of personalized work with listeners in the SMART educational cloud
environment, based on the principles of intellectual self-organization.

      <title>Problem overview</title>
      <p>An important condition for the adoption of effective solutions in the field of e-learning
is an analysis of data from the participants of the educational process at various stages.
Nowadays, the volume of data circulating in the educational environment, providing
work with online courses, grows exponentially. This is facilitated by the rapidly
growing demand for open education. In this way, it is necessary to develop new approaches
to the creation of SMART educational cloud environment. The basic component of
such an environment is adaptive massive open online courses. We offer an approach
based on the methods of Learning analytics and the methods of Education Data
Mining.</p>
      <p>Modern online learning systems are aimed at working with Big Data, which, first of
all, is conditioned by the basic principles that are fundamental for an innovative
educational environment. In our research we defined as the main following principles:
spontaneity of learning (gaining knowledge regardless of control and scheduling),
adaptability (use of data on previous experience of teaching each learning to plan the
learning process and track educational progress), the «invisibility» of the evaluation
(ensuring automatic collection of data on the behavior of the listener in the learning
process).</p>
      <p>The main problem with the existing systems of online learning management is the
lack of integrated support for all listed elements. Basically, this is due to the high
resource intensity and computational complexity of the analyzed parameters. For the
same reason, the process of constructing individual educational trajectories is
complicated. Accumulated data is not analyzed in real time. So, for example, each potential
learner has his own learning goals, interests. Also each learner needs his own set of
content components and ways of activities in a particular situation. Therefore, it is
necessary to use such e-learning opportunities that will ensure the formation of
socially-demanded competences in the most differentiated, fast, high-quality and effective
manner. The solution to the problem can be the use of heuristic methods built on
methods of machine learning. Thus, the task of forming a profile of the interests of the
listener of an online course can be solved by using teaching methods with a teacher,
without a teacher, with partial teacher involvement, with reinforcement or multi-level
training. At the same time, existing innovative data processing technologies based on
methods of data mining and neural networks. But such approaches for correct work
require the use of preliminary expert evaluation on reliable samples for further
training and verification. In order to effectively configure such a system, the stored, but
previously unused data becomes particularly important, which in turn also introduces
additional overhead costs for the analysis and verification of this information.

      <title>Discussion</title>
      <p>
        Let's generalize the various approaches, algorithms and methods that provide
personalization of training in MOOC, proposed by different researchers. For example, in [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]
the implementation of a system of personal recommendations to listeners of MOOC
on the study of additional thematic video lectures and educational resources based on
the behavior of participants of the course, their interests and preferences is presented.
This system is implemented on the basis of the results of processing large sets of data
obtained when watching video lectures by students and their active participation in
forums.
      </p>
      <p>
        Qiang Tang [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ] proposed a different approach to providing personalization of
training in the MOOC. The listener, who first registered on the MOOC platform, passes a
test to determine the learning style and learning strategy. Based on the results, the
user’s personal dynamic Bayesian learning network. Using the information from the
Bayesian learning network, the MOOCs platforms gets the learner’s personalized
features and pushes adaptive courses and learning companion to create learning
communities.
      </p>
      <p>
        A team of researchers from Armenia [
        <xref ref-type="bibr" rid="ref5">5</xref>
        ] outlined the approach to personalization of
learning, based on «teaching scenarios» (sequence of teaching units), which
constructed during the process of learning. These scenarios are being constructed via the
quality and quantity characteristics of the teaching units and user’s knowledge. As a result,
a group of researchers using genetic algorithms solve such important tasks in
elearning systems as creating adaptive learning scenarios and constructing a
corresponding course map reflecting the progress of each particular learner.
      </p>
      <p>
        A group of scientists consisting of Xiao-hong Tan, Rui-min Shen and Yan Wang
suggest using genetic algorithms to build online courses that take into account not
only the level of complexity of the material and the time taken for its mastering, but
also the changing results of training of individual students in time of the educational
process [
        <xref ref-type="bibr" rid="ref4">4</xref>
        ].
      </p>
      <p>Another method of personalization, according to a group of researchers from
Greece and Spain, is to use the learning / prediction algorithms, which are the basis of
the system of personal recommendations. Such a system can prepare intelligent
recommend actions to the learner based on the actions of previous participants in the
course, and make a dynamic correction of the content of the course based on the
profile of the trainee's profile, its interests and needs.</p>
      <p>
        Another approach to ensure the personalization of learning is based on the
technique of evolution through computerized adaptive testing. Then the genetic algorithm
and case-based reasoning are employed to construct an optimal learning path for each
learner [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ].
      </p>
      <p>
        A team of researchers from China [
        <xref ref-type="bibr" rid="ref7">7</xref>
        ] proposes a personalized system of
recommendations in the MOOC, based on Dynamic Bayesian Network.
      </p>
      <p>
        In the next paper [
        <xref ref-type="bibr" rid="ref8">8</xref>
        ], led by Jill-Jênn Vie, it is proposed to use adaptive testing in
MOOC, in which the test tasks are formed by predicting the student's academic
performance. Such an approach, according to the authors, will prevent the students from
dropping out of the course, and also provide feedback to the test subject at the end of
the test, indicating which knowledge components need further study.

      <title>The architecture of adaptive massive open online courses</title>
      <p>SMART educational cloud environment, which is personalized, is characterized by
complexity, high dynamism, and huge data flows. Wherein:</p>
      <p>1. When we use of intelligent information technologies in the construction of
adaptive MOOC goals and the pace of training, electronic educational content, as well as
methods and means of teaching can vary depending on the interests, needs,
characteristics of individual students, the degree of their readiness for learning, the results of
tracking progress in the learning material. For example, recommendations can be
offered for mastering individual variable modules of discipline or related online courses
that expand and deepen knowledge in a specific subject area.</p>
      <p>2. The adaptive learning subsystem in MOOC offers everyone an optimal
individual space-time educational route and can organize groups of listeners who are similar in
terms of educational preferences and opportunities, for example, for the joint
evaluation of completed assignments.</p>
      <p>We developed an adaptive MOOC architecture (see Fig. 1), each components of
this structures we describe in more detail.</p>
      <p>Database Student-a set of different characteristics of students (variable and constant
data), which can be used in the process of the adaptive MOOC. Such characteristics
include such Big Data as learning goals, interests in the subject area, the results of the
survey, diagnostic testing, personal profile data (age, gender), psychological profile
data (learning style, perception and memorization) and others. From the data contained
will be selected those that distinguish a particular student or most accurately
characterize his personality.</p>
      <p>Database Course-information about courses and sets of their various characteristics
that can be used in the process of creating an adaptive MOOC. Those characteristics
that are most suitable for the needs and capabilities of a particular student will be
selected from the existing ones.</p>
      <p>Database Learning Process-a set of different characteristics describing the learning
process (progress of students) based on a specific MOOC. Those who most accurately
describe or characterize a personal way of realization of personal potential of the
concrete trained will be chosen from the keeping characteristics. The meaning of these
characteristics is constantly changing in the learning process based on MOOC. Such
characteristics include such as points for each educational object being evaluated (for
example, 50-70% - low, 71-89% - medium, 90-100% - high); the level of complexity
of the material on the student feedback (simple, normal, complex); time spent on
tasks; other.
MOOC Intelligent system is a module of hybrid intelligent system, responsible for the
adaptability of the mooc to the needs, preferences and capabilities of a particular
student. In this module, more than one method of human intellectual activity simulation
is used to solve the mooc adaptability problem, for example, fuzzy logic, genetic
algorithms, artificial neural networks, simulation statistical models and others.
Neurofuzzy models allow, on the one hand, to bring the ability to learn and the
computational power of neural networks into systems with fuzzy logic, and on the other hand – to
strengthen the intellectual capabilities of neural networks inherent in the "human" way
of thinking fuzzy rules of decision-making. optimization of the educational process by
providing students with educational material in the most preferred form.
Personal learning path-a script that allows for each student to form an individual
learning path for the development of a particular MOOC, which is later corrected in real
time. For the purpose of correction of an individual trajectory of training the methods
of data mining based on personal features and preferences of the trained are used.
The described architecture is a General representation of the implementation of
adaptive MOOC and requires further detailed description of the functioning of all its
components.

      <title>Conclusion</title>
      <p>The article attempts to design a multifaceted, holistic, self-organizing cloud
environment based on MOOCs, which creates the conditions for maximizing the personal
potential of each learner by simultaneously creating the following components:
adaptive content and training program, an optimal individual educational route, an
intelligent selection system and course recommendations for interested students of the
educational platform taking into account their personal interests, possible needs, personal
characteristics for organizing collaborative work in the implementation of joint
projects and other effective educational network interaction.</p>
      <p>Thus, for today the task of searching for and creating effective methods for
intellectual processing of large data sets for the complex personalization of the cloud
educational environment remains completely unresolved and is in the stage of actualization.</p>
