                       Abstract. Personalized learning is an up-to-date trend of formal and informal
                       education development. Its main peculiarity is the maximum consideration of
                       the person's educational needs. Nowadays, personalized learning involves de-
                       velopment of student model based on personal characteristics; customized
                       learning content, as well as intellectual information and communication tech-
                       nologies. These approach is considered as adaptive learning. Research results in
                       the field of personalized and adaptive learning are presented in numerous publi-
                       cations. Thus, it was decided to perform the search in Scopus and Web of Sci-
                       ence Core Collection, as well as the electronic libraries of the Institute of Elec-
                       trical and Electronics Engineers and Association for Computing Machinery.
                       The study consisted of two stages: 1) search by a set of key phrases; 2) search
                       by a custom search query. The results of the analysis of the generated sample by
                       years of publication, countries of origin of authors, number of citations are pre-
                       sented in tables and diagrams. Moreover, the review of some significant publi-
                       cations is given, and main areas of further studies are detected such as, the ex-
                       amining of teachers' experience in the field of use adaptive learning systems.

                       Keywords: personalized learning, adaptive learning, review.


               1       Introduction

               Increasing attention to a person-centered learning approach, widespread use of infor-
               mation and communication technologies in formal and non-formal education become
               a factor of the intensive research in the field of learning individualization and personi-
               fication. The scientific results are reflected in numerous publications. In particular,
               methodological approaches and aspects of using information and communication
               technologies for personalized learning are presented in [1; 2; 3; 4; 5; 6].

   As Turčáni and Balogh mention, personalized learning recognizes learners' diversi-
ty, cognitive and physical differences and the overall individuality. It includes various
learning styles and approaches: from focused on the educational content to focused on
supporting the learners by communication, discussion, cooperation [7, p. 47-48].
   So, it is important to study the current state of research of the problem by review-
ing literature sources. It is a common method of analysis, so there are a lot of articles
presenting the reviews of publications on various aspects of personalized and adaptive
learning.
   Akbulut and Cardak [8] made a content analysis of studies describing adaptive ed-
ucational hypermedia (AEH) with a focus on learning styles. They searched publica-
tions from 2000 to 2011 in several electronic databases, namely Ulrich’s Periodicals
Directory, ISI Web of Knowledge, EBSCOhost Web, SpringerLink, ERIC, Google
Scholar and others. For research purpose different key words and phrases were used,
eg. "adaptive/adaptable e-learning”, "adaptation", "personalized e-learning", "learning
styles". Authors selected 70 papers of such types as peer-reviewed articles, full-text
proceedings of international conferences, symposia and workshops, and dissertations
in English. These publications were classified under several categories, namely Publi-
cation type, Main focus, Purpose, Study nature, Variables used for adaptivity, Learn-
ing style model, Student modeling, Tool for modeling, Tools for dynamic modeling,
Research settings, Participants, Type of empirical studies, Data collection tools. As a
result, authors identified some expectations of AEH using in education.
   We examined some other papers dedicated to literature review on personalized
learning and adaptive learning systems. A systematic literature reviews were conduct-
ed to study individual differences accommodating in adaptive learning systems
(Nakic, Granic, and Glavinic [9]); using competence-based recommender systems
(Yago, Clemente, and Rodriguez [10]); personalized electronic learning models as a
combination of learning theories, techniques and tools (Jando et al. [11]); characteris-
tics, applications, and evaluation methods of intelligent tutoring systems
(Mousavinasab et al. [12]); personal traits in adaptive learning environment and
learners' models (Normadhi et al. [13]); challenges in the online component of blend-
ed learning (Rasheed, Kamsin, and Abdullah [14]).
   The main motivation which encourages us to conduct this study is necessity to de-
fine methodological foundations and appropriate means of development of personal-
ized adaptive learning system for professional training at universities, within the re-
search on request of the Ministry of Education and Science of Ukraine, registration
number 0120U101970. To achieve this goal needs to select pool of theoretical and
applied papers.
   Furthermore, there are two research questions in our study. First, "are issues of
personalized and adaptive ICT-enhanced learning up-to-date?". Second, "what are the
ICT-means for personalization of learning?". This study was conducted through a
review relating to personalized and adaptive ICT-enhanced learning of papers pub-
lished from 2010 to 2019.
2      Methodology

In the course of our study, we relied on the methodological foundations of the litera-
ture review as a research method outlined in [15; 16; 17], as well as materials of sci-
entific publications Akbulut and Cardak [8], Nakic, Granic, and Glavinic [9], Yago,
Clemente, and Rodriguez [10], Jando, Meyliana, Hidayanto, Prabowo, Warnars, and
Sasmoko [11], Afini Normadhi, Shuib, Md Nasir, Bimba, Idris, and Balakrishnan
[13], Rasheed, Kamsin, and Abdullah [14].
   We analyzed the scientific publications in the abstract and citation databases Sco-
pus (https://www.scopus.com) and the Web of Science Core Collection
(www.webofknowledge.com), as well as the libraries of the Institute of Electrical and
Electronics Engineers (IEEE, https://ieeexplore.ieee.org) and the Association for
Computing Machinery (ACM, https://dl.acm.org/). These electronic resources were
selected since they contain international scientific sources of high impact-factor. In
order to select the most up-to-date and thorough research, it was decided to introduce
additional restrictions, namely: articles in periodicals and proceedings of scientific
conferences, as well as books and parts of books published in 2010-2019.
   Web services of Scopus and Web of Science Core Collection abstract and citation
databases provide a strong search functionality. In particular, we used filtration by
subject area / category. Since our research was mainly related to the educational pro-
cess, the subject area "Social Sciences" was selected for search in Scopus, and the
category "Education educational research" in Web of Science Core Collection. The
search was performed under the Title, Abstract and Keyword fields.
   On the first stage, in order to determine the general level of scientific interest in the
field of adaptive and personalized learning, we conducted a search in three categories,
which can be defined as: "personalization of learning", "adaptation of learning",
"information systems for learning". In the process of keyword selection, we relied on
works [9; 13; 18]. Three key phrases were selected for each area, namely:

• "personalization of learning": "personalized learning", "individual learning", "di-
  rect instruction";
• "adaptation of learning": "personalized e-learning", "adaptive learning", "intelli-
  gent tutoring";
• "information systems for learning": "personalized learning environment", "adaptive
  learning system", "intelligent tutoring system".

  On the second stage, for the selecting of publications, which present the results of
experimental studies in the field of adaptive learning systems, we composed a search
query consisting of four parts, combined by the logical operator AND:

1. keywords to select publications that address adaptive and personalized learning:
   (adapt* OR personali*);
2. keywords to select education related publications: (education* OR "tutoring" OR
   instruction* OR course*);
3. keywords to select publications related to educational information systems:
   ("learning environment" OR "learning system" OR "tutoring system");
4. keywords to select publications that show the results of surveying, questionnaire,
   and empirical studies and in the field of using adaptive learning systems: (evaluat*
   OR empiric* OR experiment* OR survey* OR questionnaire).

   Given the specifics of the query language of databases, as well as the additional
limitations pointed out, search queries were as follows:
   for search in Scopus:
TITLE-ABS-KEY (adapt* OR personali*) AND TITLE-ABS-KEY (education* OR
"tutoring" OR instruction* OR course*) AND TITLE-ABS-KEY ("learning environ-
ment" OR "learning system" OR "tutoring system") AND TITLE-ABS-KEY (evalu-
at* OR empiric* OR experiment* OR survey* OR questionnaire) AND (LIMIT-TO

3      Research Results and Discussion

To answer the first research question, "are issues of personalized and adaptive ICT-
enhanced learning up-to-date?", the search in electronic libraries and databases was
done.
   Analysis of data collected through selecting publications in abstract and citation
databases, as well as electronic libraries by the key phrases "personalized learning",
"individual learning", "direct instruction", "personalized e-learning", "adaptive
learning", "intelligent tutoring", "personalized learning environment", "adaptive
learning system", "intelligent tutoring system", leads to the conclusion that over the
last decade, researchers have paid considerable attention to the theoretical and practi-
cal aspects of personalized and adaptive learning, in particular to using of information
and communication technologies for provision of education adaptability (see Table 1).

The data got from the Scopus and Web of Science Core Collection abstract and cita-
tion databases reveal the dynamics of scientists' publication activity in the field of
personalized and adaptive learning by years. The results are given in the Table 2 and
Fig. 1-3. We can state a stable scientific interest for these issues. In particular, the
number of publications on most of the key phrases analyzed significantly increased in
2014.

The findings of the studies implied that scientists are interested in issues of personal-
ized and adaptive ICT-enhanced learning. So, we can state their significance for theo-
ry and practice of education.
   To answer the second research question "what are the ICT-means for personaliza-
tion of learning?", we examined some scientific papers devoted to using ICT for per-
sonalization of learning from the list selected on the previous exploring stage.
   In [19], Su J-M. develops the a rule‐based self‐regulated learning (SRL) assistance
scheme to intelligently facilitate personalized learning with SRL‐based adaptive scaf-
folding support for learning computer software [19, p. 536]. He defines five adaptive
scaffolding strategies and rule sets which are corresponding to planning, controlling,
monitoring, and reflecting phases [19, p. 540]. Moreover, researcher describes intelli-
gent learning environment built on these strategies, and gives examples of rule sets
use. Through an experimental research, he points out advantages of using approach
offered. In particular, one of them is the scaffolding strategies can be manageable and
extensible to support different learning subjects of computer software courses [19, p.
553].
   In [20], Rohloff, Sauer, and Meinel discuss the problem of content and learning
paths personalization in Massive Open Online Courses (MOOC). They state, that
MOOC platforms are oriented on providing knowledge numerous learners. But, this
approach is not very effective, and a lot of learners are not achieve their educational
goals. Researchers offer tools to integrate personalized learning objectives into
MOOC platform and facilitate students activities. Through the special interface,
learners select learning objectives which are subsequently supported by guiding the
learning with respect to the selected objective [20, p. 9].
   In [7], Turčáni and Balogh are considering a methodology for creating a personal-
ized e-course with the possibility of adapting to the learner in a special environment.
They offer an AdaptiveBook module for LMS Moodle which collects data about stu-
dents' activities and helps to build personal learning way.
   A recommendation module of an adaptive and intelligent web-based programming
tutoring system – Protus is described in [21]. As Klašnja-Milićević et al. state, tutor-
ing systems can contain two categories of adaptivity tools: (1) adaptive hypermedia
for course adaptation to learners' individual learning styles; (2) recommendation tech-
niques to suggest the most appropriate learning activities to learners [21, p. 886].
   The recommender framework offered by researchers contains three modules: (1) a
learner-system interaction module, which gathers data of learners activities to build
appropriate models; (2) an off-line module, which recognizes learners’ goals using
learner models; (3) a recommendation engine for producing a recommendation list
[21, p. 888]. To investigate learning styles across four dimensions (Information Pro-
cessing, Information Perception, Information Reception, Information Understanding),
authors use data collection tool - Index of Learning Styles by Felder and Soloman [21,
p. 889]. To evaluate benefits of using this recommendation module, researchers per-
formed an experiment while studying programming. They conclude, that experimental
results show positive effect of using proposed module.
   Some other approaches to personalization of learning are considered in [22; 23; 24;
25; 26].
   The following conclusions can be drawn from the results of the analysis:

• a person-centered approach is well developed in educational theory and practice.
  However, researchers are looking for new ways to implement it in order to achieve
  the highest degree of accordance learning content and means to person needs and
  opportunities and to provide conditions for lifelong learning;
• personalized and adaptive learning envisages the organization of the educational
  process when a comprehensive study of learner is carried out, then a model of one's
  possible development is constructed, and subsequent influences and interactions
  are built taking into account this non-static editable model;
• development of learner model is based on data about the learning style and other
  personal characteristics. Its collecting and further processing are complex process
  that requires the involvement of specialists in various scientific fields, as well as
  the use of information and communication technologies;
• organizing the distance learning process updates research on the issues of adaptive
  learning systems, among which we consider it advisable to highlight areas such as:
  improving the functionality of existing learning management systems, including
  the extended Moodle platform, to provide them with the means of personalizing
  learning (student analysis, personal characteristics) formation of individual educa-
  tional routes, adaptive delivery of educational content and assessment, etc.); pro-
  fessional training of specialists (psychologists, teachers, tutors) for the application
  of these systems in formal and non-formal education institutions.

   At the end, it is necessary to emphasize that individualized and adaptive learning
have an important significance for life-long learning development. There are some
reasons of this statement. Firstly, these approaches are based on learning styles mod-
els, and suppose satisfaction of persons' educational needs in different circumstances.
Secondly, using information and communication technologies helps to give access to
learning to widespread strata of the population.


4      Conclusion

The article presents the results of studying the state of research into the problem of
organizing personalized and adaptive learning, as well as the use of adaptive learning
systems. The study was conducted using the method of extensive search in electronic
databases.
    The analysis covered scientific publications for the years 2010-2019, presented in
the abstract and citation databases Scopus and Web of Science Core Collection, as
well as the electronic libraries of the Institute of Electrical and Electronics Engineers
and Association for Computing Machinery. The study consisted of two stages: 1)
search for a set of key phrases: "personalized learning", "individual learning", "direct
instruction"; "personalized e-learning", "adaptive learning", "intelligent tutoring";
"personalized learning environment", "adaptive learning system", "intelligent tutor-
ing system"; 2) search on a custom search query (adapt* OR personali*) AND (educa-
tion* OR "tutoring" OR instruction* OR course*) AND ("learning environment" OR
"learning system" OR "tutoring system") AND (evaluat* OR empiric* OR experi-
ment* OR survey* OR questionnaire). The results of the analysis of the generated
sample by years of publication, countries of origin of authors, number of citations are
presented in tables and diagrams.
    The resulting sample covers publications in influential scientific publications. The
refinements applied (time period, databases, key queries, search categories, etc.) limit
its scope and facilitate processing, but narrow the analyzed area somewhat.
    Taking into account the above perspective areas of research, further intelligence is
aimed at conducting a systematic review of literary sources, which presents the expe-
rience of teachers in the use of adaptive learning systems, as well as studying the level
of preparedness of teachers and higher education students in the field of knowledge
"Education / Pedagogy" in their use in educational process.
