        <p>Practical training is an integral part of the professional training of future teachers. During the practical training, trainees not only implement their own theoretical training in practice, but also increase the level of information competence. The rapid use of e-learning resources for distance learning during epidemiological constraints caused by biological threats poses new challenges to education in the availability of e-learning resources. The development of electronic educational resources is a dificult task, one of the ways to solve it is to involve future teachers in this process during the initial practice. The experiment of creating open educational resources by means of cloud technologies during the training practice showed the probability of solving this problem. Restrictions in direct contact between participants in the experiment, both due to epidemiological restrictions and through practical training in various educational institutions, are solved through the use of cloud technologies. The latter provides an opportunity to easily disseminate developed open educational resources and disseminate best practices in creating educational content.</p>

      <title>1. Introduction</title>
      <p>Information and communication technologies are a powerful tool for intensifying the educational
process and related organizational processes and activities within the framework of education
becoming more open. However, informatization and introduction of the latest tools, materials,
and tools into the educational process cannot be considered the ultimate goal of open education
and e-learning. Modern educational practice needs tools not only for publishing and storing
educational resources. It is necessary to have a developed set of tools for teamwork with a
variety of materials according to clearly defined criteria within educational systems that can be
used both in educational institutions and outside them. In addition to providing free access, it is
necessary to provide users with the opportunity to work collectively with materials, modifying
them and adapting them to the needs of their own educational activities.</p>
      <p>The initiatives of the University of T´’ubingen in Germany, the Massachusetts Institute of
Technology, and the Hewlett Foundation, launched in the early 2000s, have now evolved into
the Open Content Initiative or as Open Educational Resources (OER). We will use a term which,
in our opinion, is more successful “Open Educational Resources” or “Open E-Learning Resource”.
OERs are resources used to teach educational material, teaching materials, or research resources
that are in the public domain or have been released under an intellectual property license that
allows their free use or reassignment to others.</p>

      <title>2. Theoretical foundations of the study</title>
      <p>
        The development of open electronic resources is a complex and multifaceted problem. Specialists
of various specialties related to the theory of education, psychology, ergonomics, information
and communication technologies, etc. are involved in the creation of electronic educational
resources [
        <xref ref-type="bibr" rid="ref1 ref10 ref2 ref3 ref4 ref5 ref6 ref7 ref8 ref9">1, 2, 3, 4, 5, 6, 7, 8, 9, 10</xref>
        ]. A number of questions were asked about the process of
creating and using open educational resources by Wiley et al. [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ]:
• Do students assigned to create, revise, or remix artifacts find these assignments more
valuable, interesting, motivating, or rewarding than other forms of assessment? Why or
why not?
• Do students who make their assignments publicly available demonstrate greater mastery
of learning outcomes or show more enthusiasm for their work than students assigned
traditional assessments? Why or why not?
• Do students who openly license their work find additional learning benefits? Does openly
licensed student work produce additional benefits to the broader community?
• Are there any drawbacks (real or perceived) that are voiced by students or faculty that
participate in OER-enabled pedagogy?
      </p>
      <p>
        Partial answers to these questions can be found in the works of Velychko et al. [
        <xref ref-type="bibr" rid="ref12 ref13">12, 13</xref>
        ]. In
particular, in the work “Open Access to ICT and Electronic Educational Resources as a Guarantee
of Sustainable Development of Society” proposed stages of development of open electronic
educational resources during the educational activity (see figure 1 at [
        <xref ref-type="bibr" rid="ref13">13</xref>
        ]). Continuing the
study of this issue, we explored the possibility of creating open educational resources during
the initial practice by means of cloud technologies.
      </p>
      <p>Electronic learning resources are the foundation of e-learning, without such resources the
educational process cannot be an educational system. The advantages of open education are its
specific features, namely:
• information and communication technologies;
• technologies of interaction of participants of educational process;
• specialized teaching aids;
• network structures of organization and management;
• specific presentation of educational information;
• specialized quality control of education.</p>
      <p>Thus, open education is fundamentally diferent from traditional and more in line with the
goals, objectives and content of the information society. The main advantages of open education
include:
• mass and accessibility (open education has almost limitless possibilities of wide coverage of
the population and territories, organization of free access to information and educational
resources);
• adaptability and flexibility (the open education system has a wide range of opportunities
to adapt to changing environmental conditions, capable of significant transformations of
all important elements of the educational process);
• internationality and globalization (free functioning of the system of open education
outside state borders);
• planetary openness and availability of information and educational resources;
• modular structure and asynchrony (modular principle of constructing the content and
organization of the educational process allows to form individual curricula and programs
that best meet the personal needs of students, as well as to spread over time the various
elements of the educational process);
• economic eficiency (educational results are achieved with less, compared to traditional
education, time, money, etc.).</p>
      <p>Open educational resources according to the definition of “The General Conference of the
United Nations Educational, Scientific and Cultural Organization (UNESCO), meeting in Paris
from 12 to 27 November 2019, at its 40th session” defines Open Educational Resources (OER) are
learning, teaching and research materials in any format and medium that reside in the public
domain or are under copyright that have been released under an open license, that permit
no-cost access, re-use, re-purpose, adaptation and redistribution by others [14]. Open License
is a standard way of granting and restricting the rights to use, transform, reuse or distribute
creative results (sound, text, images, multimedia, etc.). Open licenses are designed to protect
copyright in environments where content (especially digital) can be easily copied and made
available for public access without the author’s permission. Open licenses are expected to help
guarantee permission to copy and share in a structured legal form, an approach that is more
lfexible than is available today, when all rights are automatically granted. Licenses in each
case provide certain rights, exempting from the restrictions of traditional copyright. OER is an
integral part of this process. OERs provide greater flexibility in the use, reuse, and adaptation
of materials to local contexts and learning environments, and authors receive well-deserved
recognition.</p>
      <p>Ukraine has a low culture of digital content consumption, as exemplified by the significant
percentage of unlicensed software use. According to The Software Alliance, the estimate
of unlicensed use of software in Ukraine in 2017 reached 80%, which is equivalent to $ 108
million, with an average of 57% in Central and Eastern Europe [15]. This culture of digital
content consumption also applies to electronic educational resources. Authors often face the
question from colleagues – how to protect the developed educational resources from illegal use.
Technological tools to limit digital content transactions exist, but they are unable to address
this issue at a fundamental level. The introduction of comprehensive digital content licensing,
we believe, will help to address this issue. Compliance with open licenses should help shape
the perception of licenses for digital content and the possibility of its use, depending on the
license. It is the obligation to license digital content that leads us to legal relations in the field of
electronic educational resources and to a civilized process of their creation, distribution and use.</p>
      <p>Open educational resources should not only have the appropriate licenses, but also a place
where they can be downloaded and downloaded, provide an assessment and describe the
experience of use. Like many digital content, open educational resources are stored in appropriate
repositories. Examples of open educational resources repositories include Open Discover Space
(https://portal.opendiscoveryspace.eu/en), MERLOT (https://www.merlot.org/merlot/) and OER
Commons (https://www.oercommons.org/). Unfortunately, there are no repositories in this area
in Ukraine. Universities, regional institutes of postgraduate pedagogical education, city and
regional departments of education create their own repositories. At the same time, repositories
take on a local character and do not have wide publicity in the educational environment.
Nevertheless, in Ukraine the pedagogical community is uniting and has opportunities to improve and
expand their professional competencies on open educational platforms “EdEra”, “Vseosvita”,
“Na urok”, “Prometheus” and others.</p>
      <p>Skills in working with open educational resources should be acquired while studying in a
higher education institution. Future teachers have a special advantage and responsibility.</p>
      <p>Practical training of future teachers is one of the important stages of the educational process.
On the one hand, during practical training, future teachers are able to implement the acquired
theoretical skills, and on the other hand, gain experience in practical work, which afects the
integrity of the existing competencies of future teachers. During practical training, especially
during the period of sanitary restrictions caused by biological threats, the role of information
and communication technologies increases during communication between students, mentors
and trainees, between trainees and supervisors, and between trainees to share experiences and
materials. The latter provides an opportunity to create tasks for the joint creation of electronic
educational resources and their joint use. Such activities are aimed at increasing the level of
formation of information, communication, organizational competencies. Tasks for joint creation
of electronic educational resources provide an opportunity to get acquainted with the means of
sharing digital content, practical use of cloud technologies, critical analysis of the suitability of
certain cloud technology services for the development and creation of electronic educational
resources.</p>
      <p>Cloud technology services have both advantages and disadvantages, we will single out
those that are critical to our tasks. The advantages include: no need for powerful computers
(relevant for providing educational institutions with modern computer equipment), losing the
meaning of using unlicensed software (relevant in the absence of such an item of expenditure),
mobility of use (from any suitable network point), the ability to work together on documents.
The disadvantages of cloud services in educational activities include: dependence on Internet
connection (stability of broadband access is critical for collaboration on documents), not every
cloud application provides the ability to save the results in a user-friendly form on the desired
media, there is a risk that the cloud service provider will terminate the service. And if you need
to take full advantage of cloud services, you need to prepare for the disadvantages of having an
alternative Internet connection, using open data formats and saving them, even with another
cloud service, creating backups.</p>
      <p>The concept and phenomenon of joint activities are actively studied by psychology and
pedagogy. When considering the concept of “joint activity”, attention is paid to two aspects: the
subject activity and the processes of forming connections between people who participate in
activities and communication. The main “unit” of the analysis of joint activities and its collective
subject is the interaction of participants in joint activities. At the heart of the dynamic concept
of joint activities is a conceptual “triangle”, which combines three areas:
• subject-oriented interaction (interaction aimed at changing the subject of joint activities);
• entity-oriented (interaction aimed at changing the characteristics of the individual subject
of joint activities);
• organizational-oriented (interaction, changing ways and style of performing activities).</p>
      <p>Considerable attention is paid to the impact of joint activities on intellectual development,
the formation of social intelligence and social competence of the subject of education. For all
the development of the concept of “joint activities”, the organization of such activities is not
considered in terms of developing technical means that specifically support and strengthen the
joint nature of activities. In this regard, the concept of “joint network activity” develops the
concept of “joint activity”, including special network tools. Joint network activity requires its
design based on the following conditions:
• the availability of new pedagogically sound technical means of joint activities on the
Internet, which open opportunities for enriching the activities of programs, objects, data
and communications;
• the presence of new organizational forms and scenarios of educational network activities,
focused on the formation of participants in the joint activities of the social network.</p>
    </sec>
    <sec id="sec-3">
      <title>3. Research results</title>
      <p>Pedagogical practical training should be considered as a type of practical activity of students
aimed at solving various pedagogical problems. The specificity of this activity is that it identifies
with the professional activities of teachers. At the same time, pedagogical practical training is a
form of professional training in a higher education institution, the purpose of which is:
• to deepen and consolidate the theoretical knowledge that the student received at the
university, and learn to apply this knowledge in practice in educational work with
students;
• to equip students with the ability to observe and analyze the educational work carried
out at school with students;
• to prepare students for lessons with the use of methods that enhance the cognitive activity
of students;
• to develop and consolidate in students a love for the teaching profession, to encourage
the desire to study advanced pedagogical experience and improve their pedagogical skills.</p>
      <p>Various educational institutions and epidemiological restrictions make their adjustments in
the process of practical training. It was a good practice from time to time to gather in a higher
education institution and discuss problematic issues with classmates and methodologists, share
experiences and more. The present requires communication and common tasks at a distance.
To solve this problem it is necessary to use information and communication technologies and
means of joint activities. Cloud technologies will be useful for the implementation of the set
tasks. Using cloud technologies, we are able to establish communication and common places to
work in groups.</p>
      <p>Tasks ofered to students of educational programs 014 Secondary education (Mathematics),
(Physics), (Computer science) of the Faculty of Physics and Mathematics of Donbas State
Pedagogical University, who underwent training and production practice in general secondary
education institutions of Donetsk, Kharkiv, Luhansk and Dnipropetrovsk regions provided
for three areas of activity: the creation of joint electronic educational resources, information
visualization, organizational online platforms.</p>
      <p>The use of presentations, even made in dynamic systems, do not provide an opportunity to
involve students in active learning. Quite diferent opportunities are provided by whiteboards,
thanks to which in the online format of learning the participant of the educational process takes
part in discussing problems, solving problems, etc. We selected and ofered 10 cloud services to
create training material for the training session (table 1). Before the classes, the trainees had to
get acquainted with the proposed list, explore the functions and capabilities of each of these
cloud facilities and create training material for the class. For comparison, the trainees prepared
the teaching material in the form of a presentation and demonstrated it to the students, while
the students performed the tasks on paper. After the lesson, students were asked which of the
suggested options for the lesson they liked the most. The survey of the class showed that 70.0%
of the surveyed students out of 374 who took part in the survey preferred the lesson where the
“whiteboard” was used.</p>
      <p>To visualize the information and create interactive content, the systems presented in table 2

were studied. Visibility is one of the conditions of electronic educational resources. The
development and creation, even of static, e-learning resources is one of the tasks of e-learning.
The limited space available for inspection requires the use of presentation technologies in the
form of scrolling. Accordingly, the method of their application should change, in contrast to the
fact that students see a large paper poster. The constant use of the same patterns, design styles,
etc. in educational activities leads to a loss of visual interest in the educational material. The
use of various design styles, fonts, icons, etc. increases students’ visual activity. Each of the
proposed systems has its own unique design style. Even by creating infographics in diferent
systems based on common data, we get fundamentally diferent digital products.</p>

      <p>Practitioners faced the problem of downloading created digital objects to their own device.
At the same time, their integration into other objects created by cloud technology applications
took place without hindrance. The above applications of cloud technologies at the beginning of
their founding mostly ofered their resources for free, with the growth of their popularity, most
of them switched to the financial model “Free – Premium” (Freemium), where some services are
provided on a free basis and some on a commercial basis. However, for each of the applications,
we were able to obtain a digital object created by us on our own computing device by third-party
tricky methods.</p>
      <p>The created means of visual presentation of data were used during educational activities.
Moreover, students in computer science lessons and outside the classroom were asked to create
their own posters, charts, graphs, infographics. The study involved 362 students, of whom
235 students (about 65%) liked to create digital content of this type. The students included the
advantages – “beautiful”, “visual”, “useful”. Among the shortcomings were noted – “not clear”,
“dificult”, “I have no artistic flair”. Analyzing the answers to the shortcomings, it should be noted
that they do not have a meaningful basis, they are answers-justification of their unwillingness
to use the proposed applications of cloud services. Regarding the reasons for reluctance, the
study was not conducted due to lack of time during the internship.</p>
      <p>We also asked the students – “What is the main thing in the application in your opinion?”.
The obtained answers are presented in figure 1. Most students (32.6%) were inclined to think
about “understandable language” used in the application. Despite the availability of cloud online
translation services, the interface in English caused dificulties when using the application. In
second place (28.2%) was the ability to work as a mobile application, because today the number
of users through mobile systems exceeded the number of users through a stationary computer
system. In third place was the design criterion (23.5%). And although the systems that were
proposed were directly related to graphic design, the ergonomics of these systems still need
to be improved. In last place was the criterion of “available examples of work” (15.7%). In our
understanding, this is the “worst” criterion and it is gratifying that the smallest number of
students is ready to do tasks on the model, because the capabilities of the systems are suficient
for creativity and creative presentation of information.</p>
      <p>The task of creating shared electronic resources was to analyze existing cloud applications
to create presentations and text documents. To do this, the use of ofice applications for cloud
services was proposed, which is presented in Table 3. In contrast to the previous comparison
tables, the advantages and disadvantages collected from the subjective judgments of trainees
were considered. It was in these applications that they tried to create electronic educational
resources, which were then to become open educational resources. It should be noted that while
the interns were already familiar with the Google Docs and Ofice Online systems, the Zoho
Ofice Suite and ONLYOFFICE turned out to be surprisingly interesting and useful. It was in
these ofice applications that interns tried to create electronic educational resources. Tasks were

proposed for groups of three students and the selected topics were similar in content.</p>
      <p>After the end of pedagogical practice, a survey of students on the joint creation of open
educational resources was conducted. They were asked the following questions:
A. How do you feel about open digital content (Positive / Negative)?
B. Did you have experience of using open educational resources during pedagogical practice
(Yes / No)?
C. Have you used digital resources despite not having this action with a license agreement
(Yes / No)?
D. Are you ready to create open educational resources (Yes / No)?
E. How do you feel about the joint development of electronic educational resources (Positive
/ Negative)?
F. Is it appropriate to use unlicensed software to develop open educational resources (Yes /</p>
      <p>No)?
58 students of the Faculty of Physics and Mathematics of Donbas State Pedagogical University
took part in the survey. The results of the survey are presented in figure 2. Questions A–C
were related to the use of open educational resources, and questions D–F were related to their
development. We tried to determine whether students would be willing to use open educational
resources to develop them. Using the Mann – Whitney U test, we compared the responses in the
two groups (A–C) and (D–F). The results of calculations  = 18, 0.1 = 3.0, 0.05 = 7.0
indicate the absence of significant diferences between groups, and therefore students who are
willing to use open educational resources are ready to develop them.</p>
      <p>The analysis of the answers tells us about one unpleasant point, which is mentioned in
questions C and F. Students do not pay much attention to the issue of licensing a digital product,
and it does not matter whether it is an electronic educational resource or software. To justify it,
it should be noted that similar surveys conducted three years ago about free software spoke of
an even worse attitude to the licensing of software.</p>

      <title>4. Conclusions</title>
      <p>Open educational resources are a product of the digital world, which has a huge potential
for further achievement of UNESCO’s goals in the field of education. They help countries,
institutions and teachers to share quality education and materials free of charge. They challenge
teachers to integrate digital technology into their courses and programs, and enable students to
access quality content ofline. They are also an incentive for teachers, students and institutions to
work together to create original material. It is important that governments use OER opportunities
for their socio-economic development purposes. UNESCO can assist in this process by issuing
Recommendations that will encourage governments to develop strategic policies to engage OER
in the core system of their education systems, encouraging institutions to take full advantage of
this development to achieve global development goals.</p>
      <p>The result of creating open electronic resources in the interaction of future teachers during
the internship was not only the availability of educational content, but also increasing the level
of professional competencies in ICT, collective interaction, project activities, creative thinking.
The results of the surveys indicate the need to continue this practical activity with the study of
the criteria for the efectiveness of the use of open electronic resources and their quality.
