        <p>The article deals with the use of cloud technology services in the study of free software. Free software is a social phenomenon based on the philosophy of freedom and the right to intellectual creative activity. To date, a significant number of software products have been created that are licensed under free software and not used in educational activities. The conducted research revealed the factors promoting and hindering the use of free software in educational activities. Conducted questionnaires, analysis of open data, research of scientists made it possible to conclude on the expediency of using free software in educational activities. Cloud technology is not only a modern trend of effective use of information and communication technologies in professional activity, but also a proven tool for educational activities. To get acquainted with the free software, the use of cloud technologies has been helpful, which is the goal of our research.</p>

      <p>Modern teaching methods involve the use of information and communication
technologies (ICT) in the educational process. The use of ICT has not only changed the
methods of traditional learning, redistributed priorities between forms of learning, but
new forms of learning have emerged. For any method or form of training that uses high
information technology, software is required, without which the technologies lose their
meaning. From the interactive whiteboard controller application to multimedia
application creation and distribution programs on the World Wide Web.</p>
      <p>Free software is a significant feature of the computer industry. Launched as a
philosophical concept, free software has not only found its adherents, but also has a
large number of software tools used in various directions in its arsenal. The pedagogical
universities are use in educational activity: systems for the organization of distance
education MOODLE, ILIAS is not an exception; computer mathematics systems
Maxima, Octave, GAP, SAGE, SPP; GIMP, Inkscape graphics packages; OpenOffice,

widespread use in educational activities remains. One possible solution to this problem
is to study free software using cloud technology services.

      <title>Results of the study</title>
      <p>Open Education Ideas provide free access to e-learning resources for everyone to learn.
Such access is provided by ICT based on free software.</p>
      <p>Our research has allowed us to identify the factors that hinder and facilitate the use
of free software. One of the stages of the study was to conduct an anonymous survey
of higher education teachers regarding the use of free software in their professional
activities. The developed questionnaire as a form was made freely available
(https://goo.gl/forms/F0BVkSnvwpHTo6H82) using Google Forms, a link to which
was circulated via the “Krivorozhsky Conferences and Seminars”
(https://groups.google.com/group/cc_seminar) and “Scientific journal Physical and
mathematical education” (https://groups.google.com/group/fmo-journal).</p>
      <p>The data collected allowed us to determine the following results. 92% of respondents
teach science and mathematics. Young teachers, who already have experience in
teaching, predominate by age (Fig. 1). 93% use free software in their professional
activities. 95% recommend free software to their students for extracurricular activities.</p>
      <p>Considering the benefits of using free software, the following were highlighted for
conducting the questionnaire:
─ legal (licensed purity, non-discrimination, etc.);
─ technical (open standards, increased security, vendor independence);
─ training (providing the necessary functionality, open source);
─ social (trend, modern gadgets).
Respondents identified the following factors as facilitating the use of free software
(Fig. 2): legal preference was given the highest importance (78%). This result is
predictable. According to estimates of the Software Alliance (bsa.org), 82% of the
software used in Ukraine is not licensed purity.</p>
      <p>75% of the respondents chose among the advantages of free software its educational
attractiveness. This result indicates that sufficient free software is available for
educational activities. Also important is the availability and openness of software
source code.</p>
      <p>The analysis of the survey answers indicates that there are technical advantages of
using free software in the process of training future professionals. This is noted by 65%
of respondents. Open storage standards are an important factor in the software selection
process. This gives you confidence in the continued use of your own work. User gains
independence from software developers.</p>
      <p>The low percentage (33%) belongs to social preferences. The reason is marketing
policy. When promoting new high-tech devices, it does not emphasize that their work
is based on free software because of its low social popularity.</p>
      <p>The survey revealed a number of shortcomings in the use of free software in
educational activities (Fig. 3). We identified the shortcomings in the following groups:
─ financial (funds for migration, training, etc.);
─ technical (changing the format of existing data, support for peripherals);
─ software (lack of specialized software);
─ methodical (lack of methodological support for application).
The lowest percentage (20%) belongs to financial expenses. This low level of concern
about financial issues is due to the lack of responsibility for the use of unlicensed
software.
42% of respondents are not aware of its existence and localization of specialized
software. GitHub.com (64 million projects), SourceForge.net (430,000 projects),
bitbucket.org (170,000 projects), CodePlex.com (108,000 projects), launchpad.net
(41,000 projects), Savannah.gnu.org (4,000 projects), Gna.org (1,500 projects) hosted
a large number of free software products.</p>
      <p>The downside of free software is technical issues. These include the transition to
new file formats (open file formats) and software for working with peripherals. This
concern was expressed by 55% of respondents. Open file formats are currently well
developed. Proprietary and closed form owners are taking steps to legalize their
openness due to the development of open file format standards. User-generated data
can be stored and used for a long time. Users need to have confidence that they can be
used for a considerable period of time. Own data must be created using open file
formats.</p>
      <p>You can estimate the popularity of using file formats by analyzing the approximate
number of indexed documents published on the Internet. It is obvious that open file
formats are used by both free and proprietary software. However, the results obtained
from the number of documents indexed by the search engine (Table 1) indicate the
popularity of open file formats.</p>
      <p>A technical problem is the variety of peripherals and the lack of peripheral software.
Peripheral developers are trying to keep the technology developed secret. The necessary
technical information is not provided for public use. This fact makes it impossible to
create free software for peripherals.</p>
      <p>The biggest drawback is the lack of methodological support for the use of free
software in educational activities. It was identified by 62% of respondents. The lack of
free software at the beginning of the informatization led to the installation of proprietary
system software as the base. Therefore, proprietary application software has also
become widespread. Methodological support for the use of software exists in most
proprietary software. Today, the situation with the use of free system software has not
improved. According to the StatCounter resource (http://gs.statcounter.com), only
1.53% of desktop computers in the world have the Linux operating system installed.</p>
      <p>The situation is similar in Ukraine. Only 1.42% of desktop systems are running
Linux. However, the situation is beginning to change. The results of scientific and
methodological research on the use of free software in education are presented at the
annual FOSS Lviv conference (http://conference.linux.lviv.ua/) and more [42; 43].
Thus, at the Luhansk Taras Shevchenko National University, pre-service teachers of
Mathematics, Physics and Computer science study the Linux operating system, the
Maxima computer mathematics system and the Lazarus, Geany programming
environment. At Pavlo Tychyna Uman State Pedagogical University, the course
“Computer Network Administration” is taught on the Linux operating system. Nizhyn
Mykola Gogol State University uses the OpenOffice.org software, Hot Potatoes, to
study the subject of Electronic Information Processing. The basic discipline of “PC
operating systems” is taught using the Linux operating system as a complete alternative
to the proprietary Windows system. The courses “Using Information Technology in
Education and Science”, “School Computer Science and Teaching Methods”
demonstrate the possibilities of using OpenOffice.org and Scribus as an alternative to
Microsoft Office, GIMP as an alternative to Adobe Photoshop, Inkscape as an
alternative to CorelDraw and more.</p>
      <p>GeoGebra Institute operates at the Department of Informatics at H. S. Skovoroda
Kharkiv National Pedagogical University. The National Technical University of
Ukraine “Igor Sikorsky Kyiv Polytechnic University” operates the “Linux Professional
Institute” (LPI). At the Bogdan Khmelnytsky Melitopol State Pedagogical University,
there are such disciplines as “UNIX-like operating systems” and “Programming for
open systems” in the bachelor’s curriculum.</p>
      <p>At the Poltava V. G. Korolenko National Pedagogical University is widely used by
GIMP when teaching Computer Graphics and Design, and geometry is supported by
Maxima Computer Mathematics. The Maxima computer mathematics system is also
widely used in the teaching of students of Physics and Mathematics at Ivan Franko
Drohobych Ivan Franko State Pedagogical University.</p>
      <p>At Sumy State Pedagogical University named after A. S. Makarenko uses software
products such as GeoGebra, Dr Geo, C.A.R., Kig and KSEG to train future math,
physics and computer science teachers. At the National Pedagogical Dragomanov
University systems of computer mathematics Maxima, Sage, Scilab, Scidavis and many
others are used in the study of the disciplines of mathematical and informative cycles.
Teachers of Kryvyi Rih State Pedagogical University base their teaching on the
Maxima computer mathematics system for basic mathematical training of future
teachers of mathematics, physics and computer science. All of the above software
products are free software products.</p>
      <p>The expediency of using free software in the educational process of future
professionals is quite high. Free software gives freedom to its users to choose to use
and study both the free software products themselves and their applications. It is a direct
factor in stimulating the desire for learning and self-education. The use of free software
in the training of future professionals will increase the level of information culture, will
teach themselves to choose forms and methods of education, will form skills for the use
of free software in further professional activity, will be able to be competitive in the
labor market and meet the requirements of social ordering information society in the
modern specialist.</p>
      <p>To get acquainted with the free software, it is not necessary to download it to your
own personal device. You do not have to visit the computer systems labs where the
appropriate software is installed. Cloud technologies make it possible to use the
software as a network service. OffiDocs Cloud (https://www.offidocs.com/) is a
flexible and powerful platform. It allows you to browse the web with applications using
only a web browser. OffiDocs provides users with Internet applications for any device
(desktop, tablet, mobile, etc.) such as LibreOffice, GIMP, Dia, AudaCity, OpenShot
and many more through a web browser.</p>
      <p>A prerequisite for using a cloud service is logging in with an ID. This account creates
an account. It is available from any cloud application. Cloud applications are
categorized as productivity, images &amp; graphics, video &amp; audio, messaging, education,
games, utilities, programming.</p>
      <p>Each of these sections of the cloud application is noteworthy. Just as interesting are
mobile apps, extensions, resources and templates. Let's take a closer look at the
cloudbased LibreOffice suite of services included with the file manager. It is worth noting
that there are two options – the first (Fig. 4) is adapted for use in browsers, and the
second, launching applications with Gnome interface with image translation in the
frame of a hypertext document. Cloud service integration includes integration with
Google Drive and Dropbox cloud file repositories.
With the ability of a cloud-based environment to study free software, it becomes
available to perform standard operations to create electronic educational resources.
There is a possibility to use various ways of registration of the textual information
(styles, fonts, font sizes, etc.). Text documents and presentations can be supplemented
with illustrations (you can use the resource http://editor.pho.to/en/edit/ to process the
illustrations). Once created, documents can be downloaded to your own device in ODT,
PDF, and more. With http://odfviewer.nsspot.net/ you can view downloaded documents
in ODT format. Use the https://smallpdf.com/edit-pdf service to view and compare
PDFs visually.</p>
      <p>Image creation, video editing and audio editing programs are just as functional. The
typical task of using this cloud application is to create an online educational resource
for one of the training topics using the learned applications.</p>
      <p>Another cloud service that allows you to get acquainted with free software is the
service https://www.rollapp.com/ (Fig. 5). In this dream, educational applications,
utilities, office applications, games, graphics applications, development programs are
available to users. Free software is available for use in this cloud after user registration.
In addition, there is a rating system for evaluating the available software by users.</p>

      <title>Conclusions and prospects of future research</title>
      <p>The results of the long-term use of the OffiDocs cloud service at the Faculty of Physics
and Mathematics of the Donbass State Pedagogical University testify to its wide
opportunities to become acquainted with free software and its use in the educational
activities of pre-services teachers of mathematics, physics and informatics. The
availability of alternatives to cloud applications from Google and Microsoft allows us
to study information technology rather than specific software. It is not necessary to
study the software interfaces, as they are intuitive. The latter provides the opportunity
to fundamentally train information and communication technologies and to prepare
future professionals for further professional activities.</p>
