      <title>1. Introduction</title>
      <p>
        The motivation for this research stems from two interrelated factors. First, the increasing
demand for digital learning aids that can support the emerging modes of blended and distant
learning in contemporary education at all levels [
        <xref ref-type="bibr" rid="ref1 ref2">1, 2</xref>
        ]. The design of such digital aids requires the
adoption of progressive approaches that are aligned with the prospective educational paradigms.
Second, the challenge of preparing pre-service specialists for life and successful work in the
volatile world of today, which calls for the modernization of the vocational training process in
various domains [
        <xref ref-type="bibr" rid="ref3 ref4">3, 4</xref>
        ]. The current situation with the vocational training is exacerbated by
the unexpected circumstances caused by the global pandemic and the urgency of developing
new forms of teaching and learning. Therefore, it is important to build a renewed model of
vocational training based on new paradigms.
      </p>
      <p>One of such paradigms is the holistic educational approach, which is emphasized in a number

of normative documents, such as the Concept of the New Ukrainian School [
        <xref ref-type="bibr" rid="ref5 ref6">5, 6</xref>
        ], the National
Strategy for the Development of Education in Ukraine for 2012–2021, the Law of Ukraine “On
Higher Education”, the Law of Ukraine “On the Concept of National Education information
programs’’, Education for Sustainable Development Goals: Learning Objectives and others.
According to recent research papers on the theory of holistic education, it is considered as a
paradigm that provides educators with a system of principles that can be applied in various
ways [
        <xref ref-type="bibr" rid="ref7 ref8 ref9">7, 8, 9</xref>
        ]. The central idea of holistic education is the cohesive development of the whole
personality of a learner at both the intellectual and emotional levels [
        <xref ref-type="bibr" rid="ref10">10</xref>
        ]. It is also emphasized
that such a cohesive development should be supported by strong links between personal
experience and real-life problems. However, the evidence from real educational practice shows
that the productive and important ideas of holistic paradigm are often implemented in a limited
way without fully exploiting its potential for providing integrity at the levels of the content,
means and forms of education.
      </p>
      <p>In this research, we aim to implement holistic approach in a comprehensive way, covering
various aspects of vocational training, such as: (1) designing the educational content based on
the integrative approach to structuring the curriculum disciplines; (2) providing multi-code
representation of the educational content to stimulate cognitive processes; (3) integrating
students’ educational practices with innovative ICT applications to real-life challenges through
project-based learning. We argue that these aspects are both driven by and complementary to
each other, and thus they enable a more holistic understanding and practice of education.</p>
      <p>We also contend that the realization of the main principles of holistic theory requires an
appropriate system of learning aids that can facilitate the cohesive development of learners’
personality. This leads us to develop digital aids based on the functional approach, which is
regarded as the most advanced approach to their design.</p>
      <p>
        In this context, it is essential to prepare IT specialists of various directions (including potential
IT teachers) for designing and implementing efective didactic aids that are based on the analysis
of their functions and that can support holistic learning of diferent subjects at diferent levels of
education [
        <xref ref-type="bibr" rid="ref11 ref12 ref13">11, 12, 13</xref>
        ]. Therefore, one of the important components of the renewed model of IT
specialists’ vocational training based on the holistic approach is the students’ project-oriented
activity on creating digital learning aids.
      </p>
      <p>The aim of this paper is to present the practical aspects and outcomes of applying the
functional approach to the development of contemporary digital learning aids in the process of
project-based activity of pre-service IT specialists within their holistic vocational training.</p>

      <title>2. Theoretical framework</title>
      <p>To conduct this research, we employed a combination of theoretical, empirical, and modelling
methods. In the proposed model of pre-service IT specialists’ training based on the holistic
approach, their preparation for designing innovative didactic aids is realized comprehensively
through the integration of common and vocational curriculum disciplines and project-oriented
activity.</p>
      <p>The theoretical background of the research in the field of digital learning tools development
consists of two main components: the holistic educational approach (briefly discussed above)
and the functional principles of digital didactic aids design.</p>
      <p>
        The issues of defining didactic functions of learning aids and applying functional approach
to their design have recently attracted the attention of researchers and practitioners (e.g.,
Grinshkun et al. [
        <xref ref-type="bibr" rid="ref14">14</xref>
        ], Grinshkun and Usova [
        <xref ref-type="bibr" rid="ref15">15</xref>
        ], Gryzun [
        <xref ref-type="bibr" rid="ref16 ref17">16, 17</xref>
        ], Kraevskii [
        <xref ref-type="bibr" rid="ref18 ref19 ref20">18, 19, 20</xref>
        ], Lerner
[
        <xref ref-type="bibr" rid="ref21">21</xref>
        ], Kuts and Lavrentieva [
        <xref ref-type="bibr" rid="ref22">22</xref>
        ], Lerner [
        <xref ref-type="bibr" rid="ref23">23</xref>
        ], Robert et al. [
        <xref ref-type="bibr" rid="ref24 ref25">24, 25</xref>
        ] and others). This approach is
based on a thorough analysis of the didactic functions of the learning aids and the means of their
realization. Functional approach to creating learning aids enables to determine the functional
load of its structural elements and the connection between the performance of their required
functions [
        <xref ref-type="bibr" rid="ref16 ref17 ref21 ref26 ref27 ref28 ref29">16, 17, 21, 26, 27, 28, 29</xref>
        ]. These ideas become increasingly relevant nowadays in the
context of designing digital multimedia tutorials [
        <xref ref-type="bibr" rid="ref30">30</xref>
        ], as they play a vital role in education.
      </p>
      <p>The problem of didactic functions analysis has always been complex and ambiguous. There
are various views on their nature and classification. Based on the review of a number of sources
that represent a wide range of functions, we could identify certain groups of them that seem
to be pertinent for digital aids. Specifically, the first group includes functions that enhance
learning motivation; the second group contains pure didactic functions that provide efective
representation of the learning content and its successful assimilation; the third group includes
functions of optimization of educational process in terms of adaptation to the learners’ needs;
the fourth group consists of meta-functions that foster learners’ progress and increase their
general educational potential, which creates a basis for further successful learning beyond
the knowledge domain covered by this specific digital aid. It is important to note that these
groups of functions are general in nature. Depending on the target audience of the digital aid
(schoolchildren or students), the type of academic discipline for which the aid is developed, and
some other factors, the emphasis and priorities of these groups of functions may vary.</p>
      <p>Nevertheless, the functional analysis for a specific digital learning aid provides practical
guidelines for developing the structure of e-tutorials that can be used as a theoretical foundation
for their design. The design process involves determining the structure of the tutorial that
specifies the interrelations of its components, establishes the mechanism of implementation of
these links, etc. As mentioned above, the process of contemporary tutorials development must
rely on their deep understanding as an object of design. Thus, it is relevant to acknowledge
that a digital learning aid in its state-of-the-art sense has been transformed into an integrated
learning environment that incorporates functions of a whole set of learning aids. This has
happened due to the use of advanced multimedia and cloud-based technologies in its design.</p>
      <p>In addition to determining the structure of a digital aid and clarifying the functional load
of each of its structural components, the functional approach also helps to formulate specific
requirements for the aid and its design features. This makes the process of the aid development
more practically oriented, which is very beneficial for the students’ project-based activity, as it
gives them a clear understanding of the objectives and significance of their work, enhances their
motivation to design high-quality aids that meet the requirements derived from the functional
analysis.</p>
      <p>The above-mentioned theoretical background provided a basis for applying the functional
approach to the development of contemporary digital learning aids in the process of
projectbased activity of pre-service IT specialists within their holistic vocational training.</p>
    </sec>
    <sec id="sec-3">
      <title>3. Results and discussion</title>
      <p>The practical aspects and experience of this kind of activity are covered below on the examples
of the development of diferent digital learning aids provided by the students of diferent
specialities within their project-oriented activity in the process of their holistic training.</p>
      <p>In particular, we would like to represent multimedia tutorial for English learning support
which was designed by the pre-service teachers of Computer Science and English in the
process of their project-oriented activity, rested on the previous learning of such curriculum
subjects as Programming, Computer Graphics, Pedagogy, English (common academic subjects)
and Computer-oriented systems of learning, Basics of E-pedagogy, Design of didactic aids
(professionally-oriented subjects).</p>
      <p>On the initial stage of the project the didactic functions and structure of the multimedia
tutorial were specified due to needs and problems of foreign languages mastering at school.</p>
      <p>In particular, pre-service teachers revealed basic demands to the tutorial, determined its
functional facilities and defined its structure. In such a way, there was concluded that in order
to provide the fulfilment of the leading didactic functions, the English multimedia tutorial for
6th grade pupils has to realize the set of facilities that are given below with the reference to the
groups of functions (see “Theoretical framework” section).</p>
      <p>First of all, it must provide high-quality visualization of educational content and interactive
dialogue with a trainee. It will help to realize in proper way informational, transformational,
developing didactic functions (the second group of functions), as well as functions of feedback,
friendly correction (the first group of functions) and control (the third group). It should also
ensure that the acquisition of linguistic competence is enhanced by the complex involvement of
many information perception organs, which will provide the implementation of transformational
and developing functions.</p>
      <p>The tutorial also has to enable working out of various skills of speech training and in such a
way to realize systematic and consolidation functions (the second group of functions). It should
guarantee the cognitive activity management including game activity for ensuring realization
of didactic functions of developing and self-learning (the fourth group). In addition, the tutorial
must provide a strong feedback with a teacher and other trainees to obtain consultations, help,
assessment etc (the second group of functions).</p>
      <p>Finally, the tutorial has to be easily integrated with other e-resources which will guarantee it
integrative and coordinative didactic functions (the third group of functions).</p>
      <p>
        Based on the above functions and relying on research [
        <xref ref-type="bibr" rid="ref21 ref28 ref31 ref32">21, 28, 31, 32</xref>
        ], it became possible to
design the structure of the multimedia tutorial, since it is conditioned by the need to implement
its didactic functions. Thus, students concluded that the tutorial should be the complex of
interconnected components characterized below.
      </p>
      <p>
        For high-quality information visualization, the tutorial should include a multimedia
illustration library that ofers text, graphics, video, and audio materials [
        <xref ref-type="bibr" rid="ref33">33</xref>
        ].
      </p>
      <p>To build language competence via the comprehensive involvement of many sense organs,
the tutorial contains an interactive video library with didactic support.</p>
      <p>To develop a variety of skills, the manual has a bank of interactive exercises with an immediate
output of the results of their implementation.</p>
      <p>For learning activity management, the tool has a learning activity management component
with repetition of the material and involvement of game elements.</p>
      <p>To automate the processes of information retrieval and integration with other electronic
sources, the manual has a technological component that will provide its online uploading and
the ability to be integrated with other resources. To communicate with the teacher and other
students, the tutorial has an appropriate component.</p>
      <p>Defined and specified didactic functions and structure of the multimedia tutorial became the
basis of its design for the students.</p>
      <p>Thus, on the subsequent phases of the project the multimedia English tutorial for 6th grade
schoolchildren has been developed with the help of the tools of Ourboox environment, whose
capabilities were enhanced by the students’ programmed elements. It’s worth noting that it does
not need to be installed or downloaded due to the fact that it is a cloud-based multimedia book
called MultiEnglish. It covers the main topic taught in the 6th grade during English lessons:
My family, My friends, Shopping, Food, Sport, Traveling, Ukraine, Great Britain, School life
(figure 1).</p>
      <p>Each topic is represented in four headings (Let’s focus on…) that target formation and
development of four basic language skills: Let’s focus on Vocabulary, Let’s focus on Reading, Let’s focus
on Grammar, Let’s focus on Listening and Speaking, Let’s focus on Writing (figure 2). The
sections contain relevant teaching materials, questions, tasks and various exercises. The demo
version of the tutorial is available via the link https://www.ourboox.com/books/multimediaenglish/.</p>
      <p>While designing the tutorial, according to its didactic functions and structure, standard
features of the Ourboox environment have been significantly extended by HTML markup
programming.</p>
      <p>Adding appropriate language instructions allowed students to supplement the tutorial with
interactive elements of other services that are not provided by the Ourboox environment toolkit.
In particular, training exercises, interactive videos, interactive posters, games, static and dynamic
illustrations, hyperlinks of a number of services (LearningApps, Quizlet, YouTube, Edpuzzle,
Vizia, Gettyimages, ThingLink, ESL Game Plus, Jigsaw Planet, Google Forms) were integrated
into the tutorial (figure 3).</p>
      <p>In addition, due to editing the HTML code of the tutorial pages, the media content was
created. For example, the students-developers could combine text, graphics, video elements
and the necessary hyperlinks. Using HTML, it was enhanced Ourboox’s capability to format
text. For example, it was developed code fragments in HTML with CSS elements to align text
and to create numbered lists. In addition, students-developers programmed integration with
interactive didactic support into the tutorial. This element allows a trainee to watch the video
with a pause at the marked places and do interactive tasks to the video story.</p>
      <p>On the whole, thanks to the programmed elements that were added, the multimedia tutorial
is able to perform all its didactic functions, defined at the first (theoretical) stage of the students’
project.</p>
      <p>At the final stage of their project, pre-service Informatics teachers do analysis and reflection
of the designed tutorial, revealing its didactic features.</p>
      <p>Discussing the didactic capabilities of the MultiEnglish multimedia tutorial, designed on
the basis of a functional approach by the pre-service Informatics and English teachers at their
project activity, we would emphasize its following features.</p>
      <p>The tutorial provides high-quality visualization of educational information and interactive
dialogue with the student. A vast library of multimedia illustrations of the application visualizes
the necessary elements of the educational content and provides instant feedback. The library
contains static and dynamic illustrations of various types, including interactive posters. This
type of illustrations enables quick boosting and checking a trainee’s vocabulary (figure 4).</p>
      <p>This tutorial capacity provides high-quality implementation of informational,
transformational, developing didactic functions, as well as the functions of feedback, correction and
self-control. In addition, the tutorial enhances the efectiveness of language competencies
through the comprehensive involvement of multi-senses activities. In particular, the tutorial
allows you to organize the learning activities of the student with interactive video stories, for
which it has been developed appropriate didactic support. Thus, while viewing the pupil is
provided with the tasks that develop their audio skills, replenish their vocabulary, encourage
the conscious using of grammar (figure 5).</p>
      <p>The multimedia tutorial also has the ability to record a student’s speech in order to develop
their oral speaking and communication skills (figure 6), which provides realization of the
transformational and developing functions.</p>
      <p>The developed digital aid encourages training of various skills and can be used as a simulator.
The Bank of interactive exercises ofers the trainee a variety of exercises of diferent formats:
word search, matching, interactive text, puzzle solving, audio and video tasks. In such way,
the systematic and anchoring functions are realized. Fragments of diferent types of training
exercises are given in figures 7-9.</p>
      <p>The functionality of the developed multimedia tutorial also includes the arrangement of
cognitive activities, including game activity. That means that a trainee is able to work at
their own pace, both independently and under the guidance of the teacher. In addition, all
of the tasks ofered to the student can be performed several times to achieve the best results.
In order to increase motivation for learning, the tutorial involves pupils into game activities.
It ofers quizzes, crossword puzzles, cognitive grammar trips, quests etc (figure 10). These
kinds of activity provided by the tutorial ensure fulfillment of the developing, systematic and
consolidation functions (from the first, second and third groups).</p>
      <p>The tutorial expects technological capability of its uploading to other websites and be
integrated easily with other electronic sources and environments (figure 11), which facilitates the
implementation of integrating and coordinating functions. It is also essential that the tutorial
works correctly with all browsers like Google Chrome, Microsoft Edge, Opera, Mozila Firefox.</p>
      <p>In addition, the tutorial has the functionality, which helps students to communicate with their
teacher. For example, comments element can be used to ask questions, to do the exercise, send a
speech to a teacher, or ask for help from other trainees. In such a way, the tutorial implements
the didactic feedback function.</p>
      <p>Thus, the analysis of the developed multimedia tutorial (provided by the students on the
ifnal stage of the project) testifies that the tutorial designed on the basis of functional approach
becomes really innovative, as it creates for a trainee the integral cloud-based cognitive
environment oriented on the activity-centred learning. In fact, the tutorial provides pupils with a
platform for their independent cognitive activity, for their motivation to learning due to
availability of tasks choice and ways of their fulfilling. As a result, it promotes cohesive development
of both of students and their potential pupils.</p>
      <p>The other example of functional approach applying to the design of innovative digital learning
aids is the development of the e-guide on the cryptography fundamentals provided by
preservice IT specialists (unlike the first e-tutorial realized within vocational training of pre-service
teachers of Computer Science and English), but also within their project-oriented activity in
the process of their holistic training. Including this example, we also aimed to demonstrate
main features of the approach realization on the samples of e-guides for completely diferent
target audience (schoolchildren and university students), knowledge domain, forms of potential
students’ activities etc.</p>
      <p>At the first stage of the project activity, the didactic functions and structure of the e-guide
were determined due to problems of the course “Information security”, which is a basic one for
lots of vocations.</p>
      <p>
        In such a way, resting on the theoretical background on the functional approach (covered
above), the students defined proper structural components of the learning aid. In particular, it
was determined that the e-guide must contain the textual component organized in hypertext
form which presents systematized and didactically processed learning material according to
the syllabus of the academic discipline. Here the place of the cryptography fundamentals in
the course was determined, and the necessity of coverage in the aid of encryption as one of
the means of information protection was established. The learning material was selected and
structured on the basis of a number of sources on the basics of cryptography and modern
computer encryption systems [
        <xref ref-type="bibr" rid="ref34 ref35 ref36 ref37">34, 35, 36, 37</xref>
        ].
      </p>
      <p>It was also determined that the textual component has to provide transition to non-textual
structural components: Illustrative material and Apparatus of the acquisition arrangement.</p>
      <p>Illustrative material should contain the static illustrations (technical charts, schemes, photos,
pictures etc.) and dynamic ones (animated or video illustrations that demonstrate diferent
methods of information encrypting).</p>
      <p>Apparatus of the acquisition arrangement should be represented by a library of learning
tasks of diferent types and a system of self-checking. Among the learning tasks of the e-guide
should be distinguished three basic types of the tasks: teaching, training and cognitive-search
ones.</p>
      <p>At the next stage of the students’ project-oriented activity, the e-guide whose functions and
structure were specified at the previous stage was developed in the environment of MS Learning
Content Development System using its tools and facilities. The developed learning aid covers
the following topics on the basics of cryptography: “Basic concepts of information security”,
“Cryptology as a science”, “Classical encryption algorithms”, “Computer encryption systems”.</p>
      <p>As it was planned, the e-guide contains a textual component organized in the form of
hypertext, which allows to find quickly necessary learning material on the course, navigate
easily the topics and sections, work with illustrations and tasks, refer to external links for other
information resources (figure 12).</p>
      <p>The textual component is supported by the Illustrative material component which provides
a trainee with two types of illustrations. The first type includes static illustrations, such as
generalized schemes of computer cryptosystems, the visualization of which facilitates the
understanding of educational content (figure 13), contributes to the transformational didactic
function and function of visual method use.</p>
      <p>The second type of illustrations are dynamic ones which demonstrate the process of data
encrypting based on various encryption algorithms; processes that reproduce the sequence of
actions in the operation of encryption algorithms, historical information, the essence of some
abstract concepts, and so on. This component gives for potentical trainees the opportunity
to observe these processes, review them at diferent speeds and check the assimilation of the
content, answering a number of questions to the reviewed dynamic illustrations ofered by the
e-guide.</p>
      <p>Thus, the work provided by the e-guide with its hypertextual component supported by static
and dynamic illustrations promotes implementation of informational, transformational and
systematizing functions (the second group of functions depicted in the Theoretical framework
above).</p>
      <p>Apparatus of the acquisition arrangement of the e-guide, as it was planned, is represented by
a library of learning tasks of diferent types that are forcused on the mastering of theoretical
content, and a system of self-checking.</p>
      <p>The teaching tasks of the developed aid are ready-made programs (realized in diferent
programming environments) that implement a certain encryption algorithm. The e-guide
encourages a trainee to work with the program, to find out its purpose and functions, and to
analyze the program code. In particular, the teaching tasks allow data encrypting and decrypting
based on some classic encryption algorithms. The solution of the teaching task expects trainee’s
processing, according to a certain scheme proposed by the library of teaching tasks (or by
the teacher). Trainees have the opportunity to run them, analyze the operation of algorithms
and make conclusions by answering questions. In addition, it is possible to copy fragments of
program code and use them to develop trainees’own programs (figures 14-15).</p>
      <p>Training tasks include tasks similar to teaching ones, but students solve them independently,
based on theoretical content and program implementation of teaching tasks. For example,
working with the code of the learning task, a trainee masters the encryption of a certain
algorithm, and then he is ofered a training task to implement a decryption program by the
same algorithm. Some of the training tasks are focused on working out the skills of using
various encryption algorithms via the set of exercises. For example, for the topic “Replacement
encryptions” and “Substitution encryptions”, the e-guide ofers the set of exercises given at the
ifgures 16-17.</p>
      <p>Cognitive-search tasks presented by the Apparatus of the acquisition arrangement are aimed
at applying knowledge at the creative level. Trainees are ofered a number of tasks on each
topic: tasks that require significantly transformed knowledge; tasks for independent application
of diferent types of encryption algorithms; research tasks and comparative analysis of diferent
information encryption systems; complex tasks on the composition and those that involve
gradual complication etc. Each task has instructions and answer, as well as the references to
relevant theoretical material or to the teaching tasks of the manual.</p>
      <p>Thus, the developed and filled library of the learning tasks allows to realize at a higher level
the functions of consolidation (the second group of functions) and development (the fourth
group of functions).</p>
      <p>The self-checking system presented in the e-guide is realized with the help of Google Forms
(figure 18). The system includes a set of generalized test tasks to check the level of mastery
of educational material. The form is connected to the Google spreadsheet and the answers
of the respondents are automatically stored in it, which in turn allows the teacher to analyze
the trainees’achievements. Thus, the implemented system of self-checking contributes to the
implementation of such didactic functions as the functions of correction and control (the third
group of functions), consolidation (the second group), and developing and educational function
(the fourth group).</p>
      <p>Thus, the digital learning aid, designed by the students based on the functional approach,
makes a whole learning environment suitable for use in the educational process of IT specialists
training within the course “Information Security” providing its holistic learning.</p>
      <p>At the final stage of the students’ project-oriented activity the developed e-guide was tested
and elaborated. In addition, there were ofered some methodical recommendations as for its
using at the educational process of the university in its diferent forms.</p>
      <p>Summing up the depicted experience and specific examples, we would emphasize the
following. The functional approach which was applied by the students to the design of the digital
learning aids demonstrated its great benefits as for the quality of the aids as the results of the
students’project-oriented activity. In particular, the functional approach enabled the students
(1) to specify the goals of development; (2) to determine the aid’s structure components, their
purposes, and their mutual connections; (3) to clarify the choice of the fulcrums for the purposes
achievement; to control the process of the aid development; (4) to provide objective estimation
of the results; (5) to promote the demand and practical application of the created digital learning
aid. Here, it is important to point out that the result of the academic project-oriented activity
had not only learning value, but also obtained essential practical application. Th elaborated
digital learning aids were approved in the real educational processes at school and at university
during various kinds of practices. The results of the work were also presented during the
students conferences and workshops.</p>
      <p>It is also worth underlying, that on condition of such an interdisciplinary preparation and
project activity, pre-service IT specialists obtain meta-skills on the design of innovative digital
learning aids. In the process of this kind of training, potential pre-service IT specialists obtain
full understanding and capability for practical embodiment of core ideas of holistic educational
approach via their personal experience of development of the learning aids. In addition, the
application of the fuctional approach made students’ project activity more practically driven
and motivational.</p>
      <p>It seems to be reasonable to predict positive influence of this kind of training on the forming
of the students’ holistic system of professional knowledge and skills. Elaboration of proper
methodology of its diagnosing and estimation is a prospect of our further research.</p>

      <title>4. Conclusions</title>
      <p>This paper presents the practical aspects and outcomes of applying the functional approach to
the development of contemporary digital learning aids in the process of project-based activity
of pre-service IT specialists within their holistic vocational training. The paper draws on the
theoretical framework of holistic education and the functional principles of digital didactic aids
design. The paper illustrates two specific examples of students’ project work on creating digital
learning aids using the functional approach: (1) a multimedia tutorial for teaching English
to schoolchildren (done by pre-service teachers of Computer Science and English) and (2) an
e-guide on the basics of cryptography for university students (done by pre-service IT specialists).
The paper analyzes the benefits and advantages of such project work from the perspective of
holistic and functional approaches. The paper also suggests some directions for future research
in this area.</p>
