      <p>Since augmented reality technology already has an important place in innovative
development, it can also have significant potential for implementation in Mathematics
learning. That is why this technology needs more detailed study. Because augmented
reality is intrinsically linked to 3D construction, its usage in conjunction with
Dynamic Mathematics systems like GeoGebra, can significantly increase the level of
visualization in Mathematics and enhance students learning. In addition, Augmented
Reality can become a tool for enhancing STEM-based learning for students majoring
in Mathematics and Computer Science.</p>
      <p>At present, the use of augmented reality technology in teaching, including
Mathematics, requires development, research, and testing. Therefore, the review of
tools for developing augmented reality and current practices is relevant. It is
important the new technologies usage contribute to improving the quality of
education.

        A number of works of scientists and software developers are devoted to the research
of integration issues of the augmented reality technology into the educational process.

of the augmented reality application in education. Pavlo P. Nechypurenko [23; 24]
shares her experience of using AR in teaching chemistry pupils and future chemistry
teachers. Svitlana L. Malchenko raises the issue of the AR application to the
astronomy teaching and others [

        The problems of STEM-training, in particular the training of staff for
STEMeducation in the modern innovative educational and research environment are covered
by Mariya P. Shyshkina. The aim of the article [
        <xref ref-type="bibr" rid="ref31">31</xref>
        ] is to describe the problems of
personnel training that arise in view of extension of the STEM approach to education,
development of innovative technologies, in particular, virtualization, augmented
reality, the use of ICT outsourcing in educational systems design. The results of the
research are the next: the concepts and the model of the cloud-based environment of
STEM education is substantiated, the problems of personnel training at the present
stage are outlined. Recently in the field of STEM education the following ICT trends
have been developed, such as new interfaces, screenless displays, 3D technologies,
augmented reality, “emotional” computing, wearable technologies (devices) and
others. All these areas are united under the common name of “new opportunities”
(emerging technologies) [
        <xref ref-type="bibr" rid="ref31">31</xref>
        ].
      </p>
      <p>Having analyzed the state of research into the problem of STEM-education in the
secondary education institutions in psycho-pedagogical, methodical and educational
literature, we can conclude that in Ukraine the educational landscape is aimed at the
innovative student. Teaching a student to learn for life, to think critically, to set goals
and achieve them, to work in a team, to communicate in a multicultural environment
all this is the urgency of the present, which forms the basis of a specialist's
competitiveness in the labour market.</p>
      <p>
        The issues of using GeoGebra were highlighted by us in a teaching manual
designed to train mathematics teachers in higher education institutions [
        <xref ref-type="bibr" rid="ref12">12</xref>
        ]. The
methodological recommendations were presented there, which teach how to create
and apply for the tool of different topics in elementary mathematics. The visuals are
hosted in a file repository GeoGebra. They can be accessed either via traditional links
or via QR codes.

          ] discusses the prospects of the augmented reality using as a component
of a cloud-based environment. It is revealed that the attraction of the augmented
reality for the educators requires the development of new methodologies, didactic
materials, updating and updating of the curriculum. The main conclusions and
recommendations: the main principles of augmented reality use in the learning
process are: designing of the environment that is flexible enough, attention should be
paid to the teaching and didactic issues; adjusting the educational content for
mastering the material provided by the curriculum; the research methods that can be
used in training along with the elements of augmented reality are to be elaborated;
development of adaptive materials; training of teachers, which will include
augmented reality in educational practice.

of the augmented reality technology use to meet the needs of modern society. The
peculiarities of the augmented reality realization as an innovative product that has
significant prospects for integration into the real economy are considered. The role of
this technology in improving the teaching subjects process in Ukraine’s higher
educational institutions is determined. The main directions of communication
intensification with students during conducting of classes with the help of using the
augmented reality are given. The key benefits for the national education system from
implementation of the augmented reality into the educational process are highlighted.

          ] Hong-Quan Le and Jee-In Kim propose a framework for learning
geometry using a software tool based on augmented reality (AR) and hand gestures
recognition technologies. These technologies are combined into a system that can
address some current issues in geometry education and provide students with an
easier way for studying geometry. They compare the speed of development and the
quality of the developed geometry training using Cabri and GeoGebra.
        </p>
        <p>The objective of research is to develop an AR and hand gesture based application
for learning 3D geometry. This paper aims to present a novel approach for effective
learning 3D geometry in school. The research basically focused on two main
technologies: AR and hand gesture recognition to build up a hands-on learning
method for students. With AR, the students can understand the basic concepts of 3D
geometrical shapes, their relationships and ways to construct the 3D shapes and the
objects in 3D space. Importantly, AR can provide a dynamic visualization of 3D
structures of geometrical shapes. This feature helps the students to understand a
comprehensive background of 3D geometrical shapes and improve the abilities of
geometrical structures. Moreover, the hand gesture based interactions furnish an
intuitive and convenient way for the students to directly control and interact with
geometrical shapes in 3D space. With the experiences of interacting with the 3D
shapes using their own hand gestures, the students can improve their own awareness
of the relationships of the 3D shapes and easily remember or retain the knowledge
about the 3D shapes.

          A number of examples that can be used in mathematics training are offered by the
developers of the GeoGebra Dynamic Mathematics system [
          <xref ref-type="bibr" rid="ref6">6</xref>

        </p>
        <p>
          GeoGebra is a free software, dynamic mathematics system for all levels of
education that integrates geometry, algebra, tables, graphs, statistics and calculations
in one easy-to-use package [
          <xref ref-type="bibr" rid="ref30">30</xref>
          ]. GeoGebra has become a leading provider of dynamic
mathematics programs used to support Science, Technology, Engineering and
Mathematics (STEM), education and innovation in teaching and learning worldwide.
        </p>
        <p>We can highlight the benefits of GeoGebra, such as free distribution; easy-to-use
interface with powerful functionality; availability in many languages, including
Ukrainian; a number of freeware developments, models, exercises, lessons and games
for math, as well as video tutorials and courses to help you use GeoGebra
applications.</p>
        <p>GeoGebra is a few free offline apps for iOS, Android, Windows, Mac,
Chromebook and Linux. Among these mobile phone applications there is the 3D
Graphics application (3D-feature graphs, surface, and 3D-geometry) that can be used
while developing the visuals with AR. Today, the app is only available to users of
gadgets on the iOS operating system. This program includes some examples of 3D
mathematical objects that can be placed, such as on a desktop, floor, or any other flat
surface. Today, the app is only available to users of gadgets on the iOS operating
system. This program includes some examples of 3D mathematical objects that can be
placed, such as on a desktop, floor, or any other flat surface. The fixed models will be
managed. They can be resized. Such visualization will allow you to see more
mathematics in the surrounding world.</p>
        <p>With AR you can build polyhedra, surfaces (Fig. 1), rotation bodies, visualize their
rotation, and show cross 3D sections.</p>
        <p>GeoGebra developers note that they created this application to explore the AR
potential for mathematics training and teaching. This is just the beginning for
GeoGebra AR. In the future, the application will be improved, supplemented with
new ideas for 3D models, which will allow to see and explore 3D mathematics in the
environment more.</p>
        <p>Let’s see what kind of manipulation can be done using the AR app. We can, for
example, write down the surface equations and examine the result, change individual
parameters, and observe changes in real time. We can also “scan” the objects around
us, get the appropriate models, and further explore them. Before researching we have
to place mathematical objects on any surface. Built and fixed models can be
“bypassed” from all sides, “look” in the middle, take screenshots of internal
structures.</p>
        <p>3D Graphics mode is designed to work with 3D objects. You can create objects
using Algebra or Tools tabs. In Algebra mode, we add objects using mathematical
functions, and in Tools mode, we use a toolbar that offers a large set of tools for
creating three-dimensional objects. In addition to the well-known tools: creating
points, segments, straight lines, angles and polygons – there are also specialized tools
for constructing bulk bodies such as: sphere, pyramid, prism, cone, cylinder. You can
build cross sections of volumetric figures and form a sweep.</p>
        <p>
          Tim Brzezinski closely uses the 3D Graphics AR application in his activities.
Based on his research, we can conclude that the using AR is a powerful tool for the
explore and formatively assess student constructions. Brzezinski offers some
developed GeoGebraBook, targeted at both teachers and students. His collections
provide ideas for lessons and various means by which math teachers can use
GeoGebra 3D Grapher with AR (iOS) to create dynamic, learner-centered learning
environments [
          <xref ref-type="bibr" rid="ref2">2</xref>
          ]. In the mathematics teaching it is advisable to use some of his works
[1; 3; 4].

Tsybulka [
          <xref ref-type="bibr" rid="ref8">8</xref>
          ] focused on the training and retraining of mathematics teachers, as well
as on extracurricular work with students. Because the training is based on examples
and models that can be attributed to the objects of mathematical art, this allowed the
authors to present GeoGebra as a powerful tool for realizing STEAM education. One
of the sections of the practicum is AR. The authors present the brief information about
the AR application and provide examples of its use.

AR with GeoGebra you can see that we are surrounded by mathematical objects,
shapes everywhere [14; 15; 16] we can explore them, walk around them, peek in, or
step inside a figure.

volume, we can determine the relationship between the volume of the real body and
the result that is offered by the software. In this case, the student must have the
apparatus to apply the properties of such bodies.</p>
        <p>Previously, we offered students a STEM approach in addition to the traditional
formula output when learning the topic of “Body volumes”. The approach was that
the students were asked to propose some hypothesis how the volumes of a prism and a
pyramid, a cylinder, and a cone correlate. For this purpose, made models of these
geometric bodies were used and poured dry matter from the cone into the cylinder,
from the prism into the pyramid.</p>

        <title>Perspectives of using AR application in teaching calculus and probability theory</title>
        <p>An analysis of the studies conducted to date indicates that the greatest effectiveness in
teaching elementary mathematics, calculus, probability theory is achieved through a
complex combination of traditional tools, forms and methods of teaching with
computer-oriented. For plotting functions, surfaces are quite convenient to use
software tools, including CoCalc, GeoGebra, Wolfram|Alpha [10; 19; 20; 26; 32].</p>
        <p>With GeoGebra we can construct a surface, examine it from different sides,
examine the change of values of a function at one of the fixed independent variables,
or at certain relationships between independent variables. Similar observations are
useful in the study of the function of many variables for continuity. However, we
cannot calculate extrema by symbolic transformations, although partial derivatives
can be calculated.</p>
        <p>With GeoGebra 3D Calculator and AR the visualization capabilities for solving the
types of tasks outlined above are greatly enhanced.</p>
        <p>Particularly effective can be the use of a 3D Calculator with AR when studying the
topic of “Multiple integrals” (Fig. 3). Students often have difficulty with constructing
bodies that are restricted to certain surfaces.</p>
        <p>Using AR, you can not only see the built body, but also “travel” inside. Today, the
construction of surfaces is available with the application. Often, students have
problems in calculating the boundary of the function of two variables, while
substantiating continuity.</p>
        <p>It is advisable to use the software tools for both the construction of surfaces and the
search for extrema of functions.</p>
        <p>Here is an example of a problem where, when investigating the function of many
variables, additional research is needed. An interesting example is the function</p>
        <p>= 1 − + . At point (0; 0) partial derivatives of the first order do not exist. To
investigate a function on extremum, we examine the increment of the function at this
point. As the gain is negative, we can conclude that the function acquires the
maximum value at this point.
In the teaching of probability theory, it is possible to visualize such concepts as the
probability distribution function and the probability distribution density function for a
two-dimensional continuous random variable. By constructing the respective planes,
it will be possible to demonstrate graphs of the probability density functions for each
of the components.</p>
        <p>For example, by plotting the probability distribution function by the formula, we
can consider the surface formed in more detail. Next, we cross the surface with the
planes x = const or y = const. We can view the graphs of the probability density
functions for each of the components of a two-dimensional continuous random
variable (see Fig. 4).

      <title>Conclusions and prospects for further researches</title>
      <p>Researches show that the GeoGebra AR should be used both in the profile teaching of
mathematics students, and in the train of future mathematics teachers of higher
mathematics, probability theory, calculus, analytical geometry.</p>
      <p>At the same time, one of the major problems today in using the GeoGebra 3D
Graphing Calculator with AR is that it is designed for iOS. Available mobile phones
with Android operating system have become widespread in Ukraine.
Investigating the possibilities of using GeoGebra in the learning calculus and
geometry, found out that engaging students to research using GeoGebra helps to
expand the range of educational tasks, including STEM problems. This allow to
achieve the high level of learning motivation and individualize the learning process.</p>
      <p>Implementation of applied aspect in teaching mathematics using GeoGebra 3D
Calculator with AR will help to solve one of the main problems of STEM education –
individualization. We can explore AR objects because this application brings 3D math
to the real world.</p>
      <p>Systematic using of GeoGebra 3D Calculator with AR can help to develop
students’ research skills, enhance their socialization opportunities through the
acquisition of ICT, which should lead to the systematic development of universal
STEM competencies.</p>
      <p>Having looked at a number of forms and methods and tried out some of them, we
found that the goal of every STEM teacher should be to motivate and involve students
into research activity. Then more varied and interesting the lessons will be, then more
students will admire the subject. Implementation of the STEM education in
mathematics teaching makes it possible to improve the quality of learning, which will
further enhance the students’ academic competences.</p>
      <p>We see the prospect of further research in the development and investigation of the
effectiveness of the use of AR-based tools in both elementary and higher
mathematics.</p>
