       Abstract. An important component of the general aim of secondary education is
       the formation of a scientific worldview of the youth; it is based on empirical and
       theoretical knowledge about the world as a whole. The most fundamental laws
       and principles of nature compose a comprehensive physics picture of the world.
       An important part of formation of the picture in the pupils’ minds is experimental
       verification of the fundamental laws of nature.
           The analysis of a significant number of currently available in the domestic
       market physics-based software products has shown that they are presented in the
       form of electronic tutorials, electronic libraries, and various virtual physics la-
       boratories designed to study models of physics processes or phenomena.
           The authors prove the definition of virtual educational physics experiment
       (VEPE) as a kind of educational physics experiment that is carried out using dig-
       ital models of phenomena and processes, multimedia, interactive animations, and
       simulations. In accordance with the didactic aim, the VEPE is divided into
       demonstration and laboratory.
           Application of the VEPE during the study of molecular physics shows the
       suitability of its using for a new material explaining, the knowledge updating,
       and determination of the degree of formation of the pupils’ subject competence.
           The conclusion about necessity of the search of optimal forms and methods
       for integrating real and virtual experiments is made by the authors; the integration
       will promote both the visibility and accessibility of material perception and the
       development of the pupils’ creative abilities and various forms of thinking.

       Keywords: virtual educational physics experiment, scientific picture of the
       world, virtual physics laboratory, interactive model, physics simulation.


1      Introduction

Problem statement. The General Provisions of the Law of Ukraine «On Education»
state that one of the fundamentals of state policy in the field of education is its scientific
character [1], the key component of the aim of secondary education is the formation of
ideological orientations of pupils [6], [27].
    The concept of the worldview is a general scientific category; it is defined in aca-
demic dictionaries as «a particular philosophy of life or conception of the world» [8],
«the system of standpoints on the objective world and the place of man in it» [7], «a
comprehensive conception or apprehension of the world especially from a specific
standpoint» [28], and «is based on experimental and theoretical knowledge about the
world as a whole, which is characterized by objectivity, verity, general significance,
purposefulness, reproducibility, determinism, necessity, efficiency of changes in the
natural-historical reality» [19].
    The scientific worldview mainly concerns the modeling of the world and should
provide a scientific explanation of general philosophical questions ( 1) what is? ontol-
ogy (model of reality as a whole); 2) where does it all come from? explanation (model
of the past); 3) where are we going? prediction (model of the future); 4) what is good
and what is evil? axiology (theory of values); 5) how should we act? praxeology (theory
of actions); 6) what is true and what is false? epistemology (theory of knowledge)); the
worldview is founded and verified by observations and experiments [32, p. 8].
    The basis of the scientific worldview is the scientific picture of the world (SPW); it
is an integral system of representation of general properties and rules of nature, conse-
quence of the synthesis of basic natural scientific concepts and principles [19, p. 326 –
327]. Its structure consists of the conceptual and sensory-imaged components. The con-
ceptual component of the SPW includes philosophical categories (matter, motion,
space, time, etc.), principles (material unity of the world, determinism, etc.), general
scientific concepts and laws (for example, the law of conservation and transformation
of energy) as well as fundamental concepts of individual sciences (field, substance,
universe, population, etc.). Explanation of the basic laws and properties of nature in the
SPW is carried out through visual images. They form the sensory-imaged component
of the SPW that is a set of visual representations of certain objects and their properties
(for example, a planetary model of an atom, an expanding model of the Universe, etc.)
[25, p. 37].
    Fundamental science that studies the general laws that describes regularity of phe-
nomena in the material world, creates basis of the world understanding at different lev-
els of knowledge about the nature, and provides a general justification of the scientific
picture of the world is physics; the physics picture of the world combines the most
fundamental laws and principles of nature [14, p. 3-5, 6]. Therefore, it is physics that is
positioned in the rank of universal scientific picture of the world in the history and
philosophy of science and technology of the twentieth century [25].
    Physics is an experimental science. Therefore, an important part of the formation of
the physics picture of the world is the study and implementation of physics experiments,
which are carried out by means of demonstrations and laboratory experiments during
traditional forms of learning [2, 3]. However, it is impossible to reproduce most of the
fundamental experiments in the classroom due to the complex equipment or methodol-
ogy, the interval of time, the non-compliance with safety standards, impossibility of
creating experimental conditions in educational institutions etc.
    An important instrument of physics as a science is to simplify the consideration of
real complex objects by presenting them in the form of models. It creates the conditions
for solving the methodical problems by implementation of a virtual physics experiment
in the educational process. Computer programs allow to simulate the physics process
as well as to change the conditions and parameters of its performance [16]. The math-
ematical basis of the virtual model enables the obtaining of idealized values of physics
quantities and creates opportunities for the laws checking and identifying rules in the
«pure form» without any errors during the natural experiment.
    Obviously, such a software product is sensitive to changes of all types of information
technology (network, cloud, multimedia). The above-mentioned reveals significant op-
portunities for involving all participants of the educational process in the «vertical-hor-
izontal» educational interaction; the work can be carried out in the classroom and / or
using remote access, individually and / or in the group, independently and / or under
the supervision of the teacher depending on the type of educational physics experiment,
its aims, tasks, forms, and methods of study [13].
    The conducted research has shown that the virtual physics experiments are widely
used in the educational process of secondary and higher schools but the theoretical basis
and didactic approaches to their use as a means of forming of the scientific picture of
the world in the subjects of study is a poorly studied pedagogical problem.


Analysis of recent studies and publications. An analysis of literary sources has shown
that certain unrelated theoretical and practical aspects of this problem are revealed in a
large number of scientific publications of domestic and foreign scientists at the end of
the XX – early XXI century. The results of research on the problems of formation of
the scientific worldview and the scientific picture of the world are presented in the
works of William W. Cobern, Michael R. Matthews, Hugh G. Gauch Jr., M. Ginzburg,
S. Goncharenko. Simulation of the virtual physics experiment was considered by M.
Golovko, Yu. Zhuk. The influence of the virtual experiment on the attitude of students
to physics was studied by A. Alexiou, Z. Ayoubi, E. Bozkurt, C. Bouras, E. Giannaka,
M. Faour. Application of virtual physics experiment in education was considered by
J. Mirçik, A. Saka, J. Singh, Ya-feng LI, Z. Zacharia. Integration of a real and virtual
educational physics experiment was studied by S. Velichko, I. Salnik, I. Slipukhina.
Preparation of the physics teachers for use of the virtual physics experiment in class-
room was revealed by V. Charko. Didactic principles and programs for video analysis
of physics phenomena were studied by J. Chernetsky.
   It was found that the following directions of the use of virtual physics experiment as
the demonstration of physics experimentations, phenomena, structure, and properties
of real and artificial (technical) objects as well as various simulations have the most
recognition in the methodology of physics education at present [18, 33].
   According to V. D. Sharko, a virtual physics experiment in the physics teaching can
work as a means of cognition, the provision of components of «ready» knowledge, the
visual aids; depending on the pedagogical purpose, it accompanies to other ways of the
«ready» knowledge presenting, acts as a simulator for the individual cognitive abilities
processing, means of testing the level of formation of knowledge and skills of pupils
[24].
   The research has exposed that a number of software packages intended for conduct-
ing of virtual educational experiments is presented now in the market of Ukraine. It has
been found out that there are almost 40 such softwares for physics study that are created
and used in the educational process (Table 1).

The analysis has showed that existing educational softwares for physics are presented
as electronic tutorials, electronic visualization libraries, and virtual sciences laborato-
ries. Thus, the virtual physics laboratory is a software tool designed to simulate pupils’
work in a real physics laboratory during the study of physics processes or phenomena
[12].
   As can be seen from Table 1, only the «Kvazar – Micro Tech», «Kontur Plus»,
«Transportation systems», and «Rozumniki» softwares have the «Virtual Physics La-
boratory» complex. Such software makes it possible to perform a laboratory work using
an imitation model of a physics phenomenon or process, independently select equip-
ment for laboratory work, and change the input parameters of the experiment.
   However, despite the popularity among teachers, virtual laboratories that are part of
the software have certain disadvantages [5]. Only a small amount of them is intended
for use during an educational physics experiment. At the same time, almost all such
softwares do not use video clips and video observations of natural observations, real
experiments are replaced by animations (in many cases of poor quality) or computer
models [23]. In this context, as shown in the works of I. S. Chernetsky, special attention
is deserved for a program Video Analysis Tracker, which is freely available on the
network and allows to explore real processes and build their mathematical models based
on video analysis [4].
   On the other hand, domestic and foreign markets propose software products that al-
most completely satisfy the requirements of users both in terms of structure and func-
tionality. These products include virtual on-line labs. They allow you to conduct exper-
iments without buying additional programs. For example, the purpose of the «Physics
Education Technology» package [21] is to interactively simulate physics phenomena
for their demonstration during the educational process.
   This resource represents virtual laboratories that can display various natural phe-
nomena as well as interactive mathematical tools. Virtual labs contain one or more tasks
as well as a set of the elements needed to solve them. The main purpose of the demon-
strations is visualization and explanation of the phenomena but not testing the
knowledge and skills of the user. The search for virtual labs in this portal can take place
via the subject, via the level of education (primary, secondary, high school, and higher
education), via devices (computer, tablet), and via interface translations.
   «VirtuLab» (http://www.virtulab.net/) is one of the largest collections of virtual ex-
periments in various disciplines. The main unit of this portal collection is a virtual ex-
periment. Each video segment allows pupils to conduct an experiment that has an edu-
cational purpose and a clear task. All the tools and objects needed to get the result are
offered to the user.
   Interactive simulations for primary and high school pupils are provided on «Gizmos»
[11]. This portal contains over 400 simulations that can be hosted in your own virtual
classroom.
   The domestic product Steam- laboratory deserves particular attention «MANLab»
(https://stemua.sciens). It is the center of real and virtual study research aimed at sup-
porting and developing STEM-education in Ukraine. This laboratory specializes in con-
ducting research in the field of natural sciences: physics, chemistry, biology, geogra-
phy, astronomy, ecology, mineralogy. Information and technology components are the
educational programs, methodical materials, virtual laboratories. The site is Ukrainian-
language. Its resource filling is constantly updated. A user can see in detail the digital
equipment needed for a real experiment and its digitization. The video section contains
lectures and experiments on the main topics of physics that are convenient for use in
the stages of explaining the new material.
   Several hundred animations from all sections of the school physics course are col-
lected on the site «Physical bag» (http://fizikasoloosh.blogspot.com/p/blog-
page_39.html). However, you need to download to your computer and have a file player
with the extension * swf. in order to play them.
   At the same time, on-line softwares that do not require additional software such as
«Fowler's Physics Applets» are more popular among consumers [10].
   We need to mention The «Electronic Workbench» software (https://softfa-
mous.com/lucid-electronics-workbench/), which is intended for simulation of digital
and analogue electronic circuits and includes editing tools, simulations, circuit testing
tools, and additional tools for analyzing models. Similar on-line features are provided
by the «Circuitlab» software (https://www.circuitlab.com/editor/#?id=7pq5wm).
   The «Interactive Physics 2000» computer educational environment
(https://www.design-simulation.com/IP/simulations.php) is designed to create two-di-
mensional mechanical models. Models are created without programming by the com-
puter mouse. Emulations of the mechanics of particles, springs, solids deformations,
gravitational and Coulomb forces are possible with the help of Interactive Physics 2000.
   Thus, virtual physics labs software tools and resources with the ability to conduct
physics experiments are presented in large numbers in free access. The mentioned ped-
agogical possibilities are amplified by the high technology of modern software prod-
ucts, in particular, the possibility of their use on various gadgets in the «24/7» mode
[26]. That obviously has positive effect to the educational interest and the desire of
pupils to explore physics phenomena and processes independently turning virtual phys-
ics experiment into a valuable didactic means for forming the physics picture of the
world.
   However, the theory and methods of using a virtual physics experiment as a means
of forming the scientific picture of the world in the subjects of education are little-
studied pedagogical problem today.


   The purpose of the article is to specify the content of the category of virtual edu-
cational physics experiment and to highlight its significance in forming the components
of the scientific picture of the world for pupils.


2      The Results and Discussion

The term «Virtual Educational Physics Experiment» (VEPE) has not a well-defined
meaning yet. The variety of definitions makes pay attention to the sense of this concept.
It is composed of two main attributes: general: «educational physics experiment» and
specific: «virtual».
    In general, the experiment is considered as a method of scientific knowledge, a
method of sensory-objective activity in science through which phenomena are studied
in appropriately selected or artificially created conditions that can show the flow of
processes in a clear form. Such observation is necessary to establish regular relation-
ships between phenomena. [19, р. 117–118]. On the other hand, the experiment is made
to demonstrate a known reality, examine the validity of a hypothesis, or determine the
efficiency of something previously untried [29]. In the school course of physics, the
experiment is considered as: a reflection of the scientific method of research in physics
[17]; way of reproducing of physics phenomena with the help of special devices during
lessons or extracurricular activities [6]. In this regard, the educational physics experi-
ment acts as an organic component of the methodological system of learning, which
ensures the formation of the necessary practical and research skills, personal experience
of experimental activity of the pupils. It is the most important method and specific
means of scientific knowledge.
    The results of the research [23, 34] indicate that the physics experiment can be im-
plemented in the following areas: 1) an independent form of a real experiment with
subsequent programmed elaboration of its results (interaction «pupil – object»); 2) a
natural study in conjunction with the use of digital complexes and computers (interac-
tion «pupil – a digital measuring complex – an object»); 3) virtual experiment (interac-
tion «pupil – model»). The first approach is appropriate in the case when the experiment
is not limited by the capabilities of existing laboratory equipment. The second and third
approaches allow to significantly expand the topic and quality of experimental research
as well as to obtain more accurate results.
    Continuing the clarification of the definition of VEPE, we turn to its specific feature
«virtual» (from the Latin «virtualis» – possible, one that does not have physics embod-
iment [19], «not physically existing as such but made by software to appear to do
so,…carried out, accessed, or stored by means of a computer, especially over a net-
work» [8]. Thus, a virtual experiment is called a computer experiment, which consists
of simulation of phenomena, objects, research tools, and actions that a user must con-
duct in a real laboratory.
    In the context of our study, we recognize the VEPE as a kind of educational physics
experiment that serves as a means of physics processes and phenomena demonstrating
or simulating with the help of a computer.
    In accordance with the didactic aim and by analogy with the real physics experiment,
the VEPE is divided into demonstration experiment and laboratory one (Fig. 1).

Considering the VEPE as a didactic object, it should be noted that it is a method, form
and means of study: the subjects of the study perform certain practical tasks (experi-
ments) operating by the virtual images of physics objects, phenomena and research
equipment that reproduce the appearance and functions of real objects. The VEPE is
aimed at achieving the same didactic aims as the corresponding real physics experi-
ment; it facilitates the formation of research skills using the devices and equipment of
the modern physics laboratory as well as stimulates the interest of pupils as a technical
and technological object.
   Note that the use of VEPE is the best or the only possible way of study in a lot of
situations: this is distance learning, the lack of the ability to conduct a real experiment
(inaccessibility or complexity of equipment, time constraints). In addition, VEPE can
be used for preparation of a full-scale experiment: to develop the necessary skills for
studying the actual process (for example, studying isoprocesses, reviewing the thermal
balance under conditions of mixing water of different temperatures, determining the
focal length and optical force of a thin lens), to predict possible mistakes in the prepa-
ration and the conduct of the experiment (for example, the construction and research of
the electric circuit, the construction and testing of the electromagnet), the methods of
complex equipment handling (studying the structure and action of complicated optical
devices, an eye model, the principle of the ion particles counter), observation of con-
tinuous and line substances spectra, observation of tracks of particles in a cloud cham-
ber).
   The VEPE in the educational process may be part of the laboratory work that is based
on a virtual physics laboratory that simulates the main stages of the laboratory work
and contains methodological instructions with theoretical information, tasks, techno-
logical map, and requirements for the report.
   In order to determine the level of use of the virtual educational experiment in the
educational process, an Internet survey of physics teachers of Kherson and Kherson
region was conducted. The results of the survey are presented in the diagram (Fig. 2).

                   Fig. 2. The use of virtual software by physics teachers

The analysis of the teachers’ answers affirms the low level of use of virtual technologies
during physics study. The teachers give preference to virtual labs and a demonstration
experiment; they practically do not use a virtual experiment at the stages of knowledge
learning or at homework. The most complete and demanded products among the virtual
means are: software tools of production «Kvazar – Micro Tech»; available on-line vir-
tual laboratory works «Physics Education Technology», «VirtuLab», «Getaclass»; mo-
bile tutorials (Toolbox Sensor Suite, Lab4Physics) (Fig. 3).

           Fig. 3. The most demanded virtual software among teachers of physics
It should be noted that the high-quality VEPE must satisfy such requirements [9, 12,
24]:
─ evident similarities with real physics devices and their real behavior in time and
  space;
─ the course of the work and the results processing must not differ from the real ex-
  periment;
─ in virtual labs as in real experiment, pupils should be faced with transient processes,
  the need for temporary exposure before the results obtaining;
─ models should provide the possibility of random errors.

   Taking into account the aforementioned, we give examples of the use of the VEPE
in the educational process during Molecular physics study. Let us denote that the fun-
damental of molecular physics is the experiments of J. Perrin, O. Stern, R. Boyle, E.
Mariotta, J. Charles, J. Gay-Lussac.
   At the stage of actualization of the knowledge or when explaining new material,
teachers often use demonstration fragmentary video. Thus, ManLab has selected in the
educational environment four video experiments on the topic «Isoprocesses in gases»:
demonstration of the experiment «Egg in a bottle», demonstration of the isobaric pro-
cess, demonstration of gas isochoric heating, and demonstration of isothermal gas ex-
pansion (Fig. 4). Each process is accompanied by a graphical model [15].
   The method of conducting the experiment «Isothermal expansion of gas» is not com-
plicated; therefore, it can be performed at a lesson. However, if it is not possible, the
video experiment can be offered to pupils as homework.

When studying the basic laws of the molecular-kinetic theory and their experimental
verification, pupils are invited to observe the Brownian motion of a paint particle in
water using the school microscope. However, school measuring instruments practically
cannot display the trajectory of the particle motion or the path it traverses. However, if
we take the Fowler's Physics Applets online resource animation [10], it gives an oppor-
tunity not only to show the trajectory of the particle but to change the amount of the
substance particles and to investigate the change in the nature of the motion of a Brown-
ian particle (Fig. 5).

Using the model of particles motion at a certain temperature that is accessible on the
resource «Gizmos» [11], pupils can explore the form of Maxwell's distribution of mol-
ecules by speeds for different gases and establish the dependence of the mean square
speed of molecules on the temperature (Fig. 6). When studying the distribution func-
tion, the teacher can propose to pupils to establish a mathematical relationship between
the values in this animation and verify the reliability of the established dependence by
calculations of the speed numerical value. The task should be arranged in the form of a
physics problem; the values necessary for calculation can be taken from the model con-
dition.

An essential element of the physics study is the laboratory works carrying out. The
physics program for class 10 during the study of the topic «Molecular Physics and
Thermodynamics» offers for the performance three laboratory works: one of the iso-
processes study; determination of the coefficient of surface tension of the liquid; deter-
mination the modulus of elasticity of various substances. Most of the proposed works
fulfilment in real conditions is very difficult. The use of virtual laboratories can be a
solution of this problem. Thus, the virtual laboratory work «Examination of the law of
Gay-Lussac» can be performed using the software on the portal «Physics. Virtual La-
boratory – 2» [22]. Note that the order of the actions during this virtual experiment
coincides with the real one, which makes it possible to compare the obtained results
(real and virtual). The purpose of this work is to observe the isobar process and verify
the validity of the law of Gay-Lussac. The right part of the window shows the equip-
ment necessary for the work: a glass tube, a cylindrical vessel (on the left), a glass of
water at room temperature (on the right), plasticine, a thermometer, a ruler, an alcohol
lamp. The thermometer in the initial position shows the ambient temperature. All de-
vices are used in turn, using the «click» of the left button of the computer mouse.
   Calculations of the experiment results including absolute and relative errors are car-
ried out using the calculator located on the right side of the screen; they are entered into
the table located at the bottom of the web page. At the end of the lab, pupils are asked
to give answers to control questions.
   The use of virtual simulations at the stage of knowledge control allows the teacher
to determine the degree of the formation of pupil competence more exactly. For exam-
ple, when studying an important fundamental notion of «intermolecular interaction»,
pupils can be invited to perform a test task using the simulation «Basic principles of
Molecular-Kinetic theory » of Physics Education Technology (Fig. 7) [21].

Pupils are offered to work with the simulation and answer the test questions. It is pos-
sible to pass the test both on a printed form and in an interactive mode using the «Learn-
ingApps» (https://learningapps.org/), «Kahhot!» (https://kahoot.com/), «Online Test
Pad» (https://onlinetestpad.com/ua), «Master test» (http://master-test.net/).
   Of course, a virtual experiment cannot completely replace the real one; however, the
results of our research indicate that the virtual experiment allows:

─ to show clearly many physics phenomena and certain experiments that cannot be
  reproduced in real life;
─ to demonstrate those subtleties of the process, which are invisible when performing
  laboratory work in real life;
─ to highlight the main thing and to remove the secondary factors of influence during
  the experiment;
─ to establish certain regularities of occurrence of phenomena in special conditions,
  which cannot be created in reality;
─ to repeat the research many times with varying parameters;
─ to change in the wide range the initial parameters and conditions of the research;
─ to simulate situations impossible in real conditions, etc.


3      Conclusions and Prospects for Further Research

Summarizing the abovementioned, we can say that the formation of a scientific picture
of the world for pupils is a complex process of perception of the original philosophical
ideas and principles of science, understanding of the basic theories, the mastering of
fundamental concepts, and the ability to apply research methods during further educa-
tion. An important role in the process is played by natural sciences; physics takes the
main place among them.
   The definition of virtual educational physics experiment as a kind of educational
physics experiment acting as a means of demonstration or simulation of physics pro-
cesses and phenomena with the help of a computer is substantiated in the research.
Didactic importance of VEPE is the following: it is simultaneously a method, a form,
and a means of study. It is shown that the use of mathematical models of phenomena
and processes is particularly important in the process of formation of initial compe-
tences in physics at the level of understanding of fundamental laws, phenomena, and
processes in the material world.
   The peculiarities of methodology of usage of video clips (updating of knowledge,
explanation of new material, independent work of pupils), virtual animations (demon-
stration of complex experiments), interactive models (establishing a direct connection
between the physics phenomenon and the law), virtual laboratory works (fulfilment of
learning research) are considered on the example of VEPE application during the study
of molecular physics. The elements of the method of usage of virtual simulations with
test questions for determination of the degree of formation of pupils' subject compe-
tence are worked out.
   It is shown that VEPE has powerful didactic capabilities as a means of constructing
the world scientific picture at the level of awareness of physics and general scientific
concepts, principles, and laws. It is concluded that its special function is the formation
of the sensory-imaged component of the scientific worldview for development of im-
agination of physics objects and their properties by visualization of the model of a real
phenomenon. Such a feature of the VEPE is significant at the initial stage of the for-
mation of elements of the scientific worldview.
   Note that the features of VEPE as an educational tool, in particular, for the action
with idealized images, determines its interconnected use with a real physics experiment
where external influences and perturbing factors can be detected that lead to a «distor-
tion» of the theory. This approach will form critical thinking and research skills during
solving real problems of the surrounding world. Therefore, the search for innovative
approaches to the integration of VEPE and real-life research, which will promote both
the visibility and accessibility of material perception, as well as the development of
creative abilities and various forms of thinking, remains relevant. An important role in
the construction of appropriate methodological systems belongs to the synergetic ap-
proach.
