Virtual reality Technical education Chemical industry 

1 Introduction

Despite the high expectations associated with virtual reality (VR) technologies, there are still no breakthrough innovations in its use in education and obvious advantages compared to “traditional” computer technologies. Meanwhile, the use of VR in education allows solving a number of fundamentally new tasks. In particular, studying phenomena and processes in the micro and macrocosm, within complex technical and biological systems, presenting various physical, chemical, biological and social processes that occur at a very high or too low speed in a shape convenient for studying, and simulating situations of experience-led training. This makes it important to study what is a potential of the VR use in technical education.

2 Classification of VR Applications in Education

The use of VR applications in educational practice requires pedagogical interpretation of the attributes of VR and their impact on the cognitive, developmental and educational process.

VR applications in education divide into two types [1]: (1) non-immersive (without immersion), where the virtual world is presented on a computer screen; (2) immersive, which completely immerse users in the virtual world.

The conducted analysis made it possible to identify the following main areas of use of VR in training of specialists in technical universities: (1) the creation of virtual equipment, primarily for simulating emergencies; (2) providing remote access to real authentic technology devices.

Let us consider examples of the use of VR applications in the training of engineers at Kazan National Research Technological University.

3 Virtual “Computer Science” Textbook Simulator

The understanding of virtuality in a broad sense can be illustrated by electronic textbooks-simulators developed in virtual educational environment of KNITU for independent mastering of content by students. In Fig. 1, the home page of the textbook-simulator on Computer Science developed at the Department of Intelligent Systems and Information Resource Management is presented.

The textbook simulator includes the following modules: informational, which provides the possibility of wide variation of static parameters (text, graphics, color) and dynamic (animation) visualization of information; a reference that includes a contextual help system that contains information about how to work with the system, learning goals and tasks, and the necessary additional methodological material; control and diagnostic, including computer means of fixation and processing of test results.

Interactivity, search engine and hypertext links give the trainee an active position when working with the textbook-simulator, allow them study the content nonlinearly, and provide possibility to choose individual trajectories and pace of leaning. Harmonious combination of animation, graphics, color, and interactivity provides visual and figurative perception of educational content. The textbook meets the requirement of openness, providing an opportunity to complement, modernize, and introduce new material.

4 Three-Dimensional Dynamic Computer Simulator

The advantages of virtual simulations include, in particular, attractive interfaces, authenticity at lower costs, stimulation of critical thinking and creativity, greater freedom for students in the ability to act by trial and error. An example of virtual simulation of interactive type is a three-dimensional dynamic computer simulator used in training of engineers for electrotechnical and electroenergetic industries at the Department of Electric Drive and Electrical Engineering.

The simulator reproduces the energy object and reliably visualizes changes in the state of electrical and technological equipment. Simulator software modules include: (1) Mathematical model of power supply system of the enterprise. (2) Virtual three-dimensional environment of the enterprise power supply system. (3) 3D-models of objects. (4) Dynamic models of electrical equipment and power supply systems. (5) Educational and methodical support. (6) Expert system of knowledge assessment.

The use of the simulator is based on the gamification of the learning process in a virtual environment, accompanied by mathematical modelling and methodical support.

All software modules are connected to each other through the interfaces for data export/import that create a dynamically changing environment based on the calculations of the main electrical parameters of the system: currents, voltages in the circuit sections, as well as abnormal and emergency modes of operation of the network. All items of equipment at the facility are not static, and allow to perform on them any operations that are feasible at the facility (enable, disable, disassemble, assemble, etc.) (see Fig. 2).
Fig. 2.

Virtual reality in simulator environment

As a result, a student can navigate in a virtual environment to any electrical facility and simulate any possible real-life hardware action. In real time, electrical circuits are recalculated and the state of the equipment is visualized if the student’s actions lead to their change. It is also possible to visualize abnormal and emergency situations. Emergencies have been included in the scenarios of standard training situations. The expert system subsequently assesses student’s actions on elimination of accidents or abnormal conditions at the facility (see Fig. 3).

There are two modes of simulator exploitation: training and knowledge testing.

In the training mode, students experience the effect of full presence at the real energy station due to the perfectly exact representation of the energy object.

Educational and methodical support includes a set of exercises, 3D-models, animations and instructional videos. Training videos give an idea of the electrical equipment, the principles and modes of operation, as well as the power supply circuits of objects. All aspects of equipment operation are disclosed: the physics of the processes occurring inside the equipment (i.e., the energy diagram of an asynchronous motor); the interaction and interrelation of the equipment components (i.e., functioning of the secondary winding of the oil transformer on the armored type magnetic circuit); connection with other external equipment (i.e., connection between electric motor and frequency drive), etc. Training videos can be used for both individual and group training.

Students can also acquire skills in the design of the documentation used at the facility (i.e., to learn the paperwork carried out by the department of the company’s chief energy specialist).

There are also a number of virtual instruments, devices and personal protective equipment against electric shock in the environment. A student can study them through the developed help system, consider internal components and apply them in an intuitive way (i.e., unscrew a nut, tighten a nut, apply grounding, hang a poster, etc.). All actions of students in the training mode are accompanied by text and video tips (see. Fig. 4).

Students enjoy complete freedom of action that allows them to make a mistake in a virtual environment, not in a real life, see the consequences, understand the reasons, and take successful or unsuccessful attempts to eliminate the consequences of erroneous actions.

The second mode of operation allows assessing the level of knowledge and competencies of students in simulating various abnormal and emergency situations at the facility in the virtual environment.

The capabilities of the expert system allow the instructor: (1) To edit the situation at the facility, formulate tasks, set the order of the correct actions expected from the learners. (2) To implement basic scenarios of individual and collective work with the electrical equipment. (3) To set the required number of points (percent) for completed assignments. (4) To analyze and display statistics on the achievements of both an individual student and student groups. (5) To save and export/import evaluation sheets by time.

5 Experiment on the VR Use in Chemical Laboratory Practical Workshops

Another direction of developments in the VR use in the educational process of KNITU is a study of the effectiveness of VR technologies in performing laboratory chemical practical workshops in the process of training vocational teachers for chemical industries being conducted at the Department of Engineering Psychology and Pedagogy.

Laboratory chemical practical workshops play an important role in the training of vocational teachers for chemical industries. Chemical education includes an integrated set of vocational practical workshops in all parts of chemical science, including polymer chemistry. Meanwhile, most of the equipment being currently exploited in chemical practical workshops at technical universities has been acquired and installed in the last century. The modern equipment used in the processing of polymeric materials – installations for pressing, injection molding, and extrusion – is expensive, and therefore its usage in the educational process is difficult. Accordingly, both the hardware and the methodological support of chemical practical workshops do not meet contemporary requirements challenges.

The analysis of the literature and practice of training specialists for chemical industry [2] has shown that there are a number of VR applications being used in training of chemical engineers [3, 4, 5, 6]. In general, however, computer support for laboratory practical workshops is not a common practice, and the potential of impressive technological capabilities of VR for visualizing chemical structures and processes is still to be exposed. It is important to answer the question on how virtual forms of modeling technological processes of chemical production and chemical experiments in technical universities could promote students engagement.

The ongoing research covers one of the most promising, according to researchers, directions for application of VR in education – visualization of objects invisible with ordinary vision and of abstract theoretical concepts. We plan to conduct a comparative study on how three-dimensional visualization of chemical molecules and virtual models of technological processes in the formats of a computer screen and VR glasses affect learning outcomes.

As part of the research, the structure and content of the laboratory practical workshop on the discipline “Raw materials for the production of polymeric materials” with computer support is being developed. Its innovative character is determined both by the use of VR technologies and by new approaches to the development of methodical support. Special software tools are being created in Gaussian and Jmol programs and on the Unity platform, providing interaction between participants of the educational process. New opportunities of the practical workshop consist in visualization of three-dimensional models of chemical structures and virtual models of technological processes; the use of real experiments and technological processes videos; modeling of emergency situations taking place in technological cycle; a dialogical environment involving interactive actions of students on finding exit of them; and an extensive system of contextual assistance.

Pedagogical approaches to the design and implementation of laboratory practical exercises based on three-dimensional visualization include the following procedures: identification of didactic units of the academic discipline and problematic situations, containing basic knowledge for the design of a laboratory practical workshop; creation of three-dimensional models of chemical structures, chemical reactions and virtual models of technological processes, as well as scenarios of problematic situations; implementation of group activities by students on compilation of assignments based on elements of laboratory practical workshop.

As part of the study, it will be examined how the format of presentation of VR objects – a computer screen and VR glasses – affects the intensity of intra-group interactions of experiment participants in solving group tasks in VR, and what is an impact of dialogical information environment on communications intensity.
