INTRODUCTION Virtual laboratories have been  used for several decades as a tool to help in the educational process. However, it is not always clear the purpose and correct way to use this tool. Educators need to improve their work so that the teaching process is more efficient. A wide range of virtual resources is available in different languages. Most of the resources are in English and some in Latvian, therefore the use of virtual laboratories is made very simple. Hypothesis: The efficient use of a virtual laboratory depends on multiple circumstances. The concept of the virtual laboratory is understood and used differently by many authors and researchers because that depends on the purpose of use. In the most general terms, a virtual laboratory is a computer-based activity where students interact with an experimental apparatus or other activity via a computer interface. Typical examples is a simulation of an experiment, whereby a student interacts with programmed-in behaviours, and a remote-controlled experiment where a student interacts with real apparatus via a computer link. This kind of process allows students to explore a topic by comparing and contrasting different scenarios, to pause and restart an application for reflection and note taking, to get practical experimentation experience over the Internet. The most recognizable are computer simulations that allow us to examine basic concepts in physics. These simulations are broadly used in the teaching and learning process in different ways. The purpose of this research is to study through virtual laboratories that are broadly used in educational institutions and to examine the usefulness and impact of using such laboratories. MATERIAL AND METHODS To find out the circumstances for the efficient use of a virtual laboratory, research has been made to understand the key factors. A criterion for effectiveness of the virtual laboratory is made depending on other experiences over the past ten years. Mostly through literature studies and depending on experience, all the assumptions are justified. RESULTS What people mean by a virtual laboratory, to understand what value it can bring, and importantly what it cannot and must not do. A virtual laboratory must bring as close a connection to reality as possible, to as many students as possible. The key areas of benefit are accessibility, training and augmentation. Nothing can replace the experience of working hands-on with laboratory equipment, the virtual laboratory should not be used to provide a full experience. In some cases, learning a new environment or software for simulations can be difficult and time consuming. In the context of geographical location or mobility issues, the use of a virtual laboratory may provide a substitution for a real experiment. A substitution is also necessary due to lack of equipment. DISCUSSION In recent years, researchers do not try to prove that virtual experiments are better than experiments in real life because such researches were made and the results in most cases do not prove that virtual experiments bring better results in students’ exams. Different researchers try to prove that using virtual environment in some cases changes the attitude towards physics and science. In future authors will make and use virtual laboratory not only as computer simulations but also as a whole environment for learning and teaching physics and science. CONCLUSION The results are theoretical. However, this research is significant for future work because it helps to prevent failures and focus on things that have not been done before. There exist some limitations due to a lack of students. Therefore, the authors can also focus on different stages of education.

Distance learning has already become a part of the educational process. In this regard, questions appear concerning its organization and the solution of specific problems. They include laboratory workshops, which is an integral part of the educational process in higher education since laboratory works allow students to gain knowledge and acquire skills, which is a prerequisite for the formation of their specialist competence. The problems of obtaining educational information during distance learning can be quite successfully solved. However, the acquisition of experimental skills remains an educational, scientific, and methodological problem that requires a solution. The article defines the peculiarities of using virtual laboratory workshops in the online education of students studying the discipline “Inorganic Chemistry”. The theoretic analysis of the main statements of the research problem was presented in the article. The results of the experimental study have proved that the use of computer modeling and the tools of a virtual laboratory when studying chemistry disciplines increases the educational achievements of the students, regardless of the initial level of knowledge. A prerequisite for the effective acquisition of skills by students is the systematic use of virtual laboratory tools. With the occasional use of virtual laboratory instruments, the skills obtained during the experiment were not learned or were not learned for a long time. The use of virtual laboratories provides independent training for students, increases motivation to master new material. Students focus on the experimental process, not on equipment and tools, as it happens in a real laboratory, which can become both a positive and a negative aspect of acquiring practical skills of future engineers, doctors, and pharmacists.

The introduction of information and communication technologies in the educational process of teaching various disciplines is becoming increasingly important. Accordingly, the issue of application of these technologies in the teaching of chemical disciplines is relevant, namely the study of the possibility of using virtual laboratories in Chemistry as an interactive learning tool to improve the learning process and provide opportunities for professional and research skills. The purpose of the article is to study the possibilities of using virtual laboratories in the process of teaching chemical disciplines and to determine the opinion of students on the effectiveness of this type of activity. The following research methods are used in the article: theoretical – analysis of scientific publications on the research problem; systematization and generalization of information; empirical – questionnaires and analysis of its results. The article considers the advantages and disadvantages of using virtual Chemistry laboratories in the educational process. The article analyzes the concept of «virtual laboratory» and gives the definition of a virtual laboratory of Chemistry as a software environment that allows to form practical skills by conducting laboratory experiments, simulating the sequence of actions of the researcher in real laboratory (or managing chemical plants by robotic means) with use of computer models or contactless (remotely) with real equipment and reagents. We consider the virtual Chemistry laboratories available on the Internet, which provides free access to the educational resources and explores their didactic and methodological opportunities to increase the level of formation of practical skills and abilities during chemical experiments. It is established that the use of a virtual laboratory in Chemistry contributes to the formation of practical skills in conducting interactive laboratory classes with further consolidation in real conditions; provides an individual pace of mastering the skills of chemical experiment; allows students to explore processes that require special conditions; increases the motivation to master new material by working in a virtual environment that is familiar and interesting for the modern student; provides realization of its independent preparation for performance of experiments in real laboratory conditions. It is substantiated the use of virtual laboratories in Chemistry cannot substitute the traditional performance of laboratory work, but is only a supplementary form.

The article considers industrial applications of digital twins and their contribution to decision-making and prevention of failures in manufacturing. Virtual laboratories are described as an example of using digital twins not only in industry but also for educational purposes. The article is also focused on the value of physical and virtual investigations through the prism of content and language integrated learning approach (CLIL) and it offers recommendations for combining the two to strengthen science inquiry learning and job-relevant learning. Students conduct online investigations resulting in interdisciplinary team interaction and knowledge integration. Adopting the CLIL approach changes engineering students’ attitudes to learning a foreign language, drums up their academic interest, and strengthens their motivation. In addition, the article describes how neural networks are applied for the simulation of physical processes in a virtual laboratory. The advantages of using virtual laboratories for professional-oriented training include linking observable and unobservable phenomena, pointing out essential information, and providing online, adaptive guidance. To evaluate the efficiency of the virtual laboratory environment, we conducted an experiment to assess the effectiveness of an integrated learning course with the elements of a virtual laboratory. The sample was 48 students (23 of them were enrolled on the course based on integrated learning with elements of virtual environment; 25 students studied professional discipline and professional English separately). To collect the data two online testing on English were conducted. The professional discipline was evaluated once at the end of the semester. In addition, we conducted an online survey on motivation for students of both groups to reveal the influence of educational process organization on this indicator. The results of the experiment allowed us to ascertain that the CLIL approach in the virtual laboratory environment resulted in better outcomes and helped the students adopt a more positive attitude to learning English.

The accelerated pace of scientific and technological development of modern Ukrainian society, is steadily striving to unite with the world community, puts the requirement for urgent modernization in front of the traditional higher school. The quality of education to an outstanding extent depends on the effectiveness of communication in the “teacher-student” system. Our proposed form for the study of childhood infectious diseases allows to bypass the imposition of the authoritarian thought of the teacher. This is achieved through the formation of a productive team of teacher – students on mutually beneficial conditions of cooperation on the basis of bilateral (both of the teacher and the student) internal motivation. The basis of innovations in the teaching of medicine today is the introduction of interactive cooperation between those who help to study, and those who study, and problem-oriented learning. Therefore, in the study of children's infectious diseases by graduate students, the practical lesson is based on thematic (according to the topic of the practical lesson) supervision of the patient in the presence of the attending physician and under the supervision of the teacher. This is a real child with a real problem, and therefore, the teacher created an original task, tied to a real life situation. Such a clinical task for its solution requires the student to independently apply a wide range of knowledge and skills in the studied discipline in related subjects. A role-playing game begins: the attending physician (the student who observed the patient) invites other specialists (the rest of the group's students) to the council to help make a diagnosis. Prospects for further improvement of the educational process in the study of pediatric infectious diseases will relate to stimulating interest in the subject by promoting the idea of ​​involving students to actively participate in the development of their practical skills through elements of research work within the scope of the work program.

The article analyzes organizational and content features of social rehabilitation students’ professional training at higher education institutions in the United States. The two-year college programs for obtaining Associate’s degree, four-year Bachelor’s and interdisciplinary Master’s degree university programs for professional training in social rehabilitation have been characterized. The peculiar features of these programs for each academic degree have been determined. It has been identified that professional training is carried out on an interdisciplinary basis by integrating general scientific, professional and subject-specific knowledge, introducing wide range of elective courses. Three models for training social rehabilitation students have been defined: traditional didactic, problem-solving and facilitated. Preference is given to the facilitated model, the conceptual idea of which is the idea of an integral professional and personal development of a social rehabilitation student as a subject of educational process throughout the study period and further professional activities. According to these models, the key teaching technologies have been divided into three groups: traditional didactic (demonstration, asking and answering questions), problem-solving (discussions, problem-based situations, conversations) and facilitated (interactive technologies such as round-table discussions, brainstorming activities, case study etc.). It has been found out that American college and university teachers prefer interactive (group learning, gaming, reflective, combined, integrated, project-based, information and communication) technologies, the essential features of which are the problem-based nature of co-operative learning, partnership and dialogue. Effective use of interactive technologies helps to involve students in the process of cognition, develops students’ critical thinking, encourages them to participate in learning activities, become independent, develop their professional outlook, reflect upon their own educational and cognitive activities by promptly defining their learning outcomes, modeling real life situations, creating the atmosphere of community and co-operation. It has been found out that the system of professional training provides conditions for professional self-determination, self-development and self-improvement.

This study compared the grasping performance of 24 younger (20-30 years of age) and 24 older subjects (60-70 years of age) in a typical laboratory task (L) where movements were repetitive, externally triggered, purposeless and attention-attracting, and in an everydaylike task (E) where movements were part of a rich behavioral repertoire, internally initiated, purposive and little attended. We registered a wide range of kinematic and force parameters, and calculated their within-subject means and variation coefficients. Multiple differences emerged between the parameter values in L and E. Factor analysis reduced them to five independent effects. We also found multiple differences between the two age groups, with seniors responding more slowly and in a more stereotyped fashion. Multiple significant task x age interactions emerged as well, with age differences being more pronounced in E than in L. The latter finding is of practical relevance, since it suggests that age-related deficits in some real-life situations may be underestimated in laboratory research. It also is of theoretical relevance: it indicates that brain regions which are particularly vulnerable to aging may contribute to task E more than to task L.
