AbstractWhen university instructors face the need to train students on an experimental science, it means there should be a strong load of learning how to work in a laboratory, to understand the techniques, and to interpret results. However, it is often the case that there are difficulties associated e.g. to the lack of laboratory space, instrumentation or time in the course schedule. This article presents some guidance that may help in choosing, designing and particularly implementing practices around virtual laboratories and other simulations of experimental environments and techniques. The objectives are to provide a more active and significant learning, by engaging students in the process, to support and facilitate the practical sessions and, in cases where real experiments are not feasible, to provide some alternative exposure of the students to the laboratory work.

Laboratory work in science education is essential for students' conceptual understanding of natural phenomena. Computer-simulated laboratory experiments have been proposed to facilitate traditional laboratory work. A virtual laboratory was designed to enable students to collaboratively discover the concept of gas solubility in water at different physiological conditions. The virtual laboratory was developed through a design experiment involving three successive versions with different guiding structures. Analysis of 12 dyads' reasoning about gas solubility in water revealed that the problem was not primarily for the students to realise how the volume of gas changed, but rather to understand the concept of solubility of gases. It was also observed how the guiding structures within the three different versions influenced the students' reasoning about the concept. The analysis indicates that the affordances of virtual laboratories might, to a certain extent, enhance joint discovery of a scientific concept.

В процессе подготовки будущих учителей физики основное внимание следует уделять не передаче суммы готовых знаний, а знакомству обучающихся с методами научного познания окружающего мира, постановке проблем, требующих от учащихся самостоятельной деятельности по их разрешению. В процессе обучения в первую очередь следует обратить внимание на то, что физика – наука экспериментальная, но при переходе к познанию микромира и мегамира снижается возможность реализации экспериментальной деятельности обучающихся. Авторами предлагается один из способов практического решения этой проблемы, заключающийся в организации и проведении лабораторных занятий с использованием разработанной виртуальной версии лабораторных работ по квантовой физике, способствующей развитию профессиональных компетенций будущего учителя физики. Также в статье рассматривается использование разработанного авторами методического комплекса «Цифровые лабораторные работы при изучении школьного курса физики», который представляет собой лабораторные работы с использованием реального оборудования с цифровыми датчиками, сигнал с которых обрабатывается на компьютере. В состав комплекса включены учебно-методические материалы для подготовки, выполнения и защиты лабораторных работ. Для достижения цели авторы использовали следующие методы исследования: теоретический анализ состояния проблемы на основе изучения методической, дидактической, психологической и специальной литературы, диссертационных работ по проблеме исследования; материалов конференций по использованию цифровых технологий в физическом образовании, нормативных документов, определяющих структуру и содержание профессиональной подготовки учителя физики, изучение и обобщение педагогического опыта; компьютерное моделирование физических процессов, наблюдение, беседа, анкетирование, интервьюирование, проведение педагогического эксперимента. In the process of training future physics teachers, the main attention should be paid not to transfer the amount of ready-made knowledge, but to familiarize students with the methods of scientific knowledge of the world around them, and to pose problems that require students to independently solve them. In the course of training, first of all, you should pay attention to the fact that physics is an experimental science, but when you move to the knowledge of the microcosm and mega world, the possibility of implementing students’ experimental activities decreases. The authors suggest one of the ways to solve this problem in practice, which is to organize and conduct laboratory classes using the developed virtual version of laboratory works on quantum physics, which contributes to the development of professional competencies of future physics teachers. The article also discusses the use of the methodological complex developed by the authors "Digital laboratory work in the study of school physics", which is a laboratory work using real equipment with digital sensors, the signal from which is processed on a computer. To achieve this goal, the authors used the following research methods: theoretical analysis of the state of the problem based on the study of methodological, didactic, psychological and special literature, dissertation works on the problem of research; materials of conferences on the use of digital technologies in physical education, normative documents that determine the structure and content of professional training of physics teachers, the study and generalization of pedagogical experience; computer modeling of physical processes, observation, conversation, questioning, interviewing, conducting a pedagogical experiment.

As you know, improving the education system of students in the learning process has become one of the fundamental problems of modern Soviet pedagogy and psychology and didactics, and in the context of scientific and technological progress and the transformation of the public education system, it is of particular importance. It is especially important that the school teaches not only to give specific knowledge, but also to draw conclusions, make decisions, conduct research based on this knowledge, i.e. to form creative thinking skills. Much attention is paid to the content of the subject of chemistry, technical equipment and methods of organizing laboratory work in scientific and methodological, psychological and pedagogical research literature. The main role in the study of chemistry is played by chemical laboratories, which are an integral part of the educational process. Laboratories are divided into several types depending on the area of application. One of them is virtual laboratories. Using virtual laboratories, logical generalization and visual refinement of the course of training. Application of effective methods and techniques for working with modern software in creating virtual laboratories. Its special feature is that it analyzes problems with other laboratory work.

One of the fundamental requirements of engineering education is laboratory work and practical teaching. The main purpose of the laboratory is to provide a space for students to carry out practices that allow them to check the theory learned in the classroom, validate hypotheses, propose solutions and recommendations, develop critical thinking skills and develop soft skills. The provision of laboratory work to engineering students helps them familiarize themselves with similar situations as they will find real life as they practice their profession. Primarily, this laboratory work is based on actual hardware and a laboratory where the students can work at a specified time, perform experiments under the guidance of a lab technician and leave with data that they can analyze later using the knowledge they learned in class. These laboratories and the hardware equipment in them are expensive to acquire and maintain. Also, they are an expensive upgrade, yet upgrading is inevitable with the rapid change in technology we are all experiencing. Various institutions have been forced to use outdated laboratory hardware or do with minimal hardware for performing engineering experiments. However, the rapid increase in technology that is contributing to the problem can be used to solve it by having a suitable front-end design in computers that can be used to simulate experiments.

The article highlights the results of the organization of laboratory work using a modern digital training panel on electricity in a laboratory workshop on physics, which was developed and manufactured in Lutsk by the R & D center Mirroschool. As a result of the research, we proposed a method of organizing laboratory work in physics using a training panel. The article contains a fragment of laboratory work in physics, which allows to intensify the cognitive activity of students in teaching physics. The guidelines will be useful primarily for physics teachers and instructors who conduct laboratory work and demonstrations on electricity, laboratory technicians in physical laboratories who work with physical equipment, and will be useful to students who master the knowledge of experimental science. The training panel on electricity fully provides training rooms for physical classrooms, laboratories and training facilities in the section «Electrodynamics», which are used in the school curriculum approved by the Ministry of Education and Science of Ukraine. The panel can be used by both teachers and lecturers in higher education institutions. Of course, laboratory work and demonstrations of general secondary education institutions are quite easy to modernize and adapt, which allows you to use other training panels that are presented in the market of educational equipment. But when it comes to higher education or colleges, the list of laboratory work can be significantly reduced, or simply have to use additional educational equipment and laboratory workshops. The electric training panel is a modern, school, educational equipment, which, among other things, successfully agrees with the educational norms of the new Ukrainian school and STEM education. The panel meets all requirements: language legislation, education standards, compliance with sanitary legislation, fire and electrical safety, health care requirements, etc. Also, all consumables are available for purchase in Ukraine. Key words: laboratory work, demonstration, method, training panel, education.

The increasing use of online virtual laboratories (OVLs) in educational institutions as a recent educational technology application necessitates developing a new educational platform for assisting instructors in using such technology in the teaching process without web programming obstacles. The OVLs are online environments that provide students with several types of content such as simulations, videos, scientific images, and infographics related to real laboratory experiments. This article proposes a unified online virtual laboratory platform (OVLP) to support instructors who teach real laboratory experiments in multi-domains. To evaluate the proposed platform, five university instructors and five experts of ICT in education have participated in this study. The data were collected using online questionnaires for both specialists, respectively. Regarding the results, they confirm that the proposed platform is acceptable for teaching real laboratory experiments, especially in the tested domains.
