Features of conducting laboratory work on chemical disciplines in a blended educational format using cloud services in institutions of higher education

Abstract

The training of students in higher education institutions of Ukraine during the period of martial law is characterized by compliance with the measures of a safe educational environment for those seeking education. The leading form of education, as shown by the positive domestic experience gained during the pandemic, remains the mixed form of education. In the framework of which, the implementation of the acquisition of practical skills of the students, in particular, the high-quality performance of laboratory work in chemical disciplines in full, appears as an urgent issue. Modeling the real conditions of a chemical laboratory, including taking into account the necessary equipment and reagents, makes it possible to thoroughly and comprehensively implement synchronous distance learning of students, to fully cover the theoretical material, to practice under the guidance of a teacher, the methods of conducting laboratory work in chemical disciplines in an interesting, accessible and visual form. The article analyzes the ways of software implementation and presents an overview of the most used tools for successful laboratory work in chemical disciplines, taking into account the expert assessment of the participants of the pedagogical experiment. Summarizing the results of the study, it was found that among the respondents, free applications for mobile phones with an intuitive and understandable interface became the most used and accessible for understanding, in particular: virtual chemical laboratories, editors of chemical drawings, sets of flash cards of chemical content. Realistic visual image, open constant access of materials, speed of calculation of input data and obtaining results are defined as significant advantages of the presented training tools. The article analyzes the state of use of cloud services during laboratory work in chemical disciplines in the mode of mixed form of education. The pedagogical experiment proved the effectiveness of using modern tools and teaching aids, the use of virtual chemical laboratories, mobile applications for modeling chemical processes, and cloud services for visualization of chemical disciplines in the educational process.
