Visual approaches to the teaching of methods of food quality control using distance learning means during combat actions

Abstract

The problem of ensuring the quality of education during hostilities is related to the search for the most
effective methods of distance learning. The introduction of visual methods, equipped with modern computer
tools, allows to significantly increase the effectiveness of training. In this study, the implementation of visual
control methods in the process of ensuring the professional competences of students in areas related to the food
industry is substantiated. The importance of virtual control of portions of food products, which provide the
necessary energy value, has been proven on the basis of research on the issue. Based on the study of
educational programs of the specialty "Vocational education (Agricultural production, processing of agricultural products and food technologies)" the main competences related to the control of the quality of food
products by visual means have been determined. The study of the effectiveness of the formation of
competences by visual means was conducted among 131 students of the 1-4 years of education. The paper
outlines an order of classes using visual methods, which includes updating and correcting competences in the
direction of forming portions of food products, formulating goals, discussing the content and application of
methods of observation, analysis and generalization of visual information, issuing visual tasks for determining
the sizes of portions of food products, prompt execution of tasks by students, transfer of data to electronic
spreadsheets on Google Drive, automatic construction of distribution, discussion of the results obtained with
students, determination of directions for correction of the results, substantiation and reflection on the results.
The parameters of the distribution of the results over several iterations are determined. Sufficient accuracy of
determining parameters of product portions after three iterations of training has been proven. The research
substantiates the provision of the main descriptors of learning in the form of knowledge, its use, and processes
of developing opinions, communication skills, autonomy and responsibility. The effectiveness of the above
methods was tested and confirmed in the conditions of the real educational process.
