Digital technologies in the training of engineering personnel for the agro-industrial complex

The models and methods of creation and practical use in the training of engineering personnel for the agro-industrial complex of digital information and reference manuals are considered. The possibility of deep structuring of educational content, including graphic images of models of the studied objects of agro-industrial equipment, has been studied. A set-theoretic model for organizing object storage and processing of systematized and structured educational content is presented. A method for structuring images (drawings of parts and products, diagrams, drawings of technical objects of agro-industrial equipment) is described for the purpose of subsequent implementation of learning management using multivariate scenarios with free transitions through the content. A learning management model has been developed using educational content generated on the basis of graphic markup maps. It is shown that the interactive educational content of digital information and reference manuals for the effective training of technical specialists for the agro-industrial complex should be generated from the minimum didactic units of structured and decomposed educational content stored in the form of specially arranged formalized objects. A method has been developed that makes it possible to implement multivariate scenarios of interactive learning in the study of graphic engineering disciplines. An algorithm for implementing transition management for educational content based on the use of markup maps of graphic images in digital information and reference manuals is presented. Examples of the practical implementation of the described models and methods for managing the content of digital reference guides based on image structuring and the use of multivariate scenarios are given. It has been established that the practical application of digital information and reference manuals created on the basis of the models and methods described in the article showed high efficiency in the study of engineering disciplines in the preparation of engineering personnel for the agro-industrial complex-the quality of assimilation of educational material during independent work of students increased by an average of 20-25%.
