    The purpose of the study is to identify the characteristics of implementation of remote access to learning at university basing on distance learning technology. The basic methods for the relevant problem studying are pedagogical experiment, expert assessment methods, and statistical processing of quantitative results of the research. The experiment involves the students and professors of the Ammosov North-Eastern Federal University (NEFU), the Herzen State Pedagogical University of Russia (RSPU) and Chelyabinsk State University (CSU). The promising areas of distance learning and its effectiveness have been analyzed and generalized. In addition, factors and conditions for providing quick access to the Internet for the educational process have been identified. The substantive aspect of the implementation of remote access to learning in terms of the Major Professional Educational Programs (MPEP) in the field of Pedagogical Education is examined in order to identify their relevance to the distance learning implementation at university.

    The development of technology puts forward more complex problems, the effective solutionof which is associated with the refinement of mathematical models of the studied plastic formingprocesses of metal systems (metals, steels, non-ferrous alloys) of various chemical compositionsand production technologies (traditional ingot processing, powder production, nanostructuredmaterials). To build a solution, the integration of differential equations to describe the physicalprocesses occurring during plastic flow or a variation approach based on the construction ofthe original functional is used, but in either case the accuracy of the mathematical modellingof the process will depend on the accepted mathematical model of the medium. The paperdiscusses the development stages of different models of plastic media, from a simple rigidplasticmodel, without taking into account the change in the material properties, to morecomplex ones - a viscoplastic model that regards the appearance of viscosity with increasingprocessing temperature and a dilating model that allows to take into consideration changes inmaterial density and thereby predict strain destruction. The correct use of mathematical modelsof plastic media makes it possible to improve the accuracy of technological regimes calculation,thereby reducing the time to develop the new product, and can be used for the developmentof technological processes for obtaining products by means of the additive technology basedon laser sintering and fusing the powder alloys, thermoplastic processing technologies andprocesses of thermochemical hardening and heat treatment of metallic systems of differentchemical compositions.Развитие техники выдвигает более сложные задачи, эффективное решение которыхсвязано с уточнением математических моделей изучаемых процессов пластического формоизменения металлических систем (металлов, сталей, цветных сплавов) различных химических составов и технологий получения (традиционный слитковый передел, порошковое производство, наноструктурные материалы). Для построения решения используется интегрирование дифференциальных уравнений, описывающих физические процессы, происходящие при пластическом течении или вариационный подход, основанный на построении исходного функционала, но в том и другом случае точность математического моделирования процесса будет зависеть от принятой математической модели среды. В работе рассмотрены этапы развития различных моделей пластических сред, от простейшей жесткопластической модели, не учитывающей изменение свойств материала, к более сложным – вязко пластической модели, учитывающей появление вязкости при повышении температуры обработки и дилатирующей модели, которая позволяет учитывать изменение плотности материала и тем самым прогнозировать деформационное разрушение. Правильное использование математических моделей пластических сред дает возможность повысить точность расчета технологических режимов, сокращая тем самым время на освоение выпуска новой продукции и может быть применено для разработки технологических процессов получения изделий методами аддитивных технологий на основе лазерного спекания и сплавленияпорошковых сплавов, технологий термопластической обработки и процессов упрочняющейхимико-термической и термической обработок металлических систем различных химических составов

    The development of adaptive tests is based on taking into account the predominant individual characteristics of students, that is the style characteristics of cognitive activity, making it possible to increase the effectiveness of tests, make them more attractive, and ultimately contribute to more effective learning. In this context, the paper presents the results of a study on the effectiveness of students' adaptive computer tests based on the consideration of the stylistic characteristics of their cognitive activity. Based on computer science and programming, variations of test items were developed and offered to undergraduate and graduate students at Herzen State Pedagogical University of Russia and ITMO University Saint-Petersburg. In the course of the study, it was revealed that since the adaptive test passing scores showed a stable improvement, the desirability and possibility of constructing tests based on the consideration of stylistic features of students' cognitive activity was experimentally proven. Similarly, the hypothesis about the effectiveness of using adaptive test questions in comparison with other types of questions was proven.O desenvolvimento de testes adaptativos baseia-se em levar em conta as características individuais predominantes dos estudantes, ou seja, as características de estilo da atividade cognitiva, tornando possível aumentar a eficácia dos testes, torná-los mais atraentes e, finalmente, contribuir para um aprendizado mais eficaz.
