Purpose The purpose of this paper is to show the effectiveness of innovative mobile technologies in learning, to develop a new testing system with a mobile application and to investigate the influence of its use on the level of students’ knowledge. Design/methodology/approach Modern information assessment methods of knowledge, testing, including application of mobile devices and statistical analysis tools were used in the present research. Findings In recent times, students are motivated to use mobile technologies in education. This paper offers one of the approaches for achieving the effective integration of mobile technologies into the learning process. The software is developed for in-class testing as a client-server and its mobile application. Practical implications The practical research verified many advantages of mobile device usage during testing. It contributes to higher academic performance; in addition, it is economically advantageous as it does not require special equipment in classrooms and is psychologically comfortable for students who are accustomed to constantly using their mobile devices. Social implications Well-educated people play a role in the development of modern society. Mobile technologies can transform education into a seamless part of the ordinary life so that a person does not recognize it as training at all. The learning process will become more natural and easier and that will improve its quality. Originality/value This paper demonstrates how mobile devices can satisfy the learning expectations of students who frequently use mobile services on the Web and can attract their study interest implementing the created testing system in full-time education process.

Визначено закономірності впливу параметрів шихти на вміст Cr та Ni в продуктах відновлення. Досягнуто межі вмісту відповідних елементів: 15,1-17,1 % мас. та 0,2-7,0 % мас. Встановлено, що продукти металізації в основному складалися з твердого розчину легуючих елементів в α-Fe. Також виявлено оксид Fe 3 O 4 і карбіди-Fe 3 C, Fe 2 C. Мікроструктура губчаста розупорядкована. Мікрочастки спечені, з різним вмістом Cr та Ni Ключові слова: переробка відходів, корозійностійка сталь, вуглецевотремічне відновлення, фазовий аналіз, мікроструктура, ресурсозбереження Определены закономерности влияния параметров шихты на содержание Cr и Ni в продуктах восстановления. Достигнуты пределы содержания соответствующих элементов: 15,1-17,1 % мас. и 0,2-7,0 % мас. Установлено, что продукты металлизации в основном состояли из твердого раствора легирующих элементов в α-Fe. Также выявлены оксид Fe 3 O 4 и карбиды-Fe 3 C, Fe 2 C. Микроструктура губчатая разупорядоченная. Микрочастицы спеченные, с различным содержанием Cr и Ni Ключевые слова: переработка отходов, коррозионностойкая сталь, углеродотермическое восстановление, фазовый анализ, микроструктура, ресурсосбережение

Sustainable development of border areas is a critical factor in ensuring the national security of Russia. In this regard, it is important to apply a number of research approaches to assess the state and identify positive changes occurring in this area. The relevance of the article is due to the problems of scientific support of these processes. Contemporary approaches to the consideration of aspects of sustainable development of border areas are analyzed in the context of this study. Based on the systematization of scientific publications, the least covered research areas are identified. More than that, topical issues that allow stakeholders to assess the sustainability of development of border areas are proposed.
