SUMMARY
The article considers current trends in the use of mobile devices for knowledge assessment tests. It provides an analysis of the market of software products that are designed to create mobile applications. The analysis is based on the level of computer literacy that is needed when using the considered software products for the development of mobile applications. According to the mentioned classification approach, three groups have been highlighted: a) developers with professional programming skills, b) developers without any knowledge of a programming language, c) based on a web interface. The authors note that the diversity and inherent capabilities allow most instructors to create high-quality applications for conducting test control of knowledge of engineering students via a mobile device. An assumption is made that the introduction of mobile devices into the educational process for conducting knowledge assessment activities would be more successful if the specifics of the professional and practical preparation of students, future engineers are taken into account. A peculiarity of these classes is that graphic images are often used as the source data and results of the completion of the training assignments. According to those performance results, engineering students should know the design of the complex technical devices and learn how to manage them. Therefore, for knowledge assessments, one should ensure the inclusion in the test of test items with graphic illustrations, including large-sized images. It is important to be able to carry out knowledge testing using mobile devices, including in practical classes at the student laboratories and at the production facilities, where it is difficult to provide access to mobile communications. The mobile application SSUquestionnaire-m is described. It allows to take into account, to a large extent, the features of an engineering education noted in the article and to present all students attending the lesson, with the application’s control measures. At the same time, it is not necessary to switch to combined mobile control technologies and, limiting the possibility to use only students' mobile devices, to carry out all control measures in one session.
