Using the iSpring Suite computer platform in distance learning

. The article discusses the experience of using the iSpring Suite 9 computer platform as an information tool for conducting distance classes with second-year students in the training for "Business Informatics". Self-isolation requirements in the face of the COVID-19 pandemic have required the development and use of innovative remote learning methods. The need to conduct practical classes on solving technical problems with mandatory time control and prompt receipt of the results of the solution by the teacher determined the requirements for the choice of a computer program as a tool for providing distance work in the field of education. As a result, the choice was made in favor of the corporate training platform iSpring. According to the results of the spring semester, the experience of working with iSpring Suite 9 in creating electronic tests and conducting practical exercises in distance mode was recognized as successful and will be used in the future to conduct classes with students of the distance department of Novosibirsk State Technical University.


Introduction
The COVID-19 coronavirus pandemic has seriously affected all aspects of human activity. The requirements of almost universal self-isolation caused a significant decrease in the overall level of production the lack of effective measures developed to combat infection only worsened the already difficult situation.
This terrible disease had no less impact on the development of education. The urgent requirements to ensure the safety of the health of all participants in educational activities (from schoolchildren to heads of universities) have led to the need to look for various forms of distance education that would sufficiently compensate for the lack of full-time education opportunities.

Information tools requirements for distance learning
In these difficult conditions, practically each of the school teachers and university professors tried their own methods of working with remote access, using the capabilities of modern information technologies.
The matter was complicated by the fact that there was absolutely no time for a serious study of the distance learning methodology: it was necessary to ensure the implementation of the curriculum every day. That is why, at first, all the variety of methods of remote work was reduced to conducting lectures and seminars in the form of webinars, as, for example, at the Novosibirsk State Technical University (NSTU).
However, if the webinars helped students and teachers of the humanities, then for technical and information specialties this was not enough for the following reasons: 1) firstly, in order to write mathematical formulas, as well as draw drawings and diagrams, the teachers did not have a corresponding blackboard at home, moreover, it turned out that many students did not have webcams at home; 2) secondly, the lack of necessary technical means has led to the fact that practical training on problem solving has become virtually impossible to conduct. If the performance of laboratory work (not requiring special equipment, but only computers, such as at the business faculty of NSTU), which by definition require independent work of students, could be supported by sufficiently developed methodological support and supplemented with video tutorials from the Internet on key points of the topic under consideration, then the process of solving problems for teachers could not be controlled either in content or in time; 3) third, even when creating tests (which were overwhelmingly used by teachers), it was necessary to look for such information tools that, on the one hand, would make it relatively easy to pack test questions and tasks with multimedia tools for a sufficiently deep understanding of their economic or physical meaning by the student, and on the other hand, to control and limit the time for their implementation; 4) fourthly, information and tools for creating electronic tests should automate the process of checking and evaluating completed tests, in order to reduce the time for their processing, since, ultimately, there is only one teacher, and there are many students; 5) fifth, the information tool for creating electronic tests should interact well with MS Office programs, which for the vast majority of teachers are a working tool for creating methodological support for the educational process.
All the above reasons became the basis of the system of requirements for various software products in order to choose among them an information tool for creating electronic tests and solving practical problems in remote mode in the direction of training 38.03.05 "Business Informatics" at the business faculty of NSTU in the spring and autumn of 2020.

Using the iSpring Suite Platform
After installing the iSpring Suite 9.7.9 distribution, this product can be used as a universal learning platform both offline (see figure 1) and as a separate tab in PowerPoint. The formation of questions, tasks, and test properties is presented below in the following sequence of operations: 1) select a question option, as shown in figure 2;   Fig. 2. Select a question option.
2) the question using a numerical answer is shown in figure 3  in the "Feedback and branching" section of figure 3, you can configure the response rating: true -4 points, incorrect -0 points; repeated -minus 2 point;  in the section "Slide properties" you can limit the response time;  on the Insert tab of the menu ribbon, you can insert multimedia elements into the question text using the corresponding buttons; 3) the question created using mathematical formulas is shown in figure 4;  in the "Feedback and branching" section of figure 4, you can configure the response rating: true -2 points, incorrect -0 points; repeated -minus 1 point;  in the section "Slide properties" you can limit the response time;  on the Insert tab of the menu ribbon, you can insert multimedia elements into the question text using the corresponding buttons;  properties for automatically sending test results immediately after completion to the teacher's email address with the ability to demonstrate correct and incorrect student responses (see figure 8); 5) the result of forming the test with all its questions, rules, ratings and publications is recorded in the corresponding .html file, which is stored in the folder defined in the properties of its publication when you click the "Publish" button on the program menu ribbon. The teacher sends the test file to students, which, when opened, is displayed in the browser with the specified properties: 1) the first page is displayed (created in the test data generation mode), where the student must enter their data (figure 9), which will be included in the test result when sent to the teacher's email: Fig. 9. The first page of test.
2) when you click the "Start test" button, a slide opens with the first question of the test and in the upper-right corner, the timer for limiting the time for all answers set in the properties is turned on (see figure 10) 3) if the answer is incorrect, a retry notification appears (see figure 11), if this property was set when setting up grades; if the answer is correct, a corresponding notification appears and an invitation to continue running the test (see figure 12) Fig. 11. The answer is incorrect.

Conclusion
The results obtained in item 4 show the possibility of conducting remote classes on the iSpring Suite platform. In addition to creating and conducting electronic tests, this platform was used when students performed homework and control work in the form of solving problems with remote access, when it was necessary to give not only the correct answer, but also to present the entire course of solving the problem. At the same time, the results of the solution were automatically sent to the teacher's email address in the same way as when performing tests. In general, the experience of conducting classes in remote mode on the iSpring Suite platform can be considered successful and it is mandatory to use it at the remote department of NSTU, as well as if students cannot attend face-to-face classes for good reasons.
