Mathematical modeling of pipes production forecast based on polynomial regression analysis (PRA)

The paper analyzes some indicators of the production activity of Ukraine’s metallurgical plants, which are under the auspices of Ukrtruboprom association for May-August 2022. Mathematical modeling of pipe production process forecast based on polynomial regression analysis was performed. The presented mathematical models provide adequate results for predicted indicators of economic activity of enterprises selected for analysis. The Russian military operations’ negative impact on the hostilities’ conduct in Ukraine is shown

HOW TO BUILD TESTS IN THE IMITATION MODEL FOR TEST-BASED KNOWLEDGE CONTROL

The principles of imitation model for knowledge test control, specifically on the perfection of the procedure of constructing a test, are developed in this model. The authors suggest taking into account the difficulty of the question when one is making a decision about including a given test question into the test. They also suggest using iterational calculations in order to create a test with the help of optimization algorithms that are used for the process of random searching. The sum of task complexity indices for such test will meet the criteria of joint value and difficulty. Detailed explanation of mathematical apparatus that is used for decision-making during the test-building process is given in the article as well as an example that demonstrates main steps of iterational calculations and mechanisms for achieving optimal test structure based on the criteria of joint value and difficulty

THE USE OF ANIMATION AS A MEANS TO INCREASE MOTIVATION AMONG STUDENTS OF ENGINEERING DISCIPLINES

The study of the principles of action and technical objects design at high levels of abstraction presents considerable difficulties for engineering students and, as a result, reduces their motivation for learning. Drawings, diagrams, general types of technical objects, that are crucial to gaining understanding of how complex mechanisms operate, can be easily converted into digital format. However, their use to increase the motivation of students for learning is hampered by insufficient theoretical groundwork and limited experience in the introduction of animated graphic materials. The analysis of publications on the subject of the article confirms that the use of information and communication technologies can improve the quality of teaching in higher education institutions, including by enhancing students' motivation for learning. The aim of the study was to determine the impact of animation on the correlation between internal and external motives in the course of educational activity of students majoring in engineering. The article describes the framework developed by the authors for creating animation of a technical object model and its perception by the students in the context of increasing motivation. Three levels of animation (low, medium and high) are classified according to the degree of realism of the designed models of technical objects. The findings reveal that the control of animation at each level of realism makes it possible to transform it into a game situation and enhance the practical skills of managing the object. The authors have carried out a comparative analysis of the influence of animation on the motivation of students of engineering majors. The experimental testing has identified a statistically significant change in the ratio between internal and external motives, determined the level of motives associated with acquiring knowledge and skills, gaining engineering qualifications and formally obtaining a degree after graduating from a higher education institution
