    Application of the Cobb-Douglas function for the formation of would-be economists' analytical skills
    (2025) Vlasenko, Kateryna; Armash, Tetiana; Achkan, Vitaliy; Kaluhin, Ruslan; Bohdanova, Nataliia
    Training high-quality specialists in the economic eld is crucial. This task can be achieved by training students in economic specialties in mathematical modeling. Solving problems using production functions, particularly Cobb-Douglas functions, can become the ground for mastering mathematical modeling. The article looks into the issue of the combination of table and clustering methods to systematize such kinds of problems. The involvement of students in real production situations while mathematical training contributes to the development of analytical skills needed for analyzing economic processes, modeling decisions, working with data, and coming to conclusions. The article presents a system of problems involving the Cobb-Douglas production function. The study shows the implementation of these problems while mastering `Multivariate Functions' by economic majors. Also, the work presents the practicality of such a system when developing their analytical skills. The run experiment con rmed that the developed system of problems results in the progression of wouldbe economists' analytical skills.

    UI/UX design of educational on-line courses
    (2022) Vlasenko, Kateryna; Lovianova, Iryna; Volkov, Sergii; Sitak, Iryna; Chumak, Olena; Krasnoshchok, Andrii; Bohdanova, Nataliia; Semerikov, Serhiy
    This paper considers the problem of an interface for educational platform, which is fully effective for achieving the outcomes of educational activity. The current research is a theoretical analysis of existing recommendations on UI/UX design, applied when creating educational systems, as well as of research papers that study user interface (UI) usability and evaluate user experience (UX) in designing on-line platforms. This article describes a mechanism for evaluating usability with the help of baseline and final evaluation tool. It also studies UX components, that ensure its high quality. A list of standard components of web-design is being discussed in the present paper; modern trends in web-design of educational platforms are identified. The paper provides the description of an on-line course model, which is built on the basis of analysis of the prerequisites for existing and functioning of educational on-line systems and which is aimed at achieving outcomes of educational activity. There is ground to believe that the design of educational on-line courses will contribute to achieving the outcomes of educational activity, if user interface components comply with a list of criteria, such as easy-to-perceive content, no extra information, easy and simple navigation on the pages of the course, following the principles of usability.

    Using the case method while training would-be mathematics teachers
    (2025) Achkan, Vitaliy; Vlasenko, Kateryna; Chashechnikova, Olga; Bohdanova, Nataliia; Protsyk, N.
    The article looks into the issue of developing a methodology for using the case method in mathematics teacher training. The study proposes and substantiates the components of using the case method in teaching the methodological disciplines of the would-be mathematics teacher: motivation of educational activity, goal setting, content, methods, forms, and means of learning. Motivation for learning using the case method is provided by modeling the teacher's real professional activity while considering methodological problem situations (cases). To ensure goal setting, an algorithm for case selection is proposed and illustrated depending on the goal of the educational curriculum or the goal of a speci c educational class. The research method is the case method, implemented through work with a system of cases for methodological disciplines. The content of the cases covers all modules of the methodological discipline curriculums. Forms of training depend on the types of cases used in the class. Examples of cases of all kinds are proposed, suitable for use within frontal, group, and individual work. Learning means include multimedia presentations, video cases, dynamic mathematics packages, and educational cloud services. The run experiment con rmed the practicality of using the developed methodology when training would-be mathematics teachers for professional activities.
