Computational thinking (CT) is built on the foundation of these abilities. The authors contend that the employment of specialized digital tools promotes the development of computational thinking and that purposeful creation of computational thinking improves teachers' and students' digital competence. The concept of CT, as well as existing definitions and components, are examined in this article. <br>A list of courses from various countries' curriculum on which CT is studied in primary school is provided. The importance of CT as a fundamental talent for everyone is underlined, and it should be developed through the integration of several disciplines to solve problems. The link between the CT components and the key competencies that should be instilled in kids as part of the primary education curriculum. <br>The findings of a survey of more than 60 primary school teachers from various regions of Ukraine about their understanding of the concept of computational thinking and their experience in the development of skills related to all components of computational thinking in primary school students are presented. A review of open educational resources from around the world is offered to assist teachers in enhancing students' CT skills. The strategy for putting the CT development concept into practice for future teachers and primary school teachers is offered, taking into account the ability to employ specific digital tools.</p> Nataliia V.

The authors' curriculum simulation technique, which uses Petri nets, is shown. Some didactical foundations of curriculum design and academic discipline structure, as well as the theoretical basics of Petri nets in terms of their considerable facilities for multiple processes synchronization, formed the theoretical framework that allowed us to develop the technique. The technique of academic disciplines structuring based on the frame model of knowledge representation is described as a series of processes that culminate in a net of disciplines modules (frames) that include the appropriate learning materials while preserving and propagating links between them. The practical-driven approach to curriculum modeling based on Petri nets simulation is offered to tackle the problem of synchronization of learning elements mastery across academic disciplines with regard to the established links in the frames. The many types of precedence relations for the learning elements (frame inputs and outputs) were identified. Using these precedence relations, we were able to model a learning element and the process of mastering it using Petri nets. We were able to create a model of a curriculum discipline module and, eventually, a curriculum discipline model using Petri nets modifications and learning element connections of various types. All of the evolution of the learning elements mastering by students in the curriculum courses is represented by built Petri nets models. The rules of Petri net execution and alterations ensure that their mastering is synchronized. The advantages and disadvantages of the proposed technique are discussed. The advantages of using such a simulation to create a synchronized curriculum for IT-specialist training are outlined. The research's potential are presented in terms of applying the findings to the development of specialized software.</p> Lyudmyla I. Bilousova, Liudmyla E. Gryzun Copyright (c) 2022 Lyudmyla I.

For teaching purposes, a statistical model for simulation of null hypothesis significance testing was created. The results were analyzed using Fisher's angular transformation, Chi-square, Mann-Whitney, and Fisher's exact tests. Appropriate software was created, allowing us to recommend new illustrative materials for expressing the limitations of the tests that were examined. Learning investigations as a technique of comprehending inductive statistics has been proposed, based on the fact that modern personal computers can run simulations in a reasonable amount of time with great precision. The collected results revealed that the most often used non-parametric tests for small samples have low power. Traditional null hypothesis significance testing does not allow students to analyze test power because the true differences between samples are unknown. As a result, in Ukrainian statistical education, including PhD studies, the emphasis must shift away from null hypothesis significance testing and toward statistical modeling as a modern and practical approach of establishing scientific hypotheses. This finding is supported by scientific papers and the American Statistical Association's recommendation.</p> Oleksandr H. Kolgatin, Larisa S. Kolgatina, Nadiia S.

It has been demonstrated that the implementation of the higher education standard for SE bachelors has generated a number of issues in terms of ensuring training quality, principally due to a lack of specification for both skills and learning outcomes. Designing a precise framework of professional competencies for SE bachelors is one method to overcome these issues. The research examines methods for developing K14 (the ability to participate in software design, including modeling (formal description) of its structure, behavior, and working processes), a critical particular professional competency for future software engineers. Recommendations for software design teaching techniques, learning content, modeling and design tools, and assessment of the level of formation of relevant competence are developed based on a historical and genetic review of software design training among SE students in the UK, USA, Canada, Australia, New Zealand, and Singapore. The industrial-style software design training (studio training) is used as an example. The transition from architectural to detailed design, as well as project implementation, are discussed. The study's future prospects include substantiating the third engineering component of SE – software construction (after requirements engineering and design engineering).</p> Andrii M.

AR technology, according to a review of numerous publications, provides new options for teachers and makes learning more appealing to pupils of all ages. Students can use mobile AR apps to observe a real-world environment with virtual things layered or composited on top of it. This is especially true for young children. The article highlights the activities that allow a child to have a unique AR experience. There is a comparison of available augmented reality (AR) applications for learning the alphabet. The author describes a novel augmented reality application that was created with Unity, C\#, and Vuforia. The developed mobile AR application allows students to learn the Ukrainian alphabet, number names, and animal sounds. The learning process is enhanced by three-dimensional visualization and sounding of each letter and number thanks to this program. An analysis of a survey of teachers and parents found that utilizing an AR application greatly boosted children's motivation and self-efficacy in learning letters and numbers. The AR application aided in the retention of the child's attention while learning new content by speeding up the process of memorization.</p> Olena Ie. Piatykop, Olha Pronina, Iryna B.
