Based on the ideas of the psychological and pedagogical concept related to the description of the creation of conditions for the gradual deepening and expansion of knowledge, skills and abilities of the future teacher in the direction of professionalization, special attention is paid to the founding of the participants in the educational process of the ability to work in a digital environment. The stages of founding such a skill are illustrated by examples of projects completed by students at certain stages of university education. As one of the examples, the structure of a digital teacher’s room, implemented in one of the schools in the city of Perm, is given. In general, the presented content allows us to state that the advantage of the ideas of translating into practice the continuous training of mathematics teachers in the context of the digital transformation of education, noted by the features described by the authors, is their multiplicativity, which implies the possibility of implementation in any region of Russia and in neighboring countries, as well as replication not only in the educational sphere, but also in other areas of human activity. The article can be useful both for students enrolled in the direction of “Pedagogical education” and for specialists in the field of teaching staff training.","PeriodicalId":45270,"journal":{"name":"Informatics in Education","volume":"24 1","pages":"20-32"},"PeriodicalIF":2.7,"publicationDate":"2021-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87688330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The only one course in Russian — “Web accessibility in e-learning” (Stepik platform) was detected. The following positions presented on MOOCs’ promo pages were analyzed: platform, author, target audience, duration of training, access (open / closed), cost, student’s achievement document (certificate / badge / other); training mode (independently / with instructor / other); prerequisites (starting skills). An average MOOC “portrait” in the field of web accessibility has been formed: target audience — web developers/web designers (45 % of MOOCs) or developers/teachers of online courses (24 %); prerequisites — not required (76 %); achievement document — certificate for an additional fee (55 %); platform — Coursera (26 %), Canvas (24 %) and EdX (21 %). The content of the nine MOOCs available for study was analyzed in detail. It was shown, that the content of MOOCs on the web accessibility in e-learning can vary and have different depth depending on the target audience of students, but it must include: concepts of web accessibility and universal design in learning and related WCAG guidelines; web content accessibility assessment methods; methods for developing accessible online materials.","PeriodicalId":45270,"journal":{"name":"Informatics in Education","volume":"32 1","pages":"38-46"},"PeriodicalIF":2.7,"publicationDate":"2021-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79980454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since September 2018, the course has been held in all preparatory groups of all kindergartens in Surgut — more than 6,000 children annually. The educational and methodological kit for the course, including the digital educational environment PiktoMir, is freely distributed and can be downloaded from the SRISA RAS website for use for any purpose, including commercial. The course “Algorithmics for preschoolers” discussed in the article is the first part of the long-term course “The basics of programming for preschoolers and junior schoolchildren” being developed. The course uses a textless programming technique. The child composes a program from pictograms with robot commands, singleletter names of subroutines and pictograms of control structures. At the initial stage of training, a screenless technology for compiling a program from material objects is used. The proposed technology favorably differs from analogues in the world in that when working with PiktoMir, a program in the material world can be composed of material objects freely movable by a child: cards, cubes with printed or hand-drawn command pictograms. Information about each command of the program is extracted exclusively from the image perceived by the child, and not from any machine-readable graphic codes or electrical codes hardwired into the material carrier of the pictogram. The child “photographs” pictograms with his tablet, on which they are recognized using neural networks by a special PiktoMir module.","PeriodicalId":45270,"journal":{"name":"Informatics in Education","volume":"57 1","pages":"28-40"},"PeriodicalIF":2.7,"publicationDate":"2020-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85672233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the context of “indicator — assessment”, the required standard of student behavior in the process of performing team activities was determined. Invariant indicators are used to assess the teamwork competency, regardless of the role played by the student. The invariant indicators are indicated: understanding the importance of the task for the team's activities, the distribution of roles in the team, team interaction, the assessment of the teamwork. To determine the variable indicators, an analysis of the existing methods for the distribution ofcommand roles was carried out, the types of activities of an IT specialist were studied. To solve problems related to the implementation of activities for the design, development and maintenance of software tools within the framework of teamwork, it is advisable to distinguish six roles: analyst, innovator, negotiator, designer, executor, coordinator. Based on these roles, variable indicators are defined. The division of indicators into invariant and variable implies different requirements for the level of development. Invariant indicators must be mastered by all, while variable indicators allow for partial mastering in some indicators. The use of the system for assessing the teamwork competency will reveal potential problems in the preparation of a future IT specialist, clearly define the directions of the student's development, and form recommendations for him regarding professional activities.","PeriodicalId":45270,"journal":{"name":"Informatics in Education","volume":"121 1","pages":"20-27"},"PeriodicalIF":2.7,"publicationDate":"2020-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74941338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within the framework of subject learning, digital technologies are radically changing the content of the disciplines taught and the form of their presentation. The experience of creating a digital educational environment (DEE) in the framework of subject training is considered on the example of basic geometric and graphic training (GGT) of technical university students. Currently, the main factors shaping GGT are the paradigm of engineering education and methodology of design and development activities, which have undergone dramatic changes with the development of information technology. The basic concept of graphic education should initially and entirely be based on a digital 3D (volumetric) model that combines information about a product at all stages of its life cycle. At the same time, applied geometric aspects should prevail over abstract geometry and graphics, not underestimating the role of theoretical foundations in the basic GGP. The architecture of building DEE of geometric-graphic training is presented, which integrates all types of educational activities and is based on the principle of “continuity” of the learning process in a digital environment at all stages of the educational process. The functional use of digital technologies in various forms of training sessions, which allows students to carry out independent activities, taking into account personalization, is noted. Practical examples of graphic tasks, design and test tasks are given. When organizing monitoring in DEE conditions, existing methodological developments can be used, adapted and integrated in terms of the DEE system and the paradigmatic concept of GGT. Monitoring of learning outcomes in assessing digital competence, along with the constant improvement of test control, implies its completion with other forms of assessing the achievements of students.","PeriodicalId":45270,"journal":{"name":"Informatics in Education","volume":"118 1","pages":"53-63"},"PeriodicalIF":2.7,"publicationDate":"2020-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77425228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The introduction and use of gamification in the automation of these processes is proposed in order to increase the indicators of motivation, retention and involvement of personnel. Practical examples of the application of this tool in innovative companies are given. The mechanics of collaboration (cooperation), promotion, progress, appointments, and competition are analyzed the point of view of their effective application in corporate personnel management systems. It is proposed to use a competency-based approach to identify the knowledge, skills and abilities that a particular employee lacks and the efforts of managers of any company should be directed to the development and acquisition of which. A model of finite automaton is described, the development of which is crucial to formalize the processesunder consideration, analyze them, search for problem situations, modify, design information systems for monitoring and managing personnel training. Game mechanics are considered from the event approach point of view, the development of a certain game mechanics reaction in case of a certain event. In this case, the process of passing the training course can be represented as a finite deterministic automaton. The main task of developing the game mechanics reaction is to encourage the user to perform actions that will bring his current state closer to the final one. It is concluded that the use of gamification reduces the amount of routine actions necessary for the implementation of training, adaptation and development of personnel, make them more transparent and understandable for both employees and the company, minimize the time to implement these processes and, as a result, reduce their cost.","PeriodicalId":45270,"journal":{"name":"Informatics in Education","volume":"16 1","pages":"28-37"},"PeriodicalIF":2.7,"publicationDate":"2020-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88285127","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
