ABOUT THE PROBLEM OF CLASSIFICATION OF THE CONCEPTS OF INFORMATICS STUDIED AT SECONDARY SCHOOL

The article raises the problem of classification of the concepts of computer science and informatics studied at secondary school. The efficiency of creation of techniques of training of pupils in these concepts depends on its solution. The author proposes to consider classifications of the concepts of school informatics from four positions: on the cross-subject basis, the content lines of the educational subject “Informatics”, the logical and structural interrelations and interactions of the studied concepts, the etymology of foreign-language and translated words in the definition of the concepts of informatics. As a result of the first classification general and special concepts are allocated; the second classification — inter-content and intra-content concepts; the third classification — stable (steady), expanding, key and auxiliary concepts; the fourth classification — concepts-nouns, concepts-verbs, concepts-adjectives and concepts — combinations of parts of speech.
Keywords: methods of teaching informatics, technique of training in informatics, classification of concepts, concepts of school informatics, general educational concepts, special concepts, inter-content and intra-content concepts, stable concepts, steady concepts, expanding concepts, key concepts, auxiliary concepts, concepts-nouns, concepts-verbs, concepts-adjectives, concepts — combinations of parts of speech.

ASSEMBLING THE RS FLIP FLOP ON CHIPS CONTAINING ELEMENTS OF “OR-NOT”, “AND NOT”

The article provides general information about flip-flops, their types, about an asynchronous RS flip-flop. A detailed description of the practical work on assembling the RS flip-flop in two variants is given, based on a chip containing four “2OR-NOT” elements, and based on a chip containing four “2AND-NOT” elements. The details from the electronic set “Micronik” (“Amperka”) and the details provided by the site “Let’s create together” are used in assembling.
Keywords: trigger, flip-flop, RS flip-flop, toggle switch, relay, chip, truth table.

DESIGNING E-LEARNING RESOURCES FOR TEACHING MATHEMATICS IN PRIMARY SCHOOL WITH ADOBE FLASH AND HTML5 SYSTEMS

In the modern educational space regarding the realities of the information society special importance is attached to issues related to the provision of a high level of informatization of education, which implies teachers’ mastering the necessary competencies and the ability to introduce e-learning resources into educational and training practice. Adobe Flash as one of the platforms for creating web applications and multimedia presentations enjoys greatest popularity with users including teachers. However, in connection with the announcement of discontinuing Adobe Flash support in 2020, the issue of choosing an analog to create web applications and presentations for use in teaching purposes is becoming particularly relevant. The article provides a comprehensive analysis of developing electronic educational resources by teachers using Adobe Flash and HTML5 for teaching math in primary school.
Keywords: designing interactive educational applications, Adobe Flash, HTML5, future primary school teacher.
