METHOD OF CONSTRUCTION OF 3D MODELS OF RIGID OBJECTS ON ONE IMAGE AND ITS APPLICATION IN PROJECT ACTIVITY OF SCHOOLCHILDREN
A simple technique for constructing 3D models of ground surface objects from a single space image is proposed. The method gives an estimation of the model from the reference object, for which the value of the height corresponding to the given segment on the image giving the altitude coefficient in the spatial neighborhood of the object is known, i.e. scaling coefficient along the axis of the applicator. The altitude coefficient varies with time, i.e. from snapshot to snapshot, which allows to evaluate models of objects of different clarity, from low to high, using the space-time neighborhood of the reference object. With a distance from the standard, the altitude coefficient is continuously changing, which makes it possible to estimate the height of a distant object by “moving” the calculations through a chain of closer objects connecting the source and the final. Using an alternative “calculation by shadow” allows us to estimate the model when photographing the terrain in the nadir, i.e. in the absence of visibility of the side parts of the design object. In view of the availability of practical application of this methodology in the general education system, a number of project works of schoolchildren in the field of 3D modeling based on space images data.
Keywords: landfill, dump, 3D model, 3D modeling, economic zone, building, rigid object, Sketch Up, height, scale factor, Google Earth, project work.

FORMING METASUBJECT SKILLS AT INFORMATICS LESSONS ON THE BASE OF THE STRUCTURING OF THE EDUCATIONAL TEXT
The possibility of using the structuring of the educational text for metasubject skills forming is considered in the article. The example of the informatics lesson on the theme “Control and cybernetics” for the 9th grade is given. At the lesson students are encouraged to use the adapted educational text, structure it and compile its model.
Keywords: metasubject approach, structuring, educational text, text model.

USING FREEWARE IN THE EDUCATIONAL PROCESS AS A FACTOR OF SPIRITUAL AND MORAL EDUCATION OF STUDENTS
The article examines the influence of the choice of the type of software used in the educational activities of the educational organization, on the spiritual and moral education of students. Particular attention is paid to the need for the formation of a free individual who can make an independent, competent, qualified choice in the field of software and be responsible for the consequences of the decision.
Keywords: freeware, spiritual and moral education, freedom.

THE DEVELOPMENT OF ALGORITHMIC THINKING OF STUDENTS ON THE BASIS OF MENTAL-EXPERIENTIAL TRIT-TASK
The article discusses the features of using the computer algebra system Maple for demonstrating the operation of encryption algorithms in the process of studying the protection of information in the school informatics course. The programs that allow encryption and decryption of texts using various historical ciphers are given.
Keywords: encryption, decryption of text, Maple.

THE DEVELOPMENT OF ALGORITHMIC THINKING OF STUDENTS ON THE BASIS OF MENTAL-EMPIRICAL TRIT-TASKS
The article substantiates the effectiveness of using mental-empirical trit-tasks in the study of the theme “Algorithmization” in the school course of informatics. The leading idea of the trit-task lies in its formulation in the sensory, model (cognitive) and conceptual forms. The article presents the procedural structure of thought operations in the compilation of algorithms, gives examples of trit-tasks for the study of basic algorithmic constructions.
Keywords: algorithmic thinking, mental schemes, algorithmization, school course of informatics.
