KNOWING REAL OOP WITH DELPHI
An opinion prevails that pupil, who developed in Delphi a simple visual application, learned OOP basics. It is wrong of course. The article proposes a method how OOP ideas can be really demonstrated using possibilities of Delphi environment. For this purpose a simple and descriptive task was carefully selected and particularly developed — it is an indicator of integer number’s value similar to the display of modern electronic device.
Keywords: OOP, learning, teaching, Delphi, informatics course.

THE EDUCATIONAL GAME “MATHEMATICIANS VS PROGRAMMERS”
The article describes the educational game that matches “Mathematicians vs programmers” subject area of the Federal State Education Standards. The game is targeted on schoolchildren which are interested in mathematics and programming. It promotes development of motivation, formation of intersubject communications and mastering of collective work skills.
Keywords: IT and mathematical education, gaming technologies, computer technologies in mathematical education.

CREATING VIDEO PUZZLES ON YOUTUBE
The article describes one of the ways of involving schoolchildren in creating a video on a computer. As a software platform the YouTube Video Editor is selected. An example of creating a video is shown and the manual on creating video puzzles is given.
Keywords: video puzzle, training, video hosting, animation, multiplication.

FEATURES OF METHODICS OF TEACHING ON ROBOTICS IN RURAL SCHOOLS DURING THE SHORT-TERM COURSE
The article describes the problems of developing methodics of teaching students on robotics through the short-term course based on Arduino and LEGO MINDSTORMS. The results of approbation of such course at the four-day children’s camp “TechnoYunost” are presented in the article.
Keywords: robotics, network cooperation, Arduino, LEGO MINDSTORMS.

ORGANIZATION OF PROJECT AND RESEARCH ACTIVITY OF SCHOOLCHILDREN BY MEANS OF EDUCATIONAL ROBOTICS
The Federal State Educational Standards establish requirements to results of the students, one of which is possession of skills of educational and research and project activity. Robotics is the efficient instrument of involvement of children in scientific and technical creativity. The description of substantial and procedural aspects of a course of educational robotics as resource of the organization of project and research activity of school students is provided in the article.
Keywords: informatics, project and research activity, educational robotics, LEGO-constructioning, object-oriented programming.

PRACTICAL WORKS FOR CREATING ANIMATION IN LAZARUS
The article presents examples of practical works in the Lazarus programming environment that allow students to learn both the basics of algorithmization and programming and the basics of creating animation.
Keywords: Lazarus, branching, animation, interactive programming.

PROPAEDEUTICS OF PARALLEL COMPUTING IN SCHOOL INFORMATICS. PARALLEL FORM OF THE ALGORITHM IN GRAPH TRAVERSAL TASKS
It is proposed to use the tasks of building/bypass “labyrinths” to learn the concept of “parallel form of the algorithm (multilevel structure)”. As an example the investigation of task from the contests “TRIZformashka-2015” is given.
Keywords: informatics, secondary school, primary school, teaching methods, parallel algorithms, parallel form of algorithm, multilevel structure, graph traversal, parallel computing, propaedeutics, TRIZformatics, TRIZformashka.

CLASSIFICATION OF LEARNING TASKS ON INFORMATICS DEPENDING OF COMPLEXITY LEVEL
The article describes a method for classifying learning tasks on informatics. The classification is based on the taxonomy of D. Tollingerova and the system-structural analysis of the learning task of L. M. Friedman. The proposed classification takes into account both the cognitive complexity of the task and its structural complexity and describes the three levels of complexity of learning tasks on informatics. The notion of a methodically important task is introduced, examples of classification of tasks on the topic «Introduction to the algebra of logic» are given.
Keywords: learning task, classification of learning tasks, cognitive complexity of task, structural complexity of task, methodically important task, Tollinger taxonomy, informatics, classification of logical tasks, level of complexity of task.

TOMOGRAPHY = INFORMATICS + MATHEMATICS + PHYSICS + BIOLOGY
The article proposes a laboratory work at the intersection of informatics, mathematics, physics and biology: modeling the work of a medical tomography and studying tomography on a four-dimensional object.
Keywords: X-ray, tomography, function of one, two and three arguments, computer graphics, Maple, Mathcad.
