SOFTWARE INSTRUMENTS FOR PRESCHOOL AND PRIMARY SCHOOL EDUCATION IN INFORMATICS

Lowering the age of introducing a propaedeutic course on the basics of informatics for younger schoolers and preschoolers is an important contemporary task for modern pedagogy. The article describes the features of the operational style of thinking and the history of educational tasks in the propaedeutic school course of informatics. The requirements for curriculum and task classification are discussed. The approach to the assessment of students’ activities, based on collective and individual competitions tournaments is proposed. Some examples of the sequence of educational and test tasks are given. The instrumental and conceptual proximity of training and test assignments made it possible to use for their design unified interface requirements that were tested in the long-term practice of training and control tasks of the propaedeutic course.
Keywords: propaedeutic course, distance learning, assessment, school Olympiads.

USING INFORMATION TECHNOLOGIES FOR THE ACQUAINTANCE OF STUDENTS OF SECONDARY SCHOOL WITH THE THEME “SET”

The article describes the continuity in teaching the elements of the set theory on the levels of preschool, primary general and basic general education. The relevance of studying the theme “Set” is grounded. The result of the analysis of educational and methodical literature on this theme is described, showing that in the basic school at the proper level neither the definifions nor the ideas of the set theory are stated, which entails the students’ difficulties in mastering this theme. In this regard, to improve the efficiency of the study, it is proposed to use the Maplet-applications developed by us using Maplets library of the system of computer algebra Maple: “Union of two sets”, “Intersection of two sets”, “Difference of two sets”, “Symmetric difference of two sets”, “Addition of one set to another”. These Maplet applications allow to interactively perform basic operations on sets, control students’ knowledge of the order in which these operations are performed, and can be the starting point for solving more complex set theory problems.
Keywords: mathematics, informatics, information technologies, basic general education, set, set operations, Maple, Maplets, Maplet.

MOBILE TECHNOLOGIES FOR EDUCATIONAL PROCESS: EXPERIENCE OF USING ONLINE SERVICES

The concepts of mobile technologies in the educational process are discussed in the article. It provides an overview of Internet services that allow students to use their mobile devices in the learning process. It is concluded that the described web services and mobile devices can be recommended for use in the organization and conduct of rapid testing of student’s knowledge and to simplify the visual demonstration of the studied material.
Keywords: Internet service, mobile technologies, secondary professional education, Web 2.0, BYOD, GYOD.

JOURNEY INTO THE WORLD OF SCIENCE AND ART ON A PLANTIGRADE MACHINE

The article shows how the computer mathematical program Mathcad allows to solve mechanics problems, in particular, kinematics problems by a new method. The procedure for optimizing the parameters of the Tchebyshev plantigrade machine is described — the calculation of the lengths of its parts, so that the machine will move without vertical pushes. A technique of hybrid solution of mathematical problems on a computer is discussed, where analytical (symbolic) and numerical methods are used alternately or in parallel. A new trend in visual arts is presented, associated with the representation of the trajectory of the motion of kinematic devices.
Keywords: plantigrade machine, optimization, Mathcad, kinematic devices, visual art.
