Abstract: The object of this research is the process of teaching mathematics. The subject of this research is the strategy of teaching. The author suggest and examines the internal algebraic perception of teaching strategy viewed as the mechanism for creating the teaching plan. Earlier on, Y. B. Meknikov has proposed the interpretation of algebraic approach towards modelling as the system consisting of three components: 1) system of basic models; 2) system of typical transformations and standard combinations of models; 3) approximation mechanism intended for a similar understanding of the model in form of a result of typical transformations and standard combinations of basic models. The internal algebraic understanding of the strategy is distinguished by the fact that basic elements represent the components of the strategy, rather than the external perception, where the basic elements are a part of other strategies. The research carries a theoretical character, though some of its results have already been implemented into educational practice in the Ural State University of Economics. The theoretical framework relies on the modelling theory of Y. B. Melnikov, which is based on the formal-constructive interpretation of the model. The scientific novelty primarily consists in structuring of model of the strategy as a mechanism for creating plan of action, as well as distinction of the postulates of strategy that help to define the typical transformations and standard combinations of the plans of action. The author proposes an internal algebraic approach towards the concept of strategy, where the algebraic concept means a system consisting of three components: a) system of basic elements; b) system pf typical transformations and standard combinations of the elements; c) approximation mechanism intended for understanding of strategy in form of a result of application of typical transformations and standard combinations of the basic elements.

Abstract: The object of this research is the process of teaching mathematics to the economists and engineers. The subject of this research is the formation of skills for comprehensive and multilateral assessment of adequacy of the phenomena under consideration in the process of teaching mathematics to the economists and engineers. The goal of this work lies in structuring the model of multilateral assessment of mathematical activity (its objectives, methods, and results) and the application of mathematics as the component of economic and engineering education. The authors suggest the multi-criteria approach towards assessing the indicated phenomena on the basis of the original theory of modelling and theory of adequacy. The estimation of quality of the model in the theory of adequacy is defined via comparing the assessable model with the stated reference model. Research methodology includes the theoretical analysis of the modern mathematical education, theory of modelling, competence and activity approaches. In Y. B. Melnikov’s theory of modelling, the estimation of adequacy of the model is viewed as a result of comparison of the assessable and reference models. Evaluation of adequacy is viewed as a function, which arguments are the assessable and reference models. This allowed acquiring new scientific results: formalization of a specific attribute of adequacy can begin either with the structuring of reference model (with further concretization of the corresponding functions), or with the formation of the comparison method (with further determination of referenced model and formalization of the corresponding function).

Abstract: The subject of this research is the process of creating a work plan using the methods of bottom-up and top-down analysis. The authors based upon the hypothesis that every point of planning by the executive and planner is perceived either as a reference to a known algorithm of actions, or as a goal setting for work without concretization of means of achieving it. The goal is being viewed as a system of example models of results meant for planning and assessment of adequacy of results, both planned and achieved. The research carries a theoretical character and employs results of research in the area of management, modeling theory of Y. B. Melnikov, which is based on formal-constructive interpretation of the model and analysis of management decisionmaking process. Authors examine the process of transformation of the original plan, consisting of a single point (formulation of goal), towards a plan of which all main points are perceived by the executive as references to known to him algorithms of actions. The authors’ original interpretation of the methods of bottom-up and top-down analysis is schematically illustrated by the examples from the taxation practice.

Abstract: The object of this research is an important and relevant question of modern education – the realization of educational activity with application of the information and communication technologies. The subject is the assessment of the quality of math classes with application of the information and communication technologies. Special attention is given to the development of mechanism for creating the system of models considered as exemplary for the math class (content area, presentation style, etc.). The article describes (from various perspectives) the criteria for the system of exemplary models that allow assessing the quality of the content of math class. Methodology of the research is based on the modelling theory. The following conclusions were made: 1) the content of math class, developed with implementation of the formalized system of exemplary model, produces the more extensive pedagogical effect that the content selected by certain private methods; 2) the described system of exemplary models can be used not only as an apparatus for assessing the quality of the existing mathematical content, but also as instrument of projecting the new math disciplines; 3) the suggested approach can be applied to the assessment of quality not only of the mathematical educational content, but also other areas of education. Unlike the existing studies on the questions of application of the information and communication technologies in math education, the accent is made not on the quality of content solution, but rather the quality of the content of math classes. The proposed approach allows harmoniously combine the unification and diversification of presentation of the educational discipline, as well as ensure to the student a possibility of structuring of an individual educational trajectory.
