MODELING A TASK ON PERCENTAGE IN VISUAL INFORMATIONAL FIELD
In this paper we consider the application of conception visual informational field during the process of teaching mathematics by the example of problem solving situation on the percentage. Visual informational field is a method of representation of information on the plane, which accessible for visual perception and able to form various models as methods of representation of information. Problem solving represents a modeling in visual informational field based on the system approach, acting as an instrument of informational organization and simultaneously as a learning tool. During the problem solving a student makes a conversion of information as a coherent transition from one model of visual informational field to another one: from a text of problem situation in the formalized text (text model), next in the system of images and signs (image and sign model), then he reveals the connections and writes this connections in the form of equations (mathematical sign model). After he starts a mathematical decision mechanism and, received the numerical values of the unknowns, explains them on the language of the system
