One of the most fundamental problems formulated to machine learning is the development of habits and abilities in complex systems modeling. At the present paper a system named Generator of Problems Hypermedia is described and developed. This software system allows automating the process of optimization problem construction and automatic generation of problem statements for complex problem situations using the multimedia technology tools and intelligent interfaces. The work possesses significant importance in the introduction of computers in Education and in the development of Mathematical Modeling. Their successful application increases considerably the efficiency of the teaching and learning process. By means of the rational introduction of the Multimedia Technology tools students have exercised the construction and representation process of is used with the technology .net for Windows, as welloptimization problem situations. The system C as diverse multimedia technologies. [ABSTRACT FROM AUTHOR]

This paper synthesizes the results of an investigation work (Montiel, 2002) about the didactic system's interaction, when these are carried out in an education scenario at distance. We report, within the socioepistemological framework and empirical evidence, how a derivative learn situation can be develop, taking this (the derivative) like variations successive organization.

Abstract: The purpose of this paper is to re-examine the relationships between mathematical problem solving and learning mathematics. After introducing a diagram representing the notion of problem solving, four types of problem solving approaches used in mathematics classrooms will be distinguished according to which aspect of that diagram is attended to. In examining each type of problem solving approach, what is expected to be obtained by students and what can be possible support in that approach will be discussed on the basis of the research literature. Through such examination, it will be shown that a teacher''s choice of problem situations and ways of interventions is critical to enabling students to experience ‘authentic’ problem solving and the choice should reflect the teacher''s intention. In the last part, problem solving as a way to treat mathematical theories will be discussed and the limitation of problem solving approach raised by the issue of mathematical culture will be made explicit.
