Summary: From what cognitive, Labor Laboratory is seen as a problem whose resolution demands confronting various kinds of tasks involved domains where theoretical and methodological, his approach will be a complex activity. The study takes as a reference the Field Theory Conceptual G. Vergnaud and epistemology of science framed trends in non-standard. It develops a model of the dynamics of learning in the TL in the teaching of physics (MATLaF) believes that the tasks of scientific experimental work as subproblemas the experimental situation, which demanded conceptualizations domain methodological interrelationship with the domain the theoretical situation. Two trials were conducted in a laboratory course with students of physics teacher. A pilot study to assess the feasibility of the model MATLaF and methodology designed to implement teaching and research, and get a first approximation of the invariant Operatorios (IO) of the students under the domain methodology. And a trial aimed at evaluating the effectiveness of the proposal on the conceptual development of the students in connection with the domain teórico-metodológico-epistemológico, in a TL raised the issue of Mechanical Waves. As the TL seems to be more activity that may contribute to the development of a vision about the nature of science, assessed the impact of the test on the conceptions of the participants. To that end, he built a tool to evaluate those conceptions in relation to the pilot who was validated with a sample of college students. The results show that the theoretical domain ceased to activate all aspects of the concepts that do not relate to the ideas of science compared to the problems raised. As for the domain methodology, the majority of students (4 of 5) developed concepts related to them, discriminating between the tasks and recognizing that their implementation requires theorems and concepts relating to the pilot, whose activation is dependent on the situation; and interrelating the theoretical and phenomenological at different stages of the TL. Overall, there was a favorable development in the conceptual development teórico-epistemológico-metodológico of most students, which we consider acceptable from this theoretical work.

Summary: In this research have developed various mathematical techniques that allow thinking and analytical approximate resolution of the problem of the Earth's rotation using the formalism hamiltoniano. In particular, it has obtained the necessary procedure for calculating the forces canonical work through virtual system. Likewise, there have been general expressions of the kinetic energy, potential energy and time for a generalized model terrestrial k-capas, obtaining the shape of the deformation kinematics of the fluid layers. It has been given a geometrical interpretation for a particular type of canonical transformations defined by Andoyer (1923). Since this method has been tested canonicidad of combined Andoyer a layer of Andoyer multi-layered and Andoyer referred to the ecliptic mobile. It has developed a new algorithm which enables the achievement of free frequencies as nutation approximations asintoticas with the desired accuracy. Finally, it has extended the method developed by Getino and Ferrándiz (2001) to obtain forced mutations. These methods have been applied to identify mutations free and forced different models of Earth consist of one, two and three layers. Specifically, Chapter 2 is considered the free movement of rotation of a realistic model of Earth consists of three layers: mantle, outer liquid core and solid core domestic. By formalism hamiltoniano obtained analytical expressions for mutations free to do so by defining a set of variables unique canonical not allowing treatment of simple mathematical problem. These solutions are compared with those obtained by other authors numerically, showing a complete coincidence up to the first order in the elipticiades. In chapter 3, explores the free movement of rotation of Earth is not a model of rigid two layers, considering that both the mantle as the core liquid bodies are triaxial. Also, it assumes the existence of a moment of force disipativo viscoso-electromagnético on the border manto-núcleo not symmetrical. By formalism hamiltonaino variables not unique, are obtained frequencies free nutation of the above model, discussing the effect that the nosimetría takes such frequencies, concluding that such a situation, especially concerning the triaxialidad of layers, influences significantly in the value of the frequency FCN (Free Core Nutation). Chapter 4 examines the contribution to the series dentuación due to triaxialidad a model of Earth not rigid two layers. It applies the canonical formalism to study the terms semidiurnos from coefficients C22 and S22 of geopotential (direct effect), ie not zonal harmonics of degree two. Once calculated for the generating function of the problem forced the analytical expressions are obtained from the flat Andoyer and contained, and the numerical values based on the analytical formulas. Finally, the last chapter calculates a new contribution in the movement of nutation model of a rigid triaxial Land (indirect effect). Thus, within a formalism hamiltoniano express the energy potential of the system in termios of variables acción-ángulo the problem without disrupting. Based on these expressions are derived contributions to the series of nutation model, some of which are above the level of truncation established on the model of an officer rotation Earth rigid REN-2000, but were not considered it .

Summary: The contemporary education as constructivism holds the dominant position in which he supported the conceptualization of the processes of teaching and learning. Focusing on this theoretical framework, we have identified three components that nourish our work, which are the sociocultural perspective Lev Vygotsky, meaningful learning of David Ausubel and approach of the Education for International Understanding relied on the theory of multiple intelligences Howard Gardener. Our proposal takes some basic ideas of these perspectives, as an integral structural axis of constructivist learning and teaching online. The thesis makes a theoretical model is called "Model for Educators Constructivista Sciences Online" (abreviamos as MoCEL), which raised its objectives, outlines six dimensions of analysis necessary for their development (Contextual , technology, pedagógica-didáctica, cognitive, epistemological and communications) and proposes a methodology of work organized into four stages. To begin the design and development of a specific application within MoCEL, it is imperative to conduct the investigation stage diagnosis, in order to characterize the proposal contextual dimension to our model. This is done through three investigations: the first explores the characteristics profile teaching, determined by the theoretical framework of Education for International Understanding (EpC) adopts MoCEL. The second investigation is exposed collects information about the system technology support for teachers who possess, as well as the skills of the users connection to the computer and its programs. Also investigated websites relating to the Urban Solid Waste, as tools for development of this material. It performs a specific proposal on CD-ROM technology on the Urban Solid Waste, which includes a computational simulation for the management of this environmental problem. It implements the evaluative research methodology called CIPP, detailing the methods and the variety of tools used to carry out this investigation. Results are obtained and interpreted taking into account the dimensions of analysis proposed by MoCEL for each phase of the investigation. These results, although they can not be generalized to other developments, provide assessments to help improve this model and facilitate future proposals using MoCEL, in other thematic different from those addressed in this thesis. In addition, an assessment of the computational simulation for the management of solid waste (SiGRES) with the aim of identifying strengths and weaknesses of the development and application possibilities in the classroom.
