SOLAR
The Sun, source of life and origin of other forms of energy that man has used since the dawn of history, can meet all our needs, if we learn how to make a rational light continuously pours on the planet. Has shone in the sky for about five billion years, and is estimated to have not yet reached even half of its existence. This year, the sun casts on the earth four thousand times more energy than we consume.
It should, however, noted that there are some problems that we face and overcome. Apart from the difficulties that would lead to advanced solar energy policy itself must be borne in mind that this power is subject to continuous fluctuations and more or less abrupt. For example, solar radiation is lower in winter, usually just when they most need.
The "solar cells", arranged in solar panels and produce electricity in the first space satellites. Currently emerging as the ultimate solution to the problem of rural electrification, with a clear advantage over other alternatives because, lacking panels moving parts, are totally impervious to the passage of time, do not pollute or cause any noise at all, do not consume fuel and maintenance free. Furthermore, although with less efficiency, also work on cloudy days, since they capture the light filtering through the clouds.
solar energy can be perfectly complemented with other conventional energy to avoid the need for large and expensive storage systems. Thus, a well-insulated house can have solar heating and hot water, with the support of a conventional gas or electrical work only during periods without sun. The cost of "energy bill" would be only a fraction of that achieved without the existence of the solar system.

What Does That R On The Pokemon Cards Mean
"We are taking a major step from the technological point of view and in the exercise of sovereignty", said Minister of Popular Power for Education
Irmo too, that the Simon Bolivar satellite will enhance the benefits of tele-education program that will educate thousands of Venezuelans in the most remote national geography.
Navarro indicated that this tool will impact positively "in the Latin American unit, based on a technology platform of the utmost importance, as is the Simón Bolívar satellite.
From Ground Station
went on to note that the participation of Venezuelan personnel has not only shown along the assembly line, assembly, system test, but also in the construction of this complex, challenging project from technological point of view.

Fridge Thermostat How Work
The computer is a powerful intellectual tool, which is incorporated in education and other means of support for teaching and learning, it allows easy and flexible thinking, expanding the minds of students , actively engaging in their own learning.
The interaction with the computer allows you to change its role as receiver manufacturer, from spectator to active participant. On the other hand, when using a computer as instructional support the learner can be addressed individually, thereby facilitating the humanization of education, thus taking the student a unique learning experience.
Because there is no unique pattern of learning and processing, but on the contrary, the students know, learn, perceive, process, analyze, record, synthesize and evaluate information differently from each other; computer can solve this dilemma as it offers methodologies and diverse teaching methods for learning the same material, considering needs, learning styles and rhythms.
Another important potential of the computer is its ability to amplify the students' experiences, creating microworlds (Papert 1980) , which typically are not available to the learner directly, this means that the student takes small pieces of reality which can be controlled.
However, regarding the evaluation, without doubt, the computer can be fundamental, because it achieves an intimate combination of testing and learning and may even go beyond, the learner can receive immediate reinforcement when the response is correct, not only because it indicates that something is right, but through an auxiliary construction or revision of the problem, thus proving that the focus is on learning and not on the test.
Finally, the use of this tool allows students to control their pace of learning, this means that the content can be dosed and sequenced according to their needs and learning pace, this means to promote students progress and learn according to their own rhythms and not all at the same rate as in the traditional classroom.
is why our mission is and will always be futuristic, forward-looking and responsive to the advances of our time. J. Sánchez (1995)

According Borge Holmberg (2000) , "The term of "distance learning" covers different forms of studies at all levels that are not under the continuous and immediate supervision of tutors present with their students in the classroom, but nevertheless, benefit planning, guides and follow a tutorial organization. " "The most important general characteristics of distance learning is that it relies on direct communication ... it brings consequences that brings about the general characteristics of distance education can be grouped into six (6) categories:
A) The base distance learning course is usually a pre -produced which is usually printed but may also be presented through means other than through the written word, such as audio or video tapes, radio programs, television or experimental games ...
B) The round-trip organized communication takes place between students and a support organization.
C) Distance education takes into account the individual study ...
D) Given the current produced is easily utilized by a large number of students and with minimal expense, distance education can be a form of mass communication .
E) When preparing a program of mass communication is practical to apply the methods of individual work. These methods include; planning, nationalization procedures, such as division of labor, mechanization, automation, control and verification.
F) involved technological approaches do not prevent personal communication in the form of dialogue is central to the study at a distance. This occurs even when there is communication computed. It believes that distance learning is organized as a mediated form of guided didactic conversation. "
In this sense, the researchers detected several problems in teaching our students and curricula that result from an expires each year after year due to the rapid development of technology, which leaves no room for error. It is then an urgent search for solutions with a more dynamic model that can reach more remote schools one of the most appropriate way distance education is the use of defamation and technology (ICT).
Virtual Education.
In today's world of ICT development that forced a shift in the educational system which demonstrates the need for continuous learning or along to acquire life skills cognitive before rapid technological change. A new paradigm is taking us the information society to knowledge society, I have imposed on the education paradigm of technological convergence.
For a virtual system can be considered elements of technological convergence, ie, to achieve the anointing between broadcasting, information technology and telecommunications.
virtual education is fully identified with distance education, the latter may or may not be delivered virtually, but education is delivered to remote virtual by definition. Currently offer distance learning programs throughout the world, employing only the computer as a medium and are rarely linked to the radio and TV education.
Also discuss the role of student to a range of qualities with cognitive independence, while seeking information through modern techniques responsibility, because it assumes itself the knowledge and preparation, developing a human value, creativity, since promote ICT finding inventive new ways to solve professional problems, expressiveness, due to the need for communication of guidance encourages expressive capacity, research capacity, since engender ICT the spirit of inquiry.
The development of materials and demand acquires another connotation. The involvement of multi groups, trans and around interdisciplinary teaching resources is a necessity for realizing the full potential that the model provides.
evaluation criteria and approaches
All these programs have new elements, educational models that retrieve certain theoretical premises of pedagogy and communication: constructivism and dialogic communication and horizontal this now had been limited. But in our view can not completely lost the influence of the relationship. Through distance learning, virtual education develops values \u200b\u200btransforms reality into the subject of learned and cognitive independence rises. is of great importance to academic and professional mediate the use of ICT across the education subsystem.

Technologies Information and Communication Technologies are transforming our personal and professional lives. The ways in which we have access to communication and learning are being transformed and the media and how we relate to others. The growing impact of technology in educational institutions requires a radical transformation not only of organizational structures but also in the management of learning, attitudes and values. However, since the introduction of teaching machines in the seventies, it has been emphasized in the use of these tools in the design education more relevant. These have been used without having sought answers to the "why" and "for what." We analyze the implications of use in countries like ours with dependent economies, which have been strongly affected by the consequences of globalization of the market based on new technology. The colleges at all levels must be restructured to integrate the use of and redefine the forms and objectives of education by answering questions such as:
1) How the Information and Communication Technologies affect the curriculum, school organization and means of evaluation?
2) How do we change the role of teachers taking into account the use of new technologies'?
information and to achieve efficient, integrated approach is needed to guide educational policies, institutional arrangements, material resources and stakeholders. It is not doing the same thing differently, but to change the current objectives in accordance with the requirements of the new technology used to articulate the process education.
What contributions would give us as teachers to enrich tic using the current educational curriculum in our country?

A key issue in the first unit of the course is the "Systems" and when he speaks of them have given a whole whose properties are not attributable to simple addition of the properties of their parts or components. You can find many definitions: "System is an organized and complex," "a set or combination of things or parts forming a complex or unitary whole. "is a set of objects united by some form of interaction and interdependence." The border line between the system and its environment allowed certain arbitrariness. "According to Bertalanffy, a system is" a reciprocally related set of units. "As we see, in the usual definitions identify systems as sets of elements that are closely related to each other, which maintain the system directly or indirectly linked more or less stable overall performance of which pursues usually some type of target. Based on these definitions, we can begin interventions at the forum, which should provide information to concerning: 1.-What are the elements and most important characteristics of the systems? 2.-Classification of systems in relation to the environment and its origin. 3.-Identify and list examples of systems in your environment.
