What is Technology?

Assessment (analysis and normative evaluation) of a particular technical device, system, or procedure with regard to a defined set of criteria, goals or objectives (e.g. technical security assessment according to the standards of the Orange Book).

The belief that technology develops (see development) by its own laws, that it realizes its own potential, limited only by the material resources available, and must therefore be regarded as an autonomous (see autonomy) system controlling and ultimately permeating all other subsystems of society. Evidence for the first proposition is largely taken from the natural history of technology, its progressive character and the cooccurance of independent (see independence) inventions. Evidence for the second proposition stems from the unwarranted generalization that everything that is invented is ultimately installed and ignores human playfulness, individual and collective interests and man's cognitive limitations. The conclusion is nevertheless supported by the fact that technology has indeed penetrated all spheres of human existence from interpersonal communication, to definitions of the quality of life in technological terms. (Krippendorff)
An object or sequence of operations created by man to assist in achieving some goal. A technology is a body of human knowledge that can be passed along from one place to another and from one generation to the next. Examples of technologies are: a bow and arrow; a birth control pill; a nuclear reactor; a legislature; and a planning, programming, budgeting system of accounting.
The body of knowledge about, and the systematic study of, methods, techniques and hardware applied in the
adaptation of the physical environment to man's needs and wants. The application of scientific knowledge to build or improve the infrastructure of agriculture, industry government and daily life. (Technology must not be confused with the very infrastructure it generates). Technology has autocatalytic properties. It favors the use of technical devices and processes even in solving social problems, e.g., by using fertilizers to enhance agricultural production rather than a different form of work organization, by using computers for national planning rather than decentralized decision making processes. (Krippendorff)
The systematic knowledge and the methods and procedures which can be used in a specific area in order to resolve practical problems. In some languages, e.g. French, Spanish, and German, this is clearly distinguished from
technic" ("technique", "tecnica", "Technik") which is the practical skill to use knowledge, methods, and procedures in a particular case in order to resolve a specific practical problem.
Technology Assessment (TA) is the encompassing analysis and evaluation of technologies in order to develop alternatives for decision-making (6). ta has three components. In a first step possible consequences of the use of a technology have to be investigated whereby a particular interest is given to unexpected and long-term consequences. In a second step the technology itself and its immediate strengths and weaknesses have to be evaluated as well as its unexpected and long-term consequences. In a third step variants and alternatives have to be elaborated. This definition of Technology Assessment corresponds to the proposal of the VDI (Association of German Engineers) in its "Guidelines to Technology Assessment" (7). (Hornung
The analysis of the implementation of a technology and its evaluation with regard to immediate and more general objectives. Technology Assessment comprises two parts. The first is an analytical, factual, part of scientific analysis of the functioning and of the effects of the technology considered. This takes into consideration in particular potential long-term and unexpected side effects. The second part is the normative evaluation of the results of the analysis with regard to < href ="CRITERION.HTML">criteria, goals, and objectives. This includes the comparison to other alternatives (other technologies or non-implementation).

The use of computer-based information processing in telecommunication and the use of telecommunication to allow computers to transfer programmes and data to each other (WHO: Telematics p. 100)the philosophical study of manifestations of design or purposes in natural processes or occurrences, under the belief that natural processes are not determined by mechanism but rather by their utility in an overall natural design. Dysteleology is the doctrine of purposelessness in nature. (American Heritage Dictionary) Teleology is associated with vitalism. It explains apparently purposeful animal behavior by saying that the action is performed because it will later be advantageous to the animal. Science, on the other hand, has sought to explain apparently purposeful behavior through the theory of mechanism. The notion that an organism contains a model of the actual world and a model of the desired world and acts so as to make the actual world conform to the desired world is compatible with the theory of mechanism.the element of apparent purpose or possession of a project in the organization of living systems, without implying any vitalistic connotations. Frequently considered as a necessary if not sufficient defining feature of the living organization. (Maturana and Varela, 1979) "With the addition of a correction channel equal to or exceeding in capacity the amount of noise in the original channel, it is possible to so encode (see encoding) the correction data sent over this channel that all but an arbitrarily small fraction of the errors contributing to the noise are corrected. This is not possible if the capacity of the correction channel is less than the noise" (see redundancy). This theorem is an isomorph of the law of requisite variety. (Krippendorff)Literally, the original written or printed form of a literary work considered as the authoritative source of interpretations. In cybernetics, data with an inherent pattern, structure or organization through which the meanings are revealed (see context). (Krippendorff)
An imaginative formulation of apparent relationships or underlying principles of certain observed phenomena. It may have been verified to some extent, or it may be pure hypothesis or conjecture. (Iberall)
A theory proposed by B. Russell that rules out self-reference in order to prevent the emergence of antinomies and paradoxes in logic. It states that a class is of a logical type higher (see ordinality) than its members and, because logical types must not be confused, no class can contain itself as a member. E.g., the law of the excluded middle which states that propositions can be either true or false is a proposition and should therefore be either true or false. But because it can only be true (else it would not be a law), it defies its own claim. Russell's solution is that the law is a proposition about propositions and must not be confused with the propositions to which it refers (see meta-). According to the theory, self-referential statements are neither true nor false but meaningless. The theory has been influential in linguistics by recognizing the importance of logical as well as grammatical restrictions on the combinations of words (see language). It provided support on attacks on logical positivism, especially on its verification principle and has inspired inquiries into communication pathologies that arise from the confusion among logical types, e.g., of content and relationship aspects of communications (see double bind). However, by exorcising self-reference, the theory of logical types bas retarded the development of theory, largely cognitive theory, in areas where self-reference is prevalent. With its focus on circularity cybernetics has transcended the theory and essentially solved the problem's self-reference originally posed. (Krippendorff)
The quantity of energy no longer available to do physical work. Every real process converts energy into both work or a condensed form of energy and waste. Some waste may be utilized in processes other than those generating it (see recycling) but the ultimate waste which can no longer support any process is energy in the form of dispersed heat (see second law of thermodynamics). All physical process, despite any local and temporal concentration of energy they may achieve, contribute to the increased overall dispersion of heat. Entropy therefore irreversibly increases in the known universe. (Krip
pendorff
)

That branch of physics which is concerned with the storage, transformation and dissipation of energy (including the flow of heat from which the term is derived). Its first law, or the conservation law, states that energy can neither be created nor destroyed. This law provides the basis for all quantitative accounts of energy, regardless of its form, and makes energy the most important concept in physics. Its second law, or the entropy law, states that in all processes some of the energy involved irreversibly looses its ability to do work and is degraded in quality. The latter is called thermodynamic entropy whose extreme form is dispersed heat and manifested in a uniform temperature distribution. Another statement of this second law is that in any process entropy never decreases. The irreversibility of physical processes implicit in this law makes the entropy law probably the most important law in understanding terrestrial processes including living organisms and social forms. The third law of thermodynamics, or the asymptotic law, states that all processes slow down as they operate closer to the thermodynamic equilibrium making it difficult to reach that equilibrium in practice. This law suggests that the powerful and fast changes which are typical of technology and characteristic of living forms of organization are bound to occur only at levels far removed from thermodynamic equilibrium. (Krippendorff)
The law of asymptotic decelleration (see thermodynamics) . (Krippendorff)

Technology and society

Technology and pet society or technology and culture refers to the cyclical co-dependence, co-influence, co-production of technology and society upon the other (technology upon culture, and vice-versa). This synergistic relationship occurred from the dawn of humankind, with the invention of the simple tools; and continues into modern technologies such as the printing press and computers.

Modern examples

There are an extraordinary number of examples how science and technology has helped us that can be seen in society today. One great example is the mobile phone. Ever since the invention of the telephone society was in need of a more portable device that they could use to talk to people. This high demand for a new product led to the invention of the mobile phone, which did, and still does, greatly influence society and the way people live their lives. Now many people are accessible to talk to whoever they want no matter where any of the two people are. All these little changes in mobile phones, like Internet access, are further examples of the cycle of co-production. Society's need for being able to call on people and be available everywhere resulted in the research and development of mobile phones. They in turn influenced the way we live our lives. As the populace relies more and more on mobile phones, additional features were requested. This is also true with today's modern media player.
Society also determined the changes that were made to the previous generation media player that the manufactures developed. Take for example, today's media players. At the beginning, cassettes were being used to store data. However, that method was large and cumbersome so the manufactures developed compact disks, which were smaller and could hold more data. Later, compact disks were again too large and did not hold enough data that forced today's manufactures to create MP3 players which are small and holds large amount of data. Today's society determined the course of events that many manufactures took to improving their products so today's consumers will purchase their products.

Economics and technological development


Looking back into ancient history, economics can be said to have arrived on the scene when the occasional, spontaneous exchange of goods and services began to occur on a less occasional, less spontaneous basis. It probably did not take long for the maker of arrowheads to realize that he could probably do a lot better by concentrating on the making of arrowheads and barter for his other needs. Clearly, regardless of the goods and services bartered, some amount of technology was involved—if no more than in the making of shell and bead jewelry. Even the shaman's potions and sacred objects can be said to have involved some technology. So, from the very beginnings, technology can be said to have spurred the development of more elaborate economies.
In the modern world, superior technologies, resources, geography, and history give rise to robust economies; and in a well-functioning, robust economy, economic excess naturally flows into greater use of technology. Moreover, because technology is such an inseparable part of human society, especially in its economic aspects, funding sources for (new) technological endeavors are virtually illimitable. However, while in the beginning, technological investment involved little more than the time, efforts, and skills of one or a few men, today, such investment may involve the collective labor and skills of many millions.
[edit] Funding
Consequently, the sources of funding for large technological efforts have dramatically narrowed, since few have ready access to the collective labor of a whole society, or even a large part. It is conventional to divide up funding sources into governmental (involving whole, or nearly whole, social enterprises) and private (involving more limited, but generally more sharply focused) business or individual enterprises.
[edit] Government funding for new technology
The government is a major contributor to the development of new technology in many ways. In the United States alone, many government agencies specifically invest billions of dollars in new technology.
[In 1980, the UK government invested just over 6-million pounds in a four-year program, later extended to six years, called the Microelectronics Education Programme (MEP), which was intended to give every school in Britain at least one computer, software, training materials, and extensive teacher training. Similar programs have been instituted by governments around the world.]
Technology has frequently been driven by the military, with many modern applications being developed for the military before being adapted for civilian use. However, this has always been a two-way flow, with industry often taking the lead in developing and adopting a technology which is only later adopted by the military.
Entire government agencies are specifically dedicated to research, such as America's National Science Foundation, the United Kingdom's scientific research institutes, America's Small Business Innovative Research effort. Many other government agencies dedicate a major portion of their budget to research and development.
[edit] Private funding
Research and development is one of the biggest areas of investments made by corporations toward new and innovative technology.
foundations and other nonprofit organizations contribute to the development of technology. In the OECD, about two-thirds of research and development in scientific and technical fields is carried out by industry, and 20 percent and 10 percent respectively by universities and government. But in poorer countries such as Portugal and Mexico the industry contribution is significantly less. The U.S. government spends more than other countries on military research and development, although the proportion has fallen from about 30 percent in the 1980s to less than 10 percent.[1]
[edit] Other economic considerations
Appropriate technology, sometimes called "intermediate" technology, more of an economics concern, refers to compromises between central and expensive technologies of developed nations and those which developing nations find most effective to deploy given an excess of labour and scarcity of cash.
Persuasion technology: In economics, definitions or assumptions of progress or growth are often related to one or more assumptions about technology's economic influence. Challenging prevailing assumptions about technology and its usefulness has led to alternative ideas like uneconomic growth or measuring well-being. These, and economics itself, can often be described as technologies, specifically, as persuasion technology.

Sociological factors and effects




The use of technology has a great many effects; these may be separated into intended effects and unintended effects. Unintended effects are usually also unanticipated, and often unknown before the arrival of a new technology. Nevertheless, they are often as important as the intended effect.
[edit] Values
The implementation of technology influences the values of a society by changing expectations and realities. The implementation of technology is also influenced by values. There are (at least) three major, interrelated values that inform, and are informed by, technological innovations:
Mechanistic world view: Viewing the universe as a collection of parts, (like a machine), that can be individually analyzed and understood (McGinn 1991). This is a form of reductionism that is rare nowadays. However, the "neo-mechanistic world view" holds that nothing in the universe cannot be understood by the human intellect. Also, while all things are greater than the sum of their parts (e.g., even if we consider nothing more than the information involved in their combination), in principle, even this excess must eventually be understood by human intelligence. That is, no divine or vital principle or essence is involved.
Efficiency: A value, originally applied only to machines, but now applied to all aspects of society, so that each element is expected to attain a higher and higher percentage of its maximal possible performance, output, or ability. (McGinn 1991)
Social progress: The belief that there is such a thing as social progress, and that, in the main, it is beneficent. Before the Industrial Revolution, and the subsequent explosion of technology, almost all societies believed in a cyclical theory of social movement and, indeed, of all history and the universe. This was, obviously, based on the cyclicity of the seasons, and an agricultural economy's and society's strong ties to that cyclicity. Since much of the world is closer to their agricultural roots, they are still much more amenable to cyclicity than progress in history. This may be seen, for example, in Prabhat rainjan sarkar's modern social cycles theory. For a more westernized version of social cyclicity, see Generations: The History of America's Future, 1584 to 2069 (Paperback) by Neil Howe and William Strauss; Harper Perennial; Reprint edition (September 30, 1992); ISBN 0-688-11912-3, and subsequent books by these authors.
[edit] Ethics
Winston (2003) provides an excellent summary of the ethical implications of technological development and deployment. He states there are four major ethical implications:
Challenges traditional ethical norms. Because technology impacts relationships among individuals, it challenges how individuals deal with each other, even in ethical ways. One example of this is challenging the definition of "human life" as embodied by debates in the areas of abortion, euthanasia, capital punishment, etc., which all involve modern technological developments.
Creates an aggregation of effects. One of the greatest problems with technology is that its detrimental effects are often small, but cumulative. Such is the case with the pollution from the burning of fossil fuels in automobiles. Each individual automobile creates a very small, almost negligible, amount of pollution, however the cumulative effect could possibly contribute to the global warming effect. Other examples include accumulations of chemical pollutants in the human body, urbanization effects on the environment, etc.

Changes the distribution of justice. In essence, those with technology tend to have higher access to justice systems. Or, justice is not distributed equally to those with technology versus those without.
Provides great power. Not only does technology amplify the ability, and hence the strength, of humans, it also provides a great strategic advantage to the human(s) who hold the greatest amount of technology. Consider the strategic advantage gained by having greater technological innovations in the military, pharmaceuticals, computers, etc. For example, Bill Gates has considerable influence (even outside of the computer industry) in the course of human affairs due to his successful implementation of computer technology.
[edit] Lifestyle
In many ways, technology simplifies life.
The rise of a leisure class
A more informed society,which can make quicker responses to events and trends
Sets the stage for more complex learning tasks
Increases multi-tasking (although this may not be simplifying)
Global networking
Creates denser social circles
Cheaper prices
Greater specialization in jobs
In other ways, technology complicates life.
Pollution is a serious problem in a technologically advanced society (from acid rain to Chernobyl and Bhopal)
The increase in transportation technology has brought congestion in some areas
Technicism (although this may not be complicating)
New forms of danger existing as a consequence of new forms of technology, such as the first generation of nuclear reactors
New forms of entertainment, such as video games and internet access could have possible social effects on areas such as academic performance
Increased probability of some diseases and disorders, such as obesity
Social separation of singular human interaction. Technology has increased the need to talk to more people faster.
Structural unemployment
Anthropocentric climate change
[edit] Institutions and groups
Technology often enables organizational and bureaucratic group structures that otherwise and heretofore were simply not possible. Examples of this might include:
The rise of very large organizations: e.g., governments, the military, health and social welfare institutions, supranational corporations.
The commercialization of leisure: sports events, products, etc. (McGinn)
The almost instantaneous dispersal of information (especially news) and entertainment around the world.
[edit] International
Technology enables greater knowledge of international issues, values, and cultures. Due mostly to mass transportation and mass media, the world seems to be a much smaller place, due to the following, among others:
Globalization of ideas
Embeddedness of values
Population growth and control
Others

Environment

Technology provides an understanding, and an appreciation for the world around us.
Most modern technological processes produce unwanted byproducts in addition to the desired products, which is known as industrial waste and pollution. While most material waste is re-used in the industrial process, many forms are released into the environment, with negative environmental side effects, such as pollution and lack of sustainability. Different social and political systems establish different balances between the value they place on additional goods versus the disvalues of waste products and pollution. Some technologies are designed specifically with the environment in mind, but most are designed first for economic or ergonomic effects. Historically, the value of a clean environment and more efficient productive processes has been the result of an increase in the wealth of society, because once people are able to provide for their basic needs, they are able to focus on less-tangible goods such as clean air and water.
The effects of technology on the environment are both obvious and subtle. The more obvious effects include the depletion of nonrenewable natural resources (such as petroleum, coal, ores), and the added pollution of air, water, and land. The more subtle effects include debates over long-term effects (e.g., global warming, deforestation, natural habitat destruction, coastal wetland loss.)
Each wave of technology creates a set of waste previously unknown by humans: toxic waste, radioactive waste, electronic waste.
One of the main problems is the lack of an effective way to remove these pollutants on a large scale expediently. In nature, organisms "recycle" the wastes of other organisms, for example, plants produce oxygen as a by-product of photosynthesis, oxygen-breathing organisms use oxygen to metabolize food, producing carbon dioxide as a by-product, which plants use in a process to make sugar, with oxygen as a waste in the first place. No such mechanism exists for the removal of technological wastes.
Humanity at the moment may be compared to a colony of bacteria in a Petri dish with a constant food supply: with no way to remove the wastes of their metabolism, the bacteria eventually poison themselves.

Construction and shaping


Choice
Society also controls technology through the choices it makes. These choices not only include consumer demands; they also include:
the channels of distribution, how do products go from raw materials to consumption to disposal;
the cultural beliefs regarding style, freedom of choice, consumerism, materialism, etc.;
the economic values we place on the environment, individual wealth, government control, capitalism, etc.
According to Williams and Edge (1996), the construction and shaping of technology includes the concept of choice (and not necessarily conscious choice). Choice is inherent in both the design of individual artifacts and systems, and in the making of those artifacts and systems.
The idea here is that a single technology may not emerge from the unfolding of a predetermined logic or a single determinant, technology could be a garden of forking paths, with different paths potentially leading to different technological outcomes. This is a position that has been developed in detail by Judy Wajcman Therefore, choices could have differing implications for society and for particular social groups.hh
[edit] Autonomous technology
In one line of thought, technology develops autonomously, in other words, technology seems to feed on itself, moving forward with a force irresistible by humans. To these individuals, technology is "inherently dynamic and self-augmenting." (McGinn 1991, p. 73) Jacques Ellul is one proponent of the irresistibleness of technology to humans. He espouses the idea that humanity cannot resist the temptation of expanding our knowledge and our technological abilities. However, he does not believe that this seeming autonomy of technology is inherent. But the perceived autonomy is due to the fact that humans do not adequately consider the responsibility that is inherent in technological processes.
Another proponent of these ideas is Langdon Winner who believes that technological evolution is essentially beyond the control of individuals or society.
[edit] Government
Individuals rely on governmental assistance to control the side effects and negative consequences of technology.
Supposed independence of government. An assumption commonly made about the government is that their governance role is neutral or independent. However some argue that governing is a political process, so government will be influenced by political winds of influence. In addition, because government provides much of the funding for technological research and development, it has a vested interest in certain outcomes. Other point out that the world's biggest ecological disasters, such as the Aral Sea, Chernobyl, and Lake Karachay have been caused by government projects, which are not accountable to consumers.
Liability. One means for controlling technology is to place responsibility for the harm with the agent causing the harm. Government can allow more or less legal liability to fall to the organizations or individuals responsible for damages.
Legislation. A source of controversy is the role of industry versus that of government in maintaining a clean environment. While it is generally agreed that industry needs to be held responsible when pollution harms other people, there is disagreement over whether this should be prevented by legislation or civil courts, and whether ecological systems as such should be protected from harm by governments.
Recently the social shaping of technology has had new influence in the fields of e-science and e-social science in the United Kingdom, which has made centers focusing on the social shaping of science and technology a central part of their funding programs.

Educational technology


Educational technology (also called learning technology) is the study and ethical practice of facilitating learning and improving performance by creating, using and managing appropriate technological processes and resources."[1] The term educational technology is often associated with, and encompasses, instructional theory and learning theory. While instructional technology covers the processes and systems of learning and instruction, educational technology includes other systems used in the process of developing human capability. Educational Technology includes, but is not limited to, software, hardware, as well as Internet applications and activities.

Perspectives and meaning


Educational technology is most simply and comfortably defined as an array of tools that might prove helpful in advancing student learning. Educational Technology relies on a broad definition of the word "technology". Technology can refer to material objects of use to humanity, such as machines or hardware, but it can also encompass broader themes, including systems, methods of organization, and techniques. Some modern tools include but are not limited to overhead projectors, laptop computers, and calculators. Newer tools such as "smartphones" and games (both online and offline) are beginning to draw serious attention for their learning potential.
Those who employ educational technologies to explore ideas and communicate meaning are learners or teachers.
Consider the Handbook of Human Performance Technology.[2] The word technology for the sister fields of Educational and Human Performance Technology means "applied science." In other words, any valid and reliable process or procedure that is derived from basic research using the "scientific method" is considered a "technology." Educational or Human Performance Technology may be based purely on algorithmic or heuristic processes, but neither necessarily implies physical technology. The word technology, comes from the Greek "Techne" which means craft or art. Another word "technique", with the same origin, also may be used when considering the field Educational technology. So Educational technology may be extended to include the techniques of the educator.[citation needed]
A classic example of an Educational Psychology text is Bloom's 1956 book, Taxonomy of Educational Objectives.[3] Bloom's taxonomy is helpful when designing learning activities to keep in mind what is expected of--and what are the learning goals for-- learners. However, Bloom's work does not explicitly deal with educational technology per se and is more concerned with pedagogical strategies.
According to some, an Educational Technologist is someone who transforms basic educational and psychological research into an evidence-based applied science (or a technology) of learning or instruction. Educational Technologists typically have a graduate degree (Master's, Doctorate, Ph.D., or D.Phil.) in a field related to educational psychology, educational media, experimental psychology, cognitive psychology or, more purely, in the fields of Educational, Instructional or Human Performance Technology or Instructional (Systems) Design. But few of those listed below as theorists would ever use the term "educational technologist" as a term to describe themselves, preferring terms like "educator".[citation needed] The transformation of educational technology from a cottage industry to a profession is discussed by Shurville, Browne, and Whitaker.[4]

History

One comprehensive history of the field is Saettler's The evolution of American educational technology.[5] Another worthy title is Larry Cuban'sOversold and Underused - Computers in the Classroom.[6]
For several decades, vendors of equipment such as laptop computers and interactive white boards have been claiming that their technologies would transform classrooms and learning in many positive ways, but there has been little evidence provided to substantiate these claims.[citation needed]
To some extent, the history of educational technology has been marked by a succession of innovations that arrive with much fanfare but often fade into the background once fully tested, as Cuban argues in the above title.[citation needed]
[edit] Theories and practices
Three main theoretical schools or philosophical frameworks have been present in the educational technology literature. These are Behaviorism, Cognitivism and Constructivism. Each of these schools of thought are still present in today's literature but have evolved as the Psychology literature has evolved.
[edit] Behaviorism
This theoretical framework was developed in the early 20th century with the animal learning experiments of Ivan Pavlov, Edward Thorndike, Edward C. Tolman, Clark L. Hull, B.F. Skinner and many others. Many psychologists used these theories to describe and experiment with human learning. While still very useful this philosophy of learning has lost favor with many educators.
[edit] Skinner's Contributions
B.F. Skinner wrote extensively on improvements of teaching based on his functional analysis of Verbal Behavior,[7] and wrote "The Technology of Teaching",[8] an attempt to dispel the myths underlying contemporary education, as well as promote his system he called programmed instruction. Ogden Lindsley also developed the Celeration learning system similarly based on behavior analysis but quite different from Keller's and Skinner's models.
[edit] Cognitivism
Cognitive science has changed how educators view learning. Since the very early beginning of the Cognitive Revolution of the 1960s and 1970s, learning theory has undergone a great deal of change. Much of the empirical framework of Behaviorism was retained even though a new paradigm had begun. Cognitive theories look beyond behavior to explain brain-based learning. Cognitivists consider how human memory works to promote learning.
After memory theories like the Atkinson-Shiffrin memory model and Baddeley's Working memory model were established as a theoretical framework in Cognitive Psychology, new cognitive frameworks of learning began to emerge during the 1970s, 80s, and 90s. It is important to note that Computer Science and Information Technology have had a major influence on Cognitive Science theory. The Cognitive concepts of working memory (formerly known as short term memory) and long term memory have been facilitated by research and technology from the field of Computer Science. Another major influence on the field of Cognitive Science is Noam Chomsky. Today researchers are concentrating on topics like Cognitive load and Information Processing Theory.
[edit] Constructivism
Constructivism is a learning theory or educational philosophy that many educators began to consider in the 1990s. One of the primary tenets of this philosophy is that learners construct their own meaning from new information, as they interact with reality or others with different perspectives.
Constructivist learning environments require students to utilize their prior knowledge and experiences to formulate new, related, and/or adaptive concepts in learning. Under this framework the role of the teacher becomes that of a facilitator, providing guidance so that learners can construct their own knowledge. Constructivist educators must make sure that the prior learning experiences are appropriate and related to the concepts being taught. Jonassen (1997) suggests "well-structured" learning environments are useful for novice learners and that "ill-structured" environments are only useful for more advanced learners. Educators utilizing technology when teaching with a constructivist perspective should choose technologies that reinforce prior learning perhaps in a problem-solving environment.
[edit] Connectivism
Connectivism is "a learning theory for the digital age," and has been developed by George Siemens and Stephen Downes based on their analysis of the limitations of behaviourism, cognitivism and constructivism to explain the effect technology has had on how we live, how we communicate, and how we learn. Donald G. Perrin, Executive Editor of the International Journal of Instructional Technology and Distance Learning says the theory "combines relevant elements of many learning theories, social structures, and technology to create a powerful theoretical construct for learning in the digital age."

Instructional technique and technologies


Problem Based Learning and Inquiry-based learning are active learning educational technologies used to facilitate learning. Technology which includes physical and process applied science can be incorporated into project, problem, inquiry-based learning as they all have a similar educational philosophy. All three are student centered, ideally involving real-world scenarios in which students are actively engaged in critical thinking activities. The process that students are encouraged to employ (as long as it is based on empirical research) is considered to be a technology. Classic examples of technologies used by teachers and Educational Technologists include Bloom's Taxonomy and Instructional Design.

Theorists


This is an area where new thinkers are coming to the forefront everyday. Many of the ideas spread from theorists, researchers, and experts through their blogs. Extensive lists of educational bloggers by area of interest are available at Steve Hargadon's "SupportBloggers" site or at the "movingforward" wiki started by Scott McLeod.[9] Many of these blogs are recognized by their peers each year through the edublogger awards.[10] Web 2.0 technologies have led to a huge increase in the amount of information available on this topic and the number of educators formally and informally discussing it. Most listed below have been around for more than a decade, however, and few new thinkers mentioned above are listed here.

Benefits


Educational technology is intended to improve education over what it would be without technology. Some of the claimed benefits are listed below:
Easy-to-access course materials. Instructors can post the course material or important information on a course website, which means students can study at a time and location they prefer and can obtain the study material very quickly[22]
Student motivation. Computer-based instruction can give instant feedback to students and explain correct answers. Moreover, computer is patient and non-judgmental, which can give the student motivation to continue learning. According to James Kulik, who studies effectiveness of computers used for instruction, students usually learn more in less time when receiving computer-based instruction and they like classes more and develop more positive attitudes toward computers in computer-based classes[23]
Wide participation. Learning material can be used for long distance learning and are accessible to a wider audience[24]
Improved student writing. It is convenient for students to edit their written work on word processors, which can, in turn, improve the quality of their writing. According to some studies, the students are better at critiquing and editing written work that is exchanged over a computer network with students they know[22]
Subjects made easier to learn. Many different types of educational software are designed and developed to help children or teenagers to learn specific subjects. Examples include pre-school software, computer simulators, and graphics software[23]
A structure that is more amenable to measurement and improvement of outcomes. With proper structuring it can become easier to monitor and maintain student work while also quickly gauging modifications to the instruction necessary to enhance student learning.

Criticism


Similar to learning a new task or trade, there is special training that is involved with adding elements of educational technology to the classroom. Without proper training, teachers and students cannot benefit from devices that will improve the quality of education. Pedagogical modifications require an integrative approach to enhance prior practices and not merely replace previous modalities. Devices are a waste of time and money if teachers are not receiving proper training. [26] Another disadvantage is that if teachers plan on using educational technology, they must come to the classroom prior to start time and set everything up and make sure it is all working. Even with the prior prep work, things may have glitches during the class period and it is critical for the teachers to prepare backups and alternate activities should the technology fail to function properly.

Technology in the Classroom


There are many kinds of computer and non-computer technologies currently in use in traditional classrooms. Among these are:
Computer in the Classroom: Having a computer in the classroom is an asset to any teacher. With a computer in the classroom, teachers are able to demonstrate a new lesson, present new material, illustrate how to use new programs, and show new websites. [28]
Class Website: What better way to display your student's work, than to create a web page designed just for your class. Once a web page is designed, teachers can post homework assignments, student work, famous quotes, trivia games, and so much more. In current day society, children know how to use the computer and navigate their way through a website, so why not give them one where they can be a published author. Just be careful as most districts maintain strong policies to manage official websites for a school or classroom.
Class Blogs and Wikis: These are some of a variety of Web 2.0 tools that are currently being implemented in the classroom. Blogs allow for students to maintain a running dialogue, like a journal, of thoughts, ideas, and assignments that also provide for student comment and reiterative reflection. Wikis are more group focused to allow multiple members of the group to edit a single document and create a truly collaborative and carefully edited finished product.
Wireless Classroom Microphones: Noisy classrooms are a daily occurrence, and with the help of microphones, students are able to hear their teachers clearer. Children learn better when they hear the teacher clearly. The benefit for teachers is that they no longer lose their voices at the end of the day.
Mobile devices: Mobile devices such as clickers or smartphone can be used to enhance the experience in the classroom by providing the possibility for professors to get feedback. (read more in the article MLearning).
There are many other tools being utilized depending on the local school board and fund availability. These may include: digital cameras, video cameras, interactive whiteboard tools, document cameras, or LCD projectors.

Technology


Technology is a broad concept that deals with human as well as other animal species' usage and knowledge of tools and crafts, and how it affects a species' ability to control and adapt to its environment. Technology is a term with origins in the Greek technología (τεχνολογία) — téchnē (τέχνη), 'craft' and -logía (-λογία), the study of something, or the branch of knowledge of a discipline.[1] However, a strict definition is elusive; "technology" can refer to material objects of use to humanity, such as machines, hardware or utensils, but can also encompass broader themes, including systems, methods of organization, and techniques. The term can either be applied generally or to specific areas: examples include "construction technology", "medical technology", or "state-of-the-art technology".
The human species' use of technology began with the conversion of natural resources into simple tools. The prehistorical discovery of the ability to control fire increased the available sources of food and the invention of the wheel helped humans in travelling in and controlling their environment. Recent technological developments, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale. However, not all technology has been used for peaceful purposes; the development of weapons of ever-increasing destructive power has progressed throughout history, from clubs to nuclear weapons.
Technology has affected society and its surroundings in a number of ways. In many societies, technology has helped develop more advanced economies (including today's global economy) and has allowed the rise of a leisure class. Many technological processes produce unwanted by-products, known as pollution, and deplete natural resources, to the detriment of the Earth and its environment. Various implementations of technology influence the values of a society and new technology often raises new ethical questions. Examples include the rise of the notion of efficiency in terms of human productivity, a term originally applied only to machines, and the challenge of traditional norms.
Philosophical debates have arisen over the present and future use of technology in society, with disagreements over whether technology improves the human condition or worsens it. Neo-Luddism, anarcho-primitivism, and similar movements criticise the pervasiveness of technology in the modern world, opining that it harms the environment and alienates people; proponents of ideologies such as transhumanism and techno-progressivism view continued technological progress as beneficial to society and the human condition. Indeed, until recently, it was believed that the development of technology was restricted only to human beings, but recent scientific studies indicate that other primates and certain dolphin communities have developed simple tools and learned to pass their knowledge to other generations.

Definition and usage


The Merriam-Webster dictionary offers a definition of the term: "the practical application of knowledge especially in a particular area" and "a capability given by the practical application of knowledge".[1] Ursula Franklin, in her 1989 "Real World of Technology" lecture, gave another definition of the concept; it is "practice, the way we do things around here".[2] The term is often used to imply a specific field of technology, or to refer to high technology or just consumer electronics, rather than technology as a whole.[3] Bernard Stiegler, in Technics and Time, 1, defines technology in two ways: as "the pursuit of life by means other than life", and as "organized inorganic matter."[4]
Technology can be most broadly defined as the entities, both material and immaterial, created by the application of mental and physical effort in order to achieve some value. In this usage, technology refers to tools and machines that may be used to solve real-world problems. It is a far-reaching term that may include simple tools, such as a crowbar or wooden spoon, or more complex machines, such as a space station or particle accelerator. Tools and machines need not be material; virtual technology, such as computer software and business methods, fall under this definition of technology.[5]
The word "technology" can also be used to refer to a collection of techniques. In this context, it is the current state of humanity's knowledge of how to combine resources to produce desired products, to solve problems, fulfill needs, or satisfy wants; it includes technical methods, skills, processes, techniques, tools and raw materials. When combined with another term, such as "medical technology" or "space technology", it refers to the state of the respective field's knowledge and tools. "State-of-the-art technology" refers to the high technology available to humanity in any field.
Technology can be viewed as an activity that forms or changes culture.[6] Additionally, technology is the application of math, science, and the arts for the benefit of life as it is known. A modern example is the rise of communication technology, which has lessened barriers to human interaction and, as a result, has helped spawn new subcultures; the rise of cyberculture has, at its basis, the development of the Internet and the computer.[7] Not all technology enhances culture in a creative way; technology can also help facilitate political oppression and war via tools such as guns. As a cultural activity, technology predates both science and engineering, each of which formalize some aspects of technological endeavor.
