The first educational technology was writing, and like every subsequent educational technology, it had its critics. Plato, most famously, denounced the medium for its inability to recreate the give and take of spoken discourse. Writing is analogous to painting, he has Socrates argue in The Phaedrus (a text that, fittingly, depicts an intimate conversation between teacher and student).1

"The painters’ products stand before us as though they were alive, but if you question them, they maintain the most majestic silence. It is the same with written words; they seem to talk to you as though they were intelligent, but if you ask them anything about what they say, from a desire to be instructed, they go on telling you just the same thing forever" (1961, p. 521).

In short, Plato holds that the technology of writing has the power to destroy the dialogic relationship that ought to occur between teacher and student. As he sees it, the medium in which we communicate determines the quality of our interactions. But this is a deeply flawed view, as many contemporary scholars have argued. Rather, the social impact of technology depends on how it is designed and used. Writing can lend itself to ongoing dialogues between teachers and students, and speech can easily become one-sided.

However, while Plato may have made an unfair generalization about writing, his critique still had merit in at least one respect: it’s worth keeping in mind that whenever a new educational technology is introduced, we ought to be wary lest reformers configure it in a way that closes off the process of intellectual exchange. There is something about dialogue, and the active involvement of the teacher, that is fundamental to the educational process and that must be woven into the design of any new instructional tool.

The Deskilling of the Teacher?

In fact, this ideal has inspired many educators since the early 1980s, and considerable progress has been made in using computer technology to develop new forms of dialogic interaction among teachers and students (Harasim, et al., 1995: chap. 3; Berge, 1999). On-line distance learning, in particular, holds tremendous promise in this regard, offering the potential for great improvements over previous models. Correspondence schools, for example, have always achieved some success at using the mail to maintain written interactions, but the process is slow and unwieldy. With the Internet, for the first time, we have an educational technology that supports rapid and convenient communication, and there’s every reason to think that Socratic dialogue can flourish in this medium. 

Unfortunately, though, the current rage for computerized instruction tends to emphasize a quite different set of possibilities for the Internet. We have seen a new round of interest in "teacherless education," or the automation of key parts of the teaching-learning process. Neither television nor stand-alone computers ever managed to accomplish this feat, but many believe that such possibilities wait for us just a few miles down the information superhighway.

To the extent that earlier attempts failed for purely technical reasons, the Internet does show promise. In its ability to transmit graphically exciting materials, programs, and text, it represents a considerable advance over earlier means of delivering information. It can even offer crude imitations of teacher-intensive tasks, such as answering questions using FAQs (Frequently Asked Question lists) and "Ask the Expert" help programs. "Intelligent agents" can adapt computer-based programs to students’ learning styles (Kearsley, 1993). And, incredibly enough, it may even be possible to automate the grading of essay tests, as Peter Foltz and Thomas Landauer claim in describing their "Intelligent Essay Assessor," based on a technique called "Latent Semantic Analysis" (Foltz, 1996). According to a Coopers & Lybrand white paper, this kind of software will soon have a radical impact upon the daily realities of higher education. "[A] mere 25 courses" of packaged instructional software could handle 80% of enrollment in core undergraduate courses; a 24-hour help desk would add a personal touch (Coopers & Lybrand, 1997).

Why would we want to automate highly skilled educational tasks? Some may argue that technology can deliver certain kinds of education more effectively than can faculty. Others would claim that automated instruction offers "consumer-friendly" options for working adults. But in the final analysis, the main reason for automating is obvious: to cut costs. Skilled workers are expensive, and automation is a time-honored strategy for reducing the need for them. The story begins in the early 19th-century, when textile manufacturers in northern England discovered that they could lower costs by mechanizing and replacing skilled with unskilled labor. The whole history of the Industrial Revolution is dominated by this strategy.

Here is how the 19th century "philosopher of manufactures" Andrew Ure described the goal in 1835:

"By the infirmity of human nature it happens, that the more skillful the workman, the more self-willed and intractable he is apt to become, and, of course, the less fit a component of a mechanical system, in which, by occasional irregularities, he may do great damage to the whole. The grand object therefore of the modern manufacturer is, through the union of capital and science, to reduce the task of his work-people to the exercise of vigilance and dexterity" (p. 18).

Attempts to similarly de-skill teaching have never been very successful in the past, but many observers are beginning to believe that new technologies can do the trick. Perhaps it will be possible to create a system whereby a variety of educational tools are delivered over the Internet and supplemented by the recorded performances of a few star professors. Then, low-level staff will perform the last few remaining tasks, such as notifying students of the availability of materials or of tests and deadlines.

Is such a gloomy version of the future really plausible? Is it likely that "self-willed and intractable" professors will disappear as have weavers, shoemakers, and typesetters? Probably not, but whether our uses of technology are about to lead to the wholesale deskilling of the professoriate is less important than the fact that this idea occupies a key place in the imagination of some educational reformers. Much of today’s reform rhetoric, with its appeals to the revolutionary potential of virtual universities and competency-based degrees, hints at the obsolescence of the traditional campus and its teaching methods, arousing suspicion among faculty that technology will be used against them. Perhaps this is what is most at stake in our present debates about the computer’s role in shaping the future of higher education: in making plans for the use of our new media, do we threaten to delegitimate faculty’s control of the educational process?

A Third Way for Educational Technology

Ironically, contemporary thinking (if not always practice) in the business world has long since left behind the industrial era’s fascination with deskilling. Over the last two decades, a good deal of business literature has been devoted to exploring a third way, an alternative to the old opposition of "man" vs. "machine." Starting with Peters and Waterman’s 1982 best seller In Search of Excellence, Frederick Taylor’s old model of de-skilled labor and hierarchical management was blamed for everything that ailed American business. The lesson has been hammered home in dozens of similar books since then.

Harvard business professor Shoshanna Zuboff made a particularly persuasive contribution to the field with her book In the Age of the Smart Machine (1988). As she sees it, we can continue to de-skill and automate production, or we can choose to take a new path, one that leads to what she calls "informating," or the cooperation of skilled workers and computers in ways that enhance the productivity of each. Zuboff’s work emphasizes the complementarity of human and computer capabilities. While humans are best at dealing with unexpected situations and responding to novelty, computers can organize the vast amount of data required by modern production processes. A similar complementarity is at work in education: the teacher manages the complex and unpredictable communication of the classroom, while data is delivered in textbooks (and now by computers as well).

Zuboff’s view contrasts sharply with technological determinism, the belief that innovations cause unique patterns of social change. The determinist view is increasingly challenged in technology studies by social explanations of technological development (Pinch and Bijker, 1987). We now believe that innovations confront us with a choice, not a destiny. The computer is certainly a case in point.

Not long ago, computers were assumed to be mere calculating and information storage devices, and their occasional application to other arenas seemed irrelevant or wasteful in the eyes of most programmers. It was only in the 1980s that electronic communications exploded, first in France, where the Minitel system quickly attracted millions of users, and soon afterwards on the Internet. It was mainly non-professionals (or professionals not associated with the design and management of the systems) who pioneered such uses of the new electronic technologies. And they succeeded because ordinary people wanted computers to serve their personal goals and not just the official functions emphasized by experts (Feenberg, 1995; chap. 7).

Just twenty years ago, few imagined what the future would hold for apparently trivial applications such as email. But it seems obvious today that the computer serves as a vital medium of communication, and not just as a calculating and information storage device. Its definition has changed in a direction determined by a social process. And the story is not yet over. The computer is not yet a finished product. It is still in flux, its evolution subject to a wide range of social influences and demands.

The specifics of the business literature are not always directly relevant to colleges and universities, but Zuboff and others’ emphasis on technological choice is right on the mark. Unfortunately, though, higher education hasn’t entirely gotten the message. Many college presidents continue to sell their constituents on the inevitability of computerization, as though the very existence of these new devices sets the reform agenda in some clear-cut and unambiguous way. And there still exists plenty of faculty opposition to the supposed consequences of the new media, as though their impact were pre-determined (Feenberg, 1999; Farber, 1998).

In reality, though, our technology does not determine whether teaching will be automated or informated. Technology by itself does not hold such power. On the contrary, we must ourselves make the decisions that will steer the future development of educational technology. And this is precisely why it is so very important for higher education to include a wide range of actors in technological design (Wilson, 1999). Students and faculty bring a number of considerations to the table, including the desire to create tools that support human interaction, a desire that has already manifested itself forcefully in the earlier evolution of the computer. To resist the automating trend in education is not simply to wallow in an old-fashioned Mr. Chips sentimentality. Rather, it is to make a case for a potential and important line of technological development. The danger is that we might listen so attentively to our technology gurus that we end up ignoring these other voices.

The Promise of On-line Distance Learning

The need for alternatives to automation may be most pressing in the field of online distance learning, a field that I helped to create in the early 1980s (Feenberg, 1993).

The origins of distance learning lie in the old-fashioned correspondence course, which feeds written documents to isolated students studying from their home. Given the economies of scale in the production of written documents, this model yields tremendous cost savings when compared to classroom education. Essentially, labor costs approach zero as the school acquires a body of reusable materials. But note the social condition for these economies: the isolation of the student.

The Internet promises to raise the level of correspondence education, and it promises to do so inexpensively, by improving the materials available to the student. Not only does it replace the Post Office, television, and radio as means of delivery, but it can also carry out new tasks, delivering film, audio, and automated educational programs quickly and conveniently. However, the Internet can do more than merely improve the traditional correspondence course; it can also be used to add human contact to an educational model that has always been relatively impersonal. Using email and computer conferencing, groups of students can be assembled in online communities where they can participate in classroom discussion with teachers on a regular basis.

There are two alternative models of on-line distance learning here with quite different financial structures. An automated system takes advantage of the economies of scale associated with the distribution of written materials and extends them into the wide range of media supported by the Internet (Agre, 1999). On the other hand a system that also includes live interaction does so at a price: a qualified teacher must be in attendance at every iteration of the course. Institutions may save money on building costs but not on educational labor, the single largest item in most university budgets.

There are further implications for the design of courses. Automated products will tend to be quite elaborate, since they must rely entirely on the computer to dramatize their message and motivate the student. Courseware designers and producers will manage the work of star faculty who can offer a polished performance in the new medium. Predictably, educational technology will evolve to Hollywood levels of complexity.

By contrast, courses animated by a live professor will generally be designed under his or her control in relatively simple and flexible formats. No computer professionals need be involved. As in the conventional classroom, much of the interest of the product will lie in the interaction among students and between students and teachers. As far as techniques of presentation are concerned, a certain healthy amateurism is to be expected. Prepackaged computer-based materials will not replace the teacher but supplement his or her efforts, much as do textbooks today. Software designers will pursue user-friendliness and simplicity to serve faculty needs.

In sum, the field of on-line distance learning faces precisely the same choice between automating and informating that businesses face as they confront the challenge of the computer. And, surely, we ought to make this choice on educational grounds.

Shaping the Future of Educational Technology

We already have a base of experience with interactive forms of on-line education, and the evidence seems clear, at least to those who have tried it: written dialogue works. Using computer conferencing software, faculty in many universities have for years now been working to bring the excitement of classroom discussion to an electronic setting. Such on-line discussions are not the same as face-to-face interactions, of course, but they have their own advantages. For the instantaneous back and forth of real-time discussion, they substitute a slower but still engaging day to day rhythm. With time to think and compose questions and answers, students who might never have participated in a face-to-face setting bring forward their ideas. The use of writing imposes a discipline and helps focus thinking. Faculty learn to grasp students’ ideas at a much deeper level as they engage with them on line. Innovative pedagogical techniques such as collaborative learning have been adapted to the Internet and new forms of interaction invented (Harasim, et al., 1995: chapter 6). From an educational standpoint, there is little doubt that competent teachers under these conditions can be effective at sustaining a true equivalent of classroom interaction.

But in shaping the future of our technologies, economic and political realities now look to play the leading roles. Higher education seems increasingly enamored with corporate rather than professional models of organization. The erosion of traditional faculty status continues apace in innovative institutions serving adult learners, now half the students in higher education. Even the older universities that now teach a declining fraction of students employ more and more part timers in the search for "flexibility." And it is becoming more difficult to resist arguments against tenure, arguments that carry conviction with the public if not with most members of the university community. In short, there exists a great deal of temptation to think of technology as a managerial tool for centralizing the university. And if we are not careful, something like this may actually happen in the confusing environment created by technological change.

Fortunately, how we design our new technologies is still an open question; the answer will decide which benefits and which limitations we end up with. Indeed, that choice will decide who the "we" are that peoples the educational institutions of the future, since our models of computerized instruction will define the future identities and roles of students and teachers. If we can resist simplistic appeals to managerial efficiency and focus our efforts on sustaining the dialogue that has always been at the heart of the educational experience, then technology holds great promise; if not, then we face a great threat

How come? 为什么? (怎么会这样?)
How come 的用法大部分就等于 why ,但是它的用法没有像 why 那么广, 它通常是用在你觉得奇怪, 而问为什么的时候, 比如说有人早上一大早要去 supermarket 你就会问他.  "How come?" 另外, 当别人问你一个问题, 而你不想回答时可以说 "How come?" 相当于, "Why do you ask that?" 也就是说 "It’s none of your business! "虽然 how come 跟 why 的用法上差不多, 但二者的问法不同, 例如上句, "Why is our oven broken?" 换成 how come 的话, 要说成, "How come our oven is broken?" 注意一下, 这二句的 be 动词位置是不一样的。


A Sioux Indian story …
My grandfather took me to the fish pond on the farm when I was about seven, and he told me to throw a stone into the water. He told me to watch the circles created by the stone. Then he asked me to think of myself as that stone.
"You may create lots of splashes in your life, but the waves that come from those splashes will disturb the peace of all your fellow creatures," he said.
"Remember that you are responsible for what you put in your circle and that circle will also touch many other circles."
"You will need to live in a way that allows the good that comes from your circle to send the peace of that goodness to others. The splash that comes from anger or jealousy will send those feelings to other circles. You are responsible for both."
That was the first time I realized that each person creates the inner peace or discord that flows out into the world. We cannot create world peace if we are riddled with inner conflict, hatred, doubt, or anger.
We radiate the feelings and thoughts that we hold inside, whether we speak them or not. Whatever is splashing around inside of us is spilling out into the world, creating beauty or discord with all other circles of life.



A set of five doll mascots for the 2008 Olympic Games were unveiled in Beijing on Nov, 11, exactly 1000 days before the event’s opening ceremony. The mascots embody the natural characteristics of four of China’s popular animals—the Fish, the Panda, the Tibetan Antelope, the Swallow and the Olympic Flame.

Each of the mascots has a rhyming two syllable name—a traditional way of expressing affection for children in China. Beibei is the Fish, Jingjing is the Panda, Huanhuan is the Olympic Flame, Yingying is the Tibetan Antilope, Nini is the Swallow. When you put their name together–Bei Jing Huan Ying Ni–they say “Welcome to Beijing.” offering a warm invitation that reflects the mission of the Five Friendlies as young ambassadors for the Olympic Games.

 In Chinese traditional culture and art, the fish and water designs are symbols of prosperity and harvest. And so Beibei carries the blessing of prosperity. A fish is also a symbol of surplus in Chinese culture, another measure of a good year and a good life. Among the Five Friendlies, Beibei is known to be gentle and pure. Strong in water sports, she reflects the blue Olympic ring.

Jingjing makes children smilehe brings the blessing of happiness. As a national treasure and a protected species, pandas are adored by people everywhere. Jingjing was chosen to represent our desire to protect nature’s gifts–and to preserve the beauty of nature for all generations. Jingjing is charmingly naive and optimistic. He is an athlete noted for strength who represents the black Olympic ring.

In the circle of Friendlies, Huanhuan is the big brother. He is symbolizing the Olympic Flame and the passion of sport. Huanhuan stands in the center of Friendlies as the core embodiment of the Olympic spirit. And while he inspires all with the passion to run faster, jump higher and be stronger, he is also open and inviting. Wherever the light of Huanhuan shines, the inviting warmth of Beijing 2008 and the wishful blessings of the Chinese people can be felt. Huanhuan is outgoing and enthusiastic. He excels at all the ball games and represents the red Olympic ring.

Yingying is fast and agile and can swiftly cover great stretches of land as he races across the earth. A symbol of the vastness of China’s landscape, the antelope carries the blessing of health, the strength of body that comes from harmony with nature. The selection of the Tibetan Antelope reflects Beijing commitment to a Green Olympics. Strong in track and field events, Yingying is a quick-witted and agile boy who represents the yellow Olympic ring.

Nini’s figure is drawn from the grand tradition of kite designs– golden-winged swallow. Swallow is also pronounced "yan" in Chinese, and Yanjing is what Beijing was called as an ancient capital city. Among the Friendlies, Nini is as innocent and joyful as a swallow. She is strong in gymnastics and represents the green Olympic.

In the ancient culture of China, there is a grand tradition of spreading blessings through signs and symbols. Each of the Five Friendlies symbolizes a different blessing. Prosperity, happiness, passion, health and good luck will be spread to every continent as the Five Friendlies carry their invitation to Beijing 2008 to every part of the globe.

The Five Friendlies also embody both the landscape and the dreams and aspirations of people from every part of the vast country of China. In their origins and their headpieces, you can see the five elements of nature–the sea, forest, fire, earth and sky–all stylistic rendered in ways that represent the deep traditional influences of Chinese folk art and ornamentation.

Pam decided to call it a night after dancing for five hours.

call it a night 可能是从 call it a day 来的,call it a day 意指“今天的活动或工作到此为止(剩下的时间要用来休息)”,因此 call it a night 是指「今晚的活动到此为止」,类似的用法还有 call it quits,表“放弃;不再做事”之意。

        When we are children, it is natural to cry and get upset when we feel sad. As we get older, we begin to understand cause and effect. By understanding more about the reasons things happen, we begin to feel a sense of control over our lives, and we are less likely to get hurt. At the same time, society pressures teenagers to show less emotion (at least in public) and remain calm and reasonable no matter what the situation. 

      As adults, we try not to lose control over our emotions. There is a limit, however, to how much a person can bear in silence. At some point, the pain becomes too great to bear, resulting in tears and other signs of sadness. It is at such moments that we describe a person as "losing it," meaning losing control over their emotions. Often this is a good thing: after "losing it" a person may feel much better.
