In recent speeches at Republican fundraisers, President Bush has taken to criticizing the press for baring government secrets. The outgoing secretary of the Treasury, John Snow, in what may have been his last official act, wrote to The New York Times that in exposing the monitoring of bank transfers, it had undermined a successful counterterrorism program. A house resolution, passed by a party line vote, called on the media to safeguard classified programs. The government has discovered what governments have discovered before, that an undercurrent of hostility towards the news media runs through the country and that there could be political advantage in campaigning against the press in general. The champion press hater, of course, was President Nixon, who told his staff that the press is the enemy, and he proceeded to declare his own private war against the media. In 1969, he had a speech written by speechwriter Pat Buchanan denouncing the media as a "tiny and closed fraternity of privileged men". And he gave it to Vice President Spiro Agnew to deliver. That speech is best remembered today for the line contributed by another speechwriter, William Safire, about "nattering nabobs of negativism". It is not clear that the public hates the press as much as officialdom would like to think. A recent Pew Research report found that public attitudes towards the press have been on a downward track for years. Growing numbers of people questioned the news media’s patriotism and fairness. And yet most Americans continue to say they like mainstream news outlets. And so, as The Christian Science Monitor headlined the other day: "Amid war on terror, a war with the press." You would not expect that I, as a journalist, would exhibit total neutrality in such a war. And so let me quote Justice Potter Stewart in his opinion in the Pentagon Papers ease in 1971: "In the absence of governmental checks and balances present in other areas of our national life, the only effective restraint upon executive policy and power in the area of national defense and international affairs may lie in an enlightened citizenry... Without an informed and free press, there cannot be an enlightened people;" That remains true, even when Mr. Bush proclaims a state of war with the terrorists. What’s the best title for the passage.

There are many benefits to using online distance learning environments. Online education is available any place, any time for global communities of learners based on shared interests. Online education with its group-based instruction and computer mediated communication provides an opportunity for new development and understanding in teaching and learning. Computer mediated communication encourages collaborative learning by not providing cues regarding appearance, race, gender, education, or social status, bestowing a sort of anonymity to participants. Distance also permits the expression of emotion (both positive and negative) and promotes discussion that normally would be inhibited. Yet, this same text-based positive aspect of online learning makes online education more cumbersome and therefore takes more time than face-to-face learning. In addition, the sheer bulk of messages can be overwhelming. The learner 0nly has the written text and no other non-verbal cues. This may confuse the learner and cause misunderstanding. Some students are not willing to take the time to go in and look up homework assignments and other online learning activities. ESL students shy away from online classes. They have expressed fear of having their work, viewed by others. In the road to dotcom in education, educators "have to slow down from their busy lives to be free to focus first on connecting with learners and connecting them to learning before they end up feeling like they are no longer using technology, but are being used by it". There is pressure to keep up with the times as well as "a cost-of-entry issue regarding technology in education. Without a certain level of technology services and learning options, many students will not consider attending a certain institution". Mark Milliron claims that "any technology has to prove that it will ultimately improve or expand learning". This will come about if educators "slow down, look around, and get on the road to dotcom—a place to thoughtfully engage and explore all aspects of technology, good, bad, or indifferent... A place with mindful focus on the people and passions that make life worth living". Should online learning be an issue of control or should students be convinced of its value as an authentic learning tool Fear and a threatening environment don’t enhance learning according to brain-based learning research. "How students feel about a learning situation determines the amount of attention they devote to it." "Positive emotions ensure that learning will be retained." It’s very. important to discuss with students how they feel about technology and online learning so that they feel good about what they are doing. The process of implementing online distance learning is a slow and delicate one. Change will eventually come about but it will take time. Sometimes online distance learning can be a problem because ______.
