users of information

What are “Power Users of Information and Communication Technology”?

Power Users of Information Technology are natives of our digital society who break out of traditional learning confines, demographic and technological barriers. Constantly using, sharing, and changing information in creative, innovative, and unintended ways empowers them to become force multipliers in their own environments. Often, they are youth (aged approximately 7-17) who have had intensive, ongoing experiences with technology, usually beginning early in life. These individuals have internalized the logic of technology systems, resulting in a level of comfort with technology that allows them to bypass many traditional learning systems. They play, explore, and experiment with technology to deepen their skills, solve problems, and create

sources of information


Information source

From Wikipedia, the free encyclopedia
"Source" means the origin of something. An information source is a source of information for somebody, i.e. anything that might inform a person about something or provide knowledge to somebody. Information sources may be observations, people, speeches, documents, pictures, organizations etc. They may be primary sourcessecondary sourcestertiary sources and so on.
Different epistemologies have different views regarding the importance of different kinds of information sources. Empiricism regards sense data as the ultimate information sources, while other epistemologies have different views (cf., source criticism).

[edit]In Library and information science

Library and information science is a field devoted to help users find relevant information sources and to organize information.
Examples of works made in order to help users identify relevant information sources are:
  • Adams, Stephen R. (2005). Information Sources in Patents. 2nd ed. K. G. Saur. (Guides to Information Sources)
  • O'Hare, Christine (2007). Business Information Sources. Library Assn Pub Ltd.

good and poor information


There is a tremendous amount of useful, factual information available online. Unfortunately, it's also very easy to find incorrect or misleading information when searching online.
It can be quite difficult to determine whether the information you find on the internet is good or bad. Lots of incoherent information is posted every day by people simply looking to jump ahead in the search engine rankings.
Have you ever read through an entire article or website, only to realize that you have more questions than you did when you started? You've probably stumbled upon some poor information in your time using the internet. There are different kinds of incorrect information available online; read on to find a description of these different types.
Intentionally Misleading Information - If you've browsed Wikipedia for a fair amount of time you've probably came across a page that was locked. This happens often when celebrities are are involved in scandals or when they pass away. Some of the comments you may encounter are totally inaccurate, while others might be controversial and subject to argument on both sides of the issue.
Wikipedia's administrators lock pages when there are too many edits coming in that present false information. This is especially common for the pages of celebrities with poor reputations, which often have derogatory information posted on them. Visit the page of a controversial celebrity and look at the edit history; you'll almost definitely see some of these edits. This is one of the negatives that come with user contributed sites, and these things must be screened carefully when the open source frameworks permit such easy access by the general public.
Unintentionally False Information - Everywhere you look online, you'll find someone claiming to be an expert and sharing his or her secrets. While they may not be trying to intentionally mislead you, they're often not 100% correct.
Always question the claims of any self-proclaimed experts online. You can double-check the facts behind their statements to be sure that what they're saying is truthful. Most of these people are simply trying to make money, and even though they may not have any malicious intent, the end result still has you believing false information.
Despite all of this, don't be scared to find information online. There's still a huge amount of useful information that can be found on the internet; you just have to do a little extra research sometimes and try to stick to reputable sources. Stick with these sources and more likely than not, you won't be mislead.
