Advantages and disadvantages of school children using the Internet for research

Extracts from this document.

Discuss the Advantages and disadvantages of school children using the Internet for research Over the last decade computers have been used more than ever before. The emergence of the Internet during the 1990′s allowed educational research materials to be made available through websites. Many people now use the Internet as a primary source of information for their work however there are many sides to this argument and there are doubts whether this is advisable in all cases. There are both advantages and disadvantages of school children using the Internet for research purposes, these advantages are: * The fact that the Internet is an easy tool to use and, once the child has learnt how to use the web; they can use search engines to find almost anything. . read more.

* There is a great deal of software available to stop unwanted sites, viruses or ads coming up, so the child could be trusted to use the internet without being in danger as long as they bear in mind that privacy is important and as long as they do not disclose personal information over the web. * You can get Current, topical information, such as news from around the world as the Internet is constantly being updated. * Also, there are many sites, which help children to study through the use of different media such as online Learning. Disadvantages include the fact that. * Anyone can publish a web page to support his or her own intents and purposes. . read more.

some relevant information * Not all information is on the Internet and so the subject that the particular student may be researching may have more to it than is shown. * There can be many people such as hackers etc. who are trying to access your computer whilst you are on a particular site. This is important to remember when using the Internet for anything. In conclusion, I would say that the Internet is very useful to schoolchildren (like myself) in terms of its research potential but one must be aware of its limitations and should follow sensible practise in using it safely and wisely. However certain points must be remembered to ensure that the research produced is true and realistic. . read more.

The Disadvantages of Internet in Education

The Internet has come to play a prevalent role in the professional, personal and educational lives of most people in the Western world. Since the inception of the World Wide Web, more and more information has become accessible to all people through a few simple clicks of a mouse. The world is, literally, at the fingertips of a person connected to the Internet. The question for educators and parents remains, though, whether or not there are disadvantages to utilizing the Internet in a student’s education.

Research Skills

Students in schools with readily available Internet access tend to overlook the traditional library and book method of research in favor of an Internet search. While it is important that a student understands how to properly search the Internet for reliable information, it is equally, if not more important, that a student know how to search a library and card catalog database for books, encyclopedias, primary source documents, cataloged magazines and newspapers, newsreels and other sources not available online. When assigning projects, it is important that a teacher require a majority of sources to be from sources other than the Internet.

Evaluating Information

The well-known Christmas story entitled, «Yes Virginia, There is a Santa Claus,» answered a young girl’s question about the validity of the famous mythical man by appealing to her belief that if something was printed in the newspaper, then it must be true. This same faith in «printed» material is held by students today, and often spills over into a misguided faith in the accuracy of anything posted on the Internet. One of the first things children must learn about the Internet, but that many do not listen to, is that there are scores of websites and articles on the Internet that are false and inaccurate, purely opinion, or extremely biased or slanted. Younger students often do not know how to recognize a reliable website or understand when an article contains authorial bias.

Teachers and parents should insist on guiding students to reputable websites that end in suffixes such as .org. gov, or .edu, and to avoid open forum sources of information such as Wikipedia for academic research. While it is preferable that students utilize traditional, reliable print materials in place of Internet research, they also must learn how find quality material online versus misleading information.

Parental Controls

For younger children, the Internet can be a vast sea of largely unsuitable material. While some browsers allow a certain amount of control to filter out content such as pornography and violence not suitable for young children, it is impossible to ensure a 100 percent safe search. Avoiding absolute censorship, a non-Internet based education allows parents and educators to select books, videos and material that are pre-screened and will not subject a child to age-inappropriate material by accident.

Advantages & Disadvantages of DNA Analysis

DNA testing is the process of analyzing genetic material from an individual to determine identity, susceptibility to disease and other important information. As DNA analysis becomes a more common tool in the fields of medicine and criminal justice, there are still significant drawbacks to go along with its many benefits.

Identification

One of the biggest advantages of DNA testing is its use in identifying suspects in a criminal investigation. Because each individual has unique DNA, the margin of error is very small, making it a better form of identification than fingerprints. DNA evidence from blood, skin or hair can be matched to the DNA of a suspect to determine information about where an individual was and who they may have come in contact with.

DNA analysis is especially important in cases of rape, where doctors can often examine a victim and find traces of the rapist’s DNA, which can the be compared to suspects to determine the guilty party.

Disease Screening

Another major advantage of DNA analysis is the ability to screen for certain genetic diseases or risk factors. Prospective parents can be tested to determine if they carry genes that are responsible for certain conditions that may be present in other members of their families. This may have an effect on the decision of whether or not to have children.

Women involved in certain fertility treatments can also get information about an embryo before it is implanted. This can eliminate or confirm the presence of some genetic disorders, increasing the likelihood of a safe pregnancy and a healthy child.

Privacy Concerns

One key disadvantage of DNA analysis is the potential for invasion of individual privacy. Because a person’s DNA reveals so much information about their physical state, it is sensitive information that must be carefully guarded. Concerns about employers gaining access to genetic information about employees and using it to make hiring decisions or determine health care eligibility are common. Information about an individual’s ethnic background and parentage could become cause for discrimination.

Eugenics

Finally, there are concerns that widespread use of DNA analysis could lead to the practice of eugenics, in which doctors and individuals could manipulate the gene pool by allowing only desirable genetic characteristics to be passed on to a generation of children. This type of action can be seen as interfering with nature and may run counter to some religious beliefs. The ethical questions concerning genetic modification are often at the forefront of the debate about when, and how, DNA testing should be administered.
