A BRIEF HISTORY OF THE INTERNET
1966
1990
The NSFNET (National Science
Foundation Net) was created. As they
continued to improve on ARPANET’s
technology, this high speed network
became what is known as the Internet
(Banks, 2008).
The World Wide Web was created
by Tim Berners-Lee, a British
computer scientist. The first
publicly accessible website was
created in 1991 (Banks, 2008)
1995
Lawrence G. Roberts planned the
ARPANET, a computer network for
military use. Two years later BBN (Bolt,
Beranek, and Newman) was awarded
the contract to build the ARPANET
(“DARPA Achievements,” 2008).
1985
1972
1957
The U.S.S.R. launched Sputnik,
Earth’s first artificial satellite.
In response, the U.S. formed
the Advanced Research
Projects Agency (“DARPA
Achievements,” 2008).
Ray Tomlinson of BBN created the
first email program. In the following
year, Vinton Cerf and Bob Kahn
began developing TCP/IP, the
protocol used by the internet today
(Young et al., 2002).
Corporations created websites to
reach the huge market of web users,
which numbered
Over 30 million at

Parts of a URL:

PATH TO DOCUMENT

FILE NAME

• The term “URL” is an abbreviation for niform
esource ocator.
• Every web page has a unique URL.
• Every web page also has a unique
,
which is a series of numbers separated by
periods.
• URLs were developed because most people find
words easier to remember than a string of
numbers (Wing, Whitehead, & Moran, 1999).
• For example, which of the following would
rather type into an address bar?
– facebook.com
173.252.110.27?
– google.com
74.125.134.102?

advanced troubleshooting.
Problems and Pitfalls
The internet is a virtually unlimited educational tool. However, educators must
be aware of the problems and pitfalls that can occur with internet use in the
classroom:
• Access to
– Most schools have filters and firewalls in place to keep
students away from inappropriate or objectionable materials. However, do not forget
another important tool that helps to keep students on the correct websites: Adult
supervision.
– Schools also have protection in place against the use of social
media, but students and outsiders can sometimes access them using proxy servers. A
child’s internet use should be closely monitored at school and at home.

• It is recommended that teachers have a back up lesson prepared; otherwise, a
could rob you of valuable instructional time.
• The vast amount of information readily available on the internet has made

easier. Teachers must be aware of these potential pitfalls and
take steps to prevent them (Roblyer & Doering, 2010).
