Peripherals

Peripherals are divided into two types - things that take information and put it into your computer, and things that take information out of your computer. These are called input and output devices.

Twitter quickstart

Hashtags Some times when you are watching twitter streams, you will

see “#” in front of a word or word group, such as:

This is known as a hashtag.

What does a hashtag do

Hashtags act like keywords for tweets. Twitter can search tweets,

and phrases with hashtags are marked by users to make them easier to find.

Take a look at one example:

People who want to participate in this conversation type the hashtag and the title.

You try:

Work with a partner (2 people!) Think of a place around school that has GOOD or BAD

food. Use #cycuFood in your tweet.

After you have submitted your tweet, you can click on the hashtag or type it into the search box.

Retweets

Sometimes someone that you are following writes something you would like to share with people who might not be following them.

For example, Susan

follows Avril Lavigne.

She sees a new tweet

from Avril, and wants

to share it with her

friends.

Retweeting

To share something that she sees with people that are following her, she can retweet it:

That way, people who might not be following Avril Lavigne can read what she has to say.

New Twitter Assignment

Find a celebrity, follow them, and retweet something they say ONCE. Try to make sure what you retweet isn’t too stupid - some celebrities can be pretty stupid.

Wikipedia

By now, everyone has probably heard of Wikipedia. But did you realize that it is one of the most popular social media websites online?

Wikipedia was started in 2001 by Jimmy Wales and Larry Sanger.

Wikipedia is written in over 260 different languages. The word wikipedia comes from wiki (shared

website) and pedia (encyclopedia) The English language version of wikipedia contains

nearly 4 million articles.

Wikipedia

Anyone can edit or create articles on Wikipedia. If you see something in a Wikipedia article that you disagree with you can report it or even change it.

Wikipedia has no ads - it gets the money it needs to operate by asking for donations.

Wikipedia is currently the sixth most popular website online.

Some teachers don’t allow Wikipedia articles to be used in research, but recent studies show that it is nearly as accurate as any popular encyclopedia.

Sourcing guidelines for online materials

When you are looking for information online, you need to be able to cite (引用 ) the article correctly.

There is more than one way to cite the information you find online. Below are three of the most commonly used styles used in academic writing. They are:

Chicago style - http://www.chicagomanualofstyle.org

American Psychological Association (APA) - http://www.apastyle.org/

Modern Language Association (MLA) -

For most of you, MLA style will probably be the most commonly used. However, CHECK with your teacher BEFORE you write any papers as to what citation style they prefer.
