WORKING WITH ONLINE SOFTWARE AND CLOUD COMPUTING

Cloud Computing

What is Cloud computing?

There are a lot of different definitions of cloud computing. Let’s use some easy ones.

Cloud computing is when you work and save files online.

You can use the files and software from any computer connected to the internet.

What’s the point?

As computers get smaller and faster, why should be bother with working and putting our documents online?

There are five major advantages to working online:

1. Shareable2. Efficient3. Portable4. Flexible5. Automatic

Show me an example

The internet is full of examples of cloud computing. Here are just a couple:

Facebook - you update, change, and share personal information online. Almost nothing is stored on your computer, and you can use it from any computer.

Dropbox - online storage that you can open from any computer. Save your files online so you use them anywhere.

Flickr - photo website where you can post your pictures for others to see and comment on.

Sounds good - what’s the downside?

Of course, with all of the advantages of cloud computing, there must be some disadvantages.

What makes cloud computing so great is also what makes it a problem - it’s online. That means “no internet, no workie”.

Security is another problem. Because your files are online, it is possible that someone other than you can use them.

Both of these issues are important, but as we become more and more connected to the internet, it’s easier to get online anywhere. Also, the companies that run cloud computing applications have to work very hard to make sure that their customers are happy - that means that the have to keep your files safe, or you won’t use them. They have a very strong reason to keep your files safe.

Working with Google Docs

One of the most commonly used cloud computing systems is Google’s email - Gmail

Let’s get started using cloud computing by making a survey in Google docs.

If you have a gmail address, go ahead and log in. If you don’t, get one at: mail.google.com/mail/signup

Let’s make a survey

We’re going to make a survey using Google Forms and Google spreadsheets

Make a simple, five-question survey inside Google docs.

Google docs uses your gmail account username to create documents.

You can use text questions, check box questions, multiple choice questions, and scale questions.

Start with a Form

From your gmail page, click on the “documents” button on the top.

Click on the Create button on the left-hand side, and select “Form”

Title your survey

Once you click Create, you will be presented with a blank form you use to enter your questions.

The first question will be a multiple choice question.

Write a question, and click on the dropdown box and choose “multiple choice”.

Add a checkbox question

Be sure to click on the pencil icon to edit questions.

You can also click on the pencil icon for questions you’ve already written to see how they will appear in your final survey.

Move your mouse down to where it says “Question 2” and click the pencil icon to write another question. This time, choose “Checkboxes”.

Click on the “Add item” button on the top left of the page and select the next question - “Choose from a List”

Add a list question

List questions use a dropdown list of choices. They are pretty much the same as multiple choice questions, but they use less space.

Add the different answers you want into the list of questions.

Click on the “Add item” button on the top left of the page and select the next question - “Scale”

Add a scale question

Sometimes called “Likert Scales”, scale questions allow you to check answers within a range that you can set.

Add a question that asks people to make a choice between two extremes.

Click on the pencil icon to see how your question will look in the final survey.

Add a Graph question using “Add item”.

Add a graph question

Graph questions can provide a range of answers to several related questions.

Remember:

Columns go UP and DOWN Rows go SIDE TO SIDE

Make a general question title, and then choose how many choices you want from the “columns” dropdown.

Once you’ve finished

There are several ways you can view and let people know about your survey.

You can email your survey by clicking on the “email this form” button on the top right of your form.

You can also view your finished survey by clicking on the link at the bottom of the questions.

Today, you can twitter me and I will retweet your link to everyone else in the class. They will take your survey.

Checking feedback

You can see how people are responding to your survey from the “See responses” button at the top right of the form.

You can view answers to your survey in either summary formatting, or spreadsheet.

Summary view automatically creates charts and graphs for easy viewing.

Your turn

Work with your group to create your own survey.

Work with your group to create a survey of five or more questions. You can write about what interests you, but please ask responsible questions.

When you are finished, tweet your link to me, and I will retweet it members of this class. They can take your survey, and you should be able to view their answers.
