Unit 3 Unit 3 Internet BasicsInternet Basics

Introduction• Do you always believe everything you hear? • Is it possible for humans

– to be biased – or to misinterpret something?

• All information sources need to be evaluated – and this is even more important when using information from websites

• because the Web has no system of quality control. • So you need to do some detective work when you are doing research;

– such as considering the motives – of people publishing on the Internet – and getting clues from URLs.

Introduction• At the end of this lesson, student will be able to:

– Critique Internet and digital information for validity, accuracy, bias, and current relevance (ACOS 10)

Lesson• Remember that on the Web anyone can publish anything

– and that the Internet is volatile meaning ever-changing. • So pay close attention to the source of any information you find on the

Web. – For instance, for facts on ancient Egypt, a site created by National

Geographic will be more reliable than a site put up by someone who’s writing about their vacation at the pyramids.

Lesson• Who has the tremendous task of monitoring the vast amount of

information found on the Internet? – To find out, watch Intel Education: Information on the Internet.

• Take a screenshot at the end of the video.– Save it to your F Drive in your Unit 3 Folder as

Lesson• Three’s the magic number. • We tend to remember items that are in groups of three better than any

other grouping, that’s why your telephone number and social security number have three parts to them.

• For evaluating web sites, remember CAP

• Currency• Authority• Purpose

Lesson• A university library tutorial added two more words—relevance and

authority. – They sum up all the evaluation points to consider when choosing

information sources as:

• Currency• Relevance• Authority• Accuracy• Purpose

Lesson• Visit this website now to learn more about the importance of evaluating

web sites: Tutorial for Info Power.– you only need to work through the investigating, searching, locating,

and evaluating sections.• Take a screenshot after you finish the evaluating section

Side Trip• When searching the Internet, you have to be a detective to look for clues as to

whether or not a website is credible. – So, now let’s test your detective abilities:

• Your “For Fun” activity is to figure out who is the owner of each pet, and where the pet got lost.

– Here are your clues: » A rabbit and a dog are two of the lost pets. » The pet lost in the garden is owned by Mary. » Robert does not own a dog. » John's pet was lost in the woods. » The cat was not lost in the woods or in the park

Side Trip• Here are some strategies for solving logic problems:

– I. Read the complete problem: Get a general idea of the problem.

– Here we have 3 owners, 3 pets, and 3 locations. – You are being asked to match each pet with an owner and a location.– A 3×3 table, also called a logic matrix, can be used to organize this

information.

Side Trip• Here are some strategies for solving logic problems:

– II. Make a list of the members of each category: Owners: Mary, Robert, John Pets: rabbit, dog, cat Places: park, garden, woods

Side Trip• Here are some strategies for solving logic problems: • III. Start filling in the table with information given in the clues.

The clues may provide direct or deduced information and can be processed in any order.

• We start by putting the owner names in the top row. • Here’s an example to get you started using clue number 2: • Clue #2. The pet lost in the garden is owned by Mary.

Owners Mary John Robert

Pets

Places garden

Side Trip• Figure out the rest of this logic problem by completing the table on the

previous slide.– Open Microsoft Word and Insert a Table with 4 columns and 3 rows.

• Your Table should look like the table on the previous slide– Complete the Table

Review• Remember to choose your sources wisely.

– Try to select sources that offer as much of the following information as possible:

• Author's Name• Author's Title or Position• Author's Organizational Affiliation• Date of Page Creation, and • Date Last Updated.

Review• When you are deciding whether or not to use an Internet resource,

consider:– Currency- is it an old or new website and when was it last updated?

– Authority-who is the author and what is his/her credentials?– Purpose-is the purpose of the site to promote an organization, to sell

something, or is it purely informational?

Task

• Your mission is to evaluate three websites on a subject of your choosing as long as it is school-appropriate.

• Conduct an Internet search on a specific topic and pick three websites. • For each of these sites, use the Evaluating Web Sites form to answer the 10 questions about

each site. • When you are finished, then rate the three web sites as to which one is most accurate and

informative with 3 being the best and 1 being the worst. • Save to your F Drive in your Unit 3 Folder as
