2 Introduction Do you always believe everything you hear? Is it possible for humansto be biasedor to misinterpret something?All information sources need to be evaluatedand this is even more important when using information from websitesbecause 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 motivesof people publishing on the Internetand getting clues from URLs.
3 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)
4 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.
5 LessonWho 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 as3.03 Intel Education
6 Lesson Currency Authority Purpose 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 CAPCurrencyAuthorityPurpose
7 Lesson Currency Relevance Authority Accuracy Purpose 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:CurrencyRelevanceAuthorityAccuracyPurpose
8 LessonVisit 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 sectionSave to your F Drive in your Unit 3 Folder as3.03 Tutorial for Info Power
9 Side TripWhen 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
10 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.
11 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
12 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.OwnersMaryJohnRobertPetsPlacesgarden
13 Side TripFigure 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 slideComplete the TableSave to your F Drive as3.03 Side Trip
14 Review Remember to choose your sources wisely. Try to select sources that offer as much of the following information as possible:Author's NameAuthor's Title or PositionAuthor's Organizational AffiliationDate of Page Creation, andDate Last Updated.
15 ReviewWhen 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?
16 TaskYour 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 as3.03 Evaluating Web Sites Dropbox.2 search engines that you can use are below:GoGooligansTeachnology - Search Engines for Students
