2 Using Technology as a Learning Tool Thursday, January 12, 2005 Session #2

3 Class Overview Unfinished business Article #1 Review of Internet Browsers Find it easy, find it fast! – Searching strategies Getting the most out of technology Project Proposal Forms - due as an attachment next week

4 Schooling and Technology in the Information Age What is David Suzuki concerned about and what does he propose that school teachers should do to resolve it? Explain the three types of social eras that humankind has experienced, and describe what a knowledge worker is. Discuss the differences between how teachers use technology to facilitate teaching, and learning and as an essential part of a changing world (understanding technology itself) Discuss Hathaway’s four implications of planning to integrate technology into schools.

6 Explain the three types of social eras that humankind has experienced, and describe what a knowledge worker is.

7 Discuss the differences between how teachers use technology to facilitate teaching, and learning and as an essential part of a changing world (understanding technology itself)

8 Discuss Hathaway’s four implications of planning to integrate technology into schools.

9 Explore and experiment with new technologies and ask for help when you need it Eliminate as much of the uncertainty and “mystification” of technology Observe what works well for others Offer support when you can How can we learn more about educational technology?

10 What is Technology in the School Setting?

11 Technological Tools Productivity tools (e.g., Microsoft Office, AppleWorks) The Internet and Videodisks CD ROM Video-conferencing Audio / visual equipment

12 Potential Uses of Technology Allows teachers to potentially customize instruction – example: Web Quests Can eliminate time constraints and local boundaries – use of web-based technologies Provides schools with the opportunity to collaborate on projects Potential links with post-secondary, public, private, and other K-12 systems Has the potential to expand the learning process or academic success of all students

13 Addressing the Issue Technology must respond to three questions: 1. Does it make learning more accessible? 2. Does it promote or improve learning? 3. Does it accomplish the above while containing, if not reducing the per unit costs of education?

14 Impact of Internet Technology Free physical boundaries of classrooms and time restraints of class schedules Demonstrations can become Web based multimedia learning experiences Learning resources can be augmented by learning resources from the Web Re-focus our institutions from teaching to learning, from teacher to student.

15 An Overview of Explorer Title Bar / Menu Bar / Button Bar / URL / Viewing Area Status Line / Close / Restore / Minimize

16 Netscape Title Bar / Menu Bar / Button Bar / URL / Viewing Area Status Line / Close / Restore / Minimize

17 Menu Bar Features: Edit (Netscape and IE) Click Edit, then Find in Page - lets you search for text in the current page Key strokes – Ctrl - F Go (Netscape) or Tools (IE) History - keeps track of pages you have visited

18 Topics What is a search engine? How does a search engine know about things on the Net? How can I improve my use of search engines? How do I narrow or broaden a search? What’s a meta- search engine? What are some effective search strategies?

19 What’s a search engine? An Internet tool which will search for Internet sites containing the words you designate as your search terms. Provides results back to you in the form of links to those sites which include the terms you are looking for. Search engines search databases of information that have been collected by automated computer programs.

20 How does a search engine know about things on the Net? If search engine finds it while its “spiders” are out collecting data from the Web servers. The information is put into a large database that the user searches. If a publisher of a Web page registers the site with the search engine.

21 How can I improve my use of search engines? Learn how to use wildcards and Boolean operators. Wildcards allow you to search simultaneously for several words with the same stem. Boolean operators allow you to combine terms to broaden or narrow a search.

22 How do I use a wildcard? A wildcard is a special character that can be appended to the root of a word so you can search for all possible endings to that root. Example : Doing a search on whal* would return whale, whales, whaling, whalers

23 How do I limit a search? Using the Boolean operator “and” Example : The search string heart and disease will only provide links to sites that have both of these terms. Documents which have just one of the terms will be ignored. You can narrow it more by using and more than once.

24 Website Let’s visit this website to see Boolean operators in action: Title: Boolean Searching on the Internet – updated

25 What’s a meta-search engine? A meta-search engine doesn’t create it’s own database of information. A meta-search engine searches those of other engines and directories. By using multiple databases, the results are more comprehensive, but slower to receive.

26 What are some effective search strategies? When using a search engine, be a specific as possible. Try different search engines. Read the “tips” and help files that are included with most engines.

28 Search Review Subject Catalogues Recognizing Search Engines Special Search Engines More Special Tools Strategies for Better Results Specialty Engines Overview of Results

29 Subject Catalogues Collection of sites organized into broad categories or topics Sub-categories lead to sites or further categories Some are evaluated collections Classic example is Yahoo:

30 Special Search Engines Natural Language Engines Fuzzy Logic Engines guidebeam.com/ Filtered Engines

31 Fuzzy Logic Engines the engine tries to comprehend the user's search query and respond intelligently with the most relevant categories. Guidebeam doesn't pretend to "know what you mean". reduces information overload by presenting a structured summary of the search result (a "hyperindex") user can browse in order to clarify his or her information need. This engine is particularly suited for non-technical users (who typically issue imprecise queries)... searching of the type "I don't know what I want, but I'll know when I find it".

32 More Special Tools There are all kinds of special tools for locating people, places, maps, words, postal codes – you name it. The key is knowing where to find them! Many of these materials are located in what is now called “The Invisible Web” Dictionaries, Thesauri, encyclopedias, Translators… The Invisible Web Blogs Finding Search Tools

33 Strategies for better results Putting together a search strategy before you go searching will produce better results and get them faster Strategies involve selecting the rights terms, combining them together in a way the engines can use them more efficiently, and using any additional techniques that may be available to narrow down the results

34 Selecting the right terms Decide exactly what your question is Pick out a primary category the information might fall under (education, history, mathematics…) and the main keywords of the question Think of synonyms or other terms for the keywords (plurals, alternate spellings) Build a Concept Block of your terms

36 Getting a Quick Overview of Results Try a Metasearch Engine IxQuickwww.ixquick.com Dogpilewww.dogpile.com Metacrawlerwww.metacrawler.com Cjnet Searchwww.search.com Watch out for: Sites that provide ratings – how do they evaluate and who is doing the evaluations? Sites that generate results with paid listings (overture.com)

37 Combining Tools & Techniques Deciding what you want to find out Gathering the right terms and phrases Selecting the type of tool most suitable Building a good search strategy Building limitations into your search Refining your search in the selected tool Trying a Metasearch for an overview Successful searching on the Web will result from:

38 How can we get the most out of the technology? Teachers and students have to be adept users Using the computer as a cognitive tool requires that the teacher employ effective teaching strategies that are student-centred Use the technology because it does things we could not do otherwise

39 Teachers Make the Difference not Computers! Gains in achievement depend on the teacher and the strategies used by that teacher to engage children in meaningful learning The computer can assist the teacher by creating learning environments that are not otherwise possible and by providing the student with a tool to represent knowledge in different ways.

40 Technologies Impact on Methods of Instruction Teachers need training and ongoing support to help them use technology effectively and integrate it into their classroom teaching. The use of the Internet in education multiplies limited resources and helps teachers reach all students. Bracey (1996) Hubbard, (1995) sounds a negative note when he suggests that one of the greatest hurdles to the adoption of electronic methods of instruction is human inertia: that is a resistance to change

41 New Roles teachers help students to pursue their own inquiries (“navigators and drivers”) students need to make use of the new technologies to find, organize and interpret information we all need to become reflective and critical about information quality and sources.

42 Why Do Teachers Use The Internet?

43 Citing Internet Material Remember… “garbage in - garbage out”, no one has checked the value of the materials Work with your students to decide what is and what is not credible material

44 Learn the Net… on the Net! We will be visiting

45 What are Plug-ins? Add-on applications that work inside the browsers Give the WWW its punch, pizzaz and its bells and whistles Stay in the background - pop-up when needed They run audio, video and animation sequences in Web pages “richer virtual world”

46 “In the story of the Trojan horse, it wasn't the horse that was effective, it was the soldiers inside. Technology is only going to be effective in changing education if you put an army inside it.” - Seymour Papert
