Developing Resources for Schemes of Work

• Developing Resources for Schemes of Work

2

• Activity 1
• Find the National Curriculum Web Site
• Add this to the Favourites (Explorer)or
  Bookmarks(Netscape) for future reference
  
• Copy (CtrlC) and Paste (CtrlV) these into MS
  Word
  
• Select (Copy-Paste) onto a new page those items
  from the Attainment Targets appropriate to your
  chosen topic

3

• What are the Internet and World Wide Web?
• The Internet is a cooperatively run global
  collection of computer networks with a common
  addressing system
  
• The World Wide Web (WWW) is the graphical user
  interface of the internet
  
• Currently unregulated, rapidly commercialising,
  and accessible to the public

4

• The WWW in the Secondary Curriculum
• Used by teacher at home or school as a source of
  information for lesson content or worksheets or
  for information from educational organisations
  
• Used by teacher at school for showing during
  lesson via a monitor or data projector
  
• Used by all or some pupils for a whole or part of
  a lesson for a structured task or investigation
  (caution how do you avoid net surfing or the
  possibility of access to undesirable material?)
• Used by pupils at home or school for a homework
  task in their own time
  
• (caution how can you detect plagiarism?)

5

• Activity 2
• For general information on a broad topic try a
  directory or index based search (e.g.Yahoo)
  
• For very specific information such as titles,
  phrases or images try a search engine (e.g.Alta
  Vista)
  
• Now learn more about how search engines work at
  Search Engine Watch
  
• The following slides highlight some of the key
  points from this site

6

• How search engines work
• Most search engines use programmes which
  automatically run through all the text of pages
  on the web (except stop words such as the) to
  find matches to your keywords or phrases
• Some (e.g.Yahoo) use a system of classifying and
  indexing submitted pages
  
• Some look for Metatags inserted in the html
  code
  
• My Worldname"description" content"Everything you wanted
  to know about stamps, from prices to
  history."stamp collecting, stamp history, prices, stamps
  for sale"
• Hybrid engines (most) use various combinations of
  the above

7

• How search engines rank pages
• Location of keywords on page primarily in the
  title, subtitle or opening paragraph
  
• Frequency of occurrence of keywords
• note, however, that the search engine will
  automatically penalise or reject a site or page
  using spamming techniques such as deliberate
  flooding with strategic keywords to improve
  ranking
• Location/frequency may be augmented by the use of
  other criteria, most notably
  
• Metatags - predefined description and keywords
• Link popularity - number of hyperlinks directed
  to the site
  
• Reviews - existence, volume or quality of site
  reviews

8

• Search tips from Alta Vista
• In general, you should always try a natural
  language (keywords) query first
  
• If you need to narrow down the result use Boolean
  Logic (see module2.8), especially -
  
• The search techniques on the following slides are
  taken from the Alta Vista menu. While most can be
  used with other search engines, there are some
  variations which you can find listed at

• Now try this (activity 2.8) using a worldwide
  search
  
• Imagine that you want a recipe for oatmeal raisin
  cookies. Try
  
• oatmeal raisin cookie
• (the search engine will find pages with an
  occurrence of any one of these words note the
  number of pages)
  
• oatmeal raisin cookie
• (the search engine will only find pages with an
  occurrence of all three words note the number
  of pages)
  
• oatmeal raisin cookie nuts
• (someone in the family has a nut allergy, so
  those recipes with nuts are eliminated note the
  number of pages)

13

• Activity 2.9
• Try a search of your own. If you prefer this to
  be UK based (as often in education), Alta Vista
  allows you to click a radio button to specify
  this otherwise, you could specify domainuk
• note the results on the module 2.9 form

14

• Activities 3 and 4
• Activity 3 requires you to locate resources
  using the Encarta CD (note that some schools have
  this installed on their network)
  
• Activity 4 asks you to look at some specialised
  education web sites
  
• Step 2 show you how to add these to your
  Favourites and classify in folders
  
• Step 3 shows how to create a references page

15
Activity 4, Step 3

• Use image_ _ _ to search for sites with only
  images of your chosen subject
  
• Use the listed site descriptions to find the most
  appropriate site. Many (left) have thumbnail
  collections which allow you to choose
  
• Double click on the thumbnail to open up a full
  size version of the image

16

• To download an image right click on the image to
  get the on screen menu
  
• Click Save Picture As..
• Browse to the location where you would like your
  image saved and follow the default to save as
  either a jpg or gif file which you can use in a
  web page or in a Word or Publisher document

17

• Issues of Internet/Web Security
• There are a number of ways in which adult
  material or other undesirable material (such as
  those advocating hatred, bigotry, violence,
  gambling, etc.) can be filtered out, mainly
• Screening by the ISP or Proxy-Server (e.g. RMs
  EduWeb)
  
• Local server monitoring of the log of sites
  visited or the screening of site addresses as the
  basis for denying access
  
• Client software on local computers to either
  screen user input or filter out self-certificated
  sites through a PICS rating on individual site
  metatags
• Source material protected by password or adult
  verification service (usually meaning user
  provision of a credit card number)
  
• Establishing a school code of practice (ground
  rules can be effective to a point) and ensuring
  personal supervision where possible
  

18

• Further Activities
• Continue to locate useful resources for your
  subject and save them in the Favourites folder
  
• Try evaluating the site using the module 2.19
  evaluation form which prompts you to consider the
  authenticity of web site information
  
• Ask your school IT coordinator how about what
  system the school has to filter out undesirable
  web sources
  
• Try to share web site information within your
  method group so that you can compile a mutually
  beneficial list (-set up a group mailing list)
