continually updated Different search engines produce different

results Software sorts through millions of pages to

find matches (less than 1 second) Ranked in order of relevance, but websites

can pay money to be ranked up the top

Useful for transition from kids search engines to adult Specific video search engine part Uses Google, bing and yahoo to deliver more precise

results Approximately only 11.3% of the information are shared

by the 3 search engines Dogpile claims that it saves time by not needing to

research with the 3 major search engines Dogpile have completed a study that includes that;

Majority of all first results page are unique to that search engine

Eg. Google 70% By searching only Google a searcher can miss 72.7% of the

webs best first page search results

Page 17: Search Engines

Take a minute to search through Google and

Dogpile.Try searching the same thing and see which one produces better results.Ex: Why is the sky blue?

Page 18: Search Engines

Locating Information Strategies knowing the web address surfing random sites on the internet finding subject directories that contain

organised lists of information using search engines

Page 19: Search Engines

Assessing Information1. Authority2. Currency3. Accuracy4. Objectivity5. Coverage

Page 20: Search Engines

Evaluating Information Student audience – what is the age

range? Source of information – how valid and

credible is the information given? Analysis of the content

Page 21: Search Engines

Activity #1 (Students) Year 3-5 students Use a variety of different kids search engines to

answer questions Use different strategies – avoid typing the

question out, try keywords Assess and evaluate the sources of information Rate the search engines – speed, results,

physical appeal, ease of use Which one would you teach your students to

use?

Page 22: Search Engines

SHARING Which kids search engine would be top

of your list? Which search engine was the easiest to

use? Why? Was there a general consensus in

answers across all search engines? Which one is more appealing to use?

Why? Which one would you teach your

students to use?

Page 23: Search Engines

Activity #2 (Peers) Preparation for PAR 2 Lesson plan of an individual student Different experiences with ICT and varied

learning abilities Plan an individual lesson plan for that student Refer to ACARA Depending on the situation, what would you

teach them regarding the use of search engines?

Come back as a group to share

Page 24: Search Engines

Classroom Application Filter, control over results Curriculum to back-up teaching Credible sources More than Google Keywords Other reference points – library Features of search engines We should know how to use them before

teaching them

Page 25: Search Engines

ACARA By the end of Year 2: Recognise that people create information resources and

that the information they create or provide can be used or misused by others (cannot copy other people’s work)

Identify use of ICT at home and at school

By the end of Year 6: Able to name sources, avoid plagiarism, know what

may or may not be copied Check integrity of web links Plan, locate, retrieve and organise information
