Blog Reflection

Using your favourite metaphor, describe the most important lesson that you had learnt in your EIR journey.


The most important lesson that I had learnt in EIR lesson is to learn what is advanced search and how to use it. An advanced search give user an advance option to search more detailed for the results by minimizing the search options. Advanced search option provides a lot of options for the user to select to search more accurately and have more relevant results. Advanced search also gives users some different ways for searching and users can choose the best way to search their topic.
Now, I Write a paragraph summarizing my findings on my research topic.
My research topic is -- "Impact of online gaming on youth ". As we all know that online gaming is a hot issue, it is becoming the most popular activity around the world, especially with youth. Online gaming has both harmful and beneficial effects. If people use the right way and attitude to approach online gaming, they will avoid the harmful effects, and thus make online gaming become more beneficial. Youth is the future's hope, so we need pay more attention on them.

Blog Reflection~!

Let me share what i have learned when I am using different search facilities to search for resources related to my topic: The three search facilities, Google, Metacrawler and Yahoo Directory are equally useful as a search engine. The similarities of the three search engines are that they use a short period to search the results. It is fast. The users can search with the keyword. All of them have a sponsored listing for each result and give the number of results to users. These three search engines have advanced search, it helps the users to search with more convenience and accuracy.


However, they also have some differences. For my topic (impact of online gaming on youth), Google can find 2,010,000 results in 0.23 seconds; Yahoo directory use 0.36 second find about 494 results for the topic; Metacrawler only find 52 results for the topic and do not show the period of searching time. From these data, we can find that Google has a wider range of search results and short searching period with regard to my topic, it gives me more choices; Yahoo and Metacrawler have minimized search results. I only choose Google and Metacrawler for my search engine, because I can only find useful results for my topic in these search engines.

There are other differences of the three-search engine. Yahoo directory has related directory categories, but Google and Meta search engine does not. Users can select the categories to know more information about the topic. However, Google and Meta search engine give different types of searches, such as web, video, but yahoo directory only can search in the directory type. Meta search engine gives the users preferences for searching, and gives the results from all the other search engines. Google and Meta search engine give the users similar results of topic, it can help the user search more information about the topic.

I am very like to collaborating on wiki with my classmates who share similar research topic as me. Because I find when we sharing with each other, we can find more information about my topic and I can learn different opinions from different views about my topic.It is a very good way to learn more and make my presentation better.
