…Researching
on the InternetWhat are the things we should keep in mind when we use the Internet to do research?Step one: choosing a search service
Step two: how to search
Step three: using your informationRead the information sheet about Internet research carefully and answer the following questions.
A subject directory is best search for the topics we are interested in. Subject directories are built by humans. Someone has combed through pages and links and selected all those that are in the directory. The results of your search are divided into specific categories. We do not get the full pages to read.1. What kind of search service is best for the topics you are interested in? Can you tell me the reason?2. Why should we check the date when we search the Internet?
Because we don’t want to use information that is too old.3. What is called cross-checking?If you find information you are not sure about, consult other web pages to confirm the information.4. How will you check your information and decide which sites to trust?As a general rule, we check the source of the information we find. Personal web pages are not good for doing research. Government pages, or pages managed by organizations and companies you trust are much better.5. How should we use the information found on the Internet?We should write an outline of the information we have found. Then we use our own words and make our own decisions about what it means. When we finish, we should always attach a list of the sites we got our information from. This way, a teacher can check them, and an interested friend can also read what we read.Comparison of the two search servicesThe more you know about Internet research, the faster you will find what you are looking for, and the better your information will be.
