Google Instant - Help or Hindrance?

One of the features of Google search that I have mixed opinions about is Google Instant. This means that when you are typing a search query, predictions and results will appear as you are typing.

As a user I find it very useful and efficient, and it can offer the phrasing or search terms I was looking for and save a lot of time. But as a teacher, I wonder whether or not the pros outweigh the cons. The pros, of course, are that students are given the same efficiencies I am while searching. They can begin a query, and then if their question is listed below in the predictions, they can click on it, avoiding the need sometimes for having to spell tricky words.


It is the unpredictability of the content of the predictions that worries me. Even with strict filtering on, Google Instant can give pretty dodgy predictions, especially if a student's search query begins with the same spelling as something less savoury. Try "How to make ..." and you will see what I mean, depending on what the next words starts with.


Fortunately, from Settings at the top right of a Google page, it is a short step to switch Google Instant off.




I have put this setting on all of my students' computers for now, erring on the side of caution. In the Advanced Search menu there is also the option of selecting the reading level of results. This would be great if it were a setting that could be applied to all search results, not just individual searches.




The other option, of course, is not to use Google at all, but one of the many search engines that are designed especially for children. A favourite of mine is Kidrex, which I have linked to our class wiki, but there are others such as KidsClick (which seems to be under construction at the moment) and CyberSleuth. A great option for teaching children effective search strategies, using AND, NOT, OR and other boolean techniques is Boolify, which uses these phrases to jigsaw the search terms and narrow down the results.




What is your search engine of choice for children? Do you think I am right to switch off Google Instant for my 8-9 year olds? How do you teach your students to search safely? Please leave your comments below!

Google, the Gatekeeper and the Pacific Northwest Tree Octopus

I've been doing some reading around digital literacy for an essay due in June, and came across a great article by L.A. Henry (2006) called 'SEARCHing for an Answer: The Critical Role of New Literacies while Reading on the Internet'.

In the article she provides a great overview of a framework (SEARCH) for showing learners how to navigate such an unwieldy beast as the Internet:

1. Set a purpose for searching.
2. Employ effective search strategies.
3. Analyze search-engine results.
4. Read critically and synthesize information.
5. Cite your sources.
6. How successful was your search?

The thing that stood out to me most of all was the need to train our learners how to use a search engine (Step 2 above). I think we can assume sometimes (and our learners assume too) that everybody knows how to 'Google' something, but this is simply not the case. The results of an inefficient search strategy can be incredibly time consuming. Henry refers to this skill as a 'gatekeeper' skill in online reading:

Students who can quickly read and locate information are then able to use that information for learning and move on to other elements of reading on the Internet; students who cannot are unable to move beyond the search process. Because searching for and locating information are such critical parts of information use on the Internet, they demand our attention. (p.616)

There are a number of search tools/engines that I've found recently, that have been specifically designed for younger learners, and could be useful in helping this 'gatekeeper skill' of effectively locating information.

The first of these is Kidsclick, a website designed by librarians. They developed this to help develop the skill of locating information. It doesn't block any sites, being intended to 'guide users to good sites, not block them from bad ones.' It uses the SWISH-E search engine.

The next one I found is Ask Kids, designed for 6-12 year olds. This website is filtered, and each website in their core index was selected by their editorial team as child-appropriate and relevant. Great visual layout, and easy to navigate.

The last one I'll talk about today is Kidrex, which uses the Google search engine. This site has a page for parents with tips on how to help their children use search engines effectively and stay safe online. This one is also filtered and tested daily by reearchers to make sure it's working as it should. They also have a webpage removal request tool, so that you can report any inappropriate sites that do sneak through. It doesn't have an index like the sites mentioned above, just a search window, so it could be a little harder for kids to use.

Once at the website, of course, students need the skills to know whether or not a website is credible and worth reading. I wonder how many of my learners would be able to pick this website about the Pacific Northwest Tree Octopus as a fake?

Kathy Shrock has some great resources designed to help learners take a closer look at a website and evaluate it.

I particularly like the '5 W's of Web Evaluation' and her Critical Evaluation of a Website sheets that students can fill out to evaluate websites. These tools are great for developing information literacy skills.

Andrew Churches has a good collection of links to some great boolean search tools here.

The internet is a vast space with some wonderful opportunities for learning. Learners can miss out on this if they lack the skills to even get through 'the gate' and efficiently find what they are looking for.
