There are lot of web search options out there, and not a lot of money in school budgets. Given those two tensions, many districts are looking for ways to save money, and find more “free” options. One of the earliest online tools that my district purchased was NetTrekker, a subscription-based web search service that provides reviewed web sites in its search results. Is it worth the money, or is this a cost schools could reasonably cut? Here’s my input from an elementary perspective.
The Setup:
I ran a search on the word “astronomy.” I used the Elementary page from NetTrekkerDI. To compare, I used Google, Yahoo!Kids (a free, kid-friendly site), KidRex (promising a “Safe Search” version of Google), and MelZoo (which gives a screen-shot preview of the page, great for helping kids figure out if the site is for them). I choose them because these are both subjects that I have had problems locating web sources for in the past.
Findings
Astronomy is one of the few topics where a Google-based search returns something besides a Wikipedia page as the top result, in this case Astronomy.com was returned for all but NetTrekker and Yahoo!Kids. NetTrekker has two excellent sources, Ology, and KidsAstronomy.com, but have duplicate entries for the sites going to obscure pages. The first search result takes you to a hangman game on Kids Astronomy, but there is no high-level result for the entry page on the site. Ology, another great resource, has multiple entries. Yahoo!Kids had a similar random quality to it.
Search results
· astronomy - Google Search
· Yahoo! Kids : Search Results
· MelZoo - Web results for “astronomy”
· astronomy - KidRex
· This is a link to bookmarks for the first page of the results returned from my NetTrekker search, the number indicates the order it appeared in the results.
I got much better results from Google-based search engines (Google and MelZoo) when I added the term “children” to “astronomy”. KidRex appeared to already do this.
The verdict
You don’t always get what you pay for. Much of the elementary content you get for a fee from NetTrekker, you can find elsewhere for free simply by adding the term “children” to your search. There are other bells and whistles on NetTrekker, but some of them (the text to speech function) don’t work well with low-memory computers, such as the ones in my lab. I think the visual previews (from free services like MelZoo) are more useful.
I’ve supported using NetTrekker as one among many tools for students, but even then I noted it’s limitations in not being as up-to-the-minute on all subjects. In addition, kids need to have a broad-based curriculum in using search engines, which includes:
- using Boolean operators (AND, OR, “-”)
- evaluating search result entries before going to the page
- evaluating search result entries after going to the page
NetTrekker attempts to make most of those lessons unnecessary. This is not a good thing for kids because they will be using Google, or similar tools, outside the classroom. -ALICE MERCER
