In July 1998 we launched Internet Detective - an informal but comprehensive online tutorial designed to teach the skills required to critically evaluate the quality of information found on the Internet.
The tutorial includes interactive quizzes, worked examples and practical hint and tips. It can be accessed via the World Wide Web from:
The tutorial has been developed by staff at The Institute for Learning and Research Technology (ILRT) at the University of Bristol. It uses the TONIC-ng software developed at Netskills at the University of Newcastle and is hosted at Netskills. The tutorial was funded by the European Union as part of DESIRE, a project in the Telematics for Research Programme.
Internet Detective aims to alert people to the questionable quality of the information that is freely available over the Internet. After completing the tutorial users will:
Internet Detective can be useful for anyone using information found via the Internet. It is designed for people who have already acquired basic skills needed to use the Internet and who are now able to focus on the information they find.
It is likely to be of particular relevance to those working with Internet information:
It will also be particularly relevant to those using the Internet for academic purposes:
The tutorial may take three to four hours to complete fully. However, users select a login name and may use this to work over a number of sittings - the login will take them directly to the part of the tutorial at which they left off, and will keep a record of their quiz scores.
Internet Detective is available on the WWW and is freely available for anyone to use. (Users will need to access the tutorial using a Web browser that understands frames and accepts cookies).
Users will need to login and remember their username for re-entry at a later date.
Internet Detective is now freely available from the following URL:
So please feel free to "get on the case" :-)
Internet Detective describes itself as an interactive, online tutorial which provides an introduction to the issues of information quality on the Internet and teaches the skills required to evaluate critically the quality of an Internet resource. The tutorial claims that it has been designed with information professionals and librarians in mind and will also be particularly relevant to researchers, teachers and students. A group of fourth year Information Management students at Queen Margaret College thought it might be interesting to apply the criteria introduced by Internet Detective to the site itself, thereby judging it in accordance with its own standards. The following description and evaluation are the products of collated individual assessments and group discussion.
Internet Detective allows the user to complete the tutorial in either a single session or a number of split sessions. It does this by allowing users to register a login name and password. The tutorial records the users progress and saves their position for the next session. Users are reassured that any part of the tutorial can be repeated at any time.
Initially the site seems well presented. The text is clear, the graphics - although a tad bland - are not over-used, and everything seems to be set out in a sensible fashion. To the left side of the screen is a contents/navigation menu showing where the user is located within the site and the various sections one may jump to. During the tutorial, coloured markers appear beside the contents to show user progress.
The main area of each page makes good use of space and the sections of the tutorial (each on a separate page) contain just enough information for the users not to feel they are being force-fed too much at once. There are occasional quizzes at the end of sections which allow users to test their new knowledge. When users give an incorrect answer in response to a quiz question the system provides an explanation. This is a nice touch which helps users learn why they went wrong, instead of where. Be warned however: using Netscape 3 at Queen Margaret College we find that the processing of the answers can take a little time and you may be tempted to hit the Reload button. One might say a little patience is a system requirement although, generally, the rest of the site is up to speed.
Before evaluating the actual content, a note about the use of frames. Under Netscape 3, where the Contents/navigation menu might be better with a separate frame, here it is actually part of the main page and consequently scrolls off the top of the screen when the user reads text further down the page. (One student who tested this using Internet Explorer 4 from his machine at home, however, found this not to be a problem.) This is not a major issue, but raises a question of usability all the same for particular browser users. While this concern relates more to design than content, remedying it would improve the pages.
Content-wise, the tutorial begins with some excellent tips on general site navigation and the nature of URLs. The information is aimed at beginners and would form a useful part of any introduction to the Web class. Bearing this in mind, it is nice to see that the site takes pains not to use jargon. Some knowledge is assumed but, since the users have already loaded their browser software and navigated their way to the site, this is not unreasonable.
Before progressing to the sections on criteria for evaluation, the tutorial introduces the issues of resource types, formats and, among other things, the difference between primary and secondary information. The first short quiz follows, which is very simple if the user has paid attention to the preceding pages.
The second section of the tutorial considers criteria for evaluating web site content. Bearing in mind that the purpose of this site is to introduce criteria for evaluating web sites, Internet Detective certainly matches its own content criteria. The group feels that the site is genuine, well-researched, unbiased. It includes enough references, statements of sources and aims, and we support its claims to be considered valid, although perhaps not exhaustive. Despite a few typographical errors the site is judged as accurate. All the work contained therein seems to be original and the authors freely give their credentials on the welcome page. All the information required in the tutorial is held on a single academic server, going some way to boosting confidence about the credibility of the quality of the tutorial. The group was pleased to see that no area of the site was under construction. There seems to be no missing information at all.
The third tutorial section considers form criteria. This relates to issues of navigation, user support and technology. The group decided that, when compared to the form criteria, Internet Detective falls a little short of the mark. The site offers no single downloadable file for perusal off-line (despite recommending users to search for such a thing). It was also felt that navigation is not to a standard which could be achieved with a little more design flair.
The final section on evaluation criteria introduces process criteria. The group agree that Internet Detective once again meets its own criteria. The site is judged as durable and reliable, its content is unlikely to lose its relevance for a substantial period of time and although the site does not mention when it was last updated, such updates are unnecessary given the nature of its content.
The tutorial ends its list of criteria and proceeds with some worked examples. These examples make perhaps the best use of graphics in the tutorial. The following Try It Out section allows the users to test their new skills. Users are invited to evaluate (by answering questions) an electronic journal, a mailing list and a subject-based web-site. The Quality Controlled Services page points users towards some reliable Internet resources established for the academic community. When the users reach the end of the package they are presented with a congratulations page and told they may now call themselves Internet Detectives.
Despite being let down slightly by lack of design flair (in terms of presentation as mentioned above), the group judges this site as a worthwhile and informative introduction to evaluation criteria for web sites.
