C-Link development
![Page 4: C-Link: a new information search tool](https://reader036.fdocuments.us/reader036/viewer/2022062323/56815f17550346895dcde2c7/html5/thumbnails/4.jpg)
Why bother?• Students are not making the most of their information
searching, especially in the early stages of their courses:o Limited range of sources.o Limited search strategies.o Problems of information overload.
• Present approaches to searching do not typically cultivate skills of critical analysis or enable dialogue.
•NB Need more research in this area!

What can C-Link do?• Builds a map of relationship between 2 concepts (searching
an archived edition of Wikipedia).• You can explore the map within C-Link.
(move around it/ zoom in and out/ go straight to Wikipedia page)
• You can export and save the map into freely available concept mapping software (Cmap)
• You can then modify the map and specify links/add resources.

And we are topical!
![Page 7: C-Link: a new information search tool](https://reader036.fdocuments.us/reader036/viewer/2022062323/56815f17550346895dcde2c7/html5/thumbnails/7.jpg)
Possible advantages• Discover unknown links and possibilities.• Visual map helps to conceptualise relationships. • Helps to understand the relationships between
concepts that we have never seen before and those with which we are familiar.
• Can focus search on relevant areas without reading articles on unknown concepts in detail.

A preliminary test• Experimental trial, consisting of 10 tasks, half of which
were to be completed using C- ‐Link and the other half using the standard built- ‐in search in Wikipedia.
• For each of the tasks, the participants had five minutes to find five concepts that provided interesting connections between pairs of given concepts.
• They were also asked to rate how difficult each task was and how confident they were in their results.

Different ways ofC-Link searching
• A against A.o Can use to explore definitions by identifying related
concepts.
• A against B.o Identify links.o Explore an areao Suggest new avenues.

Using C-Link search in learning and teaching• Offer the facility to staff and students• Use searches as a basis for discussion• Edit the searches with Cmap as exercise or
as basis for class discussion/posting/online dialogue.

Developmentand potential?
• Industrial/commercial development ongoing.
• Need to build user community for education.
• Potential for research?• Need to link to other databases.

And the barrier …• The classic project issue – a very useful
and flexible tool but limited funding for further development and community building.
• Suggestions most welcome!
