Preference
17Slide18
Integrated Editing
[I preferred IntelWiki] because it gives me everything in one window.
18Slide19
Easier Resource Inspection
The keywords in the tooltip helped me understand which article will be more suitable for geography.[Keyword highlighting] was very helpful; didn't have to read the whole page, or even the paragraph,
only the lines containing the highlighted words.
19Slide20
Replacing Manual Search
[IntelWiki] eliminated any need for [additional searches] because, virtually anything that's needed I think was provided in the [recommended resources]20Slide21
Lack of Trust
I don't usually trust the highlight and these things. I prefer to study by myself. I preferred the [Default interface] because I can get more facts -- I don't really have to base my knowledge on a limited set of resources. It makes me
more elaborate in my research. - P1021Slide22
