Integrated Editing
[I preferred IntelWiki] because it gives
me everything in one window.
18
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.
19
Replacing Manual Search
[IntelWiki] eliminated any need for
[additional searches] because,
virtually anything that's needed I
think was provided in the
[recommended resources]
20
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. - P10
