14 – Assessment and Evaluation
An undocumented (though discussed
on the WebCT listserv)
variable in WebCT is the
_COURSEID_ variable. This variable
takes on the value of the
course root name; you can use it to
locate the path to the image.
The value of using this variable is that it enables you to
easily transfer a database of questions from you WebCT
module to another, as long as the directory structure is
logically the same. It also allows you to zip your course
into a different WebCT root name.
Even though I am using the multiple choice question
as an example, these methods of linking to files to provide
content for a quiz apply to all the question types.
The WebCT quiz environment is quite versatile and
rich. Beyond the scope of this article, there are many
other options that can be set at the individual question
level, such as randomization of the index, multiple
choice questions can be configured to accept only one
answer or a number of possible answers each with a
different value, etc. In addition, the quiz module itself,
as distinct from the questions in the quiz, has a variety
of different settings, which allows the quiz to be managed
in a variety of different ways. In the section on supervising
quizzes, I will discuss in some detail the quiz
module settings.
In summary then, from within WebCT questions, there
are two easy ways to link to images for display during a
quiz, you is using the IMAGE FIELD in the question
section and another is using the tag
within the question field, the answer # field, the feedback
# field, and the general feedback field.
USING JAVASCRIPT TO LINK TO FILES
Besides using HTML tags in the
fields of a question, you can also
use JavaScript to link to images,
and this gives you the ability to
create pop-up windows in your
quizzes.
