| dc.description.abstract | Students usually turn to on-line information when they
study. Thus they can make up for the infertility of the
textbook contents, solving their questions and acquiring
more complete knowledge. However, sometimes students can
not find satisfying solution on the web, then except for
asking somebody in real-life, they can also post a
question on the forum and discuss with others in the forum
to come up with a proper answer.
However, because the forum is independent from the
textbook, discussions that aimed at some particular
concepts in the textbook is scattered all over the whole
forum. Even if students use keywords to search, they
always find other matterless discussions and have to spend
much time picking up useful discussion-threads they really
interested in. Moreover, when students post new questions,
they must frequently go back to the threads to check if
someone has answered their questions. And, when they need
to keep discussing with others in some threads, each time
they should search out the threads in the forum before
that.
Tracing the progression of discussion threads waste
much time and effort, inducing students’ unwillingness to
ask questions and discuss in an on-line forum. Hence we
propose a framework to combine Q&A management mechanism
with the textbook content. In such way, students can
easily find related discussions in the forum when they
read textbook, and they can subscribe interested threads
and monitor the status and progression of the threads.
These information help students to decide which thread is
worth reading in current context.
