In recent years, due to flourishing growth of internet, every protocol
is approaching standardization and scientific applications are becoming
full-grown everyday. Moreover, with the aid of internet educational
resource and multimedia instruments, web-based instruction system
has been enabled to build an internet learning environment which
is different from traditional one.
Teaching on the internet can not only overcome the limit of time
and space, but also let students become more autonomous in their
time and location of learning. Furthermore, all learning activities
can be recorded in Web Logs automatically under the circumstances
of not interfering with students when browsing learning material,
interactive discussion, or team work learning. Because the Web Logs
may also contain huge amount of non-educational meaning informations,
teachers cannot directly use the Web Logs to observe student learning
behaviors and to check learning situations. Many analytical instruments
of Web Logs cannot either enable teachers to see educational meaning
from Web Logs or carry out learning portfolio analysis.
This research is to provide analysis of student Web Logs easily.
Therefore, OLAP, and graphic data analytical techniques are used
to design a visual learning portfolio analysis system. This system
provides teachers to analyze the procedures of learning activities
from different perspectives and graphic methods in order to understand
the participatory extent of students toward learning activities.
Besides, the evidence of students participate in learning activities
will be surfaced, which can help teachers to evaluate the learning
results effectively.
