This week’s topic is building an online classroom.
We discussed this issue in the class this week. How to build an online
community? This question is really hard to answer. Building an online community
is not an easy task. From my perspective, the online community initiated in a course
management system is mostly forced. Learner’s participation in the online community
is not spontaneous if the learner is not interested in it
or forced to involve in this community by course policies or other external factors.
I guess this is the nature and one shortcoming of learning management system
which might be hard to conquer. This makes me to think about the use of virtual
learning environment, such as Second Life. Did anyone use Second Life before? What
about the online community in Second Life? Could it be really different from
the one in course management system? Is the communication in virtual learning environment
more effective than learning management system?
Additionally, I would
like to introduce Richard Mayer’s cognitive theory of multimedia learning. This
theory is based on three main assumptions: there
are two separate channels (auditory and visual) for processing information;
there is limited channel capacity; and that learning is an active process of
filtering, selecting, organizing, and integrating information. The figure below
presents the model of how people learn from multimedia lessons.
The principle known as the “multimedia
principle” states that “people learn more deeply from words and pictures than
from words alone”. However, simply adding words to pictures is not an
effective way to achieve multimedia learning. The goal is to instructional
media in the light of how human mind works. This is the basis for Mayer’s
cognitive theory of multimedia learning.
Mayer’s cognitive theory of multimedia
learning presents the idea that the brain does not interpret a multimedia
presentation of words, pictures, and auditory information in a mutually
exclusive fashion; rather, these elements are selected and organized
dynamically to produce logical mental constructs. Design principles including
providing coherent verbal, pictorial information, guiding the learners to
select relevant words and images, and reducing the load for a single processing
channel etc. can be entailed from this theory.
