In the Virtual Classroom, lectures are short and few.
With this being the case, where are the students going to get
the information they need in obtaining the learning objective?
The curriculum of an online
course should be designed to cause dialogue among the students.
During online discussions, the participants collect information
and send it to the virtual classroom for comments, critiques
and more discussion. In order to generate this type of information,
students must actively seek out the required material. The
synergy of the discussion is itself a learning tool. With
that in mind, much of the information presented to the class
can come from the participants themselves.
Methods of information dissemination
that can be used in an online environment are listed below.
Ways that each method can be used have been listed, as well
as the benefits and possible drawbacks associated with each
one. Facilitators need to be aware of problems that can arise
as they use these technologies. For example, while the "lecturette" can
be an effective online tool, long lectures are not recommended
as well as exercises that don't require students to comment
on each other's work.
Textbooks:
They are used for the following purposes
- Assign a segment of a chapter to an individual.
- Assign a segment of a chapter to a team.
- Provide discussion questions that require
students to summarize the reading, or ask students to come
up with their own discussion questions.
- Provide discussion questions that require
students to synthesize the material.
- Provide an activity that requires students
to apply the information from the reading.
Benefits:
Drawbacks:
- They can only be distributed by mail
or retailing network.
- They can convey information only by
written language and figures.
- It is impossible to give direct feedback
to or ask questions of the author.
Video
tapes / TV Programs:
Basic concept of the course content subject or resources
for the virtual classroom discussion can be provided through
video. Whole films can be used in online courses in ESL, literature,
any foreign language, creative writing, etc. Students can watch
the film outside of "class" and then discuss/critique
it in the virtual classroom. During online discussions, students
can compare the film to the book, discuss character profiles,
plot, theme, symbolism, historical context, etc.
Benefits:
-
Facilitator can distribute
information such as visual or procedural concepts that
are hard to express in textbooks. For example: in a class
of manufacturing management, a short film showing a real
factory is effective for understanding certain concepts
and for making discussion questions.
-
Supplemental video may
help learners whose basic learning style is not text-based.
-
If all the students
view the same material, discussion questions or projects
can be assigned to generate discussion on the topic and
the information will be presented equally as well as
using a textbook or related articles.
-
If broadcasting through
web, wave or satellite is available, the information
can be distributed asynchronously, and each student can
view the material at his or her convenience.
-
TV broadcasts can be
recorded for later study or review.
Drawbacks:
- Students are required to have a TV
set and/or a VCR.
- Some programs are only available at
certain designated times.
- VCR tapes can only be distributed
by mail or retailing network.
- When distributed via the WWW, video
files are extremely large, require long download times,
and use substantial memory.
Audio
Tapes / Radio Programs:
Basic concept of the course content subject or
resources for virtual classroom discussion can be provided.
Benefits:
- The cost and technical requirements
are less than for video and/or TV.
- Audio files can be downloaded from
the Internet.
- If all the students listen to the
same material, then discussion questions or projects
can be assigned to generate discussion on the topic,
the information will be presented equally as well as
using a textbook or related articles.
- Radio broadcasts can be recorded for
later study.
Drawbacks:
- Audio files lack a visual component.
- Although much smaller than video files,
audio files are quite large and slow to download.
Guest
Speakers:
Guest speakers can be invited to hold either a synchronous chat session with
the class, or post a lecture and be available for 2-3 days to answer questions
from the group.
Benefits:
- Students can learn about what is happening
today in the real world pertaining to the course content
subject.
- The guest speaker is able to bring
outside resources to the course.
Drawbacks:
- It may be difficult to find an appropriate
person to invite as a guest speaker because he/she must
know the basic system and flow of online learning.
- For synchronous chat sessions: (see
drawbacks below)
Interactive
CD-ROMs /
Interactive PC software
Benefits:
- The material can be used in a self-paced
manner.
- As with video, material which is not
easily adapted to text format can still be covered in
the course.
- Programs can contain short tutorials
for specific skills/information that students need to
know, then require them to apply that knowledge in exercises.
- Software can be distributed through
the Internet.
Drawbacks:
Articles
from Web Sites:
Each participant finds outside, related articles on the Internet; reads,
summarizes, and critiques the article. Other participants can choose to access
the article themselves, and/or comment on their classmate's critique. Students
can then comment on other people's comments. A lot of valid information can
come from this activity.
Benefits:
- It allows students to choose what
to focus on and take control of their own learning experience.
- The number of articles and amount
of information which students can access is unlimited.
- It brings outside resources into the
course.
- It provides participants with an extensive
list of summaries of related resources that they can
choose to read, or archive for later use.
- Students are learning and practicing
research skills--searching, summarizing, demonstrating
what has been learned, integrating new information into
already-learned material.
Drawbacks:
- The information at some Web sites
may not be reliable.
Newsgroups:
This includes subscribing to or even just browsing newsgroups on topics related
to course content.
Benefits:
- There is a large quantity of material
generated every day.
- Most newsgroups have excellent archives
of previously posted material.
Drawbacks:
- There is often a high percentage of "noise" (garbage)
to sift through.
Listservs:
These are focused email discussions on topics supplemental to course work.
Benefits:
- Discussion lists exists on virtually
every academic subject and/or related field.
- Discussion provide an exchange of
ideas with people not enrolled in the class who are,
nevertheless, good resources on a given topic.
Drawbacks:
- Extra reading time is required due
to the large number of messages generated by a busy discussion
list.
Interactive
Web Sites:
These include web sites where users can read information updates, view stills
and video, and listen to audio related to their course work. For example,
the ESL Cafe <http://www.eslcafe.com> puts
ESL students in touch with other language learners around the world as well
as offers expert help in grammar and vocabulary and a chance for students
to publish their writing online.
Interactive, Online Writing
Labs (OWLs) , such as the one offered by Purdue University http://owl.english.purdue.edu/owls/introduction.html,
can be resources for students in online ESL classes or undergraduate
English and writing courses. Also, http://www.arcana.com/shannon/reference/writing.html is
a list of Writer's Resources, including online workshops.
Benefits:
- Students have direct contact with
other learners
- Students have direct contact with
a variety of teachers and are exposed to different teaching
styles.
- Students have "real-life" communication
through email and chat with other learners and teachers.
Drawbacks:
- This activity may distract learners
from other study tasks.
Chatting:
These are online discussions
held by two or more participants synchronously.
Benefits:
Drawbacks:
- With more than two people chatting,
it can become confusing for those who cannot follow several
streams of thought at once.
- It is difficult to coordinate a session
where all students can participate (time differences,
inflexible schedules, etc.).
Off-line
Interview:
Students are assigned to interview a professional, expert, or some other
individual who has a meaningful relationship to the material begin discussed,
and then relate the information gained from the interview to the group.
Benefits:
- Students can talk about people already
involved in the field they are studying, and then broaden
their knowledge-base about the subject even more.
Drawbacks:
- Not all the students may have access
to an appropriate interviewee.
