Internet Courses for Off-Campus Students
In recent years there has been a major transition away from
the traditional lecture-only
environment in many disciplines. Many forces are driving this
change, including availability
of instructional technology, increased emphasis on critical-thinking
skills, increased
amounts of information to be mastered in a limited time and student
demands for more
technology-based instruction.
Another driving force in this movement toward technology-based
instruction is the
growing difficulty of getting all students into the same classroom
at the same time. The
difficulty comes about in part because clinical experiences are
more geographically
dispersed than before and because the average student starting
a professional program
today is much older and has more off-campus responsibilities than
a typical student had
10 or 20 years ago.
An additional force in this transition is the inherent capability
of technology-expanded
instruction to allow students to better master material. This
includes allowing students to
review course-related materials at their own pace, exposing students
to augmented
learning experiences that go beyond the classroom and textbook
plus improving critical
activities through nonlinear exposure to information and additional
activities designed to
encourage critical thinking.
Although there is a wide range of technological options to
supplement classroom
instruction, Internet-based courseware is one that shows great
promise because it allows
student access independent of time or location and permits directed
access to all other
information on the Internet.
WebCT
There are a number of Internet courseware programs such as
Blackboard, Director,
PowerPoint, TenCore, ToolBook II, CBT Express, CourseWorks, Authorware,
Everest,
LearningSpace and Web Course in a Box. The focus of this article
is WebCT, the
software standard used by the University System of Georgia. This
is not a comparison of
available courseware tools but rather a discussion of how Internet
features are used in
courses.
WebCT is a set of tools used to create sophisticated World
Wide Web-based educational
environments. WebCT can be used to deliver online courses or simply
publish materials
as class supplements. Examples of tools in WebCT are chat rooms,
student progress
tracking, group projects, self-evaluations, grade books, autocorrecting
quizzes, e-mail,
automatic index generations, calendars, student homepages and
content searches. It can
run on either a Unix or WindowsNT server and can be used by an
Internet browser such
as Netscape or Explorer.
Features
Lecture Notes
Any document that has been typed on a computer can become part
of a WebCT course.
To accomplish this, the document must be saved in the HTML format
used by the Internet.
Almost all programs have this format option. WebCT then "uploads"
the document from
the instructor's computer to the course system and it becomes
available to students on
the Internet.
One feature of lecture notes on Web CT is document paths. This
creates an indented
outline of all notes and documents and how they relate to each
other. It is useful to break
large documents into several smaller ones so there will be an
extensive outline available
to the students. Students can switch from notes to background
documents, graphics or
Internet sites by use of hypertext (text that, when clicked on,
takes the user to another
screen) inside the document. Creating hypertext is a very simple
task using a Web
browser such as Netscape. Examples of documents that can be used
are lecture notes,
schedules, syllabi, position papers, "deep" or background
information, article reprints,
tables, suggestions on how best to use WebCT materials, etc.
Calendar
As a general rule, students find having a schedule of events
and assignments useful as
they proceed through a course. The calendar feature gives a month-at-a-glance
format,
but any day can be clicked on and the items for that day are listed.
When a student first
enters the calendar area, any new items automatically pop up in
a separate window,
alerting the student to changes or additions. The instructor can
declare any item as
"private" so students cannot see it until it is made
public. This allows the faculty to create
and upload documents or events listings but withhold them from
view until the appropriate
time.
PowerPoint
PowerPoint is a program that allows users to create high-quality
presentations that can
be easily incorporated into WebCT. PowerPoint presentations can
be saved as HTML
and uploaded into WebCT. This allows students to view and print
the actual presentation,
including backgrounds, animations, graphics and notes. If lecture
notes are in a
PowerPoint format (or even in a text-document format), students
can preview notes prior
to class and therefore not be totally consumed by notetaking during
class. This aids in the
learning process as the experience is both visual and auditory
and allows more time to
process information and ask formative questions.
Graphics
Most students are aided significantly by graphics, pictures,
charts and the like because
multiple inputs are more useful than a single source. Adding these
sources to WebCT is
relatively easy. Any graphic saved as either a GIF or JPEG format
(the "style" in which the
images are saved) can be uploaded into the program. These graphics
can be used to
supplement notes, as part of a test or as illustrations used in
assignments.
Internet Sites
The Internet has a wealth of information but unfortunately
is also a source of
misinformation. One of the problems students have with using the
Internet is telling the
difference between valid information and opinion or misinformation.
By having the faculty
select the sites to which the course is linked, students can be
limited to only sites that
have useful information or sites with misinformation. The misinformation
can be used in
exercises to help students develop critical-thinking and analysis
skills. Information sites
are a major supplement to the course content as there are numerous
discussions on
almost any aspect of the profession with differing approaches
and viewpoints. Exposing
students to these alternate approaches helps them better process
the information. Some
sites can be used as laboratories, as they have experiments that
can be conducted over
the Internet. Other sites have a multitude of radiographic images
with and without
notations and pathologies. Both of these site types are very beneficial
to students.
Chat Rooms
One of the deficiencies of any type of distance learning is
the lack of student interaction.
WebCT includes chat rooms (areas where everyone can see what is
being typed by
everyone else at the same time) as part of every course and also
general chat rooms
available to anyone using WebCT. These chat rooms allow for both
formal and informal
student/faculty discussions. An example of a formal interaction
is that in some courses a
portion of the lecture time takes place in the chat room and all
students are required to be
online at that time. This allows students in multiple geographic
areas to participate in
discussions about the course material. Individual students or
small groups of students
also can set up chat discussions on an informal basis. In both
of these situations, WebCT
allows the faculty to see a transcript of all chat room discussions.
Edited small group
discussions can be posted to the entire class if the faculty believes
that would be useful.
When a student enrolls in a course, e-mail service for use
only within that course is
created automatically. The advantage of e-mail is that messages
can be private, so faculty
members can conduct counseling or converse with individual students
in the course
without any other students seeing the exchanges.
Bulletin Board
An electronic bulletin board is very similar to a physical
bulletin board in that it is a public
place to post information. The bulletin board can be used by faculty
to post assignments,
inform students about changes in schedules, remind students of
activities and answer
questions that all students need to know. Use of the bulletin
board also provides
opportunities for class discussions free of time restrictions.
Students who are not able to
be online at a specific time still can ask questions and respond
to discussions that may
take place over several days. This also allows time for students
to reflect on the course
content and consider their responses before posting them.
Student Uploads/Presentations
A valuable activity for any course is the use of presentations
as an assignment.
Presentations help students process course information, develop
critical-thinking skills
and hone communication skills. Unfortunately, most undergraduate
programs include few
of these activities because of classroom time constraints. With
an Internet-based
supplement, students can be required to produce 1 or more presentations
for every
course. These presentations can be in any format the student chooses,
such as
PowerPoint, graphics, video, documents, poster presentations,
etc. All students can be
required to view the presentations and the faculty can track which
students have logged
on to view these items. In this way, the entire class will benefit
from the presentations and
can, if desired, evaluate them.
Testing
WebCT has a testing feature that allows for multiple-choice,
matching and short-answer
questions. As noted earlier, graphics and videos can be incorporated
into tests. There are
2 major drawbacks with the testing feature. One is the amount
of time necessary to load
any multiple-choice test. Unfortunately, it is not possible to
upload an existing test without
extensive modifications in the document or typing the entire test
anew in the appropriate
boxes inside WebCT.
Another issue is test security. Students can print anything
they see on the screen and can
make copies. No Internet courseware on the market has totally
resolved this issue.
Another security issue involves using books and notes while taking
the test. One way to
minimize this problem is to limit the amount of time students
are allowed online to take the
test. This issue should be considered when designing an Internet-based
course.
Support
Learning any new software package can be a daunting task even
in the best of situations.
Fortunately, even in environments where there is no institutional
support for implementing
Internet-based courses, there is a significant amount of online
help. In fact, with WebCT
there is an extensive support system. The first level of help
is the help files online in the
program itself and the example files. These files assist faculty
with learning the numerous
features of the program. To help with the more subtle or obscure
features, there are a
number of development sites on the Internet. One such site is
http://homebrewl.cs.ubc.ca/webct/docs.
With any software package, there are times when something does
not work or does not
work in the way the faculty intended. There are sites to help
troubleshoot problems by
allowing other users to help. An example of this type of site
is http://webct.uga.edu/
hostsys/faculty/developing.html. Yet another type of Internet
assistance is a listserver (bulk
e-mail distribution system) to help share ideas among users. An
example of this type of
listserver is webct-users@cs.ubc.ca.
Case Example
There is a major effort to develop Internet-based courses at
Armstrong Atlantic State
University. The Department of Radiologic Sciences has partially
or totally placed 7
courses on WebCT. These course offerings range from supplemental
classroom
activities to courses taught totally with WebCT for off-campus
students. One example of
supplementing a course is "Radiobiology and Protection."
In this course all lecture notes,
PowerPoint presentations, schedules and background articles are
posted to aid students.
Several Internet sites with additional information or different
approaches to the same
information are linked. Examples of some of the linked sites are
radiation accidents,
human radiation experiments, cell biology and chromosomal sites,
lists of advisory
bodies, dosimetry sites, health effects of radiation sites, history
sites, physics and
protection publication sites and research sites.
Some students take courses without ever setting foot in a classroom
on campus. One
option for these off-campus students is courses that are totally
WebCT based. An
example of this type of course is "Fundamentals of Radiation
Therapy." In addition to the
syllabus and class notes, there are such useful things as a section
on The Seven Habits
of Highly Effective People, online tests, therapeutic communication
skills, step-by-step
simulation tutorials, information on state licensure, links dealing
with payment issues and
CPT codes, breast cancer risk sites, dose calculation sites, a
virtual simulation site and
journal sites. This gives the online student an array of activities
in addition to the course
textbook and lecture notes.
The Department of Radiologic Science (www.radsci. armstrong.edu)
currently is in the
process of placing all courses necessary to complete the R.T.
to B.S.R.T. program online
using WebCT. This will allow any technologist or therapist with
an associate's degree or
certificate to complete his or her baccalaureate degree from their
home computer.
The program will include all of the advanced professional courses
in addition to links and
agreements with sites offering general education courses such
as English or history. The
goal of this R.T. to B.S.R.T. program is that the average student
will never have to travel to
any campus unless he or she wants to. Although there are several
issues yet to be
resolved before this option can be offered publicly, the reality
of Internet-based degrees in
radiologic sciences is close at hand.
