Synchronous Distance Education Support
Systems, Why Does USF Need One?
Shauna Schullo, University of South Florida, 2003
In
1996, McIsaac and Gunawardena stated “distance education, structured
learning in which the student and instructor are separated by time and
place, is currently the fastest growing form of domestic and international
education. What was once considered a special form of education using
nontraditional delivery systems, is now becoming an important concept in
mainstream education.” Due to the advances in technology, distance education
is growing at an even faster rate. However, many educational researchers
discuss the fact that lack of interaction has long been and still is a
drawback of distance learning courses (McIsaac & Gunawardena, 1996; McNabb,
1994; Milbank, 1994;
Sherry, 1996).
Until recently, reliable technology has not been widely available to
alleviate this problem.
Research in distance learning continues to emphasize the importance of
interaction for effective teaching (Anderson, 1995; Fuller & Zhang, 1993;
Garrison, 2001; Hillman, 1994 & 1999; McIsaac, 1999; Moore, 1989; Moore &
Kearsley, 1996; Sherry, 1998; Thomerson, 1996; Vrasidas, 1999; Wagner,
1994). However, most distance education methods, even real time solutions
such as two-way video and audio, try to emulate lecture hall models of
instruction. These methods suffer from long standing pedagogical problems,
namely the lack of active student participation and effective interaction.
To assuage these problems, many instructors are adding asynchronous computer
communications (CMC) to traditional distance learning technologies (McIsaac
& Gunawardena, 1996; Burge & Howard, 1990).
At USF and many other
institutions, the largest majority of distance courses now use online
asynchronous tools, possibly in conjunction with streaming video or other
media enhancements. However, interaction between students and instructors
is still not sufficient to alleviate the isolation and often frustrations
distance students experience. Research shows that this isolation can be a
serious detriment to learning in many cases (Besser & Donahue, 1996;
Cookson, 1989;
Galusha, 1997; Hara & Khling 1999;
Kahl & Cropley, 1986;
Kubala, 1998; Lever-Duffy, et. al., 1996;
Lockett, 1998;
Soles & Moller, 2001;
Twigg, 1997)
Studies indicate that interactions between students and instructors as well
as student-to-student interaction greatly enhance education at a distance by
improving attitudes, encouraging earlier completion of coursework, better
performance on tests, and greater retention (Willis, 1995; Moore, 1989;
Hillman, 1994 & 1999; Harasim, 1990).
A
discussion of some important distance education research on the subject of
interaction was written by Dr. Barry Willis (1995) (http://www.uidaho.edu/eo/distglan.html).
Willis reports,
“Many distant learners require support and
guidance to make the most of their distance learning experiences (Threlkeld
& Brzoska, 1994). This support typically takes the form of some combination
of student-instructor and student-student interaction. Research findings on
the need for interaction have produced some important guidelines for
instructors organizing courses for distant students:
·
Learners
value timely feedback regarding course assignments, exams, and projects
(Egan, et al., 1991).
·
Learners
benefit significantly from their involvement in small learning groups. These
groups provide support and encouragement along with extra feedback on course
assignments. Most importantly, the groups foster the feeling that if help is
needed it is readily available.
·
Learners
are more motivated if they are in frequent contact with the instructor. More
structured contact might be utilized as a motivational tool (Coldeway, et
al., 1980).
·
Utilization of on-site facilitators who develop a personal rapport with
students and who are familiar with equipment and other course materials
increases student satisfaction with courses (Burge & Howard, 1990).
·
The use of
technologies such as fax machines, computers, and telephones can also
provide learner support and interaction opportunities.”
Historically, technologies that increase interaction have been expensive,
difficult to use and not often utilized. With the advances of technology
and the highly prolific use of the Internet, distance learning is changing.
It is now feasible to incorporate interactive instruction using a new model
of distributed learning that combines asynchronous online learning with
online synchronous solutions.
USF
has taken substantial strides to create learning communities that
incorporate many of the above-mentioned interactions and significant
progress has been made in our asynchronous online instructional
environments. However, we still need a solution that adds the synchronous
interaction many students require to complete their learning experience. A
model, which combines both asynchronous and synchronous learning to connect
students, instructors, and educational content in rich, online learning
communities, is our next logical step. The desired outcome of using these
synchronous communication tools is to add value of interaction over "mere"
content. This will enable social-constructionist and collaborative
approaches to learning, provide access to a sense of community that is not
currently available to distance students, and integrate communication into
the structure of courses resulting in students actively able to negotiate
communication situations and increased technology literacy.
One
model suggested by Rensselaer Polytechnic Institute is labeled the 80/20
model (Danchak, 1999). In their model, approximately 80% of a student's
time is spent on self-paced engagement of online materials and about 20% in
interactive, synchronous learning sessions with the instructor and other
students. The percentages given are of course flexible, and should be
adjusted to meet optimal allocations of time between synchronous and
asynchronous components. This ratio is a function of several variables
including the nature of the course content, the age of the students,
development costs, and faculty. Rensselaer facilitates their program with
Learnlinc, an online synchronous courseware solution. Other universities
have chosen different solutions. The current market provides USF with many
options to choose from for our online synchronous classroom and
web-conferencing needs. This paper will outline some of those systems and
will be used to inform the selection process to determine the best solution
for the USF environment.
What follows is a list of advantages and disadvantages to moving into the
synchronous arena flowed by a description of desired product features.
Advantages
To
start the discussion of advantages to online synchronous learning, let's
take a look at the writings of Dr. Betty Collis of
University of Twente
(1996), she
states that there are "four equally compelling advantages to synchronous
systems:
·
Motivation -
synchronous systems focus the energy of the group, providing motivation to
distance learners to keep up with their peers and continue with their
studies.
·
Telepresence
- real time interaction with its opportunity to convey tone and nuance helps
to develop group cohesion and the sense of being part of a learning
community.
·
Good
feedback -
synchronous systems provide quick feedback on ideas and support consensus
and decision-making in group activities, both of which enliven distance
education.
·
Pacing
- synchronous events encourage students to keep up-to-date with the course
and provide a discipline to learning, which helps people to prioritize their
studies. "
In this sense, online
synchronous learning has many similarities to the physical classroom. The
similarities can be a positive element if the best environment is
encouraged. For example, live instruction with immediate feedback and human
touch benefits, interaction with other professionals whose interests are
similar to your own and hands-on labs or exercises with instructor guidance
can motivate and increase student learning. Since a live instructor can lead
synchronous online learning, the same instructional design methodology can
usually be utilized.
When compared to
asynchronous online distance learning, synchronous online learning can be
more effective in many ways. Aside from the irreplaceable value of
interactivity already discussed, the content can be shaped to the needs of a
student, instead of being one-size-fits-all. An instructor can assess
students’ level of knowledge and tailor the course material appropriately.
In addition the inclusion of a scheduled time adds the perception (or
reality) that the instructor a students classmates are pushing them to show
up, providing external motivation, which leads to higher retention and
completion rates.
In
higher education as well as Industry, the trend for distance instruction is
a blended approach, which combines synchronous and asynchronous media in an
attempt to capitalize on the evident benefits of both modes.
Disadvantages
Of
course, synchronous online learning is not for everyone. We will face
certain challenges in implementing and supporting a new approach, especially
since it also includes technology. For starters, users, both instructors and
students, will need to be comfortable with the technology and environment
and able to grasp the concept of this form of online interaction. The loss
of the face-to-face interaction found in a traditional classroom is still a
problem. For some learners this may be irreplaceable, as they understand
concepts better through direct exchange with an instructor. However,
providers of this technology are already making advances to compensate,
acclimating more interactivity and expression of emotions with the ability
to raise your hand, clap or laugh. While this doesn’t put users face-to-face
with their instructor and peers, they do feel more connected. The use of
video (one-way and two-way) would help to alleviate this a bit more, but use
of video increases the barriers of bandwidth limitations.
In
addition, since synchronous online learning is instructor or facilitator
led, inconvenience of scheduling and real time participation will be
drawbacks for some distance learners. Students and instructors will have to
be somewhere they can participate in the course at a specific time. This
place can be anywhere with a decent Internet connection, as most systems
claim to do well at 56K modem speed. Even with the listed disadvantages,
used as a supplement and not as a fulltime replacement for either
face-to-face or asynchronous learning, this method will add value to our
teaching and learning models. |

Synchronous Distance Education Support
Systems Available
The
following is a fairly comprehensive list of products available on the market.
They vary greatly and we did not do extensive testing on all of them.
However, the list is included to make the evaluation complete. Those not
evaluated were removed from the list for one or more of the following reasons:
-
Cost
prohibitive
-
Did not support the structure
needed for our situation (Unix Severs, Windows and PC clients)
-
Missing
significant number of desired features
The remainder of this
paper will provide information on the two systems that seem to meet our needs.
Another system (Web-4M) has become a possibility and may need to be pilot
tested. Both vClass and Horizonlive meet the majority of the desired
requirements for a product of this nature on our campus. Centra was also
tested, the product was good, but it is not feasible as it does not run on
Unix servers and has no Macintosh clients. The following comments will assist
you in understanding how the products performed in a true pilot test situation
with students in a live class. To assist in understanding the following
tables, please refer to this legend:

Need for additional
software/plugins |
Ideally, there would
be no downloads required. However, this is probably not possible. So,
this section will rate how easy it is to install whatever is required
from both the participant side and the instructor/leader side. |
Sun Microsystems Java Web Start or an open-source alternative
(Open-JNLP) must be installed and configured prior to running vClass™
for either a live or a pre-recorded session. This can be a significant
download on a modem, but it is easy to install. |
Simple wizard is run
to check for system compatibilities. Instructions are provided on how
to fix any problems in setup that are found. Possible downloads, but
easy to install and most are small. |

|
Screen Navigation |
Navigation of the
screen can be difficult for users with little to no experience. It is
possible to change the way the windows are structured, and there are
many different elements that need to be navigated. For instance, to
talk, the student will need to know how to activate the microphone
option which is similar to pressing the talk button on a CB radio.

Screen Busyness |
As noted before,
there is a lot on the screen in a SWBCS. This can cause a visual

Instructor ease of
use |
If it is not easy to
use, instructors will not be successful. This category discusses how
easy the systems are to operate from the instructors perspective. Task
such as putting up presentation slides, operating instructor controls
and multitasking in the environment are considered. In addition, the
ability to get help from the system and the intuitive nature of the
system are considered. |
It took me
approximately 1 hour to orient myself to the vClass system the first
time I used it as an instructor. The tools were laid out well and I was
comfortable with the interface fairly quickly.

The first time I used
HorizonLive, it was with no direction from the support people at the
company. I muddled through with the basics, but was unable to
successful use the system to its potential. I will be receiving an hour
of training from HL for the second go around and will see if it helps to
make the experience better. After the training, I was a bit better
equipped, but the operation from an instructor’s perspective was still
not seamless. I still am unable to accomplish everything I know the
system is capable of.

Student ease of use |
Adding considerable
cognitive load to the students by making it difficult to navigate and
use the system will not make for successful use of the synchronous
classroom software. This category discusses how easy the systems are to
operate from the students perspective. Tasks such as viewing
presentation slides, asking for help, using the communication tools and
overall screen usability are discussed. In addition, the ability to get
help from the system and the intuitive nature of the system are
considered. |

Speed/ flexibility,
Quality of transmissions |
In order to
effectively present material to students in different areas with
different technical capabilities, it is important that the system have
some flexibility in how much data is sent at one time. Clear
transmissions at any speed are important. However, we also would like to
not limit ourselves so that we can take advantage of our high bandwidth
capabilities at USF. |

I am not sure that
our tests truly measured this. We would need to add more students (a
large load) to see if there were problems. Although I tested with
students on modems, there was not application sharing and audio tended
to be a slight bit choppy. |

Additional Comments |
|
VClass seems to have
some problems with XP, but this has not been reproduced. However, on my
home machine, I have been unsuccessful in running the program and it
tends to shut down my machine. This may have been fixed in newer
versions, as I have not tried it since Fall semester. Many of the new
features have not been tested in a live session with myself as
instructor and students. Since the initial testing they have improved
the interaction capabilities, added breakout rooms and enhanced their
application sharing to name a few noticeable changes. |
Horizonlive repeated
had problems during the trials I attempted. They did not have support
on the weekends or after hours, so the problems could not be solved.
Initially the testing was as a courtesy, so this did not bother me as
much. However, the last test cost $500. I would consider 2/3 of the
sessions unsuccessful due errors. During one session, the audio console
did not work. The error message was erroneous, leaving me with no idea
what the problem might actually be. On a second instance, the
instructors console became flaky and did not show the students view of
the screen or list participants as they entered. This occurred again in
the last session. This causes many of the tools to be useless (hand-raising)
yes, no, etc.) Polling is an external product and I did not find it
satisfactory. I also was unable to test Breakout rooms as I had only
one channel available. |

Screen Navigation |
Navigation of the
screen can be difficult for users with little to no experience. It is
possible to change the way the windows are structured, and there are many
different elements that need to be navigatged. For instance, to talk, the
student will need to know how to activate the microphone option which is
similar to pressing the talk button on a CB radio. Screen naviigation in
