Distance Education: An Overview
What is Distance Education?
Within a context of rapid technological change and
shifting market conditions, the American education system
is challenged with providing increased educational
opportunities without increased budgets. Many educational
institutions are answering this challenge by developing
distance education programs. At its most basic level,
distance education takes place when a teacher and
student(s) are separated by physical distance, and
technology (i.e., voice, video, data, and print), often
in concert with face-to-face communication, is used to
bridge the instructional gap. These types of programs can
provide adults with a second chance at a college
education, reach those disadvantaged by limited time,
distance or physical disability, and update the knowledge
base of workers at their places of employment.
Is Distance Education
Effective?
Many educators ask if distant students learn as much as
students receiving traditional face-to-face instruction.
Research comparing distance education to traditional
face-to-face instruction indicates that teaching and
studying at a distance can be as effective as traditional
instruction, when the method and technologies used are
appropriate to the instructional tasks, there is
student-to-student interaction, and when there is timely
teacher-to- student feedback (see Moore & Thompson,
1990; Verduin & Clark, 1991).
How is Distance
Education Delivered?
A wide range of technological options are available to
the distance educator. They fall into four major
categories:
Voice - Instructional audio tools include the interactive
technologies of telephone, audioconferencing, and
short-wave radio. Passive (i.e., one-way) audio tools
include tapes and radio.
Video - Instructional video tools include still images
such as slides, pre-produced moving images (e.g., film,
videotape), and real-time moving images combined with
audioconferencing (one-way or two-way video with two-way
audio).
Data - Computers send and receive information
electronically. For this reason, the term
"data" is used to describe this broad category
of instructional tools. Computer applications for
distance education are varied and include:
Computer-assisted instruction (CAI) - uses the computer
as a self-contained teaching machine to present
individual lessons.
Computer-managed instruction (CMI) - uses the computer to
organize instruction and track student records and
progress. The instruction itself need not be delivered
via a computer, although CAI is often combined with CMI.
Computer-mediated education (CME) - describes computer
applications that facilitate the delivery of instruction.
Examples include:
electronic mail, fax, real-time computer conferencing,
and World-Wide Web applications.
Print - is a foundational element of distance education
programs and the basis from which all other delivery
systems have evolved. Various print formats are available
including: textbooks, study guides, workbooks, course
syllabi, and case studies.
Which Technology is Best?
Although technology plays a key role in the delivery of
distance education, educators must remain focused on
instructional outcomes, not the technology of delivery.
The key to effective distance education is focusing on
the needs of the learners, the requirements of the
content, and the constraints faced by the teacher, before
selecting a delivery system. Typically, this systematic
approach will result in a mix of media, each serving a
specific purpose. For example:
A strong print component can provide much of the basic
instructional content in the form of a course text, as
well as readings, the syllabus, and day-to-day schedule.
Interactive audio or video conferencing can provide real
time face-to-face (or voice-to-voice) interaction. This
is also an excellent and cost-effective way to
incorporate guest speakers and content experts.
Computer conferencing or electronic mail can be used to
send messages, assignment feedback, and other targeted
communication to one or more class members. It can also
be used to increase interaction among students.
Pre-recorded video tapes can be used to present class
lectures and visually oriented content.
Fax can be used to distribute assignments, last minute
announcements, to receive student assignments, and to
provide timely feedback.
Using this integrated approach, the educator's task is to
carefully select among the technological options. The
goal is to build a mix of instructional media, meeting
the needs of the learner in a manner that is
instructionally effective and economically prudent.
Effective Distance Education:
Without exception, effective distance education programs
begin with careful planning and a focused understanding
of course requirements and student needs. Appropriate
technology can only be selected once these elements are
understood in detail. There is no mystery to the way
effective distance education programs develop. They don't
happen spontaneously; they evolve through the hard work
and dedicated efforts of many individuals and
organizations. In fact, successful distance education
programs rely on the consistent and integrated efforts of
students, faculty, facilitators, support staff, and
administrators.
Key Players in Distance Education
The following briefly describes the roles of these key
players in the distance education enterprise and the
challenges they face.
Students - Meeting the instructional needs of students is
the cornerstone of every effective distance education
program, and the test by which all efforts in the field
are judged. Regardless of the educational context, the
primary role of the student is to learn. This is a
daunting task under the best of circumstances, requiring
motivation, planning, and an ability to analyze and apply
the instructional content being taught. When instruction
is delivered at a distance, additional challenges result
because students are often separated from others sharing
their backgrounds and interests, have few if any
opportunities to interact with teachers outside of class,
and must rely on technical linkages to bridge the gap
separating class participants.
Faculty - The success of any distance education effort
rests squarely on the shoulders of the faculty. In a
traditional classroom setting, the instructor's
responsibility includes assembling course content and
developing an understanding of student needs. Special
challenges confront those teaching at a distance. For
example, the instructor must:
Develop an understanding of the characteristics and needs
of distant students with little first-hand experience and
limited, if any, face-to-face contact.
Adapt teaching styles taking into consideration the needs
and expectations of multiple, often diverse, audiences.
Develop a working understanding of delivery technology,
while remaining focused on their teaching role.
Function effectively as a skilled facilitator as well as
content provider.
Facilitators - The instructor often finds it beneficial
to rely on a site facilitator to act as a bridge between
the students and the instructor. To be effective, a
facilitator must understand the students being served and
the instructor's expectations. Most importantly, the
facilitator must be willing to follow the directive
established by the teacher. Where budget and logistics
permit, the role of on-site facilitators has increased
even in classes in which they have little, if any,
content expertise. At a minimum, they set up equipment,
collect assignments, proctor tests, and act as the
instructor's on-site eyes and ears.
Support Staff - These individuals are the silent heroes
of the distance education enterprise and ensure that the
myriad details required for program success are dealt
with effectively. Most successful distance education
programs consolidate support service functions to include
student registration, materials duplication and
distribution, textbook ordering, securing of copyright
clearances, facilities scheduling, processing grade
reports, managing technical resources, etc.. Support
personnel are truly the glue that keeps the distance
education effort together and on track.
Administrators - Although administrators are typically
influential in planning an institution's distance
education program, they often lose contact or relinquish
control to technical managers once the program is
operational. Effective distance education administrators
are more than idea people. They are consensus builders,
decision makers, and referees. They work closely with
technical and support service personnel, ensuring that
technological resources are effectively deployed to
further the institution's academic mission. Most
importantly, they maintain an academic focus, realizing
that meeting the instructional needs of distant students
is their ultimate responsibility.
GUIDE 2: Strategies for Teaching at a Distance
What's Different About Distant Teaching?
Classroom teachers rely on a number of visual and
unobtrusive cues from their students to enhance their
delivery of instructional content. A quick glance, for
example, reveals who is attentively taking notes,
pondering a difficult concept, or preparing to make a
comment. The student who is frustrated, confused, tired,
or bored is equally evident. The attentive teacher
consciously and subconsciously receives and analyzes
these visual cues and adjusts the course delivery to meet
the needs of the class during a particular lesson.
In contrast, the distant teacher has few, if any, visual
cues. Those cues that do exist are filtered through
technological devices such as video monitors. It is
difficult to carry on a stimulating teacher-class
discussion when spontaneity is altered by technical
requirements and distance.
Without the use of a real-time visual medium such as
television, the teacher receives no visual information
from the distant sites. The teacher might never really
know, for example, if students are asleep, talking among
themselves or even in the room. Separation by distance
also affects the general rapport of the class. Living in
different communities, geographic regions, or even states
deprives the teacher and students of a common community
link.
Why Teach at a Distance?
Many teachers feel the opportunities offered by distance
education outweigh the obstacles. In fact, instructors
often comment that the focused preparation required by
distance teaching improves their overall teaching and
empathy for their students. The challenges posed by
distance education are countered by opportunities to:
Reach a wider student audience
Meet the needs of students who are unable to attend
on-campus classes
Involve outside speakers who would otherwise be
unavailable
Link students from different social, cultural, economic,
and experiential backgrounds
Improving Planning and Organization
In developing or adapting distance instruction, the core
content remains basically unchanged, although its
presentation requires new strategies and additional
preparation time. Suggestions for planning and organizing
a distance delivered course include:
Begin the course planning process by studying distance
education research findings. There are several research
summaries available (see Moore & Thompson, 1990).
Before developing something new, check and review
existing materials for content and presentation ideas.
Analyze and understand the strengths and weaknesses of
the possible delivery systems available to you (e.g.,
audio, video, data, and print) not only in terms of how
they are delivered (e.g., satellite, microwave, fiber
optic cable, etc..), but in terms of learner needs and
course requirements before selecting a mix of
instructional technology.
Hands-on training with the technology of delivery is
critical for both teacher and students. Consider a
pre-class session in which the class meets informally
using the delivery technology and learns about the roles
and responsibilities of technical support staff.
At the start of class initiate a frank discussion to set
rules, guidelines, and standards. Once procedures have
been established, consistently uphold them.
Make sure each site is properly equipped with functional
and accessible equipment. Provide a toll-free
"hotline" for reporting and rectifying
problems.
If course materials are sent by mail, make sure they are
received well before class begins. To help students keep
materials organized, consider binding the syllabus,
handouts, and other readings prior to distribution.
Start off slowly with a manageable number of sites and
students. The logistical difficulties of distant teaching
increase with each additional site.
Meeting Student Needs
To function effectively, students must quickly become
comfortable with the nature of teaching and learning at a
distance. Efforts should be made to adapt the delivery
system to best motivate and meet the needs of the
students, in terms of both content and preferred learning
styles. Consider the following strategies for meeting
students' needs:
Assist students in becoming both familiar and comfortable
with the delivery technology and prepare them to resolve
the technical problems that will arise. Focus on joint
problem solving, not placing blame for the occasional
technical difficulty.
Make students aware of and comfortable with new patterns
of communication to be used in the course (Holmberg,
1985).
Learn about students' backgrounds and experiences.
Discussing the instructor's background and interests is
equally important.
Be sensitive to different communication styles and varied
cultural backgrounds. Remember, for example, that
students may have different language skills, and that
humor is culturally specific and won't be perceived the
same way by all.
Profile of the Distant Student
The primary role of the student is to learn. Under the
best of circumstances, this challenging task requires
motivation, planning, and the ability to analyze and
apply the information being taught. In a distance
education setting, the process of student learning is
more complex for several reasons (Schuemer, 1993):
Many distance-education students are older, have jobs,
and families. They must coordinate the different areas of
their lives which influence each other their
families, jobs, spare time, and studies.
Distant students have a variety of reasons for taking
courses. Some students are interested in obtaining a
degree to qualify for a better job. Many take courses to
broaden their education and are not really interested in
completing a degree.
In distance education, the learner is usually isolated.
The motivational factors arising from the contact or
competition with other students is absent. The student
also lacks the immediate support of a teacher who is
present and able to motivate and, if necessary, give
attention to actual needs and difficulties that crop up
during study.
Distant students and their teachers often have little in
common in terms of background and day-to-day experiences
and therefore, it takes longer for student-teacher
rapport to develop. Without face-to-face contact distant
students may feel ill at ease with their teacher as an
"individual" and uncomfortable with their
learning situation.
· In distance education settings, technology is
typically the conduit through which information and
communication flow. Until the teacher and students become
comfortable with the technical delivery system,
communication will be inhibited.
Distant Students' Development as Learners
Beginning students may have some difficulty determining
what the demands of a course of academic study actually
are because they do not have the support of an immediate
peer group, ready access to the instructor, or
familiarity with the technology being used for delivery
of the distance-education course. They may be unsure of
themselves and their learning. Morgan (1991) suggests
that distant students who are not confident about their
learning tend to concentrate on memorizing facts and
details in order to complete assignments and write exams.
As a result, they end up with a poor understanding of
course material. He views memorization of facts and
details as a surface approach to learning and
summarizes it as follows:
· Surface approach:
Focus on the "signs" (e.g., the text or
instruction itself).
Focus on discrete elements.
Memorize information and procedures for tests.
Unreflectively associate concepts and facts.
Fail to distinguish principles from evidence, new
information from old.
Treat assignments as something imposed by the instructor.
· External emphasis focusing on the demands of
assignments and exams leading to a knowledge that is
cut-off from everyday reality.
Distant students need to become more selective and
focused in their learning in order to master new
information. The focus of their learning needs to shift
them from a surface approach to a deep
approach. Morgan (1991) summarizes this approach as
follows:
· Deep Approach:
Focus on what is "signified" (e.g., the
instructors arguments).
Relate and distinguish new ideas and previous knowledge.
Relate concepts to everyday experience.
Relate and distinguish evidence and argument.
Organize and structure content.
Internal emphasis focusing on how instructional material
relates to everyday reality.
Improving Distant Learning
The shift from surface to deep
learning is not automatic. Brundage, Keane, and Mackneson
(1993) suggest that adult students and their instructors
must face and overcome a number of challenges before
learning takes place including: becoming and staying
responsible for themselves; "owning" their
strengths, desires, skills, and needs; maintaining and
increasing self-esteem; relating to others; clarifying
what is learned; redefining what legitimate knowledge is;
and dealing with content. These challenges are considered
in relation to distance education:
"Becoming and staying responsible for
themselves". High motivation is required to complete
distant courses because the day-to-day contact with
teachers and other students is typically lacking.
Instructors can help motivate distant students by
providing consistent and timely feedback, encouraging
discussion among students, being well prepared for class,
and by encouraging and reinforcing effective student
study habits.
"Owning ones strengths, desires, skills,
needs". Students need to recognize their strengths
and limitations. They also need to understand their
learning goals and objectives. The instructor can help
distant students to explore their strengths/limitations
and their learning goals/objectives by assuming a
facilitative role in the learning process. Providing
opportunities for students to share their personal
learning goals and objectives for a course helps to make
learning more meaningful and increases motivation.
"Maintaining and increasing self-esteem".
Distant students may be afraid of their ability to do
well in a course. They are balancing many
responsibilities including employment and raising
children. Often their involvement in distance education
is unknown to those they work with and ignored by family
members. Student performance is enhanced if learners set
aside time for their instructional activities and if they
receive family support in their academic endeavors. The
instructor can maintain student self-esteem by providing
timely feedback. It is critical for teachers to respond
to students questions, assignments, and concerns in
a personalized and pleasant manner, using appropriate
technology such as fax, phone, or computer. Informative
comments that elaborate on the individual students
performance and suggest areas for improvement are
especially helpful.
"Relating to others". Students often learn most
effectively when they have the opportunity to interact
with other students. Interaction among students typically
leads to group problem solving. When students are unable
to meet together, appropriate interactive technology such
as E-mail should be provided to encourage small group and
individual communication. Assignments in which students
work together and then report back or present to the
class as a whole, encourage student-to-student
interaction. Ensure clear directions and realistic goals
for group assignments (Burge, 1993).
"Clarifying what is learned". Distant students
need to reflect on what they are learning. They need to
examine the existing knowledge frameworks in their heads
and how these are being added to or changed by incoming
information. Examinations, papers, and class
presentations provide opportunities for student and
teacher to evaluate learning. However, less formal
methods of evaluation will also help the students and
teacher to understand learning. For example, periodically
during the course the instructor can ask students to
write a brief reflection on what they have learned and
then provide an opportunity for them to share their
insights with other class members.
"Redefining what legitimate knowledge is".
Brundage, Keane, and Mackneson (1993) suggest that adult
learners may find it difficult to accept that their own
experience and reflections are legitimate knowledge. If
the instructor takes a facilitative rather than
authoritative role, students will seetheir own
experience as valuable and important to their further
learning. Burge (1993) suggests having learners use
first-person language to help them claim ownership of
personal values, experiences, and insights.
"Dealing with content". Student learning is
enhanced when content is related to examples. Instructors
tend to teach using examples that were used when they
received their training. For distance learning to be
effective, however, instructors must discover examples
that are relevant to their distant students. Encourage
students to find or develop examples that are relevant to
them or their community.
In Conclusion
Teaching and learning at a distance is demanding.
However, learning will be more meaningful and
deeper for distant students, if the students
and their instructor share responsibility for developing
learning goals and objectives; actively interacting with
class members; promoting reflection on experience;
relating new information to examples that make sense to
learners; maintaining self-esteem; and evaluating what is
being learned. This is the challenge and the opportunity
provided by distance education.
Common Research Questions
Because distance education is perceived as an
increasingly effective method of instruction, educational
researchers have examined the purposes and situations for
which distance education is best suited. Frequently asked
questions cluster in five areas:
Is technology-assisted, distant teaching as effective as
traditional face-to-face teaching?
What factors determine the most effective mix of
technology in a given distant teaching situation?
What are the characteristics of effective distant
students and teachers?
How important is teacher-student and student-student
interaction in the distance education process and in what
form(s) can this interaction most effectively take place?
What cost factors should be considered when planning or
implementing distance education programs and how are
those costs offset by benefits to the learner?
Distance vs. Traditional Education
Research indicates that the instructional format itself
(e.g., interactive video vs. videotape vs.
"live" instructor) has little effect on student
achievement as long as the delivery technology is
appropriate to the content being offered and all
participants have access to the same technology. Other
conclusions drawn from this line of research suggest:
Achievement on various tests administered by course
instructors tends to be higher for distant as opposed to
traditional students (Souder, 1993), yet no significant
difference in positive attitudes toward course material
is apparent between distant and traditional education
(Martin & Rainey, 1993).
Conventional instruction is perceived to be better
organized and more clearly presented than distance
education (Egan, et al., 1991).
The organization and reflection needed to effectively
teach at a distance often improves an instructor's
traditional teaching.
Future research should focus on the critical factor in
determining student achievement: the design of
instruction itself (Whittington, 1987).
Why are Students Successful?
Research suggests distant students bring basic
characteristics to their learning experience which
influence their success in coursework. Distance education
students:
Are voluntarily seeking further education.
Have post-secondary
education goals with expectations for higher grades
(Schlosser & Anderson, 1994).
Are highly motivated and
self-disciplined.
Are older.
Studies also conclude
that similar factors determine successful learning
whether the students are distant or traditional. These
factors include:
Willingness to initiate
calls to instructors for assistance.
Possessing a more
serious attitude toward the courses.
Employment in a field
where career advances can be readily "achieved
through academic upgrading in a distance education
environment" (Ross & Powell, 1990).
Previous completion of a
college degree (Bernt & Bugbee, 1993).
Why is Instruction
Successful?
Good distance teaching practices are fundamentally
identical to good traditional teaching practices and
"those factors which influence good instruction may
be generally universal across different environments and
populations." (Wilkes & Burnham, 1991). Because
distance education and its technologies require extensive
planning and preparation, distance educators must
consider the following in order to improve their
effectiveness (Schlosser & Anderson, 1994):
Extensive pre-planning
and formative evaluation is necessary. Teachers cannot
"wing it". Distance learners value instructors
who are well prepared and organized (Egan, et al., 1991).
Learners benefit
significantly from a well-designed syllabus and
presentation outlines (Egan, et al., 1991). Structured
note taking, using tools such as interactive study
guides, and the use of visuals and graphics as part of
the syllabus and presentation outlines contribute to
student understanding of the course. However, these
visuals must be tailored to the characteristics of the
medium and to the characteristics of the students.
Teachers must be
properly trained both in the use of equipment and in
those techniques proven effective in the distance
education environment. Learners get more from the courses
when the instructor seems comfortable with the
technology, maintains eye contact with the camera,
repeats questions, and possesses a sense of humor (Egan,
et al., 1991).
How Important is
Interaction?
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.
Cost vs. Benefits
When establishing a distance education program, one of
the first things considered is the cost of the system.
Several cost components factor into the design of a
distance education system (Threlkeld & Brzoska,
1994):
Technology - hardware
(e.g., videotape players, cameras) and software (e.g.,
computer programs).
Transmission - the
on-going expense of leasing transmission access (e.g.,
T-1, satellite, microwave).
Maintenance - repairing
and updating equipment.
Infrastructure - the
foundational network and telecommunications
infrastructure located at the originating and receiving
campuses.
Production -
technological and personnel support required to develop
and adapt teaching materials.
Support - miscellaneous
expenses needed to ensure the system works successfully
including administrative costs, registration,
advising/counseling, local support costs, facilities, and
overhead costs.
Personnel - to staff all
functions previously described.
Although the costs of
offering distance education courses may be high, there
are high costs associated with offering conventional
courses. Benefits of distance education courses to the
learner include (Ludlow, 1994):
Accessible training to
students in rural areas.
Students may complete
their course of study without suffering the loss of
salary due to relocation.
Students are exposed to
the expertise of the most qualified faculty.
Perhaps the question
institutions must answer is whether it is part of their
mission as educators to offer programs to those who might
not be reached without distance education. The primary
benefit to educational institutions through distance
education may be the increased number of non-traditional
students they are able to attract and serve. Research
also suggests that as programs become more efficient,
program costs should decrease (Ludlow, 1994).
