Further Information
Instructional television (ITV), is an effective distance education delivery
system that can be integrated into the curriculum at three basic levels:
Single lesson - Programs address one specific topic
or concept, providing a lesson introduction, overview, or summary.
Selected unit - A series of programs providing the content
foundation for a learning unit in the course curriculum.
Full course - Programs from one or more ITV series may
be integrated into a full semester course typically in conjunction with
instructional print materials.
ITV may be either passive or interactive. Passive ITV typically involves
pre-produced programs which are distributed by video cassette or by video-based
technologies such as broadcast, cable, or satellite. In contrast, interactive
ITV provides opportunities for viewer interaction, either with a live
instructor or a participating student site. For example, two-way television
with two-way audio allows all students to view and interact with the teacher
(see Lochte, 1993). At the same time, cameras at remote sites allow the
teacher to view all participating students. It is also possible to configure
the system so that all student sites may view one another.
- Since most people have watched television, the medium is familiar.
- Motion and visuals can be combined in a single format so that complex
or abstract concepts can be illustrated through visual simulation. The
old cliche "a picture is worth a thousand words" rings true.
- Instructional television is an effective way to take students to new
environments (the moon, a foreign country, or through the lens of a
microscope).
- Time and space can be collapsed, so that events can be captured and
relayed as they happen.
- It is very effective for introducing, summarizing, and reviewing concepts.
- It can be used effectively as a motivational tool.
- Broadcast quality ITV is expensive to create.
- Video production is time consuming and can be technically demanding,
often requiring relatively sophisticated production facilities and equipment.
- Sites choosing to interactively participate in an ITV program may
require specialized equipment, facilities, and staffing.
- Most prepackaged ITV courses use a mass media approach to instruction
aimed at the average student. As a result, they can be ineffective in
serving students with special needs.
- When used passively, without interaction, its instructional effectiveness
can be limited.
- Unless professionally produced, completed ITV programs often look
amateurish.
- Once completed, ITV programs can be difficult to revise and update.
In designing instruction for ITV, the challenge is to think in visual terms.
Taking advantage of the visual imagery of ITV can counter an over-reliance
on lecturing. Carefully planning ways to show instead of tell may improve
the instructional effectiveness of ITV. It may be helpful to visually represent:
- Outlines or lists
- Key points
- Complex material in a step-by-step fashion
- Relationships
- Information that needs to be summarized for retention and recall
Make use of:
- Pictures -- to show what things look like.
- Diagrams -- to illustrate conceptual relationships, organizations,
and structure of content material.
- Maps -- to show spatial relationships.
- Graphs, tables, and charts -- to summarize information.
Take advantage of video's ability to show movement to:
- Demonstrate the operation of tools and equipment.
- Demonstrate skills that learners are expected to emulate.
- Conduct experiments in which the processes must be observed.
- Analyze change over time using animation, slow motion, or time lapse
photography.
- Reveal the spatial, three-dimensional qualities of an object or structure.
- Transport learners to places or situations not otherwise in their
experience.
- Present primary source materials for analysis, such as film of historical
events or naturally occurring situations.
Because teachers and students are physically separated by a distance,
the teacher's challenge is to psychologically reduce the gap not only
through the appropriate use of technology but also through the use of
effective teaching practices. Good teaching ensures that a rapport develops
between students and teacher. Once basic teaching methods are considered,
try employing the following three step strategy for conducting ITV lessons:
1. Set the Stage
- Remember that it takes longer to deliver instruction at a distance
than in a traditional face-to-face setting. Plan lessons accordingly.
- Practice in front of a live camera prior to class. If possible, have
a colleague, a few target students, or a media technician view your
presentation and on-camera presence, offering suggestions for improvement.
- Organize all class materials and visuals before the start of the class.
It is best to have a trial run with technical staff so that all participants
know the role they are expected to play.
- If using an overhead camera to electronically project visuals, understand
its operation and limitations prior to the start of the class.
- Prepare viewers for new terminology to be used in the program, and
answer any questions regarding the technical equipment being used, such
as cameras, television monitors, audio equipment, etc..
- Inform students if there will be camera operators or technicians in
the classroom. Although the students may be initially curious, this
will fade as the class progresses. In-class technicians are trained
to be as unobtrusive as possible.
- Students should have the necessary background materials to make the
best use of televised lessons. Consider the use of study questions to
assist in focusing discussions.
- Consider team teaching to maintain viewer interest with a change of
voice, image, and presentation style. If using guest speakers, give
students necessary background information prior to the class. Do the
same for the guest speakers. Let them know the specific purpose of their
session, what is expected of them, and the general background of participating
students.
2. During the ITV Session
- Vary facial expressions, tone of voice, body movements, and eye contact
with the camera to enhance verbal communication.
- Engage students by using humor, asking questions, involving students,
and praising student contributions.
- Maintain energy and dynamism to attract and hold the distant learners'
attention. Remember, enthusiasm is contagious. So is boredom.
- Present content in five to ten minute blocks interspersed with discussion.
Alternate between instruction and interaction.
- Keep lecture sessions simple and clear. To help focus viewing, indicate
key points to look for.
- Do not read material.
- Maintain a moderate speaking pace.
- Do not digress -- keep students on track.
- Include different kinds of student involvement-- watching, reading,
writing, and talking.
- Vary the center of focus for activities from the on-camera presenter
to a receive site group or individual.
- Incorporate timely breaks as a respite from the television monitor.
- Motivate peer learning and support by encouraging students to work
together both in and out of class.
- Review the concepts discussed in the program and clarify any misunderstandings
by asking focused questions.
- Integrate activities to reinforce the content presentation. These
activities might include quizzes, worksheets, role-playing, and experiments.
Make sure opportunities are included to enhance student interaction by:
- Planning a block of time for interaction and then letting students
know in advance that interaction is anticipated. Initiating an interaction
within the first twenty minutes will get students motivated to participate
in learning rather than lulling them into just watching.
- Designating students at distant sites to lead discussions or survey
the room for questions.
- Clearly defining discussion topics or questions and then allowing
time for students to prepare responses. Assigning discussion questions
in advance of the television session will help students prepare for
the interaction. Have the questions appear in writing on the screen
so students see and hear the questions.
- Encouraging student-to-student interaction by asking an in-class student
or a student from a distant site to respond to questions. The instructor
does not always have to answer questions.
- Functioning as content facilitator not just content provider.
3. Following the Session
- Review the taped recordings of the presentation, either with technical
staff, a colleague, or by yourself. Take notes for improving presentation,
style, and delivery methods.
- Seek student feedback on the strengths and weaknesses of the instructional
materials and the teaching strategies being used.
- Be open to new ideas and delivery techniques for improving instructional
effectiveness.
