A pedagogical technique is a manner of accomplishing teaching
objectives. The techniques introduced here are organized according
to the four communication paradigms used in computer-mediated
communication. The foregoing considerations result in a framework
of four methods and a number of techniques as shown in figure
3. First, the techniques classified as one-online are characterized
by retrieval of information from online resources and the fact
that a student can perform the learning task without communication
with the teacher or other students (e.g. search of online databases).
Second, the techniques classified as one-to-one can be conducted
via e-mail applications (e.g. e-mail based correspondence studies).
Third, the techniques discussed as one-to-many will typically
be conducted via World Wide Web, bulletin boards or distribution
lists for e-mail (e.g. publication of a lecture). Finally, the
techniques presented as many-to-many can be organized within computer
conferencing systems, bulletin board systems, or distribution
lists for e-mail (e.g. debates).
Verner (1964, 37) referred to "various mechanical instruments, audio-visual aids, physical arrangements, and materials" as devices that can enhance the effectiveness of an adult education process. Verner stated, however, that television could be regarded as a device when used in a classroom and as a method when it is the primary medium used in a distance education setting. From this, one may argue that CMC could be regarded as both device and method. In this study, however, CMC is viewed from the device perspective.
Using the CMC-classification derived from Rapaport (1991), there are four major CMC-devices: information retrieval systems, electronic mail systems, bulletin board systems, and computer conferencing systems. These four CMC-devices correspond primary to the four methods: one-online, one-to-one, one-to-many, and many-to-many.
Building on these foundations, the framework established for the CMC-based teaching system is illustrated in table 4.
