The media debate

Definition

The great "media debate" has been started by Richard Clark and Robert Kozma in the early nineties. The questions is

Clark argues that it is the underlying instructional methods that shape the learning process (not the medium) and that similar learning outcomes can be achieved through the use of difference media. {{According to Clark (1994) there is strong evidence that many, very different types of learning materials or learning activities accomplish the same learning goal. He claims that it is the instruction method that influences learning and that each instruction method could be designed into various types of learning materials or learning activities. In this view choices about learning materials or activities in education should be made for 1. the less expensive (for the University) and 2. the most cognitive efficient (for the students) ways to represent and deliver instruction (Clark, 1994).

== Kozma's arguments

Do media influence learning? Perhaps it is time to rephrase the question: How, do media affect learning? Perhaps it is time to go beyond our concern with "proving" that media "cause" learning so that we can begin to explore the question in more complex ways. Perhaps we should ask, what are the actual and potential relationships between media and learning? Can we describe and understand those relationships? And can we create a strong and compelling influence of media on learning through improved theories, research, and instructional designs? (Kozma, 1994).

Kozma's argument is that certain media “possess particular characteristics that make them both more and less suitable for the accomplishment of certain kinds of learning tasks.” (Kozma, 1994) and he refers to Salomon who argued that “media can be analyzed in terms of their "cognitively relevant" capabilities - i.e., in terms of those characteristics that affect the ways in which individuals represent and process information.”.

These capabilities relate to three aspects of each medium:

1. Technology: the physical, mechanical, or electronic capabilities that determine a medium's function.
2. Symbol system(s): sets of symbolic expressions by which information is communicated according to specific rules and conventions: spoken language, printed text, pictures, numbers, graphs, and musical scores exemplify symbol systems.
3. processing capabilities: a medium's abilities to operate on symbol systems in specified ways-for example, by displaying, receiving, storing, retrieving, organizing, transforming, or evaluating whatever information is available through a particular symbol system.

Each medium can be defined by a set of attributes that define its function, in particular how it allows representations and how it supports the learner to construct and to operate on mental representations. In other words, the assumption is that learning with media is a complementary process within which a learner and a medium interact to expand or refine the learner's mental model of a particular phenomenon.

Therefore Kozma (1994) concludes “If we move from "Do media influence learning?" to "In what ways can we use the capabilities of media to influence learning for particular students, tasks, and situations?" we will both advance the development of our field and contribute to the improvement of teaching and learning.”

The debate goes on

DSchneider believes that:

• Media do have different affordances and therefore media do belong to instructional method, e.g. are part of a pedagogic strategy.
• However, we would agree with Clark that most instructional design models could be implemented with a variety of media.

We believe that technology (including media) is not innocent and that the choice of tools does have a deep impact on teaching and learning. This does not really counter Clark's arguments of course, because he insists that tools must be chosen carefully
