Clark asserted that media are "mere vehicles that deliver instruction, but do not influence student achievement," because it is the content of the medium–not the medium itself that influences achievement. His argument seemed persuasive for a moment, but two questions kept coming to my mind: what does Clark mean by "media," and what forms of electronic technology were available to learners in 1983? Clark mentioned television and computers, but certainly there are more instructional media than those two gadgets. Also, I remember the monochrome educational games on DOS of the early 1980s. I do not think that they compare well to the computerized instructional tools of today, nor was the internet available to the masses then.
The use of television and computers in education does not improve instruction, according to Clark. If the instruction does happen to be more effective in those media it is due to more effort having been made in the instructional design of those materials. Well, I think that perhaps some media facilitate better instructional design. Furthermore, some media make it easier for students to acquire information and free up their time to acquire more in less time. For example, I look at the folks in my classes who have their own lap top computers and wireless access to the internet. Owning and using computers does not make them smarter. Neither does it make the information go to their brains better, but my classmates are able to look up subject matter on the web while in class. They able to update wikis and view and download information relevant to the class discussion immediately. I cannot and, therefore, have to wait until class is over to go to a computer elsewhere to do research. My classmates with the lap tops meanwhile are able to move on to further learning opportunities.
I was glad that we had Kozma’s article to respond to and rebuff Clark’s argument that there should be a moratorium on media research. Kozma shared many feelings of mine that arose when I read Clark’s article. One thing that remained unclear to me however, was the definition of "media." While Kozma went on to discuss books, television, computers and "multimedia" which included slides, sound recordings, interactive video and hypermedia, it seems to me that there are many more types of instructional media. What about lectures, field trips, conferences, discussion groups, models, simulations and role playing to name a few examples? Are these not media? They may not all involve the use of electronic gadgets, but they are media that facilitate and enhance the transmission of knowledge. I believe that all information transfer is mediated, and some media are more effective in meeting that end. Certainly, we should continue researching how media influence and affect learning, for to say that media do not influence learning is absurd.
