An experiment in inservice training for language teachers is described. The experiment consists of using radio, television, written materials, or tapes to introduce topics in applied linguistics that are relevant to second language teaching methods. The object of the experiment is to determine whether this method, in which the instructor and the instructed do not interact face-to-face, is as effective as classroom instruction. An evaluation of the experiment is presented, based on the results of a questionnaire completed by participants. The questionnaire and data on the distribution of responses are provided. Three conclusions are advanced: (1) the experimental teaching method seems to enhance the possibility of evolution and change in teaching; (2) correct choice of the medium to be used is of central importance; and (3) an experimental method such as this one should be modeled on traditional methods to avoid introducing too many uncontrolled variables.
