Audio CBTs: Measuring More through the Use of Speech and Non-Speech Sound.
Cynthia G. Parshall · 1999
Most computerized tests are simple applications that make limited use of the technology inherent in computer-delivered examinations. One potentially valuable feature of computer-administered examinations is the ability to play audio files, a function that makes it possible to incorporate sound into computer-based tests. Audio tests allow the potential improvement of measurement in familiar fields and expansion into new fields. This paper addresses some of the characteristics of the audio channel of communication, along with differences between audio and visual forms of communication and differences between speech and nonspeech forms of sound. Then, several specific types of uses for sound in computerized tests are suggested: (1) providing an alternative mode for communicating with the examinee; (2) testing listening skills in traditional areas; (3) testing listening skills in new areas; and (4) incorporating sound into the user interface. Discussion of both experimental and operational audio test is provided. The paper concludes with some cautionary statements and possible research directions. (Contains 29 references.)
