Abstract
Two studies investigated technical aspects of a computer-mediated test, the Computerized Oral proficiency Instrument (COPI), particularly in contrast to a similar tape-mediated test, the Simulated Oral proficiency Interview (SOPI). The first study investigated how examinees used self-assessment to choose an appropriate starting level on the COPI. The second study looked at examinees’ planning and response time on the COPI, and the factors that affected their use of time. Fifty-five university students took the COPI and SOPI in one of three languages: Arabic, Chinese, or Spanish. Results show that the majority of examinees (92%) were able to use the self-assessment instrument to select test tasks at appropriate difficulty levels. However, the COPI starting level (which was based on examinees’ self-assessment) might have been problematic for a small proportion (8%) of the examinees who appeared to choose tasks that were too difficult for them. As for planning and response time on the COPI, different amounts of time were used across four main levels of proficiency. Examinees with the highest proficiency levels tended to use less planning time but gave longer responses.
