This study aims to examine the learner perceptions and satisfactions of the level-differentiated college English classes and suggests more effective education program based on the survey results. The level-differentiated English program was designed to correspond to students’ needs and abilities and carried out as a pilot study. The classes were offered for four terms(20hours/ term), and each term had a six-tiered course. An online questionnaire was administered to 205 students. The results show that almost all the students were quite satisfied with the adequacy of the placement test. However, there was not statistically meaningful differences in students’ satisfaction with the level test. Students in lower levels such as level 1 and 2 were highly satisfied with the class operation and course in general, and seemed to get more benefits from the level-differentiated classes than intermediate and high level students. This result implies the level-differentiated curriculum is more necessary and effective for lower level students.

Purpose: This study aimed to measure the test-retest reliability of the Korean Matrix sentence-in-noise test in a sound-field testing condition. Methods: Fifty-five listeners with normal hearing participated. The sound-field speech-in-noise test was administered with a front loudspeaker by presenting noise at a fixed level (65 dB SPL) while adaptively adjusting the sentence level based on the listener’s response. The speech reception thresholds (SRTs) corresponding to 50% sentence-in-noise intelligibility were obtained using speech-shaped noise (SSN), International Collegium of Rehabilitative Audiology (ICRA) noise, and International Speech Test Signal (ISTS) noise. For the test-retest reliability, each subject was tested twice in a 2-week interval. The test-retest reliabilities were judged by the intraclass correlation coefficient (ICC), the minimal detectable change (MDC) values, and Bland-Altman plots. Results: The test-retest reliabilities of the Korean Matrix sentence test were good (ICC, 0.84~0.86) across SSN, ICRA, ISTS noises. The MDC was 0.92 dB SNR for SSN and 2.83 and 2.98 dB SNR for ICRA and ISTS, indicating the random measurement error varied across the types of noise. Conclusion: The Korean Matrix sentence-in-noise test can be used as a reliable tool to assess speech-in-noise intelligibility in sound-field testing condition. Further study across various sessions would strengthen the present finding.
