The advancement in technology and availability of Computer Mediated Communication (CMC) technology and the Internet made meaningful interaction possible in both on and offline environments, which is referred to as blended learning. Blended learning has recently begun to gain popularity in ELT, and appropriate models of blended learning need to be developed for EFL classrooms. However, there have not been many attempts to investigate its application and development of appropriate teaching and learning models of blended learning in the field of ELT, especially in relation to English language skills and subskills. Therefore, the purposes of this study are to investigate the students’ perspectives and effectiveness of blended learning in English pronunciation skills, and to explore gender differences in blended learning. The subjects of this study consist of 173 Korean university students, and quantitative data including questionnaire and pre-experiment were collected. The major findings of the study are as follows. First, students’ perspectives in blended learning, its components, and tools were very positive. Second, blended learning was found to be effective in the development of segmental and suprasegmental pronunciation skills. Third, there were few significant gender differences found regarding social aspects of online interaction. Implications and suggestions based on the findings and discussion are provided.

The purposes of this study are to examine the effects of the speech-analysis software on Korean college students' pronunciation improvement, and to find out ways to enhance the efficiency of computer-based visual feedback in the teaching of English pronunciation. The participants of the study are 89 English-major college students who are required and expected to have native-like pronunciation. A total of 178 recorded pronunciation data of pre-and post-tests were analyzed in terms of consonants, tense/lax vowels, consonant clusters, and phonological changes. The major findings of the study are as follows: First, the use of speech-analysis software was effective in improving the students' pronunciation. Second, the use of speech-analysis software was more effective at the discourse-level than at the word-in-isolation or sentence levels. In addition, it was more effective to students with low level pronunciation proficiency than those with high level proficiency. Third, the use of speech-analysis software was the most effective in training word-initial [h]-deletion of function words at the sentence level. Fourth, the participants responded that the visual feedback of speech-analysis program was useful in self-monitoring and self-correcting their pronunciation errors. Based on these findings, some pedagogical suggestions are made with respect to the didactic use of speech-analysis software in the teaching of English pronunciation.
