This pilot study investigates how the use of audioblogs can help to meet an instructor's need to improve instruction in English as a second language (ESL). In this study, the instructor uses audioblogs to manage oral assignments, to interact with learners, and to evaluate performance outcomes. Learners record oral assignments through cellular phones, and maintain an individual audioblog in which they submit and archive the oral assignments. The instructor interacts with each learner through the individual audioblog to enhance his or her learning according to individual needs. Using mixed methodology (survey, open-ended questions, interview, and analysis of blogs), this study explores how the instructor's interaction with learners through audioblogs improves learners' oral English performance. The results indicate that the use of audioblogs meets the instructor's instructional needs, providing an efficient and effective way to evaluate students' oral performance and permitting individualized oral feedback. In addition, learners enjoy the ease of using audioblogs and believe that audioblogs assist their language-learning experience. This study also discusses the challenges that users of audioblogs face in the process of English-language instruction, and the implications of audioblog in language learning.
