The study investigated the usefulness of blogs in evaluating English-as-a-Foreign-Language learners' oral performance and explored their reactions toward using blogs as a learning and assessment tool for English-speaking performance. Fifty-one college students participated in a semester-long blog project, and each uploaded five audio entries to their individual blogs. The results indicated that the scores on the speaking blogs served as a significant predictor of students' oral presentation performance. Moreover, more than half of the participants considered their blogging experience positive. Close to half believed that the speaking blog constituted a good tool to showcase their learning process and help them reflect on their learning progress in the blog-based environment. However, only a few welcomed the idea of employing blogs as an assessment tool, while most still preferred the more conventional assessment methods, such as on-site speeches and presentations. These results carry pedagogical implications for foreign language instruction and assessment.
