Aiming to provide a descriptive account of features of language learners' in-class responding behaviors, I collected data in four English classrooms in Taiwan by using various research instruments, including observation, interviewing and the questionnaire. Through the discourse/conversation analysis (Hsu, 2001), I show the naturally-occurring learners' verbal practice from different perspectives. The learners' common responding patterns were displayed first. Then, the learners were found to reciprocate their teacher's language use and tended to respond to teachers' difficult questions in their mother tongue. Also, L1 private speech in learners' responding practice assists them with maintaining inter subjectivity (Rommetveit, 1985), seeking rapport from their teachers, and externalizing their inner speech and feelings in the language classrooms. The analysis of the learners' verbal contribution here did not focus on quantitatively counting the word length learners produced, but attempted to demonstrate the learner's oral participation with a qualitative and narrative analysis.
