conversation analysis (CA)

Given the complexity of spoken interaction, acquiring conversation skills has been difficult for most EFL learners, and as EFL classrooms largely depend on hypothetical scripted material, learners lack explicit exposure to naturally occurring language essential for real - life interaction . This paper reports on a quasi - experimental study aiming at assessing the impact of conversation analysis- ( CA ) informed language - in -( natural )- talk log assignments on the development of Thai EFL learners ’ conversation skills . Eighty - eight second - year undergraduates at a university in southern Thailand took part in the study . As part of a monitored self - study task, the participants completed ten language - in - talk log assignments with self - selective use of audiovisuals available online . The quantitative data was collected using pre - and post - test role - plays . The qualitative data was assessed through completed log assignments, close analysis of the role - plays, and written interview for data triangulation . The findings suggested that the log assignment intervention significantly enhance participants ’ conversation abilities, including turn construction, turn delivery , and the sequential organization of turn - taking . The qualitative results also show that via CA - informed requirements of the log assignment, students became more aware of conversation mechanisms and language use in real - life interaction . This paper recommends that language - in - talk log assignments be incorporated into existing EFL conversation lessons .

The provision of scaffolding entails contingent assistance given to learners. Despite the proliferation of research on scaffolding, scant attention has been devoted to studying the modes of classroom interaction in fulfilling various scaffolding intentions in content-based instruction (CBI). To narrow the gaps, the present qualitative study embarked on an investigation of science teachers’ scaffolding in four modes proposed by Walsh (2006), namely managerial, classroom context, skills and systems, and materials modes. Four science teachers participated in this qualitative study, and 12 sessions of science classes were observed and analyzed deductively based on four classroom modes through conversation analysis (CA). The content analysis of the videotaped recordings indicated that managerial and materials modes were frequently used to enhance students’ comprehension and develop classroom interaction. The findings evidenced that pedagogical objectives were mostly related to cognitive structuring, contingency management, and direction maintenance requirements. Furthermore, the findings revealed that students’ engagement and involvement through recruiting interest was the only scaffolding intention employed in all four modes to involve students in the learning process. The findings can provide insights to teachers and teacher educators in the realization of distinct scaffolding intentions in various classroom modes by delineating the interrelationship between language use and teaching purpose.
