Using conversational analysis as a methodological framework, this paper aims to analyze the sequential pattern of the turns in cooperative writing group interactions which unfolds solidarity building and disagreement episodes. Recorded verbal and non-verbal interactions of a group, comprised of ten members, were carefully transcribed to closely examine overlapping, latching, cut-off and other pragmatic cues of the turn taking. Results show that solidarity building is displayed using collaborative construction turn strategy and laughter strategies. Disagreement as a preferred act is an effective speech strategy that does not only use in pursuit of knowledge, but could also establish group cohesiveness. Data also opens implications for English Language Teaching (ELT) specifically in promoting pragmatic competence among Engliah as a Second Language (ESL) learners.
