摘要：This paper aims to investigate the influence of dialogic teaching on the development of the learners' speaking skills and critical thinking. It is questioning why Sudanese tertiary students are unable to express themselves efficiently and comfortably. This seems crucial and imperative for a college student and it shouldn’t shape any obstacle as a prerequisite for future development. Accordingly, this paper poses a significant issue that every learner of English needs to ponder. To collect data for the study, three tools has been used; a questionnaire, an interview and an observational checklist. The questionnaire was distributed throughout the students of second, third and fourth year university students who had been selected from different Sudanese universities. The collected data is analyzed quantitatively and qualitatively. Data analysis has shown that dialogic teaching enables students to develop the skills of argumentation, questioning and debate which contribute to the development of their critical thinking and speaking skills. Generally, the findings indicate that authentic dialogic teaching components are effective if students are given enough time to practice its skills. Hence recommendations for exposing learners to a variety of medium of speaking like dialogues, debate, argumentation and questioning are made to facilitate teachers to be more well-informed with dialogic teaching approach.
