This article reports on a study which analysed the dialogue among students working in small groups. The main aim of the analysis was to identify types of interaction through the analysis of student-student talk. The study also examined the association between types of interaction and correctness of the answers provided by the students to the task. Results suggest that “dialogic interaction”, as a type of action based on the use of validity claims (including conjectures, reasoning and proof) within the dialogue, is associated with correctness, since participants must justify their answers drawing on validity claims that are susceptible of being verifiable by all participants in the group. The findings provide evidence to advance our knowledge about what is it about dialogic interaction that promotes learning, opening up new avenues for teachers to improve their practice within the classroom.

本文报告了一项研究，该研究分析了以小组形式工作的学生之间的对话。分析的主要目的是通过分析学生与学生的谈话来确定互动的类型。该研究还检查了互动类型与学生对任务提供的答案的正确性之间的关联。结果表明，“对话交互”作为一种基于对话中有效性声明（包括猜想、推理和证明）的使用的行为类型，与正确性相关，因为参与者必须根据易受影响的有效性声明来证明他们的答案组中的所有参与者都可以验证。研究结果提供了证据，以提高我们对促进学习的对话互动的认识，
