The facilitative role of the interaction hypothesis: using interactional modification techniques in the english communicative classroom

Abstract

English language teachers are expected to implement lessons directed by the Communicative Language Teaching (CLT) into today’s classrooms. In this regard, it is pivotal to know about the theoretical framework of this key language teaching approach. The framework is partly made up of one of the most crucial Second Language Acquisition (SLA) hypotheses called the Interaction Hypothesis (IH). The IH claims that second language development is better facilitated when learners participate in negotiated interaction. From a CLT perspective, a second language is acquired more effectively through interaction and communication. When language teachers attempt to design and deliver classroom instruction grounded in CLT, it is imperative to be familiar with the essential notions behind the IH and its facilitative role in SLA. Therefore, this paper provides key information on the hypothesis at hand by analyzing its early version and updated version. In addition, Krashen’s comprehensible input and Hatch’s role of interaction and conversation on L2 learning are highlighted, because the IH evolved from these two scholars’ seminal works. This paper also deals with three key interactional modification techniques - comprehension checks, confirmation checks, and clarification requests – promoted by the IH. With the intent of facilitating language learning, the design and deliver of communicative-oriented lessons should have a central role in the classroom. However, lessons are more likely to be effective when teachers take the theory of the IH into practice by allowing learners to engage in negotiation of meaning through the use of the aforementioned interactional modifications.
