This article explores how a primary school teacher utilized the frameworks of dynamic assessment (DA) and the instructional conversation (IC) within a Spanish as a foreign language classroom. DA was used to construct zones of proximal development with individuals in the classroom context. A menu of pre-scripted assisting prompts, used to respond to predictable lexical and grammatical errors, permitted the teacher to assess students while also promoting development. ICs were used to co-construct a group zone of proximal development (ZPD) in response to less predictable student errors or inquiries. The flexible mediation provided by the teacher in these instances allowed for the active involvement of more students as well as more responsive dialogue. This language teacher drew upon these two frameworks to navigate dual goals of instruction and assessment while providing mediation attuned to the ZPD of the learners. As students studied interrogative formation to complete the pedagogical task of an interview, the teacher alternated between these two frameworks based on her goal for each 2 interaction. Class transcripts are analyzed to reveal how these two complementary frameworks can be used in conjunction to meet both the students' and teacher's needs.

I IntroductionSecond language (L2) teachers must decide how to respond each time a student makes an error or asks a question in the classroom. The teacher has a variety of response options: providing the correct answer, ignoring the problem, and calling upon the same or a different student for the correct answer are common examples (DeKeyser, 1993;Lyster, 1998). The teacher often has only a split-second before responding to consider the variables at play, such as the student, the context of the error, and the lesson objective. Student errors and questions not only allow teachers to see areas of struggle and misconception, but also offer an opportunity to promote language development (Aljaafreh & Lantolf, 1994). If a teacher's responses are not guided by any particular decision-making process or framework, these opportunities for development may be missed (Rea-Dickins, 2006 (Feuerstein, Falik, Rand, & Feuerstein, 2003;Feuerstein, Rand, & Hoffman, 1979), DA is based on the belief that a static evaluation of a child's present knowledge is not as revealing as a dynamic assessment of that child's future potential. Instruction and assessment occur simultaneously in DA in that a mediator promotes development by offering assistance to a student while concurrently assessing the student's abilities (Lantolf & Poehner, 2004;Lidz & Gindis, 2003). By attending to a learner's responsiveness to mediating prompts, a teacher may gain a clearer understanding of that student's future (Valsiner, 2001;Vygotsky, 1978). classroom context, no study has examined how these two frameworks can be used in conjunction to guide interaction. The present study examines ho...
