In this paper, we examine the instructional discourse of science lessons in two primary classrooms for explanations of bird adaptations for flight.We drawon case study data to describe ways in which student construction of explanations is scaffolded by the teachers.We recognised three categories of explanations developed in the discourse: descriptive explanations, relational explanations and explanatorymodels.Descriptive explanations predominated. We argue that teachers cannot assume that, although the construction of oral explanations in science lessons may move from descriptive to relational or explanatorymodels, students will be able to write such explanations without specific attention to text structure.
