Abstract:

This study explored the effects of an assumed reading audience on expository writing. To elaborate a model of expository writing on scientific topics to accompany and promote scientific learning, the authors analyzed text content, designed and sequenced tasks for two science units, and incorporated expository writing tasks that assumed a role for the writer’s family and peers as assumed readers. They also examined actual student writing samples to identify the key features of student expository writing. From the 190 writing samples, based on 6 scientific tasks, of 36 fourth graders, it was found that students give different types of information and even of explanations to various assumed reading audiences. In general, the participating students could represent their conceptual and procedural understanding in written form. However, in writing that is intended to be read by family members there are more affective descriptions and the narrative forms are more creative. On the other hand, in writing intended for peers, students would focus on giving specific task instructions in guiding their peers. Based on the research findings, they suggested that science teachers should be aware of the influence of assumed reading audiences on students’ expository writing.
