Roles, intents, and actions: First -year teachers' uses of discourse during elementary science instruction

William J. Newman, Purdue University

Abstract

In this study, I examined how three first-year elementary teachers constructed and used classroom discourse during science instruction. The three participants, though graduates from different universities, learned to teach science through similar science methods courses, which stressed the importance of inquiry-based science instruction. The participants taught different grade levels, and two of them taught at the same school. Data sources included field notes, videotapes, audiotapes, and semi-structured teacher interviews. While monologic and dialogic discourse existed in all three classrooms, monologic discourse was more prominent, especially when the discourse was teacher controlled. Dialogic discourse occurred most often during student-centered activities. The teachers constructed discourse with authoritative function to present science content and determine student comprehension. Generative function was most likely during student-based small group discussions. Monologic character often aligned with authoritative function, and dialogic character often aligned with generative function. However, monologic/generative and dialogic/authoritative discourse events did occur, contributing to the development of a discourse theory model. The teacher explanations for discourse included classroom control, inadequate planning, time constraints, life experiences, science education standards, and assessment. The teachers relied on their texts, kits, and state science standards to determine the content and methods for science instruction. They rarely reported that their science methods courses influenced how they taught science. The observed lessons rarely aligned with science education reform descriptions of appropriate science instruction. Implications include the need for in-service programs for beginning science teachers, curricular reform for science texts and kits, and explicit instruction of discourse strategies in science methods courses and in-service programs.
