This study investigates middle school mathematics students' views and interpretations of graphical representations as they use graphs to answer algebraic questions--specifically, questions that require them to extrapolate information from graphs. From data gathered in videotaped interviews, students' verbal responses were analyzed as well as any gestures they used during the solution or answer phases. From the analysis of both response modalities, the constructs of bounded and unbounded views of graphs developed. The effects of these constructs and students' metaphors for the graphs were tested against the students' performance on far prediction tasks. Gestures provided a particularly useful window into students' views and predicted student performance on complex tasks more effectively than speech. (Contains 4 tables and 1 figure.)
