A Longitudinal Study of the Development of Reading Prosody as a Dimension of Oral Reading Fluency in Early Elementary School Children.

The purpose of this study was to examine the development of reading prosody and its impact on later reading skills. Suprasegmental features of oral reading were measured for 92 children at the end of grades 1 and 2 and oral reading fluency and reading comprehension assessments at the end of the third-grade school year. Tests were carried out to determine (a) the manner in which the key features of oral reading prosody unfold with development and (b) the extent to which the development of reading prosody is predictive of later oral reading fluency and comprehension outcomes beyond word reading skills alone. Path model tests found a relationship between the presence of fewer pausal intrusions during oral reading in first grade and subsequent development of an adult-like intonation contour in second grade. Outcome model tests indicated that the intonation contour was a significant predictor of later fluency once word reading skills were taken into account. Decreases in the number of pausal intrusions between the first and second grades and early acquisition of an adult-like intonation contour predicted better comprehension later. Thus, prosodic oral reading might signal that children have achieved fluency and are more capable of understanding what they read. Results of this study support the inclusion of prosody in formal definitions of oral reading fluency.
