Development of word reading fluency along primary education: a six-year follow-up / El desarrollo de la fluidez en la lectura de palabras en educación primaria: un seguimiento longitudinal de seis años.

Word reading fluency is a key component in the process of reading. In order to understand its acquisition it is crucial to conduct longitudinal studies. The aim of this work was to describe the development of word recognition in Spanish, considering accuracy and speed, from a longitudinal perspective. A group of 31 children were followed for six years. Reading performance was assessed with a list of 72 stimuli in which lexicality, frequency and length were manipulated. Results show that initial gains in reading accuracy occurred very rapidly. However, the growth of reading speed was found to be more difficult and complex, and automatic word recognition remains low at the end of Grade 6. Low frequency, long words were the most difficult stimuli. High stability in reading speed was observed and it was a relevant indicator that differentiates between good and poor readers. The findings also highlighted the need to develop training programs with the specific aim of improving word reading fluency throughout primary education. [ABSTRACT FROM AUTHOR]
