Sight word reading in children with developmental disabilities using picture communication symbols : a comparative study

Brenda Fossett
2003
Historically, children with developmental disabilities were often excluded from literacy instruction, particularly i f they were non-verbal. A growing body of research suggests this population can develop sight word reading skills. Numerous methods have been investigated; paired associate research recommends that pictures be removed from reading instruction while stimulus fading and picture-to-text matching research advocates the use of pictures in reading instruction. The present study used an

The study compared two instructional conditions, paired associate learning and picture-to-text matching, and measured changes in participants' ability to match PCS to corresponding text. In the paired associate condition, PCS were always presented alongside text. In the picture-to-text matching condition, PCS were always presented separate from text. Results indicated that, for two participants, the picture-to-text matching condition was more effective than the paired associate condition for developing a small sight word vocabulary. The third participant was unable to complete the study due to difficulties in her personal life and did not demonstrate learning in either condition. Follow-up data for one participant showed that skills developed using the picture-to-text matching strategy were maintained up to 4 months after intervention. The results contribute to the existing research on sight word reading instruction and extend previous findings in a variety of ways. First, the study investigated the effectiveness of two different sight word instructional approaches, both of which used pictures. This was to clarify the role of pictures in sight word reading instruction. In addition, the study investigated two sight word instructional strategies that can [...]
