Research Aims This research aims to provide further
empirical research evidence examining reading development in children who have Down syndrome with implications for inclusive educational practices. Specific research focuses:
The benefits of intervention and early intervention on the reading development of children who have Down syndrome.
Phonological awareness. Reading comprehension. The implications of reducing oral language
demands of reading tasks.
![Page 10: Phonological awareness and ‘silent-reading’: The benefits of intervention and early intervention in reading for children who have Down syndrome. Kathy](https://reader035.vdocuments.site/reader035/viewer/2022062717/56649e445503460f94b3797d/html5/thumbnails/10.jpg)
Research Hypotheses Instruction in phonological awareness will
facilitate phonological awareness development. Reducing the oral language demands of reading
tasks will facilitate improved reading comprehension.
Reading instruction, particularly instruction focused on phonological awareness development, will facilitate improved phonological output.
Early intervention will be beneficial for reading development.
School-age intervention will also be effective for reading development.

Phonological awareness interventionIntervention steps:1. Oral reading of training words.2. Oral word reading and picture match (choice of two
pictures).3. Oral blending of an onset and rime presented orally only and
choose the corresponding picture (choice of three pictures). 4. Individual phoneme blending (plastic letters) orally and
visually, followed by picture match (choice of three pictures).5. Ask the participant to orally blend individual phonemes
(without plastic letters), make a picture match and put the picture in the box (Choice of three pictures).
6. Sentence completion (oral reading, three words to choose from, no picture).
7. Oral reading of training words.

Silent-reading intervention Intervention steps:1. Silent reading of training words.2. Silent word reading and picture match (choice of two
pictures).3. Silent reading of a short sentence then picture matching
(choice of three pictures). 4. Action task 1: Silent reading of a target word, then place
picture match in a box (choice of three pictures).5. Action task 2: Silent reading of an action sentence and
completion of the action (put the picture in the box/bag/hat) with the correct choice of picture (three possible pictures to choose from).
6. Sentence completion (silent reading, three words to choose from, no picture).
7. Oral reading of training words.

At the conclusion of the study all participants in both the phonological awareness and the silent-reading intervention groups showed improvement on all assessment tasks.
As indicated in the table on the following slide, a comparison of posttest mean scores for measures of phonological awareness are higher for the phonological awareness intervention group, while mean scores for measures of reading comprehension as well as measures of single real-word reading are higher for the silent-reading intervention group.
These results are consistent with the research hypotheses.

Implications of results for the 3-6 age group Given the successful progress made by
participants in the 3-6 age group the possible benefits of early intervention in reading for children who have Down syndrome needs to be explored further in the areas of: Phonological awareness

Conclusions Early intervention and school-age
intervention’s were found to be successful in facilitating reading development in this study.
The results of this study suggest that children who have Down syndrome can demonstrate phonological awareness and greater decoding skills after participating in phonological awareness instruction.
![Page 31: Phonological awareness and ‘silent-reading’: The benefits of intervention and early intervention in reading for children who have Down syndrome. Kathy](https://reader035.vdocuments.site/reader035/viewer/2022062717/56649e445503460f94b3797d/html5/thumbnails/31.jpg)
The results of this study suggest that reducing the oral language demands of reading tasks may facilitate reading comprehension for some children who have Down syndrome.
The results of the silent-reading intervention group also demonstrate that children who have Down syndrome demonstrate improved reading comprehension after engaging in reading comprehension tasks.
The results of this study provide support to the suggestion that reading development aids oral language development for children who have Down syndrome.
