I assume that if they are identified as having dyslexia, they are receiving appropriate instruction in small groups.
If there are no provisions for small group instruction, that is an important first step. Students with dyslexia need explicit, systematic instruction in reading and other related skills, presented in small group settings. Neuhaus offers Basic Language Skills and Language Enrichment as two curricula that are beneficial for students with dyslexia.
Your question may pertain to how classroom teachers can help accommodate for students with dyslexia.
Here are accommodations suggested by Sally Shaywitz in Overcoming Dyslexia:
Provision of extra time for class assignments and tests
Quiet place for work completion
Recorded texts
Other accommodations might include:
Reducing the size of assignments without modifying the content
Use of computer software assistance with writing/spelling and reading
Reinforce phonemic awareness and systematic teaching of letter sounds in small groups
Read written directions aloud (this won’t hurt the rest of the class either!)
Dr. Shaywitz emphasizes that the most important accommodation for struggling readers is extra time, as the working memory is greatly slowed by the effort it takes to sound out words, especially at the beginning of reading development.
One additional note: Being especially attuned to and bringing out special gifts and talents helps all students, but especially those who are experiencing failure with literacy skills, which permeate just about everything that happens in school.
I hope this helps and that I answered your question. If the students do not have access to intervention with a specialist, it is imperative that these students participate in small group intervention which involves direct, explicit and systematic phonics instruction.
